[0018] In the following description, a lot of specific details are set forth in order to fully understand the utility model, however, the utility model can also be implemented in other ways different from the description herein, therefore, the utility model is not limited to the specific embodiments disclosed in the following disclosure.

[0019] Embodiment 1, as Figure 1 Indicated, a kind of boiler ignition operation dust control device, including high-pressure water source 1, high-pressure water source 1 provides clean water, uses high-pressure water to inhibit the release of dust, so that it reduces dust in ignition process as far as possible, effectively reduces air pollution. The high-pressure water source 1 is connected to boiler 5 by high-pressure water pipe 2, boiler 5 as main combustion equipment, carries out the heating and conversion of fuel, when ignition, there can be cinder and unburned fuel in the interior of boiler 5, produce a large amount of dust, utilize by water spray control dust emission when ignition. High-pressure water pipe 2 is responsible for the delivery of high-pressure water.

[0020] The top of the boiler 5 is connected to the dust collector 7 through the dust removal pipeline 6, which is used to purify the flue gas and dust passing through, remove dust particles by filtering, settling and other methods, reduce the impact on the environment, and provide clean air discharge. The dust removal pipeline 6 connects the top of the boiler 5 and the dust collector 7, which is responsible for collecting the dust released from the boiler 5, and processing before effective discharge, improving the level of environmental health.

[0021] The bottom of the boiler 5 is connected to the dust removal pipeline 6 through the dust removal air pipe 8, which connects the bottom of the boiler 5 and the dust removal pipeline 6, and is responsible for sending the dust and flue gas in the dust removal pipeline 6 back to the boiler 5 for spray dust removal, improving the treatment effect of solid particles. The rear side of the dust collector 7 is connected to the chimney 12 through the discharge pipeline 10, and the chimney 12 discharges the flue gas into the atmosphere, and the discharge pipeline 10 discharges the treated gas to the chimney 12 for discharge.

[0022] Now let's talk about the specific design of the above key components:

[0023] The high-pressure water pipe 2 is provided with a spray pipe 3, and the spray pipe 3 is provided with a spray head 4 at the end. The high-pressure water pipe 2 is designed to use materials that are resistant to high temperature and high pressure, such as stainless steel or alloy materials, to ensure safety in high temperature and high pressure environments. The pipe diameter of the high-pressure water pipe 2 should be calculated according to actual needs to ensure sufficient water flow and stable pressure.

[0024] The number of spray pipes 3 is several, and the number of spray heads 4 is corresponding to the number of spray pipes 3, and the spray heads 4 are installed at the observation port position of the boiler 5. The spray pipe 3 should be configured with several, arranged according to the size and shape of the boiler 5, to ensure that it can cover the entire furnace body and uniformly spray water mist. The length, diameter and nozzle aperture of each spray pipe 3 are designed as needed to achieve the best atomization effect. Each spray pipe 3 is provided with a spray head 4 at the end, and the spray head 4 is adjustable, which can adjust the spray angle and water flow rate as needed. The spray head 4 should be installed at the observation port position of the boiler 5 to facilitate monitoring and maintenance, while ensuring that the spray can effectively cover the environment.

[0025] The dust removal air pipe 8 is provided with a dust removal fan 9. The dust removal air pipe 8 is designed to use high-strength materials with appropriate diameter to ensure corrosion resistance and wear resistance. The inner wall of the dust removal air pipe 8 is kept smooth to reduce resistance and ensure smooth airflow. The dust removal air pipe 8 should be provided with reasonable support and fixing device, which will not deform under high load. The dust removal fan 9 selects a high-efficiency, low-noise fan to ensure sufficient air volume to absorb the flue gas in the dust removal pipeline 6. The dust removal fan 9 is equipped with a frequency converter to control and adjust the speed to adapt to different working requirements. At the same time, in addition to the traditional axial flow fan, centrifugal fan can also be considered to improve the dust removal efficiency.

[0026] The induced draft fan 11 is arranged on the exhaust duct 10. The exhaust duct 10 is made of anticorrosive material and is designed to be of proper size to reduce air flow resistance. The bends in the exhaust duct 10 should be reduced as much as possible to ensure the linearity of the flue gas flow and reduce the pressure loss. The induced draft fan 11 has high efficiency and adjustable speed function to adapt to different circulation requirements, including multi-stage fan or variable frequency drive, which can effectively handle the sudden flue gas flow while running stably and improve the overall emission efficiency.

[0027] The detector is arranged on the exhaust duct 10 and is interlocked with the dust removal fan 9. The dust detector based on laser, infrared or electrochemical principle can be selected or designed to monitor the dust concentration in the exhaust duct 10 in real time. The position of the detector should be able to accurately reflect the air flow state at the end of the duct. The detector and the dust removal fan 9 are connected through control interlocking. When the dust concentration exceeds the set threshold, the dust removal fan 9 is automatically adjusted to start, the air flow suction is increased, the flue gas in the dust removal duct 6 is sucked away, and the dust concentration is reduced through spraying.
