High-efficiency heat energy utilization structure in the drying zone of the ceramic kiln

Abstract

The invention discloses a high-efficiency heat energy utilization structure in the upper drying area of ​​a ceramic kiln. Along the upper part of the small part behind the kiln in the drying area, a box-type combined dehumidification channel is provided, which includes the A dehumidification channel in the middle and There are two B dehumidification passages juxtaposed on the left and right; along the bottom of the small part behind the kiln in the drying area, there is a box-type combined heat supply passage, which includes the A heat supply passage in the middle and the two B supply passages juxtaposed on the left and right. The heat channel, the two B heat supply channels pass through several heat supply pipes respectively, and are connected with the inner cavity of the kiln in the drying area on the left and right sides of the kiln in the drying area; along most of the upper part of the front of the kiln in the drying area, there is a The whole C dehumidification channel; along the bottom of most of the front of the kiln in the drying area, there is a whole C heating channel. The above-mentioned structure has a high heat utilization rate, can effectively prevent heat loss, and can avoid waste gas leakage, thereby achieving good energy-saving and environmental protection effects.

Description

technical field [0001] The invention relates to a ceramic kiln, in particular to a high-efficiency heat energy utilization structure for a drying area on the ceramic kiln. Background technique [0002] The ceramic kiln includes drying area, dehumidification area, preheating area, firing area, rapid cooling area, slow cooling area and fast cooling area at the end of the kiln in sequence. The dehumidification channel is a separate one. In this way, the clean hot air transmitted from the hot air channel at the bottom of the kiln in the dehumidification area, after entering the heating channel, can only be sent to the inner cavity of the kiln in the drying area through the heat supply pipe. Due to the drying effect, it cannot be diverted for the oxygen-increasing combustion of the ceramic spray drying tower and the hot blast stove, and the heat utilization rate is not high. At the same time, the humid and hot exhaust gas drawn from the dehumidification area that can be comprehen...

[0002] The ceramic kiln includes drying area, dehumidification area, preheating area, firing area, rapid cooling area, slow cooling area and fast cooling area at the end of the kiln in sequence. The dehumidification channel is a separate one. In this way, the clean hot air transmitted from the hot air channel at the bottom of the kiln in the dehumidification area, after entering the heating channel, can only be sent to the inner cavity of the kiln in the drying area through the heat supply pipe. Due to the drying effect, it cannot be diverted for the oxygen-increasing combustion of the ceramic spray drying tower and the hot blast stove, and the heat utilization rate is not high. At the same time, the humid and hot exhaust gas drawn from the dehumidification area that can be comprehensively utilized can only pass through the kiln in the drying area. The upper pipes are transmitted in the state of heat exchange with the external air, which will cause a large amount of heat loss, and a small amount of exhaust gas will leak from the pipes during transmission, causing air pollution
