Description

Technical Field

[0001] The utility model relates to an adjustable fog-making mechanism, and more specifically, to an adjustable fog-making mechanism for efficient dust suppression and reduction. Background Art

[0002] Currently, in the field of air-blast water mist dust suppression and reduction environmental governance equipment, in order to further improve the dust suppression and reduction effect and break through the technical bottleneck, it is relatively common to achieve this through means and methods such as "reducing the particle size of fog droplets, increasing the number and density of nozzles (also known as spray heads)". However, the actual result is often that it not only increases water consumption, power consumption, and material consumption, but also easily forms spray-type water accumulation, resulting in secondary water pollution. In terms of the actual improvement of the dust suppression efficiency and effect of dust particles, it has long shown that the effort is multiplied but the result is half as much, or even there is almost no improvement. The reason is that a core crux that has been overlooked for a long time lies in the lack of relatively objective understanding and control of the initial physical characteristics of the fog state and fog phase, and the lack of reasonable regulation methods. Content of the Utility Model

[0003] The purpose of the utility model is to provide an adjustable fog-making mechanism for efficient dust suppression and reduction with a simple structure, low agglomeration, and small fog droplets in view of the above-mentioned deficiencies of the prior art.

[0004] The technical solution of the utility model is realized as follows: An adjustable fog-making mechanism for efficient dust suppression and reduction includes an air duct. A air supply component is provided at the rear end of the air duct. A fixed annular pipe is provided on the inner wall of the air outlet end of the air duct. An adjustable distance unit is provided on the inner wall of the air duct in front of the fixed annular pipe. A movable annular pipe is provided on the adjustable distance unit. A number of inclined atomizing nozzles are evenly distributed circumferentially on both the fixed annular pipe and the movable annular pipe. The included angle α between two adjacent atomizing nozzles is 20 - 30°.

[0005] At least two fixed annular pipes are evenly distributed at intervals on the adjustable distance unit, and the distance between two adjacent fixed annular pipes is equal to the maximum displacement distance of the adjustable distance unit.

[0006] In the above-mentioned adjustable fog-making mechanism for efficient dust suppression and reduction, the adjustable distance unit includes a movable frame provided on the inner wall of the air duct, and the movable annular pipe is installed on the movable frame. At least one guiding groove is provided on the side wall of the air duct, and a connecting block cooperating with the guiding groove is provided on the movable frame. An electric push rod connected to the connecting block is provided on the outer wall of the air duct through a fixed frame.

[0007] In the above-mentioned adjustable fog-making mechanism for efficient dust suppression and reduction, the adjustable distance unit is connected with a monitoring and control system for real-time detection of dust information to control and adjust the distance.

[0008] After adopting the above structure, the utility model sets the circumferential spacing between two adjacent atomizing nozzles to 20-30°, increasing the three-dimensional generation field of the initial fog state and greatly reducing the contact and agglomeration probability between the initial fog particles. Due to the low fog state agglomeration rate, the formed fog particles are smaller, which are easy to be transported by the wind for longer distances, and the fog coverage area is larger, effectively improving the suppression efficiency.

[0009] The position of the movable annular pipe is adjusted through the distance adjusting unit to adjust the agglomeration ratio of the initial fog particles, so that the overall fog state is adapted to the dust particle state, and thus the dust particles are fully fused to achieve efficient suppression.

[0016] Refer to Figures 1-4 As shown, an adjustable fog-making mechanism for efficient suppression of the present utility model includes an air duct 1, a rear end of the air duct 1 is provided with an air supply component 2, a fixed annular pipe 3 is provided on the inner wall of the air outlet end of the air duct 1, a distance adjusting unit 4 is provided on the inner wall of the air duct 1 at the front end of the fixed annular pipe 3, and a movable annular pipe 5 is provided on the distance adjusting unit 4; a plurality of inclined atomizing nozzles 6 are evenly distributed along the circumferential direction on both the fixed annular pipe 3 and the movable annular pipe 5, and the included angle α between two adjacent atomizing nozzles 6 is 20-30°.

[0017] The nozzle spacing is determined by the spray angle of the nozzle itself: the larger the spray angle, the smaller the spacing; the smaller the spray angle, the larger the spacing.

[0018] By increasing the distance between the annular pipes and the circumferential distance between two adjacent atomizing nozzles, the three-dimensional generation field of the initial fog state can be increased, and the contact and agglomeration probability between the initial fog particles can be greatly reduced. At the same time, due to the low fog state agglomeration rate, the formed fog particles are smaller and are easy to be transported by the wind to increase the range. Under the condition that the fan power does not increase, the fog spraying coverage area is larger.

[0019] By adjusting the position of the movable annular pipe through the distance adjusting unit to reduce the distance, the agglomeration ratio of the initial fog particles can be increased, and relatively large initial fog particles can be obtained for adapting to different dust particles.

[0020] The air supply component is composed of a fan, a guide plate, etc. The fixed annular pipe and the movable annular pipe are connected with a liquid supply unit. Its specific structure and connection method are common knowledge in the art and will not be elaborated here.

[0021] In this embodiment, the distance adjusting unit 4 includes a movable frame 4a arranged on the inner wall of the air duct 1, and the movable annular pipe 5 is installed on the movable frame 4a; at least one guide groove 4b is arranged on the side wall of the air duct 1, and a connecting block 4c cooperating with the guide groove 4b is arranged on the movable frame 4a; an electric push rod 4e connected with the connecting block 4c is arranged on the outer wall of the air duct 1 through a fixed frame 4d. The front and rear ends of the electric push rod are respectively hinged on the fixed frame and the connecting block, which can reduce the damage to the electric push rod caused by the vibration of the air duct body during use.

[0022] In this embodiment, at least 2 fixed annular pipes 3 are evenly distributed at intervals on the distance adjusting unit 4, and the distance between two adjacent fixed annular pipes 3 is equal to the maximum displacement distance of the distance adjusting unit 4. The three-dimensional generation field of the initial fog state is further improved through the atomizing nozzles on multiple fixed annular pipes.

[0023] In this embodiment, the distance adjusting unit 4 is connected with a monitoring and control system for real-time detecting dust information to control and adjust the distance. By monitoring information characteristics such as the particle size, concentration, and proportion of the dust through the monitoring and control system, the telescopic amplitude of the electric push rod is controlled, so as to correspondingly adjust the distance between the fixed annular pipe and the movable annular pipe, and further adjust the initial fog domain and the comprehensive fog state fog phase of the fog state created by the atomizing nozzles, so as to achieve a high proportion correspondence, matching, agglomeration, and melting and falling of the dust particles and the fog particles.

[0024] During use, according to the dust particle information obtained by the monitoring and control system, the distance between the movable annular pipe and the fixed annular pipe is adjusted through the electric push rod, the fan of the air supply component is started to supply air, the liquid is transported to the atomizing nozzle through the liquid supply unit to form a spray, and the fog is sprayed through the air transportation.

[0025] The above-described embodiments are the preferred embodiments of the present utility model, which are only used to conveniently illustrate the present utility model and do not impose any formal restrictions on the present utility model. Any person with ordinary knowledge in the relevant technical field, without departing from the technical features of the present utility model, uses the technical content disclosed by the present utility model to make equivalent embodiments with partial changes or modifications, and without departing from the technical feature content of the present utility model, still fall within the scope of the technical features of the present utility model.
