Full-automatic cleaning and filtering system

Abstract

The invention provides a full-automatic cleaning and filtering system. The full-automatic cleaning and filtering system comprises a plurality of filters connected in parallel, an inlet pipeline, an outlet pipeline and a back flushing pipeline, a deslagging pipeline, wherein the inlet pipeline, the outlet pipeline and the back flushing pipelineare connected with the filters, and the deslagging pipeline is arranged below the filters; the filters are communicated with the deslagging pipeline through deslagging valves at the bottoms of the filters; a flushing valve is arranged at one end of the deslagging pipeline; an inlet valve is arranged on the inlet pipeline; an outlet valve is arranged on the outlet pipeline; and a back flushing valve is arranged on the back flushing pipeline. The filtering system is provided with a unique quick uncovering structure, so that filtering elements are convenient to replace; the filtering system integrates the valves, instruments and electric control units, is compact in overall structure, small in occupied area and suitable for being used on a ship; the filtering system can realize full-automatic operation and continuous operation without manual operation and maintenance; and stable work of the system can be ensured just with the filtering elements regularly replaced, so that the maintenance cost of the system is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of water treatment filters, in particular to a fully automatic cleaning and filtering system. Background technique [0002] The purpose of the International Maritime Organization IMO "Sulfur Limit Order" is to reduce the sulfur content of ship fuel from 3.5% in most parts of the world to 0.5%, or to install desulfurization towers on ships to prevent sulfur oxides from being released into the atmosphere . [0003] In order to cope with the IMO sulfur limit order, considering the cost of rectification and later operation costs, equipping ships with scrubbers is one of the most effective means in the industry at present. However, the washing water has adverse effects on the marine environment, and how to deal with the desulfurization wastewater in the closed system has become a topic of concern. [0004] Removal of ash powder, heavy metals, and PAH (polycyclic aromatic hydrocarbons) in wash water is the key t...

Problems solved by technology

[0006] The purpose of the present invention is to disclose a fully automatic cleaning and filtering system designed for desulfurization wastewater from ships. The system adopts the structural design of backwashing / backflushing, automatic purification and slag discharge, and the effluent meets the discharge standards of the classification society for washing water, effectively It solves the problem of unstable filtration efficiency and substandard filtration precision, and realizes the goal of "zero emission"
