Abstract

The utility model provides a combined roaster which comprises a slewing barrel and a heat preserving hearth, wherein a material inlet is formed at one end of the slewing barrel; a material outlet is formed at the other end of the material inlet; the slewing barrel is sleeved with the heat preserving hearth; the roaster further comprises a direct burner and indirect burners; the direct burner is arranged at a discharge end of the roaster; and the indirect burners are arranged on the heat preserving hearth.The roaster employs a burning system combining direct burning and indirect burning; the indirect burners burn outside the slewing barrel of the roaster and supply heat indirectly; high-temperature smoke generated by burning is not directly contacted with a material and provides heat for roasting the material in the rotary furnace mainly via heat radiation; the direct burner is arranged at the discharge end of the roaster; and high-temperature smoke generated by the burning enters the slewing barrel and is directly contacted with the material for heat supply.The roaster employs the combined burning system, and has high roasting temperature control precision, the heat efficiency of a roasting system can be effectively improved, the yield and quality are increased and improved, indirect and direct heat load proportion can be adjusted at the same time, and the roaster is applicable to roasting various materials.

Description

A kind of combined type roaster
Technical field
The utility model relates to a kind of roaster combustion apparatus, is specifically related to the roaster of a kind of direct burning and the combined formula of indirect burning.
Background technology
Roasting is the process of carrying out high-temperature heat treatment after moulding through pre-dried wet stock in roaster by certain programming rate.Roaster (being also calcining furnace or rotary kiln) is extensively used the post processing of the materials such as ore, catalyst, molecular sieve and active carbon.Roaster is one of key equipment in catalytic cracking catalyst production process, it mainly removes volatile components and chemical bonding water in material by pyrolysis, make catalyst obtain certain crystal formation, grain size, pore structure and specific surface, form stable structure and improve mechanical strength.
Roaster generally, using coal, combustion gas, oil and electric etc. as thermal source, is divided into direct heating and the large class of indirect two by heating means.Petrochemical industry generally adopts indirect heating type, and so that wherein combustion type roaster and electrothermal roaster are more common.
Domestic roaster and foreign technology have a certain distance, be mainly reflected in burner structure backwardness, combustion system unreasonable allocation, sintering temperature control is improper etc., causes the shortcomings such as the roasting system thermal efficiency is low, energy consumption is high, exhaust emissions is not up to standard, product percent of pass is low.
Utility model content
In order to solve the problems such as domestic combustion type catalyst roaster burner structure backwardness, combustion system unreasonable allocation, sintering temperature control be improper, improve the roasting system thermal efficiency, reduce energy consumption, improve product percent of pass, the utility model provides the roaster of a kind of direct burning and the combined formula of indirect burning.
Concrete technical scheme of the present utility model is as follows:
A kind of combined type roaster, this roaster comprises rotating cylinder and insulation burner hearth, rotating cylinder one end is provided with material inlet, the other end is material outlet, insulation burner hearth is sleeved on outside rotating cylinder, also comprise direct burner and indirect burning device, directly burner arrangement is at the discharge end of roaster, and indirect burning device is arranged on insulation burner hearth.
Further design of the present utility model is: described indirect burning device is multiple, is evenly arranged in the side of insulation burner hearth.
12 of described indirect burning devices, directly 1 of burner.
The air-fuel ratio of indirect burning device is 30 ~ 40, turndown ratio, burner regulation ratio 5 ~ 10.Directly burner arrangement is at the discharge end of roaster, and the high-temperature flue gas that burning produces enters rotating cylinder inside, directly contacts heat supply with material.Directly burner air-fuel ratio 30 ~ 60, regulates than 5 ~ 10.
Directly burner arrangement is at the discharge end of roaster, and high-temperature flue gas and Flow of Goods and Materials direction that directly burner produces are adverse current, discharges with the feed end from roaster after material-heat-exchanging.
The thermic load ratio of indirect burning and directly burning can require to regulate according to different process, applicable to the roasting of various materials.
the utility model has following characteristics and advantage compared with existing technology:
The combined type roaster of the utility model design, adopts the combined combustion system of directly burning and indirect burning, can improve roasting accuracy of temperature control, improves the roasting system thermal efficiency, improves roasting quality, reduces production costs.Simultaneously adjustable indirect and direct thermic load ratio, can be applicable to the roasting of various materials.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-material inlet; 2-stove cylinder gas vent; 3-rotating cylinder; 4-is incubated burner hearth; 5-burner hearth exhanst gas outlet; The direct burner of 6-; 7-material outlet; 8-indirect burning device.
Detailed description of the invention
