Description

Technical Field

[0001] The utility model relates to a vertical Venturi device. Background Art

[0002] In the process of industrial production, gas emissions are often accompanied by the release of solid particles such as dust. These particles not only pollute the environment but may also pose hazards to human health.

[0003] Most traditional dust treatment devices use Venturi devices for treatment. However, traditional Venturi devices use spray pipes to adsorb and reduce dust in the gas in terms of structure, which is likely to cause certain losses to the pressure and flow rate of the gas during the spraying process, thereby affecting the dust reduction effect of the gas. Therefore, a vertical Venturi device is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a vertical Venturi device to solve the problem that traditional Venturi devices use spray pipes to adsorb and reduce dust in the gas in terms of structure, which is likely to cause losses to the pressure and flow rate of the gas during the spraying process as mentioned in the above background art.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A vertical Venturi device includes a Venturi tube, which is successively provided with an air inlet part, an adsorption part, and a diffusion part from top to bottom. An air outlet pipe is arranged beside the diffusion part of the Venturi tube;

[0006] The Venturi tube is provided with an atomizing member at the adsorption part,

[0007] Among them, the Venturi tube adsorbs and aggregates dust in the gas through the atomizing member.

[0008] Preferably, the air inlet part includes a connecting flange at the top end of the Venturi tube. A converging tube is connected below the connecting flange, and the top end of the converging tube is circular while the bottom end is rectangular.

[0009] Preferably, bearing platforms for connecting the atomizing member are arranged on both sides of the adsorption part, and the included angle between the bearing platform and the Y-axis is 30°.

[0010] Preferably, the atomizing member includes a flange plate beside the adsorption part. Pump water branch pipes are arranged on both sides of the flange plate. Multiple groups of spray pipes are arranged at the pump water branch pipes, and nozzles are arranged at one ends of the multiple groups of spray pipes far away from the pump water branch pipes.

[0011] Preferably, the included angle between the spray pipe and the Y-axis is 30°, and the shape of the spray pipe is "L" shaped.

[0012] Preferably, a necking baffle is provided inside the adsorption part, and the included angle between the baffle of the necking baffle and the inner wall of the adsorption part is 19°.

[0013] Preferably, a discharge pipe for discharging dust is provided at the bottom end of the Venturi tube located in the diffusion part.

[0014] Preferably, the adsorption part and the diffusion part are rectangular in shape.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] By arranging an atomizing member in the adsorption part, the present utility model can more effectively adsorb and coagulate dust in the gas, thereby improving the efficiency of dust treatment.

[0017] In the traditional Venturi device, pressure and flow rate losses may occur during the spraying process. The included angle between the spray pipe of the atomizing member of this device and the Y-axis is 30°, and the shape of the spray pipe is "L" shaped. Compared with the traditional spray pipe, it can spray water mist along the air flow direction through the nozzle, effectively reducing pressure loss, further improving the adsorption and dust removal effects of dust, and thus improving the dust removal effect.

[0018] The design of the converging pipe in the air inlet part (round at the top and rectangular at the bottom) and the design of the included angle between the bearing platform of the adsorption part and the Y-axis (30°) help to improve the uniformity of gas flow and the effect of dust adsorption.

[0019] By providing a dust discharge pipe at the bottom end of the diffusion part, dust can be effectively discharged, avoiding the accumulation of dust inside the device and affecting the operating efficiency of the device.

[0020] The rectangular shape design of the adsorption part and the diffusion part helps to simplify the device structure and is convenient for manufacturing and maintenance. Description of the Drawings

[0024] In order to facilitate the solution of the problem that in the traditional Venturi device, when the dust in the gas is adsorbed and dust-removed by using a spray pipe in the structure, the pressure and flow rate of the gas are easily lost during the spraying process, the embodiment of the present utility model provides a vertical Venturi device. The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-2 , the present utility model provides a vertical Venturi device, including a Venturi tube 1, the Venturi tube 1 is sequentially provided with an air inlet part 101, an adsorption part 102, and a diffusion part 103 from top to bottom, and an air outlet pipe 2 is arranged beside the diffusion part 103 of the Venturi tube 1;

[0026] The Venturi tube 1 is provided with an atomizing part 3 at the adsorption part 102. The atomizing part 3 includes a flange plate 301 beside the adsorption part 102. Both sides of the flange plate 301 are provided with pump water branch pipes 302. Multiple groups of spray pipes 303 are arranged at the pump water branch pipes 302. One end of multiple groups of the spray pipes 303 far from the pump water branch pipes 302 is provided with nozzles 304. The included angle between the spray pipe 303 and the Y-axis is 30°, and the shape of the spray pipe 303 is in the shape of "L".

[0027] Among them, the Venturi tube 1 adsorbs and aggregates the dust in the gas through the atomizing part 3.

[0028] The air inlet part 101 includes a connection flange 1011 at the top end of the Venturi tube 1. A contraction pipe 1012 is connected below the connection flange 1011. The top end of the contraction pipe 1012 is circular, and the bottom end of the contraction pipe 1012 is rectangular.

[0029] Both sides of the adsorption part 102 are provided with a bearing platform 1021 for connecting the atomizing part 3, and the included angle between the bearing platform 1021 and the Y-axis is 30°.

[0030] A necking baffle 305 is arranged inside the adsorption part 102, and the included angle between the baffle of the necking baffle and the inner wall of the adsorption part 102 is 19°.

[0031] The Venturi tube 1 is provided with a discharge pipe 4 for discharging dust at the bottom end of the diffusion part 103.

[0032] The shapes of the adsorption part 102 and the diffusion part 103 are rectangular.

[0033] The working principle of the vertical venturi device provided by this utility model is as follows: gas enters from the inlet of the venturi tube 1, and a small portion is discharged through the outlet tube 4 with a very small cross section.

[0034] The gas is introduced along the condensation tube 1012. The cross-section of the condensation tube 1012 gradually decreases, the pressure of the compressed air decreases, and the flow rate increases. At this time, a vacuum is generated in the inlet of the adsorption section 102, causing the surrounding air to be drawn into the adsorption section 102. Water is sprayed into the interior using the nozzle 304, which can effectively remove dust and other particles from the gas.

[0035] Then, along with the compressed air, it flows into the diffusion chamber to reduce the gas flow rate.

[0036] When the gas passes through the constricted baffle 305, the Venturi effect creates a vacuum area at the rear end of the baffle, thereby opening the water column and forming a water curtain effect, allowing the dust to come into full contact with the water curtain, thus improving the dust removal efficiency.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
