Abstract
Description
본 발명은 다공질 여과체와 초음파를 이용하여 오수와 폐수를 여과, 정화하는 오,폐수 처리장치에 관한 것이다.The present invention relates to a wastewater treatment apparatus for filtering and purifying sewage and wastewater using a porous filter medium and ultrasonic waves.
지금까지의 오,폐수 처리장치는 여과체만을 이용한 여과방법과 원심력과 화공약품 등을 이용한 정화 처리방법 등 여러가지 방법이 있었으나 여과체를 이용한 경우 여러차례 여과로 인한 장시간 소요와 여과체를 자주 교체시켜야 하고 원심력을 이용한 경우 설치 및 처리비용이 많이 들고 화공약품을 사용하는 경우 처리비용증가와 함께 또 다른 환경오염의 원인이 되었다.Until now, there have been various methods of wastewater treatment equipment such as filtration method using only filter medium and purification method using centrifugal force and chemicals.However, when using filter medium, it takes long time due to filtration several times and frequent replacement of filter medium. The use of centrifugal force is expensive to install and treat, and the use of chemicals increases the cost of treatment and is another source of environmental pollution.
본래 산업적으로 이용하는 초음파는 10㎑ 이상의 진동수를 가진 음파로서 진동으로 액체입자를 분산시켜 미세화시키고 공동현상을 이르켜 공동의 표면에 입자들이 붙어서 팽창하여 공동이 폭발할 때 발생하는 폭발에너지로 수중의 입자들을 분쇄시키고 세균의 세포막도 파괴시키는 것으로 본 발명에서는 이러한 초음파를 이용하여 오,폐수를 원통형 다공질 여과체로 고형물질을 걸러낸후 초음파로서 물분자를 미세화 시키므로서 물의 응집력 및 표면장력을 약화시키고 오염물의 결정구조 파괴와 박테리아 등의 세균 세포막을 파괴시켜 여과된 물을 정화시키고 특히 오,폐수를 여과시켜주는 다공질 여과체 내주연에 여과시마다 쌓이는 고형물질을 벤츄리식 역세척수 흡입노즐로 흡입하여 외부로 배출시켜 다공질 여과체를 교환하지 않고 반영구적으로 사용할 수가 있는 것으로 도면에 의거 상세히 설명하면 다음과 같다.Originally, industrial ultrasonic waves are sound waves with a frequency of 10 Hz or more, which disperse liquid particles by vibration and make them finer, and reach the cavitation phenomenon. In the present invention, the wastewater is filtered through a cylindrical porous filter using ultrasonic waves, and then the water molecules are refined by ultrasonic waves to reduce water cohesion and surface tension and to determine contaminants. Purify the filtered water by destroying the structure and destroying bacterial cell membranes such as bacteria.In particular, the solid material accumulated every time in the inner circumference of the porous filter medium that filters the wastewater and the wastewater is sucked with a venturi backwash water suction nozzle and discharged to the outside. Semi-permanently without replacing the porous filter medium If it described in detail based on the drawings that can be used as follows.

The cylindrical porous filter body 12 is sandwiched between the two disks, and the outer part is fastened with both disks and nuts with a plurality of connecting rods 13 to form an outer frame, and on both sides of the center of the cylindrical body 1, It is circulated with the inside of the distribution pipe in the middle lower portion of the distribution pipe 20 penetrating the inside of the cylindrical shafts 11 and 11a, and becomes the upper and lower light type so that the lower portion thereof is enlarged to the front and rear sides, and to both side stone bands 24a at the lower inner end. The venturi backwash water suction nozzle 24 having a narrow interval is attached so as to be close to the inner circumference of the cylindrical porous filter body 12, and the inside of the middle left side of the distribution pipe having the solenoid control valve 23 attached to the right exposure tube is plated. To 21 and drill the outflow hole 22 in the left tube Ultrasonic vibrator 32 of the ultrasonic oscillator 31 so as to cut the middle circumferential wall of the front side and attach the purification vessel 30 having the discharge pipe 33 and the differential pressure switch 34 installed thereon, and the ultrasonic waves are radiated toward the cylindrical body. Reference numeral 4 denotes a drain valve.
그리고 원통체(1) 내부의 한쪽 원판(10)의 외부쪽 원통축(11)에 임펠러(15)를 축착시켜 그 외통체(16) 내부를 수압으로 유통시켜 임펠러(15)를 회전시킬 수 있고 다공질 여과체로 오,폐수가 여과되면서 원통형 다공질 여과체의 내주연에 쌓이는 고형물질을 제거하기 위하여 작동하는 벤츄리식 역세척수 흡입노즐(24)을 타이머의 작동으로 주기적으로 전자조절밸브(23)를 개폐시키거나 또는 다공질 여과체에 고형물질이 막혀 정화통(30) 내부와의 수압차이를 이용한 차압스위치(34)를 작동시켜 고형물질을 밖으로 배출시킬 수가 있는 것이다.And the impeller 15 is condensed to the outer cylindrical shaft 11 of the one disc 10 inside the cylindrical body 1, and the impeller 15 can be rotated by flowing the inside of the outer cylinder 16 by hydraulic pressure. The venturi backwash water suction nozzle 24, which operates to remove solid matter accumulated on the inner circumference of the cylindrical porous filter medium while the wastewater is filtered through the porous filter medium, is periodically opened and closed by the timer operation. Alternatively, the solid material is blocked by the porous filter medium, and the differential pressure switch 34 using the water pressure difference with the inside of the clarification tank 30 may operate to discharge the solid material out.

이와같은 구조로 된 본 발명의 사용상태를 설명하면 오,폐수를 원통형(1)의 중심 양측으로 관통시킨 좌측유입관으로 유입시키면 내부 격판(21)에 막혀 내부 좌측관의 유출공(22)된 통해 원통형 다공질 여과체(12) 내부로 유입되고 동력모우터(2)와 체인(3)으로 연결된 스프로킷(14)에 의해 원통축(11)의 양쪽 원판(10),(10a)이 회전되면서 유입된 오,폐수가 원통형 다공질 여과체(12)로 여과되어 오,폐수내에 함유된 고형물질을 여과시킨후 외곽으로 여과된 물은 정화통(30)에 내장된 초음파발진기(31)의 초음파진동자(32)에서 발생되는 초음파에 의해 물분자가 미세화되어 물의 응집력 및 표면장력이 약화되고 오염물의 결정구조 파괴와 박테리아 등 세균의 세포막이 파괴되어 물이 정화되면서 정화통(30) 상부의 배출관(33)으로 배출되는 것으로 이때 방사되는 초음파는 물을 정화시킬 뿐만 아니라 회전되는 원통체 다공질 여과체를 진동시켜 여과체 내주연에 붙어있는 고형물질도 분리가 되어 유통관의 중간하부에 부착되어 있는 벤츄리식 역세척수 흡입노즐(24)로 흡수되어 외부로 배출시키므로서 종래처럼 다공질 여과체를 자주 교환시킬 필요가 없이 반영구적으로 사용할 수 있으므로 매우 경제적인 것이다.Referring to the use state of the present invention having such a structure, when the wastewater flows into the left inlet pipe which penetrates to both sides of the center of the cylinder 1, it is blocked by the inner diaphragm 21 and the outlet hole 22 of the inner left tube is blocked. Both discs 10 and 10a of the cylindrical shaft 11 are rotated and introduced by the sprocket 14 connected to the power motor 2 and the chain 3 through the cylindrical porous filter body 12 through the inlet. Filtered wastewater is filtered through the cylindrical porous filter body 12, and the solid material contained in the wastewater is filtered, and then the filtered water is the ultrasonic vibrator 32 of the ultrasonic oscillator 31 embedded in the clarifier 30. The water molecules are miniaturized by ultrasonic waves generated from the water) to weaken the cohesion and surface tension of the water, destroy the crystal structure of contaminants and destroy cell membranes of bacteria such as bacteria, and purify the water. The supersonic radiated at this time Not only purifies the water, but also vibrates the rotating cylindrical porous filter body so that the solid matter attached to the inner circumference of the filter medium is separated and absorbed by the venturi backwash water suction nozzle 24 attached to the lower middle of the distribution pipe. By discharging to the outside, it is very economical because it can be used semi-permanently without having to frequently change the porous filter medium as in the prior art.
