Description

Technical Field

[0001] This utility model relates to the field of anti-clogging materials for industrial pipelines, specifically an anti-clogging device for desulfurization slurry circulation pipelines. Background Technology

[0002] In existing wet desulfurization systems, the slurry circulation pipeline typically consists of multiple parallel pipelines, which are switched by valves to achieve operation under different loads. When the system load decreases or maintenance is required, some pipelines are shut down to save energy. However, the slurry (mainly composed of calcium sulfite, calcium carbonate, gypsum, etc.) in the shut-down pipelines is prone to forming a sediment layer due to factors such as settling, water evaporation, and crystallization reactions, eventually leading to pipeline blockage.

[0003] Traditional solutions have the following drawbacks: Manual dredging: This requires regular pipe disassembly and cleaning, is labor-intensive, and generates dust and corrosive slurry leaks, posing safety and environmental hazards. Continuous low-flow operation: This prevents slurry from clumping by maintaining a low flow rate within the pipe, but wastes energy and increases operating costs. Mechanical stirring: This involves adding a stirrer inside the pipe, but the equipment is complex, maintenance costs are high, and the stirring paddle is easily encapsulated by the slurry and becomes ineffective. Slurry buildup and clumping inside the pipe can easily cause blockages, affecting the normal spraying of slurry when the circulation pump restarts, impacting the normal operation of the desulfurization unit, and causing ash levels to exceed environmental standards.

[0027] Example

[0028] like Figure 1-6As shown, this utility model provides a technical solution: including a desulfurization tower 1, a conduit 2 with a sealed structure connected to the left end of the desulfurization tower 1, an installation shell 7 with a rotating structure installed at the left end of the conduit 2, the left end of the installation shell 7 being threadedly connected to a connector 13, the left end of the connector 13 being provided with an integrally structured connecting shell 6, located inside the connecting shell 6 and rotatably connected to a partition plate 14 via a rotating shaft 18, a threaded limiting bolt 15 being embedded at the top of the connecting shell 6, and the bottom end of the limiting bolt 15 penetrating through the upper end of the interior of the connecting shell 6;

[0029] A sealed transmission pipe 4 is installed at the left end of the connecting shell 6. The left end of the transmission pipe 4 is sealed to the slurry pipe 3 through a control valve 5. The top end of the transmission pipe 4 is sealed to the connecting pipe 8. The pressure regulating valve 10 installed on the connecting pipe 8 is located above the connecting pipe 8. The manual valve 9 installed on the connecting pipe 8 is located above the pressure regulating valve 10. The tail end of the connecting pipe 8 is connected to the air compressor 11. The bottom end of the connecting pipe 8 is equipped with a backflush pipe 12 located inside the transmission pipe 4.

[0030] A sealing gasket 16 is installed between the mounting housing 7 and the connector 13 to increase the sealing performance.

[0031] The left end of the conduit 2 is provided with an integrally structured barrier 17, and the inner diameter of the barrier 17 is the same as the inner diameter of the conduit 2, which facilitates the installation and disassembly of the connecting shell and the mounting shell.

[0032] The outer diameter of the mounting shell 7 is the same as the outer diameter of the connecting shell 6, and the inner diameter of the connecting shell 6 is the same as the inner diameter of the connector 13, which allows the slurry to flow smoothly.

[0033] The partition plate 14 and the connecting shell 6 are tangential, which facilitates the rotation of the partition plate when the slurry flows.

[0034] The limiting bolt 15 is located on the upper left side of the partition plate 14. The limiting bolt can block the partition plate and prevent the slurry from flowing back.

[0035] The backflush pipe 12 has an inclined structure, and there is a gap between the bottom end of the backflush pipe 12 and the bottom end of the inside of the transmission pipe 4. The backflush pipe can clear the slurry.

[0036] The inner diameter of the backflush pipe 12 is the same as that of the connecting pipe 8, which facilitates the transmission of compressed air to blow away the slurry.

[0037] In this embodiment, when the slurry pump stops, the control valve is opened, and compressed air enters the circulation pipeline through the backflush pipe. The airflow of compressed air keeps the slurry in the slurry pipeline in a flowing state, preventing it from accumulating and clumping. When the slurry circulation pump starts running, the manual air valve is closed to prevent slurry from flowing back into the compressed air pipeline and to avoid wasting compressed air.

[0038] Working principle:

[0039] I. Transmission Phase

[0040] During use, the desulfurization slurry is transported from the slurry pipeline 3 to the control valve 5. At this time, the control valve 5 is in the open state, and the slurry enters the transmission pipe 4 through the control valve 5.

[0041] The slurry flows into the connecting shell 6 in the transmission pipe 4. Since the baffle plate 14 is rotatably connected to the inside of the connecting shell 6 through the rotating shaft 18 and is tangential to the connecting shell 6, the impact force of the slurry pushes the baffle plate 14 to rotate around the rotating shaft 18, so that the internal channel of the connecting shell 6 is opened.

[0042] After the slurry is connected, it passes through the connector 13 and the mounting shell 7 in sequence. The sealing gasket 16 between the mounting shell 7 and the connector 13 ensures the sealing of the connection and prevents slurry leakage.

[0043] The slurry enters the conduit 2 through the mounting shell 7. The integrated baffle 17 at the left end of the conduit 2 has an inner diameter equal to that of the conduit 2 to ensure stable slurry delivery. Finally, the slurry enters the desulfurization tower 1 through the conduit 2 to complete a normal slurry cycle.

[0044] II. Anti-backflush stage

[0045] When the slurry pump stops working, start the air compressor 11 and open the manual valve 9 on the connecting pipe 8 at the same time;

[0046] Compressed air is delivered through connecting pipe 8, and the pressure of the compressed air is adjusted by pressure regulating valve 10 to achieve a suitable backflush intensity.

[0047] Compressed air enters the transmission pipe 4 through the backflush pipe 12 installed at the bottom of the connecting pipe 8. The backflush pipe 12 has an inclined structure and its bottom end is separated from the bottom end of the transmission pipe 4. It can blow the slurry that has stopped transmitting toward the desulfurization tower 1 to achieve the function of unblocking and prevent the slurry from condensing into lumps in the transmission pipe.

[0048] Compressed air forms a backflow in the transmission pipe 4, which impacts and removes blockages in the pipe. The blockages are pushed or broken up by the backflow and discharged with the subsequent slurry flow.

[0049] During the backflushing process, the rotation of the partition plate 14 can be restricted by rotating the limit bolt 15 to prevent the slurry from flowing back.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
