Dust and sulfur removal device

Abstract

The invention relates to a dust and sulfur removal device comprising a centrifugal separation mechanism and a purification mechanism; the centrifugal separation mechanism comprises a separation main body, a centrifugal shell fixed in the separation main body and a main shaft horizontally arranged in the centrifugal shell, openings communicated with the interior of the separation main body are formed in the upper end and the lower end of the centrifugal shell, an impeller is arranged on the main shaft, an air inlet is formed in the upper end of the separation main body, and an air outlet pipe is arranged at one end of the centrifugal shell; the purification mechanism comprises a purification box, an exhaust port and a water inlet pipe are arranged at the upper end of the purification box, an adsorption layer and a water outlet pipe are arranged at the bottom of the purification box, and the air outlet pipe is connected to the bottom of the purification box. By arranging the centrifugalseparation mechanism and the purification mechanism, step-by-step purification of dust and sulfur dioxide is achieved; through the centrifugal effect of the centrifugal separation mechanism, dust in flue gas is separated out through a physical method firstly, then sulfur dioxide in the flue gas is absorbed through the purification mechanism, and thus the use amount of water is greatly reduced, andthe purification cost is reduced.

Description

technical field [0001] The invention relates to the technical field of industrial purification equipment, in particular to a dust and sulfur removal device. Background technique [0002] Coal is widely used in various aspects such as industrial and agricultural production and residents' life. However, coal combustion will produce a large amount of sulfur dioxide, which can be dissolved in water to generate sulfurous acid, and the environmental pollution is quite serious. In order to eliminate the toxic and harmful substances discharged from coal-burning smoke exhaust, people have adopted various methods, such as wet dust removal method, cyclone dust removal, etc. The equipment used is large in size and high in cost. [0003] The Chinese utility model patent with the publication number CN201760206U discloses a dust removal and sulfur removal device for boilers, including a dust collector and a desulfurizer.

Problems solved by technology

However, coal combustion will produce a large amount of sulfur dioxide, which can be dissolved in water to generate sulfurous acid, and the environmental pollution is quite serious.

In order to eliminate the toxic and harmful substances emitted from coal-fired smoke exhaust, people have adopted various methods, such as wet dust removal method, cyclone dust removal, etc. The equipment used is large in size and high in cost

[0003] The Chinese utility model patent with the publication number CN201760206U discloses a dust removal and sulfur removal device for boilers, including a dust collector and a desulfurizer. The upper part is equipped with a water nozzle near the smoke outlet, and there are two downward-sloping upper water baffles and lower water baffles below the water nozzle and above the smoke inlet, and a sewage outlet is provided at the bottom of the shell. , the desulfurizer is equipped with sulfur-absorbing chemicals. The side bottom of the desulfurizer is provided with a smoke inlet connected to the flue gas outlet of the dust collector. Circulation pump connection, its disadvantage is that the dust removal and sulfur removal device consumes a lot of water during the treatment process, and at the same time causes water pollution in the dust collector
