Abstract
The utility model relates to a special-shaped pipeline filter for a steam turbine exhaust-steam condensing system, and belongs to the technical field of power generating equipment. According to the technical scheme, the special-shaped pipeline filter comprises a cylindrical shell, a cup-shaped stainless steel filter screen and a drainage pipe; the cylindrical shell is serially connected to an inlet pipeline of a circulating water pump of the steam turbine exhaust-steam condensing system through flanges at two ends of the cylindrical shell; the cup-shaped stainless steel filter screen is arranged in the cylindrical shell and fixedly connected with the liquid inlet end of the cylindrical shell through a flanging at an opening of the cylindrical shell; the drainage pipe is arranged in a hand hole in the side wall of the cylindrical shell and is in sealing connection with the side wall of the cylindrical shell; one end, arranged at the exterior of the cylindrical shell, of the drainage pipe is provided with a sealing cover plate, and one end, arranged at the interior of the cylindrical shell, of the drainage pipe is in abutting joint with a drainage port in the side wall of the cup-shaped stainless steel filter screen. The special-shaped pipeline filter can effectively prevent a steam condenser from being blocked, shortens the maintenance time of the condenser, and ensures normal operation of a steam turbine, thus improving the power generation efficiency of power plants. Moreover, the special-shaped pipeline filter further has the advantages of simple structure, low cost, convenience in field use and the like.
Description
Technical field
The utility model relates to a kind of filter used in the circulating water cooling system of gas to generate electricity unit, belongs to the generating equipment technical field.
Background technology
The open type of cooling of the general employing of the circulating water cooling system of 60 MW gas to generate electricity units, plant condenser is easy to be blocked by the impurity in environment and the filler that comes off, the cooling effect of cooling system is worsened, condenser vacuum reduces, and then affect generating efficiency and the generated energy of generating set, and the frequent obstruction of condenser has also increased the maintenance clearance time (clear up condenser at every turn and need 3 day time) of condenser greatly, shorten the running time of steam turbine, thereby had a strong impact on the economic benefit of power plant.Therefore, how effectively to prevent that the condenser obstruction from just becoming the problem that the relevant technologies personnel face.
The utility model content
The purpose of this utility model is the drawback for prior art, and a kind of special-shaped piping filter for the exhaust steam in steam turbine condenser system is provided, and thoroughly solves the problem that condenser easily blocks.
Problem described in the utility model realizes with following technical proposals:
A kind of special-shaped piping filter for the exhaust steam in steam turbine condenser system, formation comprises cylindrical case, cup-shaped stainless steel filtering net and blow-off pipe, described cylindrical case is serially connected in the inlet duct of exhaust steam in steam turbine condenser system water circulating pump by the flange at its two ends, described cup-shaped stainless steel filtering net is positioned at cylindrical case affixed by flange and the cylindrical case liquid feeding end of its opening part, described blow-off pipe is positioned at the hand hole on the cylindrical case sidewall and is tightly connected with the cylindrical case sidewall, its end that is positioned at the cylindrical case outside is provided with seal cover board, an end that is positioned at cylindrical case inside docks with the sewage draining exit on cup-shaped stainless steel filtering net sidewall.
The above-mentioned special-shaped piping filter for the exhaust steam in steam turbine condenser system, the bottom of described cup-shaped stainless steel filtering net is connected with the sidewall of cylindrical case by reinforced liner.
The above-mentioned special-shaped piping filter for the exhaust steam in steam turbine condenser system, the mesh diameter of described cup-shaped stainless steel filtering net is 8mm.
The utility model utilizes the foreign material in cup-shaped stainless steel filtering net filtering exhaust steam in steam turbine condenser system circulation line, realize the quick cleaning of filter residue by blow-off pipe, effectively prevented the condenser obstruction, greatly shortened the repair time of condenser, guaranteed the normal operation of steam turbine, thereby improved the generating efficiency of power plant, reduced the operating cost of steam turbine.In addition, the utility model also have simple in structure, with low cost, be convenient to the advantage such as on-the-spot use.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the top view of Fig. 1.
In figure, each list of reference numerals is: 1, cylindrical case, 2, cup-shaped stainless steel filtering net, 3, blow-off pipe, 4, reinforced liner, 5, seal cover board.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model comprises cylindrical case 1, cup-shaped stainless steel filtering net 2, blow-off pipe 3, reinforced liner 4 and seal cover board 5.Cup-shaped stainless steel filtering net 2 adopts the stainless (steel) wire that aperture is φ 8 to make, and its openend is fixedly connected with the inlet flange of cylindrical case 1.The reinforcing bar of reinforced liner 4 use φ 10 is made, both can cup-shaped stainless steel filtering net 2 is reliably fixing, can guarantee again the flow area of cylindrical case 1.Be provided with hand hole on the sidewall of cylindrical case 1, the blow-off pipe 3 of cup-shaped stainless steel filtering net 2 passes and is tightly connected with the sidewall of cylindrical case 1 from hand hole.
During the operation of exhaust steam in steam turbine condenser system, foreign material in recirculated water are stopped by cup-shaped stainless steel filtering net 2 and in the interior gathering of cup-shaped stainless steel filtering net 2, when the foreign material aggregate amount is more, the attendant opens the seal cover board 5 of blow-off pipe 3 outer ends, by the foreign material in 3 pairs of cup-shaped stainless steel filtering nets 2 of blow-off pipe, clears up fast.
The utility model has solved problem and small investment, simple in structure, easy to operate that plant condenser easily blocks well, this device implementation result is obvious, can adjust at any time its size and profile according to structure and the space for maintenance of on-the-spot pipeline, therefore be applicable to various pipes.
