Description

Unitized exchanger
Technical field
The utility model relates to the heat exchanger apparatus field, relates in particular to a kind of unitized exchanger for condensation of gas.
Background technology
In field of heat exchangers, when gas is carried out condensation, usually adopt spraying condenser, filled type condenser and plate-type condenser to carry out the heat exchange condensation.Adopt above these condensers gas to be carried out adopt cooling water that gas is carried out the heat exchange condensation in the process of heat exchange condensation, this usually causes producing in the cooling duct mineral precipitation more, and condensation effect descends.In addition, because the temperature of water at low temperature is lower, corresponding condensation cost is low higher.If the unified very high low-temperature cooling water of cost that adopts in condensation process, this has just increased the cost of condensation of gas.Therefore, need a kind of sub-cooled water consumption few, the unitized exchanger that condensation effect is good and the condensation cost is low is with the existing deficiency of the condensation method that remedies present heat exchanger.
Summary of the invention
The technical problems to be solved in the utility model is to have heat exchanger, condensation cost more high deficiency good at condensation effect now for overcoming, and existing heat exchanger is improved design, obtains a kind of good effect of heat exchange, low, the energy-conservation unitized exchanger of condensation cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of unitized exchanger is provided, and this unitized exchanger comprises the first heat exchange core and is positioned at the second heat exchange core of this first heat exchange core bottom.The left and right sides of the first heat exchange core is respectively equipped with the first import and the first outlet, and the left and right sides of the second heat exchange core is respectively equipped with the second import and the second outlet.Side is provided with triple feed inlet before and after the first heat exchange core, and the bottom of side is provided with the 3rd outlet before and after the second heat exchange core, and the middle part of side is provided with gas vent before and after this first heat exchange core and the second heat exchange core.
The first preferred version of the present utility model is that the volume of the first heat exchange core is less than the volume of the second heat exchange core.
The second preferred version of the present utility model is that the number of triple feed inlet is a plurality of.
The 3rd preferred version of the present utility model is that the number of the 3rd outlet is a plurality of.
The 4th preferred version of the present utility model is that the first heat exchange core and the second heat exchange core are the aluminum plate-fin type heat exchange core.
Technical advantage of the present utility model is: two heat exchange core stack combinations become a heat exchange integral body owing to adopt up and down, when the cooling medium of two kinds of different temperatures flows through respectively, forming successively cryogenic temperature section and the lower cryogenic temperature section of temperature in two heat exchange cores up and down from two heat exchange cores up and down.These two cryogenic temperature sections can be carried out to the gas that needs are condensed the segmentation cooling.The cryogenic temperature section at first drops to uniform temperature with gas, and the lower cryogenic temperature section of temperature is again to its condensation of further lowering the temperature.This heat exchanger has reduced the consumption of low-temperature cooling water, has improved heat transfer effect, and it is low to have reduced the condensation cost, has saved energy.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the front view of the utility model unitized exchanger embodiment.
Fig. 2 is that the utility model is with the left view of the unitized exchanger embodiment of partial sectional view.
Fig. 3 is the top view of the utility model unitized exchanger embodiment.
The specific embodiment
By the top view of the left view of the front view of unitized exchanger shown in Figure 1, unitized exchanger embodiment with partial sectional view shown in Figure 2 and unitized exchanger shown in Figure 3 as can be known, this unitized exchanger comprises the first heat exchange core 1 and is positioned at the second heat exchange core 2 of this first heat exchange core 1 bottom.The left and right sides that the left and right sides of the first heat exchange core 1 is respectively equipped with the first import 3 and the first outlet 4, the second heat exchange cores 2 is respectively equipped with the second import 5 and the second outlet 6.The first heat exchange core 1 front and back side is provided with triple feed inlet 7, and this triple feed inlet 7 is positioned at the top of the first heat exchange core 1, is conducive to gas and is full of heat exchange core fully.The bottom of the second heat exchange core 2 front and back sides is provided with the 3rd outlet 8, is conducive to be gathered in the condensed water of bottom from the 3rd outlet 8 discharges.The middle part of this first heat exchange core 1 and the second heat exchange core 2 front and back sides is provided with gas vent 9, is convenient to uncooled gas purging.
Wherein, the volume of the first heat exchange core 1 is less than the volume of described the second heat exchange core 2.The number of triple feed inlet 7 is a plurality of, and the number of the 3rd outlet 8 is a plurality of, can increase air inflow, improves condensation rate.
The first heat exchange core 1 and the second heat exchange core 2 are the aluminum plate-fin type heat exchange core, are conducive to the raising of heat exchange efficiency.
When adopting combinations thereof formula heat exchanger that gas is carried out the heat exchange condensation, low-temperature cooling media flows out from the first outlet 4 from the first heat exchange core 1 that the first import 3 enters into the top again, and the low-temperature cooling media that temperature is lower flows out from the second outlet 6 from the second heat exchange core 2 that the second import 5 enters into the below again.In the first heat exchange core 1 and the second heat exchange core 2, two cryogenic temperature sections have been formed thus.The gas that need to be cooled enters from triple feed inlet 7, flows through from the second heat exchange core 2 of the first heat exchange core 1 of top and below successively.After the slightly high cryogenic temperature section of gas temperature is up carried out precooling, continue again to continue further cooling condensation by the lower cryogenic temperature section of the temperature of below.Because precooling speed is faster than condensation rate, so select 1 pair of gas of the first heat exchange core of small volume to carry out precooling, select the gas after the larger 2 pairs of precoolings of the second heat exchange core of volume to carry out the heat exchange condensation, to guarantee that gas has time enough and space and cooling medium heat exchange and condensation in the second heat exchange core 2.Through after the heat exchange, gas is condensed into gradually and is the bottom of fluid accumulation at the second heat exchange core 2, and these liquid just flow out by the 3rd outlet 8.And the gas that can not be condensed accumulates in the top of these two heat exchange cores, flows out from the gas vent 9 at the middle part of the first heat exchange core 1 and the second heat exchange core 2 front and back sides.Because adopt the segmentation cooling, gas has improved the efficient of heat exchange through again condensation after the precooling.In addition, not segmentation of the cooling medium amount ratio cooling that required temperature is lower is carried out the method for condensation and is wanted much less, has also saved the energy thereby reduced cost.
The utility model is not limited to the above-described embodiment and examples, in the ken that the art personnel possess, can also make a variety of changes without departing from the inventive concept of the premise.
