DrM can supply stand-alone candle filters or complete, skidded turnkey packages. All of our filters are custom-designed to meet the needs of each application. Unique Options are available above the minimum supply scope to optimize performance, operation efficiencies and flexibility. The following is a description of some of these Options:
Specialized filtrate piping: DrM can supply headers which group multiple filtrate outlet nozzles into one single one, a manifold which collects the filtrate from the registers and can act as a buffer for the compressed gas required for blow-back, as well as a register by-pass with associated valves to be used when register-wide drying is implemented.
Pressure Reducing Valve: For proper operation, the FUNDABAC® candle Filter normally requires gas supplied at three pressure levels. In order to simplify the process and improve the functionality of the system, DrM recommends the Option of a single Pressure Regulating Valve (PRV) piloted by an I/P transducer. Compared with conventional solutions such as control valves controlled by a pressure transmitter, the PRV allows a much faster response and more accurate pressure regulation, preventing risks of cloth damages due to excessively high gas pressure or of inefficient cloth cleaning due to insufficient gas pressure.
Process Engineering and Control System Packages: DrM can support the activities of very large plants as well as small ones with customized Process Engineering and Control System packages. These packages include:
• Process Control Philosophy and Process Description: Narrative description of all phases, interlocks and alarms, safety conditions, set points and instruments ranges, etc.
Furthermore, DrM has developed a self-explanatory PLC software which does not require any programming knowhow. The user can control the process and modify the cycle configuration (add/remove process steps, modify timers and set points) from the HMI with no external assistance. A control panel with programmed PLC is the ideal filter add-on to avoid any process control issue.
Discharge Valve: Among the most critical components for the successful operation of a FUNDABAC® Candle Filter is a discharge valve that ensures both a problem-free cake discharge as well as a tight shut-off under pressure when closed. A wide range of disc and valve seat materials of construction is available. The candle element placement and the presence of the heel drain pipe are other factors that make both the selection and the installation of a discharge valve a critical step in a successful system design. Bottom discharge valves are typically required to be within the scope of DrM’s supply.
