A kind of production equipment of carboxylic acid water reducing agent and production method thereof

Abstract

The invention provides production equipment and method for carboxylic acid water reducing agents. The production equipment comprises a reaction kettle, a burdening tank, a softened water storage tank, a mother solution storage tank, an acrylic acid storage device, a catalyst storage device, an acrylic acid dripping tank, a catalyst dripping tank, a powder delivery port, a pump, valves and sensors. The acrylic acid storage device, the burdening tank, the acrylic acid dripping tank, the reaction kettle, a catalyst input device and the catalyst storage tank are connected through pipelines with automatic valves. An acrylic acid input passage and a catalyst input passage work independently through switching on and switching off of the corresponding automatic valves. The powder delivery port is located in the pipeline communicated with the lower end of the reaction kettle and is controlled by the reaction kettle output automatic valve. In addition, the reaction kettle is connected with the mother solution tank through a pipeline with an automatic valve. The equipment can be quickly installed in a modularization mode, is safe and easy to operate, runs efficiently and is capable of automatically controlling a reaction process and adding of raw materials.

Description

technical field [0001] The invention belongs to the technical field of chemical preparation, and in particular relates to a production equipment of a carboxylic acid water reducer. Background technique [0002] Carboxylic acid water reducer, that is, the preparation process of polycarboxylate water reducer is difficult to control. The measurement of raw materials, the timing and speed of addition, and the temperature during the addition process will not only affect the performance of the obtained water reducer, but even affect the quality of the water reducer. It directly affects the progress of the polymerization reaction. If it is not properly controlled, detonation may occur, resulting in damage to the reactor. In more serious cases, it will lead to fire, causing huge losses to personnel's life safety and property. For a long time, the research and improvement of suitable carboxylic acid water reducer production equipment is a direction of efforts in this field. Content...
