Description
Technical field:
The utility model relates to a kind of construction material production equipment, be specifically related to the antiseized block apparatus of a kind of novel dry-process rotary kiln five-stage cyclone preheater, the sticking stifled problem of pre-heating system when being used to solve novel dry-process rotary kiln burning 40% above carbide slag and high chlor-alkali content material is to guarantee the production of dry-process rotary kiln system stability.
Background technology:
The large waste residue carbide slag of chemical industry is the high-quality calcareous raw material of system cement, and cement equipment manufacturer and technical staff author have all carried out number of research projects both at home and abroad.On the preheater rotary kiln, carried out a large amount of tests and application abroad, can solve the stable operation problem of carbide slag volume preferably in 15% following system; Domestic with the cement industry mandatory upgrade, large-scale institutes such as Tian Jinyuan, He Feiyuan, Cheng Douyuan, Inner Mongol institute, Nanjing institute and Wuhan cement research institute have all carried out a large amount of tests and practice with regard to the sticking stifled problem of the preheater of novel dry-process rotary kiln processing carbide slag, but because the Main Ingredients and Appearance of carbide slag is Ca (OH)
2(decomposing a large amount of high-temperature water vapor of generation at about about 584 ℃) is in normal five-stage cyclone preheater rotary kiln system, no matter be Ca (OH)
2Be carbonized still and decompose, all produce a large amount of water vapours (Ca (OH)
2+ CO
2→ CaCO
3+ H
2O ↑, Ca (OH)
2→ CaO+H
2O ↑), the high humidity stream of high concentration water's steam is by very thin raw material powder in the preheater, cause the preheater tapering sticking stifled to air valve and even pipeline, when serious even cause the cyclone preheater barrel successively to stick material and the whirlwind tube is blocked gradually, the preheater connecting pipe blocks, therefore, though in general five-stage cyclone preheater rotary kiln system through vast production, technical staff author's arduous effort, but the carbide slag consumption of guaranteeing to produce stable operation reluctantly is only below 30%, has to stop transport as the Shandong Zibo line of Hefei institute design and removes, newly-built Hunan dimension chemical industry cement dry method line is tried out over the past half year, and the volume of carbide slag also only can move below 25% reluctantly.Handle the problem of carbide slag for solving dry-process rotary kiln, have to take scheme with high investment and the waste energy consumption in the part institutes design process, as the Pyatyi preheater being kept to three grades of preheaters, earlier carbide slag carbonization drying is reentered three grades of preheaters to guarantee the stable operation reluctantly of rotary kiln pre-heating system so that EGT reaches more than 600 ℃.
On the other hand, the processing of name class waste material effectively economical by way of depending on cement kiln, but novel dry-process rotary kiln has strict restriction to harmful elements such as chlor-alkali sulphur, especially the industry design standard is limited in the raw material chlorinity below 0.015%～0.02%, alkali content is limited in below 1.0%, otherwise higher the formation to air valve and pipeline in three grades of cyclone preheater taperings easily of chlor-alkali content stickingly stifledly causes system normally not move, and this has just limited the use that the higher waste residue (as the water treatment filter mud) of chlor-alkali content and higher chlor-alkali contain content of starting materials widely.
Summary of the invention:
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and provide a kind of novel dry-process rotary kiln preheater antiseized block apparatus, solve that novel dry-process rotary kiln burns 40% above carbide slag and even the sticking stifled problem of preheater during all with carbide mud residue ingredient and high chlor-alkali material, guarantee to drop into and economic mode system's energy stable operation when handling waste residue with low.
The technical solution adopted in the utility model is: the antiseized block apparatus of this novel dry-process rotary kiln preheater comprises the antiseized block apparatus in preheater tapering, anti-buildup device and/or the antiseized buildup device of connecting pipe of sticking of preheater barrel; The preheater tapering is equipped with the air bubble that pressure-air flings discharge pipe, air valve turnover panel and tapering; The anti-buildup device that sticks of preheater barrel is equipped with the air bubble that pressure-air cleaning barrel high humidity sticks material; The antiseized buildup device of connecting pipe is installed the air bubble of the sticking buildup of pressure-air cleaning tube wall in easy buildup section.
In the technique scheme, air bubble be general can timing automatic work done, the air bubble system of pressure 0.5MPa～2.0MPa.
In the technique scheme, the anti-air bubble that sticks the installation of buildup device of preheater barrel adopts in 0～15 ° in barrel upper edge whirlwind direction and tilts to be provided with at interval one group to three groups air bubble, 2 to 5 of every group of air bubbles are provided with 2 or a plurality of air bubble vertically downward along barrel.
The antiseized block apparatus of novel dry-process rotary kiln preheater of the present utility model, be mainly used in the antiseized block apparatus that novel dry-process rotary kiln burns 40% above carbide slag and even all uses carbide mud residue ingredient, general emphasis is in high concentration water's steam influence of reply secondary preheater and one-level preheater, 2～3 air bubbles should be set in secondary preheater tapering, one of them flings the air bubble of air valve turnover panel and discharge pipe towards sweeping work done after fixing on 50～120 seconds, one-level preheater tapering is provided with 1～2 air bubble, and one of them flings the air bubble of air valve turnover panel and discharge pipe towards sweeping work done after fixing on 3～30 minutes.One-level, secondary cyclone preheater barrel prevent that sticking buildup should be provided with 1～3 group of air bubble.Three grades, level Four, air bubble that flings air valve turnover panel and discharge pipe of Pyatyi preheater tapering operated by rotary motion, with timing automaticly dash about the discharge pipe sweep the low melting point mineral brought into because of carbide slag and to cause, the turnover panel, the sticking buildup in tapering, dash sweep work done after should fix on 60 seconds～30 minutes.The on-the-spot pipe arrangement of pan is dashed in the timing of pipeline and sticking stifled buildup situation is fixed.
When the utility model is applied to burn high chlor-alkali waste material, general emphasis is in three grades of preheater taperings and Pyatyi to three grade preheater connecting pipe, should 1～3 air bubble be set in three grades of preheater taperings, the air bubble that wherein flings air valve turnover panel and discharge pipe dash sweep work done after should fix on 60 seconds～30 minutes, the similar processing of kiln system situations is looked different in other what preheater tapering, handles pipeline and sweeps because of the air bubble of the sticking buildup of chlor-alkali steam influence regularly dashes to be provided with and look on-the-spot pipe arrangement and sticking buildup situation is fixed.
The antiseized block apparatus of pre-heating system when the utility model is mainly used in dry-process rotary kiln burning 40% above carbide slag and high chlor-alkali material, the sticking buildup that the timing automatic cleaning of the air bubble that flings air valve turnover panel and discharge pipe tapering, turnover panel reach pipeline up and down is installed in the preheater tapering, perplex the sticking stifled of high volume carbide slag of preheater klining and high chlor-alkali material for a long time and problem that can not stable operation with effective solution, broken through novel dry-process rotary kiln in profit universally acknowledged " harmful element " restriction bottleneck on the useless and raw material.Have following remarkable advantage:
1, solved novel dry-process rotary kiln burning 40% above carbide slag and reached, solved high chlor-alkali material and seriously hindered dry method kiln pre-heating system stable operation problem all with the production stable operation problem of carbide mud residue ingredient.
2, adopt general air bubble investment little, be provided with install simple.
