Problems solved by technology

Therefore, the exhaust port of the traditional neutralization reactor is often blocked by air bubbles. When the exhaust port is blocked, the usual treatment method is to stop or reduce the flow of acidic and alkaline solutions. Therefore, neutralization The presence of air bubbles in the reactor greatly affects its production efficiency

Abstract

The invention discloses a device and a method for improving efficiency of a neutralization reaction in naphthalene water reducer production. The device comprises a neutralization reaction kettle, wherein a defoaming device is arranged at the upper part of the neutralization reaction kettle and comprises defoaming nets, and at least two layers of the defoaming nets are arranged vertically; the defoaming nets are of a net structure formed by multiple triangles, every four triangle vertexes are opposite to constitute a square, and a defoaming needle is arranged in the central position of each square; the defoaming needles arranged on every two adjacent layers of defoaming nets are staggered, and needle heads of the defoaming needles are arranged downwards. The device and the method are applied to the neutralization reaction in the naphthalene water reducer production and can inhibit foam generation and control foam size, foam is limited below an exhaust port of the neutralization reactionkettle, neutralization reaction efficiency can be improved, then cycle of the neutralization reaction is shortened, and preparation cost of a naphthalene water reducer is reduced to a certain degree.

Description

technical field [0001] The invention relates to the technical field of water reducers, in particular to a production technology and equipment of a naphthalene-based water reducer. Background technique [0002] Water-reducing agent is an admixture with water-reducing effect in concrete, which can improve construction conditions without increasing the water consumption of one party; improve the flexural and compressive strength of concrete; enhance the performance of concrete such as frost resistance and impermeability; at the same time, it can significantly Improve the workability and fluidity of concrete, improve the durability of concrete; or under the condition that the fluidity of concrete is basically the same and does not affect the workability, reduce the unilateral water consumption of concrete, reduce the water-binder ratio, and save the amount of unilateral cementitious materials. Water reducing agent has become the fifth necessary component of modern concrete besid...
