Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blowing converter, in particular to a novel high-strength flash blowing converter reaction tower structure. BACKGROUND

[0002] In the field of modern metallurgy and non-ferrous metal refining, flash blowing converter is widely used as an efficient and energy-saving production equipment. Such blowing converter is usually equipped with a copper water jacket cooling system, which plays a core role in absorbing a large amount of heat generated inside the furnace body by circulating cooling water, thereby maintaining the stability and safe operation of the furnace body structure. The copper water jacket is designed ingeniously, which contains carefully arranged cooling water channels, and high-efficiency heat transfer is achieved through heat exchange between water flow and furnace wall.

[0003] However, in actual operation, the blowing converter usually has the highest temperature at the bottom near the reaction zone due to uneven temperature distribution, and the temperature becomes lower as it goes up, and the temperature of each layer is not constant and will change to some extent. As the amount of feed increases, the heat load of the reaction tower also increases, and the high-temperature area gradually moves down. When the amount of feed changes greatly, the temperature of the reaction tower fluctuates greatly, which has a great impact on the refractory material inside the reaction tower, so it is hoped that the reaction tower temperature under different feed amounts can be stabilized by adjusting the amount of water in the external water jacket.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0023] Referring to Figures 1-4 The figure shows a new type of high-strength flash smelting furnace reaction tower structure, which comprises a reaction tower body 1, a copper jet 4 is arranged at the top of the reaction tower body 1, the reaction tower body 1 is composed of a plurality of copper water jacket layers 2 and a cylinder body 3, the copper water jacket layer 2 comprises a plurality of copper water jacket bodies 21, the copper water jacket bodies 21 are arranged in a circumferential array, and the copper water jacket bodies 21 are provided with a water inlet pipe 22 and a water outlet pipe 23, a thermometer for detecting water temperature is arranged on the water outlet pipe 23 of the copper water jacket body 21, and further comprising:

[0024] A series number adjusting assembly 5 is arranged between two adjacent copper water jacket bodies 21, which is used for adjusting the series number of the copper water jacket bodies 21;

[0025] The bottom of the reaction tower body 1 is a reaction zone with the highest temperature, and then gradually moves away from the reaction zone upwards, and the temperature gradually decreases layer by layer. The copper water jacket layer 2 at a high position is often connected in series, and the copper water jacket body 21 is connected in series in a certain number, for example, the second layer at the bottom is connected in series by two in and one out, the second layer is connected in series by three in and one out, the third to ninth layers are connected in series by four in and one out, and so on. Thus, the flow rate of the cooling water can be changed according to the different temperatures at different heights to meet the corresponding heat exchange efficiency.

[0026] However, in actual process, the temperature in the reaction tower body 1 changes, so that the actual temperature of each layer of copper water jacket body 21 also changes. At this time, using the same water flow rate may cause local temperature of the furnace body to change suddenly, forming a significant temperature gradient, and then causing serious thermal stress problems. Therefore, the number of series connection of the copper water jacket body 21 can be adjusted by the series number adjusting assembly 5, for example, when the temperature rises, the number of series connection can be reduced, so as to increase the flow rate of the cooling water and increase the heat exchange efficiency. Similarly, when the temperature decreases, the number of series connection can be increased, so as to reduce the flow rate of the cooling water and reduce the heat exchange efficiency.

[0027] In an embodiment, the reaction tower body 1 is columnar as a whole, the tower height is 7 m, the tower body diameter is 5 m, the reaction tower body 1 is arranged axially by 18 layers of copper water jacket layers 2 and 17 layers of cylinder bodies 3, the bottom is the first layer of copper water jacket layer 2, the first layer of copper water jacket layer 2 includes 40 copper water jacket bodies 21, and the first layer of copper water jacket body 21 is a sawtooth-shaped copper-steel composite copper water jacket structure. Compared with the traditional buried pipe type copper water jacket, the internal water channel is longer, the heat exchange area is larger, and the cooling effect is better. The second layer of copper water jacket layer 2 includes 42 copper water jacket bodies 21, and each layer of the third to seventeenth layers of copper water jacket layers 2 includes 16 copper water jacket bodies 21. The second to seventeenth layers of copper water jacket bodies 21 are all buried pipe type horizontal water jackets, and the thickness of the horizontal water jackets is 76 mm. The topmost copper water jacket body 21 is a BIC water jacket with 60 blocks.

[0028] The center axial distance between the first layer of copper water jacket layer 2 and the second layer is 25 mm, the center axial distance between the second to ninth layers of copper water jacket layers 2 is 290 mm, the center axial distance between the ninth to seventeenth layers of copper water jacket layers 2 is 390 mm, and the center axial distance between the BIC water jacket and the seventeenth layer of copper water jacket layer 2 is 354 mm.

[0029] In an embodiment, the series number adjusting assembly 5 includes a first connecting valve 51 provided on the water inlet pipe 22 of the copper water jacket body 21, and a second connecting valve 52 provided on the water outlet pipe 23 of the adjacent copper water jacket body 21. The structure of the second connecting valve 52 is the same as that of the first connecting valve 51. The first connecting valve 51 is provided with a cooling water inlet 53, the second connecting valve 52 is provided with a cooling water outlet 54, and the first connecting valve 51 and the second connecting valve 52 are connected by a through pipe 55.

[0030] The initial state, such as the 3-17 layers, adopts one-in-one four copper water jacket bodies 21 connected in series, 16 in each layer, and each layer is divided into four groups at the beginning. When the temperature is detected to be reduced and the number of series needs to be changed, the series number adjusting assembly 5 on the last copper water jacket body 21 of the first group is started to connect the water outlet pipe 23 on the copper water jacket body 21 with the water inlet pipe 22 on the next copper water jacket body 21, and the rear also changes accordingly. At the same time, the last copper water jacket body 21 of each layer can also be connected up and down, and the series number adjusting assembly 5 is vertically distributed. In this way, several layers with similar temperatures can also be connected together, so that the whole becomes five series. Conversely, when the temperature is detected to be increased, the flow rate of the cooling water can also be increased by reducing the number of series.

[0031] In an embodiment, the first connecting valve 51 comprises a shell 511 connected with the water inlet pipe 22, and a rotating valve core 512 is arranged in the shell 511. An L-shaped water passage 513 is arranged in the inner cavity of the rotating valve core 512, one end of the water passage 513 is connected with the water inlet pipe 22, and the other end of the water passage 513 is connected with the cooling water inlet 53 or the through pipe 55.

[0032] When the number of series needs to be adjusted, the rotating valve core 512 inside can be rotated to change the orientation of one end of the L-shaped water passage 513, so as to realize the state of conduction or disconnection.

[0033] In an embodiment, one end of the rotating valve core 512 is provided with a driving rod 514, one end of the driving rod 514 is provided with a driving piece, a sliding groove is arranged in the shell 511, and a limiting sliding block 515 is arranged on the rotating valve core 512 and slides in the sliding groove, for limiting the rotation of the rotating valve core 512.
