Abstract

The invention discloses a coke oven ascension pipe heat exchanger with a spiral unloading function. The coke oven ascension pipe heat exchanger comprises a preheater, a first-section heat exchange assembly and a second-section heat exchange assembly which are arranged in an ascension pipe, wherein the preheater, the first-section heat exchange assembly and the second-section heat exchange assembly each comprise a hollow heat exchange pipe, the heat exchange pipes are spiral in the ascending pipe, and the preheater, the first-section heat exchange assembly and the second-section heat exchange assembly are sequentially arranged in the ascending pipe from bottom to top and communicate with one another. The connection point of the preheater and the first-section heat exchange assembly extends out of the ascending pipe to form a first bend, and the connection point of the first-section heat exchange assembly and the second-section heat exchange assembly also extends out of the ascending pipe to form a second bend. The technical scheme has the beneficial effects that the preheater, the first-section heat exchange assembly and the second-section heat exchange assembly which are arranged separately can absorb heat step by step, and heat concentration is reduced. In addition, by means of the spiral heat exchange pipe, thermal stress generated in the heat exchange process can be eliminated, and the whole equipment is safer.

Description

technical field [0001] The invention relates to the technical field of coke oven waste heat recovery, in particular to a coke oven riser heat exchanger with a spiral unloading function. Background technique [0002] The coke oven is a kind of equipment used to convert coal to produce coke. There is a rising pipe on the top of the coke oven to lead out the auxiliary equipment of the coke oven for the raw gas in the carbonization chamber. In order to reduce energy loss, heat recovery equipment is generally installed in the riser. However, the existing heat recovery equipment is easily deformed by heat, which affects the life of the equipment. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a coke oven riser heat exchanger with a spiral unloading function, which can effectively eliminate the thermal stress in the heat exchange process and ensure the service life of the equipment. [0004] The technical solution provi...
