Problems solved by technology

[0007] 2. It cannot alone undertake the purpose of one-time dust removal, it needs to be used with bag dust removal
[0008] 3. When dust is removed in a high temperature environment, the bag dust collector is easy to be burnt (the bag dust collector can only withstand a temperature of 260°), which affects the dust removal effect and increases the operating cost
[0009] 4. The failure of the dust removal system to operate normally leads to an increase in the operating rate and energy consumption of submerged arc furnaces and other kilns

Embodiment Construction

[0012] The exhaust gas dust shown in the cyclone dust collector (1) enters through the exhaust gas inlet of (5), and through the rotating centrifugal force and the down-spinning centrifugal guide groove (6), it is docked with the secondary spinning inlet (7), and passes through the fan after the pressurization and down-spinning In the atomization layer (8), the small dust particles are combined with water molecules through the atomization layer, and the weight of the dust increases, and the large dust particles after the fan atomization layer (8) formed by the atomization nozzle (2) will pass through the cone The trough (4) falls into the dust box through the direction of the arrows (10) and (16); the other part of the exhaust gas moves upward through the fan atomization layer (8) due to the pressure difference and enters the taper sleeve spinning with the upper and lower transparent openings The dust removal device (3), as shown by the arrows (9), (14), and (13), a part of the...

Abstract

The invention discloses an atomizing spinning dust removing device applied to an industrial cyclone dust collector. The vertically-transparent opened taper-sleeve spinning dust removing device is installed in the industrial cyclone dust collector, the opening size of the taper-sleeve spinning dust removing device is 160mm-320mm, the taper of the taper-sleeve spinning dust removing device is 16-32 degrees, and an atomizing spray nozzle is arranged under the taper-sleeve spinning dust removing device and above a taper blanking groove and forms a sector atomization layer under the taper-sleeve spinning dust removing device. The atomizing spinning dust removing device has a vertical dust flow circulating function, enables dust to be stacked mutually, improves the dust removing efficiency in waste gas by about 30% through atomization and secondary centrifuging based on increasing of dust weight, improves the particle size of removed dust by 0.01mm, does not need a cloth bag to assist in dust removal, can resist 700-degree of high temperature, further widens an application range and is environment-friendly.

Description

[0001] Application fields: [0002] The invention relates to an atomization spinning dedusting device used in industrial cyclone dedusters, mainly used in submerged arc furnace industry, iron and steel industry, cement industry, power generation and chemical industry and other industries. Background technique: [0003] Existing cyclone dust collectors can be divided into carbon plates, stainless steel, and ceramics from the production materials. The dust removal efficiency is generally about 75%. It is widely used in steel, submerged arc furnaces, cement, electric power, boilers and other environments with high temperature and relatively high dust concentration. Its main function is the first coarse cleaning, cooling, and some large Particle environmental dust removal, etc. [0004] In recent years, people have improved the traditional cyclone dust collector. A cone sleeve is installed inside the straight part of the cyclone dust collector, so that the original single cyclone...
