Can reach the exhaust gas treatment complete set of equipment such as stainless steel spray absorption tower to solve the problem of exhaust ash and smoke from metal die-casting companies

08/25/2019 Browsing times: 168 08/25/2019

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 the upstream and downstream supporting enterprises of the exhaust gas treatment equipment. The company can win customers with good reputation, good reputation, and high cost performance. Favor. 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,包括废气处理成套设备的布置和摆放。 Noda Environment appointed professional and technical personnel to visit the customer for on-site inspection, fully understood and clarified the client's entrusted intention, and confirmed the existing conditions provided by the customer, including the layout and placement of the exhaust gas treatment equipment . In order to ensure the normal production of customers, we need to adopt the wet stainless steel spray absorption tower device treatment process. Our technical staff made detailed and vivid descriptions of equipment performance for customers from the process design perspective and the production and processing perspective, 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 spray absorption towers, 2 carbon steel centrifugal fans with supporting power of 22KW, circulating water pumps: motor power of 7.5kw, 2 demisters, and electrical control for a total of five section. 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.


Noda Environment provides the layout and installation design of all equipment, air ducts and other stainless steel spray absorption towers, and arranges the design and construction after the customer's approval. 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 automation control software, stainless steel spray absorption tower and other equipment required for the installation of all equipment and tools One-stop service for designing, manufacturing, installing, and debugging the entire waste gas treatment equipment project including hardware and spare parts.


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

After the production and debugging of the exhaust gas treatment equipment is completed, our company informs the customer to arrange staff to go to the factory to carry out the trial operation and pre-acceptance of the stainless steel spray absorption tower of the exhaust gas treatment equipment. After passing the test, it meets the technical agreement. The Noda Environmental Logistics Department arranges the equipment such as stainless steel spray absorption towers to be loaded on trucks and transported safely to the customer plant in Tianjin. 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 absorption tower working principle


The harmful exhaust gas is sucked into the pressure equalizing chamber formed by the inner and outer jackets of the lower part of the stainless steel spray absorption tower through the fan through the air duct. The bed is spray-treated, so that after the circuitous, non-constant secondary spray treatment, the gas-liquid two phases are brought into full contact to cause the absorption neutralization reaction. The second pre-spraying of the exhaust gas purification tower 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 gas-liquid two phases are in full contact to cause an absorption neutralization reaction. After the treated exhaust gas is deliquored by the upper dehydrator, it enters the stainless steel demister, and after passing through the pipeline, it is 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 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 exhaust pipe of the exhaust gas treatment equipment needs to be resistant to high temperature, explosion-proof, anti-corrosion, anti-aging and anti-ultraviolet; and all carbon steel centrifuges and spray towers need to be resistant to high temperature; all equipment including power parts must have safety protection .


5. The stainless steel spray absorption 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 of the exhaust gas discharged by Party A to the outdoors, and no exhaust gas, waste smoke backflow, etc. shall occur, and the indoor odor will not appear.


7. All dampers of the exhaust gas treatment equipment should be easy to open or close, and there should be no difficult operation, jamming, leakage, etc .;


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


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 air pollutants, and the overall indoor environment meets the "National Occupational Health Standard of the People's Republic of China" GBZ2.1-2007, reaching GB16297 -1996 "Integrated Emission Standard for Air Pollutants" emission standards. 薛先生13706116059 (同微信) Noda Environment keeps improving on the waste gas treatment process.
