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

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...
