Embodiment 1

[0052] The present invention provides a volatile organic waste gas separation device, comprising a ventilation casing 1 with a double-layer outer wall structure, and a gap chamber capable of accommodating the circulation of organic waste gas is defined between the double-layer outer walls of the ventilation casing 1 . According to the invention, the directional exhaust of the organic waste gas is limited by the provision of a gas flow chamber 11 in the gap chamber, wherein the ventilation casing 1 is provided in its axial direction with a space capable of accommodating the separation unit 12 and is surrounded by the gas flow chamber 11 . The hollow inner cavity 13 is axially configured as a multi-level structure to accommodate the multiple components 3, 4, 7 of the separation unit 12, wherein the separation unit 12 is capable of extracting the multiphase entering the vent casing 1. It is arranged in the ventilating casing 1 in such a way that the organic waste gas in the volati...

Embodiment 2

[0081] The present invention also provides a method for separating volatile organic waste gas, the separation method comprising: selectively operating one or more components in the separation unit 12 to soften and pre-soften the multiphase extracting liquid entering the separation unit 12 through the ventilation shell 1 At least one of treatment, heating aeration and secondary separation, and directional separation of organic waste gas in the multi-phase extraction liquid in various paths, the separation unit 12 is used to detect the temperature of the multi-phase extraction liquid and the concentration of organic waste gas. way to control the selective operation of multiple components and the aeration amount of aeration to adjust the temperature of the multiphase extraction liquid.

[0082] according to figure 1 , figure 2 , the liquid flow direction S of the separated multiphase extracting solution of the present invention and the gas flow direction Q of the organic waste ...

Abstract

The invention relates to a volatile organic waste gas separation device which comprises a ventilation shell with a double-layer outer wall structure, and a separation unit capable of simultaneously separating organic waste gas in volatile multiphase extraction liquid and semi-volatile multiphase extraction liquid is arranged on the ventilation shell in the axial direction of the ventilation shell. One or more components in the separation unit selectively work to perform at least one of softening pretreatment, heating aeration and secondary separation on the multiphase extraction liquid, and directionally separate the organic waste gas in multiple paths; the separation unit is used for controlling the selective work of a plurality of assemblies and the aeration rate of aeration in a manner of detecting the temperature of the multiphase extraction liquid and the concentration of organic waste gas, so as to adjust the temperature of the multiphase extraction liquid. According to the invention, the application range is wider, the types of volatile organic compounds capable of being separated are more comprehensive, and meanwhile, the volatile substance separation efficiency is higher. The method is beneficial to ecological environment protection and sustainable development of ecological environment and economy.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to the technical field of organic waste gas treatment, and in particular to a volatile organic waste gas separation device. Background technique [0002] With the rapid development of industrialization, the massive emission of organic waste gas not only harms the ecological environment, but also restricts sustainable economic growth. In this context, the prevention and control of organic waste gas pollution has attracted widespread attention from the society. Solving this problem is not only beneficial to environmental protection, but also has important significance for economic development. Since many organic waste gases, that is, volatile organic pollutants, are relatively easy to diffuse and migrate in soil and groundwater, therefore, in groundwater pollution, it is very common for groundwater to be polluted by volatile organic pollutants. Organic pollutants incl...
