Abstract
The utility model relates to an unloading pipeline natural gas recovery unit, include the blow -down pipe and install the atmospheric valve on the blow -down pipe, it retrieves ball valve and check valve to have connected gradually through the pipeline on the blow -down pipe of atmospheric valve income gas end, exit end at the check valve has the gas holder through the pipe connection, there is the choke valve through the pipe connection on the jar wall of the left side of gas holder, the export of choke valve is through pipe connection to the natural gas mouth that enters the station, the jar wall mounting has the manometer on the right side of gas holder, a pressure for in the real -time detection gas holder, furthermore, there is the blowoff valve bottom at the gas holder through piping erection. The utility model discloses a blow -down pipe natural gas recovery unit will most natural gas when emptyying the operation retrieves the gas holder, only needs during a small amount of low pressure natural gas discharges the atmosphere, and it is extravagant to reduce the energy.
Description
Technical field
The utility model belongs to the natural gas recycling device technical field of rock gas mother station, particularly a kind of exhausting pipeline natural gas recycling device.
Background technique
During the overhaul of the equipments of current CNG (CompressedNaturalGas) compressed natural gas mother station, need rock gas in emptying device and pipeline, conventional method, for be directly discharged in air by rock gas by exhausting pipeline, causes energy waste.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of exhausting pipeline natural gas recycling device.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of exhausting pipeline natural gas recycling device, comprise blow-down pipe and be arranged on the atmospheric valve on blow-down pipe, the blow-down pipe of atmospheric valve air inlet end is connected with in turn by pipeline and reclaims ball valve and one-way valve, gas holder is connected with by pipeline at the outlet end of one-way valve, the left side tank skin of gas holder is connected with throttle valve by pipeline, the outlet of throttle valve is connected to rock gas ENTRANCE by pipeline, and the right side tank skin of gas holder is provided with pressure gauge, for detecting the pressure in gas holder in real time.
And, there is blowdown valve in the bottom of gas holder by Pipe installing.
Advantage of the present utility model and good effect are:
1, blow-down pipe natural gas recycling device of the present utility model, is recovered in gas holder by most of rock gas during emptying manipulation, only needs a small amount of low pressure natural gas to be discharged in air, reduces energy waste.
2, the utility model reasonable in design, rock gas reuse efficiency is high, is applicable to marketing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of exhausting pipeline natural gas recycling device, as shown in Figure 1, comprise blow-down pipe and be arranged on the atmospheric valve on blow-down pipe, the blow-down pipe of atmospheric valve front end is connected with in turn by pipeline and reclaims ball valve and one-way valve, gas holder is connected with by pipeline at the outlet end of one-way valve, the left side tank skin of gas holder is connected with throttle valve by pipeline, the outlet of throttle valve is connected to rock gas ENTRANCE by pipeline, the right side tank skin of gas holder is provided with pressure gauge, for detecting the pressure in gas holder.
In concrete enforcement of the present utility model, there is blowdown valve in the bottom of gas holder by Pipe installing, can regularly the sediments bottom gas holder be discharged, cleaning gas holder.
Working principle
When equipment normally runs, in Fig. 1, all valves are all in closed condition, when needing emptying, first open and reclaim ball valve and one-way valve, pressurized gas are temporarily stored in gas holder, when reservoir pressure is stablized, close and reclaim ball valve and one-way valve, open atmospheric valve and carry out emptying.When equipment restarts, open throttle valve, reach the object that rock gas is recycled.
Claims (2)
1. an exhausting pipeline natural gas recycling device, comprise blow-down pipe and be arranged on the atmospheric valve on blow-down pipe, it is characterized in that: be connected with in turn by pipeline on the blow-down pipe of atmospheric valve air inlet end and reclaim ball valve and one-way valve, gas holder is connected with by pipeline at the outlet end of one-way valve, the left side tank skin of gas holder is connected with throttle valve by pipeline, the outlet of throttle valve is connected to rock gas ENTRANCE by pipeline, the right side tank skin of gas holder is provided with pressure gauge, for detecting the pressure in gas holder in real time.
