Description

Technical Field

[0001] This utility model relates to the field of material collection technology, and in particular to an optimized desulfurization pulping system. Background Technology

[0002] The existing desulfurization slurry preparation system operates as follows: A limestone slurry tank in a power plant supplies slurry to the primary and secondary absorption towers of the unit. The limestone slurry tank is replenished with water via desulfurization process water pumps. These pumps are used by numerous users, primarily for replenishing the slurry tank, cooling the oxidation air, cooling the mechanical seals of the 380V desulfurization equipment, and flushing pipelines. When both units are operating at high load, the slurry supply surges. Even with the slurry tank's pneumatic valve constantly open, it is difficult to meet the slurry preparation demand. Furthermore, under these conditions, the pressure in the process water header is low, posing a potential safety hazard of increased oxidation air temperature in the absorption towers and increased bearing temperature in the desulfurization equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an optimized desulfurization pulping system. To achieve the above objectives, this utility model adopts the following technical solution:

[0004] An optimized desulfurization slurry preparation system includes a powder silo, a slurry tank, and a plant-use recovery water pool. The bottom of the powder silo has two funnel hoppers arranged side by side. The funnel hoppers are connected to a discharge pipe and feed material into the slurry tank through the discharge pipe. The discharge pipe is equipped with a feed valve and two isolation valves. The feed valve is located between the two isolation valves. The top of the slurry tank is equipped with a paddle agitator. The slurry tank is connected to a process pipe for water supply. The plant-use recovery water pool replenishes water to the slurry tank through a water pump.

[0005] Furthermore, the funnel chamber is connected to an air blowing pipe, and a heater is installed on the air blowing pipe.

[0006] Furthermore, the heater is an electric heater.

[0007] Furthermore, a bag filter is installed at the top of the powder hopper.

[0008] Furthermore, an overflow pipe is provided at the top of the slurry tank.

[0009] Furthermore, the top of the slurry tank is equipped with a plant-use recycled water replenishment pipe.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By installing two parallel funnel hoppers at the bottom of the powder silo, along with corresponding discharge pipes, feed valves, and shut-off valves, the material inflow rate can be effectively controlled, avoiding problems such as blockage or uneven feeding that might occur with a single funnel hopper. Simultaneously, installing a paddle agitator in the slurry tank ensures uniform slurry mixing and improves slurry quality. Furthermore, replenishing the slurry tank with water from the plant's recycled water pool reduces the need for fresh water resources, addressing situations of sudden demand surges, lowering production costs, and being more environmentally friendly.
