Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust-containing steam treatment of a slag pool, and in particular to a high-temperature dust-containing steam collection device. BACKGROUND

[0002] In the steel production process, the treatment of steel slag is an important link. In order to improve the treatment efficiency and reduce environmental pollution, the process of ground slag pit for treating steel slag has been widely applied. The process mainly seals the slag pool through slag cover and water seal groove to ensure that the dust-containing steam generated during the treatment of steel slag is effectively collected and treated.

[0003] In terms of steam collection and treatment, the prior art collects steam through the exhaust port reserved on the slag cover and introduces the steam into the pipeline through the rotary sealing device to be treated in the dust collector. However, the condensed steam is prone to water leakage at the rotary sealing device, which affects the normal operation of the equipment and worsens the on-site environment. In addition, during the process of loading and discharging slag, the water seal groove is often blocked, resulting in a failure of the sealing effect and causing the dust-containing steam to overflow into the production environment, which poses a threat to the health of the operators. CONTENT OF THE UTILITY MODEL

[0004] The embodiment of the present application provides a high-temperature dust-containing steam collection device to solve the problems raised in the background art.

[0005] The embodiment of the present application provides a high-temperature dust-containing steam collection device, which comprises a slag cover, a closing piece, a steam collecting square box, a dust removal pipeline, a dust removal fan and a plurality of connecting pipes. The closing piece is installed at the opening of the slag pool, and a through hole is arranged on the side of the closing piece away from the slag pool. The projection area of the through hole on the horizontal plane is smaller than the projection area of the opening of the slag pool on the horizontal plane. The slag cover is rotationally connected to the closing piece to open and close the through hole. The sidewall of the slag pool is provided with a plurality of steam discharge ports along the length direction thereof. The steam discharge ports are close to the closing piece. The steam collecting square box is installed on the ground close to the slag pool, and the sidewall thereof is provided with a plurality of connecting holes corresponding to the steam discharge ports. The bottom of the connecting hole is flush with the bottom plane inside the steam collecting square box. The two ends of the plurality of connecting pipes are respectively inclinedly connected to the corresponding connecting holes and steam discharge ports. The dust removal pipeline is connected to the other side of the steam collecting square box away from the steam discharge ports and is provided with a valve. The dust removal fan is connected to the end of the dust removal pipeline away from the steam collecting square box.

[0006] In a possible implementation manner, the high-temperature dust-containing steam collection device further comprises a handle. The handle is arranged on the side of the slag cover away from the slag pool.

[0007] In a possible implementation, the high-temperature dust-containing steam collecting device further comprises a plurality of pressure relief covers; the slag cover is provided with a plurality of pressure relief holes; and the plurality of pressure relief covers are hinged to one side of the slag cover away from the slag pool to cover the corresponding pressure relief holes.

[0008] In a possible implementation, the steam outlet is provided with two.

[0009] In a possible implementation, the high-temperature dust-containing steam collecting device further comprises a controller; the valve is an electric valve; and the controller is electrically connected to the electric valve and the dust removal fan.

[0010] In a possible implementation, the through hole and the slag cover are square structures.

[0011] The one or more technical solutions provided in the embodiments of the present application have at least the following technical effects:

[0012] The high-temperature dust-containing steam collecting device provided by the embodiments of the present application comprises a slag cover, a closing piece, a steam collecting square box, a dust removal pipeline, a dust removal fan and a plurality of connecting pipes. After starting the slag smothering operation, the steel slag in the slag pool will produce a large amount of high-temperature water vapor containing dust when meeting water. At this time, by timely opening the valve on the dust removal pipeline and starting the dust removal fan, a micro-negative pressure working environment can be created inside the slag pool. This negative pressure state effectively promotes the water vapor to enter the steam collecting square box through the specially designed steam outlet, and then be guided to the subsequent processing process through the dust removal pipeline.

[0013] When the water vapor enters the steam collecting square box, the water vapor will quickly condense into water due to the rapid drop in the internal temperature. Thanks to the inclined design of the connecting pipes and the completely closed characteristics of the steam collecting square box, the condensed water can smoothly flow back to the slag pool through the steam outlet, thereby effectively avoiding the disorderly flow of the condensed water and the possible pollution. The closing piece at the top of the slag pool is particularly ingenious. In the process of steam rising, the closing piece can form a certain blockage and guidance to the steam, so that the water vapor has a tendency to roll downward, further enhancing the negative pressure effect in the slag pool. At the same time, the external air will naturally flow into the slag pool through the gap around the slag cover under the attraction of the negative pressure, thereby effectively solving the problem of water vapor overflow. In addition, the present application also cancels the traditional rotary seal and water seal groove structures, which not only simplifies the structure of the whole device, but also fundamentally solves the potential problems of water leakage and steam overflow caused by the damage of the rotary seal and water seal groove, further improving the stability and reliability of the whole system.

The terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. In addition, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or the communication between two elements inside. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0020] The embodiments of the present application provide a high-temperature dust-containing steam collecting device, which comprises a steam collecting box, a slag cover, a dust removal pipeline and a connection pipe. Figs. 1-2The high-temperature dust-containing steam collecting device includes a slag cover 1, a closing member 2, a steam collecting square box 3, a dust removal pipeline 4, a dust removal fan, and a plurality of connecting pipes 5. The closing member 2 is installed at the opening of the slag pool 6, and a through hole 21 is arranged on the side of the closing member 2 away from the slag pool 6. The projection area of the through hole 21 on the horizontal plane is smaller than the projection area of the opening of the slag pool 6 on the horizontal plane, that is, the cross-sectional area of the through hole 21 is smaller than the cross-sectional area of the opening of the slag pool 6. The slag cover 1 of the present application matches the through hole 21, that is, the cross-sectional area of the slag cover 1 is smaller than the cross-sectional area of the opening of the slag pool 6. The slag cover 1 is rotationally connected to the closing member 2 for opening and closing the through hole 21.

[0021] In the prior art, the slag cover 1 matches the opening of the slag pool 6, which causes a series of technical problems. First, the large volume of the slag cover 1 puts higher requirements on the selection of the matching equipment, increasing the cost of the equipment. Second, the height of the slag cover 1 when it is opened is too high, so that the installation position of the dust hood has to be correspondingly increased, which seriously affects the dust collection effect during the processes of charging and discharging the slag. In view of the above problems, the present application adopts an innovative design of the closing member 2, which significantly reduces the cross-sectional area of the slag cover 1. This design brings many advantages: it reduces the specification requirements of the matching equipment, effectively saving the cost of the equipment; the height of the slag cover 1 when it is opened is significantly reduced, which is convenient for operation and maintenance; the installation position of the dust hood can be correspondingly lowered, so that the dust is more easily introduced into the effective working area of the dust hood, significantly improving the dust removal efficiency.

[0022] The side wall of the slag pool 6 is provided with a plurality of steam discharge ports 61 along the length direction thereof. The steam discharge ports 61 are close to the closing member 2. The steam collecting square box 3 is installed on the ground close to the slag pool 6, and the side wall thereof is provided with a plurality of connecting holes corresponding to the steam discharge ports 61.

[0023] Specifically, in order to optimize the steam collecting effect, the steam collecting square box 3 can be installed on the ground through a support, or the thickness of the bottom wall of the steam collecting square box 3 is appropriately increased to ensure that the bottom inside the steam collecting square box 3 is higher than the steam discharge ports 61.

[0024] The bottom of the connecting hole is flush with the bottom plane inside the steam collecting square box 3. The two ends of the plurality of connecting pipes 5 are respectively inclinedly connected to the corresponding connecting holes and steam discharge ports 61, facilitating the entry of the condensed water into the slag pool 6. The dust removal pipeline 4 is communicated to the other side of the steam collecting square box 3 away from the steam discharge ports 61, and is provided with a valve 7. The dust removal fan is connected to the end of the dust removal pipeline 4 away from the steam collecting square box 3.

[0025] Specifically, the winch support 10 is installed on the ground, and the steam collecting square box 3 is located between the closing member 2 and the winch support 10 to ensure the compactness and stability of the entire device.

[0026] Further, the slag pool 6 of the present application partially protrudes from the ground, and the steam discharge ports 61 are also located above the ground to facilitate the connection with the connecting pipes 5.

[0027] It should be noted that after the start of the slagging operation, the steel slag in the slag pool 6 will quickly produce a large amount of high-temperature water vapor containing dust when it meets water. At this time, by timely opening the valve 7 on the dust removal pipeline 4 and starting the dust removal fan, a micro-negative pressure working environment can be created inside the slag pool 6. This negative pressure state effectively promotes the water vapor to enter the steam collecting box 3 through the specially designed steam exhaust port 61, and then be guided to the subsequent processing flow through the dust removal pipeline 4.

[0028] When the water vapor enters the steam collecting box 3, it will quickly condense into water due to the rapid drop in temperature inside. Thanks to the inclined design of the connecting pipe 5 and the completely closed nature of the steam collecting box 3, the condensed water can smoothly flow back to the slag pool 6 through the steam exhaust port 61, effectively avoiding the disorderly flow and possible pollution of the condensed water. The closure 2 at the top of the slag pool 6 is particularly ingenious. During the steam rising process, the closure 2 can form a certain blockage and guidance to it, making the water vapor have a tendency to roll downward, further enhancing the negative pressure effect inside the slag pool 6. At the same time, under the attraction of negative pressure, external air will naturally flow into the slag pool 6 through the gap around the slag cover 1, effectively solving the problem of water vapor overflow. In addition, the present application also cancels the traditional rotary seal and water seal groove structure, which not only simplifies the composition of the overall device, but also fundamentally solves the potential problems of water leakage and steam overflow caused by damage to the rotary seal and water seal groove, further improving the stability and reliability of the entire system.

[0029] In the prior art, water vapor after condensation is prone to water leakage at the rotary seal device, causing environmental deterioration. The present application effectively solves the problem of water leakage at the rotary seal by canceling the rotary seal device. In the present application, the steam collecting box 3 is designed to directly introduce the condensed water into the slag pool 6 through the steam exhaust port 61, thereby avoiding the environmental problems caused by water leakage.

[0030] In the embodiment of the present application, the high-temperature dust-containing steam collecting device further comprises a handle. The handle is arranged on the side of the slag cover 1 away from the slag pool 6.

[0031] It should be noted that the handle facilitates the operation of the hoist on the slag cover 1.

[0032] In the embodiment of the present application, the high-temperature dust-containing steam collecting device further comprises a plurality of pressure relief covers 8. The slag cover 1 is provided with a plurality of pressure relief holes 9. The plurality of pressure relief covers 8 are hinged to the side of the slag cover 1 away from the slag pool 6, and are used to cover the corresponding pressure relief holes 9.

[0033] It should be noted that during the operation of the high-temperature dust-containing steam collecting device, if the internal pressure abnormally rises, the pressure relief holes 9 can timely release the excessively high pressure to prevent safety accidents such as rupture or explosion of the device due to excessively high pressure.

[0034] In the embodiments of the present application, two steam discharge ports 61 are arranged. Of course, the present application is not limited to two steam discharge ports 61, and three or four steam discharge ports 61 can also be arranged.

[0035] In the embodiments of the present application, the high-temperature dust-containing steam collecting device further comprises a controller. The valve 7 is an electric valve. The controller is electrically connected to the electric valve and the dust removal fan.

[0036] In the embodiments of the present application, the electric connection of the controller with the electric valve and the dust removal fan enables the operator to remotely control the on-off state of the electric valve and the dust removal fan by sending instructions through the controller from a position far away from the device site. This not only improves the convenience of operation, but also reduces the number of times that the operator enters the dangerous environment of high temperature and dust, thereby reducing the safety risk.

[0037] In the embodiments of the present application, the through hole 21 and the slag cover 1 are both square structures. The cooperation between the square slag cover 1 and the through hole 21 is more compact, and it is easier to achieve a good sealing effect, which helps to prevent steam and dust from leaking out of the gap between the slag cover 1 and the through hole 21, and ensures that the collecting device can effectively collect and process steam and dust.

[0038] The various embodiments in the specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment mainly describes the differences from other embodiments.

[0039] The above embodiments are only used to illustrate the technical solutions of the present application, and are not limited to the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to some or all of the technical features. The modification or replacement does not make the essence of the corresponding technical solution deviate from the scope of the technical solutions of the present application.
