The utility model provides a boiling and calcining furnace which is easy to observe and has good calcining effect. The boiling and calcining furnace comprises the calcining furnace; the calcining furnace consists of a combustion chamber and a flue which is at the side of the combustion chamber and is provided with a discharge hole; the combustion chamber is connected with a combustion machine; the bottom of the flue is provided with a back flow column; and the side of the back flow column is provided with a back flow port. The boiling and calcining furnace is structurally characterized in that the flue wall corresponding to the upper part of the back flow column is provided with an observation hole and a feeding hole respectively; and the tail of the combustion chamber is provided with a high temperature feeding pipe.
Description
Technical field:
The utility model relates to the improvement of the structure of calcining furnace.
Background technology:
Calcining is the chemical engineering process of the improvement that is applicable to inorganic salts, decomposition, purification, oxidation, reduction.The calciner of widespread usage has rotary kiln, pushed bat kiln, stationary kiln, ebullated bed etc. now.
1, rotary kiln:
Rotary kiln is a kind of half dynamic calciner that is commonly used in the inorganic salts drying, the major defect of its existence be the equipment operation need huge power, energy consumption than higher, the regular maintenance expense is big, seriously polluted, atmosphere material calcining is poor, the calcination surface area is little;
2, pushed bat kiln:
Pushed bat kiln is a kind of quantity-produced calciner, and its floor space is big, and calcination time is long.Need use crucible when calcining materials, its expense is bigger.Though it is continuous production, belong to static calcining, the calcining effect is relatively poor relatively, energy consumption is high, during discharging environmental pollution big;
3, stationary kiln:
Stationary kiln is a kind of discontinuous production equipment, and production capacity is low, calcination time is long, energy consumption is big, and the product quality after the calcining is difficult to guarantee, is typically equipped with follow-up equipment, poor working environment, the incompatible big needs of producing;
4, ebullated bed:
Though ebullated bed is a kind of fluidizing calcination equipment, can overcome the shortcoming of above-mentioned three kinds of calcining furnaces, but still there is the shortcoming that combustion efficiency is undesirable, observe inconvenient operation.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of easy observation, the effective fluidized-bed kiln of calcining are provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises calcining furnace, calcining furnace is made up of the flue with discharge gate of combustion chamber and side, combustion chamber, the combustion chamber links to each other with combustor, the bottom of flue is the refluence post, and the side of refluence post is for flowing backwards mouthful, and its structural feature is to be respectively arranged with peep hole, charging aperture on the walling of flue corresponding to the top of refluence post; The afterbody of combustion chamber is provided with the high temperature charge pipe.
The beneficial effects of the utility model:
Because the utility model is respectively arranged with peep hole, charging aperture on the walling of flue above the effluent post; The afterbody of combustion chamber is provided with the high temperature charge pipe; So help the abundant burning of material, reach desirable calcining effect; And help combustion case is observed, determine reinforced situation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the utility model structural representation with auxillary flue;
Fig. 4 is the B-B cutaway view of Fig. 3.
The specific embodiment:
The utility model comprises calcining furnace 10, calcining furnace 10 is made up of the flue with discharge gate 11 9 of combustion chamber 6 and 6 sides, combustion chamber, combustion chamber 6 links to each other with combustor 8, the bottom of flue 9 is a refluence post 2, the side of refluence post 2 is for flowing backwards mouthful 1, is respectively arranged with peep hole 3, charging aperture 4 on flue 9 walls corresponding to the top of refluence post 2; The afterbody of combustion chamber 6 is provided with high temperature charge pipe 5.
Discharge gate 11 also can link to each other with auxillary flue 12, and the bottom of auxillary flue 12 is provided with discharge gate 11.Auxillary flue 12 can make material obtain further burning fully.
Below in conjunction with a description of drawings course of action of the present utility model:
The material of needs calcinings after the high-temperature gas of the air inlet 7 of 6 sides, combustion chamber mixes, is rotary fluid shape fluidization campaign, and 6 calcining 8-15 around 2 rotations of refluence post, make material separated from the gas after second again in the combustion chamber, again through 11 discharges of flue 9 discharge gates.
Claims (2)
1. fluidized-bed kiln, comprise calcining furnace (10), calcining furnace (10) is made up of the flue with discharge gate (11) (9) of combustion chamber (6) and side, combustion chamber (6), the same combustor in combustion chamber (6) (8) links to each other, the bottom of flue (9) is refluence post (2), the side of refluence post (2) is flow backwards mouthful (1), it is characterized in that being respectively arranged with peep hole (3), charging aperture (4) on flue (9) wall corresponding to the top of refluence post (2); The afterbody of combustion chamber (6) is provided with high temperature charge pipe (5).
2. a kind of fluidized-bed kiln according to claim 1 is characterized in that the same auxillary flue of discharge gate (11) (12) links to each other, and the bottom of auxillary flue (12) is provided with discharge gate (11).
