2. the V-type of junior's spraying box, which flows backwards slot and spray head collocation, can more preferably settle acidic materials, compared to common acid mist
Absorption tower it is more efficient；
3. multiple stage circulation spraying box can effective filter acid gases, guarantee that discharge gas meets national standard.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.
Specific embodiment:
Refering to Figure 1, being the structural schematic diagram of the preferred embodiment for the utility model, the utility model is one kind
The waste heat transmission device that roasting acidification is separated with travel fatigue, mainly there is roaster 1, waste heat utilization equipment 2, the row of the roaster 1
Port acts on 2 outer surface of waste heat utilization equipment after cyclone separator 7, then is discharged via second level acid gas separation equipment.Its
In, second level acid gas separation equipment includes the higher level's spraying box 3 and junior's spraying box 4 of vertical connection setting, higher level's spraying box 3
In be equipped with the first spray head 30 and netted alkaline absorbed layer 31, odor-absorbing layer 32, the second spray is equipped in junior's spraying box 4
First 40 and several V-types flow backwards slot 41, each V-type is divided into gas communication port between flowing backwards between slot 41, and the second spray head 40 is corresponding
It is set to above each gas communication port.Gas first passes through junior's spraying box 4, in V-type after waste heat utilization equipment 2 consumes thermal energy
Flow backwards and effectively settled under slot 41 and the cooperation of the second spray head 40, gas communication port of the sour water between V-type refluence slot 41 to
It flows down, gas goes successively to be discharged after neutralizing and de-taste in higher level's spraying box 3, and the sour water formed after filtering is then by junior
Sour water collecting pit 8 is equipped with below spraying box 4 to be collected.
There is exhaust pipe 5, exhaust pipe 5 is equipped with triple valve 50, triple valve 50 and exhaust above the gas outlet of higher level's spraying box 3
Gas detection meter 51 is equipped between pipe 5, and in the air inlet for connecting the connection junior's spraying box 4 of return pipe 6 on triple valve 50, discharge
Gas comply with standard then normal discharge through the detection of gas detection meter 51, if detection is unqualified, triple valve 50 is introduced a gas into
Return pipe 6 makes unqualified gas reenter junior's spraying box 4 and carries out circulating filtration.
2 outer surface of waste heat utilization equipment is equipped with hot gas path 21, and hot gas path 21 is sprayed by communicating pipe 20 and junior
