Problems solved by technology

Practice has proved that the removal rate of impurities in silica gel by this method is low, which affects product quality, and the regeneration of silica gel consumes electric energy and produces waste silica gel at the same time, which violates the general trend of environmental protection and low carbon in industrial production.

Embodiment 1

[0024] The refining method of liquefied paraffin in this embodiment is divided into the following steps:

[0025] 1. Pass the 45°C liquid paraffin raw material into the liquid paraffin purifier from the oil inlet, and simultaneously pass 40°C hydrochloric acid into the liquid paraffin purifier from the acid inlet, and the liquid paraffin raw material and the hydrochloric acid are fully contacted through the mixing device;

[0026] 2. After the two liquids are fully contacted, the liquid paraffin floats upward naturally and is discharged from the oil outlet to obtain refined liquid paraffin; the water in the liquid paraffin raw material settles down with hydrochloric acid and is discharged from the acid outlet; at the same time, the solid in the mixed liquid Impurities naturally sink to the bottom and are regularly discharged from the slag outlet.

[0027] Such as figure 1 The liquefied paraffin purifier used in the liquid paraffin refining method of the present embodiment sh...

Embodiment 2

[0029] The refining method of liquefied paraffin in this embodiment is divided into the following steps:

[0030] 1. Pass the 50°C liquid paraffin raw material into the liquid paraffin purifier from the oil inlet, and simultaneously pass 45°C hydrochloric acid into the liquid paraffin purifier from the acid inlet, and the liquid paraffin raw material and the hydrochloric acid are fully contacted through the mixing device;

[0031] 2. After the two liquids are fully contacted, the liquid paraffin floats upward naturally and is discharged from the oil outlet to obtain refined liquid paraffin; the water in the liquid paraffin raw material settles down with hydrochloric acid and is discharged from the acid outlet; at the same time, the solid in the mixed liquid Impurities naturally sink to the bottom and are regularly discharged from the slag outlet.

Abstract

The invention discloses a method for refining liquid paraffin and belongs to an important link in the industrial production process of chlorinated paraffin. Compared with the traditional silicon gel adsorption and dehydration process, the method has the advantages that moisture and impurities in the liquid paraffin are purified by fully utilizing characteristic differences between by-product hydrochloric acid generated in the chlorinated paraffin production process and liquid paraffin raw materials, and silicon gel is not required to be bought additionally, so that energy is saved, the cost is reduced, and pollutants namely waste silicon gels are reduced. The invention also provides a device, namely a liquid paraffin purifier which is used in the method for refining liquid paraffin. The liquid paraffin purifier is rational in design, easy to mount, low in cost and convenient to operate, the production efficiency can be guaranteed, and the product quality is improved.

Description

technical field [0001] The invention relates to a refining method and device, in particular to a liquid paraffin refining method and device. Background technique [0002] Chlorinated paraffin is a chlorinated derivative of C10-C30 paraffin, commonly known as chlorinated alkanes, with low volatility, flame retardancy, good electrical insulation, chemical resistance, low price, good compatibility with PVC resin, etc. Advantages: It can be used as a flame retardant and PVC auxiliary plasticizer. It is widely used in plastics, cables, floor materials, hoses, artificial leather, rubber and other products. It is also used as an additive for paints and lubricating oils. Because of its wide processing temperature range, it is widely used, especially in metal processing. At present, there is no other product that can replace chlorinated paraffin. At the end of the 1950s, my country's chlorinated paraffin products began to be industrialized, and the market application has always been...
