Description
Technical field
The present invention relates to technical field of water treatment equipment, particularly a kind of polytetrafluoroethylene (PTFE) cartridge type Flat Membrane distiller.
Background technology
Membrane Materials is a kind of employing dewatering microporous film, the membrane separating process being mass transfer driving force with film both sides steam pressure difference.Under the driving of the steam pressure difference of microporous hydrophobic membrane both sides, water vapour is condensed into liquid separation process again after being passed hydrophobic membrane by the Yuan Shui side of heating.Due to the hydrophobicity of film, only have water vapour can through fenestra, former water and the Nonvolatile solute be dissolved in wherein cannot pass fenestra, so Membrane Materials procedural theory can realize 100% remove to ion, large molecule, colloid, cell and other non-volatile matter.Microporous hydrophobic membrane plays the support shielding action between two-phase in Membrane Materials process.In the process of Membrane Materials, heat and mass transfer two kinds of processes occur, temperature difference polarization also can produce with temperature difference polarization phenomena simultaneously simultaneously, thus produces adverse influence to the process of Membrane Materials.The operating temperature of Membrane Materials process is lower than traditional still-process, and operating pressure is lower than traditional membrane separating process; Lower to the mechanical property requirements of film; Compared with traditional still-process, the vapor space significantly reduces.The assembly of Membrane Materials can be designed to recovery of latent heat form, and has the flexibility being formed large-scale production system with efficient small-sized membrane module.This process can the high fortified aqueous of concentration for the treatment of, if solute is the material of easy crystallization, solution can be concentrated to hypersaturated state and realize Membrane Materials crystallization, it is the membrane process uniquely directly isolating crystallized product at present from solution, as long as and film both sides maintain the suitable temperature difference, this process just can be carried out, and can utilize the cheap energy such as solar energy, underground heat, hot spring, waste heat of plant and warm industrial wastewater.It is low that film distillation technology has operating pressure, have the salt rejection rate that can obtain 99. 99 % and under excellent operation condition higher than the water flux of counter-infiltration, show it and substitute (extensive pure water preparation) or supplementary technology as reverse osmosis technology.
Current Membrane Materials device mainly contains board-like dull and stereotyped Membrane Materials device, cartridge type film silk group distiller, submerged film silk group distiller.And board-like dull and stereotyped Membrane Materials device needs shaper, the large Heavy Weight of volume, structure is stacked inconvenience repair and replacement, be difficult to meet industrialization use, cartridge type film silk group distiller is very high to hydrophobic membrane silk throughput requirements used, can only accomplish now that the aperture rate flux of 50% is too little and film silk makes not easily volume production, there is such problem in submerged film silk group distiller too.
