Abstract

The invention belongs to the technical field of smoke removing, and discloses smoke removing equipment, comprising a smoke remover and a cyclone deduster, a water bath deduster and a clear water pool; a smoke outlet pipe of the smoke remover is connected with a wind inlet pipe of the cyclone deduster; a dust outlet pipe of the cyclone deduster extends below a liquid level of the clear water pool; a wind outlet pipe of the cyclone deduster is connected with the wind inlet pipe of the water bath deduster. The smoke removing equipment can avoid waste of absorption liquid and enables waste gas emission to more meet an environment-friendly standard.

Description

Smoke eliminating equipment

Technical field

The invention belongs to smoke abatement technical field.

Background technology

Shot (SteelShot) is the spherical particle that a kind of special material is made through special thermal treatment, is mainly used in the clear sand that shot is also widely used in cast(ing) surface.First melt high-quality bloom, then use high-pressure water jet on the refractory brick rotated, the molten steel of melting is formed microgranular, the ball body of formation reheats to purify homogeneous, and then Quenching Treatment.Ball body after quenching is dried and reheat tempering to reach applicable hardness in smelting furnace, is then sieved into the shot of different-diameter grade.

In shot production line, need to use intermediate-frequency heating furnace fusing bloom, what these intermediate-frequency heating furnaces were in a row is arranged on the kitchen range top, a large amount of useless flue gases can be produced in the process of intermediate-frequency heating furnace fusing bloom, traditional smoke eliminating equipment realizes smoke abatement by installing fume extractor on intermediate-frequency heating furnace, this smoke eliminating equipment directly will give up in flue gas importing absorption cell (inside filling absorbing liquid), and after pernicious gas is absorbed by liquid absorption, then the flue gas that will give up is discharged.

The shortcoming of said method is: 1. in useless flue gas, solid matter can be deposited in absorption cell, clears up, the absorbing liquid of some degree of not reaching capacity is discharged, can causes the waste of absorbing liquid like this after workman needs emptying absorbing liquid to the drift at the bottom of pond.2. because absorption cell is uncovered structure, pass into the useless flue gas not abundant haptoreaction with absorbing liquid in absorption cell, just emerge from absorption cell and be expelled in air, cause finally discharged useless flue gas not meet environmental protection index.

Summary of the invention

The invention is intended to provide a kind of and avoid absorbing liquid waste, discharge the smoke eliminating equipment more meeting environmental protection index.

Smoke eliminating equipment in this programme, comprise smoke expelling device, also comprise cyclone dust collectors, wet dust collector and clear water reserviors, the pipe of smoke expelling device is connected with the blast pipe of cyclone dust collectors, the dust outlet tube of cyclone dust collectors stretches under the liquid level of clear water reserviors, and the discharge pipe of cyclone dust collectors is connected with the blast pipe of wet dust collector.

Beneficial effect: this programme is accessing cyclone dust collectors after smoke expelling device, useless flue gas rotates after entering cyclone dust collectors, by means of centrifugal force solid particle be separated from air-flow and get rid of on the wall of cyclone dust collectors, solid particle slides to dust removing tube under gravity under wall, finally enter clear water reserviors, (arranging of clear water reserviors can prevent solid particle from flying upward); Then, the useless flue gas removing most of solid particle enters wet dust collector again, establishes absorption liquid pool in wet dust collector, can discharge after reaching discharge index after useless flue gas and absorbing liquid react.The present invention first uses cyclone dust collectors to process the solid particle in useless flue gas, prevent it from entering and absorb in liquid pool, prevent its alluvial in absorption liquid pool, another program, wet dust collector is uncovered structure not, by the mode of water-bath, flue gas is absorbed, compare and set up absorption liquid pool, the contact of useless flue gas and absorbing liquid and react more abundant.

Further, wet dust collector comprises shell, absorption liquid pool is provided with in shell, the free end of the blast pipe of wet dust collector shower nozzle is installed and stretch into receive liquid pool liquid level under, absorb the peripheral shell of liquid pool, form enclosure space in shell, gas has to pass through discharge pipe and could get rid of, compare the absorption liquid pool of traditional opened type, the useless flue gas situation Fang Sheng that abundant haptoreaction is just not emptying with absorbing liquid can be avoided.

Further, smoke expelling device was all be fixed on above heating furnace in the past, but the heating furnace kitchen range top of an actual shot production line there is multiple stage intermediate-frequency heating furnace usually side by side, the intermediate-frequency heating furnace of normal work is generally one or two, other intermediate-frequency heating furnace is in cooling, finishing, cleaning state, if add fume extractor on every platform intermediate-frequency heating furnace, then can increase equipment cost and equipment installation human cost, smoke expelling device is comprised the range hood be arranged on movably above heating furnace by this programme, without the need to being fixedly installed smoke expelling device corresponding with intermediate-frequency heating furnace, equipment cost spending is reduced by the mode reducing range hood quantity.

Further, clear water reserviors and absorb liquid pool pond at the bottom of be inclined-plane, the solid particle on inclined-plane in the effect lower slider of self gravitation to inclined-plane lowest part, easy solid particulate removal.

Accompanying drawing explanation
