Description
Technical field
The invention belongs to blue charcoal industrial technology field, relate to a kind of quenching waste-heat recovery device, be specifically related to heat pipe quenching waste-heat recovery device in a kind of internal thermal upright carbonization furnace.
Background technology
Along with the proposition of harmonious society and the strategy of sustainable development, environmental pollution and resource clean and effective utilize and become people's first concern object.In the energy resource structure of China, coal is in occupation of leading position, and the clean and effective of coal utilizes the most important thing having become modern social development, produces significant to realizing China's high-efficient energy-saving environment friendly.Pyrolysis of coal is the basis of coal clean utilization, is the important step of the processes such as coal gasification, liquefaction, refining, can produces semicoke (also known as blue charcoal), coal tar and raw coke oven gas.
The excellent coal resources major part of China is stored in Inner Mongol, Shaanxi, Xinjiang, Gansu, Shanxi, six, Ningxia province, there are three low three high features, namely special low ash, special low-sulfur, special low-phosphorous, golf calorific value, high volatile, high chemism, be the fat coal source obtaining high-quality semicoke.For this reason, Anshan Research Inst. of Heat Energy, China Iron & Steel Group has researched and developed with the lump coal such as jet coal, the dross coal internal thermal upright formula retort that is raw material to produce blue charcoal.
The Shenfu coalfield of In Shanxi Area be distributed in Yulin Prefecture of Shaanxi Province Shenmu County, Fugu, Yulin, Hengshan Mountain, pacify the border region and the county such as deckle, city domestic, belong to the main place of production of jet coal and dross coal, the advantage that these coals have " low ash, low-sulfur, Gao Shui, golf calorific value ".All the time, Lan Tan enterprise is the pillar industry of Yulin City, in order to promote that the energy-conserving and environment-protective of Yulin periphery Lan Tan enterprise are produced, the design of Co., Ltd of metallurgical design and research institute of China National Heavy Machinery Research Institute Co., Ltd. and Shaanxi have developed SH2007 type internal thermal upright formula retort, this stove comprises preheating section, retort section and cooling section, is made up of carbonization chamber, qi-emitting hole, combustion chamber, coke discharging mouth and coke quenching pool.After coal grain enters carbonization chamber, with the inert gas flowed into from qi-emitting hole, through preheating and destructive distillation, the coal gas produced burns in a combustion chamber, semicoke then drops into coke quenching pool from coke discharging mouth, adopts water seal cooling semicoke, is then scraped by drag conveyor by semicoke.
At present, Yulin overwhelming majority Lan Tan enterprise all implements the Production Regional segmentations such as storage Jiao, coal yard, coal preparation plant and arranges, clear water quenching, water seal circulates, coke-stove gas all fully utilizes, and has taken leave of the situation that ammoniacal liquor arranges coal gas lighting outward, has effectively controlled environmental pollution.But blue charcoal still exists some pollution problems of being badly in need of solving in producing, water-cooled quenching is one of comparatively serious problem.Although the environmental pollution that water-cooled quenching can effectively prevent coal gas quenching from causing, but the quenching hot waste water of pitchy can give out a large amount of toxic and harmfuls in air.Meanwhile, when semicoke is pulled out from water, still need the heat adopting a large amount of gas-fired to produce to go to dry semicoke, this not only pollutes a large amount of water, also wastes semicoke waste heat, consumes a large amount of additional heat.
