Description
Technical field
The utility model relates to waste heat boiler technical field, is specially a kind of two medium waste heat boiler.
Background technology
waste heat boiler is the boiler that the heat produced after utilizing the waste heat in the waste gas in various industrial process, waste material or waste liquid and combustible burning thereof is heated to water certain working medium, and it has good energy-conserving action because greatly improving the utilization rate of the heat of fuel combustion release.Conventional waste heat boiler mostly is single heat transfer medium, as waste heat steam boiler, waste heat boiler of organic heat carrier, but in actual production life, often occur that both having needed to produce superheated steam by steam boiler is used as producing power, need again to provide hot water for the situation of heating by hot-water boiler, if arrange two boilers in this case, not only equipment cost is high, and causes energy consumption large, cannot reach the requirement of current energy-saving and emission-reduction.
Summary of the invention
For the problems referred to above, the utility model provides a kind of two medium waste heat boiler, it, not only simultaneously for industrial production provides superheated steam but also can provide heating hot water simultaneously, thus effectively can reduce boiler and purchase and operating cost, and can greatly reduce expending and disposal of pollutants of the energy.
Its technical scheme is such, it comprises waste heat boiler flue and drum, described waste heat boiler flue level is installed on support, described waste heat boiler flue one end is provided with residual heat high-temperature gas approach, the other end is provided with exhanst gas outlet, described exhanst gas outlet connects chimney, superheater is disposed with along flow of flue gas direction in described waste heat boiler flue, evaporimeter, economizer, high-temperature flue gas enters described waste heat boiler flue from described residual heat high-temperature gas approach, wash away described superheater successively, evaporimeter, air is entered from described exhanst gas outlet through described chimney after the vertical tube bundle of economizer, it is characterized in that: the convection section that boiler of organic heat carrier is also set in described waste heat boiler flue, described boiler of organic heat carrier convection section is arranged at the rear portion of the described economizer along flow of flue gas direction.
It is further characterized in that:
One end of described boiler of organic heat carrier convection section is oil-out, the other end is oil return opening;
The delivery port of described economizer is connected by pipeline with described drum, described drum is connected to form closed circuit by down-comer, tedge and described evaporimeter, described drum is connected with described superheater by top jet chimney, the steam (vapor) outlet external superheated steam mother pipe of described superheater.
The beneficial effect of of the present utility model pair of medium waste heat boiler is: its structure is simple, two kinds of heating surfaces are provided with in flue, thus the high-temperature flue gas produced by prosomite simultaneously water, conduction oil two media is heated, thus reach the superheated steam that is both and is provided for producing and the object of hot water for heating of living, operating cost purchased by effective minimizing boiler, and can greatly reduce energy resource consumption and disposal of pollutants.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the two medium waste heat boiler of the utility model.
Detailed description of the invention
See Fig. 1, the two medium waste heat boiler of the utility model comprises waste heat boiler flue 1 and drum 2, waste heat boiler flue 2 level is installed on support 3, waste heat boiler flue 1 one end is provided with residual heat high-temperature gas approach 4, the other end is provided with exhanst gas outlet 5, exhanst gas outlet 5 connects chimney 6, superheater 7 is disposed with along flow of flue gas direction in waste heat boiler flue 1, evaporimeter 8, economizer 9, high-temperature flue gas enters in waste heat boiler flue 2 from residual heat high-temperature gas approach 4, wash away superheater 7 successively, evaporimeter 8, air is entered from exhanst gas outlet 5 through chimney 6 after the vertical tube bundle of economizer 9, in waste heat boiler flue 1, boiler of organic heat carrier convection section 10 is also set, boiler of organic heat carrier convection section 10 is arranged at the rear portion of the economizer 9 along flow of flue gas direction, one end of boiler of organic heat carrier convection section 10 is oil-out 11, the other end is oil return opening 12, the delivery port of economizer 9 is connected by pipeline 13 with drum 2, drum 2 is connected to form closed circuit by down-comer 14, tedge 15 with evaporimeter 8, drum 2 is connected with superheater 7 by top jet chimney 16, and the superheated steam of superheater 7 exports external superheated steam mother pipe.
Specifically describe the running of the two medium waste heat boiler of the utility model below:
Fume side, the high-temperature flue gas that prosomite produces enters in waste heat boiler flue 2 through residual heat high-temperature gas approach 4, and enters chimney 6 through exhanst gas outlet 5, finally enter air after washing away superheater 7, evaporimeter 8, the vertical tube bundle of economizer 9 and boiler of organic heat carrier convection section 10 successively;
Carbonated drink side, first deaerated water enters economizer 9 and in economizer 9, absorbs heat and be warmed up to and enter drum 2 a little less than after the saturation temperature under drum pressure, enter evaporimeter 8 along the down-comer 14 below drum 2 thus absorb heat after the water entering drum 2 mixes with the saturation water in drum 2 and start to steam, the saturation water entering evaporimeter 8 under normal circumstances only has part directly to become steam, what thus flow in evaporimeter 8 is steam water interface, steam water interface leaves evaporimeter 8 by tedge 15 and enters drum 2 and be separated by the water separator on drum 2 top, wherein isolated water is fallen the hydrospace in drum 2 and is again entered evaporimeter 8 by down-comer 14 and absorbs heat generation steam water interface, isolated saturated vapor then to be entered in superheater 7 by top jet chimney 14 and absorb heat make saturated vapor become superheated steam after from superheated steam outlet flow into the female pipe of superheated steam for the production of,
Mineral oil closed cycle in boiler of organic heat carrier convection section, mineral oil enters convection section from oil return opening and flows out from oil-out, flue gas after superheater 7, evaporimeter 8, economizer 9 again by boiler of organic heat carrier convection section after temperature be down to about 150 DEG C, simultaneously to the mineral oil heating in boiler of organic heat carrier convection section, be used for heating respective media or heating for residential area hot water being provided.
