Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a filter-free pipeline dust removal system. Background Technology

[0002] Currently, dust removal technologies mainly include filter cartridge / bag dust collection, cyclone dust collection, spray dust collection, and electrostatic dust collection. However, these technologies all have significant drawbacks. Specifically:

[0003] 1. Regarding filter cartridge and filter bag technology, the current manufacturing technology for filter cartridges and filter bags used in dust removal can achieve the following levels: commonly used 5-20μm, which is almost ineffective in reducing PM2.5 (particles smaller than 2.5 micrometers); in special cases, it can reach 2μm, which will greatly reduce the air passage capacity when the PM2.5 reduction effect is not good; high power consumption; difficult to clean; large footprint; poor dust removal effect.

[0004] 2. Cyclone dust removal technology can only remove larger dust particles and is completely ineffective against fine particles suspended in the air, thus having no effect on reducing PM2.5.

[0005] 3. Spray dust removal technology can pollute equipment, factories, and roads; saturated air humidity can severely affect equipment safety and failure rate; it can also negatively impact the working environment; it consumes a large amount of water; and it can result in long dust removal times and poor performance.

[0006] 4. Electrostatic dust removal technology is ineffective in humid environments; its effect is poor at high concentrations and large volumes; it is greatly affected by airflow speed; it consumes a lot of power; and it is difficult to clean.

[0007] There are currently no effective solutions to the technical problems mentioned above.

[0008] Therefore, this utility model is proposed. Utility Model Content

[0009] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a filter-free pipeline dust removal system to solve the technical problems in related technologies.

[0010] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0011] According to one aspect of the present invention, a filterless pipeline dust removal system is provided, comprising at least one dust removal pipe assembly; each dust removal pipe assembly includes a pipe body, a nozzle assembly is provided inside the pipe body, the nozzle assembly is connected to a water supply system, the pipe body has a sewage discharge outlet, and is connected to a sewage discharge system through the sewage discharge outlet.

[0012] Optionally, the water supply system includes an external pressure water pipe disposed on the outside of the pipe body, the external pressure water pipe being connected to an internal pressure water pipe disposed on the inside of the pipe body via a pressure water pipe branch pipe, the outlet end of the internal pressure water pipe being connected to the inlet end of the nozzle assembly, and the external pressure water pipe also being connected to a water pump for pumping water to the water supply system.

[0013] Optionally, it also includes a nozzle assembly bracket, which is disposed inside the dust collection pipe assembly and connected to the inner wall of the dust collection pipe assembly, and the nozzle assembly is disposed on the nozzle assembly bracket.

[0014] Optionally, the wastewater discharge system includes a wastewater receiving tray connected to the outlet end of the wastewater discharge trough, and the bottom end of the wastewater receiving tray is connected to the wastewater discharge pipe via a wastewater connection pipe.

[0015] Optionally, the outlet end of the sewage discharge pipe is connected to a water pressure controlled sewage discharge valve.

[0016] Optionally, the dust removal system includes a main dust removal pipe and a dust removal manifold, wherein the dust removal manifold is connected to the main dust removal pipe as a branch of the main dust removal pipe;

[0017] The dust removal main pipe is composed of one or more dust removal main pipe assemblies connected end to end, and the dust removal manifold is composed of one or more dust removal manifold assemblies connected end to end;

[0018] Both the dust removal main pipe assembly and the dust removal manifold assembly are the dust removal pipe assembly.

[0019] Optionally, it also includes a fan, which is disposed at one or more locations in the air duct formed by the dust removal main and the dust removal manifold.

[0021] Optionally, the tube body is also provided with a window, and the window is provided with a window cover that can be opened, closed or removed.

[0022] The filter-free pipeline dust collection system provided by this utility model has the following advantages:

[0023] High efficiency and energy saving: Compared with traditional equipment, it can handle a larger air volume under the same power, and captures dust particles of all sizes indiscriminately, resulting in better dust removal effect. It also consumes less power for the same air volume.

[0024] High temperature resistance: Filter cartridges and bags are mostly made of polymer materials, which are prone to melting or combustion in high-temperature environments. Unlike flammable materials such as filter cartridges and bags, this system is not affected by high-temperature environments because it does not have a filter cartridge.

[0025] Cooling: Its internal water spray or fine water mist system can absorb a large amount of heat from the air and reduce the dust removal temperature.

[0026] Non-clogging: Its internal water spray or fine water mist system constantly flushes the inside of the pipes, keeping them clean. Waste inside the pipes is removed by the sewage discharge system.

[0027] Suppressing dust explosions: Its internal water spray or fine water mist system eliminates the static electricity of dust particles, increases the relative humidity of the air (supersaturation), and suppresses the impact sparks between dust particles and fan blades. This achieves the function of suppressing explosions.

[0028] Material-saving: No filter elements, filter bags, or other components are required, and there are no consumables; the rear-mounted air intake arrangement of the fan reduces wear on the fan blades.

[0029] Space-saving: Smaller size compared to other traditional devices with equivalent processing power.

[0030] Simple structure: The structure is relatively simple, the design is relatively easy, and the design cost is low. Low manufacturing cost: Due to the relatively simple structure, small size, light weight, and relatively low design and manufacturing costs. Attached Figure Description

Detailed Implementation

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0039] Combination Figure 1-5 The present invention provides a filterless pipeline dust removal system, including at least one dust removal pipe assembly; each dust removal pipe assembly includes a pipe body 1, a nozzle assembly 2 is provided inside the pipe body 1, the nozzle assembly 2 is connected to a water supply system, the pipe body has a sewage discharge outlet 3, and is connected to a sewage discharge system through the sewage discharge outlet 3.

[0040] In this embodiment, the dust collection pipe assembly includes multiple components and is divided into two types: a main dust collection pipe assembly 4 and a dust collection manifold assembly 5, the latter having a slightly smaller diameter than the former. One or more main dust collection pipe assemblies 4 are connected end-to-end to form a main dust collection pipe. One or more dust collection manifold assemblies 5 are connected end-to-end to form a dust collection manifold. The dust collection manifold connects to the main dust collection pipe as a branch, and can be coaxially connected to the main dust collection pipe or non-coaxially connected, such as perpendicularly connected.

[0041] It should be understood that various connection methods can be used between the various dust collection main pipe assemblies 4, between the various dust collection manifold assemblies 5, and between the dust collection main pipe assembly 4 and the dust collection manifold assembly 5, such as flange connection, welding, sleeve connection, etc., which are not limited in this embodiment. For example, in this embodiment, the various dust collection main pipe assemblies 4 are connected through dust collection main pipe connecting flange 6. The various dust collection manifold assemblies 5 are connected through dust collection manifold connecting flange 7. Multiple dust collection manifold assemblies 5 that are perpendicularly connected to the dust collection main pipe are first connected to the branch manifold 8, and then connected to the dust collection main pipe through the branch manifold 8. Dust collection manifolds arranged coaxially with the dust collection main pipe can be connected to the dust collection main pipe through reducing pipes 9.

[0042] The tail end of the dust collection main pipe can be connected to the fan 11 and the filterless dust collector 12 via a bend joint 10, etc., so that the purified gas is discharged from the outlet 13 of the filterless dust collector 12. The filterless dust collector 12 is existing technology and will not be described in detail here. It should be understood that the fan 11 can be set at... Figure 1 The location shown can also be set in other locations along the air duct. The form of the fan 11 (axial flow fan, centrifugal fan, or other types of fans, their model, size, etc. are not limited). The number, location, and series / parallel connection of the fans can take many forms, all of which fall within the scope of this patent protection.

[0043] The structural layout described above is the "suction mode" of this system's fans; alternatively, the fans can be installed in the "dust collection main duct" or 1 to n fans can be installed at any position in the middle of the "dust collection manifold" to achieve the "suction mode"; alternatively, 1 to n fans can be installed at the beginning of 1 to n "dust collection manifolds" to achieve the "suction mode". The latter two methods differ only in the number of fans and their installation positions, and are not illustrated here.

[0044] Below, as an example, the specific structure of the dust collector pipe assembly is further described. It should be understood that in the following embodiments, the structure of the dust collector pipe assembly can be either the structure of the dust collector main pipe assembly 4 or the structure of the dust collector manifold assembly 5, which will not be described again in the following embodiments. The dust collector pipe assembly also includes a nozzle assembly bracket 14, which is disposed inside the pipe body 1 of the dust collector pipe assembly and connected to the inner wall of the pipe body 1. The nozzle assembly 2 is disposed on the nozzle assembly bracket 14. For example, the nozzle assembly 2 can be annular, with multiple nozzles evenly arranged along the circumference of the annulus to form the nozzle assembly 2. The nozzle assembly 2 is connected to an internal pressure water pipe 15 disposed inside the pipe body 1, through which water is supplied to the nozzle assembly 2.

[0045] The surface of the pipe body 1 is also provided with a window, and a window cover 16 is provided on the window. The window cover 16 is connected to the pipe body 1 in an openable or detachable manner. In this way, by opening the window cover 16, the internal condition of the pipe body 1 can be observed, so that the dust removal pipe assembly can be cleaned or replaced in time when a fault or blockage occurs.

[0046] One or more sewage discharge outlets 3 are provided at the bottom of the pipe body 1, which can be arranged at intervals along the length of the pipe body 1 so as to discharge the sewage formed by the water mist sprayed by the nozzle assembly 2 and the particulate matter inside the pipe body 1.

[0047] As an example, the water supply system also includes an external pressure water pipe 17 disposed outside the pipe body 1. The entire dust collection main pipe or dust collection manifold can share a single external pressure water pipe 17. This external pressure water pipe 17 can be arranged coaxially and parallel to the dust collection main pipe and / or dust collection manifold. The external pressure water pipe 17 is connected to the internal pressure water pipe 15 in each section of the dust collection pipe assembly via pressure water pipe branch pipes 18, thereby diverting water to the interior of each dust collection pipe assembly. For example, the external pressure water pipe 17 can include multiple sections, each section having a pressure water pipe tee 19 connected to its end. One end of the tee is connected to the adjacent pressure water pipe at the other end, and the other end is connected to the pressure water pipe branch pipe 18. The pressure water pipe branch pipe 18 is connected to the internal pressure water pipe 15 via pressure water pipe connectors 20 and right-angle elbows 21. The water pump can be built into the filterless dust collection equipment or externally mounted (not shown in the figure), connected to the external pressure water pipe 17, thereby pumping water into each dust collection pipe assembly.

[0048] As an example, the wastewater discharge system includes a wastewater receiving tray 22 connected to the outlet end of the wastewater discharge channel 3. The wastewater receiving tray 22 can be arranged at an angle to facilitate wastewater discharge. The bottom end of the wastewater receiving tray 22 is connected to the wastewater discharge pipe 26 via a wastewater receiving tray outlet pipe 23, a wastewater connecting pipe 24, and a wastewater connecting pipe flange 25. The wastewater discharge pipe 26 can be shared by multiple dust collector pipe assemblies, that is, each dust collector pipe assembly is connected to the shared wastewater discharge pipe 26, which is arranged coaxially and parallel to the pipe body, through its wastewater receiving tray outlet pipe 23 and wastewater connecting pipe 24.

[0049] The outlet end of the sewage discharge pipe 26 can be connected to the vertical extension pipe 28 via the sewage pipe elbow 27, and then connected to the water pressure control drain valve 29. When the water pressure reaches the threshold, the valve automatically opens to discharge sewage.

[0050] Depending on the diameter of the sewage pipe, the flow slope (pipeline layout slope), the drop, and the amount of sewage, 1 to n sewage pipes can be set up. Each sewage pipe discharges into a pre-set sewage pipe (not shown in the figure) or sewage channel (not shown in the figure) on site through a sewage discharge valve controlled by its water pressure, and then flows into a sewage sedimentation tank (not shown in the figure) for recycling.

[0051] As an example, this dust removal system can operate as follows:

[0052] Start the water pump to pressurize the water and then deliver it through the pressurized water pipeline to the nozzle assembly 2 of the dust removal main assembly 4, the manifold 8, and the dust removal manifold assembly 5, forming a water spray or fine water mist (selected according to the nature of the dust on site).

[0053] When the blower 11 is started, the dusty and polluted air is drawn into the dust collection manifold assembly 5 and then collected into the manifold collection pipe 8, entering the dust collection main assembly 4. As the dusty and polluted air flows through these pipes, it mixes with the water spray or fine water mist generated by the nozzle assembly 2 inside, forming "mud mist". The mud mist collides to form "mud droplets", which drip down into the sewage discharge trough under the action of gravity, and then enter the sewage receiving tray 22. Through the sewage pipeline and its water pressure-controlled sewage discharge valve, it flows into the pre-set sewage discharge pipe (not shown in the figure) or sewage ditch (not shown in the figure), and then flows into the sewage sedimentation tank (not shown in the figure) for recycling.

[0054] The polluted air containing a small amount of mud mist (with significantly reduced dust content) passes through fan 11 and then enters filterless dust collector 12 for further purification. The purified air flows out through outlet 13 of filterless dust collector 12. Alternatively, a pipe can be connected to the outlet to transport the purified air to the required location.

[0055] In this utility model, the material, size, model, etc. of all pipes are not limited, and soft pipes, hard pipes, or semi-hard pipes are all within the scope of protection of this patent.

[0056] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
