Abstract
The utility model relates to a single-drum type steam double-efficiency lithium bromide-absorption cooling water machine unit. An evaporator (1), an absorber (2), a low pressure generator (3), a condenser (4) and a high pressure generator (5) are all arranged in a drum body (6), and the upper part and the lower part of the drum body are separated by a baffle plate (7) below which a heat baffle plate (9) with a miniature hole (8) is arranged. Due to the adoption of the single-drum type structure, compared with the prior art, the utility model has the characteristics of compact structure, small size, small heat energy loss of the high pressure generator, improvement of force applied to a casing of the high pressure generator, requirement lowering for intensity design, high air tightness of the machine unit (especially the high pressure generator), etc.
Description
The utility model relates to a kind of lithium bromide absorption cold water unit, particularly a kind of single cylinder type steam double-effect lithium bromide absorption type handpiece Water Chilling Units.
Existing steam double-effect lithium bromide absorption type handpiece Water Chilling Units all adopts three cylindrical structures, i.e. evaporimeter, cylindrical shell of absorber, cylindrical shell of low pressure generator and condenser, cylindrical shell of high pressure generator.The weak point of this structure is:
1, set structure is loose, volume is bigger;
2, the high pressure generator heat-energy losses is big, generatine set heat efficiency is low: high pressure generator is owing to directly place atmosphere, and its shell and ambient atmosphere are carried out heat exchange and lost heat energy, and generatine set heat efficiency is low:
3, the stressed complexity of high pressure generator shell, requirement of strength design height: because the high pressure generator temperature is higher, variations in temperature is bigger in unit operation, thermal stress is also bigger, inside and outside differential pressure is the pressure reduction between high pressure generator and the atmosphere, so shell is stressed very complicated, the requirement of strength design height;
4, the poor air-tightness of unit (particularly high pressure generator): because the unit of three cylindrical structures is with the ambient atmosphere contact area is big, solder joint is many, so the source of trouble of unit is many, the air-tightness of unit can not get guarantee.
The purpose of this utility model is to overcome the above weak point of prior art and a kind of single cylinder type steam double-effect lithium bromide absorption type handpiece Water Chilling Units is provided.
The technical solution of the utility model is: single cylinder type steam double-effect lithium bromide absorption type handpiece Water Chilling Units adopts the single cylinder type structure, and promptly evaporimeter, absorber, low pressure generator, condenser and high pressure generator place in the cylindrical shell.
The further technical scheme of the utility model is: evaporimeter places the right, cylindrical shell bottom, absorber places the left side, cylindrical shell bottom, high pressure generator and low pressure generator are placed side by side cylindrical shell top, one dividing plate is arranged between the cylindrical shell upper and lower part, one thermal insulation board that has a micropore is arranged below the dividing plate in addition, condenser places the top of cylindrical shell top low pressure generator, and low pressure generator solution overfall is arranged on the low pressure generator, and the side on cylindrical shell top has the low pressure generator taphole to take over.
The utility model is compared with existing three cylindrical structures owing to adopt the single cylinder type structure, has following advantage:
1, set structure compactness, volume is little;
2, the high pressure generator heat-energy losses is little, generatine set heat efficiency height: because high pressure generator places in the cylindrical shell top, make flow through gap between high pressure generator and the dividing plate of the low pressure generator concentrated solution that flows out from the low pressure generator overfall, fully and the high pressure generator housing contacts, and then through low pressure generator concentrated solution discharge connection outflow cylindrical shell, be that high pressure generator is immersed in the low pressure generator concentrated solution, carry out thermal conversion with the low pressure generator concentrated solution, make concentrated solution further obtain evaporation and concentration, simultaneously, because the environment temperature when the low pressure generator concentrated solution is more external than high pressure generator is much higher, so more stoped the high pressure generator heat outwards to scatter and disappear, improved the evaporation effect of high pressure generator, thoroughly avoided high pressure generator heat radiation and the heat loss that causes of cross-ventilation to external world, the thermal efficiency of unit significantly improves;
3, the tripping generator shell is stressed improves, requirement of strength design reduces: because high pressure generator places in the cylindrical shell fully, high pressure generator shell pressure is the pressure reduction between high pressure generator and the low pressure generator, greatly reduce so the high pressure generator shell is stressed, and upper and lower part two cavity volume pressure reduction are lower than the inside and outside differential pressure of three cylindrical structures in the cylindrical shell, dividing plate and evaporimeter, that the absorber shell is compared pressure is less, so the requirement of strength design of high pressure generator and dividing plate is all not high;
4, the air-tightness of unit (particularly high pressure generator) is good: after the utility model adopts the single cylinder type structure, reduced the contact area of unit and ambient atmosphere, the also corresponding minimizing of welding portion, high pressure generator places in the cylindrical shell, the dividing plate pressure is also less, so both made high pressure generator and dividing plate have little leakage, and also can not make unit sneak into on-condensible gas and reduce unit performance.
Below in conjunction with drawings and Examples detailed structure of the present utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
As shown in drawings: single cylinder type steam double-effect lithium bromide absorption type handpiece Water Chilling Units adopts the single cylinder type structure, it is evaporimeter (1), absorber (2), low pressure generator (3), condenser (4) and high pressure generator (5) all place in the cylindrical shell (6), evaporimeter places the right, cylindrical shell bottom, absorber places the left side, cylindrical shell bottom, high pressure generator and low pressure generator are placed side by side cylindrical shell top, on the cylindrical shell, separate with a dividing plate (7) between the bottom, also has a thermal insulation board (9) that has micropore (8) below the dividing plate, condenser places the top of cylindrical shell top low pressure generator, low pressure generator concentrated solution overfall (10) is arranged on the low pressure generator, and there is low pressure generator taphole pipe (11) side on cylindrical shell top.
