Description
Technical field
The utility model is applied to chlorinated paraffin preparation field, is related to a kind of liquid chlorine vaporization constant temperature and pressure control device.
Background technology
Chlorine extensive application in Chemical Manufacture, such as produce chlorinated paraffin.For safety and easy to use, chlorine exists
Using storing in liquid form as previous, referred to as liquid chlorine, and using when need to discharge in a gaseous form, therefore the use of chlorine needs
Undergo vaporescence.Liquid chlorine vaporization is a unstable process, often result in vaporization after chlorine gas pressure and temperature it is unstable, and
The fluctuation of pressure and temperature make it that metering is inaccurate, and the distribution of chlorine during the course of the reaction also becomes uneven, is unfavorable for whole
The stability contorting of production process.To solve this problem, it is necessary to develop a kind of stable perseverance of pressure and temperature after holding liquid chlorine vaporization
Warm constant-pressure control device.
But chlorine gas pressure, temperature and the instability of flow vaporized under prior art, have a strong impact on the follow-up life of chlorinated paraffin
Production.
Utility model content
In order to solve the technical problem of pressure, temperature and instability of flow after above-mentioned liquid chlorine vaporization, the utility model is intended to
A kind of new liquid chlorine vaporization constant temperature and pressure control device is provided.
To achieve these goals, technical scheme is as follows used by the utility model：
A kind of liquid chlorine vaporization constant temperature and pressure control device, including the liquid chlorine vaporization device on liquid chlorine woven hose, institute
The liquid chlorine entrance for stating liquid chlorine vaporization device is equipped with liquid chlorine regulating valve, output end and the chlorine appendix of the liquid chlorine vaporization device
It is connected, electric-heating belt is wrapped up on the chlorine appendix, the electric-heating belt is connected with temperature controller, controls its heating temperature
Degree, is provided with pressure sensing controller and temperature sensor on the chlorine appendix, the pressure sensing controller with it is described
The association control of liquid chlorine regulating valve, the temperature sensor associate control with the temperature controller.
Further preferred scheme is to be also equipped with flowmeter on the chlorine appendix.
Operation principle of the present utility model is：Pressure sensing controller is provided with chlorine appendix after liquid chlorine vaporization
And temperature sensor, pressure sensing controller and liquid chlorine regulating valve are associated control.Pressure sensing controller sets constant pressure
Force value, by controlling the opening degree of liquid chlorine regulating valve to adjust liquid chlorine flow when the chlorine gas pressure after vaporization fluctuates, and then make vaporization
Chlorine gas pressure afterwards is maintained at pressure value set in advance；Temperature sensor associates control, chlorine appendix with temperature controller
Temperature change, temperature sensor sends signal, by temperature controller control electric-heating belt heating to adjust chlorine temperature.
The stable chlorine of pressure and temperature can pass through flowmeter Accurate Determining after vaporization.
The utility model has the advantages that compared with the prior art：Solves the pressure and temperature after chlorine vaporization not
The problem of stable, it is more uniformly distributed the more stable reaction of chlorinated paraffin production that chlorine is participated in, chlorine gas metering is more accurate.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Wherein, 1. liquid chlorine vaporization device；2. liquid chlorine woven hose；3. liquid chlorine regulating valve；4. electric-heating belt；5. chlorine gas transmission
Pipe；6. flowmeter；7. pressure sensing controller；8. temperature sensor；9. temperature controller.
Embodiment
The technical solution of the utility model is further detailed below in conjunction with specific embodiment, but this practicality is new
The protection domain of type is not limited to that those skilled in the art are worked with non-creativeness changes its structure, should belong to this
The protection domain of utility model.
When producing chlorinated paraffin, liquid chlorine is entered and vapour is carried out in liquid chlorine vaporization device 1 chlorine by woven hose 2 first
Change, the pressure of the chlorine after vaporization is determined by pressure sensing controller 7, and temperature is determined by temperature sensor 8.
When the pressure value that pressure sensing controller 7 is determined and the pressure value pre-set are not inconsistent then by pressure sensing control
Device 7 processed controls the folding of liquid chlorine regulating valve 3 to control liquid chlorine to enter the flow of liquid chlorine vaporization device 1 so as to control chlorine after vaporization
Pressure.
Then transmitted when the temperature that temperature sensor 8 is determined is not inconsistent with predetermined temperature value to temperature controller 9
Signal, the heating-up temperature of electric-heating belt 4 is controlled by temperature controller 9 to make chlorine temperature constant.
The flow of chlorine can be by chlorine appendix 5 Accurate Determining of flowmeter 6.
