Abstract

The invention relates to an environment-friendly treatment system for acid fog from an exhaust fan of a chemistry laboratory. The system includes: a ventilation hood, an air compressor, a Raoult jet pipe, an atomization absorption tube, an alkali liquid trough, and a gravity separation chamber. The air outlet of the ventilation hood is connected to the air inlet of the air compressor through a pipeline; one end of the Raoult jet pipe is connected to the air outlet of the air compressor, while the other end of same is connected to the inlet of the atomization absorption tube; the atomization absorption tube is connected with the gravity separation chamber on which an exhaust port is formed, wherein the exhaust port and the atomization absorption tube are located on the same side of the gravity separation chamber; a filter screen pad is arranged on the exhaust port; the atomization absorption tube is provided with a liquid suction hole, which is connected with a thin tube and communicated with interior of the alkali liquid trough. Compared with the prior art, the system has high absorption efficiency and is low in possibility of leakage of acidic gases.

Description

technical field [0001] The invention relates to a waste gas treatment system, in particular to an acid mist environmental protection treatment system for a chemical laboratory exhaust fan. Background technique [0002] With the development of science and technology in our country, the demand for various laboratories is increasing, and key laboratories of various disciplines, schools, and key laboratories in various systems emerge in an endless stream. We have always paid great attention to the waste gas treatment of large-scale industrial production, but often neglect the treatment of laboratory waste gas. Although the emission of laboratory exhaust gas is generally small, the sum of the long-term accumulation is extremely considerable. Moreover, different from standardized industrial processes, the types and concentrations of pollutants contained in laboratory exhaust gas are often more diverse and unpredictable, and some chemical substances with special toxicity are more ...
