Installation of 20,000L reactor
Thread Content
I am currently designing a new workshop with a reinforced concrete structure. The largest reactor has a volume of 20 cubic meters. Can such a large reactor still be lifted using lugs and brackets on the beams, just as usual? I wonder if anyone has installed 20,000-liter enamel reactors – how do you handle them? Another point concerns the selection of the condenser for the reactor. Since this is our first time using a reactor of such a large size, the largest reactors we have used before were 8000L in capacity, with condensers covering an area of 12 square meters. So, for a 20000L reactor, should the area of the condenser be increased proportionally based on the heat exchange area of its jacket?
It can be lifted. The heat exchange area of the condenser is determined through calculation for practical applications, and it cannot be designed simply by scaling up. It still needs to be calculated.
Here’s the thing: some of our experienced workers are concerned that, using the usual lifting methods, the torque on the small beams surrounding the reactor vessel could be very high, and they might not be able to withstand it； Some people have also said that they have seen 20,000L reaction vessels installed in other locations by adding legs to the bottom of the vessel and then welding it to a steel platform or a concrete platform. Since many people have not encountered this situation, I would like to ask for everyone’s advice!
The total weight and the method of support, as well as the location of the supports, are provided; the civil engineer then calculates whether the strength of the structure is sufficient to meet the requirements, thereby determining whether lifting is possible.
When designing a new workshop, for large-scale equipment, the professionals in charge of equipment layout should suggest to the structural engineering team the installation and transportation routes or methods for lifting the equipment. Based on these suggestions, the structural engineering team will take into account the load exerted by the equipment when determining the installation, transportation routes, lifting routes, and lifting points. When designing the small beams used for supporting the cow legs, it is necessary to take into account the lifting loads of the reactor. The area of the condenser – I’ve already answered that for you on the 2nd floor. For your reference.

For 20,000L enamel reactors, lug-mounted support can be used; it is best to place them on a concrete foundation. This way, the vibrations generated during operation of the reactor are reduced, which helps prevent damage to the enamel on the reactor’s connections due to vibration. As for the strength of the supporting beams, as mentioned earlier, it must be calculated by engineers from the civil engineering department, and construction can only proceed once the required strength is achieved. Our company originally used steel platforms to support large enamel equipment, but the connections to this equipment kept getting damaged, so we carried out technical modifications and switched to a concrete structure. Additionally, by installing buffer rings between the connections and the equipment, this problem was resolved； For condensers, calculations are required; for example, a 8000L reactor requires a condenser with an area of 12 square meters. It is necessary to consider the change in the diameter of the gas pipes between a 20000L reactor and an 8000L reactor, that is, the change in gas flow rate. Of course, after such a simple scaling up, the condenser still needs to be adjusted accordingly – it should have a sufficient heat exchange area; too small an area will not work.
We are using models with capacities of 20,000, 15,000, and 30,000. We use skirt supports; what about condensers? Of course, it needs to be calculated; it can’t just be enlarged. For your reference, our unit with a capacity of 20,000 has a condenser of around 40 cubic feet. :lol :lol :lol
The 12,500-liter tank is installed directly on the beams and welded in place. The 20 cubic meter stainless steel tank has legs that support it on the ground; no special concerns arise when considering operational factors… Of course, the beams in our workshop are designed with dimensions of 900*400. The main rebar consists of 3*25 + 2*25 + 3*25 strands, while the secondary rebar consists of strips 400 mm wide; the strength calculations show no issues. As for the other tank, the 15,000-liter one, lifting lugs are installed on it. Since the rotation speed isn’t very high, at 40 revolutions per minute, there’s no problem. The 6,000-liter tank, with a rotation speed of 100 revolutions per minute, has reinforced embedded elements installed in it and is also welded in place.
Using a skirt seat really is reassuring. Haha.
