A cycle energy-saving heating system for bamboo and wood products production line

Abstract

The invention discloses a circulation energy-saving heating system for a bamboo and wood product production line. The circulation energy-saving heating system comprises a heater; the heater is a combustion furnace; a tail gas tube of the combustion furnace is connected with an insulation sleeve; the insulation sleeve is arranged outside an oil collection tube, is connected with a heat exchanger through a pipeline and discharges tail gas into waste heat; the heat exchanger is also provided with an air inlet tube and a heating tube; the heating tube is divided into a front air duct and a back air duct; and the front air duct and the back air duct are connected with an air pipeline of a hot air machine and an air pipeline of a micro hot air machine respectively. According to the circulation energy-saving heating system, the tail gas waste heat of the heater is utilized to carry out heat preservation on returned oil so as to enable the temperature of the returned oil to be proper; tail gas enters the hot air machine after being subjected to heat exchange, so that the whole energy consumption of the hot air machine is lowered; and clean hot air which passes through an oil collection chamber rushes into oil in a filter tank, so that impurity adsorption and aggregation of micro particles are accelerated, and the filter effect is improved.

Description

technical field [0001] The invention relates to the technical field of bamboo and wood product oil treatment technology, in particular to a cycle energy-saving heating system for a bamboo and wood product production line. Background technique [0002] Cooking with tung oil can make the tung oil penetrate into the wood more fully, so that the wood is not easy to crack and the consistency is better. However, it is actually found that the heating system of this production line is set separately, and the exhaust heat of the heater cannot be used, and the hot air blower is used every day. It consumes more energy, and at the same time, there are more fine impurities in the oil return. Therefore, how to unify these three shortcomings, design a set of process and equipment, and solve them collectively is a technical difficulty. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a cycle energy-saving he...
