Problems with solid feeding in reaction vessels

There are specialized feeding devices, micro-negative pressure, bell-shaped valves, and dual hoppers.

Go and study the catalyst feeder and the coal feeding mechanism for gas stoves.

Are toluene and xylene that dangerous? Is it necessary?

It is flammable, explosive, toxic, and harmful; check some information on the subject. I’m aware of one case where a toluene leak led to an explosion, and as a result the facility was destroyed.

The losses are incalculable; do you think it’s necessary?

Sodium methoxide absorbs moisture very easily, and it is difficult to pour it in manually.

I’ve never heard of the bell-type valve and the dual-hopper mentioned earlier; I’ve also not paid attention to catalysts and gasification processes. It’s difficult to ensure complete sealing with any kind of feeding device – air will inevitably get in whenever material is added

You can use the sealed vacuum feeding equipment for reaction vessels provided by Shijiazhuang Lain Machinery Technology Co., Ltd., as well as the vacuum feeding equipment for powder-based reactions and the feeding equipment for reaction vessels. These devices can be used to add 150 kilograms of sodium methoxide, 150 kilograms of urea, 750 kilograms of anhydrous sodium sulfate, and 400 kilograms of baking soda. A sealed flexible connection is used between the feeding equipment and the feeding port of the reaction vessel; an external vacuum source is utilized to create a vacuum in the reaction vessel. The materials are then transported through sealed pipes to the feeding equipment and from there into the reaction vessel. During this process, nitrogen is used for backflow to balance the internal pressure differences and to prevent oxygen from entering the reaction vessel. Reduce dust generation in the workshop, prevent organic substances from leaking out of the reaction vessels, and improve the working environment in the workshop. Regulations for the sealed transportation of materials that meet environmental protection requirements.

Materials are manually poured into the reactor through the manhole, and the organic solvents inside the reactor overflow from this manhole; the smell in the workshop is very strong； During the dumping process from the manhole, dust also escapes from it; materials spill during feeding, and the resulting messy environment fails to meet environmental protection standards. Flammable and explosive organic solvents such as toluene and xylene are prone to accidents due to static electricity; the materials fed in also need to take static electricity into consideration. You can use automatic, airtight feeding equipment for reactors; this feeding equipment is connected to the workshop’s static grounding wire, and it is linked to the reactor via airtight flexible connections. As a result, no dust is generated during feeding, which improves the efficiency of material utilization ； It prevents organic solvents in the kettle from leaking, reduces unpleasant odors in the workshop, and improves the working environment for employees there. During material feeding, nitrogen is blown back inside the equipment to reduce air from entering the reactor. The automatic sealed feeding equipment for reaction vessels has been put into use in the production of the pesticide active ingredient thiamethoxam, for the automatic and sealed feeding of oxadiazine and ultra-fine potassium carbonate into the reaction vessels.
