Technical Field

[0001] The utility model relates to a sulfur foam treatment device for chemical desulfurization, belonging to the technical field of sulfur foam treatment for chemical desulfurization. Background Art

[0002] In the chemical product desulfurization process, the sulfur foam floating on the top of the regeneration tower will flow into the foam tank by gravity using the potential difference. In the prior art, after the sulfur foam is stirred by the agitator in the foam tank, it will be pumped into the molten sulfur kettle by the foam pump to heat up the sulfur and melt the sulfur. The molten sulfur liquid is cooled and flaked by a slicer and then packaged for storage. This method will cause the molten sulfur kettle to consume a large amount of desulfurization liquid when the foam pump is pumped into the sulfur foam. At the same time, a large amount of desulfurization liquid is heated by the molten sulfur kettle and then returned to the system. A corresponding cooling system needs to be set up, which further increases energy consumption. Utility Model Content

[0004] The chemical product desulfurization sulfur foam treatment device described in the utility model comprises a plate and frame filter press, a guide hopper and an open sulfur melting kettle. A sulfur mud filter cake collecting hopper is provided at the bottom of the plate and frame filter press, and a crushing box is provided at the bottom of the sulfur mud filter cake collecting hopper. A crushing shaft is rotatably connected in the crushing box, and a plurality of crushing teeth are fixedly connected to the crushing shaft. One end of the crushing shaft extends out of the crushing box and is connected to a crushing motor. A sulfur mud crushing outlet is provided at the bottom of the crushing box, and the sulfur mud crushing outlet is connected to the top of the guide hopper. The bottom of the guide hopper corresponds to the feeding port of the open sulfur melting kettle up and down.

[0005] Furthermore, the crushing motor is installed outside the side wall of the crushing box.

[0006] Furthermore, a liquid adding port is correspondingly installed above the guide hopper, a liquid adding solenoid valve is provided on the liquid adding port, and the liquid adding port is connected to the mother liquid supply pipeline.

[0007] Furthermore, it also includes a material elevator, which is provided with a feed hopper and a discharge port, the feed hopper corresponds to the sulfur mud crushing outlet, and the discharge port corresponds to the guide hopper.

[0008] Furthermore, a first flange is provided at the bottom of the sulfur sludge crushing outlet, and a second flange is provided at the top of the feed hopper, and the first flange and the second flange are fixedly connected by bolts.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The chemical product desulfurization sulfur foam processing device described in the utility model can pre-filter the sulfur foam into a filter cake through a plate and frame filter press, and then crush the filter cake and add it into an open sulfur melting kettle. A large amount of desulfurization liquid will not enter the open sulfur melting kettle, and only a proper amount of mother liquor needs to be added, thereby effectively reducing the energy consumption of the open sulfur melting kettle. At the same time, since the desulfurization liquid is returned to the system from the plate and frame filter press and is not heated by the open sulfur melting kettle, there is no need to set up an additional cooling system, which further reduces the energy consumption.

The bottom of the guide hopper 8 corresponds to the feeding port of the open sulfur melting kettle 9 up and down.

[0017] When in use, the sulfur foam stirred by the stirrer in the foam tank is pumped to the plate and frame filter press 1 by the foam pump, and the plate and frame filter press 1 filters the sulfur foam into a sulfur mud filter cake, and the desulfurization liquid returns to the system through the desulfurization liquid outlet of the plate and frame filter press 1, and then the sulfur mud filter cakes fall off one by one, and fall into the crushing box 3 under the action of the sulfur mud filter cake collecting bucket 2, and the crushing motor 6 is activated, which will drive the crushing shaft 4 to rotate, thereby driving the crushing teeth 5 to rotate, and hitting the falling sulfur mud filter cake to break the sulfur mud filter cake, and then, the crushed sulfur mud enters the guide hopper 8 through the sulfur mud crushing outlet 7, and enters the open sulfur melting kettle 9 under the guidance of the guide hopper 8, and then adds an appropriate amount of mother liquor into the open sulfur melting kettle 9 and closes the feed valve of the open sulfur melting kettle 9, and then the open sulfur melting kettle 9 can carry out the temperature-raising sulfur melting operation, and the sulfur liquid after sulfur melting is cooled and flaked by the slicer, and then packaged and stored.

[0018] The chemical product desulfurization sulfur foam processing device described in the utility model can pre-filter the sulfur foam into a filter cake through a plate and frame filter press 1, and then crush the filter cake and add it to an open sulfur melting kettle 9. A large amount of desulfurization liquid will not enter the open sulfur melting kettle 9, and only an appropriate amount of mother liquor needs to be added, thereby effectively reducing the energy consumption of the open sulfur melting kettle 9. At the same time, since the desulfurization liquid is returned to the system from the plate and frame filter press 1 and is not heated by the open sulfur melting kettle 9, there is no need to set up an additional cooling system, which further reduces energy consumption.
