Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, specifically to a filtration system that integrates regeneration and slag discharge metering. Background Technology

[0002] The filtration systems widely used in current industrial production (such as plate and frame filters, bag filters, centrifugal filtration equipment, etc.) generally suffer from the following technical bottlenecks:

[0003] (1) Low efficiency in cleaning filter residue affects continuous production.

[0004] Manual cleaning mode: Most traditional filtration equipment requires manual disassembly of filter elements or filter plates after shutdown to remove slag. Each cleaning takes 30 to 120 minutes, resulting in a reduction of equipment utilization rate by more than 30%.

[0005] Incomplete mechanical slag removal: Some automated equipment uses scrapers or vibration to remove slag, but 5% to 15% of sticky slag will still remain in the filter screen pores, which will lead to a decrease in filtration efficiency over a long period of time.

[0006] (2) The backwashing process is crude and wastes resources seriously.

[0007] Fixed-cycle flushing: Most systems use a time-controlled mode (e.g., flushing every 8 hours), which cannot be adjusted according to the actual degree of blockage, causing the following problems:

[0008] Flushing when there is no blockage: wastes 20% to 40% of the cleaning medium (water / gas).

[0009] Severe blockage followed by flushing: requires extended flushing time, increasing energy consumption by more than 50%.

[0010] Poor rinsing uniformity: Traditional single-point backwashing causes local over-rinsing of the filter element while other areas are not cleaned enough, shortening the filter element's lifespan.

[0011] (3) The amount of slag discharge cannot be accurately measured, and the process control is lagging.

[0012] The drawback of the gravimetric method: Some companies use offline weighing (such as collecting slag and measuring it with a weighbridge), but there is a time delay (2-4 hours), and it cannot be fed back to the DCS system in real time.

[0013] The volumetric method has large errors: estimating the slag discharge volume using the slag hopper level is affected by changes in material density, resulting in an error as high as ±15%. Utility Model Content

[0014] This invention provides a filtration system that integrates regeneration and slag discharge metering, solving the problems of low slag cleaning efficiency, crude backwashing process, and inaccurate slag discharge measurement in current industrial filtration systems.

[0019] The backwashing assembly includes a main flushing pipe, a first flushing pipe, and a second flushing pipe. The first flushing pipe and the second flushing pipe are arranged in parallel and are both connected to the main flushing pipe. The output end of the first flushing pipe is connected to the effluent pipe, and the output end of the second flushing pipe is connected to the filter cake metering and settling tank.

[0020] The metering tank flushing pipe has one end connected to the feed pipe and the other end connected to the sediment metering settling tank. The metering tank flushing pipe is equipped with a regeneration pipe and a metering tank exhaust balance pipe.

[0021] Furthermore, solenoid valve switches are installed on the first air blowing pipe, the second air blowing pipe, the third air blowing pipe, the first flushing pipe, the second flushing pipe, the feed pipe, the discharge pipe, the reagent pipe, the metering tank flushing pipe, the regeneration pipe, and the metering tank exhaust balance pipe.
