Problems solved by technology
Exhaust gas catalysis can only catalyze part of the exhaust gas at low temperature, and has a narrow scope of application. It cannot treat all exhaust gas. Although incineration treatment can carry out high-temperature incineration and cracking of all exhaust gas, it requires secondary energy consumption.

The invention discloses a waste gas treatment and utilization system capable of achieving high-temperature incineration and low-temperature catalysis. The system comprises a waste gas heat exchanger, a refrigerant inlet of the waste gas heat exchanger is connected with an organic waste gas conveying pipeline provided with a waste suction fan, a refrigerant outlet of the waste gas heat exchanger is connected with a gas inlet of an incinerator through a pipeline provided with a third valve and a fourth valve, a gas outlet of the incinerator is connected with a heating medium inlet of the waste gas heat exchanger through a pipeline, and a heating medium outlet of the waste gas heat exchanger is connected with a heat supply pipeline provided with a heat supply fan. By means of the above-mentioned scheme, one system had two waste gas treatment functions, the different treatment functions are selected and switched according to differences of waste gases, the use cost is low, production operation is convenient and flexible, the treatment advantages of being capable of saving energy and low in cost of low-temperature catalysis are utilized, consumption of secondary energy in the treatment process is reduced, and therefore the treatment cost is reduced; meanwhile, waste gases which cannot be treated through catalysis are treated by means of the advantage that high-temperature incineration can be used for treating all the waste gases.
Description
[0001] Technical field: [0002] The invention relates to a high-temperature incineration low-temperature catalytic waste gas treatment and utilization system. [0003] Background technique: [0004] At present, there are two ways to discharge waste gas: one is direct discharge, which will cause serious pollution of the environment and waste of energy. The second is to recycle heat energy after incineration treatment, and the third is to recycle heat energy after catalytic treatment of waste gas. Exhaust gas catalysis can only catalyze part of the exhaust gas at low temperature. It has a narrow scope of application and cannot treat all exhaust gas. Although incineration treatment can carry out high-temperature incineration and cracking of all exhaust gas, it requires secondary energy consumption. [0005] Invention content: [0006] In order to make up for the deficiencies of the existing technology, the present invention provides a high-temperature incineration and low-tempe...
