Abstract
The present invention is a kind of method of continuous removing chlorine in chlorinated paraffin hydrogen and chlorine residue, and methods described comprises the following steps：（1）Chlorinated paraffin is passed through to falling liquid film device at a certain temperature, steam is passed through in the upper end of falling liquid film device, hot blast is passed through in the lower end of the falling liquid film device.Thick chlorinated paraffin in the chlorinated paraffin production process of the present invention is at a certain temperature, by falling liquid film device, the chlorinated paraffin of downward gravity flowing is contacted with the dry air flowed up, at a certain temperature, the hydrogen chloride gas that liquid film is parsed is carried away by air in time, obtains pure chlorinated paraffin.The present invention realizes continuous removing chlorine in chlorinated paraffin hydrogen and chlorine residue, and step is simple, yield is big, less energy consumption, and hydrogen chloride and chlorine residue removing are clean, and product quality is high.
Description
Technical field
The invention belongs to chlorinated paraffin processing technique field, a kind of continuous removing chlorine in chlorinated paraffin is particularly related to
Change the method for hydrogen and chlorine residue.
Background technology
Now domestic and international chlorinated paraffin is accomplished continuously or intermittently method production, and the hydrogen chloride gas of generation and unreacted chlorine are molten
Solution is in chlorinated paraffin, and the later stage needs to be removed, and the method for existing chlorinated paraffin removing hydrogen chloride and chlorine residue takes drying
Air bubbling displacement method, vacuum aspiration；But both approaches all presence parsing areas are small, non-uniform temperature causes energy consumption
Greatly, unstable product quality, residual chloride hydrogen and chlorine residue are more, and are intermittently operated.
The content of the invention
In order to solve the above problems, the invention provides a kind of continuous removing chlorine in chlorinated paraffin hydrogen and the side of chlorine residue
Method, this method less energy consumption, can continuously be produced, and hydrogen chloride and chlorine residue removing are clean, and product quality is high.
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 continuous removing chlorine in chlorinated paraffin hydrogen and chlorine residue, and methods described comprises the following steps：
（1）Chlorinated paraffin is passed through to falling liquid film device at a certain temperature, steam is passed through in the upper end of falling liquid film device, in the falling liquid film device
Lower end is passed through hot blast；
Wherein：In the step（1）In, chlorinated paraffin is passed into falling liquid film device at 90-105 DEG C（1）In；
The flow velocity of chlorinated paraffin is 2.3-2.6t/h；
The temperature of steam is 115-135 DEG C；
The temperature of hot blast is 105-120 DEG C.
A kind of continuous removing chlorine in chlorinated paraffin hydrogen and the device of chlorine residue, device includes falling liquid film device, the one of falling liquid film device
Side upper end is provided with chlorinated paraffin import, steam inlet, and lower end is provided with hot wind inlet, condensation-water drain, in the upper of falling liquid film device
End is provided with hydrochloric acid outlet, and pure chlorinated paraffin outlet is provided with the lower end of falling liquid film device.
The beneficial effects of the invention are as follows：Thick chlorinated paraffin in the chlorinated paraffin production process of the present invention is in certain temperature
Under, by falling liquid film device, the chlorinated paraffin of downward gravity flowing is contacted with the dry air flowed up, at a certain temperature,
The hydrogen chloride gas that liquid film is parsed is carried away by air in time, obtains pure chlorinated paraffin.
The present invention realizes continuous removing chlorine in chlorinated paraffin hydrogen and chlorine residue, and step is simple, yield is big, less energy consumption, chlorine
Change hydrogen and chlorine residue removing is clean, product quality is high.
