Description

Technical Field

[0001] This utility model relates to the field of activated coke cooling technology, specifically to an activated coke cooling device. Background Technology

[0002] Activated coke is mainly used as an adsorbent, especially in flue gas desulfurization. In dry desulfurization processes, activated coke can adsorb not only sulfur dioxide in flue gas, but also harmful substances such as dust, dioxins, and heavy metals. In addition, activated coke can also be used as a catalyst carrier and electrode material.

[0003] Activated coke can reach temperatures of several hundred degrees Celsius after exiting the processing equipment, requiring cooling. Patent CN220413257U discloses an activated coke cooling device that uses spirally arranged heat exchange tubes on the side wall of a cooling cylinder to achieve heat exchange and cooling. However, only the parts of the heat exchange tubes in contact with the cooling cylinder achieve effective heat exchange; the areas without the cooling tubes remain at higher temperatures, resulting in uneven cooling and poor cooling effect. Utility Model Content

[0004] This invention addresses the aforementioned shortcomings of existing technologies by providing an activated coke cooling device. A first heat exchange medium is arranged on the outside of the heat exchange cylinder, enabling comprehensive heat exchange between the medium and the cylinder, resulting in more uniform heat exchange. The heat exchanger facilitates heat exchange between the heat exchange cylinder and the first heat exchange medium. The heat exchange tube is located within the first heat exchange medium, ensuring that the outer wall of the heat exchange tube can also exchange heat, thereby improving heat exchange efficiency and cooling effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An activated coke cooling device includes an inclined heat exchange cylinder with a feed bin and a discharge bin connected to its two ends. A sealing sleeve is fitted around the outside of the heat exchange cylinder. A first heat exchange medium and a heat exchanger are provided between the heat exchange cylinder and the sealing sleeve. The heat exchanger includes a liquid distribution ring and a liquid collection ring fitted around the outside of the heat exchange cylinder. Heat exchange tubes are uniformly connected between the liquid distribution ring and the liquid collection ring. The liquid distribution ring has a second inlet for introducing a second heat exchange medium, and the liquid collection ring has a second outlet for discharging the second heat exchange medium.

[0007] Preferably, the sealing sleeve has a first inlet and a first outlet on its side wall.

[0008] Preferably, the heat exchange cylinder is provided with ventilation holes at both ends.

[0009] Preferably, the heat exchange cylinder has heat exchange fins on its side wall, and the heat exchange fins are located between the heat exchange tubes.

[0010] Preferably, the first heat exchange medium and the second heat exchange medium are heat transfer oil or cooling water.

[0011] Preferably, the flow direction of the second heat exchange medium in the heat exchange tube is opposite to the transport direction of the activated coke in the cooling cylinder.

[0012] Preferably, the heat exchange tube is attached to the side wall of the heat exchange cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model sets a first heat exchange medium on the outside of the heat exchange cylinder, which can carry out comprehensive heat exchange with the heat exchange cylinder, making the heat exchange more uniform. The heat exchanger exchanges heat between the heat exchange cylinder and the first heat exchange medium. The heat exchange tube is located inside the first heat exchange medium, so that the outer wall of the heat exchange tube can also exchange heat, thereby improving the heat exchange efficiency and cooling effect.

[0015] 2. This utility model increases the heat exchange area by setting heat exchange fins on the outside of the heat exchange cylinder, and the heat exchange tubes and heat exchange fins are arranged alternately to increase the uniformity of heat exchange.

[0016] 3. This utility model uses a flowing first heat exchange medium and a second heat exchange medium to achieve dual heat exchange, thereby accelerating the heat exchange speed and effect. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1As shown, an activated coke cooling device includes an inclined heat exchange cylinder 1. A feed hopper and a discharge hopper are connected to both ends of the heat exchange cylinder 1, respectively. Both ends of the heat exchange cylinder 1 have a tapered structure and are equipped with ventilation holes 101. An exhaust fan can be installed at one end to exhaust heat from the interior of the heat exchange cylinder 1.

[0023] like Figure 2 As shown, a sealing sleeve 2 is fitted around the outside of the heat exchange cylinder 1. A first heat exchange medium 4 and a heat exchanger 3 are disposed between the heat exchange cylinder 1 and the sealing sleeve 2, as follows: Figure 3 As shown, the heat exchanger 3 includes a liquid distribution ring 305 and a liquid collection ring 302 sleeved on the outside of the heat exchange cylinder 1. A heat exchange tube 303 is uniformly connected between the liquid distribution ring 305 and the liquid collection ring 302. The heat exchange tube 303 is attached to the side wall of the heat exchange cylinder 1. The liquid distribution ring 305 is provided with a second inlet 304 for introducing the second heat exchange medium 5, and the liquid collection ring 302 is provided with a second outlet 301 for discharging the second heat exchange medium 5.

[0024] The first heat exchange medium 4 can fully wrap around the outer wall of the heat exchange cylinder 1 to achieve heat exchange and ensure the uniformity of heat exchange. The heat exchange tube 303 exchanges heat with the first heat exchange medium 4 on the one hand, and exchanges heat with the heat exchange cylinder 1 on the other hand, thus accelerating the heat exchange efficiency.

[0025] In order to improve the heat exchange rate, a first inlet 201 and a first outlet 202 are provided on the side wall of the sealing sleeve 2 to realize the flow heat exchange of the first heat exchange medium 4 and to share the heat exchange pressure of the heat exchanger 3.

[0026] Heat exchange fins 102 are provided on the side wall of the heat exchange cylinder 1 to heat the heat exchange area of ​​the heat exchange cylinder 1 and improve the heat exchange efficiency. The heat exchange fins 102 are located between the heat exchange tubes 303 to make the heat exchange more uniform and faster.

[0027] The first heat exchange medium 4 and the second heat exchange medium 5 are either heat transfer oil or cooling water. In this application, cooling water is used. Heat exchange is achieved by introducing cold water, which absorbs heat and then discharges hot water.

[0028] The first heat exchange medium 4 adopts an upward inlet and downward outlet method, and the flow direction of the second heat exchange medium 5 in the heat exchange tube 303 is opposite to the conveying direction of the activated coke in the cooling cylinder, thereby improving the heat exchange effect.
