It is middle by direct emission, be in atmosphere bromomethane most directly and most important source.In order to reduce bromomethane discharge, atmosphere is protected
Ozone layer, countries in the world are generally adsorbed the bromomethane after stifling using active carbon or other adsorbent materials, are avoided
Bromomethane direct emission is entered into atmosphere.
For adsorbent materials such as the active carbons that has adsorbed bromomethane, can take it is buried, burn or the parents such as sodium thiosulfate
The technologies such as nuclear chemistry reagent immersion, degrade.But there are timeliness, safety and secondary pollution problems, examples for degradation technique
It is usually required 5 to 10 years or more as buried, burns and chemical reagent immersion can generate gas or liquid debris etc..With bromine
The price of methane persistently increases, and industry exploration carries out concentration desorption to the adsorbent material for having adsorbed bromomethane, to desorbing
The higher bromomethane of purity liquefied after, then reused.
Currently, the liquefied method of bromomethane has directly condensation, pressurized liquefied and pressurization condensation etc..It is comprehensively compared, pressurizes cold
The efficiency highest of solidifying method only needs 2 atmospheric pressure that can carry out efficient liquefaction to methyl bromide gas at 4 deg. celsius, and then realizes
Recycling and reusing.But economically viable recycling and reusing system is also lacked at present.
Utility model content
The main purpose of the utility model is that developing the economically viable bromomethane liquefaction for desorption of one kind and benefit again
Recycling and reusing system.The device can carry out efficient liquefaction to methyl bromide gas, efficiently separate vapor therein, and
The bromomethane after liquefaction is easily transferred to bomb storage transport or is directly launched into new stifling facility, to realize bromine
Methane recovery recycles.
Realize the utility model aim technical solution are as follows:
A kind of bromomethane recycling and reusing system, including bromomethane adsorbent material container, liquefied pot, the bromomethane absorption
Containers connect the liquefied pot by pipeline, and the liquefied pot is connected with water chiller and air compressor machine;The liquefied pot
Tank body is pressure-resistant tank body, and tank body is coated with insulating layer;Liquefaction pot bottom is connected with collecting tank.
