Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figures 1 and 2, the structural representation of a kind of gas turbine rock gas front device that provides for the utility model, comprise domain 8, be provided with at least one two-stage separated type filter 9 on domain 8, pipeline is connected with isolation ball valve 4 respectively in the import of two-stage separated type filter 9 and outlet port.On two-stage separated type filter 9, safety valve 7 is housed, the Set pressure of safety valve 7 can be set as the case may be, when operating pressure is higher than the Set pressure of safety valve 7, safety valve 7 will be opened the pressure that discharges in the two-stage separated type filter 9, guarantees the security of operation of whole pipeline and two-stage separated type filter 9.Top and bottom at two-stage separated type filter 9 are equipped with fast-opening blind 1 and sewage draining valve 6 respectively.In the present embodiment, having placed 9, one of two two-stage separated type filters on domain 8 uses another then standby.The isolation ball valve of two two-stage separated type filter 9 inlets links to each other in twos, connects inlet ductwork more simultaneously, and the isolation ball valve in outlet port also is same Placement, can realize the online switching of two filters like this by the operation of isolation ball valve.
Be illustrated in figure 3 as two-stage separated type structure of filter schematic representation of the present utility model, comprise cylindrical shell 10, in cylindrical shell 10, be provided with dividing plate 11 inside of cylindrical shell 10 is divided into upper chamber 12 and lower chamber 13, cyclone tube-type discrete device 14 is housed in lower chamber 13, and cyclone tube-type discrete device 14 is connected at the coagulation type filter core 15 in the upper chamber 12.Rock gas enters and is introduced into cyclone tube-type discrete device 14 behind the filter and carries out separating treatment, and then filters through coagulation type filter core 15, and cyclone tube-type discrete device 14 is combined the two-stage separating treatment that realizes rock gas with coagulation type filter core 15.The principle of this two-stage separated type filter is:
First order tornadotron separates: utilize the gravity separation principle, the rock gas that enters filter enters tornadotron from inlet ducts and carries out spiral centrifugal motion, under the centrifugal action that produces, because solid particle, liquid drop are different with specific gravity of natural gas, most oarse-grained solid impurity particle and liquid drops are separated.
Second level coagulation type filer element type filters: the coagulation type filter core equally both can filter solid impurity, also can remove liquid impurity.Flow into the second level filtrating equipment of being formed by the coagulation type filter core through the rock gas after the preliminary cleaning of tornadotron, solid particle polluter separates with rock gas by the filtration of filter core, liquid impurity produces cohesion on the coacervate of cartridge surface, accumulate big drop and flow under the influence of gravity into cylindrical shell bottom and collect discharging.By the separating and filtering of coagulation type filter core, can remove minor diameter solid particle residual in the rock gas, and the fog-like liquid impurity in the rock gas is condensed, solid impurity and liquid impurity are removed to greatest extent.
Simultaneously, because the cyclone tube-type filter has been removed oarse-grained solid impurity, alleviated the load of back level filter core greatly, the working life of having improved filter core greatly.Cyclone tube-type discrete device 14 produces and can onlinely discharge after impurity is pooled to the bottom, and the tornadotron element need not to change or safeguard.Adopt tornadotron and coagulation type filter core double-filtration mode, guaranteeing that rock gas obtains efficiently, in the high Precision Processing, improving usage ratio of equipment greatly.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, the first high liquid level warning switch 5 is installed in lower chamber 13, the second high liquid level warning switch 2 and high high liquid level warning switch 3 is installed in upper chamber 12.After separating, the liquid impurity that contains in the rock gas collects in the bottom of each chamber in the two-stage resolution element of filter, because the rock gas in the upper chamber directly is admitted to the combustion machine after treatment, must carry out more strict monitoring to the liquid stock in the upper chamber, therefore in lower chamber 13, need to install 1 cover high liquid level warning switch, and in upper chamber 12, needing to install 1 cover high liquid level warning switch and the high high liquid level warning switch of 1 cover, the liquid-level switch signal all can insert gas turbine control system and be used for the filter liquid level is carried out remote monitoring.
Differential pressure switch is equipped with in import and outlet port at two-stage separated type filter 9 respectively.Alarm signal can insert gas turbine control system and be used for filter pressure reduction is carried out remote monitoring, produces the high alarm signal of pressure reduction during plugged filter, reminds operator's renew cartridge more in time.Whole module need not the special messenger guard when operation, alarm signal all is transferred to turbine control system and carries out remote monitoring.
Working procedure of the present utility model is: after the rock gas process filter inlet isolation ball valve 4 from the upstream, enter the lower chamber 13 of separator immediately, rock gas enters cyclone tube-type discrete device 14 from inlet ducts and carries out spiral centrifugal motion, under the centrifugal action that produces, because solid particle, liquid drop are different with specific gravity of natural gas, most oarse-grained solid impurity particle and liquid drops are separated.
After cyclone tube-type discrete device 14 in the natural gas via lower chamber 13 carries out separating treatment, can get rid of large particle solid impurity and liquid impurity, enter second level coagulation type filter core 15 then.Solid particle polluter separates with rock gas by the filtration of filter core, and liquid impurity produces cohesion on the coacervate of cartridge surface, accumulates big drop and flows under the influence of gravity into cylindrical shell bottom and collect discharging.By the separating and filtering of coagulation type filter core, can remove minor diameter solid particle residual in the rock gas, and the fog-like liquid impurity in the rock gas is condensed, solid impurity and liquid impurity are removed to greatest extent.
After rock gas after handling through the second level leaves filter, can be delivered directly to gas turbine by pipeline and burn.
The liquid and the solid impurity that are separated in the chamber about filter all are pooled to cavity bottom, be accumulated to a certain degree, liquid-level switch is reported to the police, and control signal feeds back to control system and reports to the police then, reminds the operations staff that filter is carried out manual blowdown.
All design has an inlet outlet pressure differential switch on every filter, and differential pressure switch can send the high alarm signal of pressure reduction to control system when causing that pressure reduction raises when filter core stops up, and reminds operations staff's renew cartridge more in time.Because the utility model adopts one to open a configuration mode that is equipped with, and all be provided with isolation ball valve before and after every filter, so when filter needs more renew cartridge, can switch to the operation of another filter by the operation of valve is online, and not influence the normal operation of system.
