How to handle the malfunction of stainless steel reactor

Stainless steel reactor vessels may generate static electricity due to different operating conditions during operation, so how should we prevent static electricity. First, consider installing an electrostatic moderator. Install an electrostatic moderator at the position after the filter in the high melting kettle and before the fluid enters the storage tank. Prevent water and Autoclave media from being mixed and transported together, prevent different media from being mixed and transported together, and prevent liquid media, oil and gas and compressed air from being transported together. The storage tank should be dehydrated even if it is dehydrated. Pay attention to dehydration before feeding. Manipulate the medium injection method. Media should be injected from the bottom of the storage tank to prevent it from being injected from the top as much as possible. Jumping. The floating roof of a floating roof tank should be bridged with the tank wall. When insulation materials or corrosion are used between pipelines, valves, flow meters, filters, pumps, and tanks, it is necessary to cross connect them. Control the medium flow rate. The higher the flow rate, the easier it is for static electricity to occur. In addition, anti-static additives can also be added in the Autoclave to prevent the static charge in the medium from accumulating and quickly leak to the ground through the jumper load grounding.

Reason: It is to prevent swirling phenomenon.

Function: When the viscosity of the material is low, the mixing paddle rotates at high speed and undergoes a tangential flow under the action of centrifugal force, which can cause the liquid to be thrown around the kettle wall and rise along the circumference of the kettle. The central liquid level naturally drops, forming a large cavity in the stainless steel reaction kettle. This phenomenon is called swirling. The swirling material will rotate closely with the mixing shaft and cannot achieve good mixing. If there are multiphase materials in the mixing, there is a possibility of phase separation or stratification. When the viscosity of the material is high, a lot of air will be sucked in on the surface of the liquid layer, reducing the apparent density of the liquid and causing the mixing shaft to vibrate under different forces of magnitude.

Chemical reactions require constant temperature, and the reaction process is often accompanied by the occurrence of thermal effects (exothermic or absorption). Therefore, most stainless steel reactors are equipped with heat transfer devices to meet the requirements of heating or cooling.

The selection of heat transfer structure and heat carrier mainly depends on the required operating temperature, reaction heat, heat transfer rate, and process requirements. The heat transfer of a stainless steel reaction kettle is crucial for achieving good reaction conditions. Poor heat transfer can affect the reaction. So the heat transfer operation of the reactor is important for maintaining the smooth progress of the chemical reaction.

The commonly used heat transfer methods for stainless steel reactors are jacket and coil heat transfer. On the outer side of the kettle, jackets of different shapes are installed by welding or flange connection to form a closed space with the outer surface of the kettle. In this space, a heat carrying fluid is introduced to heat or cool the material and maintain its temperature. This structure is called a jacket.
