High-temperature physical carbonization method of carbide furnace and wood

The invention provides a high-temperature physical carbonization method of a carbonization furnace and wood. The carbide furnace comprises a horizontal carbonization tank, wherein one end of the horizontal carbonization tank is provided with an end socket, the other end of the horizontal carbonization tank is provided with a tank cover, the periphery in the carbonization tank is provided with a heat-conducting pipe through which heat-conducting media flow, the heat-conducting pipe is communicated with a heat-conducting oil feeding device arranged outside, and the heat-conducting oil feeding device is composed of a heat-conducting oil pump and a heat-conducting oil heater; the middle of the carbonization tank is provided with a lace bar frame used for containing the wood; a vacuum pumping machine connected with the carbonization tank through a vacuum pumping pipe is arranged outside the carbonization tank; the carbonization tank is connected with an external steam generating and feeding device through a steam connection pipe; the carbonization tank is further provided with a safe valve, a pressure gage and a wood still gas releasing pipe with a switch valve. The high-temperature physical carbonization method comprises the steps that (a) the wood is placed in the furnace; (b) a steam valve is opened for humidification; (c) vacuum pumping and drying are conducted; (d) temperature is increased and carbonization is conducted; (e) carbonized wood is manufactured after the temperature is decreased and preserving is conducted. The high-temperature physical carbonization method has the advantages that the used carbonization furnace is simple in structure, safe to operate and use, and convenient and reliable to use, the carbonization process is simple, the carbonization effect is good, and a use range of the carbonized wood is enlarged.

Method for adjusting an internal combustion engine with exhaust gas recirculation and device for carrying out said method

The invention relates to a method for adjusting a device (1) which essentially consists of a Lambda-1 internal combustion engine (2), a fuel induction line (3), a supplemental unit (9) arranged in the induction line (3) for compressing an air-fuel mixture required for combustion, a catalytic converter (12) arranged in the exhaust gas flow, and an exhaust gas recirculation line (15) which is disposed downstream from the catalytic converter (12), leading into the fuel induction line (3) and which is used to supply cooled exhaust gas to the air-fuel mixture. The inventive method is especially characterized in that the amount of exhaust gas which is to be supplied to the air-fuel mixture per time unit is adjusted according to the combustion chamber temperature measured in the combustion chamber of the internal combustion engine (2) in conjunction with the lambda adjustment. Preferably, said combustion chamber temperature and the amount of exhaust gas to be supplied to the air-fuel mixture per unit of time are measured and adjusted continuously. Especially when the so-called problem gases are used, the useful life of this probe becomes substantially shortened and this, in its turn, leads to high maintenance costs.

Measuring method for establishing equipment installation reference in stack pits

The invention discloses a measuring method for establishing the equipment installation reference in stack pits. The method uses a measuring system consisting of an optical cultellation instrument, a precise level instrument and two precise electronic transit instruments for completing the transfer of the equipment installation reference of pack containers and the like. The method comprises the following steps: precisely transferring the stack pit center reference point O and the north direction N reference point to corresponding visible positions on the ground; establishing reference marking points in three orientations of the east direction E, the south direction S and the west direction W on the stack pit; forming a high-precision measurement level reference plane; transferring the orientation reference marking points to proper positions at the upper end of the stack pits; and confirming the equipment installation reference elevation points on hall wall surfaces. The invention uses the measurement technical method of an electronic transit instrument industrial measuring system, ensures the stack container equipment installation precision, and avoids the error installation caused by overlarge installation reference errors, so the stack container equipment installation quality is ensured, and in addition, the safer effect can be obtained.
