A multi-stage filter tubular acid separator with constant flow

Abstract

This invention provides a multi-stage filter tube acid separator with stable flow. The separator includes an outer frame, an inlet pipe fixedly connected to the outer surface of the frame, a main flow pipe fixedly connected to the outer surface of the inlet pipe, a branch pipe fixedly connected to the outer surface of the main flow pipe, a first filter screen fixedly connected to the inner surface of the main flow pipe, a fixed frame fixedly connected to the upper surface of the first filter screen, and a first motor fixedly connected to the upper surface of the fixed frame. Through the use of a cleaning mechanism and a conveying mechanism, the cleaning mechanism scrapes and removes solid impurities from the surface of the first filter screen, preventing clogging and ensuring efficient flow separation.

The cleaning and conveying mechanisms enable continuous acid flow separation during the cleaning process, eliminating the need to stop the flow separation for cleaning to maintain the cleanliness of the filter screen, thus improving work efficiency.

Description

Technical Field

[0001] This invention relates to the field of tubular acid separator technology, specifically a tubular acid separator with a constant flow multi-stage filter. Background Technology

[0002] As is well known, the function of an acid distributor is to ensure uniform acid distribution on the packing material. When flue gas enters via acid convection, sulfur trioxide is absorbed upon contact with the acid. Sufficient sulfur trioxide absorption is crucial for the tower's performance and is also an important function of uniform acid distribution. Uneven acid distribution can cause problems such as excessive acid mist entrainment and short-circuiting of sulfur trioxide within the tower, leading to exceeding emission standards and causing excessive corrosion of downstream equipment. Currently, both domestically and internationally, tubular acid distributors and cast iron trough-type acid distributors are commonly used on the packing material in packed absorption and drying towers.

[0003] When applying for this invention, the applicant, after searching, discovered a Chinese patent that discloses a "multi-stage filter tubular acid separator with flow stabilization," application number "201810197060.5." This patent mainly uses multi-stage filtration and a flow stabilizing tank. After the overflow is buffered by the multi-stage filtration and the flow stabilizing tank, the liquid level in the main acid pipe and the branch acid pipe tends to be stable. The flow stabilizing tank adopts a bottom-in, top-out overflow structure to achieve buffering, flow stabilization, and overflow effects, and can filter impurities in the sulfuric acid medium. Although the patent guarantees a uniform acid output in the specification, solid impurities in the acid accumulate before the filter screen and are difficult to clean due to the corrosiveness of the acid. With prolonged use, the filter screen becomes clogged, and the fastest flow rate decreases or becomes difficult to flow. Therefore, based on the applicant's invention, a device that can clean and divert solid impurities in the acid solution solves the problem of reduced work efficiency caused by the need to stop diversion for cleaning when the filter screen is clogged. Summary of the Invention

[0024] Working principle: Acid flows into main pipe 3 through inlet pipe 2.

The slider 9 drives the wedge 17 to scrape the first filter screen 5. Solids on the surface of filter screen 5 are scraped between the second filter screen 16 and the first filter screen 5 and carried out. The slider 9 drives the connecting plate 13 to move upward at the same time, so that the second filter screen 16 and the wedge 17 move at the same frequency. After the solid impurities are carried out, they slide from the inclined surface of the wedge 17 to between the scrapers 23. The second motor 20 drives the drive roller 21 to rotate.
