Description

Technical Field

[0001] The utility model relates to the technical field of gas filling station equipment, in particular to an intelligent automatic purge device. Background Art

[0002] As the construction of gas stations continues to grow, the safe filling of gas dispensers and vehicle gas cylinders has become a considerable challenge. Since the filling medium is a liquefied medium, depending on the different operating ambient temperature conditions, it will cause frost on the surface and inside of the filling muzzle, and even in severe cases, there will be surface ice and ice debris, causing the filling muzzle mechanical parts to be inflexible and the sealant to be damaged, resulting in leakage, posing a safety threat to personnel.

[0003] Traditional technical solutions have the following defects: 1. Manual purging is performed using compressed gas at a certain pressure provided by the equipment, but the effect is poor. Once the seal fails, liquid will be sprayed, causing frostbite to personnel. 2. Purging is performed by heating the filling gun muzzle, but this method is not ideal and poses certain safety risks to explosion-proof areas. Once liquid leaks and vaporizes into gas and mixes with air to reach explosion conditions, the heating temperature will be out of control and too high, which will lead to explosion safety hazards. 3. The flow rate of the purge nozzle is constant and variable speed purging is not possible. Under extreme working conditions, it cannot be fully purged, and the effect is not ideal.

The system closes the needle valve 12 and collects the air moisture content through the humidity sensor 41. If the detected air moisture content is less than or equal to the preset qualified air moisture content of the system, the purge is completed and the operator is prompted; if the detected air moisture content is greater than the preset qualified air moisture content of the system, the above steps are repeated until the qualified end, and the interlock protection release command is issued. The alarm indicator light 32 changes from flashing red to solid green, prompting the staff to complete the purge.

[0078] When the system is in the normal working mode, the liquid filling gun is inserted into the gun barrel assembly 7, and the system detects the gun insertion state through the position sensor 42, and the data detected by the position sensor 42 is transmitted to the central control unit; if the central control unit detects that the gun is not inserted, the safety interlock protection action is executed to prohibit purging; if the central control unit detects the gun insertion state, the control center opens the needle valve 12 and the cylinder motor 18 through the execution control unit, so that the first air pipe 22, the second air pipe 23, the third air pipe 24 and the fourth air pipe 25 enter the rotation purge; firstly, the air source of 0.7MPa (this value is adjustable) is executed Pressure, calculate the compressed air nozzle flow, and perform high-pressure forward 30S (this value is adjustable) high-flow rate purge; then execute 0.7MPa (this value is adjustable) air source pressure, calculate the compressed air nozzle flow (see formula ①), and perform high-pressure reverse 30S (this value is adjustable) high-flow rate purge; execute 0.3MPa (this value is adjustable) air source pressure again, calculate the compressed air nozzle flow, and perform low-pressure forward 30S (this value is adjustable) low-flow rate purge; finally execute 0.3MPa (this value is adjustable) air source pressure, calculate the compressed air nozzle flow, and perform low-pressure reverse 30S (this value is adjustable) low-flow rate purge. The system closes the needle valve 12 and collects the air moisture content through the humidity sensor 41. If the detected air moisture content is less than or equal to the system preset qualified air moisture content, the purge ends and the operator is prompted; if the detected air moisture content is greater than the system preset qualified air moisture content, continue to repeat the above steps until it is qualified and the interlock protection release command is issued. The alarm indicator light 32 changes from flashing red to steady green, prompting the staff that the purge is complete.

[0079] The calculation formula of compressed air nozzle flow rate is as follows:

[0080]

[0081] Among them, Q represents the nozzle flow rate, the unit is cubic meter / second; C represents the nozzle flow coefficient, which is a constant related to the nozzle shape and design and has no unit; A represents the nozzle outlet area, the unit is square meter, ΔP represents the pressure difference of compressed air, the unit is Pascal (Pa); ρ represents the density of compressed air, the unit is kilogram / cubic meter.

[0082] Calculation of the aperture of the spray net of the deicing agent spray nozzle:

[0083] d=(3μQ / (πρV))1 / 3②;

[0084] Among them, d represents the spray particle size, μ represents the viscosity, Q represents the flow rate, ρ represents the density, and V represents the outlet velocity.

[0085] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 On the basis of the structure of the present embodiment, in another embodiment, a distribution valve (not shown in the figure) is arranged on the air inlet stainless steel pipe 11 between the needle valve 12 and the one-way valve 13, and the distribution valve is directly connected to a plurality of explosion-proof solenoid valve groups 15 through a pipeline, so that the high-pressure gas entering the needle valve 12 directly enters the plurality of explosion-proof solenoid valve groups 15 through the action of the distribution valve, and then is connected to the rotating platform assembly 6 through a pipeline to achieve purging. In this way, the high-pressure gas does not pass through the deicing agent tank 10, so that the high-pressure gas purged does not carry the deicing agent, which is suitable for the situation where the deicing agent purging is not required.
