A high temperature gas wet dust removal device

Abstract

The invention relates to a high-temperature gas wet type dust removing device. The high-temperature gas wet type dust removing device comprises a spray tower, an automatic draining demisting barrel and a clarifying tank, wherein the spray tower is communicated with the automatic draining demisting barrel by virtue of an air outlet pipe and communicated with the clarifying tank by virtue of a connecting pipe, a dust containing high-temperature gas inlet is formed in the side wall of the upper part of a cylinder of the spray tower, the lower end of the cylinder is communicated with a first conical barrel, the lower end of the first conical barrel is communicated with an expansion cylinder, the lower end of the expansion cylinder is communicated with a second conical barrel, the lower end of the second conical barrel is communicated with the upper end of a tee, the lower end of the tee is connected with two connecting pipes which are respectively communicated with two cylinders of the clarifying tank, and the expansion cylinder of the spray tower is communicated with the automatic draining demisting barrel by virtue of the air outlet pipe. Compared with a traditional spray dust removing device, the device has the characteristics of small size, compact structure, less water consumption, automatic separation of dust precipitation, simplicity in operation and the like, and separated water can be recycled.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a high-temperature gas wet-type dedusting device and an application method thereof. Background technique [0002] So far, for the refractory iron ore in our country, the high-temperature gas generated during magnetization reduction roasting contains both combustible components and a large amount of dust, which pollutes the environment and must be filtered before being discharged, and electric power cannot be used. Dust removal, bag dust removal and other dust removal methods can only be treated with water mist dust removal devices. However, the water mist dedusting devices currently used in the industry require a large amount of industrial water, and must be equipped with a special water treatment workshop, which requires large investment, high energy consumption, cumbersome operation, and serious waste of water resources.
