Description
Technical Field
The utility model relates to a spray tower, in particular to a spray tower with a tower body separated from a liquid storage tank.
Background
The spray tower is a common waste gas treatment device, and is roughly classified into an integrated spray tower and a split spray tower according to the combination type of a tower body and a liquid storage tank, wherein the integrated spray tower is provided with the liquid storage tank at the bottom, and the liquid storage tank partially protrudes out of the tower body for inspection and maintenance. The tower body and the liquid storage tank (also called as a circulating water tank) of the split spray tower are of a split structure and are communicated through a water supply and return pipeline.
The split spray tower used in the prior art has a tower body which is higher than a circulating water tank in installation position, spray liquid is converged into the circulating water tank from a water outlet at the bottom of the tower body through a water discharge pipe by gravity drop, and the spray liquid is injected into a spray pipeline of the spray tower through a water supply pipeline after being subjected to physical treatment (such as filtration, oil-water separation, particle precipitation and the like) and chemical treatment (such as pH value adjustment) in the circulating water tank, so that the spray liquid is recycled. The bottom water outlet of the spray tower and the drift diameter of the connecting pipe of the bottom water outlet and the circulating water tank are provided with proper allowance in design, namely, when in use, spray liquid flows through the connecting pipe through gravity fall, a certain gap is formed between the spray liquid and the inner wall of the pipeline, and the gap causes bypass phenomenon, and the design method specifically comprises the following steps: when the spray tower operates at negative pressure (the exhaust gas exhaust fan is arranged at the rear end of the spray tower), ambient air is sucked into the spray tower from the gap, so that the loads of the spray tower and a rear induced draft fan are increased. When the spray tower runs under positive pressure (the exhaust gas exhaust fan is arranged at the front end of the spray tower), the exhaust gas enters the environment from the gap without being purified to cause pollution.
Disclosure of Invention
For solving the problem among the split type spray column prior art, the utility model aims to provide a technical scheme of spray column.
The utility model relates to an including the tower body, there is exhaust outlet at the tower body top, and there is waste gas entry tower body side below, and there is the outlet of intercommunication 180 degrees elbows tower body bottom, and there is the defogging device tower body is inside to be close to the waste gas outlet side, has the viewport in the top of defogging device, has more than two nozzles in defogging device below, nozzle and spray branch pipe intercommunication, spray branch pipe and the outside house steward intercommunication that sprays of tower body.
Furthermore, the waste gas inlet is provided with a water retaining elbow which extends into the tower body.
Furthermore, the water outlet is communicated with a section of 180-degree elbow, the elbow is arranged in the tower body, one end of the elbow is communicated with the water outlet, and a certain distance is reserved between the port of the other end of the elbow and the bottom of the spray tower.
Furthermore, the inspection port is communicated with the interior of the spray tower.
Further, the nozzle is directed directly downward and is in counter-flow with the exhaust gas.
Furthermore, the spray branch pipes are horizontally arranged in the tower body.
After the structure of the utility model is adopted, the utility model relates to a spray column can form the water seal by the elbow of bottom outlet intercommunication, prevents the waste gas bypass.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 10-a tower body, 11-a waste gas outlet, 12-a sight hole, 13-a demisting device, 14-a waste gas inlet, 21-a spray header pipe, 22-a spray branch pipe, 23-a nozzle, 24-a water outlet and 25-an elbow.
Detailed Description
The invention will be further explained with reference to the drawings in the following description:
the utility model relates to a including tower body 10, there is exhaust outlet 11 at tower body 10 top, there is exhaust inlet 14 tower body 10 side below, there is outlet 24 of intercommunication 180 degrees elbows 25 tower body 10 bottom, there is defogging device 13 tower body 10 is inside to be close to exhaust outlet 11 side, there is inspection hole 12 in defogging device 13's top, there are nozzle 23 more than two in defogging device 13 below, nozzle 23 and spray branch pipe 22 intercommunication, spray branch pipe 22 and the outside spray header 21 intercommunication of tower body 10.
Furthermore, the waste gas inlet is provided with a water retaining elbow which extends into the tower body.
Furthermore, the water outlet is communicated with a section of 180-degree elbow, the elbow is arranged in the tower body, one end of the elbow is communicated with the water outlet, and a certain distance is reserved between the port of the other end of the elbow and the bottom of the spray tower.
Furthermore, the inspection port is communicated with the interior of the spray tower.
Further, the nozzle is directed directly downward and is in counter-flow with the exhaust gas.
Furthermore, the spray branch pipes are horizontally arranged in the tower body.
In use, waste gas gets into the spray column by the waste gas entry, discharges from exhaust outlet via the defogging device after fully contacting with the atomizing liquid that sprays in the spray column, meanwhile, the liquid that sprays passes through the spray header that pump and supply channel were injected into the spray column by circulating water tank, gets into spray branch pipe by spray header, again by with spray branch pipe intercommunication the nozzle vaporific spray to the tower in with waste gas countercurrent contact, the liquid that sprays falls into the spray column bottom, because the return water mouth adopt 180 degrees elbow designs, spray liquid need gather the certain degree of depth at the spray column bottom and walk behind the elbow port just can discharge the tower body, so form the water seal in order to block the waste gas bypass.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, all the equivalent changes or modifications according to the features and spirit of the present invention should be included in the claims of the present invention.
