Description
Technical field
The utility model relates to the coke removing appts in a kind of boiler fire inspection protection system.
Background technology
Boiler flame detection system is the important component part of FSSS (Boiler Furnace Safeguard Supervisory System) system, flame detection system is by the detection to flame characteristics and radiation spectrum, fire whether is had to monitor to burner hearth, in ignition of the boiler, underrun or when having unusual service condition, detect in burner hearth whether have fire in time, according to fire defector result, in FSSS, carry out interlock action, prevent stove chamber fire-extinguishing and stove implode accident, guarantee the safe operation of boiler.
But, during due to fired coal combustion, easily make fire inspection assembly front end engineering outer tube coking, especially in boiler combustion adjustment (as unit load down), change, the inconsistent of the fusion point of coal ash in reducing atmosphere and oxidizing atmosphere of primary and secondary air air quantity all easily cause coking, fire inspection is caused to detect inaccurate, the safe operation of grave danger boiler.Simultaneously because fire inspection bushing pipeline installation environment temperature is high, dust is many, space is little, fire inspection is caused to disclose burnt work difficulty large, frequently the damage (particularly fiery microscopy head group) of equipment is accelerated especially to the dismounting of fire inspection sensor line, fire inspection sleeve pipe, add cost of equipment maintenance.
Flame detecting device in the market does not all possess decoking function, limited use when probe cooling cold wind (pressure is about 0.6-0.7KPa) is particularly inclined to serious coal for coking to unit starting initial stage that acts on of slagging prevention, unit load down firing optimization, performing low-load running of machine set.Burnt workload is large, equipment maintenance cost is high to cause attendant to disclose.
Therefore, be necessary to design a kind of coke removing appts for coal fire inspection.
Utility model content
Technical problem to be solved in the utility model is to provide the coke removing appts in a kind of boiler fire inspection protection system, and the coke removing appts in this boiler fire inspection protection system is easy to implement, effectively can prevent the coking of fire inspection assembly, ensure that boiler fire inspection protection system is normally run.
The technical solution of utility model is as follows:
Coke removing appts in a kind of boiler fire inspection protection system, fire inspection mounting pipe (3) extend in the burner hearth of boiler through furnace wall outer wall (4), the fire inspection mounting pipe end be positioned at outside burner hearth is provided with installs pipe cap (2), fire inspection assembly (1) is inserted into be installed on pipe cap, the leading portion of fire inspection assembly extend in described burner hearth, and the rear end of fire inspection assembly is positioned at outside burner hearth;
One termination source of the gas of compressed air hose (6), the other end of compressed air hose extend into fire inspection mounting pipe from the tube wall of fire inspection mounting pipe; Compressed air hose is provided with air valve (5).
The diameter of compressed air hose is 20mm ~ 50mm.
As preferably, the diameter of compressed air hose is 30mm.
Described source of the gas is boiler maintenance compressed air mother pipe.
The positional distance that compressed air hose connects fire inspection mounting pipe installs pipe cap 35 ~ 65mm.
As preferably, the positional distance that compressed air hose connects fire inspection mounting pipe installs pipe cap 50mm.
Air valve is electrical ball valve or manual ball valve.
Beneficial effect:
Coke removing appts in boiler fire inspection protection system of the present utility model, adopts compressed air hose input compressed-air decoking.Making attendant not needing to enter under fire inspection sensor mounting location carries out dismounting and disclose the prerequisite of burnt work, being removed the coking at burner fire inspection position by compressed air.
Core of the present utility model is to make fire inspection mounting pipe and the fiery section noncoking examined between assembly by blowing compressed air, thus ensures whether correctly can observe burner hearth has fire.
Under the prerequisite of the ceteris paribus such as existing boiler structure, air force condition, coal-fired ature of coal, by less improvement expenses and retrofit work, make attendant when not needing to enter fire inspection sensor mounting location and carrying out dismounting and disclose burnt work, just can remove by compressed air the coking that burner fire examines position.Greatly safeguard and reduce workload, meanwhile, owing to no longer needing to carry out dismounting to fire inspection sleeve pipe and sensor, improve service life of equipment, annual every platform boiler at least can reduce tens thousand of first cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the coke removing appts in boiler fire inspection protection system.
Label declaration: 1-fire inspection assembly, 2-installs pipe cap, 3-fire inspection mounting pipe, 4-furnace wall outer wall, 5-air valve, 6-compressed air hose.
Detailed description of the invention
Below with reference to the drawings and specific embodiments, the utility model is described in further details:
Embodiment 1:
As Fig. 1, coke removing appts in a kind of boiler fire inspection protection system, fire inspection mounting pipe (3) extend in the burner hearth of boiler through furnace wall outer wall (4), the fire inspection mounting pipe end be positioned at outside burner hearth is provided with installs pipe cap (2), fire inspection assembly (1) is inserted into be installed on pipe cap, the leading portion of fire inspection assembly extend in described burner hearth, and the rear end of fire inspection assembly is positioned at outside burner hearth;
One termination source of the gas of compressed air hose (6), the other end of compressed air hose extend into fire inspection mounting pipe from the tube wall of fire inspection mounting pipe; Compressed air hose is provided with air valve (5).
The diameter of compressed air hose is 30mm.
Described source of the gas is boiler maintenance compressed air mother pipe.Compressed air hose welds manual ball valve;
The positional distance that compressed air hose connects fire inspection mounting pipe installs pipe cap 50mm.
The compressed-air actuated pressure of compressed air hose is 0.6-0.8Mpa.
Make regular check on compressed air line valve state, whether compressed air pressure is normal.During each decoking, the same time only carries out decoking to a point, after having worked, closes this road pipe valve.
In boiler fire inspection protection system running, when coal fire inspection installation front end is blocked up burnt, connect compressed air gas with flexible pipe former, open manual ball valve.When flame instruction is more than 95%, and be in stable, illustrate and remove coking, close manual ball valve.
