Description

Technical Field

[0001] The utility model relates to the technical field of furfural production equipment, in particular to a gas-water separation device for a furfural production line. Background Art

[0002] Furfural is a green biomass product. It is produced by hydrolyzing high-polymer bran in plant fiber raw materials into pentose under a certain temperature and catalyst, and then dehydrating the pentose to generate furfural. The furfural production process includes raw material processing, hydrolysis, distillation, neutralization, and refining. During the distillation process, impurities are removed to obtain an azeotrope of aldehyde and water. Then, the water and aldehyde gas in the azeotrope need to be separated to remove the water in furfural and facilitate the refining of furfural. However, the current gas-water separation device has a low separation efficiency and the separation result is not ideal, resulting in the aldehyde gas drawn out after separation still containing a high amount of water, which may affect the quality of subsequent furfural products. At the same time, the aldehyde gas containing water entering the next process may cause equipment blockage. Utility Model Content

[0006] The above-mentioned gas-water separation device for furfural production line is provided with a one-way valve on the air inlet pipe to prevent the water vapor in the separation box from being discharged along with the aldehyde gas.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0017] A gas-water separation device for a furfural production line, such as Figures 1 to 4 As shown, it includes a separation box 1, the bottom of which is connected to the air inlet pipe 2, the top of which is provided with an air outlet 8, and the top of the separation box 1 is connected to the air outlet pipe 3, the bottom of the separation box 1 is provided with a drain port 7, and water-dividing plates 5 for absorbing moisture are installed in sequence in a staggered manner inside the separation box 1.

[0018] The water-dividing plate 5 is a corrugated plate, which can delay the diffusion time of the gas in the aldehyde-water azeotrope, so that the water vapor therein can be adsorbed on the water-dividing plate 5 as much as possible. At the same time, multiple staggered water-dividing plates 5 are arranged to gradually adsorb and filter the water vapor in the aldehyde-water azeotrope, so that the water content in the aldehyde gas finally separated is gradually reduced.

[0019] A horizontal connecting plate 10 is provided on one side of the water dividing plate 5. Figure 3 As shown, the connecting plate 10 is connected to the handle 6 passing through the separation box body. By rotating the handle 6, the water distribution plate 5 is adjusted to a vertical position, so that the adsorbed water vapor can be discharged through the drain port 7 at the bottom of the separation box 1.

[0020] A fan 9 is also provided at the top of the separation box 1. After all the aldehyde gas is led out, the water dividing plate 5 is adjusted to a vertical position, and the fan 9 can be started to blow off the water vapor adsorbed on the water dividing plate 5.

[0021] A one-way valve 4 is provided on the air inlet pipe 3. Closing the one-way valve 4 after the aldehyde gas is led out can prevent the water vapor inside the separation box 1 from being discharged along with the aldehyde gas.

[0022] A drying component is provided inside the air intake pipe 2, and the drying component includes air permeable plates 11 installed in sequence inside the air intake pipe 2, with a certain gap between the air permeable plates 11, and a drying bag 12 filled with a desiccant is installed on the air permeable plate 11, which can absorb the residual moisture inside the aldehyde gas drawn out. The drying bag 12 can be replaced by simply removing the air permeable plate.

[0023] When in use, the one-way valve 4 is opened to ensure that the aldehyde gas can flow along the air outlet 8 to the air outlet pipe 3, and the gas flows along the water dividing plate 5, so that the water vapor is adsorbed on the water dividing plate 5, and the aldehyde gas is discharged upward. The discharged aldehyde gas passes through the drying component and the residual moisture in the aldehyde gas is adsorbed by the drying bag 12 until the aldehyde gas is completely discharged, and then the one-way valve 4 is closed.

[0024] Then, the handle 6 is turned to rotate the water distribution plate 5 to a vertical position, and at the same time, the fan 9 is turned on to blow off the water vapor on the water distribution plate 5 and discharge it through the drain port 7.

[0025] The utility model provides a gas-water separation device for a furfural production line, which slows down the flow rate of the aldehyde-water azeotrope in a separation box by arranging a plurality of corrugated water-dividing plates staggered up and down, so that water vapor is adsorbed on the water-dividing plates, and a drying component is arranged at the water inlet pipe to ensure that the water vapor discharged with the aldehyde gas can be adsorbed on the desiccant, effectively removing the moisture in the aldehyde gas and ensuring the quality of the furfural product finally produced.
