Problems solved by technology

However, due to the good airtightness of the container, there is the disadvantage that it is not easy to carry out quarantine and pest control, and it takes time and effort to move out and in the container, so the method of opening the door is generally used, and only slow-acting tablets can be used. Aluminum phosphide flakes (aluminum phosphide releases fumigant gas when it encounters air, usually fumigation takes 72 hours)
The disadvantages of this fumigation method are: the fumigation effect is not good, the time is long, the toxicity is high, and the poison is scattered slowly.
However, methyl bromide fumigation is highly toxic, causing danger to operators, and it is troublesome to carry a scale. Moreover, methyl bromide is harmful to the bromine oxygen layer, and it is banned in many countries.
Therefore, the treatment of container pests is a current problem, and conventional fumigation cannot solve the needs of the busy operation of container ports
[0003] At present, there is no report at home and abroad on how to quickly disinfeste the cargo container in transit

Embodiment Construction

[0014] A rapid method of fumigation of container loads such as figure 1 and figure 2 As shown, before the dosing, the air holes or leaks at the four top corners of the container 1 are sealed with adhesive tape, and the worm samples are evenly arranged in the box. Close the box door 2, then insert the fumigation injector needle 4 (commonly known as a syringe) from the overlapping position of the two box door films 3 at the bottom of the two box door seams of the container 1 at an angle of 45°C, unscrew the valve of the steel cylinder 8, and the valve in the steel cylinder 8 Sulfuryl fluoride is introduced into the container 1 through the pressure reducer 7, LZB-10 glass rotameter 6, oxygen tube 5, injector needle 4 (So 2 f 2 , content 99%) gas. If it is a 20-foot container, put in 1600g (about 50g / m 3 ), the time is 5-6 minutes; if it is a 40-foot container, put in 3350g (about 50g / m 3 ), the time is 10-12 minutes, and the dosing is completed, and the needle 4 of the inje...

Abstract

One quick fumigating method to stowage in container relates to that inserting pinhead of injector forming 45 deg. at the overlapping place of two rubber sheets on the door down the container's slot, by which injecting into fumigant of sulphuryl fluoride. This invention provides a convenience, shortcut way to fumigate and pesticide for container.

Description

technical field [0001] The invention relates to a quarantine treatment technology for container loads, which is suitable for the detoxification treatment of wood, bamboo, rattan, willow and wooden packing boxes and other products loaded in containers, and is especially suitable for the quarantine treatment of on-site containers at land transport ports. Background technique [0002] Container transportation has the characteristics of convenient loading and unloading, safe transportation and high utilization rate, and is widely used in land, sea and air transportation all over the world. In recent years, wood, rattan branches, bamboo branches, wicker and their products (including wooden packaging boxes) loaded in containers often have dangerous pests or living pests exceed the standard, and need to be fumigated. Conventional fumigation methods are usually carried out under closed conditions, such as fixed fumigation warehouses, warehouses or tents. However, due to the good ai...
