Description
Technical Field
The invention belongs to the field of coke oven equipment, and particularly relates to a coke oven flue waste gas waste heat recovery device with long service life.
Background
The coke oven can carry out high-temperature carbonization treatment on coal, and can efficiently convert the coal into products such as coke, coke oven gas, coal tar, crude benzene and the like, thereby being an efficient energy conversion kiln. In the heat of the coke oven expenditure, the heat of the crude gas at 650-700 ℃ is about 36%, and the recovery and utilization value is extremely high. At present, a cooling treatment process is generally adopted to realize industrial application of raw gas, and the traditional process is as follows: spraying a large amount of circulating ammonia water at 70-75 ℃ to the high-temperature raw gas to cool the high-temperature raw gas, so as to realize waste heat recovery, however, the waste of heat brought out by the high-temperature raw gas due to the large amount of evaporation of the circulating ammonia water is caused.
In the 80 s of the 20 th century, most coking plants in japan have used conduction oil for riser recovery of raw gas carry-over heat: they make the riser into a jacket pipe, and the heat transfer oil indirectly exchanges heat with the high temperature raw gas through the jacket pipe, so that the heated high temperature heat transfer oil can be used for various purposes, such as ammonia distillation, coal tar distillation, drying and charging coal, etc. Later, the economic steel in China has been subjected to similar tests on a five-hole riser; many enterprises in China such as Wu Steel, ma Steel, saddle Steel, lian Steel, beijing coking plant, shenyang gas two plant, yi-Tien-iron, pingshan coking plant and the like use a water vaporization cooling technology to recover the heat in a riser; in addition, enterprises adopt a method of indirectly exchanging heat with high-temperature raw gas by taking nitrogen as a medium.
The structure of the traditional coke oven riser raw gas waste heat recovery heat device is an overall inner, middle and outer three-layer basic structure. The inner layer is a cylinder made of high-temperature-resistant and corrosion-resistant alloy steel, and raw gas flows through the cylinder from bottom to top. The middle is a core heat transfer layer, a high-temperature resistant phase change material layer with high heat conduction capability and a certain thickness is closely attached to the outer wall of the inner cylinder, a heat transfer pipe passes through the phase change material layer and is closely contacted with the phase change material layer, a heat taking medium flows through the heat transfer pipe, the heat taking medium absorbs the heat release quantity of raw gas in the inner cylinder in the flowing process, and the temperature is increased in the flowing process from bottom to top. The heat transfer pipe or the spiral ascending spiral is arranged in the solid medium or is vertically arranged on the phase change material layer from bottom to top, and the phase change material layer needs to cover the outer surface of the whole heat transfer pipe; the outer layer is a heat preservation protective layer, the metal cylinder body is made of metal, a heat preservation material is stuck on the inner wall surface, the heat preservation and protection effects on the inner cylinder and the middle core heat transfer layer are achieved, heat loss is reduced, and the heat preservation protective layer is free from impact.
However, the prior art coke oven riser raw gas waste heat recovery heat device has more or less the following problems: the heat transfer process has unreasonable structural design, unsmooth circulation and low heat exchange efficiency, and tar adhesion on the side wall surface of raw gas causes blockage of a raw gas channel, coking of heat conduction oil causes blockage of a heat conduction oil channel, and is easy to corrode by media and the like or can not effectively solve the problems of thermal expansion and cold contraction in the starting, stopping and running processes, so that the method is difficult to implement successfully or has a satisfactory effect.
