A method for operating a bulk port device

摘要

A method for operating a system of bulk locks, which for the filling of in each case one which is under excess pressure, a process gas, such as technical apparatus containing a container or reactor are used, the locks before being filled with bulk material to be expanded to atmospheric pressure and the gas escaping in this case in one or more containers, such as pressure vessels or gasometern for further use, and is supported and the gates, in front of the emptying of their bulk content in the apparatus on the operating pressure with process gas is to be clamped, characterized in that the expansion and covering a lock comprises the steps of:a) an expansion step of the lock by pressure equalization with a process gas pressure container, whose output pressure is under the output pressure of the lock,b) one or more further depressurization steps by pressure equalization, each with a further process gas pressure container, wherein the initial pressure of the or of the further pressure vessel in each case, under the of the in step a), or of the respective previously used pressure vessel is,c) tension steps by pressure equalization with the pressure tanks are listed under b), starting with the container located on the lowest pressure and with the continued in each case on the next higher pressure container located,d) a tension step by means of pressure compensation with the pressure vessel listed under step a).
