Description

Technical Field

[0001] The utility model relates to the technical field of butyl acetate recovery, in particular to a butyl acetate recovery and reuse device. Background Art

[0002] With the development of industry, organic solvents are used more and more widely. Solvents are mainly used in paints, coatings, printing, medicine, papermaking, textiles and chemicals. The organic matter volatilized during the use of solvents has great harm to the environment and human health. Butyl acetate, referred to as butyl acetate. A colorless, transparent liquid with a pleasant fruity odor. Lower homologues are difficult to dissolve in water; miscible with organic solvents such as alcohols, ethers, and ketones. Flammable. Acute toxicity is low, but it is highly irritating to the eyes and nose, and can cause anesthesia at high concentrations. Butyl acetate is an excellent organic solvent with good solubility for ethyl cellulose, cellulose acetate butyrate, polystyrene, methacrylate resin, chlorinated rubber and a variety of natural gums. In order to protect the environment and save resources, excess butyl acetate needs to be recycled and reused through a recycling device.

[0003] Patent No. CN202021959593.1 discloses a butyl acetate recovery and reuse system, including a support rod, a recovery barrel, a waste collection barrel and a body, wherein a distillation device is arranged inside the body, and the distillation device includes a controller, a switch, a display, an indicator light, a collection box, a discharge pipe, a swivel, a shaft, a machine cover, a temperature sensor, an electric wire, an alarm, a heater, a machine cavity, a butyl acetate solution, a discharge port, a waste solution and a reused solution; in the utility model, it is necessary to turn on the switch, at which time the display on the top of the machine body will be heated, and the butyl acetate to be recycled will be placed inside the machine cavity, and then the machine cover will be rotated with the shaft as the rotating point to seal it. The butyl acetate solution inside the machine cavity will gradually decompose into two types as the temperature rises, and then the effect of recycling and reusing butyl acetate can be achieved, thereby reducing resource waste and reducing production costs.

[0004] The above-mentioned butyl acetate recovery and reuse device realizes the decomposition and recovery of butyl acetate by distillation. When butyl acetate evaporates and decomposes, it will be vaporized, and it will be cooled and liquefied during the recovery process. During this conversion process, heat exchange will be continuously performed, thereby causing the temperature of the guide pipe and the recovery structure to continue to rise. After the temperature rises, the cooling effect of the gaseous butyl acetate will be reduced, thereby reducing the recovery efficiency of butyl acetate. In addition, since butyl acetate in the waste liquid material is recovered, and the waste liquid usually contains solid impurities, the impurities will absorb heat during the heating process, so more energy is consumed for heating, which increases the recovery cost. To this end, we propose a butyl acetate recovery and reuse device. Utility Model Content
