Abstract
The utility model relates to a paper-making black liquor deep-layer adsorbing filter used in the process of treating the paper-making black liquor. The utility model is mainly composed of a barrel body and filtering materials. The utility model is characterized in that the upper end and the lower end of the barrel body are provided with a liquor inlet pipe and a liquor outlet pipe; the filtering materials can be arranged between a pressing plate at the upper end of the inner part of the barrel body and a supporting plate at the lower end of the inner part of the barrel body. The black liquor can enter the barrel body from the liquor inlet pipe; the filtering medium can adsorb a large number of coloring substances in the waste liquor so as to reduce the COD content. Compared with the prior art, the utility model has the advantages of simple equipment, easy manufacture, and small occupation area. The utility model can select the barrel body with different diameters according to the requirement of quantity of treated water. Because the adsorption medium can use the coal slag or the fly ash of the boiler in the paper mill, the utility model not only can make the water quality of the waste water conform to the state standard of waste water discharge, but also can reach the comprehensive treating purpose that the waste substances can be used to treat the waste water. Because the utility model has characteristics of low cost, safe, and long service life, the utility model has wide adaptation range.
Description
The utility model relates to a kind of black liquid deep layer adsorption filter that is used for the administration of papermaking black liquid process, mainly is made up of cylindrical shell and filtrate.
Paper-making pulping process is the necessary technical process of papermaking, will produce a large amount of paper-making pulping black liquors in this implementation of processes, contains organic matters such as a large amount of celluloses, lignin and carbohydrate in this black liquor.If this type of material is unprocessed or deal with direct discharging improperly, with serious environment pollution.Mainly be at present adopt acid out, alkali is analysed and physical-chemical processing mode such as flocculation sediment, but still has a large amount of suspended matters and coloring matter in the water, COD and BOD (chemical oxygen consumption and biological oxygen demand (BOD)) still fail to meet the water quality discharge standard of national regulation.Existing method for subsequent processing be with this kind waste liquid with after a large amount of papermaking stage casing discharge waters and bleaching water mix, in addition various biochemical process processing again.The defective of this method for subsequent processing is that floor space is big, investment and operating cost height.
For fear of the deficiencies in the prior art part, the utility model proposes a kind of deep layer adsorption filtration principle of utilizing, a large amount of suspended matter and coloring matter in the Processing Paper Wastewater, the black liquid deep layer adsorption filter that COD and BOD can be up to state standards.
Technological thought of the present utility model is to through acid out, alkali is analysed and physical-chemical such as flocculation sediment was handled black liquid, the adsorption filtration of employing deep layer.It is characterized in that: the upper and lower end design end cover (3) and (13) of cylindrical shell (7), the center design feed tube (1) of upper end cover (3), the center design drain pipe (14) of bottom end cover (13); Design pressing plate (5) in upper end in the cylindrical shell (7), design gripper shoe (10) in lower end is placed filtrate (8) between pressing plate (5) and the gripper shoe (10).Black liquor is entered in the cylindrical shell (7) by feed tube (1), and through being compacted in the process of filtrate (8), filter media has been adsorbed coloring matters a large amount of in the waste liquid, greatly reduces COD content.
For the black liquor that desire is handled can evenly pass through filtrate (8), improve the efficient of filtering, at the lower end of feed tube (1) design liquid distribution plate (2).
Filter cloth (6) and filter cloth (9) in that filtrate (8) upper/lower terminal is installed can further improve filter effect.
Filtrate (8) can adopt boiler cinder or flyash.

The utility model will be in conjunction with the embodiments (accompanying drawing) be further described:
Cylindrical shell in the present embodiment (7) adopts ordinary carbon steel, and diameter is φ 800, and long is 1500mm; Cylindrical shell (7) is connected with (13) quick opening structure by the profile of tooth interlock with the end cover (3) of upper and lower end, and middle with seal (4) and (12) sealing, ordinary carbon steel is adopted in end cover (3) and (13); The drain pipe (14) at the feed tube (1) at upper end cover (3) center and bottom end cover (13) center also adopts ordinary carbon steel, and caliber is φ 57; Gripper shoe (10) is placed on the bracing ring (11), and bracing ring (11) is welded in the lower end in the cylindrical shell (7); It is the wool felt of 2mm that filter cloth (6) and filter cloth (9) are selected thickness for use, and filter cloth (9) is layered on the gripper shoe (10); Filtrate (8) adopts 40 orders～200 purpose boiler cinders, is deposited on the filter cloth (9).The upper end of filtrate (8) presses filter cloth (6), and compresses with pressing plate (5); On the pressing plate (5), to adopt thickness be 10～20mm for the liquid distribution plate (2) of feed tube (1) lower end, metallic porous sheet.Black liquor is entered in the cylindrical shell (7) by feed tube (1), and through being compacted in the process of filtrate (8), filter medium has adsorbed coloring matters a large amount of in the waste liquid, greatly reduces COD content.
The utility model advantage compared to existing technology is: equipment is simple, easy to manufacture, takes up an area few. According to processing water The needs of amount are selected different barrel diameters. Because adsorbing medium can be selected Boiler Cinder Surveying or the fine coal in paper mill itself Ash not only makes it become the water quality that meets discharging standards, and reaches the comprehensive regulation of the treatment of wastes with processes of wastes against one another. Because this dress It is low to put cost, safe and reliable, and long service life has the characteristics of wide accommodation.
