Abstract:
The present invention relates to a method and a device for enclosed recycling of oil-water-sludge in an oil shale dry distillation system. According to the method, the technology is advanced, equipment investment costs are low, the occupied area is small, the failure rate is low, a highly pure shale oil product and a highly concentrated oil sludge product can be obtained efficiently, and the waste water generated in the purification and concentration processes can be recycled, thereby achieving full enclosure of the device system, greatly reducing the energy consumption, and improving the oil shale dry distillation process in the prior art.
Abstract:
The present disclosure includes systems, methods, and articles of manufacture for controlling a door. In various embodiments, exemplary systems may include a controller that may initialize and/or reset a limit count. A controller may initialize and/or reset a limit count in response to detection by a first position sensor of a first target. A controller may further initialize and/or reset a limit count by incrementing the limit count in response to a signal from a gear tooth sensor until a second position sensor detects a second target, whereupon the controller may store the limit count.
