Abstract
The utility model discloses a safe discharging device of a CNG hydraulic sub-station skid, which relates to a device that can safely discharge the residual fuel gas in a hydraulic oil tank of the CNG (compressed natural gas) hydraulic sub-station skid. The design proposal is that the device comprises an air filter, a discharging pipe and a small flange, a short pipe and a big flange connected with the bottom of the discharging pipe, and a reinforcing rib between the surface of the big flange and the short pipe. The key point is that a flame arrester is arranged on the discharging pipe at the bottom of the air filter. The safe discharging device has the advantages that the residual natural gas can be safely discharged by the discharging device, thus effectively preventing the external combustion source from entering into the hydraulic skid and guaranteeing the safety of the system.
Description
Technical field
The utility model relates to a kind of CNG(compressed natural gas) but the device of remaining combustion gas safety dumping in the hydraulic oil container of hydraulic pressure substation prying body.
Background technique
Existing natural gas automobile secondary gas filling station comprises compressed natural gas conveyor system (source of the gas CNG trailer) and natural gas automobile secondary gas filling station fixed point aerator (CNG hydraulic pressure substation prying body), and CNG hydraulic pressure substation prying body safety bleeding device is installed on this prying body top and be connected with hydraulic oil container.
At present, prying body safety bleeding device in CNG hydraulic pressure substation mainly contains: top exhaust stack, air-strainer and relevant flange connector etc.
The natural gas automobile secondary gas filling station aerator is in to gas combustion automobile aerating process, when carrying out the oil return link, small amounts of natural gas is arranged along with hydraulic oil turns back in the fuel tank, through notes oil return operation repeatedly, the part rock gas has been gathered on top in fuel tank, accumulate to a certain degree and diffuse release pressure by the safety bleeding device.This device deficiency is: after gathering certain hour formation certain pressure, rock gas in the fuel tank just diffuses, this just illustrates in considerable time, the upper space of fuel tank exists rock gas, in case burning things which may cause a fire disaster appears in the space outerpace of prying body, just be easy to enter fuel tank, cause blast and fire by exhaust stack.
Summary of the invention
The utility model is to diffuse the device of remaining combustion gas for the safety that a kind of safer CNG hydraulic pressure substation prying body is provided.
The design proposal that realizes above-mentioned purpose is: this device includes air-strainer, the little flange that exhaust stack and its underpart link, short tube and big flange, and the stiffening rib of big flange surface and short tube outer room, mainly be on the exhaust stack of air-strainer bottom, flame trap to be installed.
The beneficial effects of the utility model are: the remaining rock gas in the fuel tank can diffuse safely by this bleeding device, effectively stops outside burning things which may cause a fire disaster to enter in the hydraulic pressure prying body, has guaranteed security of system.
Description of drawings
Accompanying drawing 1 is existing CNG hydraulic pressure substation prying body safety bleeding device.
Accompanying drawing 2 is the CNG hydraulic pressure substation prying body safety bleeding device after improving.
Embodiment
Existing CNG hydraulic pressure substation prying body safety bleeding device shown in Fig. 1 is that air-strainer 5 bottoms on top are communicated with exhaust stack 4, exhaust stack 4 bottoms are communicated with short tube 2 by little flange 3, short tube 2 is connected with hydraulic oil container by big flange 1 and connects, and there is stiffening rib 6 on big flange 1 surface with short tube 2 outer rooms.CNG hydraulic pressure substation prying body safety bleeding device after the improvement as shown in Figure 2; Mainly installed flame trap 7 additional on the exhaust stack 4 of air-strainer 5 bottoms, annexation is constant between other little flange 3, short tube 2, big flange 1 and the stiffening rib 6.Flame trap 7 is the explosion-proof crimped ribbon arrester of pipeline, and its Dimensions is DN50, and operation pressure is 0.6MPA, and material is carbon steel CS, has commercially available.
