Equipment for harmless processing of container sterilizing gas

Abstract

The invention discloses equipment for harmless processing of container sterilizing gas. The equipment comprises a magnetic attraction type gas suction device, a gas suction pipeline and a sterilizing gas harmless processing car. One end of the gas suction pipeline is connected with the magnetic attraction type gas suction device, and the other end of the gas suction pipeline is connected with the sterilizing gas harmless processing car. The sterilizing gas harmless processing car is a body device of the equipment. After the equipment is started, toxic gas sequentially passes through a first gas adsorption chamber, a second gas adsorption chamber and a third gas adsorption chamber in the sterilizing gas harmless processing car under the effect of a centrifugal fan to be harmlessly processed. The equipment has the main functions of harmlessly processing residual container sterilizing gas, reducing the pollution of toxic gas to air and water body and relieving the global greenhouse effect; by means of a gas suction type toxin dispersing mode, personal safety of site harmless processing personnel can be effectively guaranteed, toxin dispersing time can be greatly shortened, and the equipment has the advantages of shortening container retention time, increasing customs passing speed, reducing logistics cost for import and export enterprises and the like.

Description

technical field [0001] The invention relates to the field of pollution prevention and control of fumigation residual gas, more specifically, relates to the field of pollution prevention and control of residual fumigant gas in the sanitation and detoxification treatment of inbound and outbound containers and goods loaded in containers. Background technique [0002] Because fumigants such as methyl bromide, sulfuryl fluoride, and aluminum phosphide have the advantages of broad spectrum, strong permeability, and high lethality against harmful organisms, medical vector insects, and rodents carried by inbound and outbound cargo, they are widely used in inbound and outbound containers (cargo ) In terms of preventive sanitation and pest control, in 2015, the Shandong port alone implemented sanitation and pest control for 374,400 standard containers of entry. Taking a standard container that undergoes sanitation and detoxification treatment as an example, the current practice is bas...

Problems solved by technology

Taking a standard container that undergoes sanitation and detoxification treatment as an example, the current practice is basically to open the box to ventilate and disperse the poison after the fumigation is completed, and the ventilation and detoxification time is at least 12 hours. It takes a long time and consumes the time, manpower and logistics costs of import and export enterprises, and the total cost can reach more than 1,000 yuan; second, due to the influence of the physical and chemical properties of the fumigant itself, the process of unpacking and ventilating the poison may be caused by improper operation or long-term exposure. The gas poses a threat to the personal safety of those who open the box to release the poison; third, due to the environmental damage and high toxicity of the fumigant itself, such as methyl bromide has the chemical properties of destroying the ozone layer, and aluminum phosphide reacts violently with acid and water. When the temperature of phosphine gas exceeds 60°C, it will spontaneously ignite in the air or react with oxidants to cause combustion or explosion. In recent years, sulfuryl fluoride has been considered by scientists as a strong Efficient greenhouse gases remain in the air and water for a long time. Discharging these toxic gases directly into the external environment without treatment will undoubtedly aggravate environmental degradation and make the already overwhelmed natural and ecological environment worse.
