The invention relates to the field of tetrachlorophthalic anhydride crystallization, in particular to a crystallization device for tetrachlorophthalic anhydride production, which comprises a machine body, the top end of the machine body is fixedly connected with a driving motor, the machine body is internally provided with a driving cleaning mechanism, and the driving cleaning mechanism is provided with a relative linkage mechanism. Through mechanical coupling of the unique driving cleaning mechanism and the multifunctional stirring mechanism, under driving of a single driving motor, powerful mixing of materials and continuous cleaning of a device wall are synchronously completed, a first scraper and a second scraper are attached to the inner wall in a self-adaptive mode under the action of centrifugal force, crystal deposition is effectively removed online, and the service life of the device is prolonged. The high-efficiency heat exchange state of a heat transfer surface is maintained, and cooling efficiency attenuation and process fluctuation caused by scaling are avoided, so that the necessary periodic shutdown kettle cleaning link in the traditional process is fundamentally reduced, the annual effective operation time of the device is greatly prolonged, the maintenance cost and the energy consumption are reduced, and stable, continuous and high-efficiency production is realized.

The utility model discloses a flushing device for solving ammonium sulfate crystal substances at a joint of an absorption tower and flue gas in a sulfur recovery process, which relates to the technical field of sulfur recovery and comprises an absorption tower component, the absorption tower component comprises a flue, a flushing component is arranged in the flue, one side of the flue is provided with a flue gas joint, and the other side of the flue is provided with a water inlet. The flushing assembly comprises a communicating ring, the communicating ring is fixedly installed in the middle of the inner side of the flue, the communicating ring communicates with a plurality of spraying branch pipes, a plurality of spray head connectors are formed in one sides of the spraying branch pipes, the spray head connectors are arranged at equal intervals, and the spray head connectors face the inner side wall of the flue; a spiral spray head is fixedly mounted in the spray head connector; according to the utility model, the flue blockage caused by crystal deposition can be effectively avoided, the flue can be cooled, the gas phase distribution in the flue is more uniform, the absorption effect of the absorption tower assembly is improved, and the practical value is higher.

The utility model relates to the technical field of medicine processing auxiliary equipment, in particular to a bezoar bed which comprises a shell and a cloth bag, a convex thorn group is arranged outside the shell, one end of the shell is provided with a circular opening, the other end of the shell is provided with a connecting port, and the bottom end of the cloth bag extends into the shell and is fixedly connected with the connecting port; when the bezoar bed needs to be implanted into the cow gall bladder, a deposition medium is added into the shell, the cloth bag is folded to wrap the outer side of the shell, the cloth bag is closed below the connecting port, and then the bezoar bed is implanted into the cow gall bladder; friction force between the calculus bovis and the gall bladder can be increased, a calculus bovis bed is prevented from flowing into the intestinal canal or blocking the bile duct through the bile duct, calculus bovis crystal precipitation is facilitated, the crystal attachment surface is improved, the calculus bovis crystal adsorption capacity is better, and the calculus bovis yield is improved.
