Negative pressure type purification tower for combustion waste gas treatment of multistage spraying contact reaction

Abstract

The invention discloses a negative pressure type purification tower for combustion waste gas treatment of a multi-stage spraying contact reaction. The negative pressure type purification tower comprises a bottom plate, a purification tower, a negative-pressure fan, a driving motor and a circulating water pump. The purification tower is fixedly mounted on the right side of the upper part of the bottom plate, a water storage chamber is arranged at the bottom of the purification tower, and a partition plate is fixedly installed in the middle of the water storage chamber. A chemical adding barrelis installed between the purification tower and an exhaust smoke pipe, and the lower end of the chemical adding barrel is connected with the upper portion of the water storage chamber through a chemical guide pipe. A stirring shaft is rotationally installed in the water storage chamber, and a rotary disc is fixedly connected to the left end of the stirring shaft. According to the negative pressuretype purification tower for combustion waste gas treatment of the multi-stage spraying contact reaction, a first filter plate, a second filter plate, a first connecting pad and a second connecting pad which are symmetrically distributed are arranged in a purification layer, and the purification effect of waste gas and the purity of the waste gas can be improved through the filtering effect of thefilter plates in cooperation with the sponge connecting pads and an activated carbon layer.

Description

technical field [0001] The invention relates to the technical field of combustion waste gas treatment, in particular to a negative pressure purification tower for combustion waste gas treatment of multi-stage spray contact reaction. Background technique [0002] Combustion exhaust gas contains a large amount of acidic substances, which need to be treated to meet the emission standards before they can be discharged, thereby avoiding the problem of air pollution. In the process of combustion exhaust gas treatment, negative pressure purification towers are often used to treat combustion exhaust gas, while the existing There are still some defects in the negative pressure purification tower for combustion exhaust gas treatment, such as: [0003] Existing negative pressure purification towers have poor effect on spraying waste gas, and are prone to incomplete reactions, resulting in acidic substances in the purified gas, and the existing purification towers have poor purification...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a multi-stage spray contact reaction negative pressure purification tower for combustion waste gas treatment, to solve the above background technology, the existing negative pressure purification tower has poor effect when spraying the waste gas , it is prone to incomplete reaction, resulting in acidic substances in the purified gas, and the existing purification tower has poor purification effect on exhaust gas, and it is inconvenient to scrape off the soot on the exhaust pipe when exhausting the flue gas , using the restricted problem
