Description

Technical Field

[0001] The invention relates to the technical field of waste gas combustion furnaces, in particular to a self-adaptive adjustment mechanism for a preheater orifice plate of a direct-fired TO furnace. Background Art

[0002] The gluing machine will inevitably produce organic waste gas during the production process. The potential harm of these waste gases to the environment and human health cannot be ignored. In order to reduce this harm, we need to treat the waste gas into harmless gas to meet the emission standards. Since many waste gases are gaseous organic compounds, the incineration process has become a common, effective and low-cost waste gas treatment process. The high-temperature waste gas after incineration treatment can not only effectively reduce the emission of organic waste gas, but also can be used as a new type of energy, which has dual environmental protection and economic benefits.

[0003] However, in the process of waste gas treatment, when the direct-fired TO furnace is treating combustion waste gas, the orifice plate in the preheater is usually installed in a fixed manner. This installation method is prone to deformation of the orifice plate during long-term use, especially in the case of thermal expansion and contraction. Since the internal stress caused by thermal expansion and contraction cannot be eliminated, the orifice plate will experience stress concentration under the condition of repeated alternation of hot and cold working conditions, and then cracking will occur. This not only affects the service life of the preheater, but may also lead to a decrease in the waste gas treatment effect, increasing the potential risks to the environment and human health.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop an adaptive adjustment mechanism for the orifice plate of a direct-fired TO furnace preheater. Summary of the invention
