Laboratory exhaust gas treatment system

Abstract

The invention relates to a laboratory exhaust gas treatment system. The laboratory exhaust gas treatment system comprising a heating device, an exhaust gas purification tower, a filter device, an induced draft fan and a gas discharge part is characterized in that the heating device, the exhaust gas purification tower, the filter device, the induced draft fan and the gas discharge part are sequentially connected through a pipeline; from top to bottom, the inner portion of the exhaust gas purification tower is sequentially provided with a liquid storage part, a packing layer, s sprinkler systemand a defogging layer; the liquid storage part is connected with the sprinkler system through a circulating pipe and a circulating pump; the exhaust gas purification tower is connected with a dosing device through the pipeline; frequency conversion devices are respectively arranged on the induced draft fan and the circulating pump; a wind pressure transmitter is disposed on a laboratory exhaust gas collection pipeline connected with the heating device. The laboratory exhaust gas treatment system has the advantages that the arrangement of the heating device facilitates the reaction between exhaust gas and absorption treatment liquid, thus improving purification effect; with the arrangement of the wind pressure transmitter and the frequency conversion devices and with the power supply frequency of the induced draft fan and the circulating pump adjusted according to the wind pressure transmitter, while exhaust gas absorption is ensured to be of good effect, energy savings are maximized, and the effect of energy conservation and emission reduction is achieved.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a laboratory waste gas treatment system. Background technique [0002] In the laboratory, chemical experiments will produce harmful exhaust gases such as acid gas and poisonous gas. The pure ventilation equipment can only promote the convection of the environment inside and outside the laboratory, and directly discharge the harmful gas that has not been purified into the atmosphere, causing damage to the environment. negative effect. At present, laboratory waste gas treatment equipment is often not designed according to the characteristics of laboratory waste gas "indeterminate and quantitative", so there is a problem of energy waste, and there is room for improvement in gas purification effect. Therefore, it is the problem to be solved by the present invention to provide a laboratory waste gas treatment system with simple structure, energy saving and good purification effect....
