Embodiment 1

[0075] A method for fast mechanical deoxygenation and nitrogen-enriched atmosphere adjustment and pest control in a closed compartment, in any symmetrical compartment (which can be a high-speed rail compartment, an aircraft cabin, a ship cabin, a container, or a bus compartment, referred to as "closed compartment", the same below) A 1-10 gas output pipes 1 and 1-10 gas input pipes 7 are respectively drawn from the two sides or the top and bottom of the airtight compartment. Choose the size of plastic, rubber or metal pipes with an inner diameter of 10-100mm, the gas output pipe (or gas discharge pipe) 1, the gas input pipe 7 is connected to the closed compartment through the pipe joint, and the pipe joint is used by Wuhan Dongchang Storage Technology Co., Ltd. The plastic joints of various specifications produced by the company are used to check for leaks and mend holes in the closed compartment, and use the negative pressure detection method to test the airtightness of the clo...

Embodiment 2

[0092] It is basically the same as Embodiment 1, except that the gas flow between the exhaust pipe of the closed compartment and the input gas pipe and the pressure inside and outside the system are kept in a balanced state by the following method. The gas flow detector L6 is set on the gas outlet 6 of the main component, the gas flow detector L2 is set at the raw material gas inlet 2 of the mechanical deoxygenation and nitrogen-enriching equipment, and the gas flow detector L8 is set on the nitrogen-enriched gas output pipeline 8. The detection quantity of the flow detector calculates the need for the mechanical nitrogen filling pressure tolerance linkage device C to compensate the nitrogen-rich gas compensation amount in the closed cycle mechanical deoxygenation and nitrogen filling system, and adjusts the control valve 9 so that the detection value of the "gas flow detector L8 ≈The detection value of the flow detector L2 - the detection value of the flow detector L6", the ab...

Embodiment 3

[0094] It is basically the same as Embodiment 1 and 2, except that a pressure sensor is set in the airtight compartment, and when the pressure sensor detects that there is a pressure difference inside and outside the airtight compartment, by adjusting the control valve of the nitrogen-enriched source of uniform pressure 9 to control the flow of nitrogen-rich gas in the nitrogen-rich gas output pipeline 8 to ensure that the pressure difference inside and outside the closed compartment A tends to balance. The pressure sensor in this embodiment can use the pressure sensor product of Honeywell (China) Co., Ltd.

Abstract

The invention belongs to the technical field of controlling harmful medium insects by mechanical nitrogen-filling gas conditioning, and particularly relates to a rapid mechanical deoxidation and nitrogen-enriching gas-conditioning insect prevention method for a closed carriage. The method is characterized in that a "mechanical nitrogen-charging pressure-allowing linkage device" is connected into the closed circulating mechanical deoxidation nitrogen-charging insect prevention system, and nitrogen-rich gas is directionally injected into the closed circulating deoxidation nitrogen production system through a nitrogen-rich gas output pipeline of the mechanical nitrogen-charging pressure-allowing linkage device, so that an internal-external pressure difference formed by continuous operation ofthe system can be balanced in time. A traditional open or semi-open gas taking mode is changed into a full-closed circulating gas taking mode, so that the operation load and the process management and control difficulty of an equipment system are reduced, the advantages of low power distribution power and large air volume of normal-pressure type deoxidation nitrogen-enriching equipment can be exerted, the problems of large power distribution and low efficiency of the traditional deoxidation nitrogen-enriching equipment are solved, the medium insect prevention and control problems in various carriages, plane cabins or ship cabins are solved, and particularly a system solution for preventing and controlling medium insects through rapid mechanical deoxidation and nitrogen charging is provided for high-speed rail marshalling carriages coming out in the daytime and going back to the night.

Description

technical field [0001] The invention belongs to the technical field of mechanical nitrogen-filled controlled atmosphere for preventing and controlling harmful vector insects, and in particular relates to a method for fast mechanical deoxygenation and nitrogen-enriched adjusted controlled insect control method in an airtight compartment. Background technique [0002] High-speed passenger-dedicated railway is an important infrastructure and the main artery of the national economy in my country. It has become a popular means of transportation and the backbone of the comprehensive transportation system, and plays an important role in promoting my country's economic and social development. Affected by its own structural characteristics, long-distance operation, and the setting of parking stations under different open environmental conditions, the interior of high-speed rail passenger carriages will be affected by vector insects (including mosquitoes, flies, rats, cockroaches, bedb...
