Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1 to Figure 3 As shown, the aquaculture waste composting ammonia discharge sampling device of the present invention comprises a drum 1, the drum 1 is hollow and one side is open, a support ring 2 is fixed on the opening side of the drum 1, and a gap is arranged in the middle of the drum 1, and the gap The inner wall of the horizontally symmetrical cylinder 1 is provided with a placement groove 4, and a pump-suction ammonia analyzer 3 is installed on the placement groove 4, and the placement groove 4 is slightly lower than the height of the gap, so that the pump-suction ammonia analyzer 3 is more convenient. It is convenient for installation. The outer ...

Abstract

The invention relates to the technical field of cultivation accessory devices, in particular to a breeding waste composting ammonia emission sampling device which comprises a barrel, wherein the barrel is hollow, an opening is formed in one side of the barrel, a supporting ring is fixed to the opening side of the barrel, a notch is formed in the middle of the barrel, an accommodating groove is formed in the position, horizontally symmetrical to the notch, of the inner wall of the barrel, a pump suction type ammonia gas analyzer is mounted on the placement groove, a cover plate is rotationally connected to the outer wall of the barrel and blocks the notch, a hook is fixed to the side, away from the opening, of the inner wall of the barrel through a support, and a fan is hung on the hook. According to the breeding waste composting ammonia emission sampling device, a static box is combined with an instrument analysis method, the operation is simple, the cost is low, the precision meets the experiment requirement, the experiment is easy to repeat, the data such as the ammonia emission speed, the ammonia emission concentration and the ammonia emission amount can be obtained, the application range is wide, and the influence of environmental conditions is small.

Description

technical field [0001] The invention relates to the technical field of aquaculture attachments, in particular to a sampling device for ammonia emission from aquaculture waste composting. Background technique [0002] A large amount of ammonia is emitted during the composting process of farm waste, and different climatic conditions and different production management methods all affect the ammonia emission during the composting process of farm waste. [0003] At present, the monitoring methods for ammonia emission from composting of aquaculture waste mainly include: chemical analysis method, spectroscopic method, instrument analysis method and sensor method, but there are certain defects in all of them: [0004] The chemical analysis method uses the color change in the chemical reaction or the acousto-optic signal after the reaction to measure the concentration of ammonia gas. The ammonia concentration is determined by offline analysis, and the sample gas is manually extracte...
