After grain, the waste liquid circulation valve of water leg is closed；Water leg lower part outlet valve is opened, the sewage in water leg is poured into measuring tank
Weighed, then opening the outlet valve of measuring tank makes liquid batch be transferred in blender, control single enters in blender
Sewage quantity is 95~105L；
Step 3.2 opens cement bin bottom shutter valve, cement is entered blender, and cement is controlled by star-like feeder
Load is 70~80 kilograms；The agitating device of blender is opened, sewage and cement is mixed in blender, forms dirty
Water cement mixture；The slide valve of blender bottom is opened, the sewage cement admixture after stirring is injected in pail for used dressings；
Step 3.3 is stood, and initial set is no less than 24 hours, then ultimately forms qualified solidified cement body through the maintenance of excessive day.
The tail gas produced in the drying course of the step 2.2 initially enters condensate cooler 6 and cooled down, and condensate liquid is certainly
Flow into water leg；The tail gas of residual merges with the tail gas that blender is produced after condensed, and gas-solid is carried out into cyclone separator 7
Separation, the radioactive grain carried secretly in gas is separated, and the solid particle after separation directly passes through the valve of slagging tap of cyclone separator 7
Into ash collection slot, the gas after separation enters high efficiency particulate air filter, and after radionuclide therein is adsorbed, residual gas passes through
Centrifugal blower is discharged into air.
The centrifugal blower maintains to be 0.03~0.06Mpa in whole system.
It is provided with the step 1.2 on head tank from discharge orifice, when every batch of feeding is excessive, unnecessary mud auto-returned water
In pond or basin.
The sewage quantity for controlling single to enter in blender in the step 3.1 is 100L.
The load of cement is controlled to be 75 kilograms by star-like feeder in the step 3.2.
It is 1m that mud speed rate is controlled when being conveyed in the step 1.23/h。
Horizontal screw centrifugal filter rotating speed is 3000rad/min in the step 2.1.
The mud drying and processing ability of dryer is 150kg/h in the step 2.2.
The beneficial effect of patent concordance prior art of the present invention is：(1) whole process takes long-distance remote control control, fully protects
The irradiation safety and industry security of personnel during card waste time takes；(2) device miniaturization and it ensure that the features such as be easy to decontamination
This complete equipment reusable reduces waste processing cost in other similar engineerings；(3) waste packaging physical efficiency after reorganizing and outfit directly with
Existing waste processing, disposal facility interface, effectively reduce secondary required human and material resources, the financial resources reorganized and outfit of waste and put into.
