Industrial combustion coal gas filtering and purification device

Abstract

The invention relates to the technical field of environment protection equipment and discloses an industrial combustion coal gas filtering and purification device. The industrial combustion coal gas filtering and purification device comprises a bottom plate, wherein an air blower is fixedly mounted at one side of the top of the bottom plate; an air conveying pipe fixedly sleeves an output end of the air blower; a filtering tank is fixedly connected with one end of the air conveying pipe; one end of the air conveying pipe penetrates through and extends into the filtering tank; the bottom of thefiltering tank is fixedly mounted at the top of the bottom plate; and an air feeding pipe, which is located just above the air conveying pipe, fixedly sleeves the middle of one side of the filteringtank. According to the industrial combustion coal gas filtering and purification device disclosed by the invention, the filtering and purification device is internally provided with a steam turbine and a power generator; hot gas produced by industrial coal combustion is guided into the steam turbine through an exhausting pipe and the hot gas drives a fan blade in the steam turbine to rotate; and the fan blade drives a bearing to rotate and the bearing drives the power generator to rotate, and power is generated through the power generator, so that the aim of utilizing waste gas of the industrial combustion coal gas filtering and purification device is realized.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an industrial combustion gas filtration and purification device. Background technique [0002] Industrial combustion gas, also known as coke oven gas, belongs to high calorific value gas, crude gas or raw coal gas due to its many combustible components. A combustible gas produced at the same time as coke and tar products is a by-product of the coking industry. Coke oven gas is a mixture, and its yield and composition vary depending on the quality of coking coal and the coking process conditions. Generally, per ton Dry coal can produce 300m of coke oven gas under standard conditions 3 -350m 3 . [0003] In industrial production, it is often necessary to use the combustion heat of coal to process or produce products, such as metallurgy, hot forging, etc., because coal will generate a lot of heat during combustion, which is convenient for processing or ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a filter and purification device for industrial combustion gas, which has the advantages of waste gas utilization, high filtering and purification effect, energy saving and emission reduction, etc., and solves the problem that the hot gas will contain a large amount of hot gas when the coal is burned. A large amount of solid dust and harmful gas, the existing treatment method is to directly discharge the gas into the air after simple filtration and purification, a small amount of harmful gas will be discharged into the air to cause environmental pollution, and at the same time waste the heat in the hot air question
