Problems solved by technology

[0002] In addition to the use of solid materials such as silicon oxide, aluminum oxide, and molybdenum-nickel-tungsten in the traditional catalyst manufacturing process, a large amount of high-temperature hydrogen chloride, nitrogen oxide, and other waste gases are generated during the drying and roasting process. The exhaust gas emissions seriously affect the environmental sanitation of the site and surrounding areas. Even the formation of acid rain and other adverse consequences

Abstract

A multi-stage tank-type waste gas purifying and recovery device includes an air inducing system, a pipeline, a connection channel, a spray tank conical upper cap, a spray device, a maintenance baffle,a staged treatment tank, a device pedestal, a water tank, a water inlet channel, and a cyclone dust-air separation apparatus. The air inducing system is connected to the cyclone dust-air separation apparatus and is connected to the spray tank conical upper cap through the pipeline and the connection channel; the staged treatment tank is arranged under the spray tank conical upper cap; the spray device is arranged inside the staged treatment tank; the maintenance baffle is arranged on the side surface of the staged treatment tank; the staged treatment tank is arranged above the device pedestal; the water tank is connected to the spray device; the water inlet channel is arranged on the upper part of the water tank. The device can be used for waste gas absorption and treatment process in a catalyst drying and calcining process, can achieve the technical index of removal rate of waste gas being rich in hydrogen chloride, nitrogen oxides and dusts, and is low in operation cost.

Description

technical field [0001] The invention relates to the field of gas purification devices, in particular to a multi-stage tank type waste gas purification and recovery device. Background technique [0002] In addition to the use of solid materials such as silicon oxide, aluminum oxide, and molybdenum-nickel-tungsten in the traditional catalyst manufacturing process, a large amount of high-temperature hydrogen chloride, nitrogen oxide, and other waste gases are generated during the drying and roasting process. The exhaust gas emissions seriously affect the environmental sanitation of the site and surrounding areas. Even the formation of acid rain and other adverse consequences. With the development of the national economy, the problem of exhaust gas in the catalyst industry must be properly dealt with, and the exhaust gas treatment technology must be improved. Contents of the invention [0003] The purpose of the present invention is to purify the waste gas, and especially pro...
