つているのが現状である。 Conventional technology: Conventional gasoline engines use catalysts to purify exhaust gas, but they have no noise reduction effect and have many problems in terms of cost and longevity. In addition, the need for purifying and silencing the exhaust gas of diesel engines, which have large dust concentrations and suspended particles, is greater than that of gasoline engines, but there are many problems that are difficult to solve. There are similar problems. For this reason, many institutions emit untreated exhaust gas, causing air pollution such as photochemical smog and noise pollution, which has become a social problem. On the other hand, despite the fact that thermal energy is used in many fields such as agricultural heating, indoor heating, hot water, and hot air supply, waste heat is not recovered from exhaust gas or expensive heat exchangers are installed separately. The current situation is that the vehicles are operated uneconomically.

利用される。 When the flowing water 19 in the water pipe 14 is used in the dust collection waste heat recovery silencer S 1 for heating shown in FIG. 5, the temperature of the flowing water 19 is almost equal to the outlet temperature of the radiator attached to the engine. The temperature of the exhaust gas flowing around the outer periphery of the water pipe 14 is further increased to increase the heat quantity, and the heat quantity is reduced by being used for heating etc., and after the temperature is lowered to a temperature equivalent to the engine radiator input temperature, It is returned to the engine radiator and circulated again. On the other hand, the exhaust gas that has undergone heat exchange is either cooled to a low temperature, reduced in volume, and released into the atmosphere, or reused as a heat source for temperature or hot air.

As explained above, this idea achieves exhaust gas purification using catalysts, or dust collection and purification of exhaust gas that could not be solved with catalysts, without relying on expensive and structurally complex equipment. It has both waste heat recovery and noise reduction effect,
The exhaust gas is collected and purified by electrostatic precipitator using a high-voltage power supply (attached to the engine), and the purified exhaust gas is guided to the waste heat recovery section, which causes the adhesion of suspended matter that reduces efficiency in the heat exchange section. It changes the flow direction of the exhaust gas at the dust collection part and expands its volume, reducing exhaust noise and pressure loss.It is also lightweight, compact, and can be installed at low cost. It exhibits many features as an exhaust gas purifier, waste heat recovery, and muffler for industrial internal combustion engines. Therefore, significant effects can be expected if applied not only to land internal combustion engines but also to vehicle engines, especially diesel engines. In particular, the present invention has a cathode mechanism and an anode mechanism of the dust collector, which are connected to a linear radiation source stretched between the dust collector outer cylinder and inner cylinder dust collection electrode, and between the dust collector outer cylinder and inner cylinder dust collection electrode. Since it is formed from electrodes, the dust collection and noise silencing effect is performed effectively, and since the dust collector outer cylinder and the waste heat recovery apparatus outer cylinder are removable, internal cleaning, maintenance inspection, and repair are easy. can.
