Is it Worthwhile to Recover Steam from Aerated Concrete Autoclave?

Aerated concrete autoclave (also called AAC autoclave or autoclave for AAC blocks ) is an industry pressure vessel widely used in building materials, chemical industry, medicine rubber and so on. Usually, it will use steam as working medium based on the product performance requirement. Products will be inside the AAC autoclave. Under the condition of high temperature, The aerated concrete autoclave will generate physical and chemical reaction to reach expectation requirement. There are a lot of steam when aerated concrete autoclave working.

Is it worthwhile to recover steam from aerated concrete autoclave? Recently aerated concrete manufactures have paid great attention on this.

In order to save the manufacture costs, lots of users want to recover the extra steam during the production. But is it worthwhile to recover, let us discuss.

Is it worthwhile to recover steam from AAC autoclave? The answer is absolutely YES. It will need add an specifically recover device on the aerated concrete autoclave. The aerated concrete autoclave is connected with a precuring room through the first pipeline, there will also have a pneumatic valve on the first pipe line between AAC autoclave and precuring room. It will equip one steam heater in precuring room, one side connect with the first pipeline, the other side will connect with the first steam trap.

The AAC autoclave is connected with a precuring room through the first pipeline by adopt the above technology program. The aerated concrete autoclave steam will enter into precuring room, it will need a lot of steam during the precuring process. This process can save the resource waste and recover the steam by setting up this device. There will have a pneumatic valve on the first pipe line that drive under the gas compress. The pneumatic valve have a simple structure, compressed gas will drive it. The pneumatic valve will open when the aerated concrete autoclave release the steam, it can conduction. The pneumatic valve will be closed when the aerated concrete autoclave not work. There will have a steam heater device in precuring room. It will realize the steam heat by connect with the first pipe line to rise the suitable temperature for the products. Suitable temperature will be helpful to rise the products quality. This process heats the steam discharged from the autoclave for AAC blocks, the steam itself has temperature, this can save the energy usage. The another side of steam heater will connect with the first steam trap that can drain away the steam water. This process will avoid steam loss, letting the heating process balance.

As this process shows, firstly this process will be very trouble, equipments costs will rise. Secondly, the recover steam temperature can not reach the working temperature and pressure, it will need raise the pressure and temperature again. So we suggest that no need do recover treatment for aerated concrete autoclave steam.

There is a relatively clear answer as to whether the steam in the AAC autoclave is worth recovering. If you really want recover the steam, it can realize by the above technology way of adding one recover device.

Software Introduction of Carbon Autoclave

Carbon autoclave (also called composite autoclave) system  is specially designed for composite materials production, it is very important to develop software to control completely control of the internal temperature, pressure and vacuum according to the composite material technical requirements.  The resin reaction process is the main composite material curing process, therefore, the development requirements of composite curing process include the curing of the resin properties, the thermal properties of mold, product accuracy requirement, layer design and other complex technological factors. With the addition of these technological factors, the control ability of carbon autoclave equipment is highly required.

Meanwhile, with the spread of the application range of composite materials, the output is increasing, and the cost requirements are constantly reduced, the control functions of the equipment should be optimized to control when multiple products are imported at the same time. The reasonable control method should be realized to improve the energy conservation and reduce the cost at the same time.

At present, the development of composite technology is very fast, the curing characteristics of the resin is more and more optimized, for small size, low requirements of composite components, with the promotion of “beginning pressure” resin, process simplification, the requirements for carbon autoclave control system is reduced. However, for the larger size, more complex and special functional resins and other high-end fields require a strong control function to achieve the process objectives. For mass production of composite components, curing processes are the key to control the quality stability of composite component processes to ensure that every batch production in the same curing condition to finish curing. In order to ensure the quality consistency, the automation level of the software for the control of the carbon autoclave puts forward high request, “no human intervention” realizes full automation, the same process consistency is important in the cases of the control function of requirements.

In conclusion, the main control parameters of the carbon autoclave system are  temperature, pressure and vacuum. However, in combination with the technological characteristics of composite materials, especially to realize the automation of the curing process of composite materials, the functional requirements of control software are very high, and the group of software development technicians should have a deeper understanding of the technological characteristics of composite materials and curing processes.
