Abstract
The utility model discloses a novel comet type fiber filter tank which comprises a gas-water distributing channel. The gas-water distributing channel is divided into two independent layers. The bottom layer is a water distributing channel. The top layer is a gas distributing channel. Water distributing holes which are communicated with the bottom space of the filter tank is reserved on the side wall of the water distributing channel. Round gas distributing holes which are communicated with the bottom space of the filter tank are reserved on the side wall of the gas distributing channel. By the novel comet type fiber filter tank, even gas distribution during back washing is achieved, back washing effect is fine, and cost is lowered.
Description
Technical field
The utility model relates to a kind of filter tank, especially a kind of novel comet type fibre filter.
Background technology
According to comet type fibre filter engineering rules (CECS 276:2010) requirement, single pond filter plate is installed horizontal error must not be greater than 5mm, and corresponding backwash gas distribution circular hole (ф 50 embedded steel tubes) horizontal error also must not be greater than 5mm.Because in the civil engineering process during pre-buried ф 50 steel pipes;, cement makes pre-buried ф 50 steel pipes height off normal when vibrating easily; Be difficult to satisfy above-mentioned requirements; Thereby monolithic filter plate (4 ф 50 steel pipes), filter tank monolateral (a row ф 50 steel pipes) occur, filter tank bilateral (relative two row ф, 50 steel pipes) horizontal error is very big, horizontal error can reach 40mm in part comet type fibre filter engineering.
Because above-mentioned backwash gas distribution circular hole horizontal error is too big; The time gas distribution non-uniform phenomenon (inorganization gas distribution) that filter back washing can occur; The high position gas output in the pre-buried position of gas distribution circular hole is big; The low position gas output in the pre-buried position of gas distribution circular hole is little, even does not have gas, is difficult to reach the effect of backwash.The part engineering for reaching the effect of backwash, must increase the time of backwash sometimes, thereby increases the water consumption of backwashing water, increases the power consumption of backwash equipment, increases cost.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, a kind of novel comet type fibre filter is provided, and it is even that this filter tank can reach when backwash gas distribution, and backwash effect is good, reduces cost.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of novel comet type fibre filter; Comprise that air water distributes canal; Said air water distributes canal to be divided into two-layer structure independent of each other up and down, and bottom is a distributing channel, and the upper strata is the distribution corridor; Said distributing channel sidewall is provided with the distributing hole that is connected with the filter tank bottom space, and said distribution corridor sidewall is provided with the gas distribution circular hole that is connected with the filter tank bottom space.
Said gas distribution circular hole links to each other with the backwash gas distribution system through the pipeline in the distribution corridor.
Said pipeline is provided with control valve.
Said distributing channel links to each other with the backwash water source.
Backwash gas distribution system in the utility model, and other structures in the filter tank are identical with existing comet type fibre filter, repeat no more at this.
The utility model adopts and distributes canal (lattice) to be divided into two lattice up and down existing air water, and bottom sieve frame is a distributing channel, and last lattice are the distribution corridor, and aqueous vapor is not separately disturbed mutually.Gas distribution system adopts the high strength cement cast-in-site, and backwashing water carries out backwash through distributing hole to the filter tank by distributing channel; The backwash gas distribution system is connected to the gas distribution circular hole by the distribution corridor through pipeline, and valve regulated is set on pipeline.Because gas distribution system all is to connect through pipeline from blower fan to the gas distribution circular hole, the phenomenon that becomes flat can not occur, and can control the gas output of every monolithic filter plate through the valve regulated that is provided with on the pipeline, and is even to reach gas distribution.It is even that this filter tank can reach when backwash gas distribution, and backwash effect is good, reduces cost.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Shown in Fig. 1-3; The novel comet type fibre filter comprises that air water distributes canal 17, and said air water distributes canal 17 to be divided into two-layer structure independent of each other up and down; Bottom is a distributing channel; The upper strata is the distribution corridor, and said distributing channel sidewall is provided with the distributing hole 15 that is connected with filter tank bottom space 13, and said distribution corridor sidewall is provided with the gas distribution circular hole 14 that is connected with filter tank bottom space 13.Gas distribution circular hole 14 links to each other with the backwash gas distribution system through the pipeline in the distribution corridor.Said pipeline is provided with control valve.Said distributing channel links to each other with the backwash water source.
Backwash gas distribution system in the utility model, and other structures in the filter tank (as: total inlet channel 1, the side's of water inlet gate 2, water inlet square hole 3, influent weir 4; V-type groove water inlet side opening 5, V-type groove 6, surface sweep washing hole 7, filtrate catching sheet 8, filtrate 9; Filter plate 11, strainer head 12, dirt discharge groove 16, water seal tank 18, effluent weir 19; Clear water canal 20, purge valve 21, outlet valve 22, initial filter water canal 23; Rinse water valve 24, flushing air valve 25, exhaust gas valve 26) identical with existing comet type fibre filter, repeat no more at this.
The utility model adopts and distributes canal 17 (lattice) to be divided into two lattice up and down existing air water, and bottom sieve frame is a distributing channel, and last lattice are the distribution corridor, and aqueous vapor is not separately disturbed mutually.Gas distribution system adopts the high strength cement cast-in-site, and backwashing water carries out backwash by distributing channel through 15 pairs of filter tanks of distributing hole; The backwash gas distribution system is connected to gas distribution circular hole 14 by the distribution corridor through pipeline, and valve regulated is set on pipeline.Because gas distribution system circle 14 holes from the blower fan to the gas distribution all are to connect through pipeline, the phenomenon that becomes flat can not occur, and can control the gas output of every monolithic filter plate through the valve regulated that is provided with on the pipeline, and are even to reach gas distribution.
Though the above-mentioned accompanying drawing that combines is described the specific embodiment of the utility model; But be not restriction to the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technical scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.
