摘要： PROBLEM TO BE SOLVED: To provide a sludge drying device capable of maintaining a predetermined drying treatment condition even when the exhausting condition of a drying machine is worsened. SOLUTION: A temperature detector 14 for detecting the temperature of gas or vapor in a centrifugal thin film drying machine 2 is provided on the inner periphery of upper part of the inflow port of carrier air supplied to the centrifugal thin film drying machine. A measured value TM, detected by the temperature detector 14, is inputted into a control device 7 to compare the same with the allowable value of temperature, which is preset in the control device 7, and when the measured value TM is higher, an exhaust gas fan set value FS is inputted into an inverter 13 to increase the number of rotations of an exhaust fan 4.

摘要： PROBLEM TO BE SOLVED: To drastically reduce sludge powder by providing a cutout for hitting the sludge powder into a heat transfer drum by centrifugal force at one portion of an evaporation steam delivery port. SOLUTION: Raw sludge 6 that is supplied from a sludge throw port 1a into a heat transfer drum 1 is dispersed so that it is along the inner wall of a heat transfer drum 1 by a distribution ring 3 that is rotated along with a spindle 2. Further, the raw sludge 6 is extended in a thin-film shape while being pressed against the inner wall of the heat transfer pipe 1 by a blade 4. Then, the raw sludge 6 gradually falls due to dead weight and pressure. In that case, the raw sludge 6 is heated by heated steam that is supplied into a steam jacket 5 of the fresh air of the heat transfer drum 1, and the water is evaporated for drying to become dry sludge 8. On the other hand, water that is evaporated from the raw sludge 6 is unloaded from an evaporation steam exhaust port 9. At this time, the sludge powder hits against a cut-out of an end part in the rotary direction of the evaporation steam exhaust port 9, thus drastically reducing the exhaust of the sludge powder from the evaporation steam exhaust port 9 to the outside.

摘要： PROBLEM TO BE SOLVED: To efficiently separate solid matter from a malodorous gas generated inside the heat transfer drum of a centrifugal thin film dryer. SOLUTION: In this system, a malodorous gas generated inside the heat transfer drum 1a of a centrifugal thin film dryer 1 is transferred to a deodorization device 21 through malodorous gas lines 25 and 26 and a scrubber 19. The malodorous gas lines 25 and 26 have U-shaped parts such as part 25a, respectively. In the U-shaped part 25a, etc., solid matter in the malodorous gas can be separated. The solid matter separated in each of the U-shaped part 25a, etc., is withdrawn from the corresponding one of withdrawal ports 27 and falls.

摘要： PROBLEM TO BE SOLVED: To operate a generator motor continuously at allowable vibration level by sustaining the rotational speed of generator motor as it is when the vibration deviates from an allowable level and then increasing (decreasing) the rotational speed abruptly to an allowable high (low) rotational speed upon elapsing a predetermined time. SOLUTION: A controller 9 receives the rotational speed of a generator motor from a rotational speed detector 10 and the detection signal from a vibration sensor 12 for detecting the vibration of floor 8 of a control board 11 amplified through a vibrometer 13. The controller 9 delivers a control signal to a cycloconverter 5 and a guide vane 14 and controls the rotational speed and exciting current of generator motor such that the vibration of floor 8 of control board 11 is settled within an allowable value. When the vibration deviates from a predetermined allowable value, rotational speed of generator motor at that moment of time is sustained as it is and then the rotational speed is increased (decreased) abruptly to an allowable high (low) rotational speed upon elapsing a predetermined time.

摘要： PURPOSE: To reduce the axial vibration even if the ununiform thickness distribution of a deposited material is caused in the circumferential direction with solid-liquid separating treatment by providing plural drill hole-shaped clarified liquid outlet holes equally spaced on a circumference with a concentric diameter a little larger than the inside diameter of the upper end plate. CONSTITUTION: When a separation drum 22 is rotated at prescribed speed of rotation by a motor driving device 29 and a liquid to be treated is fed into the separation drum 22 from a liquid feeding nozzle 32, the liquid to be treated is held on the inner surface of the separation drum 22 by centrifugal force. At this time, solid content which has received centrifugal force and has large specific gravity is subjected to sedimentation on the peripheral wall surface of the separation drum 22 and is settled to be turned into cake 40. Clarified liquid 38 from which solid content has been removed overflows clarified liquid outlet holes 39 installed on an upper end plate 23 and is discharged from an outlet nozzle 33. Since at least four or more clarified liquid outlet holes 39 in the shape of a cylinder equally spaced on a circumference with a concentric diameter along the inside diameter side are made in the upper end plate 23, phenomenon of the clarified liquid 19 deflecting in one direction is prevented.
