Technical Field

[0001] The utility model relates to the technical field of artificial board production, in particular to a drying tail gas treatment device for artificial board production. Background Art

[0002] With the continuous development of social economy, people have higher and higher requirements for the quality of living environment. At present, protecting the environment has become a consensus among people, and this is also true in the manufacturing process of industrial wood. Compared with wood itself, the performance of artificial boards will be more stable after deep processing, and it is not easily affected by environmental factors such as temperature and humidity, so it has stronger anti-deformation ability. In particular, for scenes used in humid environments, artificial boards are more durable than wood, and are not easy to expand or deform due to humidity, thus ensuring the service life. Therefore, it is necessary to purify the waste gas generated by the production of artificial boards to prevent it from polluting the air;

[0003] At present, the tail gas emission of artificial board factories is basically self-emission, and the dust is filtered by filters. The main components of the tail gas of artificial board production are fiber dust, formaldehyde, volatile organic gas (VOC) and odor. In addition, the tail gas of artificial board production has a large volume, high dust content and high temperature, which will have an adverse impact on the environment.

[0004] The gas treatment technology currently available on the market cannot handle industrial exhaust gas with the characteristics of large gas volume, high dust content, high temperature and low organic matter concentration. The imported technology has high equipment cost and high operating costs, which makes the artificial board industry, which is already operating at a low profit, even worse. For this reason, we propose an exhaust gas treatment equipment for drying in the production of artificial boards. Utility Model Content

[0011] Furthermore, it also includes a drainage trough, which is opened on the left side of the bottom wall of the box body. A drainage pipe is provided at the drainage hole at the bottom of the front end of the box body. The drainage pipe is connected to the drainage trough. A drainage valve is connected in series in the middle of the drainage pipe to discharge water generated by the adjustable photocatalytic oxidation mechanism.

[0012] Furthermore, it also includes a dust box, which is arranged at the dust discharge port at the lower end of the air intake duct, and a dust receiving tray is placed inside the dust box through a bracket, and the dust receiving tray is supported by the lower end bracket, and a dust box door is hinged at the left side of the dust box through a hinge, and a handle is installed in the middle of the left side of the dust box door to store dust filtered by the air intake duct filter.

[0013] Furthermore, a single chip microcomputer is provided on the front side of the box, and an input end of the single chip microcomputer is electrically connected to an external power supply to intelligently control the rotation of the motor.

[0014] Furthermore, the adjustable photocatalytic oxidation mechanism includes a UV photocatalytic oxidation lamp, a support plate shaft and a support plate. The support plate shaft is rotatably connected to the left sides of the front and rear inner walls of the box respectively. A support plate is fixedly connected between every two corresponding front and rear support plate shafts. The interior of the support plate is provided with a UV photocatalytic oxidation lamp. The input end of the UV photocatalytic oxidation lamp is electrically connected to the output end of the single-chip microcomputer. The UV photocatalytic oxidation lamp can oxidize the exhaust gas. The support plate shaft and the support plate support the UV photocatalytic oxidation lamp.

[0015] Furthermore, the adjustable photocatalytic oxidation mechanism also includes a motor, a wheel shaft, a wheel, a connecting rod rack plate and a gear. The motor is arranged on the left side of the box, and a wheel shaft is provided on the right side of the output shaft of the motor. The wheel shaft is rotatably connected to the left end of the box.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the tail gas treatment equipment for drying of artificial board production has the following advantages:

[0018] The exhaust gas containing dust enters from the intake duct. There is a channel at the lower end of the intake duct. After being filtered by the filter screen of the intake duct, the dust falls into the channel at the lower end of the intake duct by its own weight and enters the dust box. Finally, large particles of dust fall on the dust receiving plate. The exhaust gas further enters the adjustable photocatalytic oxidation mechanism. Through the internal structure of the box and the setting of the partition, the exhaust gas is prompted to take a Z-shaped track inside the box. At the same time, the single-chip microcomputer turns on the UV photocatalytic oxidation lamp. The UV photocatalytic oxidation lamp decomposes oxygen into free oxygen and ozone through ultraviolet radiation, and then decomposes harmful gases and particulate matter into harmless substances. Since the energy of ultraviolet rays is very high, ozone and free oxygen have strong oxidizing ability, which can quickly oxidize and decompose harmful substances, ensuring that the subsequent tail gas can be fully and strongly oxidized and decomposed. At the same time, the single-chip microcomputer controls the operation of the motor, and the output shaft of the motor drives the rotor shaft and the rotor to rotate. The rack plate is pulled by the connecting rod to slide back and forth between the two slide rails, and then the rack plate and the gear are meshed and driven, and finally the UV photolysis catalytic oxidation lamp, the support plate shaft and the support plate are driven to rotate, so that the UV photolysis catalytic oxidation lamp can be irradiated without dead angles. The water and harmless gas produced by the treated tail gas enter the drainage trough respectively. The water in the drainage trough is discharged in time periods through the drainage pipe by the switch of the drainage valve. Other gases enter the leak box through the air vent, and the activated carbon particles filled in the leak box further adsorb and evolve the gas. The drying tail gas produced by the artificial board is purified and filtered through three layers, and the treatment is more thorough and comprehensive. It can treat industrial tail gas with large gas volume, high dust content, high temperature, low organic matter concentration, etc., and the cost is relatively low. BRIEF DESCRIPTION OF THE DRAWINGS
