Description

High-efficiency adjustable impulse type dust remover

Technical Field

The utility model relates to a swash type dust remover especially relates to a swash type dust remover with adjustable it is high-efficient.

Background

The impulse type dust remover is widely applied to enterprises of metallurgy, coal, chemical industry, casting, power generation, building materials, refractory materials and the like, when the impulse type dust remover works, dust-containing gas enters the dust remover from an inlet, an airflow turns downwards to impact on the water surface, and part of larger dust particles fall into water. When the dust-containing gas passes through the S-shaped channel between the lower blade and the lower blade, a large amount of water splash is stirred up, so that the water vapor is fully contacted, most of fine dust particles are mixed into the water, and the dust-containing gas is fully purified. After passing through the "S" shaped channel, the water that has acquired the dust particles returns to the funnel due to the centrifugal force. The purified gas is discharged out of the dust removal unit through the gas purification outlet and the ventilator after water drops are removed by the water baffle of the mist separation chamber. The water level in the unit is controlled by an overflow tank. When the water level is higher than the overflow weir of the overflow box, the water flows into the water seal and is discharged by the overflow pipe.

93247151.X discloses a double-ring impact dust remover, which belongs to an industrial wet-type pool dust purification device and is suitable for the purification of flue gas of various furnaces and kilns. It is characterized in that a double-ring S-shaped water seal channel structure, a water-containing conical ash bucket direct-connection mud raking machine mechanism and an external water supply circulating system consisting of a flow-nourishing box, a chemical feeding water tank, a circulating water pump and a sedimentation tank are arranged at the communicated and rotating position of the flue inlet and the flue outlet. The dust remover is also provided with a water and ash containing bucket, an anti-freezing heat preservation layer structure of the mud raking machine and an ash blocking plate for overcoming the over-compaction of deposited ash. Compared with the dust remover of the same type, the volume is small, the manufacturing cost is reduced by 30 percent, the purification efficiency is up to more than 98 percent, the water consumption is minimum, and no pollution is caused. This patent changes water seal channel structure, increases dust collection efficiency.

CN 204352719U discloses a "high efficiency wet dust collector", this utility model relates to a high efficiency wet dust collector, including support frame, dust remover box, intake pipe, last blade, lower blade, breakwater, blast pipe, row's thick liquid valve, flushometer, delivery pipe and overflow pipe, its characterized in that: annular water outer spray nozzle is installed in intake pipe exit, water outer spray nozzle outer wall evenly is equipped with the inlet opening, water outer spray nozzle inner wall evenly is equipped with matrix form hole for water spraying I, the inlet opening outside is connected with water outer spray nozzle inlet tube, water outer spray nozzle sub-unit connection has annular intake pipe shower nozzle, intake pipe shower nozzle sub-unit connection has the reflecting disc, water outer spray nozzle middle part is equipped with shower nozzle in the water, shower nozzle outer wall is equipped with the matrix form hole for water spraying I just in the water, shower nozzle bottom is connected with water inner spray nozzle inlet tube in the water, intake pipe shower nozzle lower part border is less than the surface of water height under the dust. The dust collector has the advantages of simple structure and good purification effect, and fundamentally solves the problem of poor dust collection effect of the traditional impact type dust collector on dust in the dust-containing gas mass. The invention increases the water spraying device and improves the dust removal efficiency.

CN 2173108Y discloses "a gas induced dust remover" this utility model relates to a gas induced dust remover, is an improvement to the impulse type dust remover, changes "the upper and lower guide vane of" S "type passageway into the induced guide vane of" article "font of constituteing by upper guide vane, left guide vane and right guide vane, is equipped with narrow slit formula in the middle of left and right guide vane and spouts the mouth of nourishing, should spout the mouth and use the operation water head difference of" S "type passageway both sides as the power to" S "type passageway and spout the water, form big foam and mist foam under the gaseous phase induction to make gaseous abundant purification, and can increase the operation elasticity of equipment, maintain higher dust collection efficiency. This patent changes access structure, improves dust collection efficiency.

However, the existing impact type dust collector has the following defects:

1. The height of the water seal of the overflow water tank of the traditional impact dust collector is designed according to that the negative pressure in the mist separation chamber is not more than 400 mm water columns or the positive pressure in the mist separation chamber is not more than 150 mm water columns, an overflow weir can not be adjusted, and the overflow water tank needs to be additionally designed under the condition except the use condition.

2. When the working condition is poor, the water area of the impulse type dust remover can not fully capture the dust of the dust-containing gas.

3. The traditional impact type dust collector water baffle has poor dehydration effect, can only remove larger water drops, can not fully remove water vapor in flue gas, takes a large amount of water vapor out along with the flue gas, is supersaturated flue gas at the moment, and the water vapor in the flue gas is condensed in a flue and a fan quickly to cause certain corrosion to fan blades and pipelines.

In summary, the most important problems faced by the present impact dust collector are the overflow box adjustment problem, the dust collection efficiency enhancement problem and the dehydration problem.
