Description

A kind of vertical activation furnace of self-produced water vapour preparing active carbon

First, technical field

The equipment that this utility model is related to preparing active carbon, especially a kind of vertical activation of self-produced water vapour preparing active carbon Stove.

2nd, background technology

At present, produce the method for activated carbon mainly to have physical activation method and phosphoric acid that water vapour makees activator is activator Two kinds of chemical activation method, either which kind of method preparing active carbon, activation furnace is all the equipment of most critical, and the structure of activation furnace is shadow Ring the determiner of quality of activated carbon and yield.The activation furnace of steam physical method preparing active carbon has vertical Slapple activating furnace With swash plate moving bed activation furnace and horizontal rotary furnace etc., the operation of Slapple activating furnace needs to be equipped with steam boiler, and it has a left side Right two and half stoves and two regenerator, be preheated in turn and handover operation, complex structure to steam, and operating technology is required Height, investment is big；The quarl species of swash plate moving bed activation furnace is more, and the customization of refractory brick and the building construction of activation furnace are difficult Degree is larger, and the quarl having is easily damaged, and the service life of stove is not long, in addition, activator water vapour is without pre- Heat is just passed directly into combustor, causes the reduction of furnace temperature, in addition, raw material is less with the contact surface of water vapour, activation effect is paid no attention to Think.Swash plate moving bed activation furnace cross section is square structure, is heated mainly by the combustor of both sides, the activation road temperature at stove center Degree it is lower than close combustor, stove is bigger, and furnace temperature is more uneven, and activation furnace is unfit to do too big, thus activation yield compared with It is little.If Physical activation furnace need not be equipped with steam boiler, investment can be saved more, and floor space can be less, if steam is being lived Change furnace interior preheated after again with raw material haptoreaction, activation effect will be more preferable.Based on above-mentioned background and imagination, this practicality A kind of vertical activation furnace of self-produced water vapour preparing active carbon of new design.

3rd, the content of the invention

A kind of vertical activation furnace of self-produced water vapour preparing active carbon of the present utility model, its external form is twelve edge Shape, is orthohexagonal cavity in the section that is internally formed of stove, and the waste heat pot for making thermal source using activation tail gas is arranged in cavity The self-produced water vapour of stove；The loop configuration arrangement hexagonal in two rows of the activation tube of reverse frustoconic, surrounding is lived inside and outside activation furnace The both sides for changing pipe arrange multiple plus hot chamber.The vertical activation furnace mainly by activation tail gas flue (1), drawing mechanism (2), go out Expects pipe (3), support column (4), activation tube support baseboard (5), reverse frustoconic activation tube (6), combustor (7), fuel burner nozzle (8), Combustor dividing plate (9), feed bin (10), sealed cistern (11), feed bin lid (12), waste heat boiler (13), steam pipe coil (14), combustion gas In pipe (15), heat-resistant layer (16), activation furnace exterior wall (17), annular steam distributor pipe (18), steam pipe (19), high-temperature gas water conservancy diversion Heart pipe (20), truncated cone-shaped passage (21), high-temperature gas water conservancy diversion bottom pipe (22) and annular activation tube cover plate (23) are constituted.Activation Road is piled up by more piece reverse frustoconic activation tube (6) and is formed, and combustor (7) is arranged between activation tube and heat-resistant layer.By reverse frustoconic The activation road that activation tube (6) is constituted with truncated cone-shaped passage (21) and high-temperature gas water conservancy diversion central canal (20) is in differing heights position Cross section in the loop configuration that differs in size, raw material curvilinear motion from top to down in activation road, make material constantly Change the contact surface of location, continuous feed change and activation tube in activation road.In activation offgas outlet and activation tail Waste heat boiler is set between gas flue, is produced steam using the waste-heat water of activation tail gas and is made activator, from waste heat boiler Water vapour through being arranged on activation tail gas flue in steam pipe coil preheating after be passed into each activation tube hub steam pipe (19) in, Jing often saves the annular steam of activation tube after further being heated by the high-temperature gas in high-temperature gas water conservancy diversion central canal (20) During distributor pipe (18) is uniformly distributed to raw material, the priming reaction effect of steam and raw material is improved.Vertical activation of the present invention The activation tube of stove presses the loop configuration arrangement of hexagon, can arrange more activation tube, and the yield of preparing active carbon is larger.

The furnace roof that the raw material elevator of preparing active carbon is lifted to activation furnace is added in feed bin (10), and raw material exists from top to bottom Reverse frustoconic activation tube is progressively heated in (6).Annular is set between the middle epimere low-temperature space of activation furnace, upper and lower two sections activation tube Cover plate (23), makes tight between upper and lower two sections activation tube, the fuel gas produced when raw material is heated be forced from volatilization gas to lead Discharge orifice (24) Jing high-temperature gases water conservancy diversion central canal (20) is directed to the combustor of furnace bottom and is burnt.Set in each combustor Fuel burner nozzle is put, combustion heating is used for when starting for black furnace and is heated up or the additional heat in activation process.Under in activation furnace Section high-temperature region, between upper and lower two sections activation tube annular cover plate is not provided with, water vapour carry out with raw material charcoal priming reaction generation CO, The fuel gas such as H2 a, part is passed directly to corresponding combustor and is burnt with heat-activated pipe, a part of Jing high-temperature gases Water conservancy diversion central canal (20) is directed to the combustor of furnace bottom and is burnt.Combustion gas pass through from lower to upper each combustor, are in Discharge from the flue gas outlet at top after the activation tube of the whole activation furnace of path heating of serpentine, and heating is arranged in flue Steam pipe coil being preheated with steam to activation therein, be then passed in waste heat boiler plus hot water steam confession activation With the activation tail gas after waste heat boiler is introduced to chimney and arranges to air.Activated carbon Jing after high-temperature activation is in discharge nozzle (3) In cooled down, by reducing motor drive discharging turn rake and discharge spiral constitute drawing mechanism (2) carry out continuous discharge, Can pass through to adjust the discharging speed of motor, and then adjust soak time of the raw material in activation tube with regulation activity charcoal product Decolorizing ability.

Vertical activation furnace described in this practicality has three innovations：One is arranged inside activation furnace using activation tail gas Make the self-produced water vapour of waste heat boiler of thermal source；Two is to arrange the pre- thermal activation of steam pipe coil in the flue of activation tail gas to be steamed with water Vapour, in each activation tube hub steam pipe and high-temperature gas mozzle are arranged, and allow high-temperature gas to be enclosed in outside steam pipe, to work Change water vapour is further heated, to improve the priming reaction speed of water vapour and raw material；Three are all set in every section activation tube Annular steam distributor pipe is put, water vapour is relatively evenly assigned in raw material to be activated, to improve the work of steam and raw material Change reaction effect.
