Whole system is under micro-vacuum state, the pressure in revolution speed control system by adjusting frequency conversion fan.Having after processing
Machine waste gas enters chimney qualified discharge by air-introduced machine.
The course of work and principle of the present utility model are as follows：
First, waste gas purification apparatus and air-introduced machine are opened, ensures that the closed greenhouse of steel construction is in the state of tiny structure.So
Afterwards, organic polluted soil is handled by sieving approach equipment, meet particle diameter (≤:25mm) desired soil enters in material bin, enters
Enter the elevating hopper that the soil to hopper is sent to agitating device by measuring conveyer, upper doses is set by measuring conveyer
Put, realize automatic ration be fed, contaminated soil enter agitating device elevating hopper when, powder drug dosing device simultaneously up
The quantitative automatic dosing of hopper.Treat contaminated soil and after the completion of powder medicament all fills, agitating device agitating shaft starts to rotate, feeding
Struggle against and start lifting feeding, after the completion of feeding, water-adding system is initially added into the water set, and progress liquid adds after the completion of adding water
Medicine system is initially added into the liquid pharmaceutical of set amount, and after the completion of liquid pharmaceutical dosing, stirring goes out after reaching the time set
Material, the soil after processing enter soil after dumper is transported to processing by discharging opening and store up area.After the completion of above-mentioned feeding
While subsequently add water conservancy project sequence, metering conveyer has started work next time.Continuous production operation is formed with this.
In processing procedure, in the closed greenhouse of steel construction caused organic exhaust gas by pipeline sequentially enter UV photodissociation waste gas treatment equipment and
Active carbon adsorption equipment purified treatment, enter chimney qualified discharge finally by air-introduced machine.
In whole processing procedure, all devices are all to realize remote auto control by PLC control system, largely
On reduce crew numbers and working time in the present context, very big guarantor has been obtained to the health and safety of staff
