It is suitble to intermittently operated；Condensation method critical component is refrigeration compressor, the characteristics of condensation method technique be it is concise directly, be not required to secondary working
Skill processing, recycling product are without secondary pollution.But it is limited by refrigerant, refrigerant and energy consumption, the condensation temperature of refrigeration compressor has
Limit (- 40 DEG C~-70 DEG C of general condensation temperature), cannot will volatilize completely oil gas liquefaction, tail gas cannot reach discharge standard (≤
25g/m3).
Liquid nitrogen is a kind of multifunction refrigeration agent/refrigerant, have it is nontoxic, non-corrosive and nonflammable, can achieve-
196 DEG C of normal boiling point.
To solve refrigeration compressor condensing refrigerant amount deficiency, the problem that the VOC rate of recovery is low, exhaust emissions is not up to standard, this hair
Bright proposition is recycled vaporizing oil-gas using liquid nitrogen cryogenics condensation method, improves the VOC rate of recovery, to reach dirty to environment zero
Contaminate purpose.
Summary of the invention
It is an object of the invention to provide a kind of liquid nitrogen cryogenics condensation VOC recovery processing work to solve prior art deficiency
Skill.
Main technical schemes of the invention are:
A kind of liquid nitrogen cryogenics condensation VOC recycling and processing device, including liquid nitrogen storage tank, cold incubator, booster fan, gas-liquid separation
The bottom discharge port of device and output pump, the liquid nitrogen storage tank is connect by pipeline with the cooling tube import of cold incubator, cold guarantor
The cooling tube outlet connection nitrogen of incubator goes nitrogen seal system；Vaporizing oil-gas pipeline connects the oil of cold incubator by booster fan
Tracheal entrance, the Oil/Gas Pipe outlet connection gas-liquid separator of cold incubator, the gaseous phase outlet emptying of gas-liquid separator, liquid-phase outlet
Head tank is connected by output pump.
The cold incubator includes heat exchanger, condenser, oil-gas pipeline and cooling line, and oil-gas pipeline is sequentially connected one
Grade heat exchanger, pipe separator, secondary condenser, pipe separator, three-level condenser, cooling line are sequentially connected three-level condensation
Device, pipe separator, secondary condenser, pipe separator, first-class heat exchanger.
A plurality of pipe device device in parallel in the cold incubator.
The step are as follows:
1) vaporizing oil-gas enters cold incubator after booster fan is pressurized and exchanges heat, and condensed lime set passes through pipeline point
It is recycled from device and gas-liquid separator, fixed gas emptying；
2) nitrogen evaporated after exchanging heat seals gas source as nitrogen, carries out nitrogen envelope, cooling for oil gas storage tank.
Heat-exchanging process first passes around first-class heat exchanger in the step 1), will volatilize the water vapour condensation abjection in gas,
The Volatile Gas of abjection water vapour enters secondary condenser swap-in row heat exchange, if Volatile Gas is not up to standard after secondary condenser heat exchange,
It automatically opens condenser three times and carries out heat exchange.
Secondary condenser design temperature is -40 degree in the step 1), and three-level design of condenser temperature is -110
~-185 degree.
Liquid nitrogen cryogenics condense VOC and are recycled technology, and since liquid nitrogen cooling capacity is very high, the VOC rate of recovery is arranged up to 99.999%
It deflates and can reach the zero-emission of organic matter, reduce volatile organic compounds and ozone depleting substances is discharged into the number in environment
Amount, recycling is thorough, (such as without waste water, nitrogenfree oxide, no acidic gas, no dioxin) without secondary pollution, recovery product quality
Height, and since the quantity of transmission parts is few, mostly static equipment, good reliability, simultaneously because liquid nitrogen price is lower, operation cost
Low (being calculated with the treatment scale of 100m3/h gas, liquid nitrogen consumption is only 0.14t/h), without cleaning, intermittently operated flexibility
By force, sledge installing meter and batch machining may be implemented, installation, management cost are low.
