Description

Technical Field

[0001] The utility model relates to the technical field of furfural production, in particular to an environmentally friendly and energy-saving waste gas treatment device for furfural. Background Art

[0002] Furfural is an organic compound, a colorless, transparent, oily liquid with a special smell similar to benzaldehyde. It is mainly used as an industrial solvent and can also be used to prepare furfuryl alcohol, furoic acid, tetrahydrofuran, γ-valerolactone, pyrrole, tetrahydropyrrole, etc.

[0003] Furfural will produce waste gas containing dust impurities during the production process. Generally, the waste gas is washed with water to remove the dust.

[0004] During the washing process, as the dust accumulates in the water and the water gradually becomes turbid, the used water needs to be directed to an external filter structure for filtration, and then new water is introduced. The water circulation of the entire device is not smooth, and a large amount of circulating water is required.

[0005] To this end, we propose a furfural environmentally friendly and energy-saving waste gas treatment device to solve the existing problems. Utility Model Content

[0006] The utility model aims to solve the problems existing in the background technology and proposes an environmentally friendly and energy-saving waste gas treatment device for furfural.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a furfural environmentally friendly and energy-saving waste gas treatment device, comprising a base plate, a tank body, a liquid pump, a sealing plate, a mesh plate, a box body and a reflux pump, wherein a support seat is provided on the lower surface of the base plate, a tank body is provided on the upper surface of the base plate, a suction pipe is provided at the suction end of the liquid pump, the suction pipe and the tank body are connected to each other, the discharge end of the liquid pump and the box body are connected to each other, the suction end of the reflux pump is arranged on the box body, the discharge end of the reflux pump is provided with a reflux pipe, and the reflux pipe and the tank body are connected to each other.

[0008] Preferably, an air inlet pipe is installed at an upper end of one side of the tank body, and an exhaust port is installed at the top opening of the tank body.

[0009] Preferably, the sealing plate is arranged on the box body, a connecting rod is arranged on the lower surface of the sealing plate, a mesh plate is installed on the bottom end of the connecting rod through bolts, and the mesh plate is in sliding contact with the box body.

[0010] Preferably, rubber pads are glued around the lower surface of the sealing plate, the rubber pads are against the upper surface of the box body, and a vibration motor is installed on the upper surface of the sealing plate by bolts.

[0011] Preferably, the discharge end of the liquid suction pump is located above the mesh plate, and the suction end of the reflux pump is located below the mesh plate.

[0012] Preferably, there are four support seats in total, and the positions of the four support seats are distributed in a rectangular array on the lower surface of the base plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. During the use of the environmentally friendly and energy-saving furfural waste gas treatment device of the utility model, the waste gas generated by the furfural production is introduced into the water body inside the tank through the air inlet pipe. Under the action of water washing, impurities are intercepted by the water body, and the clean gas overflows the water surface and is discharged through the discharge port. In this process, the liquid pump works to draw the impurity-containing water body into the box for filtration, and the filtered water re-enters the tank body through the suction of the reflux pump, and the operator only needs to open the box regularly to clean the impurities on the mesh plate. The utility model is convenient for water washing of the waste gas, and the entire device only needs a small amount of water to achieve the efficiency of circulation filtration, which can save the initial water resource investment.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A support seat 2 is provided on the lower surface of the base plate 1, a tank body 4 is provided on the upper surface of the base plate 1, a suction pipe 6 is provided at the suction end of the liquid pump 7, the suction pipe 6 is connected to the tank body 4, the discharge end of the liquid pump 7 is connected to the box body 13, the suction end of the reflux pump 14 is arranged on the box body 13, the discharge end of the reflux pump 14 is provided with a reflux pipe 15, and the reflux pipe 15 and the tank body 4 are connected to each other.

[0021] Based on Example 1: the waste gas generated by furfural production is introduced into the water body inside the tank body 4 through the air inlet pipe 3. Under the action of water washing, impurities are intercepted by the water body, and the clean gas overflows the water surface and is discharged through the discharge port 5. In this process, the liquid pump 7 works to draw the impure water body into the box body 13 for filtration, and the filtered water re-enters the tank body 4 through the suction of the reflux pump 14, and the operator only needs to open the box body 13 regularly to clean the impurities on the mesh plate 12.

[0022] Embodiment 2

[0023] like Figure 1-2 As shown, the utility model proposes an environmentally friendly and energy-saving furfural waste gas treatment device. Compared with the first embodiment, this embodiment also includes: an air inlet pipe 3 is installed at the upper end of one side of the tank body 4, and an exhaust port 5 is installed at the top opening of the tank body 4. Through the cooperation of the above structures, the waste gas generated by the furfural production is introduced into the water body inside the tank body 4 through the air inlet pipe 3, and the clean gas overflows the water surface and is discharged through the exhaust port 5.

[0024] A sealing plate 8 is arranged on a box body 13, and a connecting rod 11 is arranged on the lower surface of the sealing plate 8. A mesh plate 12 is installed at the bottom end of the connecting rod 11 by bolts. The mesh plate 12 is in sliding contact with the box body 13.

A vibration motor 9 is installed on the upper surface of the sealing plate 8 by bolts. The discharge end of the liquid pump 7 is above the mesh plate 12.

In this process, the vibration motor 9 can be controlled to drive the mesh plate 12 to vibrate. Under the action of vibration, water is accelerated to pass through the mesh plate 12, thereby increasing the filtration speed. The suction end of the reflux pump 14 is below the mesh plate 12, which ensures that the reflux pump 14 sucks the treated water and re-enters the tank body 4.

[0025] There are four support bases 2 in total, and the positions of the four support bases 2 are distributed in a rectangular array on the lower surface of the base plate 1 .
