Abstract
The composite phase-change heat exchanger consists of two parts, including air preheater and phase-change heat exchanger, and the condensing chamber and evaporating chamber in the phase-change heat exchanger are integrated. The one-way valve is used for replacing the original vacuum pump, the structure is compact, the cost is greatly reduced, two energy forms of hot air and hot water with higher temperature can be simultaneously provided, and the heat engineering energy-saving device is used for recovering the waste heat of the flue gas discharged by heat equipment such as a boiler and the like.
Description
The utility model relates to a kind of thermal energy-saving equipment, is used to recycle the waste heat of flue gases that hot equipment discharges such as boiler.
The utility model is with a kind of vacuum heat exchanger of daily magazine " chemical devices " 1981.6 interim reports the most relevant correlation technique as it.The primary structure of this vaccum phase conversion heat exchanger as shown in Figure 2.Whole device is made up of vaporization chamber 10 and condensation chamber 15 two parts, is horizontally installed with screw thread flue tube 16 in the vaporization chamber, is horizontally installed with condenser pipe 14 in the condensation chamber, and the top of condensation chamber connects a vavuum pump 13.When the useless flue gas of the low temperature of the hot equipment exhausting of boiler one class by direction 11 during by flue tube 16, make the aqueous vaporization in the vaporization chamber, water vapour under the fluidized state enters condensation chamber, water 12 heating with the condenser pipe of flowing through, obtain the hot water more than 80 ℃, this part hot water except can returning boiler, can also directly be used as the process water in light textile, the chemical industry owing to the hot water temperature's height than economizer gained.Can get rid of as the not concretive gas of air one class before the purpose that vavuum pump is set is to make vaccum phase conversion heat exchanger to start, and vaporization chamber is controlled under the little negative pressure work.To keep the boiling temperature of certain vaporization chamber.Because vaccum phase conversion heat exchanger has advantages such as organic efficiency height, Corrosion Protection are good, safe and reliable to operation, some countries and China the Northeast have obtained using widely in Europe.The part but this vaccum phase conversion heat exchanger also comes with some shortcomings:
1, vaporization chamber and condensation chamber are separated from each other, and make that whole device volume is bigger, and have increased the flow resistance of steam.
2, because of being provided with vavuum pump and electrical equipment control device correspondingly, make that the cost of whole device is higher, vavuum pump can only make vaporization chamber be under the negative pressure in addition, water boiling temperature in the vaporization chamber is lower, makes water temperature after the heating can't satisfy the requirement of the higher industrial water of domestic water and some temperature requirements.
3, useless flue gas passes through from spiral flue tube 16, and its flow resistance is bigger, easily produces dust deposition, and the flue dust cleaning operation is very inconvenient.
4, can only provide hot water single energy form.
The purpose of this utility model just is to overcome above-mentioned weak point of the prior art, make in the device that is provided, useless flue gas can the pipeline from vaporization chamber outside cross-flow tube bank by to reduce the flow resistance of useless flue gas, vaporization chamber and condensation chamber are monoblock type reducing the volume of device, and replace original vavuum pump with the cost that reduces device and the temperature of the water after improving heating with a check valve.
The purpose of this utility model reaches by following measures: whole device is made up of two parts, and a preceding part is an air preheater, and a back part is a phase-change heat-exchanger; The top of phase-change heat-exchanger is condensation chamber, and the bottom is a vaporization chamber, and two Room are combined and formed a whole case structure, in the interior space that pipeline of vertically installing in the vaporization chamber and vaporization chamber constitute water are housed; A check valve is equipped with at the top of condensation chamber.
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
Fig. 1 is a general structure sketch of the present utility model.Whole device is made up of air preheater 1 and phase-change heat-exchanger 6 two parts.The top of phase-change heat-exchanger is that condensation chamber 5, bottom are that formation one whole case structure is combined in vaporization chamber Room 3, two; Pipeline 2 in the vaporization chamber is vertically installed, and in the interior space that it and vaporization chamber constitute water is housed; The intermediate lateral of condensation chamber is equipped with condenser pipe 4, and a check valve 7 is equipped with at the top.During work, the useless flue gas that hot equipment discharged of boiler one class at first enters air preheater with direction 8 makes the air by pipeline 9 obtain preheating, and the air after this part preheating will be carried the back boiler burner hearth, improve its burning condition, improves coal adaptability.The outlet flue gas of air preheater directly enters phase-change heat-exchanger, flue gas cross-flow tube bank outside the pipeline 2 of vaporization chamber passes through, theoretical calculation analysis and experiment show that this structure configuration can improve the heat transfer efficiency of phase-change heat-exchanger, reduce the heat transfer area of phase-change heat-exchanger greatly, and this structure descends flue dust deposition rate and make the flue dust cleaning operation simple and convenient; Flue gas makes the aqueous vaporization in the vaporization chamber, and the water vapour under the fluidized state enters condensation chamber, and the cold water in the condenser pipe of flowing through is heated.Owing to check valve has been installed at the top of condensation chamber, so phase-change heat-exchanger can be under a pressure-fired or the negative pressure and work during work, so not only satisfied and got rid of the requirement that may enter not concretive gas in the phase-change heat-exchanger, and the water in the vaporization chamber can be according to working under the difference that adds the hot water amount pressure-fired that maintains check valve automatically and allowed and the saturation state that has the certain vacuum degree, its boiling temperature is higher, the cold water of the condenser pipe of flowing through can be heated to more than 80 ℃, use for life and production.From the model machine ruuning situation of development, being provided with of check valve can be satisfied above-mentioned requirements, enters other follow-up equipment again through the flue gas of phase-change heat-exchanger.
Compared with prior art, the utlity model has following advantage:
1, vaporization chamber and condensation chamber are integral combined, and whole device volume is little, make, install simple and convenient.
2, save vavuum pump and electrical equipment control device correspondingly, greatly reduced the cost of device.
3, adopt a check valve to make phase-change heat-exchanger be in work under the minute-pressure, improved the temperature that adds hot water.
4, adopt the outer cross-flow tube bank of the pipeline of flue gas from vaporization chamber to pass through, except augmentation of heat transfer greatly, and reduce flow resistance and also can reduce flue dust deposition rate in addition, and make the flue dust cleaning operation simple and convenient.
5, can provide hot-air and hot water two kinds of form of energy.
