Description
Technical Field
[0001] The utility model relates to the technical field of waste heat recovery and utilization, in particular to a heat recovery and utilization device for a particleboard production line. Background Art
[0002] Particleboard is also called particle board. It is a kind of man-made board made by cutting various branches, small-diameter wood, fast-growing wood, sawdust, etc. into pieces of certain specifications, drying them, mixing them with glue, hardener, waterproofing agent, etc., and pressing them under certain temperature and pressure. The particles are arranged unevenly. Particleboard has good sound absorption and sound insulation performance; the internal structure is cross-staggered particles, and the performance of each direction is basically the same; the surface is flat and can be veneered in various ways; in the production process, the amount of glue used is small, and the environmental protection coefficient is relatively high. Therefore, the popularity of particleboard is very high.
[0003] Some wood shavings drying production lines mainly include a screening mechanism, a material conveyor, an elevator, a wood shavings drying equipment and a dust collector connected in sequence. The wood shavings drying equipment uses the high-temperature flue gas generated by the boiler as the drying heat medium, and the fan provides the conveying power of the wood shavings and the flue gas. After the wet wood shavings are dried by the drying equipment, they are separated by a cyclone separator or discharged from the blanking box. The tail gas generated by the boiler contains a large amount of waste heat. The existing wood shavings drying equipment directly discharges the boiler tail gas after dust removal through a bag filter. Due to the large discharge volume, the waste heat in the tail gas is also wasted in large quantities. For this reason, the Chinese patent (authorization announcement number: CN216868948) proposes a wood shavings drying production line with a tail gas waste heat pre-drying device. The patent adds a pre-drying device to recycle the tail gas generated by the boiler in the original wood shavings drying production line, and pre-dry the wet wood shavings using the tail gas waste heat, thereby reducing the moisture content of the wet wood shavings and alleviating the drying pressure of the wood shavings drying equipment, thereby saving boiler fuel and electricity consumption. The utility model is mainly used for wood shavings drying.
[0004] However, the high-temperature flue gas generated by the above-mentioned patented boiler still has residual heat after entering the pre-drying drum for drying and discharge, and the recycling effect is not strong. In order to improve the heat recovery effect of the particleboard production line, we propose a heat recovery device for the particleboard production line. Utility Model Content

By heating the inside and the outside at the same time, the heating effect of the water in the recovery inner shell can be improved, and the heated water in the recovery inner shell can be used as water for the boiler. Before the water enters the boiler, the waste heat of the boiler water can be used to improve the heating effect of the boiler, and the water in the recovery inner shell can be used as part of the domestic water in the factory area.
