Description

TECHNICAL FIELD

[0002] Active carbon is widely used in the purification of domestic water and industrial water such as food industry, chemical industry, electric power, dechlorination, oil removal and deodorization etc. In the process of desalted water treatment, active carbon filter is set in front of cation exchanger. Its surface is full of micropore with average diameter of 2-3nm, which can adsorb organic matter and heavy metal ions in water, remove peculiar smell and residual chlorine in water, so as to protect subsequent ion exchanger, reverse osmosis membrane or other sensitive equipment, prevent them from being polluted by organic matter and oxidized by residual chlorine, and prolong the service life of equipment.

[0003] With the gradual increase of dirt intercepted by active carbon filter, it needs to be backwashed in time. Backwashing is very important for the normal operation of filter, if not effectively backwashed, the dirt in filter layer cannot be effectively removed. When the dirt accumulates more, it may be bonded with active carbon particles into carpet or mud ball, which seriously affects the operation of filter. Active carbon filter adopts water flushing and air assisted scrubbing mode for backwashing, and its backwashing system is composed of backwashing water inlet system and backwashing air inlet system. During long-term operation, active carbon filter will be gradually broken into small particles due to mechanical friction and oxidation of residual chlorine. Part of small particles enter the small hole of backwashing air nozzle, causing the blockage of air nozzle, affecting the backwashing effect of filter, leading to the decrease of filter flux, and even causing the damage of auxiliary equipment roots blower due to excessive current. Since backwashing air nozzle is located at the lower part of active carbon bed layer, the active carbon bed layer must be completely cleaned out during each maintenance, which greatly prolongs the downtime of filter.

[0004] As shown in Figure 3 Fig. 1 is a structural schematic diagram of existing active carbon filter 100. It contains backwashing air inlet pipeline 101, manhole and filler loading port 102, exhaust pipe 103, water distributor 104, water inlet pipe 105, active carbon loading area 106, manhole door 107, backwashing air nozzle 108 and blowdown valve 109.
