The heat exchanging device can be applied to different heat exchanging fields, in particular to the flue gas residual heat recovering field. The utility model comprises a lower collecting tank, a flue gas side heat exchanging tube bundle arranged on the lower collecting tank, liquid heat exchanging medium arranged on the flue gas side heat exchanging tube bundle, an upper collecting tank arranged above the flue gas side heat exchanging tube bundle, a steam space arranged in the upper collecting tank, a heated medium heat exchanging tube bundle arranged in the steam space, and heated medium accessed into the heated medium heat exchanging tube bundle; a whole space system connected with the steam space is in a vacuum state. The utility model mainly resolves the technical problems of the prior heat tube heat exchanger that the flue gas side heat exchanging tube bundle is easy to be corroded by acid dew points, thereby causing the damage of the equipment, and prolonging the service life of the equipment.
Description
Technical field:
The utility model relates to the heat exchange field, particularly a kind of heat-exchanger rig that adopts the phase transition of vacuum heat exchange, and it can be applied in various heat exchange field, particularly flue gas waste heat recovery field.
Background technology:
Present heat recovery heat exchanger is divided into following several substantially: 1, the most frequently used a kind of be that flue gas and heated medium directly carry out heat exchange, be called conventional heat exchanger; 2, heat exchange of heat pipe is formed heat exchanger by independently single pipe in a large number, heated medium not directly and flue gas heat exchange, behind flue gas and the heat pipe heat exchanging, heat pipe carries out heat exchange with heated medium again.
But the fume side pipeline of existing heat exchange of heat pipe is subjected to acid dew piont corrosion easily, causes the damage of equipment and the reduction in service life.
The utility model content:
The purpose of this utility model is to provide a kind of phase-change heat-exchanger under vacuum state, and the fume side pipeline that mainly solves existing heat exchange of heat pipe is subjected to acid dew piont corrosion easily, causes the technical problem of the damage of equipment, can prolong the service life of equipment.
For achieving the above object, the utility model is achieved in that
A kind of vaccum phase conversion heat exchanger is characterized in that: it comprises the next part case, has the fume side heat-exchanging tube bundle on the next part case, and this fume side heat-exchanging tube bundle has liquid heat transfer medium, and this fume side heat-exchanging tube bundle top has upper collecting chamber; Be the vapor space in this upper collecting chamber, have the heated medium heat-exchanging tube bundle in the lid vapor space, feed heated medium in this heated medium heat-exchanging tube bundle; The whole space system that links to each other with the vapor space all is under the vacuum state.
Described vaccum phase conversion heat exchanger is characterized in that: this fume side heat-exchanging tube bundle is made up of finned-tube bundle.
Described vaccum phase conversion heat exchanger is characterized in that: next part case and upper collecting chamber all are that steel plate is welded.
By said structure, the utlity model has following advantage:
Biggest advantage of the present utility model is can adjust the tube wall temperature of heating surface fume side flexibly by the vapor (steam) temperature of control in the heat exchanger, makes it to be in more than the flue gas acid dew point forever, thereby has thoroughly avoided the acid dew piont corrosion of fume side; Owing to be under the vacuum state, steam side is under the anaerobic state, and heating surface oxygen corrosion can not take place; Steam is in the space of a sealing, can not lose, and can use any water quality, can not produce incrustation scale; Vaccum phase conversion heat exchanger can be used for heating the fluid of other form simultaneously, and this fluid comprises gas and liquid, vapour-liquid heterogeneous fluid; The medium that produces phase transformation in the heat exchanger can be a water, also can be other liquid, can adjust as required.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure:
1-next part case;
2-fume side heat-exchanging tube bundle;
The 3-upper collecting chamber;
The 31-vapor space;
4-heated medium heat-exchanging tube bundle;
The specific embodiment:
See also Fig. 1, it is the structural representation of the utility model vaccum phase conversion heat exchanger.This heat exchanger inner body is under the vacuum state, forms by the heat-exchange tube bundle that installs secondary circuit in the heat exchanger vapor space additional.As shown in the figure: its bag pot next part case 1 is to be welded by steel plate; Fume side heat-exchanging tube bundle 2 is made up of finned-tube bundle; Upper collecting chamber 3 is to be welded by steel plate, and the inside is the vapor space 31; Heated medium heat-exchanging tube bundle 4 is made up of light pipe, and the inside feeds heated medium.Heated medium heat-exchanging tube bundle 4, it can be one or more groups, the inside can lead to as different fluid media (medium)s.
During use, sweep of gases heat-exchanging tube bundle 2, the heat of flue gas are passed to the liquid in the tube bank 2, liquid heat absorption evaporation, and the steam of generation enters upper collecting chamber 3, steam and heat-exchanging tube bundle 4 heat exchange in the upper collecting chamber 3, heat is passed to the heated medium in the tube bank 4; Become liquid after the steam cooling in the upper collecting chamber 3 and get back to heat-exchanging tube bundle 2, heat exchange so repeatedly again.
The course of work of vaccum phase conversion heat exchanger is:
One, water becomes the endothermic process of steam: (utilize water to become the endothermic process of steam, the flue gas liberated heat is passed to steam.) the abundant heat exchange of heating surface of flue gas and vaccum phase conversion heat exchanger.Heat is absorbed the water of passing in the heat exchanger by heating surface, and water is subjected to thermal evaporation to produce steam;
Two, steam becomes the exothermic process of water: (utilize steam to become the exothermic process of water, the heat transferred that steam is contained is heated fluid.) steam evaporation enters the heat-exchanging tube bundle of the vaccum phase conversion heat exchanger top vapor space, undergoes phase transition heat exchange with the heat-exchanging tube bundle wall.Heat is by the absorption of fluids that is heated in the heat-exchanging tube bundle;
Three, the condensed water behind the steam phase transforming relies on self gravitation to fall into hydrospace, vaccum phase conversion heat exchanger bottom, continues to be heated evaporation, so moves in circles.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present utility model.
