Abstract

The utility model relates to a miniature activating furnace for activated carbons, which is composed of a combustion furnace (1), an activating reaction furnace (2), and hot water steam kettles A and B. The combustion furnace is in parallel to the activating reaction furnace, which are connected through a smoke channel, and the heat in a blast chamber enters the activating reaction through the smoke channel to activate the charry materials. The hot water steam kettles are positioned on the burner of the smoke channel and the blast chamber, the moisture tubes D and C of the hot water steam kettles are inserted into the smoke channel, and the moisture tubes E are inserted into the activating reaction furnace. The utility model has the advantages of simple structure and low cost, and can be used to produce the national standard activated carbons.

Description

Miniature activating oven for activated carbon

The utility model belongs to produces the gac activating reaction furnace.

At present, produce the routine techniques of gac both at home and abroad, mostly need the producer gas generator supporting with activating reaction furnace, equipment such as high pressure steam boiler and air compressor, therefore, in general, facility investment is higher, industrial scale is bigger, is the technology that general medium-sized and small enterprises are not dared to inquire.

The purpose of this utility model is to provide a kind of small-sized activation furnace of gac that does not need producer gas generator, air compressor and high pressure steam boiler equipment for medium-sized and small enterprises and individual enterprise, is characterized in less investment (only 10,000 yuan get final product), the little (10m of floor space ²Can activate production, 80m in the area ²The place can go out finished product), quality of activated carbon height, the performance produced are good, through country-level unit of measure test analysis, active fruit shell carbon has reached national standard, its methylene blue decolorizing ability is 14.7ml, this granular active carbon can be used as produces the rare synthetic uses such as coal, vinylon catalyst charcoal, gold carbon and infiltration charcoal of touching of acetic acid second, and powdered active carbon can be used as uses such as decolouring, pharmacy and scientific research.

Introduce structure of the present utility model in detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is the utility model diagrammatic cross-section.

Accompanying drawing 2 is a floor map.

Accompanying drawing 3 is the activating reaction furnace synoptic diagram.

This activation furnace comprises combustion furnace (1), activating reaction furnace (2) and hot water and steam pot A, B, and this combustion furnace and activating reaction furnace are arranged side by side, is connected by smoke flue (3); Combustion furnace inner combustion chamber (4) is closed, the ashcan (16) that be equipped with below several fire bars (15), the fire bars inside locates to be provided with an air inlet (5), the combustion chamber downside is provided with secondary air inlet (6), and they can be pressed into smoke flue (3) to the oxygen supply of stove internal combustion and with pyrotechnics in the stove. Top of combustion chamber is provided with a burner (13), and this sits hot water and steam pot B above burner, also can add fuel in stove; Activating reaction furnace (2) inside is date core shaped, and the bottom is communicated with smoke flue, and chimney (8) is established at the top, and the upper, middle and lower, side are respectively equipped with charge door (9) everywhere, observe gathering hole (10) and discharging opening (11); In the smoke flue (3), be provided with a stifled half heated-separated wall (12) along the pyrotechnics direction, can enter in the activating reaction furnace (2) along heated-separated wall both sides and top from the pyrotechnics heat of combustion chamber; Another hot water and steam pot A, two vapour pipe D that are connected with the A pot are equipped with in the smoke flue top and C all inserts in the smoke flue (3), and the D pipe is fork-shaped and is divided into two arm D in smoke flue₁、D ₂, they are laid on respectively at the bottom of the heated-separated wall both sides, and the C pipe then is layed in the heated-separated wall top. Vapour pipe D in the above-mentioned smoke flue₁、D ₂On C, be evenly equipped with several spray orifices (14); With the vapour pipe E that hot water and steam pot B is connected, its terminal insertion in the activating reaction furnace; Also be inserted with thermoelectric corner (7) in this activating reaction furnace, be used at any time measuring the temperature in the reacting furnace.

Method of operating of the present utility model and operation principle are: at first give thermal activation reacting furnace and heat hot water steam copper A, B, namely open a blast orifice (5) and carry out air blast oxygen supply burning to the combustion chamber, temperature rises to 800 ℃ in activating reaction furnace, water is when boiled in the A, B pot, in activating reaction furnace, add an amount of charing material, and open the air blast of post-blast mouth, at this moment, the charing material namely comes to life; When temperature in the activating reaction furnace rose to more than 850 ℃, material just began activation, at this moment, should open the vapour pipe E on the B pot, and to activation material spray water vapour, and the control material balances the boiling. When temperature in the reacting furnace surpasses 1000 ℃, can open A pot D vapour pipe, by arm D₁And D₂In smoke flue, spray steam, to reduce furnace temperature. When material in the stove seethes with excitement when bad, open the C pipe, can help the material boiling to reacting furnace bottom water spray vapour.

In the activation act process,, need to carry out an on-the-spot sample analysis (i.e. look is seen in sampling), to judge the priming reaction situation every 10 minutes for guaranteeing the quality of its gac.
