During apparatus of the present invention work, near the freight container 1 mobile disinfecting car 6 being loaded with seal closure 2 being reached customs supervision, the hanging device 9 on mobile disinfecting car 6 is utilized to be arranged on freight container 1 by seal closure 2.Concrete operations are: opened by the door 102 of freight container 1 and reserve crack between a door and its frame 103, utilize forked union joint 901 bolt 902 being located at arm front end to coordinate with the hanger 202 on seal closure 2 when hanging device 9 lifts and carry seal closure 2, being coordinated with the hinge 101 of freight container 1 by the clamp 204 on seal closure 2 is fixed on the doorframe of freight container 1 by seal closure 2, utilize silicone rubber O-ring 203 to seal and freight container 1 is formed closed space body, then silicone rubber sterilizing tube 3 is connected on the pipe joint 201 of seal closure 2; Control actuator 5 by automatic control system 8 to send into ethylene oxide gas, purify air and heat is provided in Pressure chamber 6 and freight container 1, and the waste gas extracted containing oxirane, utilize waste gas combination apparatus 17 to carry out chemical combination collection, then concentrate degradation treatment.After having sterilized, unloaded by seal closure 2 pile up on mobile disinfecting car 8 from freight container 1, hanging device 9 is supported by support 801 after drawing in.
During sterilization, first electromagnetic valve 12f opens, ethylene oxide gas enters Pressure chamber 6 after being gasified via the gasifier 13 that hot water apparatus heats by oxirane steel cylinder 10, enter in seal closure 2 by the 7th electromagnetic valve 12e and silicone rubber sterilizing tube 3 again, ethylene oxide gas is sent in freight container 1 from crack between a door and its frame 103 and is carried out disinfection.When ethylene oxide concentration sensor D to measure in Pressure chamber 6 oxirane still higher than setting concentration value after, the first electromagnetic valve 12f closes, and oxirane steel cylinder 10 stops air feed.The effect of heater 19 makes the ethylene oxide gas in Pressure chamber 6 keep the temperature of setting by radiator.After predetermined disinfecting time terminates, first electromagnetic valve 12f closes, second electromagnetic valve 12a, the 4th electromagnetic valve 12b open, lobe pump 16 starts to bleed, oxirane waste gas in freight container 1 is delivered to waste gas combination apparatus 17 through Pressure chamber 6 and carries out chemical combination degraded and residual air adsorption treatment, at this moment the 3rd electromagnetic valve 12d, the 5th electromagnetic valve 12g are in closed condition; Bleeding when lobe pump 16 makes air pressure in Pressure chamber 6 to 0.5Kg/cm
2time, the 4th electromagnetic valve 12b closes, and the 3rd electromagnetic valve 12d, the 5th electromagnetic valve 12g open, and purifies air to equalizing pressure by air purifier 15 to Pressure chamber 6 feeding; Pressure transducer C measures equalizing pressure parameter, and the 3rd electromagnetic valve 12d, the 5th electromagnetic valve 12g close, and the second electromagnetic valve 12a, the 4th electromagnetic valve 12b open, and the lobe pump 16 repetition said procedure that again starts to bleed realizes pulsating cyclic and extracts ethylene oxide gas out.The signal controlling run that heater and damping device are detected according to temperature sensor A and humidity sensor B by automatic control system 7, keeps Pressure chamber 6 to be in the duty of setting.
Waste gas containing oxirane enters each reactor 1722,1711 waste gas combination apparatus 17 from air inlet pipe 1702,1707, first set reaction is carried out with the concentrated sulphuric acid in reactor 1722,1711 by air filter cover 1705, collecting and distributing box 1717, after reaction, taking-up is collected by generating glycol after the full conjunction of reaction, utilizes further as industrial chemicals; The residual air that reaction produces, resolves because needing further chemical combination containing ethylene oxide gas; Residual air continues to arrive allotter 1716 and carries out secondary response via decentralized network 1718 to concentrated sulphuric acid dielectric solvent in combination apparatus is dispersed, and reaction generates the higher ethylene glycol sulfonated bodies of cement coefficient, in sepia; Residual air after secondary response enters composite filter gas tank 1710 by exhaustor 1712, after each filter adsorption filtration, become innocuous gas, is then discharged to place by delivery pipe 1708; While waste gas combination apparatus 17 works, inject the circulating water that can dispel the heat, in order to reduce the heat that each reactor 1722,1711 produces when carrying out chemical reaction by water inlet pipe 1701 and drain pipe 1713 to the closed box 1720 of combination apparatus.
Apparatus of the present invention can carry out sterilization to multiple freight container simultaneously, for the ethylene glycol that waste gas combination apparatus process oxirane and strong sulfuric acid response generate, after combination apparatus reaction is saturated, can take out and use again as the raw material of industry, for the oxirane waste gas of composite filter gas tank absorption, can adopt the process of secondary reflection stove combustion method, product is carbon monoxide and a small amount of steam, to environment without harm.
