System for collecting and processing urban and industrial waste gas

Abstract

The invention discloses a collecting and disposing system of urban and industrial waste gas, which comprises a sewer pipeline. The invention is characterized in that the collecting and disposing system of urban and industrial waste gas also comprises a waste gas collecting pipeline which is arranged on the ground surface, and a mainline waste gas pipeline and a branch waste gas pipeline which are embedded underground; the mainline waste gas pipeline and the branch waste gas pipeline are provided with a fan respectively; the branch waste gas pipeline is connected on the mainline waste gas pipeline; the branch waste gas pipeline is connected with the waste gas collecting pipeline on the ground surface by a connecting pipeline; the connecting pipeline is inserted on the branch waste gas pipeline; furthermore, the outlet of the connecting pipeline inserted in the branch waste gas pipeline is provided with an anti-backtwist device. The waste gas collecting and disposing system of the invention carries out uniform collecting, concentrative disposing and concentrative exhausting on the waste gas exhausted by urban and industry, is convenient for monitoring the waste gas exhausting, and effectively reduces the cost of the waste gas disposal.

Description

technical field [0001] The invention belongs to the field of waste gas treatment, and relates to a waste gas collection and treatment system, in particular to a city and industrial waste gas collection and treatment system. Background technique [0002] There are three main sources of air pollution: [0003] (1) Industry: Industry is an important source of air pollution. There are many kinds of pollutants discharged into the atmosphere by industry, and their properties are complex, including smoke, sulfur oxides, nitrogen oxides, organic compounds, halides, carbon compounds, etc. Some of them are smoke and some are gas. [0004] (2) Living stoves and heating boilers: A large number of civilian living stoves and heating boilers in cities need to consume a large amount of coal. During the combustion of coal, a large amount of harmful substances such as dust, sulfur dioxide, carbon dioxide, and carbon monoxide will be released to pollute the atmosphere. Especially when heati...

Problems solved by technology

[0011] The current waste gas treatment is limited to small-scale local treatment, and most of them are designed for the emission equipment with serious waste gas pollution, or for the waste gas emission factories with serious pollution. This kind of factory builds waste gas treatment equipment by itself. The factory-based exhaust gas treatment system is not only costly, but the effect may not be satisfactory, and it also has the disadvantages that the exhaust gas emission cannot be monitored in real time, and the emission standard cannot be guaranteed.
