Enterprise for cleaning bell hoods in silicon trichloride reduction furnaces

Friend, cleaning the furnace cover is the responsibility of the technical department in the workshop. I clean them all by myself; so far, I haven’t seen anyone else doing this. Because cleaning is very simple and requires no technical skills.

Cleaning is a complex task – it’s not that simple. You need to clean everything thoroughly, bringing the interior of the furnace back to a neutral state and ensuring that the ion levels are within standard ranges. There are also many other areas that need attention, such as flanges and other similar components; there’s a lot to take into account!

Generally, it’s done internally by the company itself; I’ve never seen any specialized cleaning companies used for this purpose.

Is it being cleaned internally? It must be those companies that don’t care about the lives of their workers; a self-cleaning system costs only around ten to eighteen million, which saves time and effort as well. 6# Nancy

The cleaning equipment for the reduction furnace bell hoods of Jiangsu Shunda Company was manufactured by Beijing Yimeiide Tong Technology Development Co., Ltd. I’ll give you the phone number; go and ask at 010-80819025 by yourself

Beijing Degaojie Cleaning Equipment Co., Ltd. produces polycrystalline silicon reduction furnace bodies and bell-jar dry cleaning systems designed for the silane-based polycrystalline silicon production process; these systems are used for clean, pollution-free dry cleaning under conditions where the adhesion of silicon contaminants in the reactors of the reduction workshop is low. During cleaning, an up-and-down moving and rotating mechanism is used to drive high-pressure gas spraying, while a special rotating brush assembly is employed to spray and clean the surface of the reactor up close, thereby achieving cleaning. The requirements of various operating conditions can be met by cleaning the rotary speed control mechanism. During cleaning, a special dust removal and purification device is used to remove dust and purify the air in one go. II. System Features 1. The device features a mobile unit structure ； 2. The purified air can achieve a cleanliness level of 100,000, and can be released entirely indoors ； 3. A fully enclosed, dry cleaning method is used to ensure no secondary pollution to the environment ； 4. The electrical design complies with all the requirements regarding explosion protection, and the equipment is equipped with static electricity discharge devices ； 5. The control mode can be fully automatic or manual ； 6. Low total operating power and low noise. Schematic diagram of the cleaning device for the base of the polysilicon reduction furnace. III. Cleaning process: The reaction vessel is lifted onto the cleaning platform → positioned → connected → the purifier is started → rotation is initiated → the up-and-down moving mechanism is activated → high-pressure gas is blown along the walls → a rotating brush moves upward and downward to clean the surface → the area is purged with clean gas → the reaction vessel is lifted again → inspection is performed. IV. Equipment Composition It mainly consists of a cleaning platform, gas injection devices, dust collection and conveying pipelines, control valves, power mechanisms, cleaning mechanisms, quick connectors for various pipelines, dust removal and purification units, and an electrical control system. The main components are made of imported parts, ensuring reliable and stable operation as well as a long service life. Operation and maintenance are simple. One of the earliest companies in China to engage in the research, development, and production of equipment for cleaning reduction furnaces, with numerous successful projects to its credit.
