Embodiment

[0017] Take the ammonia solution of preparation pH=8.8 as example, following steps:

[0018] (1) Generating source solution: Mix 150 g of solid ammonium chloride with 0.5 L of water.

[0019] (2) Buffer solution: Mix solid sodium carbonate and solid sodium bicarbonate at a ratio of 1:1 (23 g each), then add 0.5 L of water and stir well.

[0020] (3) Ammonia solution: Mix the source solution, buffer solution and water in a ratio of 1:1:2. The total amount of the ammonia solution can be adjusted according to the demand, but keep the ratio unchanged.

[0021] (4) Finally, 35 g of solid sodium carbonate was added to the ammonia solution.

[0022] Put the configured ammonia solution into the water storage tank 1, place the low-power circulating pump 2 at the bottom of the water storage tank 1, connect one end with a hose to extend from the water storage tank 1, connect it with the regulating valve 3, and put it into the test chamber 4. Connect one end of another hose to the coppe...

Abstract

The invention discloses a circulating system for supplying a stable liquid source for ammonia volatilization. A prepared ammonia solution is placed in a water storage tank; one end of a regulating valve is connected with a circulating pump arranged in the water storage tank through a first hose, and the other end of the regulating valve is connected into a test tank through a second hose; and one end of a third hose is connected into the water storage tank, the other end of the third hose is connected with the end of a right-angle copper pipe, which is parallel to the liquid level, and the end of the right-angle copper pipe, which is perpendicular to the liquid level, keeps consistent with the level of the ammonia solution. The volatilization speed of ammonia on the surface of the solution can keep stable; by using the circulating system, the characteristics such as pH value and total ammonia nitrogen concentration of the solution can keep roughly same within long time; the pH value of the solution can be regulated as required, and the operation is convenient. The circulating system provided by the invention can be used for preparing ammonia in scientific researches.

Description

technical field [0001] The invention relates to a circulation system for providing a stable ammonia volatilization liquid source. Background technique [0002] Ammonia is a colorless gas with a pungent odor. In recent years, ammonia emissions from livestock and poultry production systems have become an important source of air pollution, causing a series of ecological and environmental problems, which have attracted widespread attention from all over the world. Whether in developed countries or developing countries, with the continuous improvement of the scale and intensification of the livestock and poultry breeding industry, ammonia emissions are also increasing. Excessive discharge of ammonia gas into the atmosphere will cause direct or indirect harm to the surrounding water body, atmosphere, soil, human health and ecosystem of the farm. In addition, ammonia gas produced in livestock and poultry houses can cause rapid growth and metabolism of animal mucosal cells, result...
