Description
Technical field
The utility model relates to a kind of filter press.
Background technology
Filter press is a kind of conventional solid-liquid separating equipment, is just applied to Chemical Manufacture in 18 beginnings of the century, is still widely used in chemical industry, pharmacy, metallurgy, dyestuff, food so far, brewages, pottery and the industry such as environmental protection.As a kind of dehydration equipment of maturation, filter press is widely applied to field of Environment Protection, becomes the visual plant of sewage sludge process.
General domestic sludge processing method adopts the mechanical dehydration adding high molecular polymer, usually first through modifier treatment, modified have multiple method, has ermal physics method, as pyrohydrolysis, hydro-thermal mummification, moist oxidation etc., there is Physical, as ultrasonic wave, microwave etc., maximum is chemical method, by adding some inorganic chemistry salt (medicament), can play and change mud molecule charge polarity, increasing pellet pores, improve the effects such as press filtration characteristic.Also the most cheap the most general technology is all the modified combination adding filter press process of sludge chemical in the market.
Mechanical sludge dewatering mainly removes the capillary water between mud granule, and the moisture percentage in sewage sludge after standard machinery dehydration is often 65%-80%, in mud cake shape.When adopting Sludge landfill, sludge dewatering can greatly reduce mud accumulation place, save in transportation the expense occurred, when carrying out compost treatment to mud, sludge dewatering can ensure that compost carries out smoothly (in composting process, General Requirements mud has lower moisture content), if carry out sludge incineration, focus on, dewatering rate height can greatly reduce thermal energy consumption, the disposal cost of harm reduction thing.
Mechanical dewatering equipment mainly contains belt filter press, plate and frame filter press and sleeping spiral shell sedimentation centrifuge in the past, now conventional chamber-type press filter, vertical hydraulic filter press, diaphragm machine and high pressure board and frame machine.
Chamber-type press filter grows up after the sixties in 20th century.Be characterized in that filter pressure is high, unit filter area is large, and filter cake liquid content is low, and corrosion resistance is good, and filter plate is lightweight, and good springiness is corrosion-resistant, wide adaptability, and running expense is low, can realize that multiple stage is worked continuously, online control.Modern filter press is main mainly with van-type.
Chamber-type press filter operation principle forms one group of filter chamber by the filter plate be alternately arranged and filter frame, and there is groove on the surface of filter plate, and filter plate both sides are recessed, and every two pieces of filter plates synthesize a railway carriage or compartment shape filter chamber, and there are pit and boss in the surface of filter plate, in order to supporting filter cloth.The corner of filter frame and filter plate there is through hole, forms complete passage after assembling, suspension, washings and extraction filtrate can be passed into.The each jug rest in filter plate both sides, on crossbeam, compresses filter frame and filter plate by hold down gag.Filter cloth between plate, frame plays gasket seal.
Under the pressure effect of dehvery pump, send each filter chamber to, by filter medium, by solid and fluid separation applications by needing the feed liquid of filtering.Filter cloth forms filter residue, until be full of filter chamber to form filter cake.Filtrate, through filter cloth and along filter plate trench flow to sheet frame corner passage, is concentrated and is discharged.Filter complete, cleaning can be passed into and wash water washing filter residue.After washing, sometimes also pass into compressed air, remove remaining cleaning solution.Open filter press removal after filtration terminates and store the filter cake be between adjacent two filter plates, cleaning filter cloth, compression filter frame and filter plate start subsequent work circulation again.
Plate and frame filter press suspension that is large for filter residue compressibility or near incompression can be suitable for.The concentration of solid particles of the suspension be applicable to is generally less than 10%, and operating pressure is generally 0.3 ~ 0.6 MPa, and special reaches 3 MPas or higher.Filter area can increase and decrease with sheet frame number used.Sheet frame is generally square, and the interior length of side of filter frame is 200 ~ 2000 millimeters, and frame is thick is 16 ~ 80 millimeters, and filter area is 0.5 ~ 1200 square metre.The modes such as plate and frame hand power screw, electric screw and hydraulic pressure compress.The material manufactures such as plate and frame timber, cast iron, cast steel, stainless steel, polypropylene and rubber.
But, sludge components is complicated, relative density is less, particle is thinner, and colloidal state situation often, determine the feature that it not easily dewaters, current filter press by when needing the feed liquid of filtering to send each filter chamber to, needs to continue for a long time to pump under the pressure effect of dehvery pump, just filtrate can be sloughed, be pressed into filter cake, required time is very long, consumes the energy larger.In the process of filtering, hold down gag also needs to compress filter frame and filter plate all the time, has more increased the weight of the consumption of the energy.How solving filter press length consuming time, shortcoming that energy consumption is large, is the key subjects that industry faces.
