Description

Technical Field

[0001] This utility model relates to the field of dual-fluid spray gun technology, specifically to a high-efficiency atomizing dual-fluid spray gun. Background Technology

[0002] Denitrification is a treatment method that uses ammonia in ammonia water or urea solution to neutralize nitrogen oxides in flue gas, thereby reducing nitrogen oxides. Denitrification systems are generally divided into SCR denitrification systems and SNCR denitrification systems. In cement clinker production lines, SNCR denitrification systems, which do not use catalysts and do not require the installation of additional reactors, are usually used for denitrification. SNCR denitrification system is short for Selective Non-Catalytic Reduction Technology. SNCR denitrification system uses a preheater decomposition furnace as a reaction field to reduce NOx in the temperature range of 850 to 1100℃.

[0003] Existing high-efficiency atomizing dual-fluid spray guns atomize and spray combustibles by applying pressure to both gas and liquid to facilitate complete combustion of the fuel. While this method can achieve atomization of both liquid and gas, the gun barrel needs to be placed within the combustion chamber to spray the liquid and gas within the combustion range. Under prolonged high-temperature conditions, the gun barrel is prone to melting and heat buildup, resulting in a short service life. Utility Model Content

The threaded head 2 12 and the bottom of the barrel 4 are connected to a nozzle 8, a liquid flow plate 18 mounted on the bottom of the nozzle 8, and atomizing nozzles 2 17 disposed around the bottom of the liquid flow plate 18, with atomizing nozzles evenly distributed on the inner and outer sides of the atomizing nozzles 2 17. One-way valves 16 are installed inside nozzle 19, atomizing nozzle 19, and atomizing nozzle 17. Through the design of heat insulation sleeve 11, threaded head 10, and threaded head 22, when using the gun barrel 4, the threaded head 10 of the heat insulation sleeve 11 can be screwed onto the flange 7, realizing the protection of the gun barrel 4 by the heat insulation sleeve 11, preventing the gun barrel 4 from being directly burned by open flame and melting. At the same time, with the design of the heat dissipation cavity 9 on the inner wall of the threaded head 10, the heat between the heat insulation sleeve 11 and the gun barrel 4 can be discharged through the gap between them and the heat dissipation cavity 9, effectively avoiding the problem of heat accumulation affecting the life of the gun barrel 4.

[0018] like Figures 1-4 As shown, in this embodiment, the top of the crushing pipe 3 is connected to the mixing head 2 through the gas-liquid pipe 6. Two liquid inlet pipes 1 are symmetrically installed on the top of the two side walls of the mixing head 2. An air inlet pipe 5 is provided in the middle of the top of the mixing head 2. The bottom of the air inlet pipe 5 is connected to the gas-liquid pipe 6 through the inner pipe 13. Two mixing channels 14 are symmetrically opened on both sides inside the mixing head 2.

[0019] like Figures 1-4 As shown, in this embodiment, the gas-liquid pipe 6 is inserted into the crushing pipe 3, the gas-liquid pipe 6 is inserted into the mixing head 2, and the liquid inlet pipe 1 and the air inlet pipe 5 are both connected to the flange of the mixing head 2. The design of the liquid inlet pipe 1 and the air inlet pipe 5 facilitates the connection of external equipment to realize the transportation of liquid and gas.

[0020] like Figures 1-4 As shown, in this embodiment, the inner tube 13 passes through the mixing head 2, and the inlet pipe 1 is inserted into the mixing channel 14. The inner tube 13 realizes the delivery of gas, and the mixing channel 14 realizes the delivery of dual fluids.

[0021] like Figures 1-4 As shown, in this embodiment, both the breaker tube 3 and the gun barrel 4 are inserted into the flange 7, the threaded head 10 is threadedly connected to the flange 7, the heat dissipation cavity 9 passes through the threaded head 10, and the design of the threaded head 10 in conjunction with the threaded head 2 12 facilitates the individual replacement of the heat insulation sleeve 11 and the nozzle 8.

The crushing discs 15 are set in stages, which effectively ensures the crushing efficiency of the device for the liquid.

[0025] The specific implementation process of this embodiment is as follows: When using the device, the flange 7 of the device needs to be connected to the combustion treatment equipment to ensure the stability of the device during operation. At the same time, the air inlet pipe 5 of the device is connected to the high-pressure gas supply equipment, and the two liquid inlet pipes 1 are connected to the liquid supply equipment of different fuels respectively. During operation, the liquid enters the gas-liquid pipe 6 through the mixing channel 14, and the high-pressure gas enters the gas-liquid pipe 6 through the inner pipe 13, realizing the mixing between gas and liquid. Under the impact force of high-pressure gas, the liquid can be cut by the crushing disc 15. After the cutting of gas and liquid by the gun barrel 4, the liquid is atomized and sprayed by the atomizing nozzle 19 and the atomizing nozzle 2 17. The design of the one-way valve 16 makes it convenient to control the opening and closing of the atomizing nozzle 19 and the atomizing nozzle 2 17, thereby facilitating the uniform control of the spray volume of the device.
