Description

Technical Field

[0001] This application relates to the technical field of wood-based panel production, and particularly to an automated production system for formaldehyde-free wood-based panels. Background Art

[0002] Wood-based panel, made from wood or other non-wood plants as raw materials, after being mechanically processed into various unit materials, is glued with or without adhesives and other additives to form panels or molded products. It mainly includes three categories of products: plywood, particle (chip) board, and fiber board, and its extended products and deep-processed products can reach more than a hundred kinds. The birth of wood-based panels marks the beginning of the modernization period of wood processing, changing the process from simply changing the shape of wood to improving the properties of wood. This development not only involves all wood processing technologies but also requires absorbing technologies from fields such as textile and papermaking to form independent processing technologies. In addition, wood-based panels can improve the comprehensive utilization rate of wood. 1 cubic meter of wood-based panel can replace 3 - 5 cubic meters of log. However, formaldehyde is often generated during the production of wood-based panels, so it is necessary to monitor and remove the formaldehyde concentration during the production process.

The collection module includes a formaldehyde detector, and the formaldehyde detector is used to detect the formaldehyde data in the wood-based panel production workshop in real time; the cloud platform control module receives the formaldehyde data and transmits it to the processor. The processor processes and calculates the formaldehyde concentration in the wood-based panel production workshop according to the formaldehyde data, obtains formaldehyde concentration data, then compares the formaldehyde concentration data with the formaldehyde concentration safety limit value to obtain a comparison result, and sends a control instruction to the controller according to the comparison result; the controller is used to receive the control instruction and control the aldehyde removal equipment to perform aldehyde-free treatment according to the control instruction, realizing automatic real-time monitoring of the formaldehyde concentration in the wood-based panel production workshop and timely removing aldehyde, avoiding the harm of formaldehyde to the personnel in the production workshop, and improving the production efficiency of wood-based panels.

[0026] Further, the calculation formula for the processor to process and calculate the formaldehyde concentration in the wood-based panel production workshop according to the formaldehyde data is:

[0027]

[0028] Where J is the formaldehyde concentration, M is the formaldehyde molecular weight in the formaldehyde data, T is the temperature in the workshop, and P is the atmospheric pressure;

[0029] Specifically, at normal temperature (about 25°C) and standard atmospheric pressure, 1 ppm formaldehyde ≈ 1.25 mg / m3. For example, when the formaldehyde detector shows 0.1 ppm, the corresponding concentration is 0.125 mg / m3.

[0030] Further, the aldehyde removal equipment is used to spray a formaldehyde scavenger on the produced wood-based panels. The formaldehyde scavenger is composed of attapulgite, tea polyphenols, amino acids, sodium sulfate-hydrogen peroxide-sodium chloride adduct, anatase titanium dioxide, and a penetrant; thus, aldehyde-free treatment of the produced wood-based panels is realized, and the efficiency of aldehyde-free treatment of wood-based panels is improved, that is, aldehyde-free treatment of the produced wood-based panels is carried out by spraying a formaldehyde scavenger with an automatic aldehyde removal device, improving the efficiency of formaldehyde removal in wood-based panels.

[0031] Specifically, mix attapulgite, tea polyphenols, amino acids, sodium sulfate-hydrogen peroxide-sodium chloride adduct, anatase titanium dioxide, and a penetrant and stir evenly to obtain the formaldehyde scavenger of the present invention;

[0032] Among them, attapulgite, also known as palygorskite or palygorskite, is a hydrous magnesium-rich silicate clay mineral with a chain layered structure. Its structure belongs to the 2:1 type clay mineral. In each 2:1 unit structure layer, the corners of the tetrahedral wafer are reversed at a certain distance to form a layer chain.

[0033] Tea polyphenols, also known as antioxidant, vitamin phenol, and anti-haring, are a type of polyhydroxy compounds contained in tea leaves, referred to as TP. The main chemical components are a complex of catechins (flavanols), flavonoids and flavonols, anthocyanins, phenolic acids and phenolic acids, polymerized phenols and other compounds. Among them, catechins are the main components of tea polyphenols, accounting for 65% to 80% of the total tea polyphenols.

[0034] Amino acid is a general term for a class of organic compounds containing amino and carboxyl groups. It is the basic building block of biological functional macromolecular proteins and the basic substance that constitutes the protein required for animal nutrition. The amino acid is one of alanine, tryptophan, L-aspartic acid, histidine, lysine, glutamic acid, methionine, proline, threonine, leucine, arginine, lactamase, glycine and L-homoserine or a mixture thereof. Optimally, the amino acid is a mixture of L-aspartic acid and L-homoserine, wherein the mass ratio of L-aspartic acid to L-homoserine is 2:1-1:2;

[0035] Sodium sulfate-hydrogen peroxide-sodium chloride adduct, also known as solid hydrogen peroxide, has bleaching, sterilization, disinfection and other functions, and has mild oxidation performance, is non-toxic and pollution-free. As a neutral and non-toxic washing aid, it has more advantages than alkaline peroxides such as sodium percarbonate, sodium perborate, sodium superphosphate, etc., and has lower production cost, more convenient and stable storage and transportation, safer and milder oxidation performance, better use effect and environmental protection performance. The preparation process can be: adding sodium chloride to hydrogen peroxide solution, then adding anhydrous sodium sulfate, stirring, reducing pressure and filtering, and vacuum drying to obtain sodium sulfate-hydrogen peroxide-sodium chloride adduct;

[0036] Anatase titanium dioxide has a good photocatalytic effect. It can decompose harmful gases and some inorganic compounds in the air, inhibit bacterial growth and viral activity, and achieve air purification, sterilization, deodorization, and mildew prevention.

[0037] Furthermore, the formaldehyde removal equipment also includes an exhaust device, which is used to absorb the formaldehyde in the artificial board production workshop to the outside, thereby improving the formaldehyde removal efficiency of the artificial board production workshop, preventing personnel in the production workshop from being harmed by formaldehyde, and improving the production efficiency of artificial boards.

[0038] Further, the acquisition module includes a temperature acquisition module for the equipment control cabinet, which is used to acquire the real-time temperature data of the equipment control cabinet in the wood-based panel production workshop, and transmit the real-time temperature data of the equipment control cabinet to the cloud platform control module through the network data transmission module. The temperature acquisition module for the equipment control cabinet includes a plurality of non-contact temperature sensors, and the plurality of non-contact temperature sensors are respectively arranged on the line busbars and the top of the equipment control cabinet; the cloud platform control module is used to transmit the received real-time temperature data of the equipment control cabinet to the processor; the processor compares the real-time temperature data with the preset temperature data to obtain a comparison result. When the comparison result is that the real-time temperature data is greater than the preset temperature data, the processor sends a danger signal to the controller, and the controller controls the operation of the equipment control cabinet according to the danger signal. Specifically, when the controller receives the danger signal sent by the processor, the controller connects to the corresponding equipment control cabinet and controls the processing equipment of the wood-based panel to stop working through the corresponding equipment control cabinet, so as to avoid equipment failures caused by abnormal environmental parameters in the equipment control cabinet, and the operation status of the processing equipment can be remotely and online monitored.

[0039] It further includes an intelligent management terminal module, which provides an operation terminal for the managers of the processing equipment.
