Abstract
The utility model discloses an automatic cutting device for supplying chlorine by vaporization of liquid chlorine in the chlorination process of a bio-ester plasticizer, which comprises a liquid chlorine steel cylinder, a copper pipe, an automatic cutting pneumatic stop valve, an automatic detection alarm instrument for leakage of liquid chlorine, a liquid chlorine pipeline and a vaporizer; the outlet valve of the liquid chlorine steel cylinder is connected with the automatic cut-off pneumatic stop valve through a copper pipe; the automatic cut-off pneumatic stop valve is connected with the vaporizer through a liquid chlorine pipeline; and a liquid chlorine leakage automatic detection alarm instrument is arranged beside the automatic cut-off pneumatic stop valve, and the automatic cut-off pneumatic stop valve is interlocked with the liquid chlorine leakage automatic detection alarm instrument to be automatically closed when alarming. The utility model discloses but in chloro environmental protection plasticizer production process automated inspection liquid chlorine leak and cut off liquid chlorine steel bottle liquid chlorine and supply with, solved among the prior art because of copper pipe leakage or vaporizer pipeline leak cause the problem of safety in production accident.
Description
Technical Field
The utility model relates to an organic chemical products bio-ester plasticizer apparatus for producing, concretely relates to bio-ester plasticizer chlorination process liquid chlorine vaporization supplies chlorine automatic cutout device.
Background
At present, in the production process of the chlorinated environment-friendly plasticizer of fatty acid methyl ester, liquid chlorine is vaporized and supplied to chlorine by a liquid chlorine steel cylinder, and the chlorine is input into a vaporizer through a copper pipe for gasification and then enters a workshop for use. In the prior art, a stop valve is commonly adopted between a copper pipe and a pipeline connected to a gasifier to control and cut off the liquid chlorine supply of a steel cylinder, and the existing defects are as follows: when copper pipe leakage or vaporizer pipeline leakage appear, can only carry out the liquid chlorine that the stop valve was closed in order to cut off the steel bottle to the manual work through wearing protective mask, the drawback of this kind of operation is that speed is slow and dangerous very big, in case leak seriously, personnel do not in time close the stop valve, cause the safety in production accident easily. Therefore, there is a need for an automated device that can automatically and quickly detect leaks and automatically shut down the supply of liquid chlorine cylinders in an emergency.
Disclosure of Invention
The utility model aims at providing a can realize that automatic short-term test leaks and automatic emergency closes the biological ester plasticizer chlorination process liquid chlorine vaporization that liquid chlorine steel bottle supplied with and supplies chlorine automatic cutout device, makes can leak, automatic cutout liquid chlorine steel bottle liquid chlorine supply by automated inspection liquid chlorine in the chlorinated environmental protection plasticizer production process, solves among the prior art because of copper pipe leakage or vaporizer pipeline leak the problem that causes the safety in production accident.
In order to realize the aim, the automatic cutting device for supplying chlorine by vaporizing liquid chlorine in the chlorination process of the bio-ester plasticizer comprises a liquid chlorine steel cylinder 1, a copper pipe 2, an automatic cutting pneumatic stop valve 3, an automatic detection alarm instrument 4 for liquid chlorine leakage, a liquid chlorine pipeline 5 and a vaporizer 6; the outlet valve of the liquid chlorine steel cylinder 1 is connected with the automatic cut-off pneumatic stop valve 3 through a copper pipe 2; the automatic cut-off pneumatic stop valve 3 is connected with the vaporizer 6 through a liquid chlorine pipeline 5; the automatic cut-off pneumatic stop valve 3 is provided with a liquid chlorine leakage automatic detection alarm 4 beside the automatic cut-off pneumatic stop valve, and the automatic cut-off pneumatic stop valve 3 is interlocked with the liquid chlorine leakage automatic detection alarm 4 to be automatically closed when alarming.
The utility model discloses biological ester plasticizer chlorination process liquid chlorine vaporization supplies chlorine automatic cutout device has following technical characterstic and beneficial effect: the automatic detection of the liquid chlorine leakage and the automatic cutting off of the liquid chlorine supply of the liquid chlorine steel cylinder can be effectively realized, and the safety production accidents caused by the leakage of a copper pipe or the leakage of a vaporizer pipeline are avoided; secondly, simple structure, low manufacturing and maintenance cost, convenient and reliable use.
Drawings
FIG. 1 is a schematic structural view of an automatic cutting device for supplying chlorine by vaporization of liquid chlorine in the chlorination process of bio-ester plasticizers.
Reference numerals: the device comprises a liquid chlorine steel cylinder 1, a copper pipe 2, an automatic cut-off pneumatic stop valve 3, a liquid chlorine leakage automatic detection alarm 4, a liquid chlorine pipeline 5 and a vaporizer 6.
Detailed Description
The automatic cutting device for supplying chlorine by vaporization of liquid chlorine in the chlorination process of bio-ester plasticizer according to the present invention will be described in detail with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, the automatic cutting device for supplying chlorine by vaporization of liquid chlorine in the chlorination process of bio-ester plasticizer of the present invention comprises a liquid chlorine steel cylinder 1, a copper pipe 2, an automatic cut-off pneumatic stop valve 3, an automatic detection alarm instrument 4 for leakage of liquid chlorine, a liquid chlorine pipeline 5 and a vaporizer 6; the outlet valve of the liquid chlorine steel cylinder 1 is connected with the automatic cut-off pneumatic stop valve 3 by a copper pipe 2; the automatic cut-off pneumatic stop valve 3 is connected with the vaporizer 6 by a liquid chlorine pipeline 5; the automatic cut-off pneumatic stop valve 3 is provided with a liquid chlorine leakage automatic detection alarm 4 beside the automatic cut-off pneumatic stop valve, and the automatic cut-off pneumatic stop valve 3 is interlocked with the liquid chlorine leakage automatic detection alarm 4 to be automatically closed when alarming.
When the device works, after an outlet valve of the liquid chlorine steel cylinder 1 and the stop valve 3 are opened, liquid chlorine enters the vaporizer liquid chlorine pipeline 5 through the copper pipe 2 and finally reaches the vaporizer 6 for vaporization; once the automatic liquid chlorine leakage detection alarm 4 arranged beside the automatic cut-off pneumatic stop valve 3 detects that the peripheral chlorine content reaches 1PPM, the automatic cut-off pneumatic stop valve 3 interlocked with the automatic liquid chlorine leakage detection alarm 4 can automatically cut off the liquid chlorine supply.
