Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of water cooling jacket, especially relates to a high temperature calcined coke water cooling jacket structure of preventing oxygen corrosion. BACKGROUND

[0002] At present, in carbon technology, petroleum coke or pitch coke and the like are calcined at high temperature, and the high-temperature calcined coke at about 1000 DEG C falls into a water jacket type cooler under the action of gravity and is cooled to about 100 DEG C (to prevent oxidation of the calcined coke and ensure quality, this temperature must be ensured). Cold water enters the water jacket, and cooling of the calcined coke is carried out by a baffle between the cold water and the calcined coke. The cold water becomes hot water, is cooled by an external cooling tower to become cold water, and is driven by a circulating pump to enter the water jacket type cooler again. The water jacket type cooler is divided into high-temperature and low-temperature two sections, the two sections are connected in series through flanges, and the cooling water is connected in series through connecting pipes. The high-temperature section is at the top, and the low-temperature section is at the bottom. The high-temperature calcined coke first enters the high-temperature section and then enters the low-temperature section. The cooling water first enters the low-temperature section and then enters the high-temperature section.

[0003] Because the quality of the circulating water is poor, dirt is easily deposited, even if a hand hole is provided, the dirt cannot be discharged in time, the cooling capacity of the water cooling jacket is reduced, and at the same time, the water jacket has water flow dead angles, so that the cooling water is often retained and becomes steam, the cooling capacity is also reduced, and the wall plate of the jacket is damaged due to bulging. Oxygen dissolved in the water is precipitated at high temperature, causing oxygen corrosion of the top end of the wall plate. In addition, the heat of the high-temperature calcined coke is wasted.

[0016] The utility model will be further described below in combination with the drawings.

[0017] In the description of the utility model, it should be understood that if the positions or location relationships indicated by the terms "upper", "lower", "left", "right", "top", "bottom", "inner", "outer" and the like are based on the positions or location relationships shown in the drawings, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated devices or elements must have a particular orientation, be constructed and operated in a particular orientation, therefore, the terms describing the position relationship in the drawings are only used for exemplary description, and cannot be understood as a limitation on the patent.

[0018] Example 1

[0019] A high-temperature calcined coke water cooling jacket structure for preventing oxygen corrosion, as shown in Figure 1 and Figure 2 , comprises a cylinder 1, a water jacket 2 and a baffle 3.

[0020] The water jacket 2 is wrapped outside the cylinder 1, and the inner wall of the cylinder 1 is connected with straight fins 101 which are evenly distributed on the inner wall of the cylinder 1 and can strengthen the cooling of the high-temperature calcined coke.

[0021] The lower end side wall of the water jacket 2 is provided with a cooling water inlet 201, and the upper end side wall is provided with a cooling water outlet 202.

[0022] As a specific design, the distance between the partition plate 3 and the top of the water jacket 2 should be as small as possible; as a preferred solution, the distance between the partition plate 3 and the top of the water jacket 2 is equal to the inner diameter of the cooling water outlet 202, that is, only a distance of the inner diameter of the water outlet is left. The distance between the through hole 301 and the cooling water outlet 202 is as far as possible, and as a preferred solution, the straight line distance between the two is the farthest distance that can be set.

[0023] The working process and principle of the water cooling jacket structure of the utility model are as follows:

[0024] The cooling water is introduced into the water jacket 2 from the cooling water inlet 201, and the high-temperature calcined coke falls into the cylinder 1 from the opening above the cylinder 1, exchanges heat with the cooling water in the water jacket 2 during the falling process, and is discharged from the opening below the cylinder 1 after being cooled. Due to the arrangement of the partition plate 3 and the through hole 301, the water flow in the space below the partition plate 3 enters the space above the partition plate 3 at a flow rate much greater than that of the lower part, and flows on both sides at a relatively large flow rate, and finally flows to the outside of the water jacket 2 through the cooling water outlet 202 at a relatively large flow rate. The high-speed water flow can carry out the retained steam and the oxygen separated out from the water outside the jacket, avoids oxygen corrosion, improves the cooling capacity, and prolongs the service life of the water jacket.

[0025] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
