Desulfurization device applicable to thermal power plant

Abstract

The invention belongs to the field of waste gas treatment, and particularly relates to a desulfurization device applicable to a thermal power plant. The desulfurization device comprises a purification box, wherein a reciprocating lead screw is arranged in and rotatably connected with the purification box, one end of the reciprocating lead screw penetrates through the purification box and is in transmission connection with a driving motor, and the reciprocating lead screw is in threaded connection with a threaded block; sliding grooves are formed in the inner walls of the two sides of the purification box and are jointly and slidably connected with a filter screen; the filter screen is connected to the threaded block in a sleeving mode; the purification box is rotationally connected with a plurality of water inlet pipes; the lower ends of the water inlet pipes penetrate through the purification box and communicate with spray heads, and the water inlet pipes jointly communicate with a multi-head pipe. According to the desulfurization device, purified gas can be prevented from being secondarily polluted through the arranged filter screen; in addition, the good filtering performance of the filter screen can be guaranteed through the arranged vibration mechanism; and waste gas purification efficiency can be effectively improved through the device.

Description

technical field [0001] The invention belongs to the field of waste gas treatment, in particular to a desulfurization device suitable for thermal power plants. Background technique [0002] A thermal power plant, referred to as a thermal power plant, is a factory that uses combustibles as fuel to produce electricity. Its basic production process is: when the fuel is burned, water is heated to generate steam, and the chemical energy of the fuel is converted into heat energy. The steam pressure drives the steam turbine to rotate, and the heat energy It is converted into mechanical energy, and then the steam turbine drives the generator to rotate to convert the mechanical energy into electrical energy. During the generation process of thermal power plants, a large amount of sulfur dioxide waste gas is often produced. In order to avoid the waste gas from polluting the environment, it is often necessary to desulfurize the waste gas. [0003] In the process of desulfurization treat...

Problems solved by technology

[0003] In the process of desulfurization treatment, the exhaust gas is generally passed directly into the ammonia water for desulfurization treatment, but the waste gas generally carries a large amount of impurities, and the direct introduction into the ammonia water will pollute the ammonia water, and the purified gas cannot be directly mixed with the impurities. Separation will easily cause secondary pollution, increase the link of subsequent filtration, and greatly reduce the purification effect of exhaust gas
