Abstract
The utility model provides a temperature reducing device for middle and small boilers. A plurality of straight pipes are fixed in a quincunx in a header of a superheater, an end head is divided into an upper and a lower layers by a spacer plate so that a circulating form is formed, and the middle of the circulating form is provided with a supporting plate which is penetrated through by the straight pipe, which plays positioning action. The temperature reducing device adopts a straight pipe-shaped surface type, cooling water is not easy to clog, and therefore, the temperature reducing device with convenient maintenance and low expenses can be replaced every eight to ten years; cooling water pressure is lower than steam pressure, and therefore, water can not flow into steam sides; temperature reducing effect can achieve about 50 DEG C to 80 DEG C, and the utility model with high safety is quite suitable for the middle and small boiler under 30T/H.
Description
The utility model relates to a kind of combustion apparatus, especially a kind of boiler desuperheater.
Existing boiler desuperheater, a kind of is fountain, simply is easy to do, and effect is also good, and shortcoming is to cause salt scale coagulation easily, forms to stop up and can not use.Another kind is generally to use at present, is bent into coiled pipe with φ 18 * 1.5 seamless pipes, the surface-type of interior water flowing, the logical vapour in surface, it is rational in infrastructure, and is easy to use, but tubule stops up easily, can't clear up, begin effectively, behind efficiency obviously reduced in three months, year must change half a year to one, change once, only the material money just needs 5000 yuan, does not manually calculate, and maintenance cost is big.
The purpose of this utility model provides a kind of straight tube shape surface-type, is difficult for stopping up, and long service life, maintenance cost is low, safe medium small boiler attemperator.
Technical solution adopted in the utility model is: be quincunx fixing some straight tubes 4 in superheater header 2, the termination is separated into upper and lower layer with dividing plate 7.Form circulation form, there is the piece support plate centre, allows straight tube pass, and plays the role of positioning.
This attemperator adopts straight tube shape surface-type, and cooling water is difficult for stopping up, and just need change once in 8～10 years, easy to maintenance, expense is low, cooling water pressure is lower than vapour pressure, can not cause water to flow into the vapour side, temperature lowering effect reaches about 50 ℃～80 ℃, and is safe, is highly suitable for the following medium small boiler of 30T/H.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A view of Fig. 1.
This attemperator is to adopt the straight tube of φ 16～φ 25 to make desuperheat pipe 4, in superheater header 2, be quincunx fixing some, the termination is separated into upper and lower layer with dividing plate 7, lower floor's water inlet, upper strata water outlet, there are circulating reflux chamber, centre to establish a support plate 5 outside the two ends fixed head 3, allow straight tube pass, play the role of positioning, not yielding.The bottom also is provided with steam trap 6.This attemperator can be made single, two groups of symmetries about also can establishing.Old furnace modification can about two groups, do not need to want again header.After cold water entered the desuperheat pipe from the bottom, steam was from desuperheat tube-surface process, and hot water is discharged from top, reached cooling desuperheat purpose.The temperature lowering effect of this attemperator can reach about 50 ℃～80 ℃.
Claims (1)
1, a kind of medium small boiler attemperator comprises some pipes, it is characterized in that: be quincunx fixing some straight tubes (4) in superheater header (2), the termination is separated into upper and lower layer with dividing plate (7).
