Technical Field

[0001] The utility model relates to the field of waste gas treatment equipment, in particular to waste gas treatment equipment used for garbage incineration power generation. Background Art

[0002] As people's living standards improve, daily necessities increase, which also leads to an increase in domestic waste. Using garbage incineration to generate electricity is one of the ways to solve the problem of garbage. Using garbage to generate electricity can not only reduce garbage piles, but also eliminate the spread of bacteria and infectious diseases, while reducing environmental pollution and obtaining a certain amount of electricity. However, the waste gas generated by garbage incineration is the main pollutant. If it is directly discharged without purification, it will cause damage to the surrounding natural environment. Utility Model Content

[0003] In view of this, the utility model provides a waste gas treatment device for garbage incineration power generation, which can be connected and arranged by connecting the feed port on the dust removal box with the smoke outlet of the garbage incineration. When the high-temperature smoke from the incineration enters the dust removal box at the feed port, a dust removal component is provided in the dust removal box to filter impurities in the smoke. The filtered high-temperature smoke enters the heat exchange box through the delivery pipe from the discharge port. The heat exchange box is provided with a heat exchange component. The high temperature in the high-temperature smoke is recycled through the heat exchange component to reduce the direct discharge of the high-temperature smoke, so that the temperature of the surrounding air is increased, and the induced draft fan is started. The induced draft fan extracts the smoke in the heat exchange box and transports it to the denitration tower through the connecting pipe. The water pump is started. The water pump extracts the denitration agent in the water storage tank and sprays it into the denitration tower through the spray pipe. The connecting pipe is arranged below the spray pipe. When the smoke enters the denitration tower, the spray pipe sprays the denitration agent so that the denitration agent is mixed with the smoke, reducing the harmful substances in the smoke, so that the smoke can meet the emission standards.

[0004] In order to solve the above technical problems, the utility model provides waste gas treatment equipment for waste incineration power generation, including a heat exchange box, which is used to convert the high temperature in the high-temperature hot gas into high temperature through a conversion component.

A waste gas treatment component is provided on the other side of the heat exchange box, and the waste gas treatment component is used to treat harmful substances in the flue gas.

[0005] The dust removal assembly includes a dust removal box, which is used to filter dust in the flue gas. A feed inlet is provided on one side of the dust removal box to facilitate the flue gas to enter the dust removal box, and a discharge port is provided on the other side of the dust removal box to facilitate the discharge of the flue gas after dust removal.

[0006] A conveying pipe is connected between the dust removal box and the heat exchange box. The conveying pipe is used to transport the dust-removed flue gas to the heat exchange box. One end of the conveying pipe is connected to the discharge port, and the other end of the conveying pipe is connected to the heat exchange box.

[0007] An induced draft fan is provided on the side of the heat exchange box away from the conveying pipeline. The induced draft fan is used to extract the flue gas after heat exchange in the heat exchange box. The exhaust gas treatment components include a denitrification tower.

[0008] A connecting pipe is provided between the denitrification tower and the heat exchange box. The connecting pipe is used to transport the flue gas extracted by the induced draft fan into the denitrification tower. The connecting pipe is connected to the output end of the induced draft fan.

[0009] A water tank is provided on one side of the denitrification tower. The water tank is used to store denitrification agents. A spray pipe is connected between the water tank and the denitrification tower. The spray pipe is used to spray the denitrification agents. The spray pipe is arranged in the denitrification tower.

[0010] A water pump is connected to the spray pipe, and the water pump is used to extract the denitrification agent in the water tank. The extracted denitrification agent is transported through the spray pipe and sprayed into the denitrification tower.
