Technical Field
The utility model relates to an exhaust-gas treatment equipment field especially relates to an exhaust-gas circulation sprays purifier.
Background
Chemical industry field can produce a large amount of acid-base waste gas in the manufacturing process, if directly discharge in the atmosphere, can cause serious pollution, common method discharges after carrying out neutralization through spray set, but traditional clarification plant simple structure that sprays, through shower spraying neutralization liquid, gaseous in-process that passes in spray passage is neutralized, but need use a large amount of neutralization liquid in this method, neutralization liquid after spraying discharges as sewage, with high costs and have secondary pollution's hidden danger, simultaneously because gas flow velocity is too fast, can't realize complete neutralization, influence purifying effect.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide an exhaust gas circulation and spray purifier.
The utility model discloses a realize through following technical scheme:
an exhaust gas circulation sprays purifier characterized by, includes: the gas enters the purifying box from the gas inlet pipe and moves towards the gas outlet pipe along a gas flow channel between the guide mechanisms, the circulating spraying mechanism sprays neutralizing liquid into the purifying box in the movement process, the gas is neutralized and purified under the action of the neutralizing liquid, and the neutralizing liquid is collected to the bottom of the purifying box and recycled under the action of the circulating spraying mechanism, so that the utilization rate of the neutralizing liquid is improved, and the purified gas is discharged from the gas outlet pipe;
the gas inlet pipe and the gas outlet pipe are respectively and fixedly connected to two ends of the purification box, the gas inlet pipe is arranged at the lower end of the purification box, the gas outlet pipe is arranged at the upper end of the purification box, gas enters the purification box from the gas inlet pipe and is discharged from the gas outlet pipe after purification, and the gas inlet pipe is close to the structure close to the upper part of the gas outlet pipe, so that the flow path of the waste gas in the movement process of the waste gas in the purification box can be increased, the contact time of the waste gas and the neutralization liquid is;
the guide mechanism comprises guide plates fixedly connected in the purification box at intervals up and down, the length of each guide plate is greater than half of the height of the purification box, a gap for gas to flow is reserved between every two adjacent guide plates, a gap is reserved between each guide plate and the opposite side of the purification box, and the waste gas moves forwards in an S shape in the guide mechanism, so that the flowing distance of the gas is greatly increased, the waste gas and the neutralizing liquid have enough contact time, and the acid and alkali substances in the waste gas are completely neutralized;
the circulating spraying mechanism comprises a spraying pipe fixedly connected in the purification box and a return pipe communicated with the bottom of the purification box, a circulating water pump is arranged between the spraying pipe and the return pipe, two ends of the circulating water pump are respectively communicated with the spraying pipe and the return pipe through pipelines, return branch pipes are communicated between two adjacent guide plates at the bottom of the purification box and communicated with the return pipe, neutralizing liquid sprayed out by the spraying pipe is collected at the bottom of the purification box, the return pipe is collected along the return branch pipes through the circulating water pump, and finally the neutralizing liquid is sprayed out again through the spraying pipe to form circulation, so that the utilization rate of the neutralizing liquid is improved.
Preferably, the intake pipe is provided with a check valve, so that gas can enter the purifying box through the intake pipe, and the neutralizing liquid cannot flow out of the intake pipe.
The utility model has the advantages that:
gas gets into the purifying box from the intake pipe in, is the S type and moves forward in guiding mechanism, greatly increased gaseous flow distance, make have sufficient contact time between waste gas and the neutralization solution, the motion in-process circulation sprays the mechanism and sprays neutralization solution to the purifying box in, ensures that the acid and alkaline material in the waste gas is by complete neutralization, and neutralization solution collects the purifying box bottom and recycles under the circulation sprays the mechanism effect, has improved the utilization ratio of neutralization solution.
