example 1

[0022] Example 1. A device used in the study of DMS gas release from Spartina salt marsh and its use method

[0023] The stainless steel support system is manufactured with reference to the attached drawings. The diameter of the base is 40cm. Two sets of stainless steel pipes (1m+0.6m) are used as intermediate supports to make the total height of the device reach 1.8m. The outer cover is made of polyperfluoroethylene transparent film, and the wafer gasket in the top frame and the joint in the air guide system are all made of silica gel. The components of the device are transported to the coastal spartina salt marsh, the base is covered with a certain amount of spartina vegetation and embedded in the ground, and two sets of middle steel pipes and connecting steel rings are inserted. Remove the screws of the top frame, put the cover film on the top frame and press its upper edge into the silicone gasket on the top frame, re-tighten the screws to fix the cover. Connect the top frame ...

[0024] Example 2. A CH used in rice fields 4 Release research device and how to use it

[0025] The stainless steel support system is manufactured with reference to the attached drawings. The diameter of the base is 40cm, and a set of stainless steel pipes (1m) are used as the intermediate support to make the total height of the device reach 1.2m. Polyethylene film is used as the outer cover, and the disc gasket in the top frame and the joint in the air guide system are respectively made of rubber and latex materials. The components of the device are transported to the edge of the paddy field, the base is covered with a certain amount of rice and embedded in the ground, and the middle steel pipe is inserted. Remove the screws of the top frame, put the cover film on the top frame and press the upper edge into the rubber gasket on the top frame, and tighten the screws again to fix the cover. Connect the top frame with the outer cover to the middle frame through the steel pipe butt j...

Abstract

The invention belongs to resource and environment engineering technical area, which involves the manufacture method of a disassemble portable gas collection device. The device contains stainless steel support system, a cover, an airproof system, a gas transmit system and the accessories. Most parts is disassembled, ití» easy to assemble in the open. This invention can be used as a gas collection device in environment air measurement and ecology research.

Description

1. Technical Field [0001] The invention belongs to the technical field of resource and environmental engineering, and relates to a portable gas sampling device and a use method thereof. 2. Background technology [0002] Except for the mobile sampling vehicle, the field air collection device used in the environmental monitoring process, the small simple device has no non-plexiglass gas box or stainless steel gas box. The common feature of the two types of sampling boxes is that the whole or most of the parts are glued, which leads to heavy handling and easy deformation and damage. At the same time, plexiglass has significant adsorption to certain gas components, which will directly affect the authenticity of the gas sample composition. When the stainless steel sampling box collects the gas released by the plant, because it is opaque, it will also affect the photosynthetic physiology of the plant and further affect the gas release. 3. Summary of the invention [0003] The purpose ...
