Description
Technical field
The present invention relates to the processing units and processing method of a kind of inorganization emptying exhaust gas.
Background technology
Inorganization drain is relatively more in methane chloride refining plant, there is the drain of 20 or so, setting originally
Meter is all to drop a hint after condensed device condenses live to be vented, and refrigerant is that dichloromethane is cooled to 5 DEG C by F22 used for refrigerator, so
Low temperature dichloromethane is sent to each condenser afterwards, since in operation, low temperature refrigerant systemic breakdown, condenser deactivates for a long time
After damage so that organic matter increases in discharge gas, while it is big to restore cryogenic system investment.
Invention content
The present invention provides the processing units and processing method of a kind of inorganization emptying exhaust gas, it uses direct condensation,
Direct deep cooling receives material, improves efficiency.
Present invention employs following technical schemes：A kind of processing unit of inorganization emptying exhaust gas, it is vented including high pressure
Manifold, lp venting manifold, surge tank I, surge tank II and caustic wash tower, the high pressure emptying output terminal of manifold and lp venting manifold
Output terminal be connected by wind turbine I with the import of surge tank I, the outlet of surge tank I by condenser I and surge tank II into
Mouth is connected, and the outlet of surge tank II is connected with the import of caustic wash tower, and the outlet of caustic wash tower passes through wind turbine II and activated carbon is inhaled
Attached tank is connected.
The condenser I is set as F22 refrigeration machines, on F22 refrigeration machines by be connected with gas phase F22 return mechanisms with
Caustic wash tower is connected.
The bottom of the surge tank I is connected with circulating pump I and return mechanism in turn.
The alkali cleaning tower bottom is connected with alkali slot, and alkali cleaning tower bottom is connected with the import of alkali slot, and the outlet of alkali slot leads to
Circulating pump II is crossed with the top of caustic wash tower to be connected.
The invention discloses a kind of processing methods of inorganization emptying exhaust gas, it includes the following steps：First by inorganization
Exhaust gas is vented, exhaust gas divides high pressure to be vented manifold and lp venting manifold progress categorised collections by high pressure with low pressure, then passes through
The negative pressure centralized collection that wind turbine I generates directly is condensed to surge tank I and then using F22 refrigeration machines, is collected the material to get off and is passed through
F22 return mechanism fixed gases are sent to caustic wash tower neutralization, are vented after wind turbine II and absorbent charcoal adsorption tank absorption.
The invention has the advantages that：After employing above technical scheme, the present invention is by amorphous discharge
Emptying end gas be collected, condense, separating treatment, so as to recycle material in exhaust gas, and reduce the pollution to environment.This hair
Bright concentration exhaust-gas treatment, and only with a condenser, equipment investment is few.Recovery and treatment method of the present invention uses combined method, deep cooling
It is combined with absorption, ensures that content of organics is less than 50PPM in the fixed gas of emptying.
