Abstract
The utility model aims at providing a refined system unloading ware with fast function of opening, the utility model provides a become by casing, steam inlet, steam outlet, manual atmospheric valve, self emptying valves, steam inlet is located casing one side, steam outlet is located the casing opposite side, steam outlet is two, manual atmospheric valve is located one of them steam -outlet pipe on the road, the self emptying valve position in another steam -outlet pipe on the road. The workman opens manual atmospheric valve, and xylol steam can discharge the xylol condenser through installing manual atmospheric valve blowdown piping, carries out the pressure release, if forget out manual atmospheric valve, the system pressure will rise, and when the system pressure rose the alert value of the limit, the self emptying valve can automatic be opened, and xylol steam can discharge the xylol condenser through installation self emptying valve blowdown piping, carries out the pressure release, has guaranteed the security of production.
Description
Technical field
The utility model relates to field of chemical equipment, particularly relates to a kind of refining system venting device opening function with speed.
Background technology
Dimethylbenzene is widely used in the industries such as coating, resin, dyestuff, ink and makees solvent; Synthon or solvent is done for industries such as medicine, explosive, agricultural chemicals; Also can be used as high octane gasoline component, is the important source material of organic chemical industry.The pitch removing vehicle body can also be used for.Hospital pathology department is mainly used in the transparent and dewaxing of tissue, section.
Interval refining system often criticizes driving, and when adding dimethylbenzene operation, system pressure can rise, and xylene steam can be discharged into dimethylbenzene condenser by blowdown piping.Because each emptying is all manual operation, this is just present in the possibility of operate miss.If forget out atmospheric valve when adding dimethylbenzene, system pressure will rise, and then causes system pressure meeting superelevation, and rupture pressure disc can break, and xylene steam can leak ejection, there is very big potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of refining system venting device opening function with speed, blowdown piping installs automatic air release valve additional, if workman forgets out manual vent valve, system pressure rises and reaches the alert value of high limit, automatic air release valve can be opened automatically, carry out pressure release, ensure that the security of production.
The technical solution of the utility model is: a kind of refining system venting device opening function with speed, it is characterized in that: be made up of housing, steam inlet, steam (vapor) outlet, manual vent valve, automatic air release valve, described steam inlet is positioned at housing side, described steam (vapor) outlet is positioned at housing opposite side, described steam (vapor) outlet is two, described manual vent valve is positioned on one of them steam (vapor) outlet pipeline, and described automatic air release valve is positioned on another steam (vapor) outlet pipeline.
Further, described automatic air release valve is by Stress control.
The beneficial effects of the utility model are: when adding dimethylbenzene, and workman opens manual vent valve, and xylene steam can be discharged into dimethylbenzene condenser by installing manual vent valve blowdown piping, carries out pressure release; If forget out manual vent valve, system pressure will rise, when system pressure is elevated to limit police value, automatic air release valve can be opened automatically, xylene steam can be discharged into dimethylbenzene condenser by installing automatic air release valve blowdown piping, carries out pressure release, ensure that the security of production.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Wherein: 1, housing 2, steam inlet 3, steam (vapor) outlet
4, manual vent valve 5, automatic air release valve
Detailed description of the invention
Below in conjunction with accompanying drawing, brief description is made to detailed description of the invention of the present utility model.
A kind of cis-butenedioic anhydride waste recovery dissolving tank as shown in Figure 1, it is characterized in that: be made up of housing 1, steam inlet 2, steam (vapor) outlet 3, manual vent valve 4, automatic air release valve 5, described steam inlet 2 is positioned at housing 1 side, described steam (vapor) outlet 3 is positioned at housing 1 opposite side, described steam (vapor) outlet 3 is two, described manual vent valve 4 is positioned on one of them steam (vapor) outlet 3 pipeline, and described automatic air release valve 5 is positioned on another steam (vapor) outlet 3 pipeline.
Working method: first steam inlet is connected with dimethylbenzene adding set pipeline, and steam (vapor) outlet is connected with dimethylbenzene condenser, setting automatic air release valve opens pressure automatically, and when adding dimethylbenzene, xylene steam enters venting device, if forget out manual vent valve, system pressure will rise, and when system pressure is elevated to limit police value, automatic air release valve is opened automatically, xylene steam can be discharged into dimethylbenzene condenser by installing automatic air release valve blowdown piping, carries out pressure release.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
Claims (2)
1. open the refining system venting device of function with speed for one kind, it is characterized in that: be made up of housing, steam inlet, steam (vapor) outlet, manual vent valve, automatic air release valve, described steam inlet is positioned at housing side, described steam (vapor) outlet is positioned at housing opposite side, described steam (vapor) outlet is two, described manual vent valve is positioned on one of them steam (vapor) outlet pipeline, and described automatic air release valve is positioned on another steam (vapor) outlet pipeline.
