Description
Technical field
The utility model relates to vaporizer technology field, especially a kind of spray-type evaporator.
Background technique
Spray-type evaporator, also referred to as downward film evaporator, are different from full-liquid type lower part feed flow, and spray-type evaporator is generally adopted
Refrigerant liquid is sprayed onto heat exchanger tube downwards from evaporator shell internal upper part with built-in knockout, refrigerant liquid and pipe
Interior refrigerating medium constantly exchanges heat, and manages outer liquid refrigerant and constantly flashes to gaseous refrigerant, dispenser is again constantly by liquid
Refrigerant adds on heat exchanger tube, so that heat exchange pipe surface is had a membranaceous layer always, uses the refrigeration system system of spray-type evaporator
Cryogen charging amount greatly reduces, and 30% refrigerant is at least saved than full-liquid type system, and Energy Efficiency Ratio is suitable with full-liquid type unit.Such as
Fruit will guarantee the heat transfer efficiency of spray-type evaporator, one of them technical detail for having to pay attention to is sought to built in rational design
Formula dispenser, guarantee liquid separation be the key that uniformly play evaporator as a whole efficiency, but often dispenser due to designing, processing work
The problems such as skill and the levelness of units' installation, causes its liquid separation to be difficult to accomplish visibly homogeneous, and even if these problems all solve
, since liquid refrigerant can generate a part of flash gas by throttle mechanism, actually enter the system inside dispenser
Cryogen is gas-liquid mixture phase, and the distribution under gas-liquid mixture phase is just more difficult to accomplish uniformly, is especially fluctuated in unit load
Its distribution effects is more undesirable when caused plus-minus load process or operating condition change, so as to cause entire evaporator
The big heavy discount of operational efficiency.How to allow dispenser can liquid separation more evenly, how to improve the heat exchange efficiency of spray-type evaporator,
It has become when previous technical problem.
It is improved in the industry, such as a kind of disclosed spray-type evaporator of Chinese patent, application No. is
201510504150.0, it is described: being additionally provided with liquid barrier between the falling film evaporation area and the full liquid evaporating area, it is described
Liquid barrier be one piece of groove-shaped supporting board, between surrounding and the heat exchanger shell and the first tube sheet, the second tube sheet there are
Gap.Liquid barrier (can be seen that it in inverted trapezoidal groove shape from the patent schematic diagram) is provided in heat exchanger, by falling film evaporation area
It is separated with full liquid evaporating area, reduces disturbance of the liquid of top falling film evaporation area drippage to full liquid evaporating area evaporating state, shadow
The heat exchange of the evaporating area bottom Man Ye is rung, to further increase the heat exchange efficiency of full liquid evaporating area.
Above-mentioned technical proposal has problems in that: liquid barrier will certainly fill with excessive in the case where dispenser constantly sprays
Out, the drop that the liquid flowing ratio of spilling is dripped from heat exchanger tube can more cause the impact to full liquid evaporating area；In addition, full liquid evaporation
The air-flow that area's evaporation generates needs to escape around liquid barrier, causes the air circulation on full liquid evaporating area liquid level slower, visitor
The evaporation rate in this region is reduced in sight.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides one kind and is equipped with liquid barrier but and does not influence full liquid evaporating area
The spray-type evaporator of evaporation.
The technical solution of the utility model are as follows:
A kind of spray-type evaporator, including refrigerant tank body, heat exchanger shell, spraying zone heat exchanger tube, full liquid evaporating area change
Heat pipe and liquid barrier, it is characterised in that: the refrigerant tank body connects heat exchanger shell top, the heat exchanger by inlet tube
Gas-liquid separator and dispenser are equipped with by bracket in shell, the heat exchanger shell is interior and is laid with below dispenser
Spraying zone heat exchanger tube, the heat exchanger shell is interior and is equipped with liquid barrier by bracket below spraying zone heat exchanger tube, described
Liquid barrier is in inverted trapezoidal, and the heat exchanger shell is interior and is laid with full liquid evaporating area heat exchanger tube below liquid barrier；
It is evenly arranged with multiple inverted trapezoidal through-holes on the bottom plate of the liquid barrier, is welded on the inverted trapezoidal through-hole side wall
Keep off the rain piece, and on the left of the piece that keeps off the rain on the left of welding inverted trapezoidal through-hole, there are gaps on the right side of right side and inverted trapezoidal through-hole.
Further, the upper surface of the upright projection covering inverted trapezoidal through-hole of the piece that keeps off the rain, guarantees spraying zone heat exchanger tube
The drop fallen will not be directly through inverted trapezoidal through-hole.
Further, the piece bottom surface of keeping off the rain is welded with flow-guiding bar vertically, and the liquid stream convenient for liquid barrier accumulation can be along
Inverted trapezoidal through-hole keeps off the rain piece and flow-guiding bar carries out flowing to full liquid evaporating area, to reduce drop or liquid stream directly into full liquid
Flow-disturbing caused by evaporating area.
Further, the flow-guiding bar is not contacted with full liquid evaporating area heat exchanger tube.
Further, the refrigerant tank volume surrounding is enclosed with thermal insulation layer.
The utility model further includes exhaust outlet, partition, fixed plate, the disengaging of refrigerating liquid in actual fabrication in addition to above-mentioned component
The components such as mouth are not repeated due to being usual means.Detailed mounting structure can refer to disclosed in Chinese patent a kind of fountain
Evaporator, application No. is 201510504150.0.
The utility model has the following beneficial effects: liquid barrier is equipped with inverted trapezoidal through-hole, due to up-small and down-big, liquid stream generally can
It flows down along side wall, liquid stream is passed through can avoid directly when keeping off the rain piece along piece and the full liquid evaporating area of flow-guiding bar inflow of keeping off the rain
High-altitude drippage causes the intense impact to liquid level, and the boil-off gas that liquid level generates can also escape upwards from inverted trapezoidal through-hole, add
Air circulation on fast liquid level.
