A waste gas constant flow treatment system

Abstract

The invention discloses a waste gas constant flow treatment system, which includes a buffer gas storage tank, the inlet of the buffer gas storage tank is connected to waste gas discharge equipment through an inlet pipe, and the outlet is connected to waste gas purification equipment through an air outlet pipe; the tank body of the buffer gas storage tank is provided with a second A vacuum gauge; the pipeline of the gas outlet pipe is sequentially provided with a shut-off valve, a vacuum pump and a second vacuum gauge along the gas outlet direction; the pipeline between the vacuum pump and the second vacuum gauge is also connected with a nitrogen filling device; the constant flow processing system also includes DCS , the first vacuum gauge and the second vacuum gauge are connected to the input interface of DCS, and the output interface of DCS is connected to the vacuum pump and nitrogen filling equipment; the exhaust gas discharge equipment discharges exhaust gas to the buffer gas storage tank through the intake pipe, and the DCS according to the vacuum degree of the buffer gas storage tank Control the operation of the vacuum pump to keep the exhaust gas flow constant; at the same time, DCS controls the operation of the nitrogen filling equipment according to the vacuum degree at the front end of the exhaust gas purification equipment fed back by the second vacuum gauge, so that the exhaust gas purification equipment maintains the inlet working pressure.

Description

technical field [0001] The invention relates to the technical field of industrial waste gas treatment equipment, in particular to a waste gas constant flow treatment system. Background technique [0002] Industrial waste gas refers to the gas containing pollutants produced by fuel combustion or process in the factory area of ​​the enterprise. Usually, industrial waste gas needs to pass through the waste gas treatment device to purify the waste gas before being discharged into the atmosphere. [0003] At present, there are four types of industrial waste gas treatment methods: [0004] 1. Electric capture method: Use high-voltage static electricity to capture harmful particles or tar in the gas. [0005] 2. Washing method: use water or other liquids to absorb or dissolve harmful components in the exhaust gas. [0006] 3. Adsorption method: It uses porous solid media or chemical preparations to accumulate or condense one or more components in the gas on the surface to achieve...

Problems solved by technology

However, if there are peaks and troughs in industrial exhaust gas emissions, and the peaks and troughs are very different, the design and processing of the equipment should be based on the peak data, which will lead to high equipment costs and increased later operation and maintenance costs. , especially in some special industries, the peak emission of industrial waste gas may be dozens or even hundreds of times of the valley value emission, which will lead to high cost of waste gas treatment
