Description

Reaction equipment of formaldehyde-free crease-resistant finishing agent Technical Field The utility model relates to the technical field of textile chemical preparation equipment, in particular to reaction equipment of formaldehyde-free crease-resistant finishing agent. Background At present, the preparation of the crease-resistant finishing agent for textiles mainly adopts a polycarboxylic acid formaldehyde-free finishing agent, the synthesis process of the crease-resistant finishing agent generally involves multi-step reactions such as esterification, condensation and the like, and the requirements on reaction temperature, pressure and impurity control are high. The traditional reaction equipment adopts a single-pipe-diameter reaction kettle or a series reaction pipe, and has the following problems: The reaction efficiency is low, the single pipe diameter can not adapt to the different requirements of different reaction stages on the material flow rate and the mixing degree, the reaction is insufficient, and the product yield is low. The impurity treatment is difficult, solid impurities generated in the reaction process are easy to adhere to the inner wall of a pipeline, and the traditional vibration deslagging mode is difficult to thoroughly remove the impurities due to uneven vibration transmission or energy loss, so that the purity of the product is influenced and the service life of equipment is prolonged. Uneven temperature control, namely, the problems of side reaction and the like caused by heating lag and overhigh local temperature in the conventional jacket heating or electric heating mode, and the requirement of the reaction temperature cannot be met accurately.

The beneficial effects of adopting the further scheme are as follows: The reaction tubes with different diameters are matched with the tapered reducer, so that reactants can undergo different reaction spaces and flow rate changes in the flowing process. In the initial stage, the large-diameter first reaction tube provides sufficient space for fully mixing reactants, and as the tube diameter is gradually reduced, the flow speed of the reactants is increased, the pressure is increased, intermolecular collision is more frequent, the reaction is promoted to be deepened gradually, the reaction efficiency and the reaction degree are effectively improved, and the synthesis quality of the formaldehyde-free crease-resistant finishing agent is ensured. Further, a containing cavity is formed in the collecting box, and a collecting opening is formed in the corresponding position of the first reducing pipe and the second reducing pipe in the containing cavity.
