Abstract: An intelligent smoke exhaust improving device comprises a main body having one end configured as a connecting pipe and the other end as an exhaust outlet. A bypass apparatus is assembled between the main body and an engine through a connecting elbow unit. A microcomputer automatic control device may fully automatically control on the basis of a predetermined value of back pressure inside the main body. When the smoke particles block the ceramic filter cartridge causing the rise of the back pressure, the microcomputer automatic control device will control the bypass apparatus to open a bypass valve to discharge most of the waste gas and allow partial waste gas entering a smoke filterer for reducing the wind pressure and flow rate, so as to improve the burning time and efficiency of the smoke particles on the ceramic filtering cartridge and achieve an automatic regeneration function. When the back pressure of the device reaches the predetermined standard, the microcomputer automatic control device will control the bypass apparatus to return to the normal intake state. A cyclone mixed combustion chamber is disposed at the end of the main body near the connecting pipe. A round-hopper-shaped diversion device is disposed in front of the cyclone mixed combustion chamber, and the front end of the diversion device is a pre-combustion chamber. The pre-combustion chamber is configured with an electrically controlled oil injection plug, an gas combustion assisting pipe, and an ignition device connected to and controlled by the microcomputer automatic control device to control the automatic operations of oil injection time, temperature, back pressure, etc., and perform the power failure protection. The electrically controlled oil injection plug is an electrically controlled device capable of setting different oil injection time. The pre-combustion chamber is mainly configured to mix the engine waste smoke/gas with the atomized fuel and to ignite and burn by touching the ignition device. The engine waste smoke/gas will further pass through a plurality of oblique openings designed by a design of pi*r^2 on the round-hopper-shaped surface of the diversion device, such that the cyclone mixed smoke may generate large cyclone combustion and touch the ceramic filtering cartridge behind the cyclone mixed combustion chamber under an average temperature. The ceramic filtering cartridge may capture the smoke particles on the flow passage under the average temperature to burn once again, which is called the automatic regeneration. The time, temperature, and back pressure of the automatic regeneration can all be configured. When the regeneration time is expired, the function of the ceramic filtering cartridge for filtering the smoke is resumed. A flameproof apparatus is disposed at the rear end of the smoke filtering device. The flameproof apparatus may block the flame emitted during the re-combustion process from being directly emitted and generate a turbulent flow for noise reduction. The control system of the present invention can set up a PLC manual operation module or an APP for operation control on mobile phone or fully computer remote operation control on the cloud according to different requirements.
