Model utility content
Problem to be solved in the utility model be to provide a kind of employment few, safely, do not have the BOG of noise environmental protection to diffuse recovering device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of LNG storage tank BOG diffuses recovering device, comprise pressure transducer, the automatic recovery solenoid valve, empty warm vaporizer, fuel gas pressure-regulating box, connecting tube and PLC, LNG storage tank diffusion mouth is located at by described pressure transducer, LNG storage tank diffusion mouth the automatic recovery solenoid valve, empty warm vaporizer, fuel gas pressure-regulating box is linked in sequence successively by connecting tube, fuel gas pressure-regulating box is connected with gas ductwork, pressure transducer gathers the pressure of LNG storage tank diffusion mouth, pass to PLC, PLC controls the automatic recovery solenoid valve and opens and closes.
The two ends of described the automatic recovery solenoid valve are parallel with automatic relief solenoid valve, described in diffuse solenoid valve and be connected with described PLC.
The two ends of described the automatic recovery solenoid valve are parallel with machinery and diffuse assembly.
The two ends of described the automatic recovery solenoid valve are parallel with manual drain valve.
Hand stop valve is equipped with between described LNG storage tank diffusion mouth and pressure transducer and between LNG storage tank diffusion mouth and the automatic recovery solenoid valve.
The advantage that the utility model has and good effect are: the utility model utilizes PLC automatic control system on-line monitoring BOG pressure and controls the keying of the automatic recovery solenoid valve and the BOG gas of recovery is transported to gas ductwork through empty temperature vaporizer, and be equivalent to be reduced noise by sky temperature vaporizer through the BOG gas of empty temperature vaporizer, be equivalent to an easy baffler, this device is both safe and reliable, again environmental protection and economy; Diffuse solenoid valve, machinery diffuses assembly and manual drain valve further increases the Security of this device; Close diffusion mouth when hand stop valve facilitates fault to keep in repair equipment.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure:
1. machinery diffuses assembly, 2. automatic relief solenoid valve, 3. manual exhaust valve, 4. the automatic recovery solenoid valve, 5. empty temperature vaporizer, 6. fuel gas pressure-regulating box, 7. pressure transducer, 8.PLC.
Embodiment
Now with reference to the accompanying drawings embodiment of the present utility model is described, as shown in Figure 1, a kind of LNG storage tank BOG diffuses recovering device, comprise pressure transducer, the automatic recovery solenoid valve, empty warm vaporizer, fuel gas pressure-regulating box, connecting tube and PLC, LNG storage tank diffusion mouth is located at by described pressure transducer, LNG storage tank diffusion mouth the automatic recovery solenoid valve, empty warm vaporizer, fuel gas pressure-regulating box is linked in sequence successively by connecting tube, fuel gas pressure-regulating box is connected with gas ductwork, pressure transducer gathers the pressure of LNG storage tank diffusion mouth, pass to PLC, PLC controls the automatic recovery solenoid valve and opens and closes.
In order to improve Security further, the two ends of described the automatic recovery solenoid valve are parallel with automatic relief solenoid valve, described in diffuse solenoid valve and be connected with described PLC.
The two ends of described the automatic recovery solenoid valve are parallel with machinery and diffuse assembly.
The two ends of described the automatic recovery solenoid valve are parallel with manual drain valve.
Conveniently close diffusion mouth during equipment failure to keep in repair other parts, between described LNG storage tank diffusion mouth and pressure transducer and between LNG storage tank diffusion mouth and the automatic recovery solenoid valve, be equipped with hand stop valve.
Working principle: when PLC control system detects the ceiling value of pressure sensor signal higher than setting, control system open the automatic recovery solenoid valve at this moment BOG gas be transported in fuel gas pressure-regulating box through sky temperature vaporizer and carry out pressure regulation, then enter gas ductwork;
If now PLC control system detects pressure transducer force value still higher than setting pressure height in limited time, PLC control system opens automatic relief solenoid valve by unnecessary BOG evacuate air;
If BOG pressure also in lasting rising and reach machinery diffuse module sets diffuse pressure time, machinery diffuses assembly and automatically opens discharge BOG gas;
As long as whole system the automatic recovery solenoid valve is just enough to unnecessary BOG gas consumption to be fallen in most cases, and diffuse assembly and automatic relief solenoid valve without uncapping machine tool, because the gas consumption of gas ductwork is enough to the BOG gas consuming storage tank generation, doing so avoids waste resource, it is to improve Security that automatic relief solenoid valve and machinery diffuse assembly, the backup means of reply special circumstances.
The utility model has following features:
1.PLC control system by gather BOG pressure signal automatic analysis force value when pressure high or too high time automatically open corresponding solenoid valve and control, what adopt due to system is that PLC controls automatically, saves the quantity of duty personnel, saving manpower;
It is accurate that 2.PLC control system gathers numerical value, and reliable performance, avoids human negligence, improves Security;
3.PLC control system logicality is strong, substantially can not produce misoperation, avoid unnecessary danger;
4. needed personnel to go discharge when BOG pressure height in the past, go through manually diffusing to be discharged in air, at this moment exhaust noise is quite large, 80 ~ 90 decibels can be reached, just can hear ear-piercing sound far away, and BOG gas has been transported in gas ductwork through sky temperature vaporizer with regard to automatic when BOG does not also reach and diffuses pressure by device, the BOG gas noise through sky temperature vaporizer is quite little, be equivalent to a baffler, the appearance that noise is general about 40 ~ 50 decibels.Thus reduce the pollution of noise, improve Environmental security grade;
5., owing to being automatically control unnecessary BOG gas to be transported to endlessly in gas ductwork to go to avoid personnel and open discharge frequently, compare and use the equipment of BOG compressor compresses recycling to save sizable cost (comprising time cost and human cost);
6. the diffusion system that this device compares storage tank itself only increases two solenoid valves, a sky temperature vaporizer, with some pipelines, compare other modes to need to add knock out drum, compressor etc. and save a large amount of fund costs, and the simple and convenient maintenance of native system structure.
Above embodiment of the present utility model has been described in detail, but described content is only preferred embodiment of the present utility model, can not by artificial for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
