Description
Technical Field
The utility model relates to a heat preservation structure of rotary kiln cooling system manger plate cover.
Background
The rotary kiln incinerator is a commonly used high-temperature furnace, the equipment condition and the regular maintenance cost of the rotary kiln incinerator are critical to a production unit, and the most intuitive influencing factor is the temperature control of the outer surface of the rotary kiln. The high temperature of the outer surface of the rotary kiln not only causes the expansion of the kiln body and unstable rotation, which affects the service life of the equipment, but also loses energy and affects the operation environment when dissipating heat to the surrounding environment.
To this end, the applicant disclosed in utility model patent ZL201720982296.0 a system for cooling the surface of a rotary kiln. The cooling circulation system comprises a kiln body 1, a cooling unit, a hot water recovery unit and a heat exchange unit. The cooling unit comprises a water inlet main pipe 20, a plurality of spray pipes 22, a plurality of nozzles 23, a water retaining device and a water receiving device. The water retaining device comprises a water retaining cover 24 and cover plates connected to the front end and the rear end of the water retaining cover 24; the water shield 24 is arranged at the periphery of the plurality of spray pipes 22, and the cooling circulation system uses circulating water to cool the outer wall of the rotary kiln body 1 and recover heat (see fig. 1 and 2). Because the steel structure water retaining cover 24 of the cooling circulation system directly contacts with the ambient air, the heat loss is large, and heat preservation measures need to be implemented on the water retaining cover 24. For the heat preservation of the steel structure water retaining cover, the common method is to cover the surface of the water retaining cover with rock wool materials and protect the water retaining cover with galvanized plates after fastening. The heat preservation effect of the heat preservation structure is good in the initial stage, but when the heat preservation structure is used on the water retaining cover 24 of the cooling circulation system on the surface of the rotary kiln, part of water vapor is diffused to the outer surface of the water retaining cover 24 and condensed into water drops because the water is sprayed into the water retaining cover 24 to cool the rotary kiln 1. The waterproof performance of the rock wool material is poor, the heat preservation effect of the rock wool is influenced by soaking the rock wool material in water for a long time, and the installation difficulty is high. Moreover, the rotary kiln 1 belongs to a high-temperature area, and the temperature can reach 400 ℃, so the organic heat-insulating material is not suitable for the water retaining cover 24 of the rotary kiln cooling system.
