Description
Technical field
It the utility model is related to and block dirty strainer technical field, be specially that dirty filter is blocked in a kind of fired power generating unit cooling tower basin outlet
Net.
Background technology
It is all simple bar construction that existing fired power generating unit cooling tower tower basin outlet is usual, it is wider (at 10 lis to block dirty gap
It is more than rice), the filler fragment that comes off to cooling tower longtime running aging, around the blade that blows into the wind etc. do not have and block substantially
Effect is cut, these debris still will lean on water circulating pump entrance trash or straight panel strainer to intercept, and cleaning is all inevitable every time
To have part debris enter water circulating pump suction inlet so that get lodged in operation condenser water side heat exchange the mouth of pipe, increase water resistance,
Deteriorate generating set vacuum, reduce economics of power generation.
In addition, condenser water side heat exchange mouth of pipe blockage problem occurs, unit will be usually carried out to improve performance driving economy
Half side cleaning in operation, the half side measure of cutting off the water of condenser, which can all emit, great risk (being easy to cause operation chaser).
Utility model content
The purpose of this utility model is to provide a kind of outlet of fired power generating unit cooling tower basin to block dirty strainer, above-mentioned to solve
The problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical solution：A kind of fired power generating unit cooling tower basin outlet
Dirty strainer is blocked, including blocks dirty strainer body, it is described to block dirty strainer body and include filtering net plate, frame and band steel, the shape of the frame
Shape is arranged to step structure, and filtering net plate is provided with the frame, passes through band steel and bolt between the frame and filtering net plate
It is fixed.
Preferably, the frame is welded by channel steel, and channel steel is arranged to 80mm channel steels, and band steel is arranged to 50mm band steels.
Preferably, the ladder height of the frame is respectively 1300mm and 1800mm.
Preferably, the length of the frame is arranged to 7500mm, and the width of frame is arranged to 2500mm.
Preferably, the steel wire diameter of the filtering net plate is arranged to 2mm, and the mesh specification of filtering net plate is arranged to 15*15mm side
Hole.
Compared with prior art, the beneficial effects of the utility model are：The utility model is on source by sundries blocking, pole
It is big to reduce water circulating pump entrance trash or straight panel strainer cleaning work, effectively avoid debris from being entrained into condenser and block water side pipe
Beam, can guarantee that generating set long period safety and economic operation；Reduce water circulating pump inlet screen (straight panel structure) and clean number (day
Often operation cleans once for average 20 days, in tower basin plus can extend to 6 months after strainer and clean once), it is cold effectively to solve condenser
But water-pipe blockage problem, ensures condenser water damping difference ＜ 0.07Mpa (660MW units breathe out vapour condenser specification data), machine
Group can remain high economy operation；Eliminate the half side cleaning debris such as chaser risk, effective intercepting padding material fragment of condenser：Fill out
The debris such as material fragment generally all can effectively intercept debris in more than 20*20mm, opening of sieve 15*15mm；It can guarantee that long-term operation
Be convenient to clean debris：Water level in tower, can optionally be down to below two height by strainer ladder height 1300mm and 1800mm,
Filtering net surface debris can be cleaned；In addition the debris intercepted close to tower basin bottom can combine cooling tower dredging work and carry out, fortune
Effective flow area is not interfered between the departure date, can guarantee that unit does not occur to interrupt recirculated water event during operation；Avoid being fallen
Ice smashes：North of china in winter hyperbolic-type cooling tower ventilating opening edge easily freezes and comes off, and strainer depth width 2500mm, hides just
Cross the ice that vertically comes off and pound damage region soon.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, the utility model provides a kind of technical solution：Block dirt in a kind of fired power generating unit cooling tower basin outlet
Strainer, including dirty strainer body 5 is blocked, blocking dirty strainer body 5 includes filtering net plate 1, frame 2 and band steel 3, and the shape of frame 2 is set
For step structure, increase effective flow area, filtering net plate 1 is installed on frame 2, passes through band steel between frame 2 and filtering net plate 1
3 and bolt 4 fix, frame 2 is welded by channel steel, and channel steel is arranged to 80mm channel steels, and band steel 3 is arranged to 50mm band steels, frame 2
Ladder height be respectively 1300mm and 1800mm, optionally water level in tower can be down to below two height, you can with clean
Filtering net surface debris；In addition the debris intercepted close to tower basin bottom can combine cooling tower dredging work and carry out, will not during operation
