Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal equipment that reduces energy consumption. Background Technology

[0002] In a pulse jet dust collector, when dust-laden gas enters the dust collector through the inlet, it first encounters the inclined plate and baffle in the middle of the inlet and outlet, and the airflow is turned and flows into the ash hopper. At the same time, the airflow speed slows down, and due to inertia, the coarse dust particles in the gas flow directly into the ash hopper. The system acts as a pre-dust collector. The airflow entering the ash hopper then turns upwards, passing through filter bags with internal metal frames. Dust is captured on the outer surface of the filter bags. The purified gas enters the upper clean air chamber of the filter bag chamber and is discharged through the outlet. During the purification process, as time increases, more and more dust accumulates on the filter bags, increasing their resistance and gradually reducing the processing airflow. For normal operation, the resistance must be controlled within a certain range (140-170 mm water column). If this range is exceeded, the filter bags must be cleaned. During cleaning, the pulse controller sequentially triggers each control valve to open the pulse valve. Compressed air from the air tank is injected through the venturi tubes of the blowpipe into the corresponding filter bags. The filter bags expand rapidly and instantly, causing the dust accumulated on their surface to fall off, and the filter bags return to their initial state. The cleaned dust falls into the ash hopper and is discharged from the machine through the ash removal system. This periodic pulse-jet cleaning of the dust accumulated on the filter bags ensures the normal passage of purified gas and guarantees the operation of the dust removal system.

[0003] For example, a dust collector disclosed in Chinese utility model CN218653545U mainly includes a housing. The space inside the housing is divided into a first space, a second space, and a third space from bottom to top. A filter cartridge is installed in the first space, and a fan is installed in the third space. A dust collection box is located below the filter cartridge. An air inlet is located on the side of the first space, above the dust collection box; and an air outlet is located on the side or top of the third space. This dust collector has a reasonable internal structure, a compact size, and occupies little space. However, due to the difference between the inlet and outlet air volumes, after long-term operation, the fan's air circulation is obstructed, resulting in excessive load on the internal fan, high energy consumption, and low product efficiency. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to design a dust removal device that reduces energy consumption, which can solve the problem that the existing dust collectors have excessive fan load and high energy consumption, resulting in low product efficiency.

[0005] To achieve the above objectives, this utility model provides a dust removal device with reduced energy consumption, comprising: a cabinet and a control system, a pulse dust collection system, and a wind circulation system arranged from top to bottom within the cabinet. The pulse dust collection system is electrically connected to the control system. The side wall of the cabinet is provided with an air inlet and an air outlet. The air inlet faces the pulse dust collection system, and the air outlet faces the wind circulation system. The wind circulation system includes a fan, a three-way pipe, and a pressure-stabilizing exhaust pipe. The control system is electrically connected to the fan. The compressed air duct of the pulse dust collection system is connected to the input end of the fan. One end of the pressure-stabilizing exhaust pipe is connected to the output end of the fan through the three-way pipe, and the other end of the pressure-stabilizing exhaust pipe is connected to the outside. The air outlet is connected to the middle of the three-way pipe.

[0006] Furthermore, the cabinet is provided with a first partition and a second partition with through holes from top to bottom. The first partition and the second partition divide the space inside the cabinet into a first chamber, a second chamber and a third chamber from top to bottom. The second chamber and the third chamber are connected. The control system is located in the first chamber, the pulse dust collection system is located in the second chamber, and the wind circulation system is located in the third chamber.

[0007] Furthermore, the control system includes a display panel and a central controller. The central controller is located in the first chamber, the display panel is located on the outer wall of the first chamber and is electrically connected to the central controller, and the central controller is electrically connected to the fan.

[0008] Furthermore, the pressure-stabilizing exhaust duct is arranged vertically, and the air outlet of the pressure-stabilizing exhaust duct is located at the upper end of the pressure-stabilizing exhaust duct.

[0009] Furthermore, the first chamber, the second chamber, and the third chamber are all equipped with doors that can be opened and closed.

[0010] Furthermore, each of the doors is provided with a sealing strip on its inner edge.

[0011] Furthermore, at least one side wall of the third chamber is provided with heat dissipation holes.

[0012] The beneficial effects of adopting the above technical solution are as follows: The dust removal equipment of this utility model is equipped with a pressure stabilizing exhaust component, which is connected to the output end of the fan through a three-way pipe. The air outlet is connected to an external dust removal head, which allows excess air at the output end of the fan to be discharged to the external environment through the pressure stabilizing exhaust component, so that the pressure at the input end and the output end of the fan are kept consistent, solving the problem of excessive fan load, thereby reducing energy consumption and improving the working efficiency of the product.

[0018] like Figure 1-4As shown, this utility model provides a dust removal device with reduced energy consumption, including: a cabinet 1 and a control system 2, a pulse dust collection system 3, and a wind circulation system 4 arranged from top to bottom inside the cabinet 1. The pulse dust collection system 3 is electrically connected to the control system 2. The side wall of the cabinet 1 is provided with an air inlet 5 and an air outlet 6. The air inlet 5 is directly opposite to the pulse dust collection system 3, and the air outlet 6 is directly opposite to the wind circulation system 4. The wind circulation system 4 includes a fan 41, a three-way pipe 42, and a pressure-stabilizing exhaust pipe 43. The control system 2 is electrically connected to the fan 41. The compressed air guide pipe 33 of the pulse dust collection system 3 is connected to the input end of the fan 41. One end of the pressure-stabilizing exhaust pipe 43 is connected to the output end of the fan 41 through the three-way pipe 42, and the other end of the pressure-stabilizing exhaust pipe 43 is connected to the outside. The air outlet 6 is connected to the middle of the three-way pipe 42. The air inlet 5 and air outlet 6 are respectively connected to the air outlet duct and air inlet duct of a dust collector head. The dust collector head recovers air containing particles, and the air containing particles flows through the air outlet duct of the dust collector head to the air inlet 5 of the dust removal equipment involved in this utility model, and then flows to the pulse dust collection system 3 for processing. After being filtered and purified, the air containing particles flows through the lower wind circulation system 4 and back to the air inlet duct of the externally connected dust collector head through the air outlet 6, forming a wind circulation. Since the air volume at the input and output ends of the fan 41 is inconsistent, a pressure difference will be generated, which will cause the fan 41 to be overloaded. By adding a pressure stabilizing exhaust pipe 43 and connecting the pressure stabilizing exhaust pipe 43 to the output end of the fan 41 through a three-way pipe 42, the excess air at the output end of the fan 41 can be discharged to the external environment through the pressure stabilizing exhaust pipe 43, so that the pressure at the input and output ends of the fan 41 is consistent, solving the problem of excessive fan load, thereby reducing energy consumption and improving the working efficiency of the product. As a preferred option, a placement box 17 can be provided on the outer surface of the cabinet 1. The placement box 17 is located near the air outlet 6 and is used to place the air inlet pipe connector of the external dust removal head.

[0019] The cabinet 1 has a first partition 7 and a second partition 8 with through holes arranged from top to bottom. The first partition 7 and the second partition 8 divide the space inside the cabinet 1 into a first chamber 10, a second chamber 11, and a third chamber 12 from top to bottom. The second chamber 11 and the third chamber 12 are connected. The control system 2 is located in the first chamber 10, the pulse dust collection system 3 is located in the second chamber 11, and the air circulation system 4 is located in the third chamber 12. The second chamber 11 has a front chamber 13 and a rear chamber 14, and a third partition 9 with through holes is provided between the front chamber 13 and the rear chamber 14. Through this structural design, the control system 2, the pulse dust collection system 3, and the air circulation system 4 are rationally planned inside the cabinet 1, making the product appearance more concise and beautiful.

[0020] The pulse dust collection system 3 includes: a filter cartridge 31 and a dust collection box 32 located in the front chamber 13, and a compressed air duct 33, an air storage tank 34, and a pressure reducing valve 35 located in the rear chamber 14. The control system 2 is electrically connected to the pressure reducing valve 35, which is located at the outlet of the air storage tank 34. The filter cartridge 31 covers the through hole of the third partition 9. The dust collection box 32 is located directly below the filter cartridge 31. The wind circulation system 4 is connected to the compressed air duct 33. One end of the compressed air duct 33 is connected to the filter cartridge 31, and the other end is connected to the pressure reducing valve 35. Air containing particulate matter flows through the air inlet 5 to the filter cartridge 31 for purification. The particulate matter is blocked by the filter cloth of the filter cartridge 31. The filtered air enters the filter cartridge 31 and flows to the compressed air duct 33, then flows to the wind circulation system 4 below and returns to the external dust collector through the air outlet 6. This allows the product and the external dust collector to circulate air intake, filtration, and exhaust, reducing the indoor dust concentration. The air tank 34 is used to store compressed air. The pressure reducing valve 35 can effectively control the internal pressure. The control system 2 controls the pressure reducing valve 35 to release compressed air to the filter cartridge 31 in a pulse. The particulate matter adsorbed by the filter cartridge 31 is blown down into the dust collection box 32 directly below after being vibrated, preventing particulate matter from accumulating on the filter cartridge 31 and weakening the filtration effect. As a preferred solution, the dust collection box 32 is a drawer type, which is convenient for users to clean the collected particulate matter.

[0021] In this utility model, the third partition 9 rationally divides the filter cartridge 31, dust collection box 32, compressed air guide pipe 33, air tank 34 and pressure reducing valve 35 into two spaces. The filter cartridge 31 is placed horizontally. This structural design allows the air tank 34 and pressure reducing valve 35 to be placed inside the box, achieving a reasonable layout of product components.

[0022] The control system 2 includes a display panel 21 and a central controller 22. The central controller 22 is located inside the first chamber 10, and the display panel 21 is located on the outer wall of the first chamber 10 and electrically connected to the central controller 22. The pressure reducing valve 35 and the fan 41 are both electrically connected to the central controller 22. The central controller 22 collects and processes all information about the product, and then presents the processed information through the display panel 21 on the side wall, facilitating real-time monitoring and timely adjustments of the product's status and data by the user.

[0023] The pressure-stabilizing exhaust duct 43 is arranged vertically, and the exhaust port of the pressure-stabilizing exhaust duct 43 is located at the upper end of the pressure-stabilizing exhaust duct 43. In this embodiment, the external dust collector head is placed on the ground. The upward extension of the pressure-stabilizing exhaust duct 43 can prevent the exhaust air from disrupting the stable air environment around the dust collector head. In other embodiments, the position of the exhaust port of the pressure-stabilizing exhaust duct 43 can be adjusted according to the placement position of the dust collector head.

[0024] Preferably, the compressed air guide pipe 33 is a rigid metal pipe. This structural design can avoid the problem of the compressed air guide pipe 33 being damaged due to excessive back-blowing force from the air tank 34.

[0025] Preferably, the first chamber 10, the second chamber 11, and the third chamber 12 are all equipped with openable and closable doors. This structural design facilitates the user's inspection and replacement of the product's internal parts.

[0026] Preferably, each door has a sealing strip 15 on its inner edge. The design of the sealing strip 15 enhances the sealing performance of the product and improves its working efficiency.

[0027] Preferably, at least one side wall of the third chamber 12 is provided with heat dissipation holes 16. The fan will generate heat during long-term operation, and the design of the heat dissipation holes 16 facilitates the dissipation of hot air in the third chamber 12 to the external environment.
