Description

Technical Field

[0001] This utility model relates to the field of activated carbon purification reactor technology, specifically a porous activated carbon reactor for purifying heavy metals. Background Technology

[0002] An activated carbon purification reactor is a device used to treat waste gas and wastewater. It mainly utilizes the high adsorption performance of activated carbon to remove pollutants. Activated carbon is a highly porous structure made of natural or artificial materials with a large specific surface area, which enables it to effectively adsorb various organic and inorganic pollutants, such as organic solvents, volatile organic compounds, chlorides, heavy metals, and odor substances.

[0003] With the acceleration of industrialization, the discharge of wastewater containing heavy metals is increasing, posing a serious threat to the environment and human health. In existing technologies, activated carbon purification reactors are usually used to filter heavy metals from industrial wastewater. However, in order to avoid the loss and damage of activated carbon, traditional activated carbon purification reactors usually contain activated carbon in an integrated mounting frame. After long-term use, it is not convenient to remove the activated carbon separately for regeneration. The activated carbon and the mounting frame can only be discarded together, leaving no room for reuse of activated carbon, thus causing waste. Utility Model Content

[0004] The purpose of this invention is to provide a porous activated carbon reactor for purifying heavy metals, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A porous activated carbon reactor for purifying heavy metals includes a tank with an inlet / outlet at the bottom, a detachable bottom cover installed at the bottom of the tank, and several vertically stacked trays inside the tank, each containing porous activated carbon. The tank has an inlet at the top and a drain outlet at the bottom of the bottom cover. The bottom cover is used to seal the inlet / outlet at the bottom of the tank. Each tray has a pouring opening at the top for pouring the porous activated carbon. When the carbon is loaded into the tank, the upper tray presses and seals the pouring opening of the adjacent lower tray. The bottom of the lowest tray abuts against the inner wall of the bottom cover.

[0007] Therefore, when assembled, the upper container presses and seals the pouring opening of the adjacent lower container, and the bottom of the lowest container is in contact with the inner wall of the bottom cover. After long-term use, the bottom cover can be removed from the bottom of the tank, and the container can be taken out of the tank. Separating the upper and lower adjacent containers will remove the seal on the pouring opening at the top of the container, making the overall assembly and disassembly quick and convenient. This allows the porous activated carbon inside the container to be taken out for regeneration, so that the porous activated carbon can be reused, effectively reducing operating costs.

[0008] Furthermore, the container is composed of an annular side wall, an interceptor plate, and partitions. The interceptor plate is fixed to the inner wall of the annular side wall near the bottom. Several holes for wastewater to flow are evenly distributed on the interceptor plate. Several partitions are fixed in an array around the axis of the annular side wall inside the annular side wall and located above the interceptor plate. A holding cavity is formed between two adjacent partitions. Porous activated carbon is filled into each holding cavity.

[0009] Furthermore, during loading into the tank, the upper interceptor plate presses against the top of the adjacent lower annular side panel to seal the pouring opening at the top of the lower annular side panel.

[0010] Furthermore, a press-fit cylinder is fixed to the inner top wall of the liquid inlet, and a pressure plate is fixed to the bottom end of the press-fit cylinder. The pressure plate has holes evenly distributed for wastewater to flow through. The pressure plate can be matched and pressed against the top of the uppermost annular side wall to seal the tipping opening at the top of the uppermost annular side wall.

[0011] Furthermore, the bottom cover is screwed onto the bottom of the tank via a threaded connection, and a rubber ring is fixed on the end face of the bottom cover. When the bottom cover is screwed into place, the rubber ring comes into contact with and fits against the inner wall of the tank.

[0012] Furthermore, at least two insert rods are fixed in an array around the inner end wall of the bottom cover, and both insert rods extend vertically upward. Each annular side wall is provided with a number of insertion holes corresponding to the insert rods in an array around its axis. When the whole assembly is completed, the insert rods are inserted into the corresponding insertion holes on each annular side wall.

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

[0014] 1. When assembled, the upper container presses and seals the tilting opening of the adjacent lower container, and the bottom of the lowest container abuts against the inner wall of the bottom cover. After long-term use, the bottom cover can be removed from the bottom of the tank, and the container can be taken out of the tank. The upper and lower adjacent containers can be separated, thus eliminating the need to seal the tilting opening at the top of the container. This makes the overall assembly and disassembly quick and convenient, and facilitates the removal of the porous activated carbon in the container for regeneration, allowing the porous activated carbon to be reused and effectively reducing operating costs.

[0015] 2. This utility model utilizes an annular side-enclosed interceptor plate to form a disc body, and arranges partitions in an array within the disc body to divide the annular side-enclosed area into multiple holding chambers. The porous activated carbon is placed in the holding chambers in sections, which can ensure that the porous activated carbon is evenly distributed within the annular side-enclosed area and effectively improve the purification effect on wastewater.

[0016] 3. This utility model uses the upper intercepting plate to press and seal the top of the lower annular side panel, and uses the pressure plate to seal the top of the uppermost annular side panel. This can effectively prevent leakage of porous activated carbon in each annular side panel. In addition, there is no need to set up additional parts to seal the pouring openings at the top of each annular side panel. While ensuring that the overall assembly and disassembly are convenient and quick enough, the overall structure is simple and the manufacturing cost is reduced.

[0017] 4. This utility model combines the bottom cover being located at the bottom of the tank, the pouring opening on the serving tray being located at the top of the annular side circumference, and the characteristic that the serving tray can be removed from the bottom of the bottom cover. When the serving tray is removed, the pouring opening on it is located at the top, thus preventing the porous activated carbon inside from leaking out at will. Attached Figure Description

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-5 This utility model provides a porous activated carbon reactor for purifying heavy metals, comprising a tank 1 with an inlet / outlet at the bottom, a detachable bottom cover 2 installed at the bottom of the tank 1, and several vertically stacked trays 3 arranged inside the tank 1, each containing porous activated carbon 4. The porous activated carbon 4 is an activated carbon with a high specific surface area and rich pore structure. This activated carbon material is prepared by existing processes and has excellent heavy metal adsorption performance. The multiple trays 3 are stacked and arranged inside the tank 1, making the porous activated carbon 4 a multi-layered layout, which can provide a multi-layered over-adsorption effect for heavy metals in wastewater.

[0028] The tank 1 has an inlet 11 at the top and a drain 21 at the bottom of the bottom cover 2. The bottom cover 2 is used to seal the opening at the bottom of the tank 1. Each container 3 has a pouring opening at the top for pouring out the porous activated carbon 4. When this porous activated carbon heavy metal purification reactor is in use, wastewater is introduced through the inlet 11. The wastewater flows through multiple layers of porous activated carbon 4, where the porous activated carbon 4 adsorbs the heavy metals in the wastewater. The purified water is then discharged through the drain 21 on the bottom cover 2.

[0029] In this porous activated carbon heavy metal purification reactor, the bottom cover 2 is detachably installed below the tank body 1. When it is installed in the tank body 1, the upper loading plate 3 presses and seals the pouring opening of the adjacent lower loading plate 3. The bottom of the lowest loading plate 3 is in contact with the inner wall of the bottom cover 2. After long-term use, the bottom cover 2 can be removed from the bottom of the tank body 1, and the loading plates 3 can be taken out of the tank body 1. Separating the upper and lower adjacent loading plates 3 can remove the sealing of the pouring opening at the top of the loading plate 3, making the overall disassembly and assembly quick and convenient. This facilitates the removal of the porous activated carbon 4 from the loading plate 3 for regeneration, allowing the porous activated carbon 4 to be reused and effectively reducing operating costs.

[0030] Specifically, the holding tray 3 consists of an annular sidewall 31, an interceptor plate 32, and partitions 33. The interceptor plate 32 is fixed to the inner wall of the annular sidewall 31 near the bottom. The interceptor plate 32 has several holes evenly distributed on it to allow wastewater to flow through. It can effectively intercept the porous activated carbon 4 from below the annular sidewall 31, preventing the porous activated carbon 4 from leaking out from below the annular sidewall 31. Several partitions 33 are fixed in an array around the axis of the annular sidewall 31 inside the annular sidewall 31 and above the interceptor plate 32. A holding cavity 34 is formed between two adjacent partitions 33. The porous activated carbon 4 is filled into each holding cavity 34. The annular sidewall 31 and the interceptor plate 32 form a tray, and the partitions 33 are arranged in an array inside the tray to divide the annular sidewall 31 into multiple holding cavities 34. The porous activated carbon 4 is placed in the holding cavities 34 in sections, which can ensure that the porous activated carbon 4 is evenly distributed in the annular sidewall 31 and effectively improve the purification effect on wastewater.

[0031] Specifically, when the contents are loaded into the tank 1, the upper interceptor plate 32 presses against the top of the adjacent lower annular side panel 31 to seal the tipping opening at the top of the lower annular side panel 31.

[0032] A press-fit cylinder 12 is fixed to the inner top wall of the liquid inlet 11. A pressure plate 13 is fixed to the bottom end of the press-fit cylinder 12. The pressure plate 13 has holes evenly distributed on it for wastewater to flow through. The pressure plate 13 can be matched and pressed against the top of the uppermost annular side circumference 31 to seal the tipping opening at the top of the uppermost annular side circumference 31 and prevent the porous activated carbon 4 inside the uppermost annular side circumference 31 from leaking from above.

[0033] By using the upper interceptor plate 32 to press and seal the top of the lower annular side circumference 31, and using the pressure plate 13 to seal the top of the uppermost annular side circumference 31, leakage of porous activated carbon 4 inside each annular side circumference 31 can be effectively prevented. In addition, there is no need to set up additional parts to seal the pouring openings at the top of each annular side circumference 31. While ensuring that the overall assembly and disassembly are convenient and quick enough, the overall structure is simple and the manufacturing cost is reduced.

[0034] Specifically, the bottom cover 2 is screwed onto the bottom of the tank body 1 by thread matching, so as to achieve the effect of detachable bottom cover 2. A rubber ring 23 is fixed on the end face of the bottom cover 2. When the bottom cover 2 is screwed into place, the rubber ring 23 abuts and fits against the inner wall of the tank body 1. The rubber ring 23 plays an effective sealing role when the bottom cover 2 is screwed into place, preventing wastewater from leaking from the assembly gap between the bottom cover 2 and the tank body 1.

[0035] Furthermore, considering that the bottom cover 2 is located at the bottom of the tank body 1, the pouring opening on the container 3 is located at the top of the annular side circumference 31, and the container 3 is removed from the bottom of the bottom cover 2, when the container 3 is removed, the pouring opening on it is located at the top, thus preventing the porous activated carbon 4 inside from leaking out randomly.

[0036] Specifically, at least two insert rods 22 are fixed in an array around the inner end wall of the bottom cover 2, and both insert rods 22 extend vertically upward. Each annular side circumference 31 is provided with a number of insertion holes 311 corresponding to the insert rods 22 in an array around its axis. When the whole assembly is completed, the insert rods 22 are inserted into the corresponding insertion holes 311 on each annular side circumference 31. During assembly, by inserting the insert rods 22 into the insertion holes 311 on each annular side circumference 31, the installation of each holding tray 3 can be positioned. At the same time, during disassembly, it is prevented that the holding tray 3 will tilt to the side and cause leakage of porous activated carbon 4, thus ensuring stability during disassembly and assembly.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
