This utility model discloses a comprehensive treatment system for zinc-containing waste generated in viscose fiber production, belonging to the field of waste treatment in viscose fiber production. The system includes a reaction tank, filter press, pretreatment device, filter, ion exchange resin column, and acid bath preparation tank, ensuring a comprehensive treatment pathway for zinc-containing waste. This facilitates the mixing of highly acidic, high-salt zinc-containing wastewater with zinc-containing sludge. The strong acidity of the wastewater allows for the acid leaching of zinc sulfide and zinc hydroxide in the sludge, simultaneously obtaining a zinc sulfate solution and recovering sulfate to prepare sodium sulfate and sulfuric acid. This reduces the salinity of the wastewater, thereby decreasing the amount of reagents used in treating zinc-containing wastewater, mitigating scaling risks, and reducing the load on subsequent biochemical systems.

The present application belongs to the technical field of instant meat product processing, and discloses an instant ham and a preparation method. The method comprises low-salt pickling and semi-mature fermentation, high-temperature three-gradient fermentation after slicing and addition of probiotics, and the combination of vacuum temperature-changing fermentation ripening and bacteriostatic process, and processes the instant ham which is quickly fermented and matured, reduces the content of salt, inhibits the growth of rancidity and harmful bacteria, and is convenient to eat after opening the bag. The present application first proposes that the meat product after rapid fermentation is vacuum packaged and then subjected to special vacuum high-temperature fermentation ripening and bacteriostatic treatment at a high temperature of 49-52 DEG C. The process can not only significantly shorten the fermentation time to about 110-120 minutes, but also basically kill the non-sporulated vegetative microorganism cells in the vacuum-packaged ham, while allowing the probiotics to be retained to a certain extent and avoiding the pollution of microorganisms and other harmful substances thereafter. The "fast, low-salt, flavor, instant" ham product prepared by the present application technology cannot be realized by the existing ham fermentation technology.

This invention belongs to the field of ketoxime synthesis technology and provides a method for synthesizing 3-pentanone oxime. The method uses 3-pentanone, hydrogen peroxide, and ammonia as raw materials, adds a catalyst, and reacts in a closed system. After the reaction, the mixture is filtered and distilled under reduced pressure to obtain 3-pentanone oxime. The catalyst is a fluorine-modified Ti-MOR molecular sieve, obtained by reacting the Ti-MOR molecular sieve with an NH4F-alcohol solution. The method provided by this invention features high yield, high purity, and low waste, with a single-pass yield ≥96% and purity ≥99.0%. The catalyst can be recycled up to 6 times without significant activity decline. The entire process involves no organic solvent discharge and low salt content in the wastewater, meeting the requirements of green production.

This utility model provides a wind turbine tower cooling device, aiming to solve the problem that existing offshore wind turbine tower cooling devices lack dehumidification and desalination filtration of sea air. It includes a filter pipe, a multi-stage filtration system, a cooling fan, a support frame, and a water storage pipe. The filter pipe contains the multi-stage filtration system and is fixedly mounted on the support frame. A cooling fan is installed on the air outlet pipe at the top of the filter pipe. The water storage pipe is connected to the bottom of the filter pipe through multiple drain pipes, and an electric heating wire is wound around the outside of the water storage pipe. The multi-stage filtration system includes a metal filter, filter cotton, and a cyclone filter. The metal filter, filter cotton, and cyclone filter are arranged sequentially. The positions of the air outlet pipe and the cyclone filter correspond to each other. This device can effectively dehumidify and desalinate sea air, preventing water vapor and salt from adversely affecting the equipment during heat dissipation.
