Abstract
The utility model relates to a ceramic-membrane back-flushing device which belongs to the mechanical field. The ceramic-membrane back-flushing device aims at adopting a back-flushing method to carry out the cleaning, the recovery and the regeneration to the membrane flux of a ceramic-membrane device. The ceramic-membrane back-flushing device is provided with a tee on an outlet after the membrane is cleaned, the tee is connected with pipelines which are respectively connected with a permeated liquid tank by a permeated liquid inlet and a permeated liquid outlet, back-flushing pressure gauges are arranged on the pipelines, a permeated liquid tank bottom valve and a back-flushing pump are arranged on the pipeline of the permeated liquid inlet, and a back-flushing pressure-equalizing gauge is arranged on the permeated liquid outlet. The cleaning technique of the ceramic-membrane back-flushing device can carry through the recovery and the regeneration of the ceramic-membrane flux online on the basis of the commonly traditional cleaning method when the power-off of the device is not required.
Description
Technical field:
The utility model belongs to mechanical field.
Background technology:
At present, the ceramic membrane production equipment is in order to recover membrane flux, generally all adopt traditional cleaning method, also cry and just washing method, (both added acid or added alkali or other cleaning agent in pure water, device systems is during as ordinary production, and the ON cycle pump carries out wash cycles, different is to close the penetrating fluid outlet valve; Every about 20 minutes, open the penetrating fluid outlet valve, observe the permeate flow meter, detect membrane flux, recover) until membrane flux.There is following problem in traditional cleaning method:
1, the flux resume speed is slow, the energy consumption height;
2, flux recovers not thorough
3, can not onlinely carry out the recovery regeneration of ceramic membrane flux
Summary of the invention:
The purpose of this utility model is to adopt a kind of backwash mode ceramic membrane equipment membrane flux to be cleaned the back purge system that recovers regeneration.
The utility model is on the purified liquor outlet of ceramic film component feed end threeway to be installed, threeway is connected with pipeline, outlet is connected with the backwash flow container pipeline with counter-flushing liquid by the counter-flushing liquid import respectively, the backwashing pressure table is installed on pipeline, counter-flushing liquid bottom valve and backwashing pump are installed on the pipeline of counter-flushing liquid import, in the counter-flushing liquid outlet, the backwashing pressure balance sheet are installed.
The utility model cleaning technique increases many advantages again on general conventional clean method basis:
1, equipment need not shut down, and can onlinely carry out the recovery regeneration of ceramic membrane flux.
2, faster, more thorough than former cleaning method to membrane flux recovery regeneration, can also save the energy and cleaning agent consumption.
Not only can select single component to carry out backwash recovery regeneration when 3, equipment moves, can also carry out in batches, divide into groups to carry out backwash to membrane module and recover regeneration (but necessary parallel connection divides group selection).
4, sustainablely provide the enough backwashing pressure and backwash water yields.
5, in system, when material is concentrated to a certain degree when certain multiple (or), need add the water dialysis, open backwashing pump this moment, so both reached the purpose that adds the water dialysis, and the while has been realized the regeneration that is restored of ceramic membrane flux again in the shortest time.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
The utility model increases a device and finishes on the basis of existing ceramic membrane flusher, it mainly is that threeway 1 is installed on the purified liquor outlet of ceramic film component feed end, threeway 1 is connected with pipeline 2, pipeline 2 is connected with backwash flow container 8 by counter-flushing liquid import 6 and counter-flushing liquid outlet 9 respectively, backwashing pressure table 3 is installed on pipeline 2, counter-flushing liquid bottom valve 7 and backwashing pump 5 are installed on the pipeline of counter-flushing liquid import 6, in counter-flushing liquid outlet 9, backwashing pressure balance sheet 4 are installed.
The course of work is:
Open counter-flushing liquid bottom valve 7, backwashing pump 5 is started working, flushing liquor in the backwash flow container 8 is pumped, measure counter-flushing liquid by backwashing pressure table 3 and entering the pressure of ceramic film component, pressure is excessive, unnecessary counter-flushing liquid is got back in the recoil cleaning of evaporator 8 by counter-flushing liquid outlet 9, and the counter-flushing liquid that ceramic film component cleans is entered into the existing main circulatory system of cleaning after ceramic film component is carried out backwash.
