| titleOfInvention | Filter backwash using discontinuous air injection |
| abstract | The filter paper 100 of the water purification plant is a water treatment process that finally filters the fine suspended particles remaining without being removed from the sedimentation basin. The filter paper 100 is generally composed of a sand of about 0.5 ~ 1.0mm depth of about 60 ~ 100cm depth fine fine particles are detained in the space between the sand and the filter paper 100 is removed. If the pores between the filter paper 100 is kept detained like this, the filtration cannot be continued and the filter paper 100 should be washed. This process is referred to as backwashing (200). In general, when the filter paper 100 backwash 200 uses air and water. The reason for using air is to induce severe vibration of the filter paper 100, the filter medium 400 by using a rapid rising speed of air, and to use to desorb the detainment 300 attached to the filter medium 400 quickly, using water The water washing 202 serves to wash away the detainment 300 detached from the filter medium 400. In order to vibrate the filter medium 400 violently injecting air into the filter paper 100 is filled with water pushes out the water between the filter medium 400 and rises, the water in the filter layer as the volume of the injected air in the upper or horizontal The filter paper 100, the filter medium 400 is severely disturbed while moving. At this time, the detainees 300 attached to the filter medium 400 are efficiently detached from the filter medium 400 and then washed out of the detainer 300 detached from the filter medium 400 using water.n n n However, the vibration effect of the air washing 201 is filled with water in the filter bed so that the air is kept only for a few seconds passing by the water, and after that, even though the air continues to be injected, a path (airway) is formed so that the air Since only the air flows through the filter layer, there is no vibration at all, so the role of the air washing 201 can not be expected at all, resulting in only the waste of energy used in the air washing 201.n n n Therefore, if the reverse washing 200 proceeds while repeating the supply and interruption periodically without injecting air continuously during the back washing (200), the back washing (200) can fill the air around the air at the moment the air supply is stopped . When the merits are filled with water, the air is injected again to induce severe vibration of the filtrate, and thus the method is repeatedly carried out to effectively desorb the detainment 300 attached to the filtrate 400, thereby providing a quick backwashing effect. Can be represented,n n n Therefore, the present invention changes the vibration of the filter layer 100 to the discontinuous injection method of repeating the supply and interruption of the air through the opening and closing of the air pipe valve in the continuous air injection, which is the conventional method of backwashing the filter 100, and the filtrate vibration more. It is a method of increasing the efficiency of the filter paper 100 backwash 200 by causing the detaining material 300 attached to the filter medium 400 to be released faster.n n n Filter paper 100, backwash 200 air wash 201, water wash 202, detainment 300, filter media 400 |
