Problems solved by technology

However, because the antiscalant has a certain impact on human health, even if it is placed before the reverse osmosis filter, it is difficult to completely filter it out through the reverse osmosis filter, especially when the function of the reverse osmosis filter fails, the pure water also contains scale inhibitors. agent, thereby causing harm to the user

Abstract

The invention discloses a reverse osmosis membrane water purifying device and a water purifier, wherein the reverse osmosis membrane water purifying device comprises a reverse osmosis filter element,a raw water pipeline, a purified water pipeline, a backflow pipeline, and a waste water pipeline, wherein the reverse osmosis filter element is provided with a water inlet, a purified water outlet anda waste water outlet; the raw water pipeline is connected with the water inlet, a booster pump is arranged on the raw water pipeline, and the purified water pipeline is connected with the purified water outlet; one end of the backflow pipeline is connected with the waste water outlet, the other end of the backflow pipe is connected to the raw water pipeline at a water inlet end of the booster pump, the waste water pipeline is connected with the waste water outlet, the waste water pipeline is internally provided with an antisludging agent module and a first waste water valve, and the antisludging agent module is located between the first waste water valve and the waste water outlet. The technical scheme avoids the phenomenon that the drinking water of a user contains an antisludging agent.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a reverse osmosis membrane water purification device and a water purifier. Background technique [0002] For the water system of the reverse osmosis water purifier, in order to ensure the front pressure of the reverse osmosis membrane and discharge the wastewater before the membrane, the wastewater valve at the wastewater discharge end is generally a small hole structure. However, due to the high ion concentration of the wastewater in front of the reverse osmosis membrane, it is very easy to form calcium and magnesium salt scales at the wastewater valve, thereby causing the wastewater valve to be blocked. In order to avoid clogging of the wastewater valve, scale inhibitors are usually added to the pre-filter elements of the entire water system. During the operation of the water system, the scale inhibitors in the pre-filter elements are released slowly, thereby preventing the fo...
