Abstract

The invention discloses a pre-reactor. The pre-reactor comprises a pre-reaction kettle, wherein the upper part of the pre-reaction kettle is connected with an alkaline liquid tank through a pipeline; an outlet is formed in the bottom of the pre-reaction kettle; two openings in the upper part of the pre-reaction kettle are connected with a vacuum compensator in parallel through pipelines; one end of the vacuum compensator is connected with a butterfly valve and a pressure sensor; the two ends of the vacuum compensator are connected with a control valve and a pressure sensor in parallel respectively; the vacuum compensator is a vacuum compensator made of a flexible material. Compared with the prior art, the problem that an aeration adjusting function of an existing pre-reactor cannot easily meet process requirements can be solved.

Description

Pre-reactor

Technical field

The present invention relates to chemical industry equipment manufacturing technology field, especially a kind of equipment for the pre-reaction of rosin based product.

Background technology

At present, in the process of manufacture of rosin based product, especially oxidizing process, needs to carry out pre-reaction, is exactly that pre-exposure regulates, and this is certainly to need aeration, large as much as possible in actual motion.If hydrolysis acidification, will see that front end water inlet situation considers whether to need aeration, even if need, can be not large yet, aeration rate is large can not meet anaerobic environment.And the existing pre-reactor for this pre-reaction, generally only include pre-reactor, pre-reactor top is connected with alkali liquid tank by pipeline, pre-reactor bottom is provided with outlet, with coupled reaction still, the top of pre-reactor is provided with the pressure limiting valve and the Pressure gauge that are connected to pre-reactor inner space, and to carry out aerating regulation, such only rely on pressure limiting valve and Pressure gauge cannot meet the process requirements of aerating regulation far away.Have afterwards at two openings on pre-reactor top and be parallel with a vacuum compensator by pipeline, but its aeration rate is when larger, easily really under bad border of vacuum, is producing negative pressure, the more difficult backflow of liquid, reduce reaction efficiency.

Summary of the invention

Problem to be solved by this invention is to provide a kind of pre-reactor, easily produces the problem of negative pressure to solve pre existing reactor aeration rate when large.

In order to address the above problem, technical scheme of the present invention is: this pre-reactor includes pre-reactor, described pre-reactor top is connected with alkali liquid tank by pipeline, described pre-reactor bottom is provided with outlet, two openings on the top of described pre-reactor are parallel with a vacuum compensator by pipeline, one end of described vacuum compensator is connected with butterfly valve and pressure sensor, the two ends of described vacuum compensator are parallel with control valve and pressure sensor, and described vacuum compensator is the vacuum compensator that flexible material is made.

In technique scheme, more specifically technical scheme can be: described flexible material is polytetrafluoroethylene (PTFE).

Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:

This pre-reactor is by being parallel with control valve and pressure sensor at the two ends of vacuum compensator, adopting vacuum compensator is that flexible material is made, the use of the retraction of flexible material and control valve and pressure sensor, solve in the pre-reaction that aeration rate is large, in equipment, easily produce the problem of larger negative pressure, and greatly strengthened the effect of vacuum compensator compensation buffering.This pre-reactor is to needing the oxidation reaction that aeration rate is larger to have good adaptability.

Brief description of the drawings

Fig. 1 is the front view of the embodiment of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:

Pre-reactor as shown in Figure 1, it includes pre-reactor 1, and pre-reactor 1 top is connected with alkali liquid tank 2 by pipeline, and the port of export of alkali liquid tank 2 is connected with butterfly valve and pressure sensor 4.Pre-reactor 1 bottom is provided with outlet 7, and this outlet 7 is with coupled reaction still.Two openings on the top of pre-reactor 1 are parallel with a vacuum compensator 5 by pipeline 3, one end of vacuum compensator 5 is connected with butterfly valve and pressure sensor 4, the two ends of vacuum compensator 5 are parallel with control valve and pressure sensor 6, the control valve here and pressure sensor 6 are connected on the pipeline and parallel pipeline 8 of the other end of vacuum compensator 5, and control valve can be selected the control valve of threeway.The vacuum compensator 5 that this vacuum compensator 5 is made for flexible material, here be the resistant to elevated temperatures polytetrafluoroethylene (PTFE) vacuum compensator 5 of high tenacity, the use of the retraction of flexible material and control valve and pressure sensor 6, solve in the pre-reaction that aeration rate is large, in equipment, easily produce the problem of larger negative pressure, and greatly strengthened the effect of vacuum compensator compensation buffering.
