The invention discloses an underground water extraction and reinjection circular treatment device, and relates to the technical field of underground water treatment.The underground water extraction and reinjection circular treatment device comprises an equipment frame, a servo motor is fixedly installed above the equipment frame, and a transmission shaft is fixedly installed at the output end of the servo motor; a supporting plate is fixedly installed on the inner wall of the equipment frame, the end, away from the servo motor, of the transmission shaft rotationally penetrates through the upper wall and the lower wall of the supporting plate, a water outlet pipe fixedly penetrates through the surface of the equipment frame, and a water inlet pipe fixedly penetrates through the bottom of the equipment frame; the purification device comprises a separation frame, a fixing rod, a sleeve, a lifting frame, a purification frame, a filter plate and a fixing plate, the underground water extraction and reinjection circulation treatment device can effectively remove peculiar smell and colored pollution under the action of activated carbon, meanwhile, large-particle impurities are effectively removed, and the purification effect on underground water is improved.

The application discloses a kind of intelligent filter-pressing devices and processes suitable for organic silicon of filter-pressing device technical field, including support seat, the front and rear ends of the support seat are all fixedly connected with main beam, and the side away from support seat between two main beams is fixedly connected with thrust plate;After the end of filter-pressing, external controller will control drive block to open filter plate one by one, filter cake falls off, during the movement of filter plate, filter cloth will be separated from filter plate under the action of separation plate, which is conducive to the separation of filter cloth and filter plate, the filter residue attached to the surface of filter cloth can be separated from filter plate, which is convenient for subsequent cleaning, to avoid filter cloth and filter plate sticking together during cleaning, filter residue will be closely attached to the surface of filter cloth and filter plate during filter-pressing, which makes it difficult to clean;Subsequently, the filter residue on the surface of filter cloth will be scraped off by scraping block, which is conducive to cleaning the filter residue remaining on the surface of filter cloth after one filter-pressing, to avoid the influence of residual filter residue on the filtering effect of filter cloth.

The utility model provides a waste gas catalytic combustion treatment device which comprises a combustion box, a filter box used for high-temperature waste gas is arranged on one side of the combustion box, a plurality of filter screens are arranged in the filter box, a flow equalizing plate is arranged on one side of the filter screens, and an activated carbon filter layer is arranged on one side of the flow equalizing plate. One side of the combustion box is connected with an air inlet pipe, one side of the filter box is connected with an air outlet pipe, the top of the combustion box is connected with a breather pipe, the other end of the breather pipe extends into the filter box, and the top of the filter box is provided with a dismounting mechanism for replacing the filter screen. The waste gas catalytic combustion treatment device provided by the utility model solves the problems that a filter box of an existing device is integrally arranged, so that a filter screen and an activated carbon filter layer in the filter box are inconvenient to disassemble and replace, and the filtering effect of the filter box on high-temperature waste gas is reduced along with the prolonging of time; the waste gas treatment efficiency of the device is reduced.

The invention relates to the technical field of powder material filtering equipment, and discloses a copper chloride dry method standby filtering device which comprises a shell part, the bottom of an inner cavity of the shell part communicates with a negative pressure pump station, and the inner cavity of the shell part is movably sleeved with a filtering assembly for filtering copper chloride crystals. One end of the filtering assembly extends to one side of the exterior of the shell part, and a feeding part with one end extending to the other side of the exterior of the shell part is arranged in an inner cavity of the filtering assembly. According to the copper chloride dry-process standby filtering device and the filtering method thereof, the shell part and the filtering assembly are arranged, negative pressure can be formed in the inner cavity of the shell part and the periphery of the filtering bag, when a certain area of the filtering bag rotates and moves to the highest point, under the action of gravity, the part, in the area, of the filtering bag is bent towards the inner side, and therefore the filtering effect of the filtering bag is improved. And the impurities adsorbed on the inner wall of the material discharging plate are shaken off to the material discharging plate so as to be discharged out of the material discharging plate.

The invention discloses an oil and gas purification device with high purification efficiency, and the invention relates to the technical field of oil and gas purification. The oil and gas purification device with high purification efficiency can sequentially complete condensation separation and filtration separation of the transported oil and gas through the polymer filter membrane installed in the condenser and the filter cartridge, and can improve the filtering effect of the oil and gas secondary filtration through the setting of the polymer filter membrane, which is better than the traditional purification device, and at the same time ensures the operation efficiency of the equipment, and can automatically stretch under pressure when blocked through the setting of the polymer filter membrane, and complete the automatic cleaning operation of the polymer filter membrane through the operation of the cleaning rod and the cleaning scraper, effectively avoiding the polymer filter membrane from being affected by the filtering effect due to the adhesion of impurities when in use, and effectively improving the purification effect of the oil and gas.
