Abstract
The invention provides a cleaning method for a membrane, which is used for cleaning the membrane by adopting continuous negative pressure pulse. Two liquid communicating ports of a membrane assembly are respectively connected with an inlet of an eccentric pump, a cleaning liquid tank and a liquid circulating pipeline through valves, and the continuous negative pressure pulse cleaning of the membrane is realized through rapid closing and opening of an electric valve of the cleaning liquid tank.
Description
Technical field
The present invention relates to a kind of cleaning method of film, particularly a kind of method that adopts the continous way underbalance pulse to clean film belongs to the separation and the apparatus technology thereof of film.
Background technology
The negative-pressure pulsed washing method of existing film is that two feed liquid communication port with membrane module connect vacuum plant by valve respectively, cleans liquid bath and feed liquid circulation line, cleans with the underbalance pulse that connects the rapidly opened and closed realization film that cleans the liquid bath valve.In the cleaning process of film, be evacuated to-0.01～-1.0Mpa, open suddenly and connect the valve that cleans liquid bath and form underbalance pulse, when repeating this step, all must be evacuated to-0.01 earlier at every turn～-1.0Mpa (seeing Chinese patent 00136794.3).Therefore, this negative-pressure pulsed washing method is a discontinuous, and operation is trouble comparatively, is difficult for realizing control automatically.
Summary of the invention
The object of the present invention is to provide a kind of method that adopts the continous way underbalance pulse to clean film.
The present invention connects the centrifugal pump inlet by valve respectively with two feed liquid communication port of membrane module, cleans liquid bath and feed liquid circulation line, cleans with the continous way underbalance pulse that connects the rapidly opened and closed realization film that cleans the liquid bath electrically operated valve.
Description of drawings
Fig. 1 is a continous way negative-pressure pulsed washing method schematic diagram of the present invention.Wherein: the 1, the 3,4,5, the 13rd, valve, the 2nd, electrically operated valve, the 6th, centrifugal pump, 7, the 8th, pressure vacuum gauge, the 9th cleans liquid bath, the 10th, membrane module, 11, the 12nd, feed liquid communication port, the 14th sees through liquid bath.
Embodiment
Below the present invention is elaborated:
A feed liquid communication port 11 of membrane module 10 connects the feed liquid circulation line by valve 4, the inlet that connects centrifugal pump 6 by valve 5, the outlet of centrifugal pump 6 is linked through pipeline and is cleaned liquid bath 9, another feed liquid communication port 12 of membrane module 10 connects the feed liquid circulation line by valve 1, the inlet that connects centrifugal pump 6 by electrically operated valve 2, connect cleaning liquid bath 9 by valve 3, the liquid outlet that sees through of membrane module 10 is linked through liquid bath 14 by valve 13.Feed liquid communication port 11 is connected with pressure vacuum gauge 7, and feed liquid communication port 12 is connected with pressure vacuum gauge 8.As shown in Figure 1.
Method of operating is as follows:
(1) opens and connect the centrifugal pump inlet valve, close the liquid communication port valve that connects material;
(2) liquid to be cleaned is full of pipeline formation circulation;
(3) open or close the electrically operated valve that connects the cleaning liquid bath suddenly;
(4) repeating step 3, by the duration that automaton sets blanking time that electrically operated valve opens or close and unlatching or cuts out, clean with the continous way underbalance pulse that connects the rapidly opened and closed realization film that cleans the liquid bath electrically operated valve.
Embodiment 1:
Valve-off 1,2,4,13 during cleaning, Open valve 3,5, start centrifugal pump 6, liquid to be cleaned is full of pipeline and forms circulation time, open electrically operated valve fast and close after 2,0.2～120 seconds, repeat above step, set the blanking time of electrically operated valve 2 unlatchings and the duration of unlatching by automaton, thereby realize that the continous way underbalance pulse cleans.
Embodiment 2:
Valve-off 1,4,13 during cleaning, Open valve 2,3,5, start centrifugal pump 6, liquid to be cleaned is full of pipeline and forms circulation time, the quick closedown electrically operated valve was opened after 2,0.2～120 seconds, repeated above step, set blanking time that electrically operated valve 2 closes and the duration of closing by automaton, thereby realize that the continous way underbalance pulse cleans.
