酸洗塔

作者: 来源: 日期:2017-12-29 16:30:22 人气:250

设计考虑因素:
1.逆流式洗涤塔本体
A 耐真空:-300mmAq
B 耐压:+250mmAq
C 本体结构设计符合完整的基础支撑,顶端强度至少能支撑一个人的重量
D 人孔、视窗、喷雾系统及内部的支撑设计均应考虑所承受之压力及抗腐蚀性
2.洗涤塔如空与出口流速设计:
洗涤塔废气入口与出口流速设计必须防止气流产生空蚀现象。如果设计不良,空气流与洗涤液产生分道通过,将会大大降低洗涤塔的洗涤效率,入口设计流速必须考虑废气进入洗涤塔的气流能很均匀的分布于整个填充层的断面积
3.循环水槽:
洗涤塔最底层连接一循环水槽,提供洗涤塔有2-5分钟之循环水量,设计上注重于经济性,操作维修方便性与耐腐蚀性
4.洗涤及分布系统:
A 洗涤液可循环使用,亦可设计为批次操作或连续式自动操作,需要时补充少量新鲜之洗涤塔,以便在吸收污染物否尚能维持其效率
B 洗涤液分布设计中采用低压较大水量之喷嘴,发挥最大之均匀流率,达到最高之洗涤效率

如何选用洗涤塔:
1.确定废气污染源之成分、温度与湿度
2.确定欲处理之效率
3.确定处理风量选定型号
4.型号选定后,人孔、视窗、各管路表上未列之位置可依现场配合
5.确定洗涤塔之压降
标准配备:
在洗涤塔外壳或内部零组件的设计与整合会影响安装、操作及维护上的成本。本身标准配备如下:
1.洗涤塔内部结构
2.各种管配件,含给水、排水、溢流等
3.视窗、人孔:方便检修、清洗与填充材的取出与装入,或检查喷雾系统状况等
4.喷雾系统
5.填充材特拉瑞德
6.填充支撑架
7.循环水
8.、洗涤液循环泵浦
9.入口法兰
10.出口法兰
备选附件:
1.水位控制
2.水位计
3.流量计
4.加药系统
5.加药泵浦
6.加药桶槽
7.洗涤液备载循环泵浦
8.提高处理效率
9.PH控制系统
10.UV处理
11.循环水槽入孔
操作条件:
1.最大操作负压:-300mmAq
2.最大操作正压:+300mmAq
3.最高操作温度:+70℃

Design considerations:
1. counter - flow type washing tower body
A vacuum resistance: - 300 mmaq
B withstand voltage: + 250 mmaq
C body structure design conforms to the complete foundation support, the top strength can support at least one person 's weight
D manholes, windows, spray systems and internal support design shall take into account the pressure and corrosion resistance
2. design of washing tower such as empty and outlet flow rate:
The design of inlet and outlet flow rate of waste gas from washing tower must prevent cavitation. If the design is poor, the air flow and the washing liquid are separated, the washing efficiency of the washing tower will be greatly reduced
3. circulating water tank:
The bottom layer of the washing tower is connected with a circulating water tank to provide the circulating water quantity of the washing tower for 2 - 5 minutes
4. washing and distribution system:
A the washing liquid can be recycled or designed for batch operation or continuous automatic operation, with a small amount of fresh washing tower added as needed to maintain its efficiency when absorbing pollutants
B in the design of washing liquid distribution, a nozzle with a large amount of water at low pressure is used to exert the maximum uniform flow rate and achieve the highest washing efficiency
How to choose the washing tower:
1. determine the composition, temperature and humidity of the exhaust pollution source
2. determine the efficiency to be addressed
3. determine the selected model for handling air volume
4. after the model is selected, the positions not listed on the manhole, window and each pipeline table can be matched according to the site
5. determine the pressure drop of the washing tower
Standard provision:
The design and integration of the scrubber housing or internal components can affect the cost of installation, operation and maintenance. The standard itself is equipped with the following:
1. internal structure of washing tower
2. all kinds of pipe fittings, including water supply, drainage, overflow, etc
3. windows and manholes: easy maintenance, cleaning and filling material removal and loading, or check the status of the spray system, etc
4. spray system
5. filler, terrared
6. fill the support frame
7. circulating water
8. circulating pump of washing liquid
9. inlet flange
10. export flange
Alternate attachment:
1. water level control
2. water level gauge
3. flowmeter
4. dosing system
5. dosing pump pu
6. dosing tank
7. washing liquid standby circulating pump
8. improve processing efficiency
9. ph control system
10. UV treatment
11. circulating water tank into the hole
Operating conditions:
1. maximum operating negative pressure: - 300 mmaq
2. maximum operating positive pressure: + 300 mmaq
3. maximum operating temperature: + 70 ℃
