Description
Technical field
The present invention is a kind of heating means and device of leading type pressure regulator valve of compressed natural gas leading type pressure regulator valve pilot valve.Relate to valve, the fluid heater generally with thermal source, heat exchange and pipe-line system technical field.
Background technique
Along with the continuous lifting of national economy, domestic every profession and trade is also growing with each passing day to the demand of rock gas.Utilizing high pressure gas pipeline transport gas, is the sole mode of a large amount of transport gas in land, and for the long distance delivery of rock gas, be all generally adopt high pressure pipe line, pressure is up to 8-10MPa.Natural gas user mainly can be divided into industrial user and domestic consumer, these users are usually in city, in order to the facility that urban safety and user use, natural gas via needs to carry to downstream urban subscriber after step-down process after being carried by high pressure long distance pipeline.In natural gas transport process, each urban construction Natural Gas Station field can be adjoined along long defeated high pressure pipe line, the task of Natural Gas Station field is exactly the demand according to downstream user, the Pressure Drop of rock gas is low to moderate 1-2MPa, within the scope of even lower safety pressure, then divide and be defeated by downstream user.Therefore, Natural Gas Station field is requisite connecting link between rock gas seedbed and terminal use.
At present, domestic Natural Gas Station field all adopts sledge formula pressure governor to carry out pressure adjustment to pressurized gas, and pressure regulation sledge mainly contains three parts and forms: Emergeny Cutoff Valves, electric pressure-regulating valve and monitor valve.Emergeny Cutoff Valves mainly plays a part to ensure Gas Stations safety, the emergency cut-off source of the gas when having a mind to outer generation, prevents the disaster such as to detonate on fire from occurring; Pressure regulator valve is based on leading type pressure regulator valve, and its effect is the safety pressure scope Pressure Drop of the high-pressure natural gas from high-pressure gas pipelines being low to moderate downstream user requirement; Monitor valve is used to monitor the gas pressure after pressure regulator valve step-down; usual meeting sets a monitoring value according to the Production requirement of downstream user; when the gas pressure after step-down is lower than this value; monitor valve is not had an effect; when downstream gas pressure has exceeded setting value; then monitor valve will be closed automatically, to ensure the safety of gas downstream pipeline.
Three grades of Valve controlling of sledge formula pressure adjusting structure are while realizing gas pressure adjustment, can also the safety of effective guarantee downstream user, but pressurized gas are via after electric pressure-regulating valve, its pressure reduces rapidly, " Joule-Thomson " effect (also referred to as " throttle effect ") will be there is, suddenly falling namely along with pressure, gas temperature will sharply reduce.In Gas Stations actual motion, gas is before and after the step-down of pressure regulation sledge, and the temperature difference can reach more than 10 DEG C.Because rock gas forms primarily of short hydrocarbon, the existence of a small amount of moisture makes rock gas forming mixture of ice and water lower than when 0 DEG C, causes " ice blocks up " of leading type pressure regulator valve and gas downstream transfer line." ice blocks up " not only can affect the normal production run of Gas Stations, but also is the major safety risks of Gas Stations and gas downstream transfer line.In order to eliminate " ice blocks up ", currently used method mainly physical heating, as installed electric-heating belt, adopting hot water sleeve pipe to downstream line heating etc. on pressure regulation sledge equipment.But hidden danger that these physical heating methods can not fundamentally be eliminated " ice blocks up ", also can consume a large amount of energy.Therefore, be necessary that exploitation one is specifically applied to Natural Gas Station field voltage adjusting device, and there is the heating technology of environmental protection, the advantage such as energy-conservation, thoroughly eliminate " ice blocks up " phenomenon produced in pressure regulation process.
Summary of the invention
The object of the invention is to invent a kind of movement-less part, non-maintaining, the heating means and the device that there is higher reliability, do not need power supply, there is the leading type pressure regulator valve of Good Security.
The present invention is based on vortex tube energy separation technology, a small amount of pressurized gas are made to flow through eddy current guide combustion heater (VTGH), utilize vortex tube to pressurized gas step-down, pressure reduction can be converted to heat energy simultaneously, and utilize this energy heats guide combustion gas, thus eliminate pilot valve decompression " ice blocks up " problem of leading type pressure regulator valve.At present, domestic Natural Gas Station field all adopts sledge formula structure to carry out pressure adjustment to high-pressure natural gas, then downstream user is flowed to, in pressure adjustment process, " throttle effect " is inevitable, therefore in the season that temperature is lower, " throttle effect " very easily causes field, station regulator that " ice blocks up " phenomenon occurs." ice blocks up " impact station normal production and operation in field on the one hand is also major safety risks on the other hand.For the problems referred to above, invent a kind of device and effectively eliminate equipment because " throttle effect " causes " ice blocks up " phenomenon.This device movement-less part, non-maintaining, there is higher reliability; Secondly, do not need electric equal energy source, the equivalent risk that detonates on fire can be exempted, there is good Safety performance.This device, in the application of Gas Stations, can eliminate the potential safety hazard caused because of " ice blocks up " phenomenon.
The high pressure related in the present invention long defeated Natural Gas Station field sledge formula regulator as shown in Figure 1, divides between the suction port of field, defeated station and exit at high-pressure natural gas and is connected in series Emergeny Cutoff Valves 3, leading type monitor valve 1 and leading type pressure regulator valve 2 successively; Be front with the suction port of Natural Gas Station field, the pilot valve pilot valve 4 of leading type monitor valve 1 connects the pipeline before leading type monitor valve 1, pick out exit again after being connected with the pilot valve pilot valve 5 of leading type pressure regulator valve 2, and the pilot valve pilot valve 5 of leading type pressure regulator valve 2 is connected with the pipeline before leading type pressure regulator valve 2 simultaneously.In Fig. 1, P1 and P3 is respectively suction pressure and the Outlet pressure that high-pressure natural gas divides field, defeated station, and the size of P1 depends on the discharge pressure of upstream line, and P3 sets according to downstream user demand.P1 and P3 is not fixed value, usually can a metastable interval fluctuation.Sledge formula regulator working principle is as follows:
First, according to downstream user demand, the pressure P 2 capping value after leading type monitor valve 1, in sledge formula regulator, under normal circumstances, operating valve is to downstream pipe air feed, because its setting value is higher, therefore leading type monitor valve 1 is in complete opening state always.Once leading type pressure regulator valve 2 breaks down or because of other reason, P2 raises, during the pressure set points to leading type monitor valve 1 to be lifted, leading type monitor valve 1 is taken over leading type pressure regulator valve 2 and is carried out pressure regulation, the pressure that a little higher than client is given at short notice of P2 now.Leading type pressure regulator valve 2 is also called operating valve, is the device to P1 step-down in sledge formula regulator, and according to the size of P1 and P2, leading type pressure regulator valve 2 regulates its aperture automatically, to realize safety adjustable-pressure.Emergeny Cutoff Valves 3 is called safety cut-off valve again, it is the safe match equipment generally adopted in gas pipeline engineering, Main Function is by arranging ZCR gas emergency cut-off valve, can in the indoor centralized control of center-control, when there is dangerous or other urgency, the pipeline air feed of Remote emergency cut-off scene of the accident.Usual Emergeny Cutoff Valves 3 is open type pulse trigger type type solenoid valves, has accident self-locking and hand reset function.
The heating means of leading type pressure regulator valve as shown in Figure 2.It is: will originally should be incorporated in two-channel pilot combustion heater 9 via the high-pressure natural gas of leading type pressure regulator valve 2, pressure reduction between P1 and P3 can be converted into heat energy, cold energy while step-down by gas in two-channel pilot combustion heater 9, namely the original energy transformed in leading type pressure regulator valve 2 is carried out shunting, transforms, is separated, transform with separation energy process at this, cold energy is compared with the cold of pipeline itself, a just very little part, can directly to release downstream line, and the energy of heat is accumulated in two-channel pilot combustion heater 9.First air guide enters in two-channel pilot combustion heater 9 through first air guide Inlet ball valve 8, with the hot gas generation heat exchange in two-channel pilot combustion heater 9, pilot gas temperature is raised, form heating circuit, respectively pilot valve pilot valve I 4 and pilot valve pilot valve II 5 are heated via leading type monitor valve pilot valve heating circuit 10 and leading type pressure regulator valve pilot valve heating circuit 11, reach " ice the is stifled " phenomenon eliminated pilot valve pilot valve I 4 and pilot valve pilot valve II 5 and produce because of " throttle effect ".
The present invention's device used is: at the long defeated natural gas transmission pipeline suction port of high pressure and be connected in series Emergeny Cutoff Valves 3, leading type monitor valve 1 and leading type pressure regulator valve 2 between air outlet successively; Between Emergeny Cutoff Valves 3 and leading type monitor valve 1, have a pipeline to connect two-channel pilot combustion heater 9, Ling You mono-tunnel through first air guide Inlet ball valve 8 points of two-way directly receives in two-channel pilot combustion heater 9 through eddy current loop 6; Leading type monitor valve 1 and leading type pressure regulator valve 2 are connected air outlet successively, and pilot valve I 4 and the pilot valve II 5 of leading type monitor valve 1 and leading type pressure regulator valve 2 are connected heating circuit 10 and the heating circuit 11 of two-channel pilot combustion heater 9 separately simultaneously; Leading type monitor valve 1 picks out gas port after being connected with pilot valve II 5 with the pilot valve I 4 of leading type pressure regulator valve 2; Two-channel pilot combustion heater 9 picks out gas port through VTGH vent ball valve 7.
The structure of device, be the equal of, in sledge formula regulator (placing Emergeny Cutoff Valves 3, leading type monitor valve 1 and leading type pressure regulator valve 2 between suction port and the air outlet in turn) bypass of Gas Stations, the shunting means of one tunnel containing two-channel pilot combustion heater 9 has been installed, additional shunting means does not change former sledge formula structure, only plays the effect of heating pilot valve I 4 and pilot valve II 5.
Wherein:
As shown in Figure 3, it is the vortex tube for leading type pressure regulator valve " ice blocks up " the improvement of problem in sledge formula regulator in the present invention, the i.e. right hot-air heater of eddy current guide (VTGH) to two-channel pilot combustion heater 9.The same with traditional vortex tube, single channel eddy current guide combustion heater (VTGH-SP) and double-channel vortex guide combustion heater (VTGH-DP) can be divided into by the quantity VTGH of heat tunnel, in the present invention, use double-channel vortex guide combustion heater (VTGH-DP).Its formation is: there is the vortex chamber 13 of pressurized gas inlet 12 one end, there is cold junction gas outlet 20 its side, relative opposite side has vortex tube 15 to communicate with vortex chamber 13, and the other end in vortex tube 15 is provided with the modulating valve 18 of vortex tube, and hot junction gas outlet 17 is arranged at the top of this end.
The working principle of VTGH-DP is as follows:
Compressed natural gas is through pressurized gas inlet 12 P
inletenter vortex chamber 13, enter in vortex tube 15 after forming the eddy current of High Rotation Speed.Due to mechanics effect, the eddy current 14 that pressurized gas are formed is along the runner High Rotation Speed of vortex tube 15 tube wall to modulating valve 18 direction of vortex tube, owing to being subject to the effect of vortex tube 15 tube wall frictional force, eddy current 14 speed that pressurized gas are formed die-offs, pressure reduces, produce a large amount of heat energy simultaneously, form the swirl gas 16 along vortex tube tube wall.After the eddy current 14 that pressurized gas are formed arrives the modulating valve 18 of vortex tube, a part of gas is from P
outhot junction gas outlet 17 is discharged, and another part is pushed up back by the modulating valve 18 of vortex tube, along vortex tube 15 center to ejection in the other direction, forms cold back draught 19.In the process of cold back draught 19 to ejection in the other direction, continuous and close vortex tube 15 tube wall there is heat exchange along vortex tube tube wall swirl gas 16, make the temperature along vortex tube tube wall swirl gas 16 more and more lower, the temperature of cold back draught 19 then constantly raises, until reach thermal equilibrium.
Leading type pressure regulator valve heating technology in the present invention does not need to use any extra power, the pressure reduction occurred in two-channel pilot combustion heater 9 can be all the physical process of carrying out in two-channel pilot combustion heater 9 inside to the transfer process of heat energy, there is not chemical reaction, do not need mobile any component yet, do not need to change sledge formula regulator.Do not need to consume any energy, solve by the transformation of energy of pressurized gas " ice blocks up " problem that leading type pressure regulator valve pilot valve under cryogenic conditions produces because of " throttle effect ", eliminate the potential safety hazard of Natural Gas Station field.
After pilot valve pilot valve I 4 and pilot valve pilot valve II 5 are heated in first air guide, directly to be released to downstream line by pressure inlet tube, due to the transformation of energy energy conservation in whole system and two-channel pilot combustion heater 9, the end air flow of releasing in downstream line can not affect the natural gas temperature of downstream trunk line.In heating process, on leading type pressure regulator valve 2, when pressure difference between the pressure P 1 in downstream and P2 changes, throttle effect in pilot valve pilot valve I 4 will change, corresponding, thermal effect in two-channel pilot combustion heater 9 also changes because of the pressure difference change between P1 and P2, this just means the situation of the throttle effect of the heating state meeting adaptive tracing leading type monitor valve 1 of two-channel pilot combustion heater 9, namely the heated condition of two-channel pilot combustion heater 9 is dynamic, its Changing Pattern is determined by the pressure difference before and after leading type monitor valve 1.For second level pressure regulator valve (between P2 and P3), principle is also the same.It is to be noted, although continual eddy current heat is accumulated at the outer wall of vortex equipment, the outside wall temperature of vortex equipment is constantly raised, but this temperature rise is limited, infinitely can not raising, according to regulating the segregation ratio of vortex tube, its thermal equilibrium temperature being controlled at safety anti-explosive limiting temperature (more than 130 DEG C required by EXP IV).Because, the thermal effect of two-channel pilot combustion heater 9 is a kind of dynamic effect (generation of heat is synchronous dynamic process with exchange), while two-channel pilot combustion heater 9 tube wall temperature raises, between first air guide and hot-fluid gas, heat exchange strongly and efficiently will be carried out simultaneously, add the physical control of vortex tube segregation ratio, make accumulation of heat in two-channel pilot combustion heater 9 and the temperature that reaches cannot surmount safety anti-explosive limiting temperature, ensure the safety that the device security of sledge formula regulator and field, station produce.
Leading type pressure regulator valve pilot valve heating means of the present invention and device, there are energy-saving and environmental protection, without moving member, the major function such as non-maintaining, the VTGH-DP improved based on vortex tube realizes the function that pressure reduction can be converted to heat energy, accurate connection line chart realizes the heat energy that is transformed by VTGH-DP and first air guide realizes heat exchange, and and then heating pilot valve pilot valve I 4 and pilot valve pilot valve II 5, thus eliminate " ice blocks up " phenomenon, for high-pressure natural gas divides the device security of field, defeated station and production safety to provide safeguard.
So advantage of the present invention is:
1) solve leading type pressure regulator valve pilot valve " ice blocks up " problem that high-pressure natural gas divides field, defeated station under microthermal climate condition because throttle effect causes, eliminate the potential safety hazard of voltage adjusting device and the station normal production run in field;
