Description
Technical field
Equipment is automatically adjusted the present invention is to provide the generating set boiler circulating water temperature of thermal power plant's field of cooling tower, specifically
It is a kind of roller shutter type cooling tower air intake self-checking device that ground, which is said,.
Background technology
1. with country《Energy law》Issuing and implementation and world energy sources worsening shortages, the energy conservation of enterprise seems more
Come more important, improve plant thermal efficiency, reach that energy-conservation is taped the latent power, reduced the purpose of maintenance cost, the problem of be current anxious to be resolved.
2. the operation level of condenser vacuum system directly affects the economy of Steam Turbine, safe operation.Analyze water temperature pair
Influence of the influence and condenser vacuum of condenser vacuum to unit economy, discloses cold in-water temperature and unit is imitated
The rule of rate influence.The influence to condenser vacuum is changed by quantitative calculating water temperature simultaneously, provided for cooling tower optimization operation
Quantitative analysis means and theoretical foundation, in the energy increasingly today in short supply, have reality to the economy for improving Steam Turbine
Meaning.
3. the antifreezing measures that existing cooling tower is used are mainly the method using artificial suspension deep bead.Cooling tower air inlet
Height, deep bead weight, volume is big, and suspension, excision workload are big, and manually operate dangerous, fragile.During suspension,
Artificial control suspension area makes cooling tower cause serious extension ice phenomenon not in time, causes packing in cooling tower, bracket to be dragged
Fall and part water drenching Structure Beam-column causes serious freeze-thaw dew muscle, cooling tower is controlled cooling water from normal safe operation and effectively
Temperature.
4. circulating water temperature directly affects the operation level of condenser vacuum system, power plant hyperbolic natural-draft cooling tower master
If manually demolition, installation water tower wind board adjusts circulating water temperature, because the Northeast's Temperature Difference Ratio is larger, especially daytime and night
The temperature difference differs more than 15 °C, and night dress deep bead is very unsafe, because water temperature adjustment makes circulating water temperature frequent not in time
Run in the case of higher or relatively low, this economy to vacuum and unit makes a big impact.
5. water tower maintenance is big, the deep bead now used needs winter all to hang up, and summer all removes, and dismounting is once broken
Damage very serious, usually also often remove, install during regulation circulating water temperature so that part deep bead causes to damage, it is so i.e. unrestrained
Substantial amounts of maintenance cost occurs again for expense material.
6. the demolition, installation of existing deep bead are entirely manually to complete, night due to illuminate it is insufficient in the case of tear open,
Fill deep bead and there is very big personal safety hidden danger, deficiency is especially illuminated in the winter time, the thicker action of the clothes worn is inconvenient, especially
It is on ground, ice is all knotted on beam column, dismounts deep bead special hazard.
