Technical Field

The utility model relates to a device for removing dust and smoke, in particular to a device for removing dust and smoke by a wet method.

Background

The dust and smoke removal is a technical measure for removing particles from dust-containing impurities, absorbing soluble gas into a product and reducing the emission of toxic and harmful gas to the atmosphere. The dust and smoke removing equipment is widely used for controlling the absorption of generated solid particles and soluble gases such as dust, smoke, ammonia gas, hydrogen chloride, hydrogen fluoride and the like, and reducing the emission of the generated solid particles and soluble gases to the atmosphere.

Dust and smoke are one of the main sources of air pollution, and acid rain formed by the dust and the smoke has great harm. Therefore, controlling the emission of dust and smoke is important for improving the atmospheric pollution condition.

At present, the dust removal and smoke removal technology is more developed, and mainly comprises bag type dust removal, electrostatic dust removal and wet dust removal; among them, there are cloth bag type, cyclone electrostatic type, water film type, spray type, water bath type and other dust removing techniques. Bag type, mechanical type and electric precipitation technologies only have a dust removal function and cannot eliminate toxic and harmful gases. The water film type, water bath type and spray type belong to wet dust removal, have the functions of removing dust and filtering harmful gases, but have the defects of large equipment volume, high energy consumption, large equipment maintenance and repair workload, low dust removal efficiency and the like, and are difficult to realize the ultralow emission standard.

In recent years, although the technologies are improved, the original technical principle is not separated, so that the technology has no major breakthrough. Other technologies such as spraying, atomizing, cloth bag adding and the like introduced from foreign countries (countries such as the United states, the Japan and the like) have no new breakthrough in principle, and the used equipment has high manufacturing cost.

Such as: (1) the cloth bag dust removal has large wind resistance, high energy consumption and poor fine dust treatment effect, and air compressors, electromagnetic pneumatic valves and other easily damaged auxiliary equipment and parts are needed, so that the maintenance workload is large; due to the existence of the cloth bag, the cloth bag can not be used for the smoke treatment of high-temperature environments such as an electric furnace and a cupola furnace; the cloth bag dust removal is dry dust removal, and toxic and harmful gases cannot be absorbed.

(2) The cyclone dust collection device has the advantages of simple structure, no moving parts, no fine dust removal and no absorption of toxic and harmful gases.

(4) The spraying dust removal equipment needs additional spraying auxiliary equipment, the sprayed water drops have large particles and small specific surface area, the sprayed water drops fall by gravity, the spraying airflow is limited, the unit volume treatment capacity is low, and the spraying water consumption is large.

(5) The spray dust removal equipment needs to be provided with an additional spray high-pressure pump and a spray nozzle, so that the water atomization energy consumption is high, and the nozzle of the spray nozzle is fine and easy to be blocked by impurities.

(6) The water film dedusting equipment has limited wind speed and low unit volume processing capacity, and when the wind speed is too high, the water film disappears to lose effectiveness.

(7) The water bath dust removing equipment has large wind resistance, high energy consumption, severely limited wind speed, difficult water level control and low unit volume processing capacity.

In summary, the prior art has the following drawbacks and problems: the dust removal efficiency is low, the effect is single, and the effect of treating complex dust is not good; the occupied area is large, and the investment is high; the hardening and blocking phenomena of the filter material often occur; the equipment has large system resistance, high energy consumption and high equipment operation cost.
