Description

Technical Field

[0001] This utility model specifically relates to the field of waste gas purification technology, and specifically to a waste gas purification tower that can prevent the accumulation of waste gas. Background Technology

[0002] A waste gas purification tower is a device specifically designed to treat industrial waste gas. It uses a series of physical, chemical, and biological methods to purify the waste gas, converting harmful substances into harmless substances, thereby achieving the goals of purifying waste gas, protecting the environment, and safeguarding human health.

[0003] Most current waste gas purification towers utilize the solubility of pollutants in the gas in the liquid or their chemical reaction with the liquid to transfer pollutants from the waste gas to the liquid. For example, acidic waste gas can be absorbed by alkaline liquid, and alkaline waste gas can be absorbed by acidic liquid, achieving an acid-base neutralization reaction and thus removing pollutants from the waste gas.

[0004] However, in practice, it has been noted that many industrial waste gases contain combustible components (such as organic waste gases, volatile organic compounds (VOCs), dust, etc.). When these waste gases accumulate in the purification tower, if the concentration reaches the explosion limit, they can easily cause explosions or fires when exposed to static electricity, sparks, or high temperatures (such as heat sources in catalytic oxidation processes). Furthermore, most waste gas purification towers currently rely solely on intake fans to drive the gas inside the tower for discharge. However, over time, harmful particles can adhere to the internal filtration mechanism, causing the internal gas flow channels to narrow and making it very easy for waste gases to accumulate. The intake fan alone cannot quickly discharge the accumulated waste gas, resulting in a significant risk of contamination. Utility Model Content

[0005] The purpose of this utility model is to provide a waste gas purification tower that can prevent the accumulation of waste gas. The exhaust port features a vortex exhaust mechanism, and the drive structure of the vortex exhaust mechanism is located outside the anti-accumulation mounting pipe. Therefore, when the outer ring of the gear drives the frameless fan blades to rotate, it can guide the waste gas with maximum efficiency, reducing the efficiency of the internal mounting frame in removing waste gas, thereby preventing the accumulation of waste gas inside the waste gas purification tower. This solves the technical problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution:

[0006] An exhaust gas purification tower that can prevent the accumulation of exhaust gas includes an exhaust gas purification tower, an exhaust hood fixedly connected to the top of the exhaust gas purification tower, an anti-accumulation installation pipe fixedly connected to the top of the exhaust hood, and a vortex exhaust mechanism movably connected in the anti-accumulation installation pipe.

[0007] The vortex exhaust mechanism includes an outer gear ring, and the inner side of the outer gear ring is fixedly connected with a frameless fan blade in a ring array.

[0008] As a further technical solution of this utility model, the outer ring of the gear is coupled with a drive gear on its side, and a rotary motor is coupled above the drive gear, and a waterproof cover is fitted above the rotary motor.

[0009] As a further technical solution of this utility model, the anti-gas accumulation installation pipe includes a flange connecting pipe fixedly connected to the gas outlet hood, an integrally provided mounting arc plate on the upper part of the flange connecting pipe, and a rotating motor fixedly connected to the mounting arc plate.

[0010] As a further technical solution of this utility model, the end of the rotary motor extends through the mounting arc plate to the bottom of the mounting arc plate, and the drive gear is located below the mounting arc plate.

[0011] The waterproof cover is fixedly connected to the top of the mounting arc plate.

[0012] As a further technical solution of this utility model, the side of the flange connecting pipe is provided with a through groove, and the side of the drive gear passes through the through groove and meshes with the outer ring of the gear.

[0013] As a further technical solution of this utility model, the inner side of the air outlet hood is fixedly connected with a diversion guide baffle in a ring array, and a cone-shaped air-breaking hood is integrally provided below the diversion guide baffle.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the funnel-shaped exhaust hood, can increase the gas flow speed at the tail of the exhaust hood. Combined with the anti-accumulation installation pipe and vortex exhaust mechanism installed at the tail of the exhaust hood, it can increase the upward guiding force on the exhaust gas, thereby forming a negative pressure adsorption force at the tail of the exhaust hood, which pulls the exhaust gas in the exhaust gas purification tower to flow upward quickly and prevents the exhaust gas from accumulating.

[0016] 2. In this utility model, the transmission between the drive gear and the outer ring of the gear causes the outer ring of the gear to drive the internal frameless fan blades to rotate rapidly. Since the rotating motor is located on the side of the frameless fan blades, compared with ordinary fans, the inner side of the frameless fan blades lacks the obstruction of the supporting frame, making the exhaust gas discharge smoother and preventing some particulate matter in the exhaust gas from sticking to the frame, thus improving the exhaust gas discharge effect.

[0017] 3. This utility model uses an integrated mounting arc plate on the flange connecting pipe to facilitate the installation of the rotary motor. In addition, a waterproof cover is provided on the outside of the rotary motor to protect it and extend its service life. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-5 This utility model provides a waste gas purification tower that can prevent waste gas from accumulating, including a waste gas purification tower 1, an exhaust hood 3 fixedly connected to the top of the waste gas purification tower 1, an anti-accumulation installation pipe 4 fixedly connected to the top of the exhaust hood 3, and a vortex exhaust mechanism 6 movably connected in the anti-accumulation installation pipe 4.

[0027] The vortex exhaust mechanism 6 includes a gear outer ring 61, and the inner side of the gear outer ring 61 is fixedly connected with a frameless fan blade 62 in a ring array.

[0028] By adopting the above technical solution, the gas flow velocity at the tail of the exhaust hood 3 can be increased by the funnel-shaped exhaust hood 3. Combined with the anti-accumulation installation pipe 4 and the vortex exhaust mechanism 6 installed at the tail of the exhaust hood 3, the upward guiding force of the exhaust gas can be increased, thereby forming a negative pressure adsorption force at the tail of the exhaust hood 3, which pulls the exhaust gas in the exhaust gas purification tower to flow upward quickly and prevents the exhaust gas from accumulating.

[0029] Furthermore, the outer ring 61 of the gear is connected to a drive gear 64 on its side, and a rotary motor 63 is connected to the drive gear 64 above it. A waterproof cover 5 is also fitted onto the top of the rotary motor 63.

[0030] Furthermore, the anti-accumulation installation pipe 4 includes a flange connecting pipe 41 fixedly connected to the gas outlet hood 3, and an integrally provided mounting arc plate 43 is provided above the flange connecting pipe 41, and the rotary motor 63 is fixedly connected to the mounting arc plate 43.

[0031] More specifically, the end of the rotary motor 63 extends through the mounting arc plate 43 to the bottom of the mounting arc plate 43, and the drive gear 64 is located below the mounting arc plate 43.

[0032] The waterproof cover 5 is fixedly connected to the upper part of the mounting arc plate 43.

[0033] By adopting the above technical solution, the transmission between the drive gear 64 and the outer ring 61 of the gear causes the outer ring 61 of the gear to drive the internal frameless fan blade 62 to rotate rapidly. Since the rotating motor 63 is located on the side of the frameless fan blade 62, compared with ordinary fans, the inner side of the frameless fan blade 62 lacks the obstruction of the supporting frame, making the exhaust gas discharge smoother and preventing some particulate matter in the exhaust gas from sticking to the frame, thus improving the exhaust gas emission effect.

[0034] Furthermore, the flange connecting pipe 41 has a through groove 42 on its side, and the side of the drive gear 64 passes through the through groove 42 and meshes with the outer ring 61 of the gear.

[0035] Furthermore, the inner side of the air outlet hood 3 is fixedly connected with a diversion guide baffle 31 in a ring array, and a cone-shaped air breaker hood 32 is integrally provided below the diversion guide baffle 31.

[0036] Furthermore, the flange connecting pipe 41 is provided with symmetrical limiting protrusions on its inner side, and the limiting protrusions are respectively engaged with the two sides of the gear outer ring 61, thereby ensuring that the gear outer ring 61 can rotate inside the flange connecting pipe 41.

[0037] Furthermore, the longitudinal section of the exhaust hood 3 is arranged in a trumpet shape, and the airflow velocity is increased through the gradually narrowing pipe, which adsorbs the exhaust gas inside the exhaust gas purification tower 1, thereby improving the emission efficiency of the exhaust gas and preventing the exhaust gas from accumulating inside the exhaust gas purification tower 1.

[0038] The working principle of this utility model is as follows: During use, the exhaust gas is first sent into the inner side of the exhaust gas purification tower 1 by the intake fan 2. The exhaust gas purification tower 1 purifies the exhaust gas. At the same time, through the transmission cooperation between the outer ring of the gear 61 and the drive gear 64, the rotary motor 63 drives the outer ring of the gear 61 to rotate. The outer ring of the gear 61 drives the inner frameless fan blades 62, which are arranged in a ring array, to rotate rapidly. Since the frameless fan blades 62 lack a frame inside, a vortex is formed when the frameless fan blades 62 rotate. Combined with the exhaust hood 3, which is set in a funnel shape, a negative pressure adsorption force is formed above the exhaust hood 3, thereby increasing the exhaust gas flow rate inside the exhaust gas purification tower 1. Furthermore, the exhaust hood 3 is equipped with a diversion guide baffle 31 inside, which divides the internal space of the exhaust hood 3 to ensure rapid airflow and prevent exhaust gas from accumulating inside the exhaust gas purification tower 1. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
