During apparatus of the present invention work, the mobile disinfecting car 6 that is loaded with seal closure 2 is reached near the freight container 1 of customs supervision, utilize the hanging device 9 on mobile disinfecting car 6 that seal closure 2 is arranged on freight container 1.Concrete operations are: the door 102 of freight container 1 is opened and reserved crack between a door and its frame 103, utilize during hanging device 9 lifting and be located at forked union joint 901 use the bolts 902 of arm front end and coordinate and carry seal closure 2 with hanger 202 on seal closure 2, coordinate seal closure 2 is fixed on the doorframe of freight container 1 with the hinge 101 of freight container 1 by the clamp 204 on seal closure 2, utilize silicone rubber O-ring 203 sealings that 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 actuators 5 to sending into ethylene oxide gas in pressure storehouse 6 and freight container 1, purifying air and heat is provided by automatic control system 8, and extraction contains the waste gas of oxirane, utilize waste gas combination apparatus 17 to carry out chemical combination and collect, then concentrate degradation treatment.After sterilization is completed, seal closure 2 is unloaded and piles up on mobile disinfecting car 8 from freight container 1, supported by support 801 after hanging device 9 draws in.
During sterilization, the first electromagnetic valve 12f opens, after gasifying, the gasifier 13 that ethylene oxide gas is heated via hot water apparatus by oxirane steel cylinder 10 enters pressure storehouse 6, enter in seal closure 2 by the 7th electromagnetic valve 12e and silicone rubber sterilizing tube 3, ethylene oxide gas is sent in freight container 1 and is carried out disinfection from crack between a door and its frame 103 again.When ethylene oxide concentration sensor D measures the interior oxirane in pressure storehouse 6 still higher than after setting concentration value, the first electromagnetic valve 12f closes, and oxirane steel cylinder 10 stops air feed.The effect of heater 19 is to make the ethylene oxide gas in pressure storehouse 6 keep the temperature of setting by radiator.After predetermined disinfecting time finishes, the first electromagnetic valve 12f closes, the 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 carry out chemical combination degraded and residual air adsorption treatment through pressure storehouse 6, at this moment the 3rd electromagnetic valve 12d, the 5th electromagnetic valve 12g are in closed condition; Bleed and make air pressure in pressure storehouse 6 to 0.5Kg/cm when lobe pump 16
2The time, the 4th electromagnetic valve 12b closes, and the 3rd electromagnetic valve 12d, the 5th electromagnetic valve 12g open, and by air purifier 15, to pressure storehouse 6, are sent into and purify air to equalizing pressure; Pressure transducer C measures the 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 that the pulsation circulation extracts ethylene oxide gas out.Heater and damping device, according to the signal controlling operation that temperature sensor A and humidity sensor B detect, keep pressure storehouse 6 to be in the duty of setting by automatic control system 7.
The waste gas that contains oxirane enters each reactor 1722,1711 waste gas combination apparatus 17 from air inlet pipe 1702,1707, carry out first set reaction by air filter cover 1705, collecting and distributing box 1717 with the concentrated sulphuric acid in reactor 1722,1711, after reaction, generating glycol will take out collection after reacting full closing, and as industrial chemicals, further utilize; The residual air that reaction produces, need further chemical combination to resolve because containing ethylene oxide gas; Residual air continue to arrive allotter 1716 via decentralized network 1718 to the dispersed secondary response that carries out of concentrated sulphuric acid dielectric solvent in combination apparatus, reaction generates the higher ethylene glycol sulfonated bodies of cement coefficient, is sepia; Residual air after secondary response enters composite filter gas tank 1710 by exhaustor 1712, becomes innocuous gas after each filter adsorption filtration, then by delivery pipe 1708, to place, discharges; In the time of waste gas combination apparatus 17 work, inject the circulating water that can dispel the heat by water inlet pipe 1701 and drain pipe 1713 to the closed box 1720 of combination apparatus, in order to reduce each reactor 1722,1711 heats that produce when carrying out chemical reaction.
Apparatus of the present invention can be carried out sterilization to a plurality of freight containers simultaneously, process the ethylene glycol of oxirane and strong sulfuric acid response generation for the waste gas combination apparatus, after the combination apparatus reaction is saturated, can take out as the raw material of industry and use again, oxirane waste gas for the absorption of composite filter gas tank, can adopt secondary reflection stove combustion method to process, product is carbon monoxide and a small amount of steam, to environment without harm.
