Description

Technical Field

[0001] The invention relates to a drying oven waste gas recycling device, belonging to the technical field of waste gas recycling. Background Art

[0002] During the use of the oven, some waste gas will be generated. Direct discharge of these waste gases will cause great pollution to the air. In the Chinese patent application number CN201620835741.6, an oven with a waste heat recovery device is proposed. The waste heat recovery device can improve resource utilization and reduce the thermal pollution of the discharged waste gas; this structure is more environmentally friendly, energy-saving and safe; a burner and an air heater are added to the outside, so that the drying process in the oven can be carried out by the original thermal oil heat exchanger, or by burning natural gas with an air heater. There are multiple ways to use it, which can be selected according to needs; an annular body is arranged inside the air heater, and the outer end of the annular body and the inner end of the box form an annular channel, so that the air entering the box can flow along the annular channel, from The evenly distributed air enters the annular body through the air inlet hole. The setting of the annular body is mainly to allow cold air to enter the annular body from all sides, so that there is the same air intake volume around the flame of the burner. The air surrounds the flame of the burner, increasing the contact area between the cold air and the flame, stabilizing the flame of the burner, and avoiding the flame from being extinguished or insufficiently contacting with the air; a central control cabinet is set, and each oven is equipped with a PDM control unit. It adopts single-system multi-unit partition control, which is convenient to control and has a high degree of automation. The oven of the waste heat recovery device proposed in the above-mentioned comparative document cannot reuse the heat in the fiber drying process, the fiber crystallinity is not ideal, the fiber rigidity and elasticity are not ideal, and it does not have a filtering structure. Some of the filtering structures require frequent manual replacement of the filter element, which is more cumbersome.
