Portable Atmospheric Sampling Device

Abstract

The invention belongs to the field of gas sampling and detection equipment for livestock and poultry houses, and in particular relates to a portable air sampling device. The device includes a sampling part and an absorbing bottle, the absorbing bottle includes a bottle body and a bottle cap, and the corresponding absorbing liquid is contained in the cavity of the bottle body to react with the specified sampling gas; the absorbing bottle also includes an equalizing tube, and the inlet pipe of the equalizing tube is connected to the sampling part At the gas outlet end, the gas outlet tube runs through the bottle cap and extends below the liquid level of the absorption liquid. The section of the tube body near the bottom of the bottle body is in a spiral structure. The tube body of the spiral structure is densely covered to connect the lumen environment and the bottle Air distribution holes for the cavity environment; air escape holes are provided on the bottle cap; the device also includes a placement frame fixed at a designated part of the human body and can simultaneously place a plurality of the above-mentioned absorption bottles. The device is simple in operation, low in price, easy to carry, and can realize the requirement of rapid multi-point sampling of gas samples distributed at different levels in the space of livestock and poultry houses.

Description

technical field [0001] The invention belongs to the field of gas sampling and detection equipment for livestock and poultry houses, in particular to a portable air sampling device which is easy to operate and is easy to carry and move in the livestock and poultry houses. Background technique [0002] With the rapid development of the breeding industry, livestock and poultry breeding has changed from a traditional feeding model to a modern feeding model with large scale and high level of intensification. The livestock and poultry houses set up under the modern breeding mode, due to the compactness of their own breeding space, the indoor space, especially the closed livestock and poultry houses, is often enriched with livestock and poultry respiration, excrement and organic matter decomposition in the production process. Harmful gases such as ammonia, hydrogen sulfide, carbon dioxide and methane. According to relevant studies, the contribution rate of the environmental condit...

Problems solved by technology

Due to the complex structure and bulky size of the current general-purpose traditional atmospheric sampling device, complicated operation and high cost, it is especially inconvenient to carry and cannot be moved at will, and is highly dependent on power, so it is often only suitable for fixed-point sampling and not suitable for livestock breeding. Promoted in multi-point monitoring of industrial environment
