Description
Technical field
The present invention relates to a kind of scrubbing tower, particularly a kind of scrubbing tower for the treatment of low-emission coated tail gas.
Background technology
In recent years, along with the development of urban industry, atmosphere pollution is day by day serious, and air quality worsens further, and environmental problem becomes global problem.Scrubbing tower is a kind of novel gas purification treatment facility, is widely used in an important step in the purified treatment of industrial waste gas.The high-temp waste gas composition that Low emissivity on-line coating produces is comparatively complicated containing acidic materials and larger dust, and in lessivation, have foam to produce, if directly discharged, very serious pollution is caused by environment, therefore, must purified treatment be carried out before discharging waste gas, make flue gas effectively be cooled and purify, and then discharge, be conducive to the sustainable development of environment.This just requires that on-line coating tail gas clean-up scrubbing tower stability is good, safe and efficient, operating cost is low, can process the waste gas of high temperature highly corrosive and complicated component.Through extensively retrieval, not yet find ideal technical scheme.
Summary of the invention
The object of the invention is to solve present stage existing scrubbing tower process high temperature, acidity, dust-laden and the inefficient shortcoming of plated film waste gas such as fluorine-containing, and a kind of scrubbing tower for the treatment of low-emission coated tail gas proposed.。
To achieve these goals, present invention employs following technical scheme:
For the treatment of a scrubbing tower for low-emission coated tail gas, comprise tower body, be provided with gas outlet, lower end be provided with outlet of sewer in the upper end of tower body, the sidewall of tower body lower end is also provided with air inlet, tower body connects alkali lye source by shower, it is characterized in that:
A, in tower body, be provided with one group of spray district successively, spray district is all arranged on the top of air inlet, and described spray district comprises packing layer, and above packing layer, correspondence arranges shower, and shower is provided with the opening corresponding with packing layer;
B, be also connected air distribution plate in tower body, and uniform one group of passage on air distribution plate, air distribution plate is arranged between undermost spray district and air inlet.
On the basis of technique scheme, following further technical scheme can be had:
Described packing layer comprises the string bag, in the string bag, be provided with inserts, and the string bag is connected on the inwall of tower body, and the inserts of the superiors' packing layer is the Pall ring of one group of metal, and the inserts of other packing layer is Taylor's garland of one group of metal.
Tower body is also provided with one group of access hole, access hole respectively with corresponding spray district corresponding matching.
Described tower body lower end is conical funnel structure, is provided with outlet of sewer in the bottom of funnel structure.
The tower body told is cylindrical shape, the conical outlet of sewer bottom tower body, and the product produced after gas, liquid can be facilitated to react landing on the tower wall tilted is got rid of from outlet of sewer again.
Plated film tail gas passes into after in tower body from air inlet, under the effect of air distribution plate, plated film tail gas mean allocation is risen, make spray district above can with plated film tail gas uniform contact.
This device is provided with three spray districts, and two spray plot structures are below identical, and its packing layer adopts the absorption member of Taylor's garland of metal, is used for increasing the time of staying of liquid in tower further, thus increases the time of contact of gas-liquid, improves purification efficiency.The packing layer in spray district of the superiors adopts the Pall ring of metal, and under gravity, the foam that gas liquid reaction is produced easily is adsorbed on Pall ring, reduces foam and rises with air-flow and take tower body out of.
Described access hole is arranged on the middle part in three spray districts, facilitates three to spray the cleaning of district's packing layer and the maintenance of replacing and shower.
The invention has the advantages that: this device stability can be high, simple to operate, safe and reliable, easy to maintenance, adopt the spray district of the different inserts of multilayer, better clean-up effect can be reached.
