Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1 , the embodiment of the utility model provides a technical solution: an environmentally friendly and energy-saving alkali solution purification and recovery system device, including an inclined tube sedimentation tank 1, a self-cleaning filter 2, an oil removal tank 3, a bag filter 4, an oblique-mouth tank 5, a slag discharger 6, a collection vehicle 7, a liquid supply pump 8, an alkali mist recovery system 9, a piping system 10, a compressed air system 11, a steel structure platform 12 and an electronic control system 13, wherein the inclined tube sedimentation tank 1, the self-cleaning filter 2, the oil removal tank 3, the bag filter 4, the oblique-mouth tank 5, the slag discharger 6, the collection vehicle 7, the liquid supply pump 8, the alkali mist recovery system 9, the piping system 10, the compressed air system 11 and the electronic control system 13 are all installed in the steel structure platform 12;

[0018] The bottom of the inclined tube sedimentation tank 1 is connected to the inclined mouth tank 5, and the side of the inclined tube sedimentation tank 1 is connected to the liquid supply pump 8 and the bag filter 4 through a pipeline. The upper end of the inclined mouth tank 5 is connected to the inclined tube sedimentation tank 1, and the other end is connected to the slag discharger 6. One end of the self-cleaning filter 2 is connected to the liquid supply pump 8 through the pipeline system 10, and the other end is connected to the bag filter 4 through the pipeline system 10. One end of the side of the degreasing tank 3 is connected to the liquid supply pump 8 through the pipeline system 10, and the other end is connected to the pipeline system 10. The bag filter 4 is connected to the inclined tube sedimentation tank 1 through the pipeline system 10, and the other end is connected to the inclined mouth tank 5, the bag filter 4 is connected to the compressed air system 11 on the side, the upper end of the slag discharger 6 is connected to the inclined trough 5, and the lower end is suspended above the collection vehicle 7, which is arranged below the slag discharger 6. One end of the liquid supply pump 8 is connected to the inclined tube sedimentation tank 1, and the alkali mist recovery system 9 is connected to the inclined tube sedimentation tank 1. The piping system 10 is connected to the liquid supply pump 8, and one end of the compressed air system 11 is connected to the bag filter 4. The inclined tube sedimentation tank 1 uses the principle of shallow flow to precipitate impurities such as iron powder in the alkali solution to the bottom of the tank body, which is used for purification, recovery and reuse of the alkali solution tank at the front end of the production line. The rear end is equipped with a bag filter 4. The self-cleaning filter 2 is used for primary filtration of the alkali solution in the alkali solution tank at the back end of the production line. The rear end is equipped with a bag filter 4, achieving purification and recovery through two-stage filtration. The oil removal tank 3 is used to separate saturated saponified substances in the alkali solution. The saponified substances produced by the saponification reaction are precipitated from the alkali solution and then scraped into the waste liquid vehicle for collection, thereby removing the oil content in the alkali solution. The bag filter 4 uses a bag filter system for fine filtration, typically with a filtration accuracy of 1.5-5 μm. Compressed air is used to blow solids from the filter bags to the oblique trough 5, removing fine particles that were not removed by the pre-filtration process. This allows for filtration and alkali recovery. The oblique trough 5, located at the bottom of the inclined tube sedimentation tank 1 and the bag filter 4, receives impurities such as iron powder and oil sludge that have been precipitated and filtered. The slag discharger 6 regularly removes impurities such as iron powder and oil sludge to a waste collection vehicle 7. The collection vehicle 7 collects impurities such as iron powder and oil sludge generated by the equipment. The liquid supply pump 8 delivers alkali from the alkali solution tank to be purified or the inclined tube sedimentation tank 1 to a designated tank according to process requirements. The alkali mist recovery system 9 recycles alkali mist during equipment operation to protect the environment. The piping system 10, integrated with the equipment and pumps, provides alkali supply and liquid recovery. The compressed air system 11 is used to activate valves and provide airflow to the bag filter 4, utilizing the factory's existing pipeline air. The steel structure platform 12 is used for equipment support and generally has two to three layers.

[0019] Furthermore, one end of the electronic control system 13 is connected to the production line power supply, and the other end is connected to the bag filter 4, the slag discharger 6, the collection vehicle 7, the liquid supply pump 8, the alkali mist recovery system 9, the pipeline system 10 and the compressed air system 11. The electronic control system 13 is used for the automatic control of the complete set of equipment.

[0020] Differently, each of the collecting vehicles 7 and the liquid supply pump 8 is provided in a group, and each of the collecting vehicles 7 and the liquid supply pump 8 in a group is symmetrically distributed. The collecting vehicle 7 is used to collect impurities such as iron powder and sludge generated by equipment filtration, and the liquid supply pump 8 transports the alkali liquid in the alkali liquid tank to be purified or the inclined tube sedimentation tank to the designated tank body according to process requirements.

[0021] Working Principle: During operation, the alkali liquor to be filtered is first supplied from the original alkali liquor tank by the 8 liquid supply pump to the 1 inclined tube sedimentation tank or the 2 self-cleaning filter for preliminary sedimentation and filtration. After filtration, some larger particles are deposited in the 5 inclined mouth tank. Through continuous sedimentation in the 5 inclined mouth tank, they are regularly automatically discharged to the 7 collection vehicle by the 6 slag discharger. After the completion of the preliminary filtration, the iron powder and residual oil are discharged and collected. The iron powder and residual oil that cannot be filtered out by the initial filtration are sent to the 4 bag filter or the 3 degreasing tank for secondary high-precision filtration or degreasing. The filtration accuracy can generally reach about 2μm. The fine particles remaining after the initial filtration are filtered again through high-precision filtration. The fine iron powder, residual oil and other impurities produced after filtration are deposited in the 5 inclined mouth tank, and then automatically discharged to the 7 collection vehicle by the 6 slag discharger according to the set time, completing the discharge and collection of the filtered materials. After the above two layers of filtration, the alkali liquid reaches a clear and clean state. The clean alkali liquid automatically overflows back to the original alkali liquid tank that needs to be purified through the overflow hole at the upper end of the equipment. The whole process is fully automatically controlled by the 13 electronic control system. In this way, the alkali liquid that needs to be purified is filtered and purified in real time to achieve the purpose of recycling and reuse.

The problem solved by the utility model is that the alkali solution of the existing production unit cannot be recovered. Alkali liquor can be recycled and reused, but it will pollute the environment and the cost of treating waste alkali liquor is high, which leads to the problem that alkali liquor treatment is very difficult. The utility model solves the problem that alkali liquor in production units cannot be recycled through the combination of the above components. The device is used 24 hours a day and keeps working online in real time. The working efficiency is extremely high. The processing capacity of each unit can reach 20 cubic meters per hour. It can be used in conjunction with the original alkali liquor equipment and can be installed near the original equipment and put into use.
