The invention will be described in more detail with reference to the following examples and the accompanying drawings:

fig. 1 shows a plan layout structure of the present invention mounted on the lower part of an automobile. Parts No. 1-8 represent additional parts of the automobile, respectively. The automobile chassis comprises a frame 1, an engine 2, an air filter 3 of a carburetor, a cooling water tank 4, a steering wheel or front wheel 5, a driving wheel or rear wheel 6, a gasoline tank 7 and a storage battery 8.

Fig. 1 to 4 show the structure of the anechoic chamber and the fan of the present invention.

The air pipe 10 of the first silencing chamber 9 is communicated with an exhaust gas discharge pipe of an engine, the first silencing chamber 9 and the second silencing chamber 11 are identical in structure, radiating fins 12 are arranged on the periphery of the first silencing chamber, radiating pipes 13 extending out of the upper portion and the lower portion of the first silencing chamber are arranged in the first silencing chamber, and sound absorption nets 14 are arranged outside the radiating pipes. The center of the anechoic chamber is provided with a heat absorption pipe 15, the embodiment adopts a triangular pipe, and the periphery of the heat absorption pipe 15 is provided with an S-shaped heat absorption pipe 16. The inlet and outlet of the heat absorbing pipes 15 and 16 are respectively communicated with the adjacent parts, and the communication structure of the embodiment is as follows: the pipe orifice (containing the heat absorption pipes 15 and 16) below the second silencing chamber 11 is communicated with the outlet of the purified water tank, the pipe orifice (containing the heat absorption pipes 15 and 16) above the second silencing chamber is communicated with the pipe orifice (containing the heat absorption pipes 15 and 16) above the first silencing chamber, and the pipe orifice (containing the heat absorption pipes 15 and 16) below the first silencing chamber is communicated with the air filter 3. The first sound-deadening chamber is followed by a fan 17 to evacuate the first sound-deadening chamber and pressurize it before being pressed into the second sound-deadening chamber. The fan motor 20 may utilize the vehicle battery 8 as a power source or a battery may be added near the fan motor. The high temperature tail gas discharged by the engine passes through the turbulent flow and the heat exchange of the first and the second silencing chambers, on one hand, the temperature of the tail gas is greatly reduced, the noise of the tail gas is eliminated by the sound absorption net, and on the other hand, the gas from the purified water tank 18 is preheated and heated, which is beneficial to the work of the engine.

In order to increase the pressure of the tail gas entering the purified water tank so as to facilitate the tail gas to pass through the filtering device 24, an air compressor 19 is arranged behind the second silencing chamber, after the pressure is increased, the tail gas entering the purified water tank and the lime water are stirred and mixed, and then harmful substances in the tail gas and the lime water act to generate precipitate. The specific reaction is as follows:

lime water is evaporated into water vapor, and the water vapor entering the engine is greatly increased in temperature through preheating in the second silencing chamber and further preheating in the first silencing chamber as shown in figure 1, and the water vapor and air (about half of each) return to the air filter to form secondary combustion of tail gas, so that the purposes of purifying the tail gas and recycling the water vapor are achieved.

Fig. 5 to 7 show the structure of the purified water tank 18. The top of the purified water tank is provided with a water filling port 21, the periphery of the purified water tank is provided with radiating fins, the inside of the purified water tank is provided with a radiating pipe 13, and the outside of the radiating pipe is provided with a sound absorption net 14. The bottom of the purified water tank is provided with a water outlet pipe 22, and a liquid level indicating line 23 and a filtering device 24 are arranged on the water outlet pipe. The filtering device of the embodiment adopts the structure of fig. 6, namely, four filtering layers 25 of 10 layers of gauze, five water passing copper plates 27 with filtering holes 26, a water level line 23 on the top, and a safety valve 29 above a water storage device 28 on a water outlet pipe.

When in use, the tail gas is prepared according to the following procedures: exhaust gas-first anechoic chamber-fan-second anechoic chamber-air compressor-purified water tank-filtering device (water vapour) -second anechoic chamber-first anechoic chamber-air filter of carburetor.

The utility model discloses contrast prior art has following advantage:

the noise of the exhaust pipe can be eliminated; the tail gas can be purified; the tail gas is changed into water vapor through the purification water tank and then returns to the air filter for reuse.
