Abstract
The utility model discloses a W type hearth flame detection optical fiber lens. The W type hearth flame detection optical fiber lens comprises a corrugated pipe, an optical fiber pipe, a lens, and an isolation ring, wherein the optical fiber pipe comprises an inner pipe and an outer pipe; the corrugated pipe is installed at the back end of the inner pipe; the outer pipe wraps the outside of the inner pipe at the front end of the corrugated pipe; multiple ventilation grooves are formed in the wall of the outer pipe at the front end of the inner pipe; the lens is movably installed in the outer pipe at the front end of the inner pipe; the isolation ring is installed in the outer pipe at the back end of the lens. According to the utility model, as the optical fiber pipe is divided into an outer pipe and an inn pipe, and the ventilation grooves are additionally formed in the front end of the inner pipe, cooling air is enabled to be blown to the outer wall of the front end of the inner pipe directly between the two pipe walls while the cooling wind amount in both the corrugated pipe and the inner pipe is reduced, and the optical fiber in the front end of the inner pipe is cooled through a heat transfer effect; as the trumpet-shaped isolation ring is additionally arranged in the front end of the outer pipe, ash accumulation and coking phenomena of the front end of the optical fiber protected lens caused by positive pressure of the hearth can be prevented, and the cooling quality of the cooling wind for the lens and the optical fiber is ensured.
Description
Technical field
The utility model relates to furnace flame surveillance equipment in electric power or chemical industry, relates in particular to a kind of W type burner hearth fire inspection fiber lens.
Background technology
Fire inspection fiber lens is mainly used in coal-burning boiler burner hearth flame and detects; yet in use; often there will be fiery microscopy head and fire inspection optical fiber badly damaged phenomenon, cause the furnace flame monitoring system to exist flame to detect the problems such as inaccurate, that maintenance cost is high, maintenance workload is large.
By existing boiler furnace fire microscopy head and fire inspection optical fiber are followed the tracks of and analyzed, find to cause the reason of fiery microscopy head and fire inspection optical fiber well damage to have:
1, due to cooling air, to include dust more, easily cause dust stratification in fire inspection fiber optic protection bellows seriously to cause fire inspection optical fiber transfer capability to descend, affected normal flame monitoring, and the dust of long time integration washes away repeatedly to optical fiber, the ground away protection eyeglass of optical fiber front end, greatly reduce the service life of optical fiber, thereby increased Master Cost and maintenance workload;
2, because cooling air passes through from the outside of fiery microscopy head and fire inspection optical fiber; can't be cooled to the protection eyeglass of optical fiber front end; boiler for w-type combustion; this protection eyeglass front end more easily has coking and fouling phenomenon to produce; cause the cooling Quality Down of cooling air to fiery microscopy head and fire inspection optical fiber, cause the inaccurate even false alarm of flame monitoring.
The utility model content
The purpose of this utility model is to provide a kind of W type burner hearth fire inspection fiber lens that can prevent that burner hearth fire inspection fiber lens dust stratification from causing optical fiber to damage.
The W type burner hearth fire inspection fiber lens that the utility model provides, comprise bellows, optical fiber tube and camera lens, cage ring, described optical fiber tube comprises inner and outer tubes, described bellows is arranged on the inner tube rear end, and described outer tube is arranged on outside the inner tube of bellows front end, has some ventilation slots on the outer tube wall of described inner tube front end, described lens movable is installed in the outer tube of inner tube front end, and described cage ring is arranged in the outer tube of camera lens rear end.
Go out to blow for convenience the dust of inner tube inner accumulated, described inner tube comprises body and tube head, and described tube head is threaded connection and is arranged on the body front end, and described bellows is arranged on the body rear end, outer tube is wrapped in outside the body of bellows front end, and described ventilation slot is opened on the outer tube wall of described tube head.
Prevent from producing because of the burner hearth malleation dynamics of dust stratification and coking for strengthening the utility model, described cage ring adopts horn-type structure.
The utility model is by being divided into optical fiber tube the inner and outer pipes structure; and set up ventilation slot at the inner tube front end; can be in the situation that reduce cooling air quantity in bellows and inner tube; make cooling air directly from blowing between two tube walls to inner tube front end outer wall; pass through heat transfer effect; realize the cooling effect of inner tube front end inner fiber; can not affect its original cooling effect; and the trumpet type cage ring installed additional in the outer tube front end; the front end that can prevent the fiber optic protection eyeglass produces dust stratification and coking phenomenon generation because of the burner hearth malleation, guarantees the cooling quality of cooling air to camera lens and optical fiber.The utility model is simple in structure, easy to process, and it is convenient to install, and can strengthen the flame Detection accuracy of furnace flame monitoring system.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As can be seen from Figure 1, this W type of the utility model burner hearth fire inspection fiber lens, comprise bellows 1, optical fiber tube 2, camera lens 3 and cage ring 4, wherein optical fiber tube 2 comprises inner and outer tubes 23, inner tube comprises body 21 and tube head 22, bellows 1 is arranged on body 21 rear ends, tube head 22 is threaded connection and is arranged on body 21 front ends, outer tube 23 is wrapped in outside the body 21 of bellows 1 front end, have some ventilation slots 24 on the outer tube wall of tube head 22, camera lens 3 is dismountable to be movably installed in the outer tube 23 of inner tube front end, cage ring 4 is arranged in the outer tube 23 of camera lens 3 rear ends.
From Fig. 1, it can also be seen that, cage ring 4 of the present utility model adopts horn-type structure, and optical fiber is fixed in optical fiber tube 2 and camera lens 3 by some pins.
The process that existing fire inspection fiber lens is transformed is as follows:
(1) remove original fire inspection fiber lens.
(2) processing the utility model.
(3) all optical fiber metal bellows are carried out to deashing.
(4) bellows is connected to the rear end of the utility model optical fiber tube 2.
(5) static system debugging, arrange suitable signal gain.
(6) systematic parameter is adjusted.
