Abstract

The utility model relates to an improved refrigeration and discharge Serp activating furnace, comprising a activating furnace body (1) and a checker chamber; the activating furnace body is provided with a feeder port (1-1), a carbonization section (1-2), an activation section (1-3), a refrigeration band (1-4), a discharge device (5) and a carrier bar of the discharge device respectively from top to bottom; part of the channel (3) or the whole channel which is through the front and back in the refrigeration band is communicated to the outside. The utility model achieves high yield, high quality and low consumption of the absorbent charcoal.

Description

Improved cooling discharging Slapple activating furnace

Technical field:

The utility model relates to activated carbon production apparatus, particularly a kind of improved cold discharging Slapple activating furnace.

Background technology:

At present, the activation furnace that the domestic production activated carbon product is built mostly is a Stepple furnace, the cooling zone of Stepple furnace always is that to be enclosed in stove intravital, the iron and steel crossbeam that comprises steel dumping device and carrying dumping device, in the actual production process, temperature descended seldom when material was waited to arrive dumping device by airtight cooling, generally also about 800 ℃, the material of discharge port still is red, the consequence that causes is: the frequent scaling loss distortion of drawing mechanism and iron and steel crossbeam, gently then the part drawing mechanism can't discharging, and is heavy then cause the stopping production overhaul; Because temperature was too high when material was discharged, product burns mistake rate height, and oxidation is serious, and ash content increases, and quality product descends, and single pass yield is unable to lift.

Chinese patent " a kind of Stepple furnace drawing mechanism " (CN2651687Y) discloses a kind of Stepple furnace drawing mechanism, it mainly improves the discharger that is mounted in below the body of heater perpendicular to the air flue direction, this discharger is to be welded by two-layer horizontal fixed plate and two-layer blocking material plate in two blocks of side plates, centre at two-layer retaining plate is inserted with portable plate respectively, and is fixedly connected on the body of heater lower end with base plate by standing bolt.This utility model drawing mechanism is changed into uptake ventilator by parallel air flue, controls the blanking simultaneously of the identical or close product channel of activation phenomenon by a discharger.

This utility model is to have increased a cover drawing mechanism below existing furnace bottom newly, can not be from the cooling problem significantly before the basic solution material arrival furnace bottom.

Existing Stepple furnace cooling zone adopts enclosed construction mainly to be based on the mistaken ideas that academic aspect exists, promptly, worry the combustion chamber refractory brick of carrying high-temperature material in case directly contact with freezing air and quick oxidation can take place and burst apart, but facts have proved, in case cooling zone refractory brick is exposed in the air, as long as realize convection of air, the hull-skin temperature of refractory brick is reduced to below 400 ℃ naturally, by the preheating of heating, oxidation can not take place and burst apart freezing air in refractory brick near the process on refractory brick surface.

Summary of the invention:

The purpose of this utility model is to overcome the prior art defective a kind of cheap, improved cooling discharging Slapple activating furnace that method is easy is provided.

The purpose of this utility model realizes according to following proposal:

A kind of improved cooling discharging Slapple activating furnace, comprise activation body of heater and regenerator, activation has opening for feed, carbonization section, cooling zone, dumping device and carrier bar thereof respectively in the body of heater from top to bottom, the path partially before and after connecting in the cooling zone or all communicate with the external world;

In the described cooling zone hydrologic cycle cooling system is installed;

The described cooling zone air passageways of opening directly links to each other with ventilation plant;

Described ventilation plant comprises gas skirt and chimney that communicates with it or the induced draft fan that is arranged at cooling zone one side.

Invention effect of the present utility model is embodied in the following aspects:

1, high yield, high-quality, the low consumption of gac have been realized;

2, guarantee the key facility-iron and steel crossbeam safe handling of dumping device and bogey;

3, significantly improve the work-ing life of body of heater;

4, solved the product problem that afterfire oxidation, ash content increase of coming out of the stove;

5, solve the problem of operator in the high-temperature zone work under bad environment.

Description of drawings:

Fig. 1 is the utility model front schematic view;

Fig. 2 is the positive partial schematic sectional view of the utility model;

Fig. 3 is the A-A cross-sectional schematic of Fig. 2;

Fig. 4 is the situation synoptic diagram of Fig. 3 under the prior art situation.

Embodiment:

As shown in Figure 1 and Figure 2, the utility model main body is similar to conventional Stepple furnace, comprise activation body of heater (1) and regenerator (not drawing in the drawings), activation furnace is external service platform (2), be respectively to be drawing mechanism (4) and carrier bar thereof under opening for feed (1-1), carbonization section (1-2), activation section (1-3), cooling zone (1-4) cooling zone from top to bottom in the body of heater, discharge port (5) is arranged at the bottom; Improvement part of the present utility model is to connect passage (3) part of front and back in the cooling zone or all to communicate with the external world as shown in Figure 3, Figure 4, and number in the figure 7 is material passages in activation zone.

If envrionment temperature is too high, can set up a gas skirt in cooling zone one side, gas skirt receives on the chimney or induced draft fan, gas blower on forced ventilation;

Also can in passage (3), add the water jacket recycle system, reduce material temperature in the cooling zone by circulating water pipeline.

Claims
