Abstract
The utility model relates to a J-shaped high pressure boiler for a lithium bromide cold/warm water device, which comprises a casing body, a hearth, a rear smoke box, a smoke heat exchanger, a vapor-liquid separation device and a steam groove. The hearth is a round tube. The surface of the inner wall of the hearth is welded with radiating fins capable of strengthening radiation heat transfer. The rear smoke box is a wet back type structure. The smoke heat exchanger is a shell and tube type heat exchanger vertically arranged on the rear smoke box. The vapor-liquid separation device is composed of more than two stainless steel nets. The utility model is designed in a vertical J shape, and adopts the wet back type structure and radiating fins. Thus the utility model lightens the machine weight, increases the radiation heat transfer area, and enhances the energy utilization.
Description
The utility model relates to air-conditioning equipment, the direct-fired J type high pressure generator on particularly a kind of lithium bromide cooling-water machine.
High pressure generator on the lithium bromide absorption cooling and warming water machine of producing all is the straight flue of plain edition at present, and adopts dried back of the body formula structure at smoke box position, back.Owing to be straight flue, so can't avoid the thermal stress that causes by combustion pulsation.Therefore, this dried back of the body formula structure will cause problems such as the thermal efficiency is low, volume big, poor reliability because of using refractory material.
The purpose of this utility model provides a kind of lithium bromide cold and hot water machine J type high pressure generator, and it is designed to alphabetical J type, has alleviated machine weight, has increased the radiation heat transfer area.
A kind of lithium bromide cold and hot water machine described in the utility model comprises shell body with J type high pressure generator, flue, and back smoke box, flue gas heat exchanger, and vapor-liquid separating device, it also is included in the vapour groove of getting rid of steam to prevent to produce vapour locking that install the flue top; Described flue is a pipe, is welded with the radiation side of body sheet that can strengthen radiation heat transfer on the round tube inner wall surface; Described back smoke box is the wetting back-type structure, promptly forms the path of flow of solution between back smoke box and shell body, saves refractory material with the connecting portion of flue gas heat exchanger and directly is connected at flue; Described flue gas heat exchanger is a tubular heat exchanger, vertical being installed on the smoke box of back; Described vapor-liquid separating device is made up of stainless steel cloth more than two layers, and is clamped by strap, and vapor-liquid separating device is installed in a side of flue gas heat exchanger, is supported by support.
The utility model is designed to vertical J type, adopts wetting back-type structure and radiation side of body sheet, has alleviated machine weight thus, has increased the radiation heat transfer area, has improved energy utilization rate.The utility model is taken measures owing to absorption being breathed the thermal stress that is caused that expands, and has improved direct-fired high pressure generator operational reliability.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the structural representation of a kind of lithium bromide cold and hot water machine with J type high pressure generator.
Fig. 2 is the flue viewgraph of cross-section in the above-mentioned J type high pressure generator.
Referring to Fig. 1 and Fig. 2, a kind of lithium bromide cold and hot water machine comprises shell body with J type high pressure generator, flue 1, back smoke box 2, flue gas heat exchanger 3, and vapor-liquid separating device 4.
It also is included in the vapour groove 5 that install flue 1 top.Since in the high pressure generator solution some be bottom horizontal flow sheet, be easy to generate vapour locking and cause the circulation failure, vapour groove 5 is installed, to get rid of steam.
Shell body is a pipe 6, and each parts is coated.
Flue 1 is a pipe, is welded with radiation side of body sheet 13 on the round tube inner wall surface, to strengthen radiation heat transfer.It can improve the radiation heat transfer amount, has reduced furnace volume simultaneously.The front end of flue 1 has the mouth 7 of a flare shape, is convenient to be connected with burner.The rear end of flue 1 is provided with rearview mirror 8, is convenient to spy on the combustion case in the burner hearth.
Back smoke box 2 is the wetting back-type structure, promptly between back smoke box 2 and shell body 6, form the path of flow of solution, save refractory material with the connecting portion of flue gas heat exchanger 3 and directly be connected at flue 1, butt welding is all adopted in all welding at this position, alleviated the weight of high pressure generator thus, increase the radiation heat transfer area of high pressure generator, improved energy utilization rate.
Flue gas heat exchanger 3 is tubular heat exchangers, walks flue gas in its pipe, and pipe is outer to be solution, vertical being installed on the smoke box 2 of back.The upper end of flue gas heat exchanger 3 is exhanst gas outlets 12.
Vapor-liquid separating device 4 is made up of the multilayer stainless steel cloth, and is clamped by strap.Vapor-liquid separating device 4 is installed in a side of flue gas heat exchanger 3, is supported by support 9.The top of vapor-liquid separating device 4 is provided with steam (vapor) outlet 10, and the bottom of vapor-liquid separating device 4 is provided with visor 11.
The utility model adopts wetting back-type structure and radiation side of body sheet, can improve the safety operation level of complete machine, therefore can not cause owing to the refractory material be full of cracks comes off the back smoke box is burnt out.
