Embodiment 1

[0034] Such as figure 2 As shown in the present invention, the figure 2 The riser heat exchanger shown in 1.

[0035] Specifically, the riser heat exchanger 1 includes an inner tube 103 and an outer tube 105 sleeved on the inner tube 103, the inner tube 103 is hollow, forming a raw gas channel 101 for the circulation of raw gas; the inner tube 103 and the outer tube A cavity 104 is formed between 105, and the cavity 104 is the water supply channel. The lower end of the cavity 104 is provided with a water inlet 107, and the upper end is provided with a steam outlet 108. The feed water enters the cavity 104 through the water inlet 107, and heat exchange through the inner tube 103 absorbs the sensible heat of the raw gas to raise the temperature. Become a steam-water mixture, and discharge from the steam outlet 108; Wherein, the water inlet 107 is also provided with a flow guide element that makes the water entering by the water inlet 107 diffuse to the circumference of the c...

Embodiment 2

[0041] Such as image 3 As shown in the present invention can also be used image 3 The riser heat exchanger 1 shown in , the riser heat exchanger 1 in this embodiment is a deformation of the riser heat exchanger in the first embodiment.

[0042] In this embodiment, the riser heat exchanger 1 includes an inner tube 110 and an outer tube 112 sleeved on the inner tube 110, a cavity 114 is formed between the inner tube 110 and the outer tube 112; the inner tube 110 and the outer tube The specific structure can refer to what is shown in the first embodiment, which is not limited here.

[0043] In this embodiment, the cavity 114 can be provided with a coil 111 spirally wound on the outer wall of the inner tube 110; the lower end of the cavity 114 is provided with a water inlet 113 communicating with the coil 111, and the upper end is provided with a The steam outlet 11 communicated with the other end of the coil pipe 111. The coiled tube 111 is wound tightly and without gaps on ...

Abstract

The invention discloses a coke oven crude gas sensible heat recycling system. The coke oven crude gas sensible heat recycling system comprises an oxygen removing device, a steam dome and one or more sets of ascending tube heat exchanger units, and each ascending tube heat exchanger unit is formed by connecting multiple ascending tube heat exchangers in parallel; supplied water is connected with the steam dome through the oxygen removing device, and the steam dome is connected with the ascending tube heat exchangers to form a steam-water loop; the supplied water is conveyed into the steam dome after oxygen in the supplied water is removed through the oxygen removing device, the supplied water in the steam dome is divided into multiple branches to flow through supplied water channels of all ascending tube heat exchangers, the supplied water in the supplied water channels is heated to form a steam-water mixture to be sent back to the steam dome, steam-water separation is conducted on the steam-water mixture in the steam dome, and separated steam is output for use. By means of coke oven crude gas sensible heat recycling system, the defect that the coke oven crude gas working environment is bad is overcome, the defects of a past coke oven crude gas sensible heat recycling technology are overcome, and the sensible heat recycling device and system which are compact in structure, good in effect, stable in operation and convenient to install are provided.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery devices, in particular to a coke oven raw gas sensible heat recovery system. Background technique [0002] During the coking process of the coke oven, a large amount of raw coal gas is produced in the carbonization chamber, which is sent to the chemical production system for purification after being cooled and collected by the coke oven riser pipe, bridge pipe, and gas collection pipe. In one coking cycle, the raw gas produced by the single-hole carbonization chamber is nearly 10,000m3 3 , when the raw gas passes through the coke oven riser, the temperature is as high as 650°C, which contains a lot of sensible heat. In order to reduce the temperature of coke oven raw gas to facilitate the subsequent coking process, the traditional process adopts the process of spraying ammonia water to cool the high-temperature raw gas, so that the temperature of the raw gas is sharply dropped to 80-8...
