Abstract
The utility model discloses a novel heat-exchange reheater, which is arranged on a horizontal flue and comprises a heat-absorbing unit and a reheater. The condensate performs heat exchange with the flue gas after entering the heat-absorbing unit, then is phase changed into the steam, the steam coming out of the heat-absorbing unit enters the reheater through a reheating pipe and performs farther heat exchange with the flue gas so as to lead the heat exchange to be sufficient and increase the steam temperature, thereby leading the heat with the low heat value to be transferred to the heat withthe high heat value, fully utilizing the waste heat of the flue gas, improving the heat exchange efficiency, and also leading a subsequent heating medium to be improved to the designed temperature.
Description
Technical field
The utility model relates to a kind of heat transmission equipment, specifically a kind ofly can make heat exchange heat transmission equipment more fully.
Background technology
Traditional heat exchanger only has heat absorbing units, heat exchange is abundant inadequately, do not utilize fume afterheat fully, heat exchange efficiency is not high, vapor (steam) temperature is not high, and what heat exchange obtained is low-calorie heat, the steam of this part low heat value heat and follow-up during with the hot working fluid heat exchange, temperature with hot working fluid can't be brought up to setting value, make the utilization of this part low-calorie heat be subjected to limitation.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of novel heat exchange reheater, this novel heat exchange reheater can make heat exchange more abundant, improved vapor (steam) temperature, thereby can make of the heat conversion of low-calorie heat to high heating value, utilized fume afterheat more fully, improved heat exchange efficiency, also made the follow-up temperature of bringing up to design with thermal medium.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of novel heat exchange reheater, this novel heat exchange reheater is installed on the horizontal flue, comprise heat absorbing units and reheater, to use direction to be benchmark, described heat absorbing units is by last, water drum and convection bank are formed, described reheater is by the reheater lower collecting box, reheater outlet header and reheater convection tube are formed, the water drum of described heat absorbing units communicates with the condensation water feed tube, be communicated with heat pipe again between the steamdrum of described heat absorbing units and described reheater lower collecting box, described reheater outlet header communicates with the steam guiding tube that leads to thermal medium.Condensation water enters after the heat absorbing units and flue gas generation heat exchange, and becomes steam mutually, and the steam that comes out from heat absorbing units enters the reheater through heat pipe and carries out further heat exchange with flue gas.
The beneficial effects of the utility model are: condensation water enters after the heat absorbing units and flue gas generation heat exchange, and become steam mutually, the steam that comes out from heat absorbing units enters the reheater through heat pipe and carries out further heat exchange with flue gas, make heat exchange more abundant, improved vapor (steam) temperature, thereby can make of the heat conversion of low-calorie heat, utilized fume afterheat more fully to high heating value, improved heat exchange efficiency, also made the follow-up temperature of bringing up to design with thermal medium.

Fig. 1 is the utility model principle schematic.
The specific embodiment
Embodiment: a kind of novel heat exchange reheater, this novel heat exchange reheater is installed on the horizontal flue 6, comprise heat absorbing units and reheater, to use direction to be benchmark, described heat absorbing units is by last, water drum 11,12 and convection bank 13 form, described reheater is by reheater lower collecting box 21, reheater outlet header 22 and reheater convection tube 23 are formed, the water drum of described heat absorbing units communicates with condensation water feed tube 3, be communicated with heat pipe 4 between the steamdrum of described heat absorbing units and described reheater lower collecting box, described reheater outlet header communicates with the steam guiding tube 5 that leads to thermal medium again.Condensation water enters after the heat absorbing units and flue gas generation heat exchange, and become steam mutually, the steam that comes out from heat absorbing units enters the reheater through heat pipe and carries out further heat exchange with flue gas, make heat exchange more abundant, improved vapor (steam) temperature, thereby can make of the heat conversion of low-calorie heat, utilized fume afterheat more fully to high heating value, improved heat exchange efficiency, also made the follow-up temperature of bringing up to design with thermal medium.
