Gas skewness, reduces the utilization rate of activated coke in tower, while decreases the treating capacity of flue gas, and easily produces in tower
Topically active is burnt excessive with smoke contacts, and reaction heat is big, causes the rapid phenomenon of Ta Nei local temperature rises, adds activated coke and catch fire
Risk.
The content of the invention
The purpose of this utility model is to solve defect existing in the prior art, there is provided one kind can be effectively increased in tower
The column for smoke purification of active coke utilization.
In order to achieve the above object, the utility model provides a kind of column for smoke purification, including active coke desulphurizing tower, activity
Burnt denitrating tower or active coke desulphurizing denitrating tower；The middle part tower body of the column for smoke purification is the cavity knot surrounded by least three sides
Structure, lower end are equipped with smoke inlet flue, and upper end is equipped with exhanst gas outlet flue；The utility model column for smoke purification tower body one of them
The upper end of side is equipped with above-mentioned exhanst gas outlet flue, and the lower end of other sides is respectively equipped with above-mentioned smoke inlet flue.Using more
A smoke inlet flue, is conducive to flue gas and is evenly distributed in tower.
Further, column for smoke purification tower body is to surround cuboid cavity structure by four sides；Wherein, smoke inlet cigarette
Road is three, is respectively arranged on the lower end of wherein three sides；Exhanst gas outlet flue is arranged on the upper end of remaining side.
Further, column for smoke purification further includes header；Smoke inlet flue is provided with the outside of column for smoke purification tower body
Header is respectively equipped with each side, and the outside lower end of each header is connected with corresponding smoke inlet flue respectively, inner side with
The inside of column for smoke purification tower body is connected.Designed by the header between in smoke inlet flue to tower body, by header to entering
Mouthful flue gas enters in tower just now after being pre-mixed, and furthermore achieved that being uniformly distributed for flue gas in tower.
Further, the end face that header is connected one end with column for smoke purification tower body is AND DEWATERING FOR ORIFICE STRUCTURE.Pass through AND DEWATERING FOR ORIFICE STRUCTURE
Design so that enter in tower flue gas uniform vertical.
Further, header is cuboid, the center position positioned at the column for smoke purification tower body side, with the side
The end face size of junction is 3/4-1 times of the lateralarea.
Further, the aperture size of the AND DEWATERING FOR ORIFICE STRUCTURE of the AND DEWATERING FOR ORIFICE STRUCTURE of header is slightly less than activated coke particle diameter, and pitch-row is work
2-3 times of property char particle footpath.
Further, it is respectively equipped with gas baffle at smoke inlet flue and exhanst gas outlet flue.
The utility model has the following advantages compared with prior art：
(1) flue gas is entered in tower body by three tunnels, is conducive to flue gas and is evenly distributed in tower, promotes the work at each position in tower
Property it is burnt fully reacted with flue gas, improve the utilization rate of activated coke, increase the treating capacity of flue gas, improve the effect of desulphurization denitration
Fruit；Topically active Jiao and excessive smoke contacts in tower have also been extenuated at the same time, and are caused heat of reaction big and can not be passed in the short time
Lost, the occurrence of Ta Nei local temperature rises are rapid is passed, reduces the risk that activated coke is caught fire.
（2）By adjusting the aperture of three road smoke inlet flue upper flue baffle of tower body, each road gas approach is changed
Exhaust gas volumn, can further optimize uniformly distributed situation of the flue gas in tower.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model column for smoke purification.
In figure, 1- tower bodies, 2- gas baffles, 3- smoke inlet flues, 4- exhanst gas outlet flues, 5- headers.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model column for smoke purification is on the basis of existing desulfurizing tower, denitrating tower or desulphurization denitration tower
On be improved.Form the header 5 that flat rectangular parallelepiped structure is respectively equipped with three sides of tower body 1.Header 5 and tower body 1
The side of connection uses AND DEWATERING FOR ORIFICE STRUCTURE, and the aperture size of AND DEWATERING FOR ORIFICE STRUCTURE is slightly less than activated coke particle diameter, and pitch-row is activated coke particle diameter
2-3 times., which is equipped with smoke inlet flue 3, gas baffle 2 is arranged on each smoke inlet flue 3.
One side of residue upper end of composition tower body 2 is equipped with exhanst gas outlet flue 4, and gas baffle 2 is also provided with exhanst gas outlet flue 4.
