Description

Combustion-supporting air exhausting device of double-chamber kiln Technical Field The utility model belongs to the technical field of double-chamber kilns, and particularly relates to a combustion-supporting air exhaust device of a double-chamber kiln Background When the double-chamber kiln is reversed, the pressure in the kiln is required to be released, and the double-chamber kiln is completed by a primary release valve of a 35M platform and a secondary release valve of an 11.4M platform. Referring to fig. 1 and 2, when the double-hearth kiln is subjected to reversing pressure relief, the primary release valve 7 discharges the combustion air 100 to the waste gas dust removal pipeline 4, and the secondary release valve 8 directly discharges the combustion air 100 to the atmosphere. In actual operation, the primary release valve 7 adopts a hard sealing mode, the sealing effect of the sealing valve is poor, air leakage is easy, the pressure fluctuation in the kiln is large in the production process, the product quality is affected, and the valve is often required to be maintained by spot inspection with less consumption of manpower and material resources. Therefore, improvement is needed when reversing and depressurizing the double-hearth kiln, and combustion supporting air of the double-hearth kiln is effectively released. Disclosure of utility model The utility model aims to provide a combustion-supporting air exhaust device of a double-hearth kiln, so as to overcome the technical defects in the background technology. The specific technical scheme is as follows: the utility model provides a two thorax kiln combustion-supporting wind exhaust apparatus, includes the combustion-supporting wind pipeline, the both ends of combustion-supporting wind pipeline are connected with switching-over valve and relief valve respectively, the switching-over valve is connected with waste gas dust removal pipeline, the relief valve is connected to combustion-supporting wind release pipeline, the combustion-supporting wind release pipeline is connected to waste gas dust removal pipeline, be connected with the air current buffer assembly in the combustion-supporting wind release pipeline, the air current buffer assembly is used for changing the air current direction in the combustion-supporting wind release pipeline. Preferably, the combustion-supporting air release pipeline comprises a release pipeline, a bent pipeline and a buffer pipeline which are connected with each other in sequence, wherein the release pipeline is horizontally arranged and then connected with the release valve, and the buffer pipeline is vertically arranged and then connected with the waste gas dust removal pipeline. Preferably, the air flow buffer assembly is arranged in the buffer pipeline. Preferably, the length of the buffer pipe is 10mm or more.
