Miscellaneous effect is good.
In order to achieve the above object, the present invention is achieved by the following technical solutions：
The present invention is a kind of method of purification of chlorinated paraffin raw material wax oil, and the method for purification comprises the following steps：
（1）Raw material wax oil passes through magnetic filter for tube under certain flow velocity（1）；
（2）By step（1）Middle process magnetic filter（1）Wax oil be passed through the washer containing chlorine, chlorine hydride mixed gas body
（2）Middle removal aromatic hydrocarbons and basic nitrogen；
（3）By step（2）In product be passed through quantizer（3）Middle stratification goes the removal of impurity, obtains pure wax oil.
Further improvement of the present invention is：The step（1）The flow velocity of middle wax oil is 1300-1500L/h.
Further improvement of the present invention is：In the step（2）Described in chlorine, hydrogen chloride gas be passed through gas flow
For 1500m3The ratio of chlorine and hydrogen chloride is volume ratio 0.5 in/h, gaseous mixture：100-3:100, the weight with wax oil intake
Than 1.2:1-1.3:1, time of washing be how long the 3-5min times, control temperature is at 60-90 DEG C.
Further improvement of the present invention is：In the step（3）In, the time of stratification is 3-4h.
A kind of purifying plant of chlorinated paraffin raw material wax oil, the device includes magnetic filter, the side of magnetic filter
Washer is connected with, the upper end of washer is provided with gas vent, quantizer is connected by pipeline in the lower end of washer, point
Exquisite wax oil outlet and hydrochloric acid gateway are additionally provided with layer device.
The beneficial effects of the invention are as follows：Raw material wax oil passes through magnetic filter for tube under certain flow velocity, due to magnetic
Suction-operated, remove tiny iron filings class impurity；Afterwards by containing chlorine, the washing of chlorine hydride mixed gas body, removing oxidizable
Aromatic hydrocarbons and basic nitrogen, stratification remove impurity, obtain pure wax oil.
The present invention realizes the method that the raw material wax oil of chlorinated paraffin removes impurity, and control is stable, impurity removal effect is good,
Chlorinated paraffin product quality is significantly improved.
Brief description of the drawings
Fig. 1 is the structural representation of purifying plant of the present invention.
Embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and further retouched in detail
