Description
Technical field
This utility model is related to a kind of air preheater fire-fighting system, and in particular to a kind of sky with portable drenching sprayer is pre-
Device fire-fighting system.
Background technology
Air preheater is the important auxiliary equipment of station boiler, and Main Function is to reclaim to leave boiler soda pop endotherm section
Flue gas heat, heats combustion air, reduces exhaust gas temperature, improves boiler thermal output.Air preheater realizes the function group of gas-gas heat exchange
Part is rotor, and rotor is made up of multiple mode sector storehouses.Thousands of corrugated platings, i.e. carbon is included in each mode sector storehouse
Steel thin slice.When these corrugated platings go to air preheater flue gas storehouse, (360 DEG C～370 DEG C of flue-gas temperature) absorbs heat, goes to air bin
Heat is discharged when (20 DEG C～30 DEG C of First air, secondary wind temperature), realize the heat exchange between flue gas and air.
, in initial start stage or low load stage, the oil gun that can come into operation is combustion-supporting for station boiler, the feelings for occurring oily coal multifuel combustion in burner hearth
Condition.Now in stove, burning condition is poor, and a large amount of coal dusts and oil droplet are burnt completely to be just less easily entrained by and enter back-end ductwork,
And eventually arrive at air preheater.The thickly dotted corrugated plating of arranging in air preheater sector storehouse, the gap very little between plate, because
This larger oil droplet, coal dust are difficult to through fan-shaped storehouse, just in corrugated cardboard sheet top adhesion and aggregation, are gradually formed with certain area
Fuel dirt.The ignition of the boiler initial stage, in flue gas contain substantial amounts of high temperature soot particle, these soot particles as kindling material, in a steady stream not
Disconnected strikes on fuel dirt, and will ignite dirt under certain condition, causes air preheater to catch fire.
Existing air preheater fire plant, mostly using the fixed sprinkler pipe with multiple shower nozzles, once the condition of a fire is found,
Ignition point position is not differentiated between, but big flow Water spray is carried out to all fan-shaped storehouses in whole flue gas storehouse.The fire-fighting system is by fire
Disaster area domain and non-conflagration area are equally sprayed water, and also cold water spray have been arrived on the corrugated plating of normal work, so while fire extinguishing
On the one hand the significant wastage of water resource is caused, on the other hand, the carbon steel coupon corrugated plating of high temperature is subject to cold water shock suddenly, easily
Cause material damage, reduction of service life.

This utility model has the advantages that：
Air preheater fire-fighting system with portable drenching sprayer described in the utility model in specific works, by temperature
In degree sensor array real-time detection air preheater in flue gas storehouse each test point of rotor surface temperature information, and by each test point
Temperature information is forwarded in on-site control, according to the temperature information of each test point, on-site control judges whether each test point is sent out
Raw Ignition Phenomena, when arbitrary test point occurs Ignition Phenomena, on-site control is passed according to the temperature for detecting Ignition Phenomena
The position control movable type drenching sprayer of sensor moves to fire location, and on-site control control electrically operated valve is opened, fire water
Fire water Jing electrically operated valves and portable drenching sprayer in feed system is ejected into fire location, puts out fire, so as to accurate
Complete the sprinkling fire to ignition point, simple structure is easy to operate, and practicality is extremely strong.
