Tail gas denitrification apparatus for fuel-gas generator

Abstract

The invention relates to a tail gas denitrification apparatus for a fuel-gas generator. The tail gas denitrification apparatus comprises a fuel-gas generator, a large-particle filtering net, a black smoke catalyst filter, a denitrification gas generation system, a water bath pond, a reactor, atmosphere, a flow rate controller and a thermometer, wherein the fuel-gas generator is successively connected with the large-particle filtering net and the black smoke catalyst filter by virtue of a gas pipeline, the denitrification gas generation system is communicated with the reactor by virtue of a gaspipeline, the reactor is arranged in the water bath pond, one end of the reactor is connected with the black smoke catalyst filter, the other end is connected with the flow rate controller or directly communicated with the atmosphere, one end of the thermometer is connected with the flow rate controller, and the other end is connected with the water bath pond. By adopting the tail gas denitrification apparatus of the fuel-gas generator provided by the invention, the content of nitride oxides in exhausted gas is reduced, the denitrified tail gas is discharged into the atmosphere after being processed in the water bath pond, and the pollution is greatly reduced.

Description

technical field [0001] The invention relates to a generator tail gas denitration treatment device, in particular to a gas-fired generator tail gas denitration treatment device. Background technique [0002] Distributed functional system is an advanced energy system technology widely used in developed countries and actively advocated by our government. The distributed energy supply system mostly uses clean energy such as natural gas. According to the principle of energy cascade utilization, high-grade energy is used for power generation, and low-grade energy is used for heating, cooling or dehumidification. energy utilization rate. [0003] The gas generator is the main prime mover of the distributed energy system. The working principle of the gas generator is as follows: the gas enters the gas generator, the air enters the mixer and mixes, then is supercharged by the flue gas turbocharger, and cooled by the cooler Enter the cylinder, ignite at high pressure through the spa...

[0003] The gas generator is the main prime mover of the distributed energy system. The working principle of the gas generator is as follows: the gas enters the gas generator, the air enters the mixer and mixes, then is supercharged by the flue gas turbocharger, and cooled by the cooler Enter the cylinder, ignite at high pressure through the spark plug, burn and expand, push the piston to do work, drive the crankshaft to rotate, and output electric energy through the generator. Nitrogen oxides have seriously exceeded the standard and have remained high, seriously polluting the air
