Abstract
The invention discloses a method for preparing carbon rods through the carbonizing treatment of sludge. Equipment used for preparing the carbon rods through the carbonizing treatment of the sludge is joined and assembled at an on-line sludge outlet of a sewage treatment plant, and receives the sludge for treatment, oil heat conduction drying equipment is adopted to dry the sludge until the water content is 30 percent or so, then the sludge enters a carbonization system to be carbonized and prepared into the carbon rods, the fume recovery treatment is performed at the same time, and the carbon rods with a calorific value of 2,480 kcal or so can be obtained, thereby achieving the aim of treating the sludge. The method is suitable to be matchingly used by sewage treatment plants of various cities, and realizes the on-line sludge treatment of sewage treatment. Furnace cinder after the carbon rods are combusted can be prepared into bricks on site, and can also be sold to brickyards for brickmaking to be used for buildings. The fume during the preparation of the carbon rods through the carbonizing treatment of the sludge synchronously enters a water spray tower for treatment, reaches the standard to discharge, and belongs to the clean production. The method for preparing the carbon rods through the carbonizing treatment of the sludge converts decayed, smelly and environment-harmful substances such as organic substances, protein, and fiber in the sludge into the carbon rods with high calorific value, and improves the economical value of the sludge. The high temperature produced during the combustion of the carbon rods can reduce high valence heavy metal ions in the sludge into lower valency or a metal atom state to be immobilized in furnace cinder.
Description
Technical field the present invention relates to a kind of method for making carbon rod by charing sludge.
Background technology mud derives from municipal effluent.By municipal administration planning regulations, municipal effluent must be gone into the unified discharging of pipe network, focuses on.One or more sewage works are set up by the section design in each city, and sewage is pooled to flocculation in the pond, precipitation, processed.Wherein water qualified discharge or recycling, residue mud fail to obtain to handle.
The mud color is multiple, and mud look, grey, blue grey and black etc. are arranged, paste, and water ratio 70～80% in addition, also contains various chemical medicaments, polymeric flocculant, organism, protein, multiple fiber and zoogloea.Because of the urban pipe network design of China, sewage, rainwater and industrial water drainage etc. all are pipelines, so also contain various heavy in the mud.Rot smelly (5 grades of stenches), can produce a large amount of bacteriums, communicate illness.Also contain a large amount of toxic gases in the foul smell, as hydrogen sulfide etc., harm humans life security.
Handle relatively difficulty of mud, rot to be colloid after smelly, thickness, rheological is big, and is unsuitable dry.Sticking back is difficult to the wash clean stink, and therefore handling mud seldom has successful case.
Find out that according to data present existing method for sludge treatment has seven kinds of anaerobic processes, composting process, heat drying method, burning method, natural landfill method, sanitary landfill method, unslaked lime deodorizing dry method.Because of all having cost height, suitability for industrialized production difficulty in them, the problems such as mud whereabouts unknown after heavy metal can not be handled, handle can't resolve and be stranded.
Summary of the invention the present invention adopts method for making carbon rod by charing sludge, sewage work online sludge outlet place is connected assembling making carbon rod by charing sludge equipment, receive sludge treatment, adopt oily heat conduction drying plant with drying sludge to water ratio about 30%, make rod again and enter charing system charing charcoal processing rod, reclaim flue gas simultaneously and handle, can obtain about about 2480 kilocalories carbon rod, reach and handle the mud purpose.Utilize 2/3rds carbon rods to replace coal to make the fuel of this project heat-conducting oil furnace heat treated mud simultaneously, reduced sludge treatment cost (about 45 yuan/ton).1/3rd sell burner coal in domestic garbage burning electricity generation factory or the industrial production, directly change economic benefit over to.The present invention is applicable to the supporting use in each municipal sewage plant, carries out the sewage disposal processing mud that do not roll off the production line.Slag brickmaking on the spot after the carbon rod burning also can be sold brick field brickmaking, is used for building.Flue gas in the making carbon rod by charing sludge process enters the water spray column simultaneously and handles, and qualified discharge belongs to cleaner production.Method for making carbon rod by charing sludge with organism, protein, fiber etc. in the mud rot smelly environmentally hazardous material be converted into high heating value carbon rod, improved the economic worth of mud.The high-temperature that produces during the carbon rod burning can be reduced into the valence heavy metal ions in the mud lower valency or metal atom state, is fixed in the slag.
