Acidic-exhaust gas treatment device with exhaust gas monitoring function

Abstract

The invention discloses an acidic-exhaust gas treatment device with an exhaust gas monitoring function. The acidic-exhaust gas treatment device includes a dust removal device, a liquid absorption device and a filter device which are sequentially arranged in the air flow direction, wherein the liquid absorption device includes a box body for holding an absorption liquid, a plurality of absorbing plates which are arranged at intervals in the box body in the air flow direction, stirring devices which are arranged in the box body, a gas circulating device and an absorbing liquid circulating device. According to the acidic-exhaust gas treatment device with the exhaust gas monitoring function, a good acidic exhaust gas treatment effect can be achieved through combination of the liquid absorptiondevice and the filter device, and an existing exhaust gas treatment technique can be supplemented and improved effectively; and the acid gas content of tail gas which is obtained through treatment ofthe acidic-exhaust gas treatment device can be monitored in real time through a gas monitoring device, so that the treatment effect of the acidic-exhaust gas treatment device is monitored.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an acid waste gas treatment device with tail gas monitoring function. Background technique [0002] With the rapid development of industrialization, a large amount of waste gas is inevitably produced, including a large amount of acid waste gas (such as a large amount of acid waste gas produced in the production process of many chemical products), acid waste gas mainly includes sulfur oxides, nitrogen oxides, H 2 S, chlorine, etc., a large amount of acid waste gas has caused the formation of acid rain. Acid rain has a great impact on the environment. Acid rain has the greatest impact on trees, which can be fatal and seriously affect the living environment of human beings. Therefore, the whole world pays special attention to the environment and formulates many measures. To reduce the production of factories that pollute the air, develop a green economy, and live a green...

Problems solved by technology

The treatment of acid waste gas has been paid attention to, but the existing acid waste gas treatment systems often have problems such as complex structure, large system, and poor waste gas treatment effect.

For example, the patent: CN206325369U discloses an acid waste gas treatment system, which includes a condenser, a buffer tank, a fan, a water washing tower module and a waste liquid pool; due to the use of large equipment such as the water washing tower module, the system is bulky and can consumes a lot

Another example is the patent: CN208372775U, which discloses a waste gas treatment system, including a first shell for holding the adsorption liquid. After entering the first waste gas inlet, the waste gas passes through a plurality of blades and is discharged from the first waste gas outlet. The waste gas treatment system described above also includes a second casing, the second casing is provided with a second waste gas inlet for the purified gas to enter, and a second waste gas outlet for the purified gas to discharge, which absorbs the adsorption liquid through the blades, and then the gas After passing through the blades, the harmful substances in them are absorbed by the adsorption liquid, which reduces the volume of the system. When the blades still need a driving device to drive the blades to rotate, the energy consumption is high. In addition, the gas treated by the blades directly enters the next operation, and there is a lack of waste gas treatment. The regulation function of the effect, and the lack of the monitoring function of the final exhaust gas composition
