Problems solved by technology

[0005] At present, the acid-base dosing pump of the common acid-base neutralization treatment device mostly uses a small diaphragm dosing pump to control the dosing amount. This control method has a small flow rate and the pump port is easy to block, resulting in poor acid-base neutralization effect. Well, there is no way to

Abstract

The invention discloses a fumaric acid synthesis reaction device, which comprises a regulation instrument (1), a dosing mixing instrument (2) and a reaction instrument (3). The regulation instrument (1), the dosing mixing instrument (2) and the reaction instrument (3) are connected in order through pipelines (4). One side of the regulation instrument (1) is provided with a water inlet (5), and one side of the reaction instrument (3) is provided with a water outlet (6). A sewage lifting pump (7) is disposed between the regulation instrument (1) and the dosing mixing instrument (2). The dosing mixing instrument (2) is internally provided with a pH sensor (8) and an automatic control instrument (9). The reaction instrument (3) is internally provided with a blender (10) and a pH analyzer (11) connected to the automatic control instrument (9). The acid-base neutralization device involved in the invention can accurately control the pH value, ensures the acid-base neutralization effect, and facilitates subsequent processes.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a fumaric acid synthesis reaction device. Background technique [0002] Neutralization treatment is one of the chemical treatment methods of wastewater. The basic principle is to make the anions and cations in acidic wastewater, or make the anions in alkaline wastewater interact with external cations to generate weakly dissociated water molecules, and at the same time generate other salts that are soluble or difficult to dissolve, thereby Eliminate their harmful effects. The method can treat and recycle acidic wastewater and alkaline wastewater, and can adjust the pH value of acidic and alkaline wastewater. [0003] Wastewater from factories is often acidic or alkaline. If it is discharged directly, it will cause water pollution, so a series of treatments are required. Alkaline sewage needs to be neutralized with acid, and acidic sewage needs to be neutralized with...
