Description

Technical Field

[0001] The present invention relates to the technical field of water circulation heat exchangers, and more particularly, to a water circulation heat exchanger in petroleum catalytic reaction production. Background Art

[0002] During the petroleum catalytic reaction process, many reactions release a large amount of heat. For example, in the exothermic reaction of catalytic cracking, the main function of the water circulation heat exchanger is to transfer this excess heat to the cooling water, and the heat is carried away through the flow of water, thereby preventing the reaction system temperature from being too high, maintaining the stability of the reaction system temperature, and optimizing the reaction efficiency. The water circulation heat exchanger is widely used in petrochemical industry, especially playing a crucial role in the thermal management of processes such as catalytic cracking, hydrocracking, and reforming.

[0003] In the existing petroleum catalytic reaction production, when the material is introduced into the heat exchange tube, the solid particles in the reactants cannot be separated, and as the heat exchange work progresses, the temperature of the material decreases, and the material may solidify in the heat exchange tube, resulting in blockage of the heat exchange tube and affecting the normal use of the heat exchanger.

[0046] In a preferred embodiment, during use, the hot water after heat exchange enters the water purification tank 1001, and the scale in the hot water is filtered by the arc-shaped filter plate 1004, facilitating the subsequent recycling of the hot water.

[0047] Specifically, the working principle of this water circulation heat exchanger in petroleum catalytic reaction production is as follows: During use, the material is introduced into the separation cylinder 801 through the liquid inlet pipe 802. The solid particles in the material can be separated by the separation cover 803. The separated material enters the heat exchange tube 6 for heat exchange and cooling. The first rotating shaft 804 is driven to rotate by the double-shaft motor 805, driving the scraper 806 to rotate, pushing the solid particles on the inner wall of the separation cover 803 towards the inner cavity of the separation cover 803, and the solid particles are synchronously ground and broken by the grinding roller 807 to prevent the heat exchange tube 6 from being blocked. Moreover, when the first rotating shaft 804 rotates, the convex block 818 rotates synchronously, and under the action of the spring 816, the first connecting rod 813 is driven to reciprocate up and down. When the first connecting rod 813 moves upward, the second piston 815 disengages from the inner cavity of the filling cylinder 811, and the anticoagulant enters the inner cavity of the filling cylinder 811. When the first connecting rod 813 moves downward, the first piston 814 disengages from the inner cavity of the filling cylinder 811, injecting the anticoagulant into the liquid inlet pipe 802 to be mixed with the material, preventing the material from blocking the heat exchange tube 6 due to cooling and solidification.

[0048] When the first rotating shaft 804 rotates, the swing arm 906 and the first eccentric shaft 907 rotate synchronously, thereby driving the first driving frame 905 to drive the third piston 902 to reciprocate in the air injection tank 901. The first one-way valve 908 and the second one-way valve 909 are alternately conducted to inject air into the air duct 910 and spray it into the material through the air holes 911 to aerate the material, increasing the fluidity of the material and reducing its viscosity, thereby preventing the material from blocking the heat exchange tube 6. At the same time, the anticoagulant is further mixed into the material to improve the mixing effect of the anticoagulant.

[0049] The hot water after heat exchange enters the water purification tank 1001, and the scale in the hot water is filtered by the arc-shaped filter plate 1004 to facilitate the subsequent recycling of the hot water. Moreover, the second rotating shaft 1003 can be synchronously driven to rotate by the double-shaft motor 805, and the arc-shaped filter plate 1004 is cleaned by the brush plate 1005. At the same time, when the second rotating shaft 1003 rotates, the fourth rotating shaft 1012 is driven to rotate synchronously through the fourth gear 1016 and the third gear 1015, and the arc-shaped driving ring 1009 is driven to reciprocate by the second eccentric shaft 1014, so that the second gear 1008 is driven to rotate reciprocally through the toothed plate 1011, driving the spoiler blade 1007 to rotate synchronously, increasing the fluidity of the water and improving the heat exchange efficiency.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
