Description

Technical Field

[0001] This invention relates to a device and method for treating alcohol precipitate powder solids obtained from the epoxy extraction of brewing sludge, belonging to the field of solid waste treatment technology. Background Technology

[0002] During the brewing process, the sludge from the sedimentation fermentation process spontaneously and actively releases saccharified sediment, which is then concentrated and finely processed under high-temperature pressing conditions for catalytic reaction. After the alcohol is produced, the saccharified sediment accumulates at the bottom, while the upper lees can be used as animal feed and modified agricultural materials. The remainder is brewing sludge, also known as rotten sludge. The accumulation of this industrial solid waste is a historical problem. The solidified, plate-like material is inactive, and the aggregated, blocky material lacks pores, making it unsuitable for plant growth and survival. This has led to difficulties in the treatment of the solid waste. Over time, the accumulated deposits have grown, the hazards of the solid waste have increased, the treatment problems have intensified, and the technical challenges have become prominent. Summary of the Invention

[0003] To address the technical problems existing in the prior art, this invention provides a simple and convenient device and method for treating alcohol precipitate powder solids from brewing sludge through epoxy extraction, which can recycle sludge and improve waste utilization.

[0004] To achieve the above objectives, the technical solution adopted by this invention is a treatment device for alcohol precipitate powder solids obtained from the epoxy extraction of brewing sludge. The device includes a storage hopper, a first screw conveyor installed at the bottom of the storage hopper, the first screw conveyor being vertically arranged, a discharge pipe at the lower part of the first screw conveyor connected to the inlet pipe of a second screw conveyor, the discharge pipe of the second screw conveyor connected to a sterilization storage tank, a water spray pipe installed on the upper circumference of the storage hopper, multiple high-temperature steam pipes installed on the first screw conveyor, a filter chamber at the bottom of the first screw conveyor, a filter plate at the upper part of the filter chamber, a condenser pipe connected to the filter chamber, the condenser pipe connected to a condenser tank, a sedimentation tank connected to the bottom of the condenser tank, multiple oxygen injection pipes installed on the second screw conveyor, and a stirring shaft connected to the rotating shaft of the first screw conveyor extending into the storage hopper.

[0005] Preferably, both the first and second screw conveyors are made of high-temperature resistant and corrosion-resistant materials.

[0006] Preferably, an annular dust collection hood is installed on the top circumference of the storage hopper, and a negative pressure suction pipe for connecting to a dust collector is connected to the annular dust collection hood.

[0007] A method for treating alcohol precipitate powder solids from brewing sludge obtained through epoxy extraction comprises the following steps: a. Add the sludge to the storage hopper and stir and spray it to completely loosen the sludge. b. The loosened mud enters the first screw conveyor and is catalyzed by high-temperature steam to gelatinize the starch in the mud. It is then filtered into the filter chamber along with the spray water and steam water. After condensation and sedimentation, the supernatant is used for irrigation. c. The remaining mud is transported by the second screw conveyor and oxygenated air is injected through the oxygen injection pipe. After the mud comes into full contact with the air, it is sent to the sterilization tank for disinfection and then used for the compounding and improvement of ecological filler.

[0008] Compared with the prior art, the present invention has the following technical effects: The present invention uses a spraying method combined with steam heating to gelatinize the starch in the sludge, and then recovers it to the sedimentation tank after filtration, condensation and sedimentation; the remaining sludge is oxygenated to restore its activity, and after sterilization treatment, it can meet the requirements as a filler for ecological planting, thereby achieving the harmless treatment of sludge. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of the present invention. Detailed Implementation

[0010] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0011] like Figure 1 As shown, a treatment device for alcohol precipitate powder solids from brewing sludge epoxy extraction includes a storage hopper 1, a first screw conveyor 2 installed at the bottom of the storage hopper 1, the first screw conveyor 2 being vertically arranged, a discharge pipe 3 at the lower part of the first screw conveyor 2 being connected to the feed pipe of a second screw conveyor 4, the discharge pipe of the second screw conveyor 4 being connected to a sterilization storage tank 5, a water spray pipe 6 installed on the upper circumference of the storage hopper 1, multiple high-temperature steam pipes 7 installed on the first screw conveyor 2, a filter chamber 8 at the bottom of the first screw conveyor 2, a filter plate 9 installed on the upper part of the filter chamber 8, a condenser pipe 10 connected to the filter chamber 8, the condenser pipe 10 being connected to a condenser tank 11, a sedimentation tank 16 connected to the bottom of the condenser tank 11, multiple oxygen injection air pipes 12 installed on the second screw conveyor 4, and a stirring shaft 13 connected to the rotating shaft of the first screw conveyor 2, the stirring shaft 13 extending into the storage hopper 1.

[0012] This invention involves placing sludge in a storage hopper 1, then stirring it with a stirring shaft 13 and spraying it with water from a spray pipe 6 to quickly break up and moisten the hardened sludge. Then, as the first screw conveyor 2 rotates, the sludge slowly enters the hopper. Because the first screw conveyor 2 operates at a relatively low speed (25-30 revolutions per minute) and is 3-5 meters long, the sludge has sufficient residence time within it. This allows for further rapid gelatinization of the starch in the sludge when high-temperature steam is injected through the high-temperature steam pipe 7. The starch, sprayed water, and steam then flow to the bottom of the first screw conveyor 2, are filtered through a filter plate 9, and enter a condenser 11. Finally, the sludge enters a sedimentation tank 16 for sedimentation and separation. The supernatant can be used for irrigation. The sludge then enters the second screw conveyor 4 through the discharge pipe 3. The second screw conveyor 4 rotates at a relatively high speed, 50-60 revolutions per minute, and is 3 meters long. During this process, the oxygen injection pipe 12 injects oxygen-containing air into the sludge, allowing the sludge to mix thoroughly with the air and regain its activity. It is then sent to the sterilization storage tank 5 for sterilization treatment. After treatment, it can be used for the compounding and improvement of ecological fillers.

[0013] Both the first screw conveyor 2 and the second screw conveyor 4 are made of high-temperature and corrosion-resistant materials. An annular dust collection hood 14 is installed on the top circumference of the storage hopper 1, and a negative pressure suction pipe 15 is connected to the annular dust collection hood 14 for connection to a dust collector. The annular dust collection hood 14 adsorbs dust from the hardened sludge, preventing dust from overflowing.

[0014] In practical use, please follow these steps: a. Add the sludge to the storage hopper and stir and spray it to completely loosen the sludge. b. The loosened mud enters the first screw conveyor and is catalyzed by high-temperature steam to gelatinize the starch in the mud. It is then filtered into the filter chamber along with the spray water and steam water. After condensation and sedimentation, the supernatant is used for irrigation. c. The remaining mud is transported by the second screw conveyor and oxygenated air is injected through the oxygen injection pipe. After the mud comes into full contact with the air, it is sent to the sterilization tank for disinfection and then used for the compounding and improvement of ecological filler.

[0015] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
