Problems solved by technology

[0005] The purpose of the present invention is to overcome the disadvantages of low strength of the inner cylinder body of the existing riser, the complex arrangement of the water jacket structure, the low service life, and the difficulty of manufacture, and provide a seamless coke oven riser raw gas vaporization cooling device structure and Its production method adopts the technical scheme of the present invention, and the outer wall of the inner cylinder is formed with an annular vapor-liquid groove and a vapor-liquid communication groove by a material removal process, and the annular vapor-liquid groove of the inner cylinder is surrounded by the outer cylinder to form an annular The chamber, the vapor-liquid communication groove of the inner cylinder, the outer wall of the inner cylinder and the outer cylinder form a flow equalization channel. After entering the annular chamber, the heat exchange medium is quickly distributed along the circumference of the inner cylinder and enters the annular chamber. The heat exchange medium in the chamber diffuses radially to the inner cylinder along each flow equalization channel and flows into the next annular chamber. Not only the heat exchange efficiency is high, but also the inner cylinder is integrally formed by the material removal process, and the overall strength is higher than that of the prior art. The riser heat exchanger formed by integral casting and the riser heat exchanger welded by coil plate are taller and better in pressure resistance; and the structure of the water jacket is simpler, the manufacturing method is simple, and the service life is longer

Abstract

The invention discloses a seamless coke oven ascension pipe raw gas evaporation cooling device structure, and belongs to the field of ascension pipe heat exchangers. According to the seamless coke oven ascension pipe raw gas evaporation cooling device structure, annular vapor-liquid grooves and vapor-liquid communication grooves are formed in the outer wall of an internal cylinder by using a removal material processing technology, annular chambers are defined by the annular vapor-liquid grooves of the internal cylinder and an external cylinder, and homogeneous flow channels are defined by thevapor-liquid communication grooves of the internal cylinder, the outer wall of the internal cylinder and the external cylinder. A heat transferring medium enters the annular chambers and then is quickly distributed uniformly along the circumference of the internal cylinder, and after entering an annular chamber, the heat transferring medium is radially diffused to the internal cylinder along all the homogeneous flow channels and flows into the next annular chamber. The heat transferring efficiency is high, and moreover, the internal cylinder is internally formed by using the removal material processing technology, so that compared with an ascension pipe heat exchanger in the prior art, the overall strength is higher, and the pressure bearing capacity is higher. The structure of a water jacket is simpler, the manufacturing method is simple, and the service life is longer.

Description

technical field [0001] The invention relates to a heat exchange device, more specifically, to a structure and a manufacturing method of a raw gas vaporization cooling device of a seamless coke oven rising pipe. Background technique [0002] As we all know, the temperature of the raw coal gas escaping from the rising pipe of the coke oven carbonization chamber is 650-850°C, and the heat taken out accounts for about 35% of the total heat consumption of coking. Under the conventional process, a large amount of circulating ammonia water at 70-75 °C is sprayed on the bridge pipe to reduce the temperature of the high-temperature raw gas to 95-105 °C, and then enter the recovery gas purification system, which not only consumes a large amount of ammonia water, but also increases the power consumption in the system , It also deteriorates the operating environment of the coke oven, and also leads to a lot of waste heat. For a long time, domestic and foreign researchers have done a lo...
