The bell shape of stifled or blind plate closure, the periphery of the opening are evenly arranged with multiple holes as gas channel, facilitate gas
Into airflow pipeline, the aperture in the hole is preferably 3mm~8mm.According to both the above structure, more preferably energy dissipating can be obtained
Voltage regulation result.
It is also preferred that for the ease of being replaced to the energy dissipating inlet part 73, the energy dissipating pipe 72 disappears with described
Energy inlet part 73 is using threaded connection.Certainly, however it is not limited to this, the energy dissipating pipe 72 and 73 one of energy dissipating inlet part
The present invention can also be realized by setting or being fixed together by loose joint etc..
In addition, the length that the lower end of the energy dissipating pipe 72 is stretched out from 50 downside of filter plate is preferably 5cm~15cm.By
This, is conducive to discharge the excessive air pressure of 50 downside of filter plate, can obtain more preferably energy dissipating voltage regulation result.In addition, such as preceding institute
It states, 72 outside of energy dissipating pipe and 50 seamless combination of filter plate.Preferably, the energy dissipating pipe 72 and the filter
It firmly inserts and stands in the filter plate 50 using sand material and joint filling sealing material, the energy dissipating pipe 72 between plate 50.Have as a result,
Preferably fastening, sealing effect.
In the present invention, the voltage stabilizing energy dissipator 70 the filter beam 30 and the filter tank 10 of both sides pool wall 10c,
There is laying between 10d and between the intermediate adjacent filter beam 30, and have arrangement in the front and rear sides in the filter tank 10.Into
One step, the voltage stabilizing energy dissipator 70 is mounted near described pool wall 10a, 10b, and is passed through stent and consolidated the energy dissipating pipe 72
It is fixed.Concrete structure is as described below.
As shown in Fig. 2, filter beam 30 in both sides with the both sides the pool wall 10c for filtering the opposite filter tank 10 of beam 30,
Between 10d and between the adjacent filter beam 30, the voltage stabilizing energy dissipator 70 is both provided with.In addition, in the filter
Near the both sides pool wall 10a, the 10b that are connected with the filter beam 30 in pond 10, the voltage stabilizing energy dissipator 70 is both provided with.By setting
Multiple voltage stabilizing energy dissipators 70 are put, it can be more effectively by the extra gas in entire 50 downside of filter plate in the filter tank 10
(water) is balancedly discharged, gas (water) layer energy dissipating voltage stabilizing to 50 downside of filter plate.
In the present invention, the energy dissipating pipe 72 of the voltage stabilizing energy dissipator 70 is preferably separately fixed at the filter by stent
On pond 10, described pool wall 10a, 10b of both sides for being connected with the filter beam 30.Further each voltage stabilizing is disappeared as a result,
Energy device 70 is fastened in the filter tank 10.
In addition, the above-mentioned voltage stabilizing energy dissipator based on the present invention, the present invention also provides a kind of voltage stabilizings for the device to disappear
It can method.In the following, the method is described in detail with reference to Fig. 3.The voltage stabilizing energy dissipating method of the present invention includes following three and walks successively
Rapid S100, S110, S120.
In the step s 100, the air purge valve 21 to the filter tank 10 and the energy dissipating valve 71 carry out automatic interlock setting, make
It can be opened and simultaneously close off simultaneously with the energy dissipating valve 71 with opening with closing when the air purge valve 21 is under auto state.
In step s 110, open the air purge valve 21 and carry out air water backwash, meanwhile, the voltage stabilizing energy dissipator 70 starts
Work, gas-bearing formation, water layer (mainly gas-bearing formation, also including water layer) energy dissipating voltage stabilizing to 50 downside of filter plate, i.e. by the air purge
Valve 21 is opened, and is started air water backwash operation to the filter tank 10, correspondingly, is set by the automatic interlock, the energy dissipating valve
71 open with the air purge valve 21 and are opened, under pressure differential effect, gas, water on the downside of the filter plate (mainly gas,
Including little water) it is discharged and straight-through air from the energy dissipating inlet part 73 via the energy dissipating pipe 72 and the energy dissipating valve 71,
Thus gas-bearing formation, water layer energy dissipating voltage stabilizing to 50 downside of filter plate.
In the step s 120, when air water backwash is not required, air water backwash operation is terminated, meanwhile, the voltage stabilizing energy dissipating dress
Put 70 power cut-offs, i.e. air purge valve 21 is closed, terminates air water backwash operation, at the same time, is set by the automatic interlock,
The energy dissipating valve 71 is closed with the air purge valve 21 and closed.
The method according to the invention, by step S110, gas-bearing formation (water layer) energy dissipating voltage stabilizing to 50 downside of filter plate, energy
When preventing from carrying out air water backwash operation due to the dirty stifled or algal suspension of the filter 40 grows pollution, backwash gas (water) can not pass through institute
It states filter 40 to discharge in time, forms high pressure gas (water) layer in 50 downside of filter plate, the briquetting of the filter plate 50 is caused to come off, institute
State 50 top plate of filter plate collapse material the problems such as.
In conclusion the present invention by setting voltage stabilizing energy dissipator, can be solved preferably because of the blocking of filter air-flow slit, algae
Class growth etc., when carrying out air water backwash operation, filter plate lower floor gas (water) pressure can not discharge, and filter plate lower part pressure is caused to increase suddenly,
Filter plate briquetting is triggered to come off, the problems such as filter plate top plate and filtrate collapse.
The voltage stabilizing energy dissipator and its method in the filter tank of the present invention are mainly used for sewage treatment field, but to this field skill
For art personnel, it is contemplated that it is contemplated that the present invention may be use with other association areas.
Explanation and practice with reference to the present invention disclosed here, the other embodiment of the present invention is for those skilled in the art
