Background technology
At present, the desulfurization of magnesium method is the conventional method of flue gas desulfurization, and the desulfurization side product magnesium sulfite that the desulfurization of magnesium method produces must be processed in time, otherwise can cause secondary pollution.Magnesium method desulfurizing byproduct is produced in the technique of epsom salt and liquid sulfur dioxide, and it is impure saturated solution of magnesium sulfate that reaction finishes rear system, and temperature is 75 DEG C ± 5 DEG C, under condition of different temperatures, and the different solubility of magnesium sulfate in water, easily crystallization.When magnesium sulfate filters, along with the reduction of temperature, magnesium sulfate meeting crystallization, causes filter to stop up, and after filtration finishes, due to the remaining a certain amount of Adlerika of meeting on filter material in filter, after temperature reduces, can cause equally filter obstruction.
Mono-kind of Chinese patent ZL200510086387.8 is for filtering the metal powder sintered filter element hot-water filter of saturated solution of magnesium sulfate, adopt metal powder sintered filter element as filter material, the even aperture distribution of metal powder sintered filter element, filtering accuracy is high, the size ratio containing in flue gas desulfurization byproduct magnesium sulfite can be removed compared with small impurities, chuck heating, insulation construction can ensure not have and cause the problem of Crystallization Plugging filter core to produce because temperature reduces in saturated solution of magnesium sulfate filter process, but, the rate of filtration is slow, after finishing, filtration needs with a large amount of water, filter to be cleaned, affect manufacturing schedule.Need to solve filter in saturated solution of magnesium sulfate filter process stops up and the slow problem of the rate of filtration for this reason.
Summary of the invention
The purpose of this utility model is to provide a kind of plate and frame filter press for saturated solution of magnesium sulfate high temperature filtration, solves filter in saturated solution of magnesium sulfate filter process and stops up and the slow problem of the rate of filtration.
The technical solution of the utility model is following realization, a kind of plate and frame filter press for saturated solution of magnesium sulfate high temperature filtration, formed by frame and staggered polylith filter plate, filter frame and the mechanical clamping device being assembled in frame, on the surface of filter plate and filter frame with ups and downs filtrate channel, filter plate, filter frame both sides have identical opening, the mutual UNICOM of opening on all filter plates, the transfer passage of formation slurries, compressed air and flushing water; Filter frame is connected with feed pipe by opening, and feed pipe is provided with compressed air hose and wash tub pipe, forms charging, the rinse-system of plate and frame filter press; Below each filter plate, be provided with discharge opening and discharge nozzle, discharge nozzle is communicated on discharge opening, and the bottom of discharge nozzle is provided with filtrate receiver, and as the interim receiving system of filtrate, the bottom of filtrate receiver is provided with discharging tube.Plate and frame filter press is fixed in frame, and power set are the mechanical clamping device of frame rear side.
The utlity model has following advantage: plate and frame filter press has the advantages such as the rate of filtration is fast, filter area is adjustable, treating capacity is large, can meet the requirement of saturated solution of magnesium sulfate high temperature filtration.The filter cake that can utilize compressed air that filter process is finished in rear plate and frame filter press dries up, and reduces material waste, is convenient to filter cake cleaning.After filter cake is cleaned out, can plate and frame filter press thoroughly be cleaned or be soaked water, carrying out sufficient preparation for next pressure-filtering process, avoiding magnesium sulfate at plate and frame filter press intercrystalline blocking device.
