Description

The wood activated charcoal pierce smith converter

Technical field

The utility model relates to the wood activated charcoal production unit, specifically, relates to a kind of wood activated charcoal pierce smith converter.

Background technology

Along with the progress of society and people to improving constantly that quality of life requires, as the wood activated charcoal of decontamination toxin expelling impurities removal, demand is increasing, use range also more and more widely.All need use as industries such as medicine, sugar industry food, makeup, urban water supply, tobacco, drinks, chemical industry, vehicle exhaust processing, in addition, in the military affairs to the demand of gac also in continuous increase, and still do not have substitute.Therefore, the economic outlook of wood activated charcoal is very good.

The main raw material(s) of wood activated charcoal is the discarded wood chip of production of forestry, and traditional production technique is to adopt the phosphoric acid method, by pierce smith converter wood chip is carried out charing and activation.As the main production equipments of wood activated charcoal, pierce smith converter is generally the empty barrel structure of inner lining refractory block.But, because the defective that traditional pierce smith converter self exists in process of production, tends to occur following problem:

1, wood activated charcoal unstable product quality is difficult to produce high-quality wood activated charcoal product.Specifically, the main index iodine sorption value of wood activated charcoal product is difficult to be stable at 〉=1000mg/g, and the methylene blue adsorption rate is difficult to be stable at 〉=16mL/0.1g;

2, in order to make the wood activated charcoal product up to standard, pierce smith converter outlet exhaust temperature must be controlled more than 180 ℃, has caused a large amount of heat-energy losses;

3, the phosphoric acid acid mist amount of carrying secretly is big in the pierce smith converter outlet tail gas, so that caused the phosphoric acid consumption of product to increase;

4, because the acid temperature is high, pierce smith converter feed auger equipment corrosion accelerates, and has caused the equipment failure rate height, has finally influenced the working efficiency of complete assembly;

5, in the wood activated charcoal production process, employed wood chip charing and activation efficiency in pierce smith converter is low, has directly influenced the production capacity of pierce smith converter, is 35 meters with length, and diameter is that 1.8 meters pierce smith converter is example, and its maximum production capacity can be above 7 tons/day.

In order to solve the above problems, existing some wood activated charcoal manufacturing enterprise has proposed following solution at present:

1, in the inner lining refractory block building process of pierce smith converter inside, sets up the lifting gear of some special shaped brick structures, to improve charing and the activation efficiency of wood chip.Yet, because the strength problem of special shaped brick structure, it is too big that lifting gear can not be done, generally, the lifting bench height of lifting gear can not surpass 150mm, has caused charing and the not significant lifting of activation efficiency of wood chip thus, simultaneously, because the lifting gear of special shaped brick structure comes off in operational process easily, is unfavorable for the steady running of pierce smith converter.

2, in the inner lining refractory block of pierce smith converter inside, install the lifting flight of fixing some stainless steels additional, this brings certain help to charing and the activation efficiency that improves wood chip, but also there are a lot of problems simultaneously: promote the increase of flight, changed the residence time of wood chip in pierce smith converter, also namely change the time of charing and the activation of wood chip, caused the wood activated charcoal unstable product quality easily; In addition, owing to unreasonable (the general method installation lifting flight of beating expansion bolt at inner lining refractory block that adopts) of fixed form, and the influence of the interior high temperature of pierce smith converter and corrosion, promote flight and often come off, be unfavorable for the steady running of pierce smith converter.

The utility model content

The purpose of this utility model is, provides a kind of wood activated charcoal pierce smith converter, to solve the problems of the technologies described above.

For addressing the above problem, the technical scheme that the utility model adopts is:

A kind of wood activated charcoal pierce smith converter, comprise the high low dip setting of tail the stove tube, be located at the inner lining refractory block on the stove tube inwall, the preceding wheel holding mechanism that is located at the stove tube bottom, middle wheel holding mechanism, back wheel holding mechanism and drive the driving mechanism that the stove tube rotates around the axle center; It is characterized in that: be provided with some groups in the furnace chamber of described stove tube afterbody feed end and advance flight, be provided with some groups in the furnace chamber of described stove tube front portion and promote flight; Offer the open holes that advances flight and lifting flight for fixed installation on the described stove barrel; The afterbody of described propelling flight fixedly has at least two to advance the flight pipe, and the afterbody of described lifting flight fixedly has at least two to promote the flight pipe; Described propelling flight pipe and lifting flight pipe corresponding pegging graft respectively are fixed in the described open holes; The top of the top of described propelling flight and lifting flight all is provided with the bending of arc.

Say that further the bending part at described lifting flight top and the distance between the afterbody are not less than 250mm.

Furtherly, in the gap between described propelling flight pipe and the corresponding open holes and promote in the gap between flight pipe and the corresponding open holes and all be filled with the high temperature clay.

Beneficial effect: owing to adopted technique scheme, the utility model is by the propelling of design pierce smith converter and the reasonable combination of lifting flight, and carried out rational transformation at aspects such as flight self structure intensity, material and fixed forms, under the prerequisite that does not change wood chip charing and soak time in converter, can improve charing and the activation efficiency of wood chip, reduce the consumption of heat-energy losses and phosphoric acid, reduce equipment failure rate, promote quality product and the production capacity of wood activated charcoal.
