Abstract
It can not only use fluid material and other medium to make low-pressure high-flow cleaning, but also can implement negative pressure cleaning. Said equipment consists of working pump, cleaning pump, fluid material channel, prefilter, membrane device, pressure vacuumometer, valve and three-way pipe, etc.. The switching of the valve can make the membrane device be in working process, low-pressure high-flow cleaning process, negative-pressure cleaning process and negative pressure cleaning and back cleaning simultaneous proceeding process.
Description
The present invention relates to the improved membrane separation plant of a class, particularly a class can adopt feed liquid and other medium to carry out the cleaning of low pressure high flow rate, also can carry out negative pressure and clean the film device that also can carry out negative pressure cleaning and anti-cleaning simultaneously, belong to the separation and the apparatus technology thereof of film.
The existing film device that carries out the negative pressure cleaning of film with pump is broadly divided into four classes: the first kind is to cause positive negative pressure with the process pump suction, forms the pressure reduction of film positive and negative, makes through the liquid adverse current and cleans film (seeing United States Patent (USP) 4986918); Second class is to carry out face negative pressure high flow rate and see through the cleaning (seeing Chinese patent 96106491.9) that the liquid adverse current combines with process pump; The 3rd class is to adopt special scavenging pump, and scavenging pump inlet and operation delivery side of pump are coupled together, and conversion makes membrane module can be in the pressure journey of process pump by valve, carries out the film separable programming, can be in the suction journey of scavenging pump again, carries out the negative pressure cleaning procedure of film; The 4th class is that the negative pressure that adopts circulating pump to carry out film in charging and emission type and continous way membrane separation device is cleaned (seeing Chinese patent 96241367.4).Design in the first kind, the 3rd class, the 4th class all can't be cleaned with the negative pressure that feed liquid be carried out film, is very necessary under many circumstances and clean with the negative pressure that feed liquid is carried out film.During as the precipitation in removing medicinal liquor and Chinese medicine, general all is batch type, before a collection of being untreated, do not allow water or other medium to clean, sometimes measure very limited and see through liquid, can't be with seeing through the liquid wash cycles, undesirable again with anti-cleaning performance separately, clean with the feed liquid negative pressure in this case and negative pressure cleaning and anti-the cleaning in conjunction with just imperative.The available feed liquid of design in second class is carried out the negative pressure cleaning, but does not pass through pre-flock, as will then adding a prefilter in addition through pre-flock, causes a lot of troubles.
Existing background technology has following patent documentation by retrieval:
