The invention relates to an exhaust gas recovery device of a chemical slurry filter press. The front and rear hood are installed on the front and rear sides of the cabinet filter press. A new air outlet is arranged on any hood, and one end of the recovery pipe is connected with the other end of the recovery pipe. The other end of the recovery pipe is extended into the recovery box, and a water recovery box is arranged in the recovery box. The other end of the recovery pipe is placed under the liquid level of the water recovery box, and the upper part of the recovery box passes through a suction pipe. Connect the fan, and there is a packing filter on the exhaust pipe; the water body recovery tank includes the first, second and third heating water tanks which are connected to the liquid level of the next heating water tank through the upper pipe in turn. The first, second and third heating water tanks are all equipped with electric heating wires, and the recovery pipe is extended under the liquid level of the first heating water tank, and the third heating water tank is connected with the recovery tank. Volatile solvents enter the water body recovery tank with fresh air through the recovery tube, and multi-stage heating water tank recovers single or multiple impurity solvents. The outlet of the recovery tank is filtered by packing filter to remove trace solvents and odors.

一种化工料浆压滤机废气回收装置
本专利技术涉及一种废气回收装置,具体说是一种化工料浆压滤机废气回收装置。
技术介绍
在化工生产压滤中,采用板柜压滤机过滤时,由于进料中含有易挥发溶剂,压滤过程中易挥发,气味难闻影响工作人员健康,且存在溶剂浪费。
技术实现思路
本专利技术提供了一种结构简单,能有效回收压滤机压滤作业时挥发的溶剂,确保工作人员健康安全,提高溶剂利用率,避免溶剂浪费的化工料浆压滤机废气回收装置。本专利技术的技术方案是:一种化工料浆压滤机废气回收装置,其特征在于:包括前、后风罩、回收管、回收箱、填料过滤器、风机,前、后风罩罩装于板柜压滤机的前、后侧,任意风罩上设有新风口,另一风罩上接回收管一端,回收管另一端伸入回收箱内,回收箱内设有水体回收箱,回收管另一端置于水体回收箱的液面下,回收箱上部经抽风管道连接风机,抽风管道上设有填料过滤器;所述水体回收箱包括上部依次经管道连通至下一加热水箱液面下的第一、二、三加热水箱,第一、二、三加热水箱内均设有电加热丝,回收管伸入第一加热水箱的液面下,第三加热水箱接回收箱。还包括尾部风罩,尾部风罩罩装于板柜压滤机非进料端,尾部风罩经尾部回收管连接回收箱并升入水体回收箱的液面下。本专利技术采用在压滤机的前、后侧以及非进料端推进压滤后部加装风罩,风机经抽风管抽风完成新风口的进风,挥发溶剂随新风通过回收管进入回收箱内的水体回收箱,被水体截留,多级加热水箱依次上部连通,每级内电加热丝加热温度不同,对单一杂质溶剂的吸收率提高,或可满足多种杂质溶剂的吸收使用,回收箱出风经填料过滤器过滤除去微量溶剂以及气味,提高操作人员环境安全,确保作业 ...
