The main performance feature of existing booster station is, pressure-increasing machine should be worked under its suction pressure is equal to or less than the state of supply gas pressure all the time.And existing booster station often is lower than pressure-increasing machine design suction pressure because of being subjected to various factors to influence supply gas pressure, thereby causes booster station throughput to reduce, even crosses low the stopping production because of supply gas pressure.
The content of model utility:
The purpose of this utility model provides the station for enhancing gas pressure that a kind of energy is stablized supply gas pressure, solves present station for enhancing gas pressure because of the not enough problem that causes throughput to descend of supply gas pressure.
Concrete scheme of the present utility model is: create the station for enhancing gas pressure that a kind of energy is stablized supply gas pressure, it comprises pipeline, filter, flowmeter, pressure gauge, be responsible for gate valve, desulfurizing tower, knock out drum, tower-entering valve, tower-outlet valve, tank-outlet valve, pressure governor, the terminal pressure-measuring meter, pressure-increasing machine, its key is: be parallel with booster body on person in charge's gate valve, described booster body has the arm of two parallel connections, wherein on an arm arm gate valve is installed, and be provided with pressure gauge or two of arm gate valve, on another arm, pressurized machine is installed, inlet at pressurized machine is equipped with pressure gauge, in manometric front gate valve is installed.
The pressurized machine of the new configuration of the utility model adopts a stage compressor, and compression ratio is set at about 2.3, and cost is low.
The utility model makes supply gas pressure and air demand satisfy booster station unit requirements of one's work all the time by booster body is set on main line, guarantees the throughput of booster station.
The beneficial effects of the utility model are:
1. under the situation of supply gas pressure deficiency, can guarantee the ordinary production of booster station by booster body.
2. the booster body cost that is disposed is low, less than 5% of booster station gross investment.
3. the pressurized machine energy consumption of new configuration is low, its power of motor less than supporting pressure-increasing machine power, make booster station under the not enough situation of supply gas pressure, bring increasing substantially of throughput with less energy consumption.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Please see Figure 1, the utility model is by pipeline 1, filter 2, flowmeter 3, pressure gauge P1, be responsible for gate valve Z1, desulfurizing tower 4, knock out drum 5, tower-entering valve Z4, tower-outlet valve Z5, tank-outlet valve Z6, pressure governor 6, terminal pressure-measuring meter P5 and P6, pressure-increasing machine 7,8,9 and booster body form, their annexation is, filter 2 is installed on pipeline 1, flowmeter 3, pressure gauge P1, be responsible for gate valve Z1, tower-entering valve Z4, pipeline 1 one ends are connected with the inlet of desulfurizing tower 4, the tower-outlet valve Z5 that the outlet of desulfurizing tower 4 reaches in the pipeline by the road is connected with the inlet of knock out drum 5, tank-outlet valve Z5 is installed on the output pipe of knock out drum 5, pressure governor 6, terminal pressure-measuring meter P5 and P6 are parallel with three pressure-increasing machines 7 on the outlet end pipeline of pressure governor 6,8,9.On person in charge's gate valve Z1, be parallel with booster body, described booster body has the arm of two parallel connections, wherein on an arm arm gate valve Z3 is installed, and be provided with pressure gauge P4 or P3 or two of arm gate valve Z3, pressure-increasing machine 10 is installed on another arm, inlet at pressurized machine 10 is equipped with pressure gauge P2, in the front of pressure gauge P2 gate valve Z2 is installed.
Be the booster body that supply gas pressure is carried out supercharging in the dashed rectangle among Fig. 1, wherein one of arm gate valve Z3 is provided with pressure gauge P4, and the other end is provided with pressure gauge P3, also pressure gauge P3 can be arranged on the main line of tower-entering valve Z4 front.
Working principle of the present utility model is: as supply gas pressure P1 during less than the design suction pressure P6 of former supercharging unit, start pressurized machine 10, close the gate valve Z1 that former air inlet is responsible for simultaneously, the natural gas flow that enters the station enters the supercharging bypass from former suction tude A1 point, after supercharging, enter former supply air line from A2.10 design suction pressure P2 are 48% of former supercharging unit maximum continuous boost P6 because of pressurized machine, the exhaust pressure of pressurized machine 10 equals 1.1 times of former supercharging unit design suction pressure P6, and the design discharge capacity of pressurized machine 10 equals the overall design air inflow of former three pressure-increasing machines; So, being not less than when suction pressure in 48% the scope of former supercharging unit maximum continuous boost P6, the exhaust pressure of pressurized machine 10 and discharge capacity can both satisfy the requirement of former pressure-increasing machine to suction pressure and air inflow.
This booster body also has voltage stabilizing function, the designing and arranging atmospheric pressure P3 of pressurized machine 10 equals 1.1 times of supercharging unit maximum continuous boost, air-flow L2 after pressurized machine 10 superchargings is by desulfurizing tower 4, and knock out drum 5 is transferred to the required maximum continuous boost P6 of former supercharging unit by pressure governor 6.As gas supply line supply gas pressure P1 during greater than pressurized machine 10 maximum continuous boost P2 (equaling 0.48P6), can regulate by gate valve Z2 and enter the pressure-increasing machine air-flow, make P2 equal 0.48P6.The trace deviation can be regulated with gate valve 3.Observe if P3 greater than 1.1 times of P6, opens gate valve Z3 simultaneously gradually from pressure gauge P3, form loop air-flow L4, the air-flow L2 that enters the air feed person in charge reduces, and equals 1.1 times of P6 up to P3.
