Abstract
The invention relates to a water cycle energy-saving muffler which uses the waste gas to heat, belonging to the mechanical production. It comprises a surface heat exchanger, a water inlet, a water outlet, a heater and a muffler. Wherein, the surface heat exchanger is connected to the muffler as a whole; the heat exchanger covers the muffler; the waste gas and the cycle water which are not contacted are used to process reflux heat exchange; the water inlet and the water outlet of heat emitter are connected via the surface heat exchanger; and the water outlet is connected to the water inlet of heater. The invention can fully utilize the waste heat of waste gas discharged by the heater to preheat the water of heater to improve the utilization of fuel heat energy; and it can reduce the discharge noise and discharge temperature to improve the economic benefits more than 5%. And the discharge noise is reduced more than 1dB based on former muffler.
Description
Technical field
The invention belongs to mechanical manufacturing field, particularly relate to a kind of water cycle energy-saving muffler with the waste gas heating.
Technical background
Fuel heater be exactly under low temperature environment by fuel consumption or natural gas for automobile and other equipment provide the independent heater of heat, adopt water as heat carrier usually.This heater can guarantee driver and conductor's ride comfort, has become the important subsystem of Hyundai Motor, and the application on Hyundai Motor more and more widely.In addition, fuel heater can be used as auxiliary heater and is used for yacht or baby plane or the like.Energy savings, reduction noise are two important performance indexes of heater.Usually the delivery temperature of fuel heater is 200 ℃～350 ℃, and obviously higher row's temperature is not fully used the heat energy of fuel.Therefore improve the utilization rate of fuel thermal energy, and further reduce exhaust noise and just seem particularly important.The silencer of fuel heater use at present is only as the usefulness that reduces exhaust noise, and a large amount of high-temp waste gas directly enters atmosphere without any utilization.
Summary of the invention
At the deficiencies in the prior art, the invention provides and a kind ofly change energy-saving muffler into surface-type heat exchanger function by silencer (or blast pipe) with fuel heater, thereby the waste heat that makes full use of the heater combustion gas carries out preheating to the heat carrier water of heater, to improve the utilization rate of fuel thermal energy; Simultaneously in this energy-saving muffler, because glassware for drinking water has the vibration-absorbing denoising effect, so this silencer also has a kind of water cycle energy-saving muffler with the waste gas heating of the effect of further reduction heater exhaust noise.
The objective of the invention is to be achieved through the following technical solutions: a kind of water cycle energy-saving muffler with the waste gas heating, form by surface-type heat exchanger, water inlet, delivery port, heater and silencer, surface-type heat exchanger and silencer suit are combined into one, heat exchanger wraps in the periphery of silencer, and non-touching waste gas and recirculated water carry out countercurrent flow.
Described silencer water inlet links to each other through surface-type heat exchanger with the delivery port of heat abstractor, and its delivery port links to each other with the water inlet of heater.
The course of work of the present invention is: with the heater blast pipe energy-saving muffler arrival end is connected with the exhaust outlet of heater, the installation situation that the port of export of silencer can directly lead to atmosphere or look concrete use equipment connects with the prolongation tail pipe; The water inlet of heat exchanger connects with the delivery port of heat abstractor, and the delivery port of heat exchanger is connected with the heater water inlet.During heater work, under the effect of heater water pump, the heat carrier water of energy-saving and noise-reducing silencer of flowing through absorbs the waste heat of heater combustion gas, reduce delivery temperature, improve the temperature at heater water inlet place, owing to the absorbing effect of water, can reach the raising fuel availability simultaneously, the purpose of energy savings and reduction heater exhaust noise.Heat abstractor generally adopts heat exchanger, and its main effect is that the heat that will pass through the water of heater heating is discharged in the specific space, as, car occupant compartment, open-air tent or the like.
Use the present invention can make full use of the heater combustion gas energy, and can reduce exhaust noise better.Empirical tests: reduced the delivery temperature of heater, can improve economy more than 5%, made exhaust noise on the basis of original muffler, further reduce by 1 of noise more than the decibel simultaneously.

Accompanying drawing is a structural representation of the present invention.
Among the figure, 1, fuel heater water inlet, 2, fuel heater, 3, the fuel heater blast pipe, 4, fuel heater delivery port, 5, heat exchanger water inlet, 6, radiator, 7, waste gas outlet, 8, silencer, 9, heat exchanger delivery port, 10, surface-type heat exchanger, 11, fuel heater combustion air inlet.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated:
Embodiment: structure as shown in drawings, form by surface-type heat exchanger 10, heat exchanger water inlet 5, fuel heater delivery port 4, fuel heater 2 and silencer 8, surface-type heat exchanger 10 is combined into one with silencer 8 suits, heat exchanger 6 wraps in the periphery of silencer 8, and non-touching waste gas and recirculated water carry out countercurrent flow; Heat exchanger water inlet 5 links to each other through surface-type heat exchanger 10 with the delivery port 9 of radiator 6, and its delivery port links to each other with the water inlet 5 of heater.
Among Fig. 1, adopt the act as a fuel heat carrier of heater 2 of water, specific implementation method is: energy-saving muffler 8 of the present invention is linked to each other with the exhaust outlet of heater with blast pipe 3,200 ℃～350 ℃ the energy-saving muffler 8 of heater combustion gas through having heat exchange and noise elimination function absorbed heat enter atmosphere behind the noise reductions.Heat exchanger water inlet 5 links to each other with the delivery port of heat abstractor, and heat exchanger delivery port 9 links to each other with the water inlet 1 of heater, and the delivery port 4 and the heat abstractor 6 of heater couple together.So just constituted a heat circulating system with energy-saving and noise-reducing effect.
Between surface-type heat exchanger 10 and silencer 8 and the heater 2, all adopt pipeline to be connected between heater 2 and heat abstractor 6 and the surface-type heat exchanger 10, the metal shell of surface-type heat exchanger 10 adopts welding to make.
In above heat circulating system, surface-type heat exchanger 10 is combined as energy-saving muffler among the present invention with silencer 8 suits, and its heat exchanger wraps in the periphery of muffler.Enter heater again after the required energy-saving muffler preheating of heat carrier water in the present invention of heater, reduced the delivery temperature of heater like this, can improve economy more than 5%, make exhaust noise on the basis of original muffler, further reduce by 1 of noise more than the decibel simultaneously.
