Embodiment Construction

[0023] Such as figure 1 , 2 Shown, a kind of weight-removing kettle recovery system for camphor production of the present invention mainly comprises: weight-removing kettle 100, naphtha receiving device 200, crystallization box 300, surplus oil tank 400, negative pressure vacuum device 500 and steam device 600. The deheavy still 100 is used to deheavily distill the residual oil and output it to the naphtha receiving device 200 , and recover the heavy oil after the deheavy distillation is connected to the bottom of the residual oil tank 400 . The lower end of the naphtha receiving device 200 is connected to the crystallization tank 300, the naphtha receiving device 200 is used for temperature-controlled storage of the distillate from the weight removal kettle 100, and the crystallization tank 300 is used to process the distillate stored in the naphtha receiving device 200 Crystallization to obtain camphor. During the whole recovery process, the negative pressure vacuum devic...

Abstract

The invention provides a de-heavy kettle recycling system and method for camphor production. The de-heavy kettle recycling system comprises a de-heavy kettle, the de-heavy kettle is used for conducting de-heavy and distilling on excessive oil and outputting the excessive oil to a camphor oil receiving device, and the lower end of the camphor oil receiving device is connected with a crystallizationbox; the de-heavy kettle recycling system is further provided with a negative pressure vacuum device to provide negative pressure for the de-heavy kettle and the camphor oil receiving device separately. According to the method, the de-heavy kettle is utilized to recycle camphor in the excessive oil. By means of the de-heavy kettle recycling system, the problem in the prior art that a lot of camphor in the excessive oil fails to be fully recycled is solved, the recycling rate of the camphor is increased, and the consumption of production raw materials is reduced.

Description

technical field [0001] The invention relates to a recovery system for camphor in residual oil, in particular to a recovery system for a weight-removing kettle for camphor production. [0002] The invention also relates to a method for recovering camphor from residual oil in the camphor production process. Background technique [0003] Camphor (synthetic) is a white crystal at room temperature. Camphor is pungent, hot and poisonous. GUIXIN, Spleen Channel. Efficacy Dehumidification and killing insects, warming and dispersing to relieve pain, resuscitating and eliminating foulness. Cure mainly scabies pruritus, bruises, toothache. Camphor has the effects of clearing the orifice, sharpening stagnation of qi, warding off filth, killing insects and relieving itching, reducing swelling and relieving pain, and is mainly used to treat symptoms such as scabies, pruritus, bruises, and toothache. It is mainly used for external medicine and resuscitating medicine. [0004] In the ...
