The company attaches great importance to environmental protection while vigorously improving the economic benefits of the enterprise and paying attention to product quality. The company's leaders, in line with the principle of creating a good production and living environment for the employees and the surrounding residents, collect and process the gas generated in the operation process and completely eliminate the hidden dangers of the enterprise's development. Entrusted by the company, shandong baolan environmental protection engineering co., LTD. Based on the design principle of mature and reliable technology, reasonable overall layout, convenient operation and management, and low processing cost, we have compiled this scheme.
According to the information provided by your company, the main exhaust gas source is asphalt flue gas, which contains a variety of organic matters, including carbon cyclic hydrocarbons, cyclic hydrocarbon derivatives and other compounds, many of which are harmful to human health.
The composition of bitumen flue gas is very complex and varies with the source of bitumen. In the flue gas of asphalt, there are both solid and liquid particles condensed from volatile components of asphalt, and organic matter in vapor state.
Smoke contains a variety of organic compounds, including carbon hydrocarbon, hydrocarbon derivatives and other compounds, many have harmful effects on health, asphalt smoke contain benzopyrene, benzene and anthracene and carbazole polycyclic aromatic substances, and are mostly carcinogenic and is strong carcinogens, particle size between 0.1 ~ 1.0 microns, the smallest is only 0.01μm, the largest of about 10.0μm, it is a delegate with 3, 4 - benzopyrene many carcinogens. The main route of its harm to human health is to adhere to the dust below 8um, which is absorbed into the body through the respiratory tract.
First of all, according to the physical and chemical properties of dust, combined with our company's years of experience in dust treatment, and considering the effect of dust treatment, process investment and operating costs, our company plans to adopt the "bag filter + fan + chimney. For effective dust treatment.
Secondly, considering the operating cost and safety of the waste gas treated in this project, the process route of this project adopts "electric tar catcher + composite optoxic equipment" as the core process to treat the waste gas. The process route diagram:
Introduction to the process:
As a first step, after collecting the asphalt smoke entering into the electric tar precipitator, when the flue gas through the dust and tar material in the flue gas is in the charge under the action of ionization, to charge with wire and tube wall motion, and loss of charge, when the adsorption on precipitation in the miscellaneous quality increases to greater than its adhesion, under the action of gravity, automatically downflow, from electric catching tar bottom discharge, net gas is from upper left of the electric tar precipitator and into the next procedure, hence leading to the degradation of pollutants removal.
The second step, after capturing fumes into composite optical oxygen equipment, in the device, high energy photon beam ozone reacts with air and · OH (hydroxyl radicals) oxidation reaction of fetor synergy decomposition, and macromolecular odorous gases under the effect of high-energy photons make its chain structure fracture, make the most of the organic material into a gas no stink of small molecular compound or mineralized completely, formation water and CO2. Exhaust gas into the zeolite molecular sieve layer deep purification, and finally through the fan pipe chimney discharge standards.
