It should be noted that herein, in Fig. 1, water inlet pipe 13 and outlet pipe 11 are liquid for the flow direction of heat removing tube 102, the mounting means that can certainly carry moving device according to dewfall smoke heat energy not defines, for example, because liquid self has constant weight, therefore conventionally dewfall smoke heat energy does not carry moving device and settles in vertical direction, now outlet pipe 11 also can be called tedge, and water inlet pipe 13 also can be called down-comer.
When practical application, fluid temperature in heat removing tube 102 remains on the numerical value higher than flue gas dew point, be specifically as follows by test and technical staff's experience, determine higher than 5 degrees Celsius of flue gas dew points (℃), certainly, also can be other reasonable numerical value, for example, in the deviation of 1 degree Celsius of 5 degrees Celsius of upper and lower existence, 5 ± 1 ℃.Now, the liquid entering in evaporimeter 12 by outlet pipe 11 from heat removing tube 102 is also higher than 5 degrees Celsius of flue gas dew points, and in evaporimeter, there is Evaporation Phenomenon, the state coexisting for water, vapour in evaporimeter 12, thereby the saturation temperature that need to guarantee the liquid in evaporimeter 12 maintains higher than 5 degrees Celsius of flue gas dew points, therefore, can complete by the evaporation capacity of controlling in evaporimeter 12.
Particularly, as shown in Figure 1, on the evaporation tube 15 that one end is communicated with evaporimeter 12, can be provided with the first adjuster 151, also can be called evaporation flow regulator, this first adjuster 151 is connected with robot control system(RCS) 21, thereby by robot control system(RCS) 21, control to adjust the first adjuster 151, thereby complete the control of the interior liquid evaporation amount of evaporimeter 12.Wherein, the first adjuster 151 can be a simple construction of switch, thus robot control system(RCS) 21 can control the opening degree of this construction of switch and complete control, can certainly be other electronic equipments etc.
In addition, when controlling the first adjuster 151 by robot control system(RCS) 21, it controls parameter can be the pressure in evaporimeter 12.Be specifically as follows, on evaporimeter 12 is interior, be provided with pressure detecting instrument 121, it can be the equipment such as pressure transmission device, thereby be connected with robot control system(RCS) 21 by pressure detecting instrument 121, the numerical value detecting is sent in robot control system(RCS) 21, robot control system(RCS) 21 can be controlled the first adjuster 151 according to this numerical value, for example, when pressure in the evaporimeter 12 that pressure detecting instrument 121 detects is larger (comparing with the pressure value presetting), feed back in robot control system(RCS) 21, and control the first adjuster 151 steam flow is increased; Pressure in the evaporimeter 12 that pressure detecting instrument 121 detects is hour (comparing with the pressure value presetting), contrary with above-mentioned control procedure.
When the steam in evaporimeter 12 enters into thermal energy converter 14 by steam pipe 15, by steam, to cryogenic media, heat, thereby output high-temperature medium completes the utilization of heat energy.Particularly, thermal energy converter 14 one end are provided with input channel 17, and cryogenic media enters thermal energy converter 14 from input channel 17, and flows in the flow duct in thermal energy converter 14, the last high-temperature medium afterwards of heating of exporting from output channel 18.Wherein, can on the outer wall of flow duct, along its bearing of trend, be wound around water back, this water back one end is connected with steam pipe 15, the other end is connected with condenser pipe 16, thereby steam flows in water back, and give the heating of the cryogenic media in flow duct, cryogenic media absorbs the heat of steam, makes steam-condensation become aqueous water, and finally from the water back other end, flow back into condenser pipe 16, and and then enter in evaporimeter 12.In this process, Condensation can be the condensation under saturated vapor, its temperature change is very little, and certainly under other states, the temperature of condensed liquid may reduce, lower than flue gas dew point, when it flows in evaporimeter 12 by condenser pipe 16, the whole temperature that reduces liquid in evaporimeter 12 of meeting, but because the content liquid in evaporimeter 12 is more, therefore in the short time, can not change, and can guarantee to flow into temperature in heat removing tube 102 higher than flue gas dew point by subsequent adjustment.
Wherein, the cryogenic media heating in thermal energy converter 14 can be aqueous water, can be also gas or other flowable material.In addition, in thermal energy converter 14, when heating, may produce excessive pressure and thermal energy converter 14 is caused to damage, also can as shown in Figure 1 outlet 19 be set in thermal energy converter, thus the pressure in time in balance thermal energy converter 14.
Yet, in the long-term process of using, owing to can being dissolved with oxygen in liquid, the noncondensing gaseous state such as hydrogen, the work of therefore carrying moving device at dewfall smoke heat energy is not done in process, this portion gas also can be taken away a part of steam and discharge, cause going out of liquid in evaporimeter 12, enter imbalance, therefore as shown in Figure 1, filling pipe 22 can be set in evaporimeter 12, this filling pipe 22 is provided with the second adjuster 221, and the second adjuster 221 is connected with robot control system(RCS) 21, thereby robot control system(RCS) 21 is by controlling the second adjuster 221, can control filling pipe 22 in good time to the interior feeding-in liquid of evaporimeter 12, to regulate the liquid level of evaporimeter 12 interior liquid.
Specifically in when application, can be by peephole and rule are set on evaporimeter 12, and the routine observation by technical staff completes moisturizing and operates, and also can on evaporimeter 12, Level meter be set, this Level meter is connected with robot control system(RCS).Level meter can detect in real time the liquid level of liquid in evaporimeter 12 and detected value is fed back in robot control system(RCS) 21, to facilitate record and to control as required the second adjuster 221, controls unlatching, closure and the opening degree etc. of filling pipe 22.
It should be noted that, flowing liquid in heat removing tube 102, evaporimeter 12 and each pipeline, can be desalted water herein, and desalted water has the not feature of burn into good effect of heat exchange, certainly, can be also other rational liquid.
