Abstract
The improved high pressure generator includes a steam chamber containing high pressure generating unit inside hearth, which consists of two halved hearths with heat insulating layer on its wall and heat exchange pipe group of wound seamless ribbed steel pipe. Without crack and leakage, the present invention has high energy utilization and long service life.
Description
The present invention relates to the high pressure generator technical field of lithium bromide air-conditioning, particularly a kind of modified high pressure generator.
What existing high pressure generator adopted is the oblique water pipe sandwich type structure of vertical heater tube, and the heat-exchange tube of this structure becomes oblique dense arrangement in burner hearth, two ends and hearth wall welding; An interlayer between hearth wall and shell, lithium-bromide solution is full of wherein, considers the solution leakage problem, and the shell of this structure is the monoblock type Welding Structure.In use, this high pressure generator exists following shortcoming: (1) is because the high-temperature flue gas stream variations in temperature that heat-exchange tube bears is very big, under the uneven situation of thermal expansion, easily produce thermal stress, cause the weld of heat-exchange tube and burner hearth wallboard that the crack leakage takes place; (2) the heat exchange group of this arranged askew formation also is unfavorable for leak detection and removes cigarette ash; (3) because this heat-exchange tube surface be a light pipe, too fast high-temperature flue gas flow also less than with heat-exchange tube in the solution sufficient heat exchange just discharge outside the burner hearth, cause energy waste; (4) because shell is the monoblock type Welding Structure,, could overhaul if inner generation problem need be destroyed shell during maintenance, and drain lithium-bromide solution, cumbersome.
The purpose of this invention is to provide a kind of heat-exchange tube and burner hearth does not have welding, the heat exchanger effectiveness height, and easy-to-maintain modified high pressure generator is to solve the deficiencies in the prior art part.
For achieving the above object, the technical solution adopted in the present invention is: the modified high pressure generator, comprise that the high pressure that contains steam chamber wraps, bag takes place and is placed in the burner hearth in described high pressure, the intermediate solution outlet is arranged on it, in health hot water wraps into and out of the described high pressure of pipe insertion, the refrigerant vapor outlet is arranged on the described steam chamber, it is characterized in that described burner hearth is combined by two half of burner hearths, and on hearth wall, heat-insulation layer is arranged; In described burner hearth, also has a heat exchange nest of tubes, described heat exchange nest of tubes is to adopt gapless stainless steel tube to turn to flat drum shape circle structure, stainless steel pipe surface in flat drum shape structure bottom is a light pipe, the stainless steel pipe surface on middle part and top all has fin, the fin quantity on its top is obviously more than the fin quantity at middle part, bag takes place with described high pressure and links to each other in the upper end mouth of pipe of described heat exchange nest of tubes, and the lower end mouth of pipe stretches out outside the burner hearth.
Owing to adopted as above design, the present invention has following advantage: (1) since heat-exchange tube mine massively and used gapless stainless steel tube to turn to flat drum shape circle structure, cancelled the welding of former heat-exchange tube and hearth wall, thereby, having stopped influences heat-exchange tube and the hearth wall weld crack leakage problem that occurs because of thermal stress, also corrosion-resistant than the red copper heat-exchange tube, prolonged service life; (2) the heat exchange nest of tubes of this structure helps deashing and leak detection; (3) flat drum shape circle structure heat exchange nest of tubes in, top is provided with fin, increased endotherm area, can make high-temperature flue gas stream fully with the heat exchange nest of tubes in solution carry out heat exchange, improved energy utilization rate; (4) because burner hearth adopts two halves to combine, more help maintenance.
Fig. 1 is a structural representation of the present invention.
Further describe the present invention below in conjunction with accompanying drawing.
Modified high pressure generator as shown in Figure 1, burner hearth 1 adopts bolt 4 to combine the heat-insulation layer 5 that has high-temperature resistant thermal insulating material to make on the hearth wall of burner hearth 1 by two half of burner hearths 2,3.Bag 7 and heat exchange nest of tubes 8 take place in the high pressure that is mounted with band steam chamber 6 in the burner hearth 1, and intermediate solution outlet 9 is arranged on bag 7 takes place high pressure, and health hot water inserts high pressure into and out of pipe 10 and takes place in the bag 7 refrigerant vapor mouth 11 is arranged on the steam chamber 6.
Heat exchange nest of tubes 8 is to adopt gapless stainless steel tube to turn to the flat drum shape coil structures, stainless steel pipe surface in flat drum shape structure bottom 12 is a light pipe, the stainless steel pipe surface on middle part 13 and top 14 all has fin 15, fin 15 quantity on its top 14 be middle part 6 fin 15 quantity 2-3 doubly, bag 7 takes place with high pressure and links to each other in the upper end mouth of pipe of this heat exchange nest of tubes 8, and the lower end mouth of pipe stretches out outside the burner hearth 1.
