Description

Technical Field

[0001] The utility model relates to a regeneration tower, in particular to an integrated flow-dividing structure at the top of the regeneration tower. Background Art

[0002] At present, the overflow of sulfur foam at the top of the regeneration tower of the coke oven gas wet oxidation method adopts annular full flow. The diameter of the regeneration tower needs to be further expanded. With the continuous increase in the processing capacity of a single set of equipment, the diameter of the regeneration tower is getting larger and larger. The expansion of the top diameter forms an additional concentrated mass of the high tower. The equipment structure is complex, which is not conducive to structural safety. The sulfur foam at the center of the top of the large-diameter regeneration tower is also difficult to overflow and discharge smoothly; at the same time, the liquid level regulator of the desulfurization liquid is set outside the regeneration tower, or partially set inside the regeneration tower. The settings of these two positions will produce a certain eccentric load. The above-mentioned structural factors have an adverse effect on the safe and stable operation of the regeneration tower.

[0003] The existing patent CN107400540B discloses an electric liquid level regulating device for a desulfurization regeneration tower and a working method for a regeneration tower. The regeneration tower is provided with a desulfurization liquid tank and a foam tank, a desulfurization liquid storage tank is provided between the desulfurization liquid tank and the foam tank, and an electric liquid level regulating device is provided in the desulfurization liquid storage tank; the electric liquid level regulating device includes a desulfurization liquid overflow pipe, a liquid level regulating pipe and an electric actuator, the liquid level regulating pipe is driven by a lead screw to move up and down in the desulfurization liquid overflow pipe, and an electric actuator is provided at the top of the lead screw as a driving device; the desulfurization liquid overflow pipe serves as a guide rail when the liquid level regulating pipe moves, and a plurality of desulfurization liquid overflow ports are provided at the upper part of the desulfurization liquid overflow pipe along the circumferential direction, and a desulfurization liquid discharge port is provided at the corresponding part of the desulfurization liquid storage tank. The liquid level regulator of the device is provided on one side of the regeneration tower, which generates an eccentric load, which is not conducive to safe production. Summary of the invention

[0011] Compared with the existing technology, the beneficial effects of the utility model are:

[0012] 1. The desulfurization liquid overflow regulating pipe can be controlled by the hoist to move up and down in the desulfurization liquid discharge pipe, forming a built-in liquid level regulator to adjust the full flow height of the desulfurization liquid, and then adjust the liquid level of the desulfurization liquid in the regeneration tower, so that the interface between the desulfurization liquid and the sulfur foam is within a reasonable range, ensuring that the sulfur foam overflows into the annular foam full flow trough and multiple groups of radial full flow troughs. The liquid level adjustment is convenient, and the sulfur foam and desulfurization liquid are effectively diverted, reducing the construction and operation costs of the equipment.
