Description

Technical Field

[0001] The utility model relates to the technical field of denitrification ammonia water systems, in particular to a double-gun ammonia water flow control cabinet for denitrification ammonia water systems. Background Art

[0002] Denitrification ammonia is a chemical used to reduce nitrogen oxides in exhaust gas. It is a mixture of ammonia and urea and other compounds. It can catalyze the reduction reaction of nitrogen oxides at low temperatures and convert NOx into nitrogen and water vapor. The denitrification ammonia system is a complex system used to reduce nitrogen oxides in exhaust gas. It mainly uses ammonia as a reducing agent to react with NOx in the flue gas, thereby converting it into harmless nitrogen and water vapor. In order to accurately control the flow of ammonia and ensure that ammonia can be sprayed into the exhaust gas treatment device according to the preset parameters and requirements, a double-gun ammonia flow control cabinet is required.

[0003] The common double-gun ammonia flow control cabinet used in the denitrification ammonia system is usually composed of a cabinet structure, a double-gun flow control device, a control system, a power supply and circuit, a display and operation interface, a safety and protection system, and a ventilation and heat dissipation structure. By equipping two independent flow control devices and components such as flow meters, regulating valves and actuators inside, the flow of ammonia can be accurately controlled to achieve the working flow size of the spray gun, so that the spray gun can reach the best use state. This is the common double-gun ammonia flow control cabinet structure and use method for denitrification ammonia system. In the traditional double-gun ammonia flow control cabinet used in the denitrification ammonia system, air enters the inside of the connecting pipe, but there will be impurities in the air, which will collide with the inner wall of the pipe and cause wear on the inner wall of the pipe, thereby causing damage to the pipe, shortening the service life of the pipe, and increasing the cost of pipe replacement. For example, a double-gun ammonia flow control cabinet with patent number CN219999781U separates impurities in the air by adding a filter plate. However, in this method, impurities will form blockages on the filter plate after long-term use, causing the air to pass slowly or even unable to pass. The filter plate needs to be removed from the equipment pipeline and replaced. However, during the replacement process, the equipment cannot be used normally, and the disassembly and assembly operations are too complicated and inconvenient to use. Therefore, a double-gun ammonia flow control cabinet for a denitrification ammonia system is proposed. Utility Model Content
