DETAILED DESCRIPTION - Biochemical gas device system comprises a limiting volume type metering water tank provided system (1), which is fixed, and a tap water pipe (2) comprising a metering water tank cover (3), which is led into the limiting volume type metering water tank provided system. The tap water pipe is provided with a metering tap water control valve (4). The metering water tank cover is provided with a rough material inlet pipe (5). The upper end of the rough material inlet pipe is provided with a movable filter discharging pipe. The bottom of the limiting volume type water tank provided system is provided with a water tank. The water tank is provided with a metering lower water pipe. The metering lower water pipe is led into a biochemical gas reactor through a reactor sealing cover. The metering lower water pipe is provided with an automatic metering control water valve to control acid-aqueous solution. The biochemical gas reactor is designed with a conical bottom. The reactor seal cover is provided with a material inlet. The material inlet is provided with a material port sealing cover. The material port sealing cover is provided with an overpressure exhaust pipe. The overpressure exhaust tube is provided with an automatic ultra-pressure discharge valve. The overpressure exhaust tube is provided with a clean filter. The biochemical fuel gas making system of a gas delivery opening is provided with a gas pipe. The gas pipe comprises a gun type fuel gas pipe. The biochemical gas reactor is provided with a biochemical gas generating agent. The volume type metering water tank provided system is provided with the acid aqueous solution. The gas fuel is stored in the gas storage tank. The gas fuel is conveyed into an infrared non-petrochemical gas device through an infrared non-petrochemical gas supply conveying pipe. The measuring gas control valve and infrared non-petrochemical gas device are fixed with a support and a device body. The fuel gas device is provided with an electronic ignition switch. The infrared non-petrochemical gas device is provided with a high temperature refractory ceramic radiation heat cover. The infrared non-petrochemical gas device is connected with the external pipe, gas pipe and control valve.
