Abstract
The utility model relates to a kind of guiding spout cooling device, it comprises guiding spout (5), it is characterized in that being arranged with a cooling collar (4) outside described guiding spout (5), the side that described cooling collar (4) is positioned at guiding spout (5) afterbody is sealed by the first cooling collar cover plate (7) with holes, opposite side is sealed by the second cooling collar cover plate (8) not with holes, the long tube connector of pagoda head (3) for water inlet is inserted with in a hole of described first cooling collar cover plate (7), the pagoda head nipple (2) for water outlet is inserted with in another hole, pagoda head (1) is provided with in the outer end of described pagoda head nipple (2) and the long tube connector of pagoda head (3).The utility model in-site installation is reliably convenient, and structure is simple with making, reduces cost, also solves and breach higher temperature occasion to arrange a difficult problem of reliably blowing ash point.
Description
Technical field
The utility model relates to a kind of guiding spout cooling device, particularly relates to a kind of guiding spout device being applied in the band refrigerating module of shock wave soot-blowing system.
Background technology
Current guiding spout device generally all adopts carbon steel (as Q325, Applicable temperature scope 0 ~ 350 DEG C), stainless steel (as 304, Applicable temperature scope 500 ~ 800 DEG C) and heat resisting steel (as 2520, Applicable temperature scope 1000 ~ 1400 DEG C) etc.The high temperature section temperature of station boiler can reach 1300 DEG C, usually adopts heat resisting steel, and its cost is higher.In addition, higher temperature occasion (as incinerator, temperature can reach 1450 ~ 1800 DEG C) cannot arrange guiding spout device, causes this occasion very easily dust stratification.Thus reduce boiler output, boiler controller system utilization rate, boiler thermal output and service life, too increase coal consumption.Also can make flue blockage, smoke evacuation is not smooth, and exhaust gas temperature improves, and then local heating's face place cigarette speed is too high, and wearing and tearing increase, and makes rear portion heating surface more be subject to the impact of " acid dew ", accelerates corrosion, brings out the security incidents such as leakage, booster.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of guiding spout cooling device, structure is simple, can not only ensure reliably to arrange and blow grey point, and replaces high-grade steel effectively to reduce costs by low level steel.
The purpose of this utility model is achieved in that a kind of guiding spout cooling device, it comprises guiding spout, it is characterized in that being arranged with a cooling collar outside described guiding spout, the side that described cooling collar is positioned at guiding spout afterbody is sealed by the first cooling collar cover plate with holes, opposite side is sealed by the second cooling collar cover plate not with holes, the long tube connector of pagoda head for water inlet is inserted with in a hole of described first cooling collar cover plate, one end of the long tube connector of described pagoda head is positioned at cooling collar inside, the pagoda head nipple for water outlet is inserted with in another hole, pagoda head is provided with in the outer end of described pagoda head nipple and the long tube connector of pagoda head.
At the tube wall of described cooling collar, be positioned at place directly over the long tube connector of pagoda head have one for installing pressure-reducing valve to regulate and reducing the pressure-reducing valve installing hole of pressure near the first cooling collar cover plate side.
Compared with prior art, the beneficial effects of the utility model are:
The utility model in-site installation is reliably convenient, and structure is simple with making, reduces cost, also solves and breach higher temperature occasion to arrange a difficult problem of reliably blowing ash point.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein:
Pagoda head 1, pagoda head nipple 2, the long tube connector 3 of pagoda head, cooling collar 4, guiding spout 5, pressure-reducing valve installing hole 6, first cooling collar cover plate 7, second cooling collar cover plate 8.
Detailed description of the invention
See Fig. 1, the utility model relates to a kind of guiding spout cooling device, comprise pagoda head 1, pagoda head nipple 2, the long tube connector 3 of pagoda head, cooling collar 4, guiding spout 5, pressure-reducing valve installing hole 6, first cooling collar cover plate 7 and the second cooling collar cover plate 8, a cooling collar 4 is arranged with outside described guiding spout 5, the cooling collar 4 being positioned at guiding spout end seals with the second cooling collar cover plate 8, the other end the first cooling collar cover plate 7 seals, described cooling collar cover plate 7 offers two holes, one end of the long tube connector 3 of described pagoda head is inserted into cooling collar 4 inside by a hole of the first cooling collar cover plate 7, one end of described pagoda head nipple 3 is inserted in another hole of the first cooling collar cover plate 7, running water is introduced by the long tube connector 3 of pagoda head, pagoda head nipple 2 flows out, form fluid, thus reach the effect of cooled guide spout.The tube wall of cooling collar 4, place has a pressure-reducing valve installing hole 6 near the first cooling collar cover plate 7 side and directly over being positioned at the long tube connector 3 of pagoda head, a pressure-reducing valve can be set herein, effectively can regulate and reduce the high pressure because running water high-temperature evaporation formation steam produces.
Claims (2)
1. a guiding spout cooling device, it comprises guiding spout (5), it is characterized in that being arranged with a cooling collar (4) outside described guiding spout (5), the side that described cooling collar (4) is positioned at guiding spout (5) afterbody is sealed by the first cooling collar cover plate (7) with holes, opposite side is sealed by the second cooling collar cover plate (8) not with holes, the long tube connector of pagoda head (3) for water inlet is inserted with in a hole of described first cooling collar cover plate (7), one end of the long tube connector of described pagoda head (3) is positioned at cooling collar (4) inside, the pagoda head nipple (2) for water outlet is inserted with in another hole, pagoda head (1) is provided with in the outer end of described pagoda head nipple (2) and the long tube connector of pagoda head (3).
2. one guiding spout cooling device according to claim 1, it is characterized in that the tube wall in described cooling collar (4), be positioned at place directly over the long tube connector of pagoda head (3) have one for installing pressure-reducing valve to regulate and reducing the pressure-reducing valve installing hole (6) of pressure near the first cooling collar cover plate (7) side.
