Description

Utilize tail gas to adopt the automobile-used heating plant of heat

Technical field

The utility model relates to heating system, belongs to the improvement of automobile-used heating arrangement structure, particularly utilizes tail gas to adopt the automobile-used heating plant of heat.

Background technology

In the prior art field, when passenger vehicle is warmed oneself in the winter time, a kind of heater unit of fuel oil electric consumption is arranged, its cost height, device structure complexity, and per hour oil consumption more than 1 liter, use uneconomically, hear rate can be high, and its exhaust emission is also very serious in addition, be easy to cause the storage battery electric weight deficit of power supply equally, influence the service life of storage battery, also can cause the driving engine cisco unity malfunction sometimes, the heat temperature of heating is not high yet; When driving engine is in low temperature, just there is not warm braw to supply with yet.In addition, also has a kind of native warming device, its structure is for directly to tap into the compartment with waste pipe, but this native heating installation is very dangerous, be easy to scorch the clothing of passenger's dress or scald the passenger, and the native warming device of this kind gas of discharging be the formation after the indoor work done burning of engine combustion objectionable impuritiess such as hydro-carbon, oxides of nitrogen and carbonic oxide in the car by bus personnel's health cause serious harm, and its noise is big.

The utility model content

The purpose of this utility model is to provide a kind of automobile-used heating plant that utilizes tail gas to adopt heat, it is simple in structure, making full use of the residual heat of heat energy that tail gas carries is heat supply in the car, heating, energy-saving and cost-reducing, cost is low, economic environmental protection, gas supplied sheerly is an air in its warm braw, promptly can not pollute air in the car.

The purpose of this utility model is achieved in that a kind of automobile-used heating plant that utilizes tail gas to adopt heat, comprise exhaust pipe, the upper port of exhaust pipe is connected with the exhausr port of engine chamber, the backheat sleeve pipe in the exhaust pipe outer wrap, on end periphery and the wall of exhaust pipe periphery wall around closed end the hot gas delivery port is being set on the backheat sleeve pipe, the hot gas delivery port is communicated with heat supply, heating system; Be spaced from each other by dividing plate with the terminal host box that is communicated with of exhaust pipe exhausr port and with the terminal secondary machine box that is communicated with of backheat sleeve pipe admission port, drain pipe overflow pipe is being set on the host box, the air inlet openings of aspirated air is being set on the secondary machine box; Be installed in the rotary actuator on the dividing plate, the active impeller of installing at the one end is positioned at host box, and the driven impeller of installing at its other end is positioned at secondary machine box.

During the utility model work, because the instant tail gas of discharging of driving engine not only carries a large amount of heat of high temperature, also the high pressure because of engine chamber is carrying enough fluid dynamic energies from exhausr port release thing, and its blade curved surface of active impeller that is placed in the exhaust pipe end hosts box begins to continue to rotate behind the application force of the tail gas continuous flow that is subjected to having fluid dynamic energy, and the driven impeller that is installed in the rotary actuator other end (mouth) is also along with the rotation synchronously of active impeller or with the cireular frequency rotation of proper proportion, because the suction surface of driven impeller is towards the air inlet openings of secondary machine box, air sucks the backheat sleeve pipe through the air inlet openings of secondary machine box endlessly, in the hot gas delivery port process of flowing of backheat sleeve pipe, contain a large amount of high temperature heat in the tail gas that is about to discharge through exhaust pipe, and the perisporium that is rich in the tail gas process exhaust pipe of high temperature heat conducts heat indirectly to being in flow air in the backheat sleeve pipe, suction air heats up through heat absorption in the way that is included in the intraluminal exhaust pipe periphery wall of backheat sleeve pipe, is about to suck the air heating in the backheat sleeve pipe; Along with flow air is heated by the periphery wall of exhaust pipe in flow process, when moving closer to the hot gas delivery port, the heat energy of its absorption is also more and more sufficient, and then supply with heating, heating system by the hot gas delivery port this moment, is used for heat supply or heating in the car.By said structure and its principle introduction as can be seen, it is heat supply in the car, heating that the utility model makes full use of the residual heat of heat energy that tail gas carries, energy-saving and cost-reducing, cost is low, economic environmental protection, gas supplied sheerly is an air in its warm braw, promptly can not pollute air in the car.
