Circular dosing and fumigating system and method

Abstract

The invention relates to a circular dosing and fumigating system and method.. The circular dosing and fumigating system comprises two fumigating chambers; the fumigating chamber A is connected with a fumigating chamber B through two parallel pipelines; a dosing pipeline is connected through a parallel-connection pipeline A, and a fumigation agent recovery device is connected through a parallel-connection pipeline B; the amount of a fumigation agent is set by a program of a PLC (Programmable Logic Controller); the weight of the fumigation agent is collected by a weight sensor; the concentration of the fumigation agent is collected by a fumigation agent detector; and states of each solenoid valve and each pipeline air blower in a system pipeline are controlled by the PLC, so that the fumigation agent is circularly dosed and used between two fumigating chambers in a sealed fumigating system, and therefore the emission reduction of the fumigation agent can be realized, and the circular utilization of the residual fumigation agent can be further sufficiently used. Meanwhile, the circular dosing and fumigating system has no damage on humans and animals and no pollution to an environment. The circular dosing and fumigating system has regulation and control capability through automatic control. By utilizing the circular dosing and fumigating system, the concentration can be dynamically adjusted according to the using condition of the fumigation agent, so that the current situation that the conventional fumigating system causes environmental pollution is changed.

Description

technical field [0001] The invention relates to inspection and quarantine fumigation treatment facilities, in particular to a system and method for circulating medicine pouring fumigation. Background technique [0002] In recent years, with the economic development of our country, domestic and foreign trade exchanges have become more and more frequent, and various harmful organisms such as insects, germs, weeds, etc. have been introduced into and out of our country with the goods, causing huge damage to our country's ecological environment security and agricultural and forestry production. threaten. In order to ensure that foreign harmful organisms are not introduced into our country and at the same time promote the export of agricultural products in our country, inspection and quarantine agencies implement strict inspections on inbound and outbound goods, and carry out quarantine treatment on goods carrying foreign harmful organisms, such as using physical or chemical treat...

AI Technical Summary

Problems solved by technology

Tents are used as fumigation warehouses, and containers are also used as fumigation warehouses. In short, the existing fumigation treatment facilities are relatively simple, and most of the fumigants are manually controlled. Fumigants are poisonous to humans and animals and pollute the environment. It is very necessary to reduce emissions

[0005] How to design a reusable fumigant and a high degree of automation circulation fumigation fumigation system, so that it can realize the reduction of fumigant emissions, and make full use of the remaining fumigant to continue to use, while not causing harm to humans and animals Harm, no pollution to the environment, has become one of the research topics for those skilled in the art. At present, there is no such technology reported in the literature in China
