Abstract
The invention discloses a pre-reactor. The pre-reactor comprises a pre-reacting kettle, wherein the upper part of the pre-reacting kettle is connected with an alkaline solution tank through a pipeline, an outlet is formed in the bottom of the pre-reacting kettle, two openings at the upper part of the pre-reacting kettle are connected with a vacuum compensator in parallel through the pipeline, one end of the vacuum compensator is connected with a butterfly valve and a pressure sensor, and the two ends of the vacuum compensator are connected with a control valve and the pressure sensor in parallel. Compared with the prior art, the pre-reactor has the advantage that the problem that the aeration regulating function of the existing pre-reactor is difficult to meet technical requirements can be solved.
Description
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 pressure limiting valve and the Pressure gauge that is 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.
Summary of the invention
Problem to be solved by this invention is to provide a kind of pre-reactor, to solve the more difficult problem that meets technological requirement of pre existing reactor aerating regulation function.
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, and the two ends of described vacuum compensator are parallel with control valve and pressure sensor.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
This pre-reactor is parallel with a vacuum compensator by two openings of two place's opening parts at an upper portion thereof by pipeline, be parallel with control valve and pressure sensor with the two ends of vacuum compensator, can make aeration under vacuum state, complete completely, reach the technological requirement of pre-reaction, and can finely must regulate aeration rate, especially the in the situation that of larger aeration rate.This pre-reactor is to needing the oxidation reaction that aeration rate is larger to have good adaptability.
Accompanying drawing explanation
Fig. 1 is the front view of the embodiment of the present invention.
The specific embodiment
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.Can make like this aeration under vacuum state, complete completely, reach the technological requirement of pre-reaction, and can finely must regulate aeration rate, especially the in the situation that of larger aeration rate.
