Abstract
The utility model discloses a kind of tilting burner flame detecting probe, can carry out the flame-detecting probe that swings exactly specifically along with burner.It is by outer tube (1), slip flange, outer tube (8), nut (9), inner sleeve (10), optical fiber (11) flame detector (12) connects to form, wherein bellows (1) is positioned at outer tube (8) centre position, inner sleeve (10) is fixed in outer tube (8) by nut (9), optical fiber (11) is placed in inner sleeve (10), for connecting flame detector (12), slip flange is enclosed within outside outer tube, on the basis that original flame detecting probe designs, merge the performance characteristics of bellows and slip flange, when effectively preventing flame detecting probe to swing, outer tube causes because rigidity pulls and breaks, thus cause probe cooling air to leak, the generation of probe burn observations.The innovation of this flame detecting probe is the method by improving flame detecting probe outer sleeve structure (increasing by one section of bellows and slip flange apparatus), ensure the normal operation of flame detecting probe and assembly thereof, thus combustion position flame being detected that can be more comprehensively real-time, enhance the control to boiler operatiopn security, also effectively can observe the adequacy of fuel combustion simultaneously, thus improve combustion apparatus, economize on resources.
Description
Technical field
The utility model relates to a kind of tilting burner flame detecting probe.
Background technology
Safety first, precaution crucial has become the basic guideline of safety of China production, and all enterprises all should adamantinely carry out.Therefore the novel boiler safety device of constantly innovation research and development remains a very important topic.As the first line of defence detecting boiler whether safe and stable operation, traditional flame detector probe is in the process swung with burner nozzle, its flame detecting probe pipe may be pullled power because being subject to larger rigidity and break, thus cause cooling air to leak, probe burns, and has had a strong impact on the safety of boiler combustion system.In order to avoid the generation of this situation, reduce the economic loss of enterprise, the structural shape improving flame detecting probe seems very important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of tilting burner flame detecting probe, the flame detecting probe of height swing can be carried out exactly specifically along with burner nozzle, probe swings with burner nozzle, monitor the flame combustion situation of related burner real-time and accurately, strengthen the ability to the monitoring of boiler operatiopn stability with this.
To achieve these goals, the technical solution adopted in the utility model is, it is on the basis of existing conventional flame detecting probe structure, then on its outer tube, increase bellows (1) and slip flange, as shown in Figure 1.
further, outer tube (8) is divided into two, front-end and back-end part by bellows (1), and connecting front-end and back-end, front end is placed in boiler internal, and rear end is placed in boiler exterior, like this can when flame detecting probe swings with burner nozzle, ensure certain flexibility and stroke, simultaneously also can Free Transform, prevent rigidity conflict, bellows (1), outer tube (8) adopt stainless steel steel matter, and label can be selected to be the stainless steel of 304 or 316.
further, slip flange is added in outer tube (8) rear end and fixes, the rear end of existing conventional outer tube is directly fixed by welding on boiler casing, produces rigidity so possibly pull problem when popping one's head in and swinging.And when adopting slip flange to fix, outer tube can carry out relative motion relative to furnace wall, thus the range difference produced when effectively swinging with burner nozzle flame detecting probe carries out second time compensation.
further, slip flange, comprise straight tube (2), inner shield ring (4), seal (5), Wai Dangquan (6), fastening nut (7), wherein straight tube (2) bonding pad letter (3), inner shield ring (4) is placed in stuffing-box (3) bottom, seal (5) is placed on inner shield ring (4), and Wai Dangquan (6) is placed on seal (5), and fastening nut (7) is threaded connection stuffing-box (3).
further, described straight tube (2), inner shield ring (4), Wai Dangquan (6), fastening nut (7), adopt carbon steel material, seal (5), adopts packing_seal, can select asbestos packing.
the invention has the beneficial effects as follows: increase bellows in outer tube (8) front end; ensure certain flexibility and stroke; prevent rigidity conflict; increase in outer tube (8) rear end the relative motion compensation that a slip flange realizes flame detecting probe pipe and furnace wall simultaneously, guarantee that flame detecting probe can swing safely with burner nozzle.

Detailed description of the invention
refer to shown in accompanying drawing, the utility model tilting burner flame detecting probe is further described.
as shown in Figure 1, tilting burner flame detecting probe, by bellows (1), straight tube (2), stuffing-box (3), inner shield ring (4), seal (5), outer back-up ring (6), fastening nut (7), outer tube (8), nut (9), inner sleeve (10), optical fiber (11), fire inspection processor (12) composition, wherein bellows (1) is positioned at outer tube (8) centre position, inner sleeve (10) is fixed in outer tube (8) by nut (9), optical fiber (11) is placed in inner sleeve (10), for connecting flame detector (12), slip flange is enclosed within outside outer tube.
outer tube (8) is divided into two, front-end and back-end part by bellows (1), and connect front-end and back-end, front end is placed in boiler internal, rear end is placed in boiler exterior, when flame detecting probe swings with burner nozzle, can ensure certain flexibility and stroke like this, simultaneously also can Free Transform, prevent rigidity conflict, bellows (1), outer tube (8) adopt stainless steel steel matter, and label can be selected to be the stainless steel of 304 or 316.
when burner nozzle drives flame detecting probe to arrive full swing amplitude, compensation only by metal bellows (1) is not much of that, also need in addition by slip flange make fire inspection outer tube (8) can and furnace wall between realize relative motion, effectively prevent because probe swing inclination angle is excessive and cause flame detecting probe tracheal rupture, probe cooling air is caused to leak, the generation of probe burn observations.Slip flange is added in outer tube (8) rear end fix, the rear end of existing conventional outer tube is directly fixed by welding on boiler casing, produces rigidity so possibly pull problem when popping one's head in and swinging.And when adopting slip flange to fix, outer tube can carry out relative motion relative to furnace wall, thus the range difference produced when effectively swinging with burner nozzle flame detecting probe carries out second time compensation.
described slip flange, comprise straight tube (2), inner shield ring (4), seal (5), Wai Dangquan (6), fastening nut (7), wherein straight tube (2) bonding pad letter (3), inner shield ring (4) is placed in stuffing-box (3) bottom, seal (5) is placed on inner shield ring (4), outward when circle (6) is placed on seal (5), fastening nut (7) is threaded connection stuffing-box (3), guarantees the sealing before outer tube (8) and slip flange.
described straight tube (2), inner shield ring (4), Wai Dangquan (6), fastening nut (7), adopt carbon steel material, seal (5), adopts packing_seal, can select asbestos packing.
