Abstract

The invention discloses a tail gas flow direction control system and belongs to the technical field of household life equipment. The tail gas flow direction control system comprises a boiler, exhaust pipes, a water tank, a heat exchange device, a control tube, a control body, a moving body, a fixing body, and a spring, wherein the heat exchange device is arranged in the water tank; the air inlet of the heat exchange device and the air outlet thereof are respectively connected with the air outlet of a second exhaust pipe and the air inlet of a third exhaust pipe; left and right walls of the control body are respectively communicated with the air outlet of a fourth exhaust pipe and the air outlet of a fifth exhaust pipe, the moving body and the fixing body are uniformly arranged in the control body, an upper triangular structure is arranged on the moving body and a lower triangular structure is arranged on the fixing body, and the upper wall of the moving body is connected with the lower wall of the fixing body through the spring. According to the tail gas flow direction control system, when water in the water tank is relatively much, more boiler exhaust gas flows into the heat exchange device; when water in the water tank is relatively little, less boiler exhaust gas flows into the heat exchange device. The tail gas flow direction control system is rational in design and simple in structure, and thus the tail gas flow direction control system is applied to the design of a domestic boiler waste heat recovery system.

Description

Exhaust gas flow direction control system
Technical field
The invention belongs to family expenses living facilities technical field, specifically, is a kind of exhaust gas flow direction control system that can reclaim home dwarf boiler waste heat.
Background technology
Boiler is a kind of energy conversion, and the energy to boiler input has the forms such as the heat energy of chemical energy in fuel, electric energy, high-temperature flue gas, and through boiler conversion, outwards exports steam, high-temperature water or the organic heat carrier with certain heat energy.The hot water produced in boiler or steam directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by Steam Power Equipment, or by generator, mechanical energy are converted to electric energy again.Domestic boiler refers to the domestic life boiler of domestic heating or bathing, and its volume is little, energy consumption is low, and characteristic feature is exactly be applicable to family to use.In the northern country area of China, central heating also cannot realize.Along with the raising of life in the countryside level, residential coal combustion arcola is more and more general, and arcola both can be used for cooking, and also can be used for warming oneself.Household small boiler generally based on fire coal, boiler discharge exhaust in also with a large amount of heats.If this part heat is not used, they will be discharged in air and go, and cause the waste of the energy.In the prior art, some technology provide the scheme of the water utilized in heating exhaust gas water tank.But in these schemes, the water no matter in water tank is many or water is few, is all fixing exhaust gas heat exchanging.Cold or overheated with regard to causing the water in water tank to cross like this.How to make the water temperature in water tank control more accurate, water temperature is suitable for rural household (wash one's face, wash one's hands, have a bath), and this is a trend of home dwarf boiler design.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of exhaust gas flow direction control system, the domestic boiler water temperature be vented in water tank can be made to be applicable to family daily life and use.
The present invention is achieved through the following technical solutions, the present invention includes boiler, downtake pipe, trunnion, second exhaust pipe, water tank, 3rd blast pipe, filling pipe, adjutage, heat exchanger, 4th blast pipe, 5th blast pipe, control valve, control volume, moving body, fixed body, spring, the exhaust outlet of boiler is connected with the air inlet of downtake pipe, the porting of trunnion respectively with downtake pipe gas outlet, second exhaust pipe air inlet is connected, filling pipe, adjutage is arranged in the upper and lower side of water tank, and heat exchanger is arranged in water tank inside, the air inlet/outlet of heat exchanger respectively with the gas outlet of second exhaust pipe, the air inlet of the 3rd blast pipe is connected, and the air inlet of the 4th blast pipe is connected with the gas outlet of downtake pipe, and the air inlet of the 4th blast pipe is positioned at the below of trunnion, the left and right wall of control volume respectively with the 4th blast pipe gas outlet, 5th blast pipe air inlet is connected, moving body, fixed body is arranged in control volume, and with upper three-legged structure on moving body, with lower triangular structure on fixed body, the internal face of fixed body and control volume is consolidated, and the upper wall surface of moving body is connected with the lower wall surface of fixed body by spring.
The invention has the beneficial effects as follows: the present invention is reasonable in design, structure is simple; The present invention can make full use of the waste heat of home dwarf boiler, also can make the relatively more suitable family expenses of the water temperature in water tank.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of A-A section in Fig. 1;
Label in accompanying drawing is respectively: 1, boiler, and 2, downtake pipe, 3, trunnion, 4, second exhaust pipe, 5, water tank, the 6, the 3rd blast pipe, 7, filling pipe, 8, adjutage, 9, heat exchanger, 10, the 4th blast pipe, the 11, the 5th blast pipe, 12, control valve, 13, control volume, 14, moving body, 15, fixed body, 16, spring.
Detailed description of the invention
Elaborate to embodiments of the invention below in conjunction with accompanying drawing, the present embodiment, premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
embodiment
Embodiments of the invention as depicted in figs. 1 and 2, the present invention includes boiler 1, downtake pipe 2, trunnion 3, second exhaust pipe 4, water tank 5, 3rd blast pipe 6, filling pipe 7, adjutage 8, heat exchanger 9, 4th blast pipe 10, 5th blast pipe 11, control valve 12, control volume 13, moving body 14, fixed body 15, spring 16, the exhaust outlet of boiler 1 is connected with the air inlet of downtake pipe 2, the porting of trunnion 3 respectively with downtake pipe 2 gas outlet, second exhaust pipe 4 air inlet is connected, filling pipe 7, adjutage 8 is arranged in the upper and lower side of water tank 5, and it is inner that heat exchanger 9 is arranged in water tank 5, the air inlet/outlet of heat exchanger 9 respectively with the gas outlet of second exhaust pipe 4, the air inlet of the 3rd blast pipe 6 is connected, and the air inlet of the 4th blast pipe 10 is connected with the gas outlet of downtake pipe 2, and the air inlet of the 4th blast pipe 10 is positioned at the below of trunnion 3, the left and right wall of control volume 13 respectively with the 4th blast pipe 10 gas outlet, 5th blast pipe 11 air inlet is connected, moving body 14, fixed body 15 is arranged in control volume 13, with upper three-legged structure on moving body 14, with lower triangular structure on fixed body 15, fixed body 15 is consolidated with the internal face of control volume 13, and the upper wall surface of moving body 14 is connected by the lower wall surface of spring 16 with fixed body 15.
In the implementation process that this is bright, when the water in water tank 5 is more, volume cavity pressure below moving body 14 is also larger, moving body 14 moves up and Compress Spring 16, circulation area between 4th blast pipe 10, the 5th blast pipe 11 diminishes, and what flow out from second exhaust pipe 4, heat exchanger 9 in boiler exhaust gas is more.When the water in water tank 5 is less, volume cavity pressure below moving body 14 is also less, under the elastic reaction of spring 16, moving body 14 moves down, circulation area between 4th blast pipe 10, the 5th blast pipe 11 becomes large, and what flow out from second exhaust pipe 4, heat exchanger 9 in boiler exhaust gas is less.
