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.

Description

technical field

[0001] The invention relates to the field of industrial degassing and dust removal, in particular to a Venturi scrubber and a desulfurization, depinning and dust removal system. Background technique

[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 has greatly reduced the gas treatment efficiency, espec...
