Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically a cyclone dust removal and desulfurization device. Background Technology

[0002] Cyclone dust collectors are a commonly used type of dust removal device. The principle of cyclone dust removal is to make the dust-laden airflow rotate, and with the help of centrifugal force, the dust particles are separated from the airflow and captured on the wall of the device. Then, the dust particles fall into the ash hopper for collection by gravity.

[0003] However, most cyclone dust removal and desulfurization devices on the market still have some shortcomings in use. For example, it is not convenient to replace and clean the ash hopper in a timely manner when using existing cyclone dust removal and desulfurization devices. Moreover, when collecting dust particles, some dust particles are easily lifted by the airflow. Long-term accumulation can easily lead to blockage of the air outlet pipe, thus having certain defects in use. Therefore, we propose a cyclone dust removal and desulfurization device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cyclone dust removal and desulfurization device to solve the problems mentioned in the background art, such as the inconvenience of timely replacement and cleaning of the ash hopper during use, and the fact that some dust particles are easily lifted by the airflow when collecting dust particles, which can easily lead to blockage of the air outlet duct over a long period of time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cyclone dust removal and desulfurization device, comprising an upper tower body and a lower tower body fixedly connected to the lower end of the upper tower body, wherein an installation pipe is integrally fixedly connected to the lower end of the lower tower body, and a dust collection mechanism is fixedly installed at the lower end of the installation pipe through a flange structure, and an exhaust pipe is fixedly installed on the upper end face of the upper tower body.

[0006] A blower is installed on the rear side of the upper tower body, and an air inlet pipe is fixedly connected to the upper end of the blower. A valve is fixedly installed inside the air inlet pipe. Baffles and guide strips are welded and fixed to the inner surface of the lower tower body.

[0007] As a preferred technical solution of this utility model, the dust collection mechanism includes a dust collection pipe fixedly installed at the lower end of the installation pipe through a flange structure, and the vertical cross section of the dust collection pipe is set in an inverted funnel shape. The lower end of the dust collection pipe is integrally fixedly connected to a dust collection chamber.

[0008] As a preferred technical solution of this utility model, the vertical cross-section of the lower tower body is set in the shape of a frustum, and the guide strip is spirally attached and fixed to the inner surface of the lower tower body from top to bottom.

[0009] As a preferred technical solution of this utility model, the exhaust duct is connected to the upper end face of the upper tower body, and the exhaust duct is set along the same vertical center line as the upper tower body. The baffle is set inclined downward on the side close to the vertical center line of the upper tower body.

[0010] As a preferred embodiment of this utility model, a collection plate is slidably provided on the inner side of the dust collection chamber, and a side plate is provided on the upper end surface of the collection plate.

[0011] As a preferred embodiment of this utility model, a sealed door is fixedly installed at the front end of the collecting plate, and a handle is fixedly connected to the front end face of the sealed door.

[0012] As a preferred technical solution of this utility model, the Y-direction cross section of the side plate is arranged in a right-angled triangle, and the side plate is fixedly connected between the sealed door and the collection plate. The side plate is symmetrically arranged about the vertical center line of the sealed door.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the cyclone dust removal and desulfurization device solves the problem that the existing cyclone dust removal and desulfurization device is not convenient to replace and clean the ash hopper in a timely manner during use, and that when collecting dust particles, some dust particles are easily lifted by the airflow, which can easily lead to blockage of the air outlet duct over a long period of time.

[0014] 1. The dust collection mechanism collects dust particles falling inside the lower tower body. A collection plate is slidably installed on the inner side of the dust collection chamber. Pulling the handle allows the collection plate to be pulled out, and the dust particles on the inner side of the collection plate and side plate can be cleaned in time, making it more practical.

[0015] 2. The airflow is fixedly connected to the inner surface of the lower tower body in a spiral shape by the guide strip. The airflow flows in a spiral shape inside the lower tower body. Dust is collected on the surface of the lower tower body and falls down. Since the baffle is set inclined downwards on the side close to the vertical center line of the upper tower body, the baffle plays a certain role in blocking the dust particles. When the dust particles reach the height of the baffle, they are blocked by the baffle, the movement trajectory changes and they fall down along the inner surface of the lower tower body. The dust particles fall into the dust collection mechanism through the installation pipe and are collected. This solves the problem that in the existing cyclone dust removal and desulfurization device, some dust particles are easily lifted by the airflow when collecting dust particles, and long-term accumulation can easily lead to blockage of the air outlet duct.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, and back, are based on the directions shown in the figures of this utility model, and are explained here together.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a cyclone dust removal and desulfurization device, including an upper tower body 1 and a lower tower body 2 fixedly connected to the lower end of the upper tower body 1. An installation pipe 3 is integrally fixedly connected to the lower end of the lower tower body 2. A dust collection mechanism is fixedly installed at the lower end of the installation pipe 3 via a flange structure. An exhaust pipe 7 is fixedly installed on the upper surface of the upper tower body 1. A blower 4 is provided on the rear side of the upper tower body 1, and an air inlet pipe 5 is fixedly connected to the upper end of the blower 4. A valve 6 is fixedly installed inside the air inlet pipe 5. Baffles 9 and guide strips 10 are welded and fixedly fixed to the inner surface of the lower tower body 2. Figure 1 As shown in the figure, the blower 4 is connected to the upper tower body 1 through the air inlet pipe 5, and the blower 4 pumps the industrial waste gas into the interior of the upper tower body 1 through the air inlet pipe 5.

[0024] Specific examples Figure 1 and Figure 2 As shown, the dust collection mechanism includes a dust collection pipe 801 fixedly installed at the lower end of the mounting pipe 3 via a flange structure, and the vertical cross section of the dust collection pipe 801 is set in an inverted funnel shape. The lower end of the dust collection pipe 801 is integrally fixedly connected to a dust collection chamber 802. Since the dust collection pipe 801 is connected to the lower tower body 2 through the mounting pipe 3, the dust collection mechanism collects the dust particles falling inside the lower tower body 2.

[0025] A collection plate 11 is slidably arranged inside the dust collection chamber 802, and a side plate 13 is provided on the upper end surface of the collection plate 11. The Y-direction cross section of the side plate 13 is arranged in a right-angled triangle, and the side plate 13 is fixedly connected between the sealing door 12 and the collection plate 11. The side plate 13 is symmetrically arranged about the vertical center line of the sealing door 12. The sealing door 12 is fixedly installed at the front end of the collection plate 11, and a handle 14 is fixedly connected to the front end face of the sealing door 12. By pulling the handle 14, the collection plate 11 can be pulled out, and the dust particles inside the collection plate 11 and the side plate 13 can be cleaned in time.

[0026] The working principle of this utility model is as follows: When using this cyclone dust removal and desulfurization device, first open valve 6, and pump industrial waste gas into the upper tower body 1 through the air inlet pipe 5 via blower 4, specifically as follows: Figure 1 and Figure 4 As shown, the vertical cross-section of the lower tower body 2 is set in a frustum shape, and the guide strip 10 is spirally attached to the inner surface of the lower tower body 2 from top to bottom. The airflow flows in a spiral shape inside the lower tower body 2, and the dust is collected on the surface of the lower tower body 2 and falls.

[0027] Specific examples Figure 1 and Figure 3 As shown, the baffle 9 is inclined downwards near the vertical center line of the upper tower body 1. The baffle 9 provides a certain degree of shielding for dust particles. When the dust particles reach the height of the baffle 9, they are blocked by the baffle 9, their movement trajectory changes, and they fall along the inner surface of the lower tower body 2, causing the dust particles to fall into the dust collection mechanism through the installation pipe 3 for collection. Specifically, as shown... Figure 1 and Figure 2 As shown, the collection plate 11 can be pulled out by the handle 14 to clean the dust particles inside the dust collection mechanism. This is how the cyclone dust removal and desulfurization device is used.

[0028] As described above, this utility model collects dust particles falling inside the lower tower body through a dust collection mechanism. A collection plate is slidably installed on the inner side of the dust collection chamber. Pulling the handle allows the collection plate to be pulled out, enabling timely cleaning of dust particles on the collection plate and the inner side of the side plate, thus improving practicality. Simultaneously, a guide strip is spirally fixed to the inner surface of the lower tower body, causing the airflow to flow in a spiral shape inside the lower tower body. Dust particles accumulate on the surface of the lower tower body and fall down. Because the baffle is inclined downwards near the vertical center line of the upper tower body, it provides a certain degree of shielding for the dust particles. When the dust particles reach the height of the baffle, their movement trajectory changes due to the shielding effect, and they fall down along the inner surface of the lower tower body. This allows the dust particles to fall into the dust collection mechanism through the installation pipe for collection. This solves the problem in existing cyclone dust removal and desulfurization devices where some dust particles are easily lifted by the airflow, leading to blockage of the air outlet duct over a long period of time.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
