30KW Central Dust Collection Project for Welding Rooms In Factory

In June 2021, the initial acceptance of the 30KW central Welding Fume Exhaust System project undertaken by Jinan Moland Environmental Tech. Co., Ltd. ("Moland") passed smoothly. The project is for the fume extraction of customer`s robotic welding working conditions.

The main equipment is composed of 30kw Industrial Dust Collectors; a wind box; a electric control cabinet, which is designed independently to installed indoor, to facilitate the operation of the Dust Collector and monitoring the operating status; fume control suction hoods, and a rainproof shed, which is designed and built above the equipment to prevent the dust collector from rain.

The welding fumes will be controlled in the suction hoods and sucked into the dust collector`s filtration system via ducts. The filtered air will be released into the atmosphere from a 15-meter chimney in an organized manner. There is a detection port above 1 meter at the connection between the dust collector and the chimney. The detection platform and detection ladder are beside the chimney to facilitate real-time monitoring of emission indicators.

This project has 8 welding rooms, containing 6 robotic welding rooms with 5 rooms size L4.9*W3.15*H3m and 1 room L4.9*W3.75*H3m; 2 robotic welding rooms with two robots each and room size is L5.8*W3.8*H3m.

At the center of the welding platform, a soft rubber curtain is installed to block the arc. The rubber curtain hangs from a height of 2 meters from the ground. The bottom of the rubber curtain is cut according to the shape of the platform. The distance between the bottom or the ground gap is not more than 10mm. Staggered stacking installation, the length of the stacking area between two rubber curtains is not less than 30mm to form a relatively closed space, so welding fumes will not overflow.

Partition walls are installed between the loading areas of each welding room. The waistline of the partition wall is 1 meter high. Purification board material is used below the waistline, and metal frames and translucent light-blocking materials are used above the waistline. The feeding area of each welding room has an independent space, and the appearance is uniform and tidy.

The control cabinet adopts frequency conversion PLC control, built-in various reminder settings, smarter and more human-friendly.

Power status monitoring: faulty phase, overvoltage and undervoltage alarm, overload protection to prevent damage to the motor and electrical components.

Air pressure status monitoring: The air source pressure is too low to alarm to prevent incomplete dust cleaning, the pressure difference meter intuitively displays the status of the filter element, and the pressure difference is too high, automatically pulse rotor blowback.

Operating temperature monitoring: The system will alarm when the temperature is too high to prevent fire.

Ash hopper status monitoring: The system senses the ash hopper's locking state with automatic ash hopper lifting function to ensure that the ash hopper is in place, improve the tightness of the ash hopper and ensure the dust collection effect.

Realize the function of scheduled blowback and off-line blowback.

Set reminders for the use and replacement time of consumables.

Due to the customer`s on-site production requirements, the welding room is often used at different times, so we install a manually operated valve on each smoking port; open/close according to the usage at any time, and the frequency converter will automatically adjust the frequency according to the number of smoking ports to achieve energy saving The role of emission reduction

Moland insists on taking customers as God and takes every need of different customers seriously. Details determine success or failure, professionalism highlights value!
