Abstract
The invention relates to a washing tower used for treating low-radiation coating exhaust. The washing tower comprises a tower body (1) , wherein an air outlet (4) is formed in the upper end of the tower body, and a sewage outlet (6) is formed in the lower end of the tower body; an air inlet (3) is further formed in a side wall of the lower end of the tower body; the tower body is connected with a lye source (2) through a spraying pipe (5) and the washing tower is characterized in that a group of sprinkling areas (11) are arranged inside the tower body; the sprinkling areas (11) are arranged above the air inlet (3); an air distribution board (8) is connected in a matched manner inside the tower body and arranged between a bottom spraying area and the air inlet. The washing tower provided by the invention has the following advantages: the washing tower is high in stability, simple to operate, safe, reliable and convenient to maintain; besides, due to the adoption of multilayered sprinkling areas with different fillers, a better purifying effect is achieved.
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 further worsens, and environmental problem has become 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.Comparatively complicated acidic materials and the larger dust of containing of the high-temp waste gas composition that low radiation on-line coating produces, and in lessivation, there is foam to produce, if directly discharge, to environment be caused to very serious pollution, therefore, before discharging waste gas, must carry out purified treatment, make flue gas obtain effectively cooling and purification, and then discharge, be conducive to the sustainable development of environment.This just require on-line coating tail gas clean-up with 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 comparatively desirable technical scheme.
Summary of the invention
The object of the invention is to process high temperature, acidity, dust-laden and the inefficient shortcoming of plated film waste gas such as fluorine-containing in order to solve present stage existing scrubbing tower, and a kind of scrubbing tower for the treatment of low-emission coated tail gas proposing.。
To achieve these goals, the present invention has adopted following technical scheme:
A scrubbing tower for the treatment of low-emission coated tail gas, comprises tower body, is provided with gas outlet, lower end is provided with outlet of sewer, is also provided with air inlet on the sidewall of tower body lower end in the upper end of tower body, and tower body connects alkali lye source by shower, it is characterized in that:
A, in tower body, be provided with successively one group of spray district, 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, is provided with the opening corresponding with packing layer on shower;
B, the air distribution plate that is also connected in tower body, 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, can there is following further technical scheme:
Described packing layer comprises the string bag, is provided with inserts in the string bag, 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.
On tower body, be 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, in the bottom of funnel structure, is provided with outlet of sewer.
The tower body of telling is cylindrical shape, and the conical outlet of sewer of tower body bottom can facilitate the product landing on the tower wall tilting producing after gas, liquid reaction from outlet of sewer, to get rid of again.
Plated film tail gas in air inlet passes into tower body, 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 even contact.
This device is provided with three spray districts, and two spray plot structures are below identical, and its packing layer adopts the water suction member of Taylor's garland of metal, is used for further increasing the time of staying of liquid in tower, thereby increases the time of contact of gas-liquid, improves purification efficiency.The packing layer in the superiors' spray district adopts the Pall ring of metal, and under the effect of gravity, the foam that gas liquid reaction is produced is easily adsorbed on Pall ring, reduces foam and rises and take tower body out of with air-flow.
Described access hole is arranged on the middle part in three spray districts, facilitates the cleaning of three spray district packing layers 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, can reach better clean-up effect.
