Flue gas is through the first tube bank time, and heat-storing material absorbs the heat in flue gas, and then heat storage medium passes to the heat of absorption the cryogenic media in the second hole, thereby completes heat transfer process.
Because heat-storing material is solid heat storage material, in heat transfer process, do not undergo phase transition, therefore flue gas can, directly through the first hole in heat-storing material, not need in the first hole, tube bank to be set separately, has saved tube bank.Equally, because cryogenic fluid flows in the second hole, and flue gas flows in the first hole, and flue gas and cryogenic fluid cannot directly mix, and has saved the second pipe, provides cost savings.
Described heat-storing material is the material of integral structure.
Preferably, heat-storing material is ceramic heat-storing material.Why adopt ceramic heat-storing material because pottery has corrosion resistance, with traditional arrange tube bank compared with, can prevent that tail gas from the effect of corrosion tube bank occurring simultaneously.
Flue gas and cryogenic media can flow simultaneously, and heat-storing material, in absorbing flue gas heat, transfers heat to cryogenic media.
Certainly select as another, flue gas and cryogenic media can different time sections carry out heat exchange with heat storage medium respectively.In endothermic process, high-temperature flue gas heat release in pipe, heat-storing material storing heat; In the time of heat that needs utilization stores, in the second hole 9, by cryogenic media, absorb the heat of heat storage medium.For example, in the time that high-temperature flue gas intermittence stops, the cryogenic fluid in heat-storing material and the second hole 9 carries out exothermic reaction, realizes storage and the utilization of cement production process waste heat, has improved the utilization rate of the energy.
Preferably the first hole 3 and the second hole be to arrange structures more as one, and two ranked first and between hole 3, arrange one and ranked second hole, and two ranked second and between hole, arrange one and ranked first structure angle setting in 90 ° between 3, the first holes 3, hole and the second hole, as shown in Figure 3.Wherein the distance between the first hole 3 and the second hole 9 center lines can not be excessive, if excessive, can there is no enough heats because of flue gas, cause heat-storing material cannot hold full heat, cause the waste of heat-storing material, also can cause the temperature of outlet 5 flue gases too low simultaneously, cause cold end corrosion; If distance is too small, cause heat-storing material to hold and meet enough heats, cause the demand that cannot meet heat exchange, caused the waste of the energy, therefore, the present invention is the size relationship of the best heat exchanger that sums up of the test data of the heat exchanger by multiple different tube diameters.
Wherein the diameter in the first hole is D1, and the diameter in the second hole is D2, and the distance between the center line in the first hole and the center line in the second hole is L, and D1, D2 and L meet following formula:
L=a* (D1
2+ D2
2)
b, wherein a, b is parameter, wherein 0.98<=a<=1.09,0.54<=b<=0.57;

For above-mentioned situation, but L numerical value now also meets above-mentioned formula.Can adjust the numerical value that L constantly changes by adjusting the size of a, two parameters of b.
As preferably, along flow of flue gas direction, described heat-storing material is given into multistage, and each section is mutually independently, and the difference of the insulation material heat storage capacity by each section realizes the reduction gradually of heat storage capacity.For example can be by the difference of the difference of heat-storing material (comprising composition difference) or accumulation of heat thickness, or both.
As one preferably, control valve 13 is set on the entrance in the second hole 9, for regulating the flow of the medium that enters the second hole 9, simultaneously, export set temperature sensor (not shown) on 1 position at high-temperature flue gas, for measuring the temperature of flue gas of heat exchanger exit; Control valve 13, temperature sensor carry out data with central controller (not shown) and are connected, and center-control, according to the size of the temperature of temperature sensor measurement, regulates the flow of the medium that enters the second hole 9 automatically.
If measure temperature lower than the first temperature, central controller reduces the aperture of control valve automatically, if measure temperature higher than the second temperature, central controller increases the aperture of control valve automatically, wherein the second temperature is greater than the first temperature.
Why take above-mentioned measure, main purpose is in order to prevent cold end corrosion.Because if exhanst gas outlet temperature is too low, can cause flue-gas temperature lower than dew-point temperature, can cause the cold end corrosion to smoke discharging pipe and heat exchanger, participate in the flow of the cryogenic media of heat exchange by minimizing, reduce heat exchange amount, improve outlet temperature, can avoid the generation of cold end corrosion to the control of temperature; In like manner, if the temperature of measuring is higher than uniform temperature, show that exhaust gas temperature is too high, can cause waste, therefore, need to increase the flow of fluid, absorb more heat.
