Description

Technical Field

[0001] This invention relates to the field of regeneration tower technology, and more particularly to a foam collection device for a regeneration tower. Background Technology

[0002] In the coking industry, wet oxidation generally uses air oxidation to desulfurize rich liquor. After oxidation, the rich liquor, which absorbs hydrogen sulfide, reacts to generate elemental sulfur, while the lean liquor is sent back to the desulfurization tower to continue the absorption reaction. The regeneration tower is one of the main pieces of equipment in the oxidation method for desulfurization and decyanation, used to oxidize and regenerate the desulfurization and decyanation solution. Most regeneration towers are cylindrical empty towers.

[0003] Currently, foam collection devices for regeneration towers are typically located outside the regeneration tower, using an expanded annular foam collection device installed on the outside of the tower. Existing foam collection devices for regeneration towers have at least the following defects and shortcomings: sulfur foam flows into the external foam collection device along the outer wall of the regeneration tower, the channel is short, sulfur foam in the center of the tower does not easily flow out, and the cost is high. Summary of the Invention

Example

[0025] like Figure 1-4 As shown, a foam collection device for a regeneration tower is installed inside the regeneration tower and includes a first collection tank, a second collection tank, a foam outlet, and a cleaning liquid outlet.

[0026] The second collection tank includes a conical section 7 and a cylindrical body 6. The cylindrical body 6 is a cylinder with a vertical centerline, located at the center of the regeneration tower, and its centerline is the same as the centerline of the regeneration tower. The conical section 7 is a conical cylinder, which is fixed to the bottom of the cylindrical body 6.

[0027] The first collection trough is composed of vertical plate 1, horizontal plate 2, and pad plate 5. Vertical plate 1 is horizontal at the top and curved at the bottom, providing good stress distribution and saving materials. Horizontal plate 2 is a flat plate, with vertical plate 1 welded to both sides during installation. Pad plate 5 is welded to the sides of tower wall 12. The left ends of horizontal plate 2 and vertical plate 1 are welded to pad plate 5, and the right ends of horizontal plate 2 and vertical plate 1 are welded to the outer wall of cylinder 6. Horizontal plate 2 is at its highest point on tower wall 12, gradually sloping downwards towards the center of the regeneration tower, while the lowest point is at cylinder 6, facilitating the flow of sulfur foam towards the center. The number of first collection troughs is determined based on the diameter of the regeneration tower.

[0028] The top of the cylinder 6 has an opening 13, the width of which is the same as the width of the horizontal plate 2, and the height of which corresponds to the height of the horizontal plate 2 and the bottom of the horizontal plate. The top surface of the vertical plate 1 is at the same elevation as the top surface of the cylinder 6, that is, the top surface of the vertical plate 1 and the top surface of the cylinder 6 are on the same plane.

[0029] In this embodiment, there are four first collection slots, which are evenly distributed around the circumference and welded to the outer wall of the cylinder 6.

[0030] The foam discharge outlet includes a vertical pipe 8, an elbow 9, a horizontal pipe 10, and a flange 11. The vertical pipe 8 and the horizontal pipe 10 are seamless steel pipes. The top of the vertical pipe 8 is welded to the bottom of the conical section 7, and the bottom of the vertical pipe 8 is welded to one end of the elbow 9. The other end of the elbow 9 is connected to the left end of the horizontal pipe 10. The right end of the horizontal pipe 10 extends out of the regeneration tower wall 12, and the flange 11 is welded to the right end of the horizontal pipe 10.

[0031] The cleaning fluid inlet includes a cleaning fluid pipe 4 and a cleaning fluid flange 3. The cleaning fluid pipe 4 is connected to the regeneration tower wall 12 and is located at the first collection tank, above the end of the horizontal plate 2 tower wall 12.

[0032] The number of cleaning fluid inlets is the same as the number of first collection tanks, and they correspond one-to-one, with one first collection tank corresponding to one cleaning fluid inlet.

[0033] In this embodiment, the sulfur foam after desulfurization liquid regeneration floats upwards to the top of the liquid surface at the top of the equipment. Controlled by the liquid level regulator, the clear liquid at the bottom returns to the desulfurization tower for further desulfurization. The sulfur foam is controlled on the upper surfaces of the vertical plate 1 and the cylinder 6. The sulfur foam enters the first and second collection tanks along the upper surfaces. The sulfur foam entering the first collection tank flows downwards along the horizontal plate 2 into the second collection tank, then into the sulfur foam discharge port, and finally into the foam tank along the sulfur foam discharge pipe. Through the top sight glass 14, when the sulfur foam has poor flowability and becomes clogged, the cleaning liquid valve is opened promptly to clean the sulfur foam. Each first collection tank corresponds to one cleaning liquid port to ensure timely discharge of sulfur foam.

[0034] In this invention, multiple first collection tanks are arranged radially at the top of the central cylinder of the regeneration tower. The first collection tanks are distributed along the center, and the sulfur foam collection channel is long, which is beneficial for collecting internal sulfur foam.

[0035] The present invention is provided with a cleaning liquid outlet, the number of which is the same as the number of first collection tanks, and they correspond one-to-one. Each first collection tank corresponds to one cleaning liquid outlet, which makes it easy to clean sulfur foam.

[0036] The top of the upright plate 1 of this invention is horizontal and the bottom is arc-shaped, which provides good stress distribution and saves materials.

[0037] This invention collects sulfur foam inside a tower, with a long channel, allowing sulfur foam to easily flow out from the center of the tower, and at a low cost.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
