Our company combined with advanced waste gas treatment technology, industrial waste gas such as ammonia, hydrogen sulfide, formaldehyde and other odor waste gas treatment, to meet the national industrial waste gas emission standards. Biological deodorant tower is mainly used in petrochemical, medicine, printing and dyeing, machinery, food, metallurgy and other industries and fields.
Biological deodorization and purification tower working principle
The biological filter bed deodorization process is a method to remove odor by biological method. Compared with the traditional physical and chemical treatment method, the biological method has the advantages of avoiding or reducing secondary pollution, less long-term investment, low energy consumption, low operating costs, simple device and high deodorization efficiency, and the deodorization efficiency is greater than 90%.
The biological filter bed deodorization tower is mainly to adsorb, absorb and degradation organic matter by the biological filter bed attached to the microbial membrane, use it as the energy or carbon resource material required for its own growth and metabolism, and eventually transform into CO2, H2O and other odorless, non-toxic, harmless simple inorganic substances, to achieve the purpose of removing odor, and finally achieve the purification effect. In order to achieve the ideal deodorization treatment, the biofilter system must be fully automated.
Performance characteristics of biofilter bed deodorizing tower
1, waste gas treatment equipment has a wide range of applications: petrochemical, chemical, light industry, printing and dyeing, medicine, steel, machinery, electronics, instrumentation, electroplating and other industrial sectors in the production process of the emission of odor gas, its treatment effect is excellent.
2, high efficiency of waste gas purification: filter bed packing of purification tower adopts high quality and efficient composite packing, equipped with humidification and temperature control, daily humidification, winter heating. The gas ratio determined by the experimental study ensures the stability of the performance, and the purification efficiency of various odor waste gas can reach 95%~99%.
3. Low resistance of waste gas treatment equipment: On the basis of ensuring sufficient gas-liquid contact area, the waste gas purification tower selects the packing varieties and structural forms with the best aerodynamic characteristics, so that the equipment resistance does not exceed 40 mm water column under the rated air volume, which is the lowest resistance in various domestic packing.
4, the waste gas treatment equipment covers a small area: the waste gas purification tower is made of FRP material, the tower body, the absorption tank, the circulation pump, the absorption liquid pipeline system is combined into a complete set of industrial waste gas treatment equipment, compact structure, easy to install and operate the management of the site, the floor area is small, whether it is for new projects or technical transformation projects can be adapted.
Biofilter bed deodorant tower use precautions:
1, before use, check whether the pipe valves of the system of the equipment are in good condition, and turn on the water pump 3-5 minutes after starting the fan. When shutting down the purification system, the fan should be shut off for 2-3 minutes and then the pump should be shut off. It can not be opened randomly, otherwise it will burn out the motor, block the filler, and affect the purification effect.
2, fan and pump wiring can not be arbitrarily moved, should absolutely ensure that their steering is correct, not reverse, otherwise it will damage the motor, and can cause accidents.
3, after the delivery of the equipment, the user should assign a special person to keep the use, regular inspection, found abnormal sound or water leakage of the equipment, should be stopped and repaired before use.
4, after running for a period of time, please pay attention to check whether the inside of the liquid storage tank is clean, and clean it if necessary. When adding water to the liquid storage tank, attention should be paid to the amount of water, when the amount of water is too much or too little, it will affect the use effect. In general, the PH of the bacterial layer in the biological filter is 6 to 8, and the pH of the fungal layer is maintained between 3 and 6.
5, our company uses efficient and affordable nutrients by adding water into the culture medium. The effective deodorant can be obtained by adding the bacteria into the culture medium and incubating at an appropriate temperature for 72h. The preparation method is simple and easy, and no complex preparation equipment is required. Through the decomposition of odor substances such as ammonia, hydrogen sulfide, methyl mercaptan, the malignant reproduction of harmful microorganisms is inhibited, the production of odor substances is reduced, and the function of deodorizing and repellent mosquitoes and flies is achieved.
