吉美福高达污泥干燥处理生产线冷凝功能描述

适用干燥机型号:17W240

设计提供方:吉美福高达,荷兰 二次设计:上海市政工程设计总院

制造商:北京碧福生环保工程设备有限公司

1 OVERVIEW OF THE PROCESS工艺概述

The GPD 17W240 sludge drying line is suitable to dry 6250 kg/h dewatered sludge @ 25% dry solids (hereafter called % ds) coming from the Kunming waste water treatment plant. This sludge is dried to a final dryness of 90% ds.

GPD 17W240污泥干燥处理线的干燥产量为每小时处理干物质含量为25%的脱水湿污泥6250公斤,脱水污泥来自昆明污水处理厂。最终干燥至干物质含量为90%。

The dewatered sludge @ 25% ds (hereafter called “wet sludge”) is fed in a constant flow of 6250 kg/h @ towards the wet sludge feeding nozzle on the paddle dryer. This nozzle is located at the top of the cover of the paddle dryer at the drive side of the dryer. Via this nozzle the wet sludge enters the drying chamber and falls down in the drying bed / sludge bed. In the sludge bed, two parallel paddle shafts are rotating in opposite direction, to create an intensive mixing and contact of the wet sludge with the heated walls of the paddle dryer. As a result of the

intensive contact of the wet sludge with the heated walls of the paddle dryer, the majority of the water content of the sludge is evaporated, to create a relative dry end product.

干物质含量为25%的脱水污泥(在此称为“湿污泥”)以6250kg/h的流速流向桨叶式干燥机湿污泥喂料口。喂料口位于桨叶式干燥机驱动侧机盖的顶部。通过喂料口湿污泥进入干燥室并落在干燥床/污泥床中。在污泥床中有两个平行的桨叶轴相向旋转,使得湿污泥充分混合并与桨叶式干燥机的加热壁充分接触。由于湿污泥与桨叶式干燥机加热壁的充分接触,污泥中所含的大部分水分被蒸发出来,获得比较干的最终产品。

Wet sludge is continuously fed at the inlet side of the dryer and dry product is continuously extracted from the dryer via a dry product overflow weir at the other end of the dryer. Because of this continuous feed and discharge of product, a more or less plug flow is created in the sludge dryer. Because of the plug flow, a continuous drying process is created.

湿污泥从干燥机入口侧连续进入,干燥产品通过干燥机另一侧的一个干燥产品溢流堰连续流出干燥机。由于物料的连续喂料和出料,在污泥干燥机中产生轻微的塞状流,因此干燥过程是连续进行的。

The dryer is heated with thermal oil which circulates through the paddle shafts, paddles and

jacket of the dryer trough. Also the cover of the dryer is heated with thermal oil via a heat tracing. The thermal oil is circulated with a thermal oil pump and re-heated in gas fired thermal oil heating system.

干燥机通过在桨叶轴、桨叶和干燥机机槽夹套中循环的导热油加热。干燥机的机盖也通过导热油伴热。导热油通过热油泵循环并在燃气热油加热系统中被重新加热。

The dryer is equipped with multiple water spray nozzles on the cover above the product bed. With this spray water the product temperature of the product bed temperature will be regulated to avoid too high product temperature and dust formation.

干燥机的物料床上方的机盖上配备有多个喷水嘴。通过向物料床喷水可以调节物料温度,以避免物料温度过高并产生灰尘。

There are 4 situations where spray nozzles are used:在四中状态下使用喷水嘴:

1. Start- up dryer干燥机启动

2. Too high product temperature物料温度过高 3. Too high level of oxygen O2氧气含量过高

4. Too high level of carbon monoxide CO一氧化碳含量过高

The dry sludge coming from the paddle dryer is cooled down in a cooling screw conveyor, immediately after leaving the dryer. The dry sludge is cooled down to prevent fire or explosion hazard by exposing the hot and dry sludge to the ambient air.

来自桨叶式干燥机的干燥污泥在离开干燥机后即在冷却螺旋输送机中被冷却。干燥污泥的冷却是为了防止高温干燥污泥暴露在环境空气中时发生着火或爆炸。

2

The water vapour coming from the dryer chamber is condensed in a 2 stage wet scrubber condenser system.

来自干燥机的水蒸汽在一个2级湿洗冷凝器系统中被冷凝。

In the first stage wet scrubber condenser, relative hot water is circulating to create condensation of the water vapour and washing out of dust which is carried over from the dryer.

在一级湿洗冷凝器中,较热的水循环流动使水蒸汽冷凝,并冲洗从干燥机中带出的灰尘。 The hot scrubber water is discharged from the bottom of the 1st wet scrubber (wet scrubber collecting sump) and pumped back to the scrubber water inlet of the 1st scrubber via a plate-type heat exchanger. The heat exchanger will cool down the scrubber water which has been heated up in the scrubber as a result of condensation of water vapour from the dryer. The heat extracted via the heat exchanger from the first stage scrubber can be used for external processes like heating up digestion tanks.

热冷凝水从一级湿洗冷凝器的底部排出(湿洗冷凝器收集池),经过一个板式热交换器被泵回一级湿洗冷凝器的水入口。热交换器使得由于干燥机水蒸汽冷凝而温度升高的冷凝水冷却。通过热交换器从一级湿洗冷凝器排出的热可用于外部其他工艺,例如加热污泥消化罐。

Upstream the scrubber water circulation pump, a self-cleaning filter is installed to remove the majority of the dust (sedimentation) in the scrubber water. As continuous condensing takes place inside the wet scrubber, an excess amount of scrubber water (condensate) is created. This excess condensate is discharged from the scrubber water recycle loop via the self-cleaning filter during the cleaning step. During cleaning of the filter, an amount of scrubber water is discharged from the circulation loop, including the accumulated dust on the filter deck.

冷凝水循环泵的上游安装一个自清洁过滤器以移除冷凝水中大部分的灰尘(沉积)。由于湿洗冷凝器中连续发生的冷凝作用,产生过量的冷凝水。这些过量的冷凝水在清洁时通过自清洁过滤器从冷凝水循环系统中排放出去。在过滤器的清洁过程中,一定量的冷凝水从循环中排放出去,同时带走在过滤器板上累积的灰尘。

The remaining vapours including the non-condensable gasses will leave the 1st wet scrubber on the top and are guided towards the inlet of the 2nd stage wet scrubber.

剩余的雾汽包括不可冷凝气体,从顶部的一级湿洗冷凝器离开并被引导至二级湿洗冷凝器的入口处。

The second stage scrubber is cooled with relative cold plant water which results in condensation of the remaining water vapour.

二级湿洗冷凝器用较冷的水,可以使剩余的雾汽冷凝

The non-condensable gasses are extracted from the 2nd stage scrubber via an exhaust fan. These non-condensables do contain odorous components, which can be post treated in a separate system (not included).

不可冷凝气体通过一个排风扇从二级湿洗冷凝器中排出。这些不可冷凝物含有味成分,可在一独

立的系统(不在供货范围内)内进行后处理。

DETAILED PROCESS DESCRIPTION WET SCRUBBER CONDENSOR SYSTEM湿式除尘冷凝系统工艺详述

1.1 WET SCRUBBER CONDENSER SYSTEM PROCESS DESCRIPTION

湿式除尘冷凝系统工艺描述

Info!注意!

Values listed/ mentioned with Functional Description are based on the „Guarantee Case Quantity“ case only!

功能描述中所列出/提及的值仅基于“保证运行工况的数量”!

The Wet Scrubber Condenser system (WSC) is designed as a two stage system. The two stage scrubber system enables heat recovery in the first stage at a high

temperature level and cooling down the remaining vapours and condensate in the second stage scrubber.

湿式除尘冷凝系统(WSC)设计为一个两段式系统。两阶段除尘系统可以在较高温度的第一阶段实现热回收并且冷却剩余蒸汽并在第二段除尘系统中得到冷凝。

Both condensers consist of a vertical hollow column, in which the majority of the water vapour coming from the dryer is condensed. Besides condensing the water vapour, first stage scrubber is also used to catch the dust which is carried over from the dryer with the vapours.

两个冷凝器都由垂直空心圆柱体组成,来自干燥机的大部分水蒸汽在圆柱体中被冷凝。除了冷凝水蒸汽,第一段除尘器也用于清除来自干燥机的水蒸汽中携带的灰尘。

The WSC is equipped with multiple spraying nozzles which create a condensing “shower” in the vertical column of the WSC. The water vapour will condense and is collected at the bottom of the WSC, where a certain condensate level is maintained. The excess condensate is being level controlled removed from the WSC.

WSC配备多个喷水嘴,可以在WSC的垂直圆柱体中形成冷凝“浴”。水蒸汽被冷凝并收集在WSC的底部,且冷凝水在此保持一定的水位。多余的冷凝水通过液位计排出WSC。

1st Condenser Stage:第1阶段冷凝器

The condensate from the bottom is re-circulated over the Condenser 41 000 via a filter 41030, pump 40000, and heat exchanger 41020. The automatic cleaning filter 41030 will separate the large fraction of the suspended solids, which are not settled out by gravity in the lower part of the WSC. The filtered condensate will be pumped via the heat exchanger 41020 to cool down the condensate and is recycled back to the spraying nozzles of the Condenser 41000.

来自底部的冷凝水通过一个过滤器41030、泵40000和热交换器41020重新循环至冷凝器41000。自动清洁过滤器41030将冷凝水中无法因重力沉淀而悬浮的大块固体物质分离出来。已过滤的冷凝水泵至热交换器41020得到冷却,然后在循环回冷凝器41000的喷水嘴。

4

The heat exchanger 41020 cools down the condensate and creates a hot water feed to the digesters of the WWTP. (Capacity depending on the case)

热交换器41020使冷凝水冷却、并产生热水供应污水处理厂的污泥消化池(产量依据案例而定)。

The temperature of the condensate is measured just before entering the spraying nozzles.

冷凝水的温度在进入喷水嘴之前测量。

2nd Condenser Stage:第2阶段冷凝器

Cooling water from WWTP will be pumped via pump 40010 to the spraying nozzles of the Condenser 41010. The temperature of the cooling water is measured just before entering the spraying nozzles.

来自污水处理厂的冷却水通过泵40010被送到冷凝器41010的喷水嘴处。在进入喷水嘴之前测量冷却水的温度。

The cooling water and the condensate will be collected in the sump of the condenser 41010 and then is being level controlled removed from the sump via pump 4015. 冷却水和冷凝水被收集在冷凝器41010的集水池中,集水池中的水位可以控制,多余的通过泵4015排出。

The non-condensable gasses will leave the both condensers at the top via a demister-pad. The demister will minimize the carry-over of water droplets from the WSC into the non-condensable exhaust.

The non-condensable gasses can be de-odorised in a post treatment system. 不可冷凝气体通过除雾器衬垫从冷凝器顶部排出。除雾器可以将来自WSC的水滴中携带的杂质降至最少并排入不可冷凝气体排气管。

1.6 START-UP CONDENSER UNIT AT AUTO MODE自动模式下冷凝器单元的启动

The Condenser Unit is operating by means of the central control room at manual or automatic mode. 冷凝器单元通过中央控制室控制,可手动和自动状态运行。 During manual mode the particular electrical drives and automatic valves can be actuated individually. 在手动状态下,个别电机和自动阀可分别启动。

During automatic mode the Condenser Unit starts in accordance with a hard-coded step rate (see chapter 6.3).自动状态下,冷凝器单元按照硬编码的步骤(见6.3章)启动 When plant is energized and „Automatic Mode Condenser Unit“ is chosen, alarm and switch points are activated.

当设备通电并选择“过滤器自动状态”时,报警和开关点均被启动。

Alarm/ switch points of particular control points are suppressed (see chapter 6.2).

Suppression ends with start-up Condenser Unit (see chapter 6.3).个别控制点的报警/开关点是被抑制的(见6.2节)。抑制末端即启动冷凝器单元(见6.3节)。

When the acceptance criteria given with chapter 6.1 meet the demands, the signal „Condenser Unit READY“ appears. Then the Condenser Unit can be started in automatic mode.

当6.1节的接受标准满足要求时,信号“冷凝器单元准备完毕”出现。冷却单元就可以在自动状态下启动。
