Description

Energy-saving drying system for processing wooden product core board Technical Field The invention belongs to the technical field of woodwork processing, and particularly relates to an energy-saving drying system for woodwork core board processing. Background The wooden core board is an important component in artificial board, furniture and building decoration material, and its processing quality directly determines the performance and service life of the final product. In the production process flow of the wood product core board, drying is a vital ring, and the main purpose of the drying is to remove redundant moisture in the wood and prevent deformation, cracking or mildew and other phenomena in the later stage. At present, a commonly adopted hot air circulation drying system dries materials by heating air and convection, and although the technology is mature, in long-term application practice, the following significant defects still exist, so that the energy utilization rate is low, the maintenance cost is increased and the degree of automation is limited: 1. In order to maintain the temperature in the drying box during operation of the conventional drying system, it is generally required to continuously exhaust hot and humid exhaust air in the box and supplement fresh cool air from the outside. The discharged wet and hot waste gas carries a large amount of heat energy, but the prior art usually directly discharges the part of high-temperature waste gas into the atmosphere, and the waste heat is not effectively recovered. At the same time, the newly replenished cold air needs to consume a large amount of electrical energy or fuel to reheat to the process temperature. The mode of direct-discharge direct-compensation causes huge energy waste, so that the production cost of enterprises is high, and the method does not accord with the current industry development trend of green manufacturing, energy conservation and emission reduction. 2. In the drying process, solid impurities such as fine sawdust and dust which are stripped from wood are inevitably carried in the waste gas. These impurities are very likely to adhere to and accumulate on the heat exchange channel surfaces when flowing through the heat exchanger. Along with the extension of the running time, the impurity layer can form thermal resistance to seriously obstruct the heat exchange efficiency, and if the sawdust in the waste gas can not be effectively collected, the sawdust can be scattered in the equipment or discharged into the environment, so that the waste of materials is caused, and the operation environment is polluted. 3. The existing impurity collecting device is usually a simple storage box or a dust collecting bag, and lacks a real-time monitoring function for storage capacity. It is difficult for the operator to visually judge whether the collection container is full. If the waste gas is not cleaned in time, once the collecting container is fully loaded, impurities can overflow, the workshop environment is polluted, and even an exhaust channel is blocked, so that equipment failure or potential safety hazard is caused. Currently, most rely on manual timing inspection or experience estimation of cleaning time, and hysteresis exists. Disclosure of Invention Therefore, the invention aims to provide an energy-saving drying system for processing a wooden product core board, which can recover waste heat, save energy, automatically collect materials and overflow and warn by utilizing an airflow self-cleaning filter screen, and improve the drying efficiency and the intelligent level.
