Flue gas desulfurizing and dust removing device applied in field of environment protection

Abstract

The invention discloses a flue gas desulfurizing and dust removing device applied in the field of environment protection. The flue gas desulfurizing and dust removing device includes a gas inlet pipeline, a desulfurization box, a connection block and support legs; the lower end of the gas inlet pipeline is connected with a dust removing cavity, an adsorption plate is transversely arranged inside the dust removing cavity, one side of a circulation cavity is fixedly connected with one end of a first connection pipeline, a reaction pool is formed in the desulfurization box, the other end of the first connection pipeline penetrates through the side wall of the desulfurization box and is connected with the reaction pool, a sewage pipeline is fixedly connected to the lower end of one side of thedesulfurization box, the other side of the desulfurization box is fixedly connected with one end of a second connection pipeline, the other end of the second connection pipeline is fixedly connectedwith a filtration box, a filtration plate is fixedly connected to the upper end of the connection block, a connection plate is arranged between the support legs, an exhaust fan is fixed to the upper end of the connection plate, and the other end of the exhaust fan is fixedly connected with a gas outlet pipeline. By the adoption of the flue gas desulfurizing and dust removing device applied in thefield of the environment protection, the problems are solved that current flue gas desulfurizing and dust removing devices are pool in airtightness and not convenient for later maintenance, besides, waste heat of flue gas cannot be fully utilized, and then energy waste is caused.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a flue gas desulfurization and dust removal device used in the field of environmental protection. Background technique [0002] Smoke is a mixture of gas and smoke and is the main cause of air pollution in residential areas. The composition of the flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides. The smoke includes fuel ash, coal particles, oil droplets, and pyrolysis products. The flue gas contains a large amount of toxic gases (CO, SO2), and the suspended particles in the flue gas are also harmful. Due to the effect of gas diffusion, the floating dust with small particle size in the suspended particles can enter the human lungs and adhere to and gather in the alveolar wall. It can be sent to the whole body with the blood, causing respiratory diseases. [0003] Th...
