Therefore, a large amount of high-grade energy is wasted in the preheating zone
In addition, the combustion air provided by the combustion lance in the sintering zone needs to be preheated, so as to achieve a good combustion effect and reduce the emission of pollutants. However, special equipment is required for air preheating, which consumes special energy.
Therefore, the existing ceramic kiln system has the disadvantages of high energy consumption and low efficiency due to its imperfect structure.

Embodiment Construction
[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0014] Ceramic kiln energy-saving retrofit system, such as figure 1 As shown, the hearth of the furnace body is successively divided into a preheating zone 3, a sintering zone 13 and a cooling zone 9, and the sintering zone 13 is provided with several burners 6 for sintering. The furnace of the preheating zone 3 is connected to a power generation device 12, and the power generation device 12 uses the high-temperature air in the preheating zone 3 to generate electricity, and the exhaust gas from the power generating device 12 is introduced into the preheating zone 3 of the ceramic kiln. In the furnace, this can effectively use the high-grade energy of the preheating zone, but it will not affect the production of the ceramic kiln. A plurality of retaining walls 10 are arranged alternately in the preheating zone 3 to prolong the air traveling p...

The invention discloses an energy-saving transformation system for a ceramic kiln. The hearth of the kiln body is sequentially divided into a preheating zone, a sintering zone and a cooling zone, wherein a plurality of nozzles are arranged on the sintering zone; the preheating zone is connected with a power generation device, and high-temperature air in the preheating zone is used for generating power; and the smoke exhausted by the power generation device is introduced into the hearth in the preheating zone. The energy-saving transformation system has the advantages that (1) high-temperature taste energy in the preheating zone is fully utilized, power is generated for other equipment under the condition that the production is not influenced, and the resources can be reasonably used in an optimized mode; (2) the tail gas generated by the power generation device and the tail gas of the cooling zone are fully utilized for heating air and supporting combustion, so that the aim of effectively recycling the heat source is fulfilled; (3) the improvement can be performed on the basis of the conventional equipment, the main body structure of the conventional equipment is not required to be changed, and the system is easy and convenient to implement; and (4) the energy can be greatly saved, and heat loss and environmental pollution are slightly emitted.
Description
technical field [0001] The invention relates to an energy-saving system for a kiln, in particular to an energy-saving transformation system for an energy-saving ceramic kiln. Background technique [0002] The existing ceramic kiln system includes preheating zone, sintering zone and cooling zone. The temperature in the preheating zone can reach over 1000 degrees, but in the ceramic production process, the preheating temperature required for waste heat only needs to be about 300 degrees. A large amount of high-grade energy is thus wasted in the preheating zone. In addition, the combustion air provided by the combustion lance in the sintering zone needs to be preheated, so as to achieve a good combustion effect and reduce the emission of pollutants. However, special equipment and energy consumption are required for air preheating. Therefore, the existing ceramic kiln system has deficiencies such as high energy consumption and low efficiency due to imperfect structure. Conte...
