Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically to a waste liquid treatment device for furfuryl alcohol production. Background Technology

[0002] Furfuryl alcohol is an important organic chemical raw material, a colorless to pale yellow transparent liquid with a special odor and bitter taste. It is mainly used to prepare furan resins, and can also be used as a solvent, dispersant, and wetting agent for dyes, varnishes, phenolic resins, and furan resins. During the production of furfuryl alcohol, wastewater is inevitably generated. Furfuryl alcohol wastewater is a high-concentration organic wastewater containing abundant nutrients. Anaerobic digestion is one of the effective methods for treating this type of high-concentration organic wastewater. The equipment used in anaerobic digestion is an anaerobic biological filter, whose basic structure includes a sealed tank and internal packing material. However, impurities in the wastewater can clog the packing material during use. Therefore, it is necessary to design a wastewater treatment device for furfuryl alcohol production that reduces packing material clogging. Utility Model Content

[0003] The purpose of this invention is to provide a waste liquid treatment device for furfuryl alcohol production, which has the advantage of reducing packing blockage.

[0004] The technical solution adopted is as follows:

[0005] A waste liquid treatment device for furfuryl alcohol production includes a sealed tank, a water distribution mechanism, a packing layer, and a spraying mechanism. An exhaust mechanism is installed at the upper end of the sealed tank, and a drain valve is installed at the lower end of the sealed tank.

[0006] The packing layer is located in the middle of the sealed pool body.

[0007] The packing layer includes a fixed packing layer and a vertically sliding moving packing layer, with the fixed and moving packing layers staggered.

[0008] A frame is installed above the packing layer, and several water inlet pipes and several spray pipes are horizontally arranged on the frame. Each water inlet pipe has several water outlet holes at its lower end.

[0009] Several high-pressure nozzles are installed below each spray pipe.

[0010] Preferably, the upper end of the sealed pool is provided with a winch mechanism, which includes several synchronously lifting steel cables, and the steel cables are connected to the moving filler layer below.

[0011] Preferably, the lower end of the sealed pool is inverted trapezoidal, and a drain trough is provided at the lower end of the sealed pool. The drain trough is connected to a discharge valve, and a pusher screw is rotatably installed inside the drain trough.

[0012] Preferably, the moving packing layer is provided with a limit switch for positioning the moving packing layer.

[0013] Preferably, electric heating wires are pre-embedded at the bottom and sides of the sealed pool.

[0014] Compared to existing technologies, the advantages are:

[0015] 1. In the anaerobic treatment process, the moving packing layer is joined with the fixed packing layer to carry out the anaerobic reaction. During the water distribution process, the moving packing layer is lifted to separate the moving packing layer from the fixed packing layer, thereby reducing the blockage of the packing by impurities.

[0016] 2. This utility model utilizes high-pressure spraying to flush the moving and stationary packing layers with high-pressure water, thereby reducing the adhesion of impurities and reducing packing blockage.

[0017] 3. In this utility model, the impurities at the bottom of the sealed tank are discharged from the discharge valve under the action of the pusher screw. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown:

[0023] Example 1: A waste liquid treatment device for furfuryl alcohol production includes a sealed tank 1, a water distribution mechanism 2, a packing layer and a spraying mechanism. An exhaust mechanism is provided at the upper end of the sealed tank 1 to discharge biogas generated by anaerobic reaction in the sealed tank 1. A drain valve is provided at the lower end of the sealed tank 1 to discharge furfuryl alcohol waste liquid and impurity precipitates after anaerobic treatment.

[0024] The packing layer is located in the middle of the sealed tank 1. The packing layer is the reaction site of anaerobic bacteria and furfuryl alcohol waste liquid. The packing layer includes a fixed packing layer 4 and a vertically sliding moving packing layer 3. The fixed packing layer 4 and the moving packing layer 3 are staggered. The combination and separation of the fixed packing layer 4 and the moving packing layer 3 can be achieved by controlling the installation height of the moving packing layer 3.

[0025] A frame 8 is installed above the packing layer. Several water inlet pipes 9 and several spray pipes 10 are horizontally arranged on the frame 8. Several water outlet holes are provided at the lower end of each water inlet pipe 9. Several high-pressure nozzles are provided below each spray pipe 10. A main pipe 12 connected to the water inlet pipes 9 and a high-pressure water supply unit 11 connected to each spray pipe 10 are provided on the outside of the sealed tank body 1.

[0026] During anaerobic treatment, the moving packing layer 3 is joined with the fixed packing layer 4 to carry out the anaerobic reaction. During the water distribution process, the moving packing layer 3 is lifted to separate it from the fixed packing layer 4, reducing the blockage of the packing by impurities. High-pressure spraying is used to flush the moving packing layer 3 and the fixed packing layer 4 with high-pressure water, thereby reducing the adhesion of impurities and reducing the blockage of the packing.

[0027] Example 2: A waste liquid treatment device for furfuryl alcohol production includes a sealed tank 1, a water distribution mechanism 2, a packing layer, and a spraying mechanism. An exhaust mechanism is provided at the upper end of the sealed tank 1 to discharge biogas generated by anaerobic reaction in the sealed tank 1. A drain valve is provided at the lower end of the sealed tank 1 to discharge furfuryl alcohol waste liquid and impurity precipitates after anaerobic treatment. Electric heating wires are pre-embedded at the bottom and sides of the sealed tank 1 to heat the furfuryl alcohol waste liquid in the sealed tank 1 during cold seasons to maintain a good anaerobic reaction rate.

[0028] The packing layer is located in the middle of the sealed tank 1. The packing layer is the reaction site for anaerobic bacteria and furfuryl alcohol waste liquid. The packing layer includes a fixed packing layer 4 and a vertically sliding moving packing layer 3. The fixed packing layer 4 and the moving packing layer 3 are staggered. The combination and separation of the fixed packing layer 4 and the moving packing layer 3 can be achieved by controlling the installation height of the moving packing layer 3. A hoisting mechanism 6 is provided at the upper end of the sealed tank 1. The hoisting mechanism 6 includes several synchronously lifting steel cables 7. The steel cables 7 are connected to the moving packing layer 3 below. The moving packing layer 3 is equipped with a limit switch for positioning the position of the moving packing layer 3.

[0029] A frame 8 is installed above the packing layer. Several water inlet pipes 9 and several spray pipes 10 are horizontally arranged on the frame 8. Several water outlet holes are provided at the lower end of each water inlet pipe 9. Several high-pressure nozzles are provided below each spray pipe 10. A main pipe 12 connected to the water inlet pipes 9 and a high-pressure water supply unit 11 connected to each spray pipe 10 are provided on the outside of the sealed tank body 1.

[0030] The lower end of the sealed tank body 1 is inverted trapezoidal. A sludge discharge trough 13 is provided at the lower end of the sealed tank body 1. The sludge discharge trough 13 is connected to the discharge valve 15. A pusher screw 14 is rotatably installed inside the sludge discharge trough 13. The impurities at the bottom of the sealed tank body 1 are discharged from the discharge valve 15 under the action of the pusher screw 14.

[0031] The working principle is as follows:

[0032] During the water distribution process, the moving packing layer 3 is lifted to separate it from the fixed packing layer 4. The furfuryl alcohol waste liquid is then transported to the water distribution mechanism 2 through the main pipe 12. The water distribution mechanism 2 evenly distributes the furfuryl alcohol waste liquid inside the sealed tank 1. During anaerobic treatment, the hoisting mechanism 6 is controlled to connect the moving packing layer 3 and the fixed packing layer 4 to carry out the anaerobic reaction, reducing the blockage of the packing by impurities during the distribution process. After the anaerobic reaction is completed, the waste liquid and impurities are discharged through the discharge valve 15. The high-pressure spray is then activated to flush the moving packing layer 3 and the fixed packing layer 4 with high-pressure water, thereby reducing the adhesion of impurities and reducing the blockage of the packing.
