Nengda Environment "Explosion-proof wet dust collector, activated carbon adsorption equipment, welding and polishing workbench" Solve the aluminum polishing and welding dust removal and exhaust gas treatment problems of a furniture company in Changzhou

,我公司委派技术人员去客户现场实地考察,相关领导热情地接待了我们。 This order came from a dust removal and exhaust gas treatment project of a furniture company in Changzhou. We found the Noda environment through customer introductions. Our company assigned technical staff to visit customers at the site and related leaders warmly welcomed us.

During the communication process, the customer proposed that they mainly produce aluminum alloy furniture for export, and the dust and organic waste gas generated during the production process exceeded the pollution standards, causing the EIA to fail. The current aluminum grinding and welding workshops and plastic spray drying rooms are in urgent need of dust and exhaust gas treatment, respectively. Nengda environmental engineers listened to the problems currently encountered by customers, diagnosed them on the spot, and analyzed the reasons for the failure of the furniture factory's environmental assessment:

1. The dust pollution generated during the machining process of grinding and polishing of aluminum alloy parts in the production workshop.

2. Welding fume and dust pollution generated during component assembly and welding.

3. The surface treatment of furniture is mainly plastic spraying. During the spray-drying process, the organic waste gas generated causes double harm to the human body and the environment.

After analyzing the reasons for the failure of the EIA, the engineer was commissioned by the customer to carry out preliminary surveys such as survey and measurement records at the grinding workshop, welding workshop and plastic spraying workshop. The mature experience, submitted a reasonable, economical and effective overall solution, won the affirmation of customers, and ultimately successfully signed the order.

The project is located in Changzhou City, Jiangsu Province, with convenient transportation. 、 活性炭吸附设备焊接打磨工作台 。 During the smooth progress of production, the client and his party personally came to our company's production site, accompanied by staff from the technical department, production department and quality control department, and inspected the products used in this cooperation "Dust Removal and Waste Gas Treatment Project" in detail: Explosion-proof wet dust collector , activated carbon adsorption equipment , welding and polishing workbench . Conduct face-to-face communication on each link of the three types of equipment, and discuss the operation and use precautions of the furniture industry. During the on-site inspection, the customer was given a thumbs-up by being able to reach an environmentally sound technical solution, excellent processing equipment, and rich engineering management experience.


Explosion-proof wet dust collector, activated carbon adsorption equipment, welding and polishing workbench technology route


进行处理,该系统的组成可分为六个部分:湿式除尘器、防爆风机、控制系统、设备吸尘罩、打磨吸尘台、风管和其他机械附件。 According to the characteristics of dust and exhaust emissions of customers' furniture companies, Noda Environment is a dust explosion dangerous place due to mechanical processing of aluminum products. Therefore, in accordance with relevant national standards and specifications and combined with the production characteristics of users, Noda Environment adopts explosion-proof for aluminum grinding and polishing dust. The wet dust collector is used for processing. The composition of the system can be divided into six parts: wet dust collector, explosion-proof fan, control system, equipment dust cover, polishing dust table, air duct and other mechanical accessories. The exhaust gas from plastic spray drying belongs to volatile organic compounds (VOCs) and is processed by exhaust gas filtration + activated carbon adsorption process. It is mainly composed of suction hood, activated carbon adsorption equipment, explosion-proof fan, air duct and other mechanical accessories. Welding fume is mainly purified by a mobile welding and polishing workbench. The entire system uses less energy to achieve compliance emissions.


The production department workers intensively produced for more than ten days, and the explosion-proof wet dust collector has begun to take shape in the production workshop.

Explosion-proof wet dust collector, activated carbon adsorption equipment, welding and polishing workbench three types of equipment lasted one month, and the production was officially completed as scheduled. The inspectors of Noda Environmental Quality Control Department conducted a comprehensive pre-factory inspection on the three sets of equipment, fully meeting the various indicators, and allowed to leave the factory.

Noda Environment arranged the technology and installers to go to the customer's factory with the car. A total of 6 sets of explosion-proof wet dust collectors, activated carbon adsorption equipment, and welding and polishing workbenches arrived at the customer's site. Materials, etc., confirm that all equipment meets the requirements specified in the contract and technical agreement.

Noda Environment is responsible for the on-site installation and commissioning of turnkey work. On-site installation and commissioning personnel strengthen the quality management, pay attention to the safety of the construction, and stand in the customer's perspective for the sake of the customer. Methodically speed up the installation and shorten the construction period for the customer.

After the explosion-proof wet dust collector, activated carbon adsorption equipment, welding and polishing workbench are successfully installed, the single machine (such as high-efficiency dust collector, fan, etc.) runs normally.

After the on-line debugging is completed, the parameters such as the explosion-proof wet dust collector, activated carbon adsorption equipment, welding and polishing workbench processing capacity, and emission indicators are tested. The results meet the inspection indicators of the technical agreement, and the system is qualified.

At the same time, we have compiled the manuals of all the equipment for you to read. If you have other questions or need more detailed information such as electronic files, please contact our customer service. We will be happy to provide you with one-stop service!

      This design uses a set of DASC-500 explosion-proof wet dust collectors. Due to the natural fire extinguishing property of water washing, the danger of dust explosion can be fundamentally eliminated.

Grinding dust is collected through the dust suction pipe under the sanding table. Belt conveyor and polishing dust are collected through the specially designed dust hood. Under the action of the fan, the dust is transported through the pipe to the wet dust collector. After the filtered and purified gas reaches the standard, emission. Both the sanding and dusting table and the dust cover are designed with pipeline control valves. When a certain station is not working, the control valves can be closed manually.

      Welding fume design adopts 4 welding and polishing workbenches for purification. This is a cost-effective solution designed for welding fume extraction. It is characterized by easy to use, simple operation and flexible access. Just plug in the power and start welding. The welding and polishing workbench can perform grinding operations at the same time, and has the function of exhausting welding smoke and grinding dust. The smoke and dust enters the internal filtering system of the dust collector and is discharged on the spot.

In the later period, during the use process, the customer's environmental protection after-sales department will visit back from time to time. After 3 months of use, the customer called our company to provide feedback on the use of the explosion-proof wet dust collector, activated carbon adsorption equipment, and welding and polishing workbench. The environment has been greatly improved. The workers have done more with less, and have passed smoothly EIA acceptance. In addition, economic energy saving and emission reduction save a lot of expenses.

After many years of honest management, Noda has a good reputation in the environment and continues to welcome more and more customers for itself. Noda Environmental thinks what customers want, what customers want is urgent, and we do our best! Customers are welcome to come to our company for on-site consultation and inspection, 24-hour technical telephone (same WeChat): Mr. Xue 13706116059.
