Title: Electrostatic type air purifier
Inventor: KAYAMA MASAAKI
IPC: B03C3/14
Filed: 1986-06-20
Abstract: PURPOSE:To enhance dust collection efficiency by an inexpensive structure, by forming a dust collection part from two corrugated plates of a main filter and an earth electrode and allowing charged dust to flow in triangular parts formed of crests and troughs of the corrugations of the main filter to generate a vortex stream. CONSTITUTION:When dust-containing air is sucked from a suction port 26 to remove coarse dust by a pre-filter 32 and subsequently reaches the space between an ionizing electrode 21 and an opposed electrode 22, fine dust is charged by an ion current. This charged dust flows in a charged main filter 28 and receives electrostatic force by a local electric field to be adhered to and collected by the surface of fibers. As a result, high voltage is applied between the surface of the charged main filter 28 on the side of the ionizing electrode and the earth electrode 29 of a rear part to form a high electric field. Further, this inflow air impinges against the crests of the corrugations of the charged main filter 28 and comes to a vortex stream at triangular parts consisting of crests and troughs and the growing of dust and the increase in diffused charge are achieved.

Abstract: PURPOSE:To accomplish a stable control of liquid level of an evaporator checking variations in the liquid flowrate at the inlet thereof during the quick load cutting operation by determining a set value of the liquid level thereof for an LPG gas supply plant in thermal generation plants based on the load of the evaporator. CONSTITUTION:A function generator 211 calculates a set value of an LPG liquid level LEVR of an evaporated based on LPG vapor flowrate Fcv3 at the outlet of the evaporator and a deviation LEVE is determined between this value and an LPG liquid level LEV with a subtractor 212. Then, a proportional integrator 213 calculates a signal Fcv1RM for correcting the set value of flowrate at the inlet of the evaporator to which the vapor flowrate Fcv3 is added with an adder 214 to calculate a demand signal Fcv1D for LPG flowrate at the inlet. A subtractor 215 determines a deviation between the demand signal and the liquid flowrate Fcv1 at the inlet to control a regulation valve CV1. This enables stable control of the liquid level during the quick load cutting operation.

Abstract: PROBLEM TO BE SOLVED: To detect not only a break of a signal line, but also a short circuit between signal lines by detecting a defective contact of signal lines by using two kinds of inspection data on a current conduction state and a current non- conduction state about the signal lines. SOLUTION: A comparing circuit 17, to which comparison data are inputted from a comparison data output circuit 16, compares the inspection data obtained from respective signal lines 21 to 28 with the comparison data and outputs a discrepancy detection signal (c) when detecting a discrepancy. A comparison data output control circuit 19 outputs an error registration permission signal (d) to a register 18 where an error has been registered in 5 millseconds after the comparison data output circuit 16 was instructed to output inspection data and the error registration register 18 registers and holds the error when the data discrepancy detection signal (c) is outputted. Thus the error is registered in the error registration register 18 and then it is known that some of the signal lines 21 to 28 connected through a connector 20 have a break or a short circuit.
