Atomization preparing apparatus and method for wax emulsion

Abstract

The invention discloses a device and a method for atomizing a wax emulsion. The device comprises the following parts: a discharge door on the reactor, a hot-water pipe, a host material pipe, a finding pipe with an atomized injector on the front end, wherein every atomized injector is extended in the reactor, the hot-water pipe, the host material pipe and the finding pipe are equipped with water pump, the host material pump and the finding pump separately. The method comprises the following steps: a, putting the hot water, the liquid wax and the findings in the water pipe, the host material pipe and the finding pipe; ejecting and forming the little drop from the atomized injector by increasing the pressure with the water pump, the host material pump and the finding pump; b, forming the big drop by attracting and gathering the little drop in the reactor; depositing to the bottom of the reactor; c, discharging the wax emulsion from the reactor. The wax emulsion which is prepared with the invention is provided with the good dispersity and homogeneity.

Description

technical field [0001] The invention belongs to the field of chemical product manufacturing, and in particular relates to a paraffin emulsion atomization preparation device and method. Background technique [0002] Paraffin wax emulsion is widely used in wood processing industry, paper industry, porcelain industry, agriculture, forestry and construction industry. Paraffin wax emulsion refers to paraffin wax evenly dispersed in water, with the help of directional adsorption of emulsifier, it is made under the action of mechanical external force A homogeneous fluid containing wax and water. Dispersion and stability are the main indicators for evaluating the properties of paraffin emulsions. Liquid paraffin and water are immiscible. It needs the directional adsorption of emulsifiers to make paraffin evenly dispersed under the action of external mechanical force. into water to form an emulsion, and the dispersibility and stability of the paraffin emulsion obtained by different p...

Problems solved by technology

[0003] The preparation method of the paraffin emulsion disclosed in the patent documents CN1388222 and CN1435468 is: chop the paraffin wax, put it in the reactor, heat it to melt the wax, then add it to hot water at 60 to 90 °C, and stir for 30 to 60 minutes. Add emulsifier and defoamer, after the stirring is completed, cool to obtain paraffin emulsion, but the defect in the preparation method of paraffin emulsion in the prior art is that the paraffin emulsion is prepared by stirring method, and the particles of paraffin emulsion are relatively large and dispersed. Poor uniformity and stability
