Description
Technical Field
The utility model relates to a zinc oxide powder preparation technical field, concretely relates to high-efficient settling chamber for preparation of zinc oxide powder.
Background
The most current advanced zinc-oxygen powder production process of a zinc oxide rotary kiln production line has the technical principle that zinc powder, coke and the like are mixed according to a certain proportion and then conveyed to the kiln tail of a rotary kiln through a conveying belt, then under the continuous rotation of the rotary kiln, raw materials sequentially pass through a drying section, a preheating section, a middle-temperature section and a high-temperature section, finally, various metal steam such as zinc steam and high-temperature steam-solid mixtures such as coal dust and the like are generated in the high-temperature section, after the high-temperature steam-solid mixtures are generated, under the action of strong induced air and blast air in the kiln, the high-temperature steam-solid mixtures reversely enter the middle-temperature section, the preheating section and the drying section, and finally enter a settling chamber, and the settling chamber has the functions of: separating, radiating and continuously oxidizing various oxides, dust and the like contained in the high-temperature gas-solid mixture; the impurities that are not oxidized are removed by falling from the lower end of the settling chamber by settling (the impurities fall out of the settling chamber and are then returned to the kiln for use), while the light gaseous oxides enter the baghouse. The problems with the settling chambers currently used are: generally, the temperature of a settling chamber is reduced mainly by the heat transfer between the body of the settling chamber and the surrounding air, and a water cooling system is designed at the upper part of the settling chamber; generally, the temperature of the gaseous oxide before entering the bag-type chamber can be ensured not to exceed 160 ℃ through the above mode, however, if the outside air temperature is high in summer, high temperature in a plant is difficult to diffuse quickly, the situation that the heat dissipation effect of the body of the settling chamber is not good can occur, at this time, although the circulation of the water cooling system can be slightly accelerated to improve the temperature reduction, the regulation effect of the water cooling system is limited, and how the water cooling circulation is too fast, the temperature at the front section of the settling chamber is too low, so that the metal gaseous oxide (zinc oxide steam) is cooled excessively, and the metal gaseous oxide falls off as impurities are settled, so that the yield of the end product of the production line is reduced, but if the outside environment is at high temperature, the temperature entering the bag-type chamber is too high, so that the bag-type chamber burns out, which is a contradictory process. However, according to the observation and research, it is found that a part of the high temperature in the settling chamber is caused by too high temperature of the mixture settled in the lower part of the settling chamber, because the settled mixture contains a large amount of coal dust, and the mixture pumped into the settling chamber through the rotary kiln contains a part of the coal dust in a high temperature state besides the metal gaseous oxides, and the high temperature of the mixture settled in the lower part of the settling chamber has no effect and can affect heat dissipation, so that the temperature in the settling chamber is high, therefore, the cooling device additionally arranged on the lower part of the settling chamber provides an effective idea for solving the technical problems, but the cooling device arranged on the lower part of the settling chamber can encounter the following problems: firstly, the lower part of the existing settling chamber is funnel-shaped (the lower part structure of the existing settling chamber is basically similar to the attached drawing disclosed by the following patent documents and is named as a secondary zinc oxide settling chamber with high settling efficiency, the application (patent) No. 202010828678.4, the publication (announcement) No. CN112023530B, or a product of the settling chamber in zinc oxide rotary kiln production line equipment produced by the brand such as Henan Huaguan and the like sold at present), the space of the lower part is limited, and the existing cooling device with large volume cannot be used, so that the aggregation effect and falling of particle mixtures can be influenced, other new problems such as blockage and the like are caused, and the normal production is disturbed; however, if only a few water pipes are inserted, the contact area between the water pipes and the middle lower part of the settling chamber is insufficient, the adjusting effect is very limited, and the water pipes do not play an effective role.
