Description

A kind of dry evaporator

Technical field

The utility model relates to a kind of dry evaporator, belongs to evaporation equipment technical field.

Background technology

Evaporimeter is a kind of dividing wall type heat-exchange apparatus.For the design of the evaporimeter of larger heat exchange amount, conventional design is exactly the length of increase evaporimeter or increases diameter of the housing and copper pipe quantity.When increasing the length of evaporimeter, water side pressure general who has surrendered increases very large, probably exceeds the safe pressure drop scope of evaporimeter.If drop to zone of reasonableness to reduce water side pressure, just need reduce the quantity of deflection plate or strengthen the corner cut of deflection plate, and like this, the heat exchange property of evaporimeter must will reduce, and does not reach designing requirement.If increase diameter of the housing, increase copper pipe quantity, this kind of method cost will increase a lot.The structure of common dry evaporator as depicted in figs. 1 and 2, water side in cylindrical shell 2 is provided with a water inlet 3 and a delivery port 4 and some deflection plates 1, medium side in cylindrical shell 2, two refrigerant passages are all be designed in the same way, the refrigerant inlet 51 of the first refrigerant passage and the refrigerant inlet 61 of the second refrigerant passage are positioned at the same side (see Fig. 2), the refrigerant gas outlet 52 of the first refrigerant passage and the refrigerant gas outlet 62 of the second refrigerant passage are positioned at the same side (see Fig. 3), and for such design, two Duan Shui side parts of whole evaporimeter, operating mode will not be very average, two Duan Shui side parts of whole evaporimeter, first half is based on evaporator section, latter half is based on superheat section, heat exchange property is uneven.

Utility model content

The purpose of this utility model is to provide a kind of dry evaporator, to solve the problems referred to above existing in prior art.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of dry evaporator, comprise cylindrical shell, described inner barrel comprises water side and medium side, wherein, the outer wall of described water side is provided with two water inlets, is provided with a total delivery port between two described water inlets, described medium side be provided with two flow directions on the contrary to refrigerant passage.

Preferably, described total delivery port and two water inlets are on the same line.

Preferably, described water side is provided with some deflection plates, and described deflection plate is longitudinally arranged.

As further preferred version, the quantity of described deflection plate is 14 pieces.

The beneficial effects of the utility model are mainly reflected in:

1, two ends are adopted to enter two path water, a middle total water outlet in road, the pressure drop of water effluent journey reduces greatly, the heat exchange property that extra deflection plate quantity improves evaporimeter further can be increased like this, like this when evaporimeter length increases few, just can reach designing requirement, cost reduces greatly;

2, be reverse two refrigerant system design.Like this, will compare balance to the internal heat of whole evaporimeter, performance is higher.

Detailed description of the invention

The structure of a kind of dry evaporator that the utility model provides is as Fig. 3, shown in Fig. 4 and Fig. 5, cylindrical shell 2 inside comprises water side and medium side, wherein, the outer wall of water side is provided with two water inlets 3, a total delivery port 40 is provided with between two water inlets 3, total delivery port 40 and two water inlets 3 are on the same line, water side is provided with 14 pieces and longitudinally arranges and the deflection plate 1 be parallel to each other, medium side be provided with flow direction on the contrary to the first refrigerant passage and the second refrigerant passage, the refrigerant inlet 51 of the first refrigerant passage and the refrigerant gas outlet 62 of the second refrigerant passage are positioned at the same side (see Fig. 4), the refrigerant gas outlet 52 of the first refrigerant passage and the refrigerant inlet 61 of the second refrigerant passage are positioned at the same side (see Fig. 5).

Adopt two ends to enter two path water, a middle total water outlet in road, the pressure drop of water effluent journey reduces greatly, the heat exchange property that extra deflection plate quantity improves evaporimeter further can be increased like this, like this when evaporimeter length increases few, just can reach designing requirement, cost reduces greatly;

Be reverse two refrigerant system design.Like this, will compare balance to the internal heat of whole evaporimeter, performance is higher.

In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
