Ammonia gas absorbing and monitoring device and use method thereof

Abstract

The invention relates to an ammonia gas absorbing and monitoring device and a use method thereof. The ammonia gas absorbing and monitoring device comprises gas collecting branch circuits and a gas collecting main circuit, wherein each gas collecting branch circuit comprises a gas collecting tank, an absorbing bottle set and a buffer bottle; the absorbing bottle set comprises one or multiple absorbing bottles, the absorbing bottles are connected in series through an air exhaust tube when absorbing bottle set comprises multiple absorbing bottles, the absorbing bottles are filled with acid liquid for absorbing ammonia gas, an air inlet is formed in the gas collecting tank, the gas collecting tank is in tight connection with one end of a transmission pipe, the other end of the transmission pipe is arranged in the first absorbing bottle of the absorbing bottle set in a sealing manner, and the last absorbing bottle of the absorbing bottle set is connected with the buffer bottle through the air exhaust tube; and the gas collecting main circuit comprises a mixing bottle, the buffer bottle is connected with the mixing bottle in a sealing manner through a connecting pipe, and the mixing bottle is connected with an air pump through a pipeline arranged in a sealing manner.

Description

technical field [0001] The invention relates to an ammonia gas absorbing and monitoring device and a using method thereof, belonging to the field of environmental protection. Background technique [0002] All kinds of ammonia volatilization is one of the important factors causing air pollution, and the determination of ammonia absorption is of great significance to environmental protection. At present, commonly used ammonia monitoring methods include multi-point online sampling and airtight absorption. In order to make the monitoring results more accurate, the monitored object is required to be in a state of free volatilization, but the volatilized ammonia gas cannot be absorbed, which will not only cause the monitoring object The loss of its own nutrient content, and will pollute the environment. Due to the high cost and maintenance cost of multi-point online sampling and monitoring equipment, it cannot be applied on a large scale; while the closed absorption method is mos...

Problems solved by technology

At present, commonly used ammonia monitoring methods include multi-point online sampling and airtight absorption. In order to make the monitoring results more accurate, the monitored object is required to be in a state of free volatilization, but the volatilized ammonia gas cannot be absorbed, which will not only cause the monitoring object The loss of its own nutrient content, and will pollute the environment

Due to the high cost and maintenance cost of multi-point online sampling and monitoring equipment, it cannot be applied on a large scale; while the closed absorption method is mostly used to monitor the ammonia volatilization status of farmland and agricultural waste, etc. The devices and test methods used in the monitoring process are due to the airtightness of the device It is difficult to simulate the actual ammonia volatilization due to poor performance, and the accuracy and specificity are poor
