Tips to Run Reactors

To ensure uniform and rapid response can be carried out to improve efficiency, usually in the reactor is equipped with the appropriate mixing device, so they bringdynamic shaft seal and prevent leaks.

Reactor mostly clearance operations, sometimes in order to ensure product quality,after each batch of material are required to clean; kettle equipped with a quickopening manhole top and hand-hole, Shenzhen, network optimization, ease ofsampling, the measured volume to observe the reactions and to enter internalinspection devices.

Automated and continuous production of the gap instead of heavy manualoperations, such as the use of process control, can guarantee stable production,improve product quality, increase revenue, reduce manual labor, but also to eliminatepollution of the environment. Therefore, the resistance wire and the reactor body is not the space formed between the gap.

Selection Pressure Vessel Safety Valve

The selection pressure vessel safety valve should be consistent with the following eight principles:
1, the pressure vessel safety valve should be considered the choice of process conditions and container properties of the working medium, heavy volume leakagefrom the container security, physical and chemical media, working pressure range ofsecurity features and other considerations.
2, the safety valve must not be less than it is to send the heavy volume of safety ventheavy volume.
3, for the low working pressure, high temperature nor the pressure vessel can be used vibration lever safety valve.
4, from a closed structure, pressure vessels for high pressure, large containers anda large security leaks in heavy volume, the best choice of all the container from thelow-pressure safety valve, for the smooth operation of the absolute pressurecontainer safety valve should be selected from the micro.
5, for the costumes of toxic, flammable, or pollution of the environment of the mediashould be used in a closed pressure vessel safety valve.
6, the choice of reactor safety valve, the pressure must also consider the scope ofwork.

Details Characters of Large-capacity Reactor

Large-capacity reactor has the following characteristics:

Throughput - high-capacity single-vessel wall reactor to replace the traditional jacketed vessel wall, the reaction vessel does not bear or bear only a small external pressure, and thus get rid of the traditional external pressure vessels as volume increases with to the vessel wall is too thick, heat transfer and other adverse factors, making the volume of reactor volume up to 30m 3, and even more, which greatly increased the production capacity of a single reactor.

High heat transfer coefficient - the heating and cooling the reaction medium are used built-in plate heat exchangers, heat transfer coefficient than the traditional coil heat exchanger is 40%, and the plate heat exchanger structure is more compact, more conducive to the volume The layout of the reactor large enough area of ​​heating and cooling, the resin synthesis process of a more uniform and stable.

Easy to maintain - as built-in plate heat exchanger is removable, so easy to clean and repair, helps to reduce operating failures, improve production stability.

Temperature Problem of Heat Exchanger

Heat exchanger in the relative flow of fluid downstream and upstream are generally two. Downstream, the maximum temperature difference between the two fluids at the entrance and along the heat transfer surface, gradually reducing to a minimum temperature at the exit. Reflux, the two fluids along the heat transfer surface temperature distribution is uniform. In the cold and hot fluid inlet and outlet temperature under certain conditions, when the two fluids are no phase change, the maximum temperature difference in the average upstream downstream minimum.

Upon completion of the same heat transfer (Heat exchanger)conditions, using counter-current can increase the average temperature difference, heat exchanger heat transfer area is reduced; if the heat transfer area of ​​the same, using reflux heating or cooling fluid can reduce consumption. The former can save equipment costs, which can save operating costs, it is used in the design or production should maximize the use of the countercurrent heat exchanger.

When the production process conditions and production requirements change, the plate heat exchanger plates as long as the increase or decrease the quantity or change the channel plate assembly process the form, you can meet the requirements. Plate heat exchanger metal consumption is low. Plate heat exchanger made of stainless steel or titanium to suppress the main heat transfer, sealing pads, clamping bolts and pressure plate frames and other parts of the whole composition.

1) conditions are harsh. Pressure vessels of different sizes will not only bear the pressure of the load (in general, or pulsating load) and other loads, and some still in high temperature or cryogenic operating conditions, the working medium is oftencorrosive, relatively harsh environmental conditions .

2) pressure vessel - easy to overload. Pressure inside the container is often due to operational errorsor abnormal reaction increased rapidly, and often not found in the case of rupture ofthe container already.

3) pressure vessel - the local stress is more complex. For example, around openings in the containerand other structural discontinuities, often due to high local stress and repeatedloading and unloading caused by fatigue cracking.

4) pressure vessel - often hide serious defects. Welding or forging containers, often left behind in the manufacture of small cracks and other serious defects, which, if expanded in the operation of, or in appropriate conditions (such as temperature, nature of the working medium, etc.) will cause a sudden rupture of the container.
