Abstract
The present invention relates to a shutter type activated carbon activating furnace and an activating method. The present invention causes activated carbon to lower energy consumption and improve efficiency during production. A furnace core is made of one-side shutter type bricks or dual-side shutter-type bricks, and the bricks are arranged in the shape of a plurality of shutters; a shutter type slope of an activating passage causes raw materials to be continually turned and mixed to be sufficiently activated. The activating furnace uses combustible gas as fuel, and the combustible gas and steam are directly mixed and heated and are used as activating media. The present invention can recover and reuse waste gas produced during activation.
Description
The invention relates to activation equipment and the activation method of making gac.Products obtained therefrom uses as sorbent material and discoloring agent aspect industry such as food, medicine, chemical industry, national defence and environmental protection widely.
Activation furnace is the key equipment in the Activated Carbon Production.Activation furnace has several type of furnaces such as Si Lepu stove, swash plate stove at present." wood pyrolysis technology " book introduction that China Forest press publishes May nineteen eighty-three, there is following shortcoming in normally used Si Lepu stove: 1, complex structure.Form by heating half stove, cooling half stove and two regenerative furnaces, constitute by 32 kinds of Idiotype refractory brick in the stove.2, the water vapor of Shi Yonging produces by special-purpose steam oven, and the thermal recovery regenerative furnace of crossing of water vapor heats, and needs the equipment and the Controlling System of regular blocked operation, the fluctuation of superheated vapour temperature generating period.3, the gas road of level, semicircular in shape, the powder that is flown upward easily stops up.And number of patent application is the swash plate stove of CN85103470, adopts the inner flue heating, promptly adopts refractory brick interlayer indirect heating, and thermo-efficiency is low, and the activation road is alternate in twos with inner flue, makes body of heater huge, complex structure.Secondly because of operating under negative pressure, furnace roof contacts with the activation raw material layer with the furnace bottom inhaled air, causes raw material and gac fractional combustion, reduces the yield and the quality of gac, and the horizontal gas road of swash plate stove is also blocked easily in addition, needs regular blowing out cleaning.
The purpose of this invention is to provide gac manufacturing and regenerated activation furnace and corresponding activation method thereof.Simplify the Si Lepu stove, both activatable particles raw materials also can activate the raw material of entrained powder, avoid the gas road to stop up, prevent that raw material or gac from directly contacting the generation fractional combustion with air, improve the yield and the quality of gac, improve heat energy utilization rate and production efficiency.
According to the activation equipment that the invention provides gac, this equipment is vertical activation furnace, and its vertical combustion chamber is arranged in order as a plurality of window shutters and forms, and window shutter is that one-sided or bilateral blinds brick is arranged above and below and constitutes by polylith.Link up each other between activated bath and groove.The stove both sides are provided with several combustion chambers, and the combustion chamber of close furnace roof portion and furnace bottom is a gas combustion chamber.Activated media adopts the direct Hybrid Heating of burning gas.Be separated into plurality of sections by dividing plate from top to bottom between the groove of one-sided blinds tile stove core, communicate with the combustion chamber between every groove of every section, the furnace wall of each combustion chamber of activation section is provided with gray-drawing port.Furnace air keeps malleation, and discharger is equipped with the device that hinders air admission.
The present invention simultaneously provides activation method with regard to this activation furnace.To activation section, in activated bath, gravitate moves down raw material through preheating section, is subjected to the effect of blinds brick, constantly stirs mixedly, and carries out heat exchange and priming reaction by flowing to the activated media that comes between groove, obtains gac through cooling section and discharge port then.
Activation furnace of the present invention, structure are very simple, have improved the activation efficiency of body of heater, because the combustion gas heating, protection raw material and gac are avoided air and watered mistake; the yield height, quality is good, the energy utilization rate height, the combustion chamber permeability is good; the gas road is difficult for stopping up, and pollution-free, technology is reliable, and is easy and simple to handle.
