Problems solved by technology
[0002] At present, pharmaceutical factories produce a large amount of waste methanol or waste fusel alcohol in the pharmaceutical process. There is a certain amount of ammonia water, dichloropropane, and dichloromethane in the waste methanol or fusel alcohol. Among them, ammonia water will emit a pungent smell, and dichloropropane And methylene chloride will produce toxic and harmful gases during the combustion process, which will corrode the burner pipeline and cannot be used directly as fuel. At present, there is no way to solve this problem in China, so it has to be dumped as waste products, which is a waste of resources and harmful to the environment. environmental pollution

Embodiment Construction
[0024] Such as figure 1 As shown, the waste alcohol purification method includes an ammonia volatilization link and an ammonia recovery link, and is characterized in that the ammonia volatilization link includes the following specific steps:
[0025] 1. Spray the waste alcohol, inject the waste alcohol into the porous waste alcohol shower plate 3, so that the waste alcohol liquid falls in a linear shape;
[0026] 2. Air blowing, aiming at the waste alcohol liquid sprayed into a line and blowing into the air to take away the volatilized ammonia gas;
[0027] 3. Waste alcohol circulation, the waste alcohol liquid that has been sprayed is lifted to the waste alcohol shower plate 3 again, and steps 1 to 2 are repeated;
[0028] 4. Recover the ammonia-free alcohol liquid. After several cycles of waste alcohol showering, all the ammonia contained in it will be volatilized and become ammonia-free alcohol liquid. The purified alcohol liquid will be injected into the storage device ;...

The invention provides a method and a device for purifying waste alcohol, belongs to the technical field of recycling of alcohol-based fuel waste, and aims at mainly solving the problem in the prior art that waste alcohol is discarded as waste, resulting in resource waste and pollution to environment. The method for purifying the waste alcohol comprises an ammonia gas volatilization link and an ammonia gas recovery link, wherein the ammonia gas volatilization link comprises waste alcohol spraying, blowing, waste alcohol circulating, and recovery of alcohol fluid free of ammonia; the ammonia gas recovery link comprises clear water spraying, blowing in of air containing the ammonia gas, ammonium hydroxide circulating, and ammonium hydroxide recovery. The device for purifying the waste alcohol comprises a device shell, and is characterized by also comprising a waste alcohol circulating system, an ammonium hydroxide circulating system and a blowing system, wherein the waste alcohol circulating system is composed of a waste alcohol pump, a pipeline, a porous waste alcohol spraying plate and a waste alcohol purifying bin; the ammonium hydroxide circulating system is composed of an ammonium hydroxide pump, a pipeline, a porous ammonium hydroxide spray pump and an ammonium hydroxide bin; the blowing system is composed of a draught fan, an air inlet end, the device shell and an air outlet end; and the waste alcohol purifying bin and the ammonium hydroxide bin share the top and the bottom of the device shell, and are isolated with one another through a baffle plate.
Description
technical field [0001] The invention belongs to the technical field of waste alcohol-based fuel recovery and utilization, and in particular relates to a waste alcohol purification method and a device thereof. Background technique [0002] At present, pharmaceutical factories produce a large amount of waste methanol or waste fusel alcohol in the pharmaceutical process. There is a certain amount of ammonia water, dichloropropane, and dichloromethane in the waste methanol or fusel alcohol. Among them, ammonia water will emit a pungent smell, and dichloropropane And methylene chloride will produce toxic and harmful gases during the combustion process, which will corrode the burner pipeline and cannot be used directly as fuel. At present, there is no way to solve this problem in China, so it has to be dumped as waste products, which is a waste of resources and harmful to the environment. The environment is polluted.
