Can reach stainless steel absorption tower and other waste gas treatment equipment to solve the problem of waste gas, ash and smoke from metal die casting companies

This order comes from an exhaust gas purification project of a metal die-casting company in Tianjin. The customer asked about the technical strength of various suppliers in the industry from upstream and downstream supporting enterprises of exhaust gas treatment equipment. The company can win the favor of customers with its good reputation, good reputation, and high cost performance. . The waste gas of this waste gas purification project is mainly waste ash, waste gas and waste smoke generated during the operation of the ash stirrer and melting furnace. The waste gas generated during the operation of the project is the melting waste gas (including smoke and dust, Fluoride, etc.) and waste gas from hot air combustion, dust from the ash roasting process, dust from raw material pre-treatment process, and waste gas from holding furnace.


  委派专业技术人员赴客户实地考察之后,充分了解和明确客户的委托意图,确认了客户提供的现有条件,包括废气处理设备的布置和摆放。 Noda Environment appointed professional and technical personnel to visit the customer on site, fully understood and clarified the client's entrusted intention, and confirmed the existing conditions provided by the customer, including the layout and placement of exhaust gas treatment equipment . In order to ensure the normal production of customers, we need to adopt the wet stainless steel spray tower device treatment process. Our company's technical staff made detailed and vivid descriptions of equipment performance for customers from the perspective of process design and production and processing, and won unanimous approval from customers.


2台、配套功率22KW的碳钢离心风机2台、循环水泵:电机功率7.5kw、除雾器2台以及电气控制共五部分。 Nengda Environment decided to use in this exhaust gas purification project: 2 stainless steel absorption towers, 2 carbon steel centrifugal fans with a supporting power of 22KW, circulating water pumps: motor power of 7.5kw, 2 demisters, and five parts of electrical control. Among them, the electrical control device is designed and arranged according to the actual circuit situation of the customer to meet the functional needs of the overall degassing equipment control. Including the selection and number of components, the number and size of electrical cabinets, and circuit layout plans. The exhaust gas treatment equipment has an air volume of 50000m3 / h and a treatment concentration of not less than 400mg / m3.


Nengda Environment provides the layout and installation design of all equipment, air ducts, such as stainless steel spray towers, and arranges the design and construction after being approved by the customer. The equipment used is provided, the construction design drawings of the pipelines, and the installation and commissioning of all equipment and air pipelines are the responsibility of Noda Environment. The purchased parts and components used in the project are all new well-known brands, and the purchased parts are reported to customers for the record. Noda Environment provides customers with exhaust gas treatment equipment design drawings, consumables atlas, operating procedures, electrical diagrams, PLC programs, as well as automatic control software, stainless steel spray towers and other equipment required for the installation of all equipment and consumable spare parts And other hardware, design, production, installation and commissioning of the overall exhaust gas treatment equipment project.


After more than ten days of meticulous production, the exhaust gas treatment equipment: the prototype of the stainless steel spray tower has appeared

After the exhaust gas treatment equipment production and commissioning is completed, our company informs the customer to arrange staff to go to the factory to carry out trial operation and pre-acceptance of the stainless steel spray tower of the exhaust gas treatment equipment. After passing the test, it meets the technical agreement. The Noda Environmental Logistics Department arranges the loading and transportation of stainless steel spray towers and other equipment to the Tianjin customer factory. After installation and commissioning, our company's engineers instructed and trained customer operators on site to conduct trial production. After 15 days of continuous and stable operation, formal acceptance was conducted.

Stainless steel spray tower working principle


The harmful exhaust gas is sucked into the pressure equalizing chamber formed by the fan through the air pipe into the inner and outer jacket of the lower part of the stainless steel spray tower. After a pre-spray, it enters the packed bed of the inner cylinder processor for pre-spray treatment, and then enters the upper packed bed at a low speed. The spray treatment is performed, so that after the circuitous, non-constant secondary spray treatment, the gas and liquid phases are brought into full contact to cause the absorption and neutralization reaction. The treated exhaust gas is deliquored by the upper dehydrator, and then passes through the second unit. The exhaust gas purification tower is pre-sprayed twice and enters the packed bed of the inner cylinder processor for pre-spraying treatment, and then enters the upper packed bed at a low speed for spraying treatment. The two phases of the liquid are fully in contact with each other to cause absorption and neutralization reaction. The treated exhaust gas is deliquored by the upper dehydrator, enters the stainless steel demister, and passes through a pipe to be discharged into the atmosphere by a fan.

The exhaust gas treatment equipment designed and produced by Noda Environment meets the following requirements


散发源的区域内的大气环境不受废气污染; 1. During the process of waste gas collection, extraction, and transportation, the exhaust gas must not escape, and the atmospheric environment in areas other than the source where the waste gas is emitted , such as the operating room and the duty room, is not polluted by the exhaust gas;


2. After passing the exhaust gas treatment equipment, the required treatment effect must be achieved. 中,且达到三级排放标准; The purified air can be directly discharged into the atmosphere and meets the third-level emission standard;


3. The layout of the exhaust pipe of the exhaust gas treatment equipment is reasonable and beautiful, and shall not affect the normal production of Party A;


4. The material of the duct of the exhaust gas treatment equipment should be resistant to high temperature, explosion-proof, anti-corrosion, anti-aging and anti-ultraviolet; and all carbon steel centrifugal extensions and spray towers need to be protected from high temperatures; all equipment including power parts must have safety protection devices.


5. The stainless steel spray tower of the exhaust gas treatment equipment shall not have foam overflow phenomenon, and all pipe joints shall not have water leakage or gas leakage;


6. The exhaust gas treatment equipment should be able to discharge all the exhaust gas discharged by Party A to the outdoors, and there should be no exhaust gas, waste smoke backflow, etc., and there should be no odor in the room;


7. All dampers of the exhaust gas treatment equipment should be convenient to operate when opened or closed, and should not be difficult to operate, jammed, leaked, etc .;


8. The exhaust gas treatment equipment should be able to meet and meet the testing requirements of environmental protection departments.


Exhaust gas treatment is completed by a set of exhaust gas treatment equipment (placed outdoors). The fan can adjust the operating speed according to needs. All dampers are manually operated. The exhaust chimney of the exhaust gas treatment equipment uses the customer's existing chimney design to arrange construction.


After using the exhaust gas treatment equipment designed and produced by Noda Environment for one month, the treated exhaust gas meets the comprehensive emission standards for atmospheric pollutants, and the overall indoor environment meets the National Occupational Health Standard of the People's Republic of China GBZ2.1-2007, reaching GB16297- Emission standard of 1996 "Integrated Emission Standard of Air Pollutants". 薛先生13706116059 (同微信) Noda Environment keeps improving on the waste gas treatment process.
