specific Embodiment approach

[0018] figure 1 A specific embodiment of the present invention is shown: a treatment equipment for volatile organic waste gas, wherein the treatment equipment includes a first processor 1, a second processor 2, an exhaust gas inlet pipe, an exhaust gas outlet pipe, a nitrogen circulation pipe 3, Gasifier 4, collection tank 7 and exhaust pipe blower 6, said nitrogen circulation pipeline 3 is at least partly located inside said first processor 1 and said second processor 2, said not placed in said first processor The nitrogen circulation pipeline 3 inside the device 1 and the second processor 2 is connected with an air inlet and an air outlet, and a vaporizer 4 is installed on the gas outlet, and the first processor 1 and the second processor The lower end of the processor 2 is provided with an exhaust gas inlet pipe, and the exhaust gas inlet pipe is connected with an exhaust gas blower 6, and the upper ends of the first processor 1 and the second processor 2 are provided with ...

Embodiment 1

[0022] The organic waste gas is passed into the inside of the first processor and the second processor through the exhaust gas blower from the exhaust gas inlet pipe (passing speed is 30cm 3 / min), injecting cryogenic nitrogen gas (with a temperature of -180°C) into the nitrogen circulation pipeline, and the cryogenic nitrogen gas is mixed with the cryogenic nitrogen gas inside the first processor and the second processor Heat exchange, when the temperature of the organic waste gas drops below the freezing point, organic waste is formed and adheres to the inner walls of the first processor and the second processor, and the cryogenic nitrogen gas after heat exchange is discharged from the gas outlet, and the heat After the exchange, turn on the hot air blowing device for 0.5h, heat, and raise the temperature of the organic waste to above the melting point, and flow it into the collection pool.

Embodiment 2

[0024] The organic waste gas is passed into the inside of the first processor and the second processor through the exhaust gas blower from the exhaust gas inlet pipe (passing speed is 50cm 3 / min), injecting cryogenic nitrogen gas (with a temperature of -150°C) into the nitrogen circulation pipeline, and the cryogenic nitrogen gas is mixed with the cryogenic nitrogen gas inside the first processor and the second processor Heat exchange, when the temperature of the organic waste gas drops below the freezing point, organic waste is formed and adheres to the inner walls of the first processor and the second processor, and the cryogenic nitrogen gas after heat exchange is discharged from the gas outlet, and the heat After the exchange, the hot air blowing device is turned on for 1 hour to heat up the organic waste to above the melting point and flow into the collection pool.

Abstract

The invention discloses a volatile organic waste gas treatment process and treatment equipment used in the treatment process. Deep-cool nitrogen released from a liquid nitrogen storage tank exchanges heat with organic waste gas in a first treater and a second treater, the temperature of organic waste gas can be reduced to be lower than the freezing point due to low temperature of nitrogen, the organic waste gas is attached to the inside of condensing equipment, volatile organic compounds such as benzene, methylbenzene, xylene and the like in the organic waste gas are liquefied to flow out through switching of ventilation and heating and are combusted as fuel, and the purpose of removal of harmful substances in the organic waste gas is achieved. The treatment process has the advantages as follows: 1, the investment is small, and the operation cost is low; 2, the content of harmful substances in exhausted gas is reduced, and the effect of up-to-standard release is realized; 3, in combination of direct combustion, condensed substances can be combusted without other fuel, the energy is saved, and the operation cost is effectively reduced.

Description

technical field [0001] The invention relates to a waste gas treatment process, in particular to a volatile organic waste gas treatment process and its treatment equipment. Background technique [0002] The degree of water pollution and air pollution around the world is becoming more and more serious. There have been many continuous and large-scale smog and water pollution incidents in the central and eastern regions of my country, which have also aroused the general attention and attention of the government, theoretical circles and people. It is inevitable to produce waste gas containing pollutants in industrial production activities. Although the current pollution control cannot achieve zero discharge of pollutants, the discharge and concentration of pollutants can be controlled within a certain range, that is, the discharge meets the standards. With people's attention and attention to environmental pollution, the environmental protection industry has also developed, the wa...
