Description
Technical Field
The utility model relates to an automatic control system of ultrafiltration water purification equipment.
Background
The retention of solutes by ultrafiltration membranes is considered to be mainly a mechanical sieving effect, i.e. ultrafiltration membranes have pores of a certain size and shape, solvents and small-molecule solutes permeate the membrane under the action of pressure, while large-molecule solutes are retained by the membrane. The pore size range of the ultrafiltration membrane is 0.01-0.1 mu m, and the ultrafiltration membrane can intercept particles, colloids, bacteria, macromolecular organic matters and partial viruses in water, but cannot intercept inorganic ions and micromolecular substances. Ultrafiltration has two filtration modes, terminal filtration and cross-flow filtration, and a terminal filtration mode is generally adopted. The final filtration is that the water to be treated completely permeates the membrane under the action of pressure, and the particles in the water are intercepted by the membrane. Because the trapped impurities are all deposited on the membrane surface, the flux of the end filtration is reduced rapidly, the membrane is easy to block, and the back flushing is needed periodically to recover the flux.
The traditional ultrafiltration water purification equipment is usually controlled by a PLC (programmable logic controller), the backwashing time is controlled according to the pressure difference of the water inlet end and the water outlet end of an ultrafiltration membrane group, and an electric valve is controlled to realize the normal filtration and backwashing processes. However, the price of the PLC equipment is very high, one valve needs to be controlled by setting an output point of the PLC, and the process is quite complicated. When being applied to small-size ultrafiltration water purification unit, because need valve quantity many, the delivery point design is complicated, needs cost of labor and equipment cost height, is unfavorable for technical popularization, and the suitability is poor.
