Abstract
The invention discloses a swinging burner flame detection probe, particularly relates to a flame detection probe swinging along with a burner, and belongs to the field of burning equipment. The flame detection probe is formed by connecting an outer sleeve pipe (1), a sliding flange, an outer sleeve pipe (8), a nut (9), an inner sleeve pipe (10), optical fibers (11) and a flame detector (12), wherein a corrugated pipe (1) is located in the middle of the outer sleeve pipe (8); the inner sleeve pipe (10) is fixed in the outer sleeve pipe (8) through the nut (9); the optical fibers (11) are arranged in the inner sleeve pipe (10) and used for being connected with the flame detector (12); the sliding flange is arranged outside the outer sleeve pipes in a sleeving mode. The swinging burner flame detection probe integrates the property characteristics of the corrugated pipe and the sliding flange, can swing along with the burner, effectively prevents the situation that as the outer sleeve pipes are broken due to rigid pulling when the flame detection probe swings, cooling air of the probe leaks out, and the probe is burned out, and guarantees normal operation of the flame detection probe and assemblies thereof, thereby more comprehensively detecting the burning condition of flame in real time and increasing mastering of the operation safety of a boiler. Meanwhile, the thoroughness of fuel combustion can be effectively observed, combustion equipment is improved, and resources are saved.
Description
Technical field
The present invention 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
This real goal of the invention 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 used in the present invention is, a kind of tilting burner flame detecting probe, is made up of 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).
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, tilting burner flame detecting probe of the present invention 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.
