Abstract
The invention relates to a photodegradation device of phosphine fumigation exhaust gas, which is characterized in that the photodegradation device comprises a shell (1), an ultraviolet light-emitting device (2) which is arranged in the shell and is used for degrading the phosphine fumigation exhaust gas, and a gas pipeline (3) which is made of a transparent material, arranged in the shell and is used for the phosphine fumigation exhaust gas to pass through. After fumigation and through gas flow guidance, the phosphine fumigation exhaust gas is introduced into the transparent gas pipeline (3) through a gas inlet (4) of the photodegradation device, and the phosphine is degraded under the action of the ultraviolet light generated by the ultraviolet light-emitting device (2) and then flows back into a fumigation closed environment through an outlet (5). Thus, the device is not needed to be opened to disperse gas after finishing the fumigation, so that the phosphine gas in the closed environment passes through the photodegradation device circularly to avoid the emission of harmful gas.
Description
Technical field
The present invention relates to a kind of phosphine fumigation exhaust gas light (ultraviolet light) decomposition apparatus, this device is mainly used in the degradation treatment of fumigation exhaust gas behind the phosphine fumigation, with replace in the past directly to the processing mode of airborne release toxic gas.
Background technology
Generally adopt phosphine fumigation to kill especially grain storage pest of reserve at present both at home and abroad, but the tail gas after stifling directly is discharged in the atmosphere.The material that can be in environment after hydrogen phosphide is discharged in the atmosphere be degraded to nonhazardous under the effect such as light.According to the literature, time of being degraded in environment of hydrogen phosphide needs 1 day approximately.In fumigation exhaust gas is discharged into short time in the environment, if contact the danger that still has murder by poisoning with people or higher mammal, current treatment measures and technology are that certain distance is set, and make the gas concentration of discharging in the storehouse obtain the abundant dilution of atmosphere with guarantee environment safety.Also there is document to propose to fumigate and adopts chemically treated method to solve toxic gas pollution, but lack practical application.
Summary of the invention
Purpose of the present invention utilizes hydrogen phosphide to be provided a kind of Photodegradation device of phosphine fumigation exhaust gas by the principle of ultraviolet degradation just at existing weak point in the above-mentioned prior art.This device can carry out light degradation through the photodissociation device with the tail gas after fumigating, and no longer directly discharges phosphine fumigation exhaust gas to atmosphere, but it is degraded to the material of nonhazardous, to reduce its pollution to environment.
Purpose of the present invention can realize by following technique measures:
Decomposition apparatus of the present invention comprises shell, the UV-light luminous device that is used for the phosphine fumigation exhaust gas degraded in the enclosure is set and be provided with in the enclosure be used for that employing light transmissive material that phosphine fumigation exhaust gas passes through is made gas piping.
Set gas piping is back-shaped structure setting among the present invention, also can adopt the mode of spiraling and being provided with, and purpose is to prolong as much as possible the time of contact of phosphine fumigation exhaust gas and ultraviolet light.
Operation principle of the present invention and beneficial effect are as follows:
Behind stifling the end, phosphine fumigation exhaust gas is introduced the gas piping of printing opacity through the air intake of Photodegradation device, phosphine fumigation exhaust gas flow back in the stifling environment through the gas outlet, and does not need with the diffusing gas that opens a position again after being degraded into the nonhazardous material under the effect of ultraviolet light.Because this device can carry out light degradation through the photodissociation device with the tail gas after fumigating, and no longer directly discharges phosphine fumigation exhaust gas to atmosphere, but it is degraded to the material of nonhazardous, to reduce its pollution to environment.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
The present invention is further described below with reference to embodiment (accompanying drawing):
Decomposition apparatus of the present invention comprises shell, 1 UV-light luminous device 2 is set in the enclosure and be provided with in the enclosure be used for that employing light transmissive material that phosphine fumigation exhaust gas passes through is made gas piping 3, and this gas piping 3 is with the back-shaped structure setting of bending coiling, cover top portion and bottom that the air intake 4 of described gas piping 3 and gas outlet 5 are provided with respectively.
Claims (1)
