Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a furfural production waste gas treatment device. Background Technology

[0002] Furfural is an important organic chemical raw material widely used in pesticides, pharmaceuticals, dyes, and other fields. However, the production of furfural generates a large amount of waste gas, containing organic compounds such as furfural, methanol, and acetaldehyde, as well as small amounts of sulfides and nitrogen oxides. If this waste gas is discharged directly without treatment, it will cause serious environmental pollution and harm human health. Therefore, the waste gas needs to be treated to meet emission standards before being released. In addition to washing and purification, furfural waste gas treatment also requires filtration and adsorption, which are typically performed by a single device.

[0003] In existing waste gas filtration and adsorption devices, filter screens are used to filter larger particulate matter, while adsorption plates are used to remove small particulate matter such as odors from the waste gas. In these devices, small particles are difficult to detach after adsorption, so the adsorption plates need to be replaced regularly. Larger particles, however, can detach and are typically recycled by cleaning the filter screen, ensuring its reuse. However, cleaning the filter screen requires disassembling and removing it each time, which is extremely complicated. Furthermore, the waste gas flow must be stopped during the cleaning process, causing the entire device to shut down and affecting the rapid treatment of waste gas, resulting in generally poor performance. Utility Model Content

[0004] The main objective of this invention is to provide a furfural production waste gas treatment device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A furfural production waste gas treatment device includes a main body, a dust hopper installed at the lower end of the main body, a filter screen frame inside the main body, an elastic vibrating plate at the upper end of the filter screen frame, a striking structure at the top of the main body, and an activated carbon adsorption plate inside the main body.

[0007] Preferably, the top of the main body of the device is provided with a fixing seat, the upper end of the activated carbon adsorption plate passes through the main body of the device and the fixing seat, and the upper end of the activated carbon adsorption plate is provided with a mounting plate.

[0008] Preferably, the upper end of the filter screen frame extends through the main body of the device, and a handle is fixed to the upper end of the filter screen frame; a pressure plate is provided on the top of the main body of the device.

[0009] Preferably, the lower end of the dust hopper is provided with a sealing plate, and the elastic vibrating plate is arranged in an inverted L-shape at the upper end of the filter frame.

[0010] Preferably, an air inlet flange is fixed at one end of the main body of the device, and an exhaust flange is provided at the other end of the main body of the device.

[0011] Preferably, the striking structure includes a geared motor, a drive wheel, a bracket, a rotating shaft, a circular plate, a striking rod, a driven wheel, and a belt. The geared motor is fixed to the top of the main body of the device. The drive wheel is mounted on the output shaft of the geared motor. The bracket is fixed to the main body of the device. The rotating shaft is fixedly connected to the circular plate and is mounted on the bracket. The striking rod is fixed to the circular plate. The driven wheel is mounted on the end of the rotating shaft. The belt is sleeved on the drive wheel and the driven wheel.

[0012] Compared with the prior art, this utility model has the following beneficial effects: This furfural production waste gas treatment device, by installing an elastic vibrating plate on the upper end of the filter screen frame, transmits the effect of vibration to the filter screen frame, thereby shaking large particles on the filter screen frame to the dust hopper. Cleaning can be achieved without disassembling and removing the filter screen frame, and without interrupting the use of the device, ensuring the efficiency of the device. The device adopts a striking structure, using a geared motor to drive a smaller driving wheel to rotate, which in turn drives the shaft to rotate through a belt and a larger driven wheel, thereby slowly rotating the circular plate and striking rod. This allows the striking rod to periodically strike the elastic vibrating plate, ensuring the vibration effect on large particles. At the same time, within each cycle, the striking rod rotates to make way after striking the elastic vibrating plate, without affecting the vibration of the elastic vibrating plate, thus ensuring the vibration effect.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, a furfural production waste gas treatment device includes a main body 1, a dust hopper 2 installed at the lower end of the main body 1, a filter frame 3 inside the main body 1, an elastic vibrating plate 4 at the upper end of the filter frame 3, a striking structure 5 at the top of the main body 1, and an activated carbon adsorption plate 7 inside the main body 1. A fixing seat 6 is provided at the top of the main body 1, the upper end of the activated carbon adsorption plate 7 passes through the main body 1 and the fixing seat 6, and an mounting plate 8 is provided at the upper end of the activated carbon adsorption plate 7.

[0020] The upper end of the filter frame 3 extends through the main body 1 of the device, and a handle 12 is fixed to the upper end of the filter frame 3. A pressure plate 11 is provided on the top of the main body 1 of the device. A sealing plate 13 is provided at the lower end of the dust hopper 2. An inverted L-shaped elastic vibration plate 4 is provided at the upper end of the filter frame 3. An air inlet flange 9 is fixed at one end of the main body 1 of the device, and an exhaust flange 10 is provided at the other end of the main body 1 of the device.

[0021] During furfural production, the generated waste gas is transported to the main body 1 of the device through a pipe connected to the inlet flange 9. After being filtered by the filter frame 3, the waste gas is further adsorbed by the activated carbon adsorption plate 7 for small particulate matter, thus achieving multi-stage purification of the waste gas. The treated waste gas is then transported through a pipe at the exhaust flange 10. Throughout the waste gas treatment process, the striking structure 5 periodically strikes the inverted L-shaped elastic vibrating plate 4. The vibrating plate 4 vibrates and transmits its effect to the filter frame 3, causing large particles to fall into the dust collection hopper 2, preventing the accumulation of large particles on the filter frame 3 and thus avoiding obstruction of gas flow. After the device has been used for a period of time, the sealing plate 13 can be opened to discharge large particles. Simultaneously, the screws on the mounting plate 8 can be removed to remove and replace the activated carbon adsorption plate 7, ensuring adsorption efficiency. If necessary, the pressure plate 11 can be removed to detach the filter frame 3 from the main body 1 for replacement. The structure is simple and the operation is convenient and quick.

[0022] According to the above implementation scheme, the striking structure 5 includes a reduction motor 501, a drive wheel 502, a bracket 503, a rotating shaft 504, a circular plate 505, a striking rod 506, a driven wheel 507, and a belt 508. The reduction motor 501 is fixed to the top of the device body 1, the drive wheel 502 is mounted on the output shaft of the reduction motor 501, the bracket 503 is fixed to the device body 1, the rotating shaft 504 is fixedly connected to the circular plate 505 and is mounted on the bracket 503, the striking rod 506 is fixed on the circular plate 505, the driven wheel 507 is mounted on the end of the rotating shaft 504, and the belt 508 is sleeved on the drive wheel 502 and the driven wheel 507.

[0023] When the elastic vibrating plate 4 is struck, the reduction motor 501 is started. The reduction motor 501 drives the drive wheel 502 to rotate through the output shaft. Driven by the belt 508, the driven wheel 507 rotates slowly, thus causing the rotating shaft 504 to rotate on the bracket 503. During the rotation of the rotating shaft 504, the circular plate 505 rotates with the striking rod 506. When the striking rod 506 contacts the elastic vibrating plate 4, the elastic vibrating plate 4 deforms. When the striking rod 506 leaves the elastic vibrating plate 4, the elastic vibrating plate 4 vibrates due to its elasticity. The vibration is transmitted to the filter screen frame 3, which can shake large particles on the filter screen frame 3 into the dust collection hopper 2. The purpose of cleaning can be achieved without removing the filter screen frame 3. As the striking structure 5 operates, the circular plate 505 rotates periodically with the striking rod 506, thus periodically striking the elastic vibrating plate 4. After the striking rod 506 leaves the elastic vibrating plate 4, the vibration of the elastic vibrating plate 4 is not affected, ensuring the vibration effect.

[0024] It should be noted that by installing an elastic vibrating plate 4 on the upper end of the filter screen frame 3, the effect of the vibration plate 4 is transmitted to the filter screen frame 3, thereby shaking large particles on the filter screen frame 3 into the dust hopper 2. Cleaning can be achieved without disassembling and removing the filter screen frame 3, and without interrupting the use of the device, ensuring the efficiency of the device. The striking structure 5 is adopted, using a reduction motor 501 to drive the smaller driving wheel 502 to rotate, which in turn drives the rotating shaft 504 to rotate through the belt 508 and the larger driven wheel 507. This causes the circular plate 505 and the striking rod 506 to rotate slowly, so that the striking rod 506 can periodically strike the elastic vibrating plate 4, ensuring the vibration effect on large particles. At the same time, in each cycle, the striking rod 506 rotates to make way after striking the elastic vibrating plate 4, without affecting the vibration of the elastic vibrating plate 4, thus ensuring the vibration effect.
