Description

Technical Field

[0001] The utility model relates to the technical field of formic acid product purification, in particular to a formic acid product purification device. Background Art

[0002] Formic acid product is a product that has been preliminarily purified and is often stored in a tank. As the formic acid solution is left standing at room temperature, flocs may also appear in the formic acid solution. Therefore, the flocs in the formic acid solution need to be filtered. The existing method for filtering flocs is often precipitation filtration. However, this filtration method requires a certain amount of time for precipitation and then filtration. This filtration time is relatively long and the efficiency is low.

[0003] The patent document of prior art announcement number CN219399029U provides a formic acid product purification device. When the formic acid product contains flocs, it enters the purifier through an auxiliary purification pipeline. The purifier is filled with a large number of spherical resin particles. The ion exchange performance of the resin is utilized. The resin material contains a large number of strongly acidic groups. After the solution is dissociated, the negatively charged groups contained in the body can adsorb and combine with other cations in the formic acid solution. Among them, the content of high-valent ions such as Ti4+ in the flocs is relatively high. The negatively charged groups generated by the resin material can adsorb and combine with high-valent ions such as Ti4+ in the flocs, thereby removing the attached flocs of the formic acid product.

[0004] Although the above-mentioned prior art purifies formic acid liquid by loading a large number of spherical resin particles in the purifier, the spherical resin particles in the purifier need to be replaced during long-term use. The removal and replacement of the spherical resin particles are relatively complicated and not convenient enough to meet people's needs. Therefore, we need a formic acid product purification device.
