Problems solved by technology

[0002] Industrial degassing and dust removal equipment is widely used in various industrial and mining enterprises, such as washing and purifying various industrial dust-containing sulfur-containing and nitrate-containing gases; the Chinese patent document with the authorized announcement number CN202237668 discloses a venturi tube type gas scrubber It can be seen that the traditional Venturi scrubber has a large volume and relatively large energy consumption. Although it has a certain efficiency in boilers, kilns and corresponding desulfurization, denitration and dust removal systems, it is often transformed into a short-term scrubber due to the influence of construction site conditions. The Venturi system reduces the gas treatment efficiency greatly, especially the gas-liquid separation degree is not high, and it is difficult to meet the industrial requirements. Correspondingly, the traditional desulfurization, denitrification and dust removal system also has such problems

Abstract

The invention discloses a spiral venturi scrubber comprising a venturi pipe and a first water-sealing type water discharging device, wherein the venturi pipe is formed by connecting a retractable pipe, a compressed throat pipe and a spiral gradually-expanded pipe in sequence; the retractable pipe and the spiral gradually-expanded pipe are internally and respectively provided with first and second spraying and washing devices; and the bottom of the scrubber is provided with a water outlet which is connected with the first water-sealing type water discharging device. The invention further discloses a wet-method desulphurization and denitration dust-collecting system comprising a main desulphurization dust-collecting tower, a secondary desulphurization dust-collecting tower, a dehydrator and the spiral venturi scrubber; and the scrubber is communicated with the bottom end of the main desulphurization dust-collecting tower through a connecting flue; the top of the main desulphurization dust-collecting tower is communicated with the top of the secondary desulphurization dust-collecting tower through the dehydrator; and an air inlet of the secondary desulphurization dust-collecting tower is higher than the bottom surface of the dehydrator. The spiral venturi scrubber has the advantages of small volume, low energy consumption, high dust-collecting efficiency, good desulphurization and denitration effects and the like.
