Abstract

The utility model discloses a spiral pipe sandwiched tail gas waste heat collecting device, comprising a barrel provided with a tail gas inlet and a tail gas outlet on both ends, wherein a barrel wall of the barrel is a hollow structure, a spiral pipe is arranged in an inner chamber of the barrel, the both ends of the spiral pipe are respectively communicated with a water inlet pipe and the inner chamber of the barrel wall, and a steam outlet pipe communicated with the inner chamber of the barrel wall is arranged on the outer wall of the barrel. The normal temperature water, which enters the spiral pipe sandwiched tail gas waste heat collecting device, is heated by the spiral pipe and an interlayer twice, the heating area is nearly double the conventional utility model, and the heating effect is extremely remarkable. The heat of the tail gas can be employed and recycled under a working condition of lower temperature of the tail gas, so that the waste of the heat of the tail gas is avoided. By actual measurement, the spiral pipe sandwiched tail gas waste heat collecting device, disclosed by the utility model, can recycle about 70% of the waste heat of the tail gas of an internal combustion engine. The spiral pipe sandwiched tail gas waste heat collecting device, disclosed by the utility model, has the advantages of simple structure and reasonable design, the blank of such collecting device is filled up, and the spiral pipe sandwiched tail gas waste heat collecting device is beneficial to popularization and application.

Description

Volute sandwich-type using waste heat from tail gas collecting device

One, technical field

The utility model belongs to field of energy-saving technology, is specifically related to a kind of volute sandwich-type using waste heat from tail gas collecting device.

Two, background technique

Internal-combustion engine is a kind of power source of the product that consumes petroleum, and begins in 20th century to promote, and it is estimated that up till now the whole world has tens00000000 internal-combustion engines.Because the narrow limitation of internal-combustion engine existence itself, its thermal efficiency is merely 20%-30%, has 55% energy to discharge from tail gas with the greenhouse gases form approximately, not only waste energy, and befouling environment.In order to address the above problem, the claimant once applied for " a kind of using waste heat from tail gas of internal combustion engine recovering device " (application number: 201120007895.3) on January 12nd, 2011.But find in practice, when this device is used for some internal-combustion engine (especially diesel engine),, caused the waste of exhaust heat-energy because structural deficiency under the lower operating mode of exhaust temperature, is difficult to play and well adopts thermal effect.

Three, summary of the invention

The purpose of the utility model provides a kind of simple in structure, reasonable in design, and it is good to adopt thermal effect, can avoid the volute sandwich-type using waste heat from tail gas collecting device of exhaust heat-energy waste effectively.

In order to solve above-mentioned purpose; The technological scheme that the utility model adopts is: this device comprises that two ends are respectively the cylindrical shell of tail gas inlet/outlet; Be characterized in: the barrel of cylindrical shell is a hollow structure; Be provided with volute in the cylinder lumen, the two ends of this volute communicate with the inner chamber of intake pipe and barrel respectively, on cylinder body outer wall, are provided with the steam outlet pipe that communicates with the barrel inner chamber.

Adopt said structure, during use, the tail gas import and the internal-combustion engine vent-pipe of the utility model joined; Normal-temperature water is injected from intake pipe; Water is heated into water vapor by the waste heat in the tail gas when flowing through volute, when water vapor gets into the inner chamber of barrel; Heated by the waste heat in the tail gas once more, thereby become dry steam.Dry steam carries the exhaust heat-energy that is recovered, and sends into the place that needs heat energy, has realized the purpose of energy-saving and emission-reduction.Because get into normal-temperature water process volute and twice heating of interlayer in the utility model, the more preceding utility model patent of heating area nearly doubles, and adopts thermal effect very significantly.Under the lower operating mode of exhaust temperature, also can well adopt recovery to the heat energy of tail gas, avoided the waste of exhaust heat-energy.Through actual measurement, the recyclable using waste heat from tail gas of internal combustion engine about 70% of the utility model.The utility model is simple in structure, and is reasonable in design, replenished the blank of this type of collecting device, is worthy of popularization.

Four, description of drawings

Accompanying drawing is the structural representation of the utility model.

Five, embodiment

As shown in the figure, the utility model comprises that two ends are respectively the cylindrical shell 1 of tail gas inlet/outlet 8,9.The barrel of cylindrical shell 1 is a hollow structure, and promptly the inside and outside wall of cylindrical shell 1 is a sleeve structure.Be provided with volute 3 in cylindrical shell 1 inner chamber, the two ends of this volute 3 communicate with the intake pipe 2 and the barrel inner chamber 4 in cylindrical shell 1 outside respectively.On cylindrical shell 1 outer wall, be provided with the steam outlet pipe 5 that communicates with barrel inner chamber 4.In cylindrical shell 1 inner chamber, be provided with by volute 3 around turbolator 6, this turbolator 6 can make the tail gas shape eddy current that gets in cylindrical shell 1 inner chamber, prolongs the flushing time of tail gas, increases the heat exchange stroke of tail gas, absorbs using waste heat from tail gas so that gather better.Turbolator 6 is fixed on the inwall of cylindrical shell 1 through support 7.For reduce tail gas through the time resistance, turbolator 6 is designed to cone structure, its cone angle is towards tail gas import 8.Volute 3 is a cascaded structure with barrel inner chamber 4, and can reach the spatial position situation as required, is designed to one or interconnective many.
