With the rapid development of construction machinery industry, forgings play an important role in machinery manufacturing. However, in the forging process, the mold will produce a lot of exhaust gas and waste smoke, which may contain harmful substances and particles. These waste gases and smoke pose a potential threat to the environment and human health, so the problem of mold gas emission and purification is becoming increasingly prominent.
In order to reduce the impact of mold gas emissions on the environment and ensure production safety, we should take a series of measures to control and purify mold gas emissions.
First of all, in the mold design stage, we can reduce the generation of waste gas and smoke by optimizing the structure and process parameters of the mold. Reasonable mold design can reduce the production of combustion exhaust gas and particulate matter. Therefore, in the mold design process, it is necessary to take into account the emission of waste gas and smoke, and seek the best solution.
Secondly, in the forging process, we can reduce the generation of waste gas and smoke by controlling the forging temperature, heating method and material and other process parameters. Reasonable selection of fuel type and combustion equipment can effectively reduce the emission of waste gas pollutants. For example, the use of clean fuels and efficient combustion equipment can reduce the content of harmful substances in the exhaust gas.
In addition, increasing the exhaust device is also one of the most important measures. The exhaust device is set on the forging site or the mold, which can discharge the exhaust gas and waste smoke outdoors in time to avoid causing pollution to the indoor air. The exhaust device should be rationally arranged and set according to the actual situation to ensure that the exhaust gas can be smoothly discharged and ensure that the exhaust gas meets the relevant emission standards.
The cleaning treatment of mold gas is a key step to solve the problem of mold gas emission. The commonly used purification methods include dust removal equipment, waste gas treatment equipment and flue gas desulfurization and denitrification. Dust removal equipment, such as vacuum cleaners, electrostatic precipitators and bag precipitators, can filter and capture particles in the exhaust gas to achieve the purpose of purification. The waste gas treatment device can treat harmful substances in the waste gas, such as the acid and alkali waste gas treatment device, activated carbon adsorption device, etc. The sulfur or nitrogen compounds produced in the forging process can be treated by flue gas desulfurization and denitrification device to reduce the pollution to the atmospheric environment.
In addition to the above technical means, we also need to strengthen the regular maintenance and management of the mold. Regularly check and clean the mold and purification equipment to ensure its normal operation, avoid air leakage and leakage, so as to ensure the purification effect. In addition, exhaust gas monitoring equipment should be installed to monitor the concentration and composition of mold gas emissions, find problems in time and take corresponding measures. At the same time, strengthen staff training and publicity education, improve their awareness of and attention to mold gas emission and purification, enhance environmental awareness, and promote environmental protection and sustainable development of enterprises.
Therefore, the die gas emission and purification of construction machinery forging die is a complex and important problem. Only through reasonable design, scientific process control and effective purification treatment, can we minimize the impact of waste gas and waste smoke on the environment, while ensuring the safety and sustainable development of production. Only by paying attention to the problem of mold gas emission and purification can we achieve environmentally friendly forging production and contribute to sustainable development.
