Embodiment Construction

[0023] figure 1 Schematic diagram of the waste heat utilization hot air preheating system of the oxygen-enriched combustion daily-use ceramic roller kiln. The technical embodiment of the invention is: the daily-use ceramics placed on the backing plate pass through the transmission of the ceramic roller rod 1, and then pass through the preheating zone 2, the firing zone 3 and the cooling zone 4 in the roller kiln in sequence; the ceramic green body Firing is carried out in the firing zone according to its predetermined firing system, and the hot flue gas in the firing zone 3 flows from the firing zone 3 to the pre-tropical zone 2 under the action of the kiln head smoke exhaust fan 15, and the ceramic green body Form the reverse movement; after the firing of the ceramic green body, it enters the cooling zone 4 through the rapid cooling air curtain between the firing zone 3 and the cooling zone 4; the product is rapidly cooled in the cooling zone 4 according to the cooling proces...

Abstract

The invention discloses an oxygen-enriched combustion domestic ceramic roller kiln waste-heat utilization hot-air preheating system. The oxygen-enriched combustion domestic ceramic roller kiln waste-heat utilization hot-air preheating system comprises hot air acquisition pipelines, a first conveying pipeline, an induced draft fan, a second conveying pipeline, a branch conveying pipeline, and a hot air distributor which is arranged in a roller kiln preheating zone; multiple hot air acquisition pipelines are arranged at a plurality of positions in a cooling zone kiln body of the roller kiln; the hot air acquisition pipelines are communicated with the first conveying pipeline; an inlet/outlet of the induced draft fan is communicated with the first conveying pipeline and the second conveying pipeline respectively; an outlet end of the second conveying pipeline is communicated with the hot air distributor which is arranged in the roller kiln preheating zone through the branch conveying pipeline; the hot air distributor is arranged at the upper and lower ends of a rod in the kiln; and flow regulation gates are arranged on the hot air acquisition pipelines and the branch conveying pipeline. The hot air in the cooling zone is exhausted and is uniformly conveyed to a preheating zone in the kiln through the air distributor, so that the temperature distribution on the section of the kiln is uniform, the overall heat efficiency is improved by 5-25 percent, and the fuel is saved by 5-15 percent.

Description

technical field [0001] The invention relates to an oxygen-enriched combustion daily-use ceramic roller kiln waste heat utilization hot air preheating system, which is particularly suitable for oxygen-enriched daily-use ceramic roller kiln. Background technique [0002] Roller kiln can be used in the production of architectural ceramics, sanitary ceramics and daily ceramics. Roller kiln is a high-efficiency continuous firing kiln, using rotating sticks as the green body carrier. Ceramic products are placed on a horizontal roller table composed of several refractory rollers arranged in parallel, and the ceramics are conveyed from the kiln head to the kiln tail with the rotation of the rollers. The section of the roller kiln is generally narrow and long, and the section is small, which is suitable for rapid firing. It is mainly used for the rapid firing of daily-use ceramics and architectural sanitary ceramics. [0003] The working principle of the roller kiln is: the ceramic...
