With the accumulation of potassium and sodium in the soot, the recovered kiln ash is small in fineness, light in weight and viscous, and it is easy to block the pores of the filter bag. It is difficult to fall off when cleaning, and the ash effect is poor, which causes the kiln surface to pour smoke. It affects both fire operation and safety. Therefore, we will directly mix the recovered kiln ash with the clinker. As long as the kiln ash is controlled to less than 5%, the cement can be qualified. Before the transformation, the ordinary cover plate controlled by the hoist is used. Due to the impact of hot air flow and deformation during operation, it is not easy to reset after lifting, and the air leakage is very serious, which intensifies the formation of condensation. In this transformation, the original cover is removed, the 200mm water-cooled butterfly valve is selected, and compressed air is used as the power. According to the temperature change, the microcomputer automatically controls the opening and closing, and at the same time, to further protect the dust collector, the microcomputer automatically controls the dust removal according to the temperature change. The safety factor of Jiangsu dust-free is greatly improved, which avoids burning the filter bag at high temperature and solves the condensation problem at low temperature. During normal operation (automatic state), when the temperature of the precipitator population rises to 20 °C, the cold air valve opens with cold air; if the inlet temperature continues to rise to 280 °C, the 20O0mm butterfly valve will automatically open and directly discharge to the outside, when the inlet temperature is low. At 200 °C, the cold air valve is closed and the cold air is over. (The above operation procedure must be strictly observed in the manual state. It should be noted that the kiln dust recovered by the dust collector must not be re-into the raw material system and re-formed into the ball kiln, otherwise it will cause Determination of the operating parameters of potassium and sodium components and handling precautions. The LFEF glass fiber bag dust collector has two kinds of cleaning methods: timing and fixed resistance. Considering the instability of the vertical kiln flue gas, we use the timing cleaning method for the convenience of operation. The cleaning cycle is an important parameter in the control of the dust collector. The cycle setting is too long, the bag is thick and ash thick, the system resistance is large, and the fan load is increased, and the condensation is extremely likely to occur. The cycle setting is too short, frequent cleaning, although it can effectively solve the condensation problem, but it is not conducive to the formation of the secondary filter layer on the surface of the filter bag, affecting the dust removal effect, and excessive cleaning will seriously damage the filter bag, greatly reducing the service life of the filter bag. increase cost. Through practice, we set: winter and spring, the climate is cold, the air humidity is large, the cleaning cycle is set to 3Omm, and each room is cleaned 405; in summer and autumn, the temperature is higher, the air humidity is small, and the cleaning cycle is extended to 45mm. , each room is cleaned 405. Operation points Before starting the dust collector, carefully check whether the moving parts are flexible and reliable, and whether the compressed air pressure is greater than 0.4 MPa, and confirm that there is no abnormal situation before starting. When igniting the kiln, it is forbidden to put the dust collector into operation at this time. When the drying furnace is finished feeding, start the main induced draft fan, open the O.120mm butterfly valve, close the 200mm butterfly valve, and warm the drying bag first. When the outlet temperature is higher than 90 °C, the dust collector can be operated normally, and the control mode is changed to " automatic". When the kiln operation is restarted after stopping the material, the drying bag must be heated first. After the outlet temperature is greater than 90 °C, the normal fire operation can be invited. During normal operation, the temperature of the precipitator population is strictly controlled between 60 °C and 280 °C (the practice has proved that it does not affect the seed satin burning, does not increase energy consumption), and the fan outlet temperature is not lower than 65 °C. When the outlet temperature of the precipitator is lower than 65 °C and the time exceeds 1 h, the material should be stopped immediately and the normal feed should be resumed when the temperature of the precipitator population rises above 120 °C. Before stopping the kiln, first warm the baking bag to the outlet temperature is greater than 90 °C, and manually repeat the cleaning to the ash discharge, first stop the Roots blower, then stop the main induced draft fan, open the Zoomom butterfly valve, close the 01200mm butterfly valve. The dust collector shall be continuously deactivated for more than 48 hours. When the weather is fine, the manhole door of the bag room shall be opened and the bag shall be aired for 4h-6h. When the fireworker is in the operation of the calcination, it should always adhere to the full-wind and dark fire continuous satin burning. The position of the bottom fire should be controlled at the upper part of the lower end of the flare. The bottom fire should not be drawn deep to the straight part below the flare. It is strictly forbidden to increase and decrease when adding or unloading.
