Feed channel, the external flue gas leading of inlet end of admission line, the outlet side of admission line are located at the inside of tower body, and admission line goes out
Air distribution plate is arranged in gas end, and spray tube is arranged in the upper end inside tower body, and multiple spray heads, one end setting of tower body are arranged on spray tube
Oil separator, oil separator are connected with tower body, polylith oil separating plate are arranged in oil separator, the bottom of oil separating plate is provided with limbers, oil removal
Water return outlet is arranged in the lower part in pond, and water return outlet is connected with spray tube, and drain tap is arranged in the upper end of oil separator, is arranged on drain tap and lets out
Fuel tap.
Preferably, the air distribution plate is circular ring type sector air distribution plate, and circular ring type sector air distribution plate is made of polylith rhombic plate,
Spacing fixed setting between rhombic plate, the angle being spaced between rhombic plate and horizontal plane are 5-15 degree.
Preferably, the spacing between oil separating plate is fixed, and the height of oil separating plate increases successively from left to right, highest oil separating plate with
Oil storage unit is used as between the pool wall of oil separator.
Preferably, cover board is arranged in the upper end of oil separator, and cover board is hinged with oil separator by hinge.
Compared with prior art, the utility model has the advantages that：
The air distribution plate of the utility model can uniformly disperse exhaust gas, increase the stop in tower body of oil smoke
Time, spraying cooling deoiling effect is good, and flow can also reuse, and can periodically be collected back according to the case where greasy dirt
It receives, promotion and application have a extensive future, and exhaust gas concentration of emission is far below limited value of discharge standard, and waste gas purification effect can reach ring
Guaranteed request.

Specific implementation mode
The utility model embodiment is described further below in conjunction with the accompanying drawings：
Embodiment 1
As shown in Figure 1, outlet is arranged in reverse-flow atomization spray tower described in the utility model, including tower body, the upper end of tower body
Admission line 2, the external flue gas leading of inlet end of admission line 2, the outlet side of admission line 2 is arranged in the side of port 11, tower body
Positioned at the inside of tower body, air distribution plate 3 is arranged in the outlet side of admission line 2, and the air distribution plate 3 is circular ring type sector air distribution plate, circle
Ring type sector air distribution plate is made of polylith rhombic plate, and the spacing fixed setting between rhombic plate could be provided as 280mm, diamond shape
The angle being spaced between plate and horizontal plane is 5-15 degree, and it is evenly dispersed that this structure can be such that air-flow maximizes, and increase exhaust gas and exist
Residence time in tower body, spraying cooling deoiling effect is good, and spray tube 1 is arranged in the upper end inside tower body, and setting is more on spray tube 1
Oil separator 4 is arranged in one end of a spray head 10, tower body, and oil separator 4 is connected with tower body, is specifically connected by pipeline, every
