Description

Technical Field

[0001] This utility model relates to the field of atomization equipment technology, specifically a dual-fluid spray system. Background Technology

[0002] In numerous coal-fired power plants, ports and docks, coal mines, cement plants, and other enterprises, a large amount of dust-generating raw materials are transported by dump trucks, generating a significant amount of dust. This dust not only causes serious pollution but also affects the health of workers, making them susceptible to silicosis. Furthermore, the dust can corrode factory equipment, hindering its normal operation.

[0003] The current solution is to use a spray gun to supply water and air to generate water mist to clean the dust. Under the high-speed interaction of the gas and liquid phases, fine and relatively uniform atomization is obtained. However, in practice, the atomization of a single spray gun cannot meet the needs of daily systems. Utility Model Content

[0018] Please see Figure 1-2This utility model provides a technical solution: a dual-fluid spray system, which includes a pump station system and a spray gun. The pump station system includes a liquid circuit device 1, an air circuit device 2, a control cabinet 3, and a spray system pump station 4. The liquid circuit device 1 is connected to the spray system pump station 4 through a water inlet pipe 5. The air circuit device 2 is connected to the spray system pump station 4 through an air inlet pipe 6. The spray system pump station 4 is connected to the water ring pipe 91 and the air ring pipe 92 in the humidification device 9 through a water circuit pipe 7 and an air circuit pipe 8. The humidification device 9 is also equipped with a thermal resistor 93. The humidification device 9 is a humidification tower or a humidification pipe. Three thermal resistors 93 are installed on the humidification device 9. The thermal resistors 93 are used to detect the temperature inside the humidification device 9.

[0019] The control cabinet 3 can set the pressure and flow rate of water in the liquid circuit device 1, the pressure and flow rate of air in the air circuit device 2, as well as the flue gas inlet temperature, flue gas outlet temperature, and the speed of the water pump in the spray system pump station 4. During operation, the control cabinet 3 will receive the temperature signal transmitted by the thermal resistor 93, and thus adjust the water spray volume and select the number of spray guns and the water spray volume according to the flue gas inlet and outlet temperatures of the humidification device 9.

[0020] The liquid circuit device 1 includes a filter 11, a water tank 12, a water level gauge 13, and an ultra-low water level alarm 14. The upper end of the water tank 12 is provided with a water inlet pipe 19, and the end of the water inlet pipe 19 is provided with a float valve 18. The filter 11 and valve 15 are installed on the water inlet pipe 19. The water level gauge 13 is installed on the side of the water tank 12. The water level gauge 13 is connected to the ultra-low water level alarm 14 and to the control cabinet 3.

[0024] Eight spray guns 94 are installed on the water ring pipe 91 and the air ring pipe 92. Four of them are uncontrolled spray guns, and the other four are group-controlled spray guns. Using eight spray guns, four of them are fixed spray guns, and the other four can be controlled to spray water into the humidification device 9 to cool down the high-temperature flue gas and reduce the temperature of the flue gas at the kiln tail during production to the desired value of the system.

[0025] The control system of the group-controlled spray gun 94 is connected by a water solenoid valve 941 and an air solenoid valve 942. A check valve 943 and a pressure regulating valve 944 are connected in parallel on the side of the air solenoid valve 942, which can open or close the group-controlled spray gun 94 according to the settings of the control cabinet 3.

[0026] Therefore, this dual-fluid spray system, which operates eight spray guns, four of which are uncontrolled and four are controlled, has the advantages of flexible operating condition adjustment, a large adjustment ratio, and high atomization quality, thus meeting the system requirements.
