摘要： PROBLEM TO BE SOLVED: To discharge waste liquid being equal to below prescribed reference to a drain by providing a water quality measuring part which quantitatively detect the chemical or physical quality of waste liquid in a draining path and monitoring the chemical or physical quality of waste liquid. SOLUTION: Waste liquid is permitted to flow inside a sink 2, into a conduit pipe by way of a draining port 3 and to a trap 4. The pH and the electric conductivity of the waste liquid are measured by a pH sensor and an electric conductivity sensor of a water quality measuring part 10 which is provided in a trap part 4. The detection outputs of the sensors are transmitted to a monitoring box 21, a pH value and the electric conductivity are obtained and displayed in a display part and it is judged whether or not the measured values are equal to below a reference value. When both pH and the electric conductivity obtained by measurement are equal to below the reference value, flowing of waste liquid against the sink 2 is continued. The measurement values concerning waste liquid at this time are recorded in the memory part of the monitoring box 21 together with a data and other required matters.

摘要： PROBLEM TO BE SOLVED: To reduce effect of interference of CH4 as interfering component of an HCl detector using a non-dispersion infrared absorption(NDIR) method used in a garbage incineration plant or the like by subtracting a CH4 value converted from a CO value detected by a CO detector from a HCl value detected by the HCl detector. SOLUTION: This HCl detector 1 for a garbage incineration plant is constituted of a NDIR type HCl detector 10 and an NDIR type CO detector 11 which have light sources 2 and 3, coppers 4 and 5, measuring calls 6 and 7 and optical filters 8 and 9, respectively. An exhaust gas discharged from an incineration boiler is introduced into measuring cells 6 and 7 to detect an HCl component with the HCl detector 10 and a CO component with the CO detector 11. Detection outputs are separately amplified by amplifiers 12 and 13 and a conversion value of CH4 determined from a CO component value is subtracted from an HCl component value by a subtracter 14, thus enabling the determination of the HCl value corrected by interference.

摘要： PROBLEM TO BE SOLVED: To obtain an infrared gas analyzer in which the temperature of an infrared detector as a whole is adjusted in a well-balanced manner and in which a temperature abnormality and a failure are reduced by a method wherein a facelike heater which is provided with a self-temperature control function is arranged at the detector. SOLUTION: An infrared gas analyzer is provided with an infrared light source 1, with a filter part 2 in which a semitransparent mirror used to pass infrared rays in a usage wavelength region, a BPF and the like are housed at the inside, with a sample cell 3 which circulates a sample gas, with an infrared detector 4 which analyzes a component in the sample gas and with a facelike heater 5 Which is pasted on the rear surface of the infrared detector 4. As the heater 5, a thin sheetlike heating element, e.g. a heating element whose thin sheet itself is composed of a polymer conductive material, can be used, and its shape and its calorific value can be designated freely. In addition, the heater 5 is provided with a self-temperature control function due to the characteristic of the conductive material itself or due to a combination with a thermostat, and the circumference of the infrared detector 4 can be maintained easily at a constant temperature. Consequently, its temperature can be adjusted in a well-balanced manner as a whole.

摘要： PURPOSE: To adjust classification characteristics variably by installing more than one blade which can adjust an angle in the lower part of an inner cylinder installed to discharge purified gas outside with an opening in the lower part faced the upper part of a separation chamber. CONSTITUTION: In a variable classification type cyclone equipped with a gas intake 1 for introducing exhaust gas and an inner cylinder 6 for discharging purified gas, more than one blade 7 which can adjust an angle is installed in the lower part of the inner cylinder 6. The blades 7 are connected interlockingly with each other by a link member and can change an angle by an actuator 9 such as a solenoid to be able to adjust classification characteristics changeably. In this way, when a revolving current collides against the blades 7, coarse particles loses inertia force and falls downward to be stored in a dust banker 4, while only fine particles are discharged from the inner cylinder 6 to be collected by a filter 11. In this process, a controller 8 computes a pressure loss on the basis of the signal of a pressure detection means 12 and controls the actuator 9 to minimize the pressure loss.

摘要： PURPOSE: To simultaneously detect two or more components, and judge whether or not measuring object gas is introduced to a single sample cell by arranging a light source on one side by sandwiching the cell, and arranging a light dividing means on the other side. CONSTITUTION: A light source 2 is arranged on one side by sandwiching a cell 1, and a chamber 4 enclosing a half mirror 3 is arranged on the other side, and a measuring solid detector 5 is arranged on one optical path A side of the half mirror 3, and a gas filter 6 and a comparing solid detector 7 are arranged on the other optical path B side, respectively. The change in the quantity of light to a measuring component absorbed by the cell 1 is equally divided to the detectors 5 and 7 by the half mirror 3, and respective detecting signals are outputted. The ratio or the difference of a signal quantity changes when the same kind of gas with sealing gas of the gas filter 6 is introduced to the cell 1 and when a different kind of gas is introduced to the cell 1. Therefore, whether the gas introduced to the cell 1 is measuring object gas or not can be judged by the ratio or the difference of this signal quantity.
