本発明はセラミックフィルターの目詰りを除去するセラ
ミックフィルターの一過装置およびその洗浄方法に関す

洗するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a ceramic filter filtration device for removing clogging of a ceramic filter and a method for cleaning the same. It is used for backwashing.
従来からの一過方法（ダイレクトフロー）は、−過しよ
うとする原液をフィルターで仕切る構造になっている。The conventional filtration method (direct flow) has a structure in which the undiluted solution to be filtrated is separated by a filter.
このため原液中の微粒子等はフィルター表面に蓄積して
短時間に目詰りしていた。For this reason, fine particles in the stock solution accumulate on the filter surface and become clogged in a short period of time.

低く、実際に取出せる有効−過量を増加させることは困
難である。また、逆洗に使用するポンプは比較的高圧の
ものが必要であり、これが装置のコストを高価にすると
いう欠点もあった。In recent years, a filtration method using cloth 70 has been adopted as a more efficient method than this one-time method, but the clogging phenomenon progresses over time, reducing the exit rate. There is. A common method for removing this clogging is to backwash the filter by causing the filtrate to flow backwards. There is a method of washing away particulates that have clogged rMK, but this method uses a large amount of filtrate, so the effective amount of filtration decreases, and the recovery rate of the filter is low even though a large amount of filtrate is used. It is difficult to increase the effective excess that can be extracted. Furthermore, the pump used for backwashing requires a relatively high-pressure pump, which also has the drawback of increasing the cost of the device.
本発明は従来のように濾過液を使用せず、安価で効果的

。The present invention does not use a filtrate as in the past, but instead uses compressed air and a filtrate, which is inexpensive and effective, for backwashing.
以下本発明を図面について訳明する。 The present invention will be explained below with reference to the drawings.

している。A ceramic filter 1 is housed inside a casing 2. The ceramic filter 1 is formed by molding alumina or the like into a cylindrical shape, and has seven flange 8 attached to the end face thereof, and the flange 8 #:l: is attached in close contact with the casing 2. As described above, the undiluted solution passes through the ceramic filter 1 from the undiluted solution inlet to the undiluted solution outlet and circulates by a transport pump (not shown).

で回収される。The filtration pressure is adjusted by adjusting the valve 3 provided at the stock solution outlet.
This is confirmed by adjusting the pressure of pressure gauges 4 and 5. The filtrate that has passed through the ceramic filter 1 fills a casing 2, overflows from a valve #J6 (for example, a magnetic valve) attached to the casing 2, and is collected outside.

圧ヘッド９を設けるとよい。A valve mechanism 7 (for example, a solenoid valve, etc.) attached to the casing 2 blows compressed air into the inside of the casing 2.
-K, which connects the casing 2 with the excess liquid discharge port and the compressed air blowing port, uses the same cylinder, and the upper part is formed into two forks as shown in FIG. 1, and the valve mechanism 6 is installed in one of them. Although the valve mechanism 7 may be attached to the other one, as shown in FIG. 2, the trap and casing 2 may be provided with separate cylinders and each cylinder may be provided with a valve mechanism 6.7. However, if a compressed air outlet is provided below, a pressurizing head 9 may be provided.

取り出せる。In order to carry out the filtrate collection process with the transit device thus formed, the valve mechanism 6 is opened, the valve mechanism 7 is closed, and the valve 3 provided on the stock solution outlet side is adjusted to allow the stock solution to flow through the pipe. The filtrate that has passed through the ceramic filter 1 fills the casing 2, and after it is filled, it can be taken out of the casing 2 through the valve mechanism 6.

時間のサイクルで行うと効果的である。K, who is in charge of backwashing, closes the valve mechanism 6 and opens the valve mechanism 7 to blow out compressed air for a short period of time. - The excess liquid is instantly applied with a large pressure and flows backwards, causing the filter 1 to be washed away. Wash. Due to this action, particles that adhere to the inner wall of the filter 1 and become clogged float to the surface, and the raw solution transport pump continues to operate during the backwashing process to flush the floating particles out of the filter 1. I can put it out. Backwashing is effective when performed in relatively short cycles.

[Effects of the Invention] According to the device and method of the present invention, it is possible to use 3 more credits than the amount of one-off when using a conventionally used pump, and the amount of filter water is increased by 3. The larger the size, the greater the effect. - If it is not desired to directly introduce compressed nitrogen into the effluent, the same effect can be obtained by using an IC such as a cylinder or diaphragm.
またセラミックフィルターは耐薬品性にすぐれているの

以上セラミックフィルターを回復させることができる。Additionally, since ceramic filters have excellent chemical resistance, it is recommended to use chemical cleaning in conjunction with cleaning to remove clogs that cannot be removed by backwashing. For example, cleaning with 10% HCt for 1 hour can restore more than 95 ceramic filters.
