Degassing device used before high pressure hydrolysis of glycerol stearate

Abstract

The invention discloses a degassing device used before high pressure hydrolysis of glycerol stearate. The degassing device comprises a raw oil tank, a reactor, a cyclone separation tank and a degassed oil storage tank, wherein a heating jacket sleeves the raw oil tank, a water vapor inlet pipe is arranged at the top of the heating jacket, a drain pipe is arranged at the bottom of the heating jacket, the reactor is composed of a feeding pipe, a reaction pipe and a discharging pipe connected with one another in sequence, the inlet end of the feeding pipe is connected to a tee joint, one feeding hole of the tee joint is communicated with the raw oil tank via a hose pump, another feeding hole of the tee joint is connected to a water vapor generator, the reaction pipe is provided with a wavy pipe body, the discharging pipe of the reactor is communicated with the top of the cyclone separation tank, the bottom of the cyclone separation tank is communicated with the degassed oil storage tank, and the top of the cyclone separation tank is communicated with the heating jacket via a recovery pipe. The degassing device effectively enables water vapor and raw oil to be mixed uniformly so as to ensure a good degassing effect of the raw oil, can work continuously for a long period, and is low in running cost.

Description

technical field [0001] The invention belongs to the field of chemical production equipment, in particular to a degassing device before high-pressure hydrolysis of glyceryl stearate. Background technique [0002] The current chemical reaction equipment can be roughly divided into three categories: ①Reaction kettle (tank, tank); ②Reaction (absorption) tower; ③Reaction tube. ①, ② Not only the cost is high, but also the problem of uneven heating or heat release is not easy to discharge, which is also one of the main reasons for the amplification effect in chemical production; in addition, chemical reactions often need to be stirred, which faces the problem of shaft sealing. Especially for high-pressure, high-temperature reactions and reactions that require high-speed stirring, it is more difficult or even impossible to solve the shaft sealing problem. ③Although it can overcome the above-mentioned shortcomings of ① and ②, it does not have a good ability to mix the reactants, so ...

AI Technical Summary

Problems solved by technology

① and ② are not only expensive, but also have the problem of uneven heating or difficult discharge of exothermic heat, which is also one of the main reasons for the amplification effect in chemical production; in addition, chemical reactions often require stirring, which faces the problem of shaft sealing. Especially for high-pressure, high-temperature reactions and reactions that require high-speed stirring, it is more difficult or even impossible to solve the problem of shaft sealing.

③Although it can overcome the above shortcomings of ① and ②, it does not have a good ability to mix the reactants, so it needs to be equipped with a reactant stirring and mixing device

However, the raw material glyceryl stearate is vacuum degassed before hydrolysis, and the low boiling point substances in it will quickly pollute the vacuum pump oil and reduce the ultimate vacuum of the vacuum pump.

Replacing the vacuum pump oil not only increases the production cost, but also takes time and labor
