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 [0001] The invention relates to the technical field of chemical equipment manufacturing, in particular to equipment for pre-reaction of rosin products. Background technique [0002] At present, in the production and processing of rosin products, especially the oxidation method, pre-reaction is required, that is, pre-aeration adjustment, which definitely requires aeration, and the actual operation should be as large as possible. If it is hydrolytic acidification, it depends on the water inlet conditions at the front end to consider whether aeration is required. Even if it is necessary, it will not be large, and a large aeration amount cannot meet the anoxic environment. And the existing prereactor that is used for this prereaction generally only comprises prereactor, and prereactor top is connected with lye tank by pipeline, and the bottom of prereactor is provided with outlet, to connect reactor, prereactor The upper part of the reactor is equipped with a pr...
