Slanting grid type dust-removing and desulphurizing integrated device

Abstract

The invention discloses a slanting grid type dust-removing and desulphurizing integrated device, relates to the field of environmental protection equipment, and solves the problems in the prior art that the cost for the dust removal and desulfuration of tail gas is high, the possibility of blockage is high, and the like. A filter material pipeline I of the device and a regenerating device I are communicated with each other through a discharge device I; a filter material pipeline II and a regenerating device II are communicated with each other through a discharge device II; the included angle of the filter material pipeline I in a cylinder body and the inner wall of a cynlinder body, as well as the included angle of the filter material pipeline II in a cylinder body and the cylinder wall of the cylinder body are smaller than 70 DEG; a railing plate I and a railing plate II on each side are arranged from top to bottom at equal intervals, the outer end of each railing plate I is higher than the inner end of the railing plate I, and the outer end of each railing plate II is higher than the inner end of the railing plate II. According to the invention, the device is simple in structure, time-saving and labor-saving, convenient for operation, and high in purification efficiency, and reduces the cost.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an inclined grid type dust removal and desulfurization integrated device. Background technique [0002] Coal-fired boilers are widely used in thermal power, pharmaceutical and chemical industries. When coal is burned, a large amount of dust and sulfur dioxide are discharged into the atmosphere through the chimney, seriously polluting the atmospheric environment. At present, the flue gas of coal-fired boilers needs to be treated before being discharged into the atmosphere in order to meet the requirements of environmental protection. Some of the previous flue gas treatment devices are limited to dust removal, such as bag dust removal and water film dust removal; some are limited to desulfurization; and some are integrated. However, at present, the integrated structure of dust removal and desulfurization is basically to add desulfurization equipment to the dust re...

AI Technical Summary

Problems solved by technology

The filter material used in the dry purification of sulfur dioxide in the tail gas is usually activated carbon particles with a strong ability to absorb sulfur dioxide, and the activated carbon particles are basically filled in the channels in the cylinder through which the exhaust gas passes, and the two channels filled with activated carbon in the cylinder The end walls are equipped with more inlet plates with small air intake holes and air outlet plates with small air outlet holes. However, there are still some small particles of dust in the exhaust gas after dust removal, so the dust in the exhaust gas and the fine static After a period of time, the activated carbon particles in the state are easy to gather and cause the small air intake and exhaust holes to be blocked; at the same time, the dust on the blocked air intake and exhaust holes is also difficult to clean; When the bonded activated carbon seriously blocks the airflow in the cylinder, it needs manpower to clean it in time, which not only affects the normal production of the enterprise, but also requires a lot of labor, which is time-consuming and laborious; when the exhaust in the cylinder is not smooth, it will affect the dust removal effect of the entire purification device. Also affect the desulfurization effect
