Description
Technical field
The present invention relates to technical field of waste gas treatment, more specifically, it relates to a kind of waste gas purification apparatus.
Background technology
Waste gas purification is primarily referred to as such as dust particle, flue gas flue dust, different of industrial waste gas caused by industrial site
The work that taste gas, toxic and harmful gas are administered.Common waste gas purification has factory's fume and exhaust gas purifying, workshop dust to give up
Gas purification, organic waste-gas purification, the purification of waste gas peculiar smell, acid-base waste gas purifying, purification of chemical waste gas etc..Industrial production discharge is given up
Gas, adverse effect often is produced to environmental and human health impacts, control techniques should be taken to handle before air is discharged into, be allowed to meet waste gas
The requirement of discharge standard, this process are referred to as waste gas purification.Conventional exhaust gas purifying method has：Absorption process, absorption method, condensation method
With four kinds of combustion method.
The patent of existing Application No. 201410720247.0 discloses a kind of infant industry spray tower for waste gas deduster, bag
Include tower body and be passed through the water inlet pipe of tower body, water inlet pipe is divided into three sections, and positioned at tower body top, injection flow rate regulation is provided with water inlet pipe
Valve, one end that sparge pipe is located in tower body are provided with atomizer, for spraying water smoke downwards, waste gas are sprayed, passed through
Chemical reaction removes removing exhaust gas.
But atomizer is located at the center of tower body, the fog concentration of ejection is gradually reduced to surrounding, therefore, leaned on
Waste gas at nearly tower body inwall can not be efficiently removed and be discharged, and atomizer, under, water smoke falls soon, with waste gas
Time of contact is shorter, and waste gas purification effect is undesirable.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of waste gas purification apparatus, it, which has, carries
The characteristics of rising waste gas purification effect.
To achieve the above object, the invention provides following technical scheme：
A kind of waste gas purification apparatus, including tower body, the air inlet in tower body side wall and the outlet positioned at tower body upper end
Mouthful, the tower body inner peripheral wall is coaxially arranged with annular conduit, and the annular conduit is arranged at intervals with several sprays communicated therewith
Mist mouth, the tower body lateral wall, which is located at below air inlet, is provided with the cyclic water tank connected with tower body, is set in the cyclic water tank
Reaction solution is equipped with, the drinking-water pipe and water pump being sequentially connected with circulating water chennel, the drinking-water pipe position are provided with outside the cyclic water tank
Tower body side wall is passed through in one end outside circulating water chennel, and is connected with annular conduit.
Preferably, the spray nozzle points at the axis of tower body obliquely.
Preferably, the spray nozzle and the angle on ground are 30 ° to 85 °.
Preferably, the cyclic water tank bottom is provided with discharge outlet.
Preferably, the discharge outlet is provided with draining valve, and the inwall of the cyclic water tank is provided with control at air inlet
The level sensor of opening and closing of drain valve processed.
Preferably, dosing tank and dosing pump are provided with above the cyclic water tank, control is provided with the cyclic water tank
The concentration sensor of force (forcing) pump dosing.
Preferably, the cyclic water tank bottom is provided with agitating paddle.
Compared with prior art, the invention has the advantages that：
By setting an annular conduit, and several sprays for pointing to tower body center obliquely are arranged at intervals on annular conduit
Mist mouth, spray nozzle is sprayed water smoke to tower body center, so as to remove most waste gas at including tower body inwall, lift waste gas
Clean-up effect；Due to nozzle obliquely, water smoke can stay aloft larger duration, further carry by projectile motion
Waste gas purification rate is risen；Fall behind under water smoke and return in the cyclic water tank of lower section, realization recycles；When in cyclic water tank due to anti-
During the hypervolia that should be generated, by level sensor, draining valve automatically opens up and discharges certain waste water；When reaction solution
When concentration is relatively low, concentration sensor automatically controls dosing pump to carrying out dosing in cyclic water tank, realizes automation dosing, recirculated water
The agitating paddle in bottom portion is used to medicament being well mixed, and improves the accuracy of detection.
