Description

Reclaimed water reverse osmosis online diagnosis type automatic cleaning device and application thereof

Technical Field

The invention relates to a reclaimed water reverse osmosis online diagnosis type automatic cleaning device and application thereof, belonging to the technical field of water treatment equipment.

Background

Aiming at the current trend of improving the utilization rate of water resources and increasing the complexity of water quality components in large environment, the requirement of the water treatment industry on reverse osmosis equipment taking complex water quality such as reclaimed water, high-concentration drained water and the like as inlet water is promoted, and the inherent percentage of the market is continuously increased. And the cleaning of the conventional equipment has no pertinence, the requirements of the equipment cannot be met, and then new standards for reverse osmosis online cleaning, maintenance and repair are derived. In order to solve the defects of fast pollution speed, various types, microorganism breeding, high cleaning frequency, high maintenance agent consumption and large manual occupation of the equipment, the invention discloses an on-line diagnosis automatic cleaning device to solve the problems.

The conventional reverse osmosis equipment is cleaned on line once in 6-12 months, but the reverse osmosis with special water such as reclaimed water as inlet water needs to be cleaned once in 7-30 days (the cleaning frequency depends on the equipment data change and the water quality condition), and the cleaning frequency is higher than that of the conventional equipment. And a minimum of 2 workers are needed in each online cleaning, and 8 hours of cleaning time is needed for a single device. The device can greatly save labor consumption.

Both conventional cleaning and conventional automatic cleaning systems have the characteristics of single flow and lack of pertinence in cleaning. The complex water quality and the complex water source of the reclaimed water equipment promote the difficult cleaning of the dirt blockage generated by the reclaimed water reverse osmosis and the diversity of the water quality and the water source. The conventional single cleaning process cannot be completely and effectively solved, and pollutants which are not cleaned completely enter the rear section along with the pressure along with the time, so that various indexes of the equipment cannot be recovered due to accumulation. Different cleaning is carried out to equipment through data presetting to this device, has improved the cleaning efficiency of equipment greatly, has also played the maintenance equipment simultaneously and then prolonged equipment life's characteristics.

The water inlet source of the reclaimed water equipment has complex and various water quality. The device has the characteristics of partial water quality, is very suitable for the growth of microorganisms, has very quick growth speed, has no discrimination capability in the conventional cleaned sterilization device and the conventional automatic sterilization device, and only performs sterilization according to a certain period, but once the device has the generation of microbial pollution and the system does not perform sterilization in time, the result inevitably has certain influence on the device. The device can increase or reduce the sterilization dosage of the system in due time through the data representation of reverse osmosis fouling and microorganism fouling. The purposes of protecting equipment, saving medicine and saving labor are achieved.
