Description

Technical Field

[0001] The invention belongs to the technical field of dust collectors and relates to an adaptive spray regulating dust collector and a control method thereof. Background Art

[0002] In industrial production and mining, dust pollution is a long-standing problem that needs to be solved. The presence of dust not only causes wear and blockage on equipment, shortening its service life, but also poses a serious threat to the health of operators. Therefore, the application of industrial dust removal equipment is becoming more and more widespread.

[0003] Most existing dust removal equipment uses fixed nozzles for spray dust reduction. Spray parameters such as flow rate and pressure cannot usually be adjusted adaptively according to environmental changes, resulting in unsatisfactory dust removal effects. In addition, different environments have different requirements for nozzle types, and traditional equipment often cannot flexibly switch nozzles, further affecting dust removal efficiency. Therefore, it is particularly important to develop a spray system that can be adaptively adjusted according to spray parameters. Summary of the invention

[0004] In view of this, the purpose of the present invention is to solve the above-mentioned problems and to provide an adaptive spray-adjustable dust collector and a control method thereof. According to the requirements of the adaptive adjustment control strategy of the dust collector spray parameters, a spray rack with automatic switching of nozzle types is designed, and a control system for automatic switching of spray flow, spray pressure, and nozzle type is developed, wherein the spray pressure is adjusted by a frequency converter, the spray flow is adjusted by an electric ball valve, and the nozzle switching is adjusted by a solenoid valve.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] An adaptive spray regulating dust collector comprises a dust collector body and an adaptive spray system for spraying dust reduction arranged in the dust collector body; the adaptive spray system comprises a spray rack, a solenoid valve, an electric ball valve, a pressurized water supply pump, and a controller;

[0007] The pressurized water supply pump is provided with a frequency converter, and the pressurized water supply pump is connected to the spray rack through a pipeline, and the pipeline is provided with an electric ball valve, a pressure and flow sensor; there are multiple spray racks, each of which has a different nozzle type, and each spray rack is connected to an independently controlled solenoid valve, and the spray rack is switched and controlled by the solenoid valve; the solenoid valve, the electric ball valve, and the pressurized water pump are all connected to a controller and controlled by the controller; the controller automatically switches and controls the spray flow, spray pressure, and nozzle type according to the requirements of the spray parameter adaptive adjustment control strategy.

[0008] Among them, the nozzle types include fan nozzles, cone nozzles and column nozzles.

[0009] A control method for the above-mentioned adaptive spray adjustment dust collector, the controller automatically switches the spray flow, spray pressure, and nozzle type according to the spray parameter adaptive adjustment control strategy requirements, and the specific control strategy is as follows:

[0010] Spray flow control: The spray flow is adjusted by the electric ball valve on the pipeline. The controller adjusts the opening of the electric ball valve in real time according to the feedback signal of the flow sensor to meet the spray volume of different dust reduction requirements; the feedback signal range of the flow sensor is 0 to 200 liters / minute;

[0011] Spray pressure control: The spray pressure is adjusted by the frequency converter on the pressurized water supply pump, and the control range is 0.5MPa to 2.5MPa. The pressure sensor monitors the system pressure in real time and feeds the data back to the controller. When the pressure deviates from the set range, the controller adjusts the output pressure of the pump by adjusting the frequency of the frequency converter. For example, when the pressure is lower than 1.0MPa, the controller will increase the pump speed to increase the system pressure; when the pressure exceeds 2.0MPa, the controller will reduce the pump speed to prevent overpressure.

[0012] Nozzle type switching: Nozzle type switching control: The detection range of the dust concentration sensor is 0~1000mg / m 3 According to the detected dust concentration, the controller automatically selects the appropriate nozzle type and adjusts the spray flow and pressure to achieve the best dust reduction effect.

[0013] When the dust concentration is >700mg / m 3 When the dust concentration is high, the controller selects the columnar nozzle for high-pressure long-distance spraying, the spray pressure is adjusted to 2.0-2.5MPa, and the spray flow rate is adjusted to 80-100L / min to ensure rapid and effective dust reduction;

[0014] When the dust concentration is 400~700mg / m 3 When the dust concentration is medium, the controller selects the conical nozzle for medium-distance spraying, the spray pressure is adjusted to 1.5-2.0 MPa, and the spray flow rate is adjusted to 50-80 liters / minute, taking into account the dust reduction effect and water resource utilization efficiency.

[0015] When the dust concentration is less than 400mg / m 3 When the dust concentration is low, the controller selects the fan-shaped nozzle to cover a large area with spray, the spray pressure is adjusted to 0.5-1.5 MPa, and the spray flow rate is adjusted to 10-50 liters / minute to cover a larger area and keep the environment clean.

[0016] The beneficial effects of the present invention are:

[0017] 1. The dust collector of the present invention can respond to changes in environmental conditions in real time by adaptively adjusting the spray flow, spray pressure and nozzle type through a controller. For example, when the dust concentration is high, the system will automatically select a suitable nozzle type (such as a columnar nozzle) and adjust the spray flow and pressure to ensure a high dust removal efficiency; when the dust concentration is low, the system will select a fan-shaped nozzle to reduce the waste of water resources. This adaptive adjustment function significantly improves the dust removal effect and ensures that the best dust removal performance can be achieved in different working environments.

[0018] 2. The present invention can more effectively capture and remove dust particles in the air by precisely controlling the spray parameters. For example, in an environment with high dust concentration, the system will increase the spray pressure and flow rate to ensure sufficient water mist coverage and settling speed, thereby improving dust removal efficiency. In an environment with low dust concentration, the system will reduce the spray flow rate and pressure to optimize the dust removal effect. This precise control helps to improve the overall dust removal efficiency and reduce dust residue.

[0019] 3. Traditional spray systems often waste water and energy due to fixed spray parameters. The present invention avoids unnecessary use of excessive water and energy by adjusting the spray flow and pressure in real time, thereby saving water and energy. At the same time, the adjustment function of the frequency converter and electric ball valve in the spray system also helps to optimize the use efficiency of energy and reduce operating costs.

[0020] 3. The intelligent control system of the present invention can automatically adjust the spray parameters, reduce the need for manual intervention, and simplify the operation process. This not only reduces the workload of operators, but also reduces the risk of unstable dust removal effects due to human errors. In addition, the automatic switching function of nozzle types reduces the need for equipment replacement during maintenance work, making equipment maintenance more convenient and quick.

[0021] 4. By integrating sensors (such as flow sensors, pressure sensors and dust concentration sensors), the dust collector of the present invention can monitor the environmental status in real time and make intelligent adjustments. This intelligent control system not only improves the automation level of the equipment, but also enhances the system's ability to adapt to complex environmental changes, making dust removal more accurate and efficient.

[0022] 5. The spray system of the present invention can automatically select the most suitable nozzle type according to the change of dust concentration, ensuring that a good dust removal effect can be maintained under different dust concentrations. This design enhances the environmental adaptability of the system, enabling it to operate stably in a changing industrial environment, thereby providing a continuous and reliable dust removal solution.
