Abstract

The invention relates to a grading type condensing device for coal / biomass pyrolysis equipment. The grading type condensing device comprises a falling-film type condenser and a spray type condenser which are connected in series; The main body of the falling-film type condenser is cylinder-shaped, a pyrolysis vapor inlet is arranged on one side of the upper part of the falling-film type condenser, a tube type indirect heat exchanger is arranged in the middle part of the falling-film type condenser, and a liquid storage section is arranged at the lower part of the falling-film type condenser; and an air outlet is arranged on one side of the main body above the liquid storage section, and a first-grade liquid product outlet is arranged at the bottom of the main body. The main body of the spray type condenser is cylinder-shaped, atomizing nozzles are uniformly distributed at the inner top part of the spray type condenser, a liquid storage section and a coil heat exchanger are arranged at the inner bottom part of the spray type condenser, a liquid outlet is arranged on one side of the main body of the liquid storage section, the liquid outlet is communicated with an inlet of an oil pump, and an outlet of the oil pump is communicated with a liquid inlet at the top of the main body; and an uncondensable gas outlet is arranged on one side of the main body above the liquid storage section, and a second-grade liquid product outlet is arranged at the bottom of the main body. The grading type condensing device can be used for fully condensing high-temperature pyrolysis vapor and grading pyrolysis liquid products in the condensation process.

Description

Technical field [0001] The invention belongs to the technical field of condensation processes used for pyrolysis of coal, biomass and other organic wastes, and specifically relates to a condensation device used for coal and biomass pyrolysis equipment. Background technique [0002] For the pyrolysis and liquefaction of coal, biomass and other organic wastes, the condensing device is generally required to quickly condense the high-temperature pyrolysis vapor to increase the yield of liquid products. Chinese patent 200710162077.9 discloses a condensing device used in pyrolysis liquefaction equipment. The cylindrical condenser is divided into upper, middle and lower parts. The upper part is a spray condensation section, and the top is evenly distributed with atomizing nozzles; the middle part For the falling film condensation section, a tubular indirect heat exchanger is provided; the lower part is a liquid storage section; it also includes a liquid transfer pump, a cooling tower an...
