Description

Waste-gas scrubbing device with rotary sprayer

The utility model relates to the waste gas dedusting device of worker, ore deposit enterprise and catering industry etc.

At present, the kind of industrial waste gas dust arrester is more, dust removal with machine is arranged, electric precipitation, the filter dedusting, wet scrubbing deduster etc., in these methods, the equipment that has is simple, but efficiency of dust collection is low, only can be used as elementary dedusting, the efficient that has is higher, but the equipment complexity, cost is expensive, and that general wet scrubber has is simple in structure, cost is low, efficiency of dust collection is than advantages such as height, but owing to disposable common spray or nebulization dust, efficiency of dust collection still is limited, moreover flue-gas flow rate is not definite value, and the blower fan of firm power will cause the waste of certain power when regulating flow like this.Even mixing in washing process contacts because gas is with liquid simultaneously, certainly lead to a large amount of drops, the drop that splashes in the air-flow, if after leaving disposable washer, can enter pipeline, ventilation blower, the chimney of back, enter atmosphere at last, may produce corrosion thus, wearing and tearing, obstruction, blower fan damage and problems such as atmosphere are arrived in pollutant emission.

The purpose of this utility model just provides a kind of simple structure, easy to use, the efficiency of dust collection height, and can make full use of power of fan, and can be to the device of flue gas cyclic washing.

Design of the present utility model is to utilize water as medium, or in additional and medicine, method is by central tube current to be assigned in each cross swivelling-nozzle, when current pass through the jet pipe nozzle ejection, produce reaction force, cause jet pipe to rotate around the center water inlet pipe, on rotational trajectory, form the several layers water curtain, on, when the jet pipe of following adjacent two layers is installed, water jet is towards rightabout, like this under the effect of reaction force, it is left-handed just to form one deck water curtain, the dextrorotation of one deck water curtain, help improving the collision opportunity of air-flow, when air communication out-of-date, under so intensive water curtain effect, solids such as dust just can obtain sufficient washing and depositing, gaseous contaminant is also washed, cooling, humidification, when the gas that has passed through washing for the first time enters when washing for the second time, the amounts of residual contamination do of once washing can be done the preceding washing of discharging, remove sedimentation, help improving wash degree, and the drop of gaseous contaminant is also further washed, reduced the pipeline of the gas of discharge the back, ventilation blower, the corrosion of chimney etc., wearing and tearing and pollutant are to the discharging of atmosphere.The exhaust gas flow that comes because of chimney variable often again, need regulate as the case may be, the waste that often causes the fanman to lead after the general waste gas dedusting device throttling, in order fully effectively to utilize power of fan, other is provided with a circulating water pipe and distributing valve, can both make full use of the power of blower fan with the unnecessary flow after the throttling as repeatedly washing, and can improve efficiency of dust collection again.For using water wisely, also be provided with water circulating pump, the water in the water tank can be used repeatedly.

The exhaust scrubber structure of described band rotary nozzle is to fix a distributing valve of regulating air-flow on chimney, be connected with a blower fan by the chimney behind the distributing valve, the air outlet of blower fan links to each other with the top cat head plate center hole of once washing tower by chimney, the water inlet of water pump is connected with suction hose, delivery port is connected with the mid point of center water inlet pipe, multilayer in one end of center water inlet pipe and the once washing tower, many swivelling-nozzle is connected, the other end and secondary washing tower lower end do not have base plate and all sit and be contained on the water tank and keep at a certain distance away, and there is an exhaust chimney at cat head plate center, secondary washing tower upper end.There is circulation pipe at one side place, water tank top, and circulation pipe communicates with distributing valve, and the water tank middle water level is no more than circulation pipe tube wall minimum point horizontal line.Swivelling-nozzle in two scrubbing towers all is to be the pipe that center symmetrical many, multilayer have the STH water jet with the center water inlet pipe.

Above-described water jet with layer swivelling-nozzle is all opened at the rear side with direction of rotation, and the water jet of the swivelling-nozzle of upper and lower adjacent two layers is then at reverse each other rear side.

What be worth to propose is that described swivelling-nozzle is to be sleeved on the water inlet pipe of center and can be rotated around the center water inlet pipe, all porose communicating in swivelling-nozzle and the center water inlet pipe.

In the above distributing valve be one while valve angle place that is connected the circulation mouth of pipe and rotating valve block.

The water sucking mouth of described suction hose is in water tank and be lower than horizontal plane.

The utility model has the advantages that simple structure, because of adopting the many processing and manufacturings easily of sheet metal structure, easy to use, the efficiency of dust collection height, and made full use of power of fan, owing to having adopted twice washing stack solids particle dust that caused not only washing and depositing, also removed the drop that produces in the duty, the burn into that has alleviated the equipment of scrubbing tower back stops up, damages.Alleviate the environmental pollution of gaseous state, saved water.

Below in conjunction with accompanying drawing embodiment is described in detail.
