Afterwards, temperature can be fallen after rise from 360 DEG C to 310 DEG C, be then shut off the combustion of natural gas of combustion chamber, the indoor slag natural cooling of thermal desorption
When to 180 DEG C, the water in rainwater collection pool is cooled down about 15min by water injecting pump dust suppression of spray water into thermal desorption room at this time, is sprayed water
Amount control does not play fugitive dust when residue is come out of the stove without waste water water clock yet, and the moisture content for the residue that discharges is 15%.When residue temperature is lower than
At 100 DEG C, thermal desorption room is opened, is scraped residue into chain transfer hopper using scraping blade, residue is delivered to residual by chain transfer hopper
Storage in slag bath, residue moisture content about 15% are in mud cake shape, are packed into transfer hopper, and transfer hopper is conveyed residue using chain mode
To residue pool.Successively desorption forms resolution gas out from greasy filth for water and petroleum hydrocarbon（Petroleum hydrocarbon+vapor）It is drawn into resolution gas
In condenser system, cooled down indirectly using water.The liquid oil water mixture to cool down（Oil quality accounting about 80%, water accounting is about
20%）Enter oil water separator by pipeline, the oil of separation is stored using pipeline to the diesel oil tank of visualization laying；Point
From water enter cesspool, enter back into greasy filth pond, after being mixed with oil base landwaste, into thermal desorption room in handled again.Through
Cross the fixed gas after condenser system in pipeline（Predominantly C4 petroleum hydrocarbon below, based on methane）It is removed by alkaline process spray column
HCL, the lower vapor of condensation etc. in fixed gas, then it is delivered to combustion chambers burn processing.At oil-base mud and oil patch thermal desorption
The residue obtained after reason forms thermal desorption product by dehydration, and the diesel oil generated is added in thermal desorption treatment process and is sent
Configuration oil base drilling fluid is recycled to shale gas drilling platforms.
The thermal desorption product that S4, oil-base mud and oil patch are formed after thermal desorption is handled, is stored in storage first
