Description
Technical field
The utility model relates to gas turbine fuel supply system, is specifically related to gas turbine blast furnace gas filter.
Background technology
The fuel that is applied at present the gas turbine of domestic iron and steel enterprises is generally blast furnace gas, coke-stove gas and coal gas of converter; Because the inferior quality of coke-stove gas and coal gas of converter, impurity content is higher, easily causes the frequent jams of gas turbine nozzle and filter, the frequent chaser of gas turbine; For fear of this kind of situation, adopt now null value class new technology, only in the time of start, enable coke-stove gas, after the normal startup of gas turbine, just directly cut off coke-stove gas, only pass into blast furnace gas; Yet the calorific value of coke-stove gas is larger than blast furnace gas, for the temperature in gas turbine reaches set point of temperature, now need again the unit interval to pass into more blast furnace gas as fuel.Because the filter circulation area of traditional filtering blast furnace gas is little, dust and steam easily deposit at filter screen place, once stopping up, filter need to dismantle for a long time cleaning, but the filter of use on blast furnace gas pipeline removes and installs at every turn and all needs to carry out sealing propertytest, makes complex installation process.
Summary of the invention
The purpose of this utility model is to provide a kind of gas turbine blast furnace gas filter of exempting from dismounting and easy to clean.
To achieve these goals, the technical scheme that the utility model provides: gas turbine blast furnace gas filter, gas turbine blast furnace gas filter, comprise the valve body being serially connected on blast furnace gas pipeline, be inclined at valve body Shang Lv road, filter cylinder, impeller, brush, blow-off pipe and scavenging conduit, described filter cylinder is fixed in filter road, described brush is arranged on cartridge interior, the bristle of this brush contacts with filter cylinder inwall, described scavenging conduit be arranged on filter road one end and and filter cylinder end connection, described impeller is arranged in scavenging conduit and is connected by rotating shaft with brush, the other end in described filter road is connected by flangeseal, blow-off pipe is through ring flange, blow-off pipe is provided with blowoff valve, blow down valve is installed on scavenging conduit.
The feature of technique scheme is: in needs filter rinsed, close air inlet and the gas outlet of gas turbine blast furnace gas filter, open blowoff valve; On scavenging conduit, access high-pressure air source, owing to being provided with impeller in scavenging conduit, the rotation of high-pressure air source impeller, impeller and brush are coaxial rotation; Now brush will be rotated and swipe filter cylinder, the dust now sticking on filter cylinder can be fast along with high-pressure air source is gone out from blowoff valve together, whole process continues 1 minute, can be clean to cleaning filter, punching is swept after complete only need to shut blow down valve and blowoff valve, and system will work again.Wherein blow down valve and blowoff valve are all stop valve.
As preferred version, in order to guarantee the durable for a long time of cleaning brush, described cleaning brush is the wear-resisting brush of silica gel, because the wear-resisting brushing tool of silica gel has wear-resisting and flexibility, for filter cylinder, there is no destructiveness, and itself has resistance to acids and bases, has advantages of that the life-span is long.
As preferred version, in order to facilitate filter residue and deslagging, the inclination angle of described filter road and valve body is 45 °, when blast furnace gas passes through, inclination angle Yue great Vietnamese side is filter residue and deslagging just like this, but when inclination angle is excessive, the infringement in gas Dui Lv road is comparatively serious, 45 ° of position the bests of empirical tests.
Accompanying drawing explanation
Fig. 1 is the structural representation of the gas turbine blast furnace gas filter of the utility model embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1: the gas turbine blast furnace gas filter that the utility model embodiment provides comprises the valve body 1 being serially connected on blast furnace gas pipeline, be inclined at valve body Shang Lv road 2, filter cylinder 3, impeller 9, brush 4, blow-off pipe and scavenging conduit 7, filter cylinder 3 is fixed in filter road 2, brush 4 is arranged on filter cylinder 3 inside, the bristle of this brush 4 contacts with filter cylinder 3 inwalls, scavenging conduit 7 be arranged on filter road 2 one end and and filter cylinder 3 ends connections, impeller 9 is arranged in scavenging conduit 7 and is connected by rotating shaft with brush 4, the other end in filter road 2 is tightly connected by ring flange 5, blow-off pipe is through ring flange 5, blow-off pipe is provided with blowoff valve 6, blow down valve 8 is installed on scavenging conduit.
In needs filter rinsed, close air inlet and the gas outlet of gas turbine blast furnace gas filter, open blowoff valve 6 and blow down valve 8; On scavenging conduit 7, access 1.2MP nitrogen, owing to being provided with impeller 9 in scavenging conduit 7,9 rotations of nitrogen impeller, impeller 9 and brush 4 are coaxial rotation; Brush 4 will be rotated and swipe filter cylinder 3, the dust now sticking on filter cylinder 3 can be fast along with nitrogen is gone out from blow-off pipe together, whole process continues 1 minute, can be clean to cleaning filter, punching is swept after complete only need to shut blow down valve 8 and blowoff valve 6, and whole system just can work again.Wherein blow down valve 8 and blowoff valve 6 are all stop valve.
The inclination angle of filter road and valve body is 45 °, like this blast furnace gas by time, inclination angle Yue great Vietnamese side is filter residue and deslagging just, comparatively serious but the infringement in atmospheric Dui Lv road is crossed at inclination angle, 45 ° of position the bests of empirical tests.Brush is the wear-resisting brush of silica gel, because the wear-resisting brushing tool of silica gel has wear-resisting and flexibility, for filter cylinder, there is no destructiveness, and itself has resistance to acids and bases, has advantages of that the life-span is long.
Above-described is only preferred embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic is not done too much description at this.Should be understood that; for a person skilled in the art, not departing under the prerequisite of the utility model structure, can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
