The invention relates to a two-time condensation recovery device for waste heat of coke-oven crude gas, which mainly solves the technique problem that the prior waste-heat recovery device is easy to coke and easy to damage causing leakage during application. The recovery device comprises a crude-gas two-time condenser, three groups of built-in heat-absorbing disc box tubes and a valve component for regulating heat absorption modes, wherein two ends of the crude-gas two-time condenser are provided with a crude gas inlet and a crude gas outlet; three groups of heat-absorbing disc box tubes are arranged inside a crude-gas two-time condenser shell side by side; a water replenishment pipeline is connected with the input end of each group of heat-absorbing disc box tubes through water inlet valves respectively; a hot-water output pipeline is connected with the output end of each group of heat-absorbing disc box tubes respectively; a water outlet valves are arranged between the output ends of the first two groups of heat-absorbing disc box tubes and the hot-water output pipeline; the back end of the hot-water output pipeline is provided with a flow control valve; and communication valvesare arranged between the output end of a first group of heat-absorbing disc box tubes and the input end of a second group of heat-absorbing disc box tubes, as well as between the output end of the second group of heat-absorbing disc box tubes and the input end of a third group of heat-absorbing disc box tubes.
Description
technical field [0001] The invention relates to a cooling treatment device for raw gas by-product in the coking process of a coke oven, in particular to a recovery device for secondary condensation waste heat of raw gas in a coke oven. Background technique [0002] Energy recycling in the iron and steel industry is the main means of energy saving and emission reduction. The application of new energy recovery technologies in the current coking process has been paid more and more attention. In the traditional coking system, the raw gas coming out of the rising pipe is directly sent to the downstream spraying of ammonia water. The rapid cooling production process leads to a large amount of heat in the coke oven raw gas not being effectively recovered, resulting in energy waste and environmental pollution. [0003] In order to recover the waste heat of the raw gas in the coking process, it is necessary to overcome the problem that the tar precipitated in the rising pipe due to t...
