摘要： PROBLEM TO BE SOLVED: To confirm a safe state by a gas composition-concentration detecting means provided at a supply gas piping system in purging upon detecting leakage gas in a storage body. SOLUTION: A gas composition-concentration meter 26 is provided at an intermediate part of a lead-out pipe 23 of a supply gas piping system 21 connected to a main plug 20 of a special gas cylinder 2 for silane, phosphine, or the like stored in a storage body 1. When the leakage of special gas in the storage body 1 is detected by a leakage gas detector 47 or 48, the supply of special gas is cut off, and inert gas such as nitrogen gas is fed from a purging gas cylinder 3 so as to purge special gas in the piping and to discharge gas in the storage body 1. At this time, the composition and concentration of gas in the supply gas piping system 21 are detected by the gas composition- concentration meter 26 so as to confirm substitution with inert gas in the piping. Whether or not the purge of the piping system is positively performed can thereby be confirmed so as to source safety in inspection and restoration work.

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 maintain a catalytic efficiency at a high level by maintaining a sulfate group of a catalyst by adding SO2 to denitrifying catalyst. CONSTITUTION:A sampling probe 1 is formed of a double tube, an NOx line 6 is provided between an outer pipe 4 and an inner pipe 5, an NH3 line 7 is formed at the pipe 5, a denitrifying catalyst 8 is provided in the pipe 8 to denitrify sample gas in which the NH3 is equivalently reacted with NO. The catalyst 8 is slightly lowered in its activity by coating a base material of TiO2 formed in a honeycomb state with WO3, and sequentially supplied with SO2 from an SO2 gas cylinder 11 through a pipe 10, thereby maintaining a sulfate group. Thus, even if it is used for a long period, its catalytic efficiency can be maintained at a high level.

摘要： PURPOSE:To prevent reading errors and to facilitate the processing and control of data by inputting computed analog signals and A/D-converted digital signals into a recorder, and imparting the recording function of waveforms and characters to the recorder. CONSTITUTION:Analog signals as measured data from an analyzer 1 are amplified in an amplifier 2. A part of the signals is amplified in an integrator 3 for a specified time. The signals are inputted into a recorder 4, and the waveforms are recorded. The remaining part becomes the digital signals in an A/D converter 5. The signals are operated in a microcomputer 6, and the characters are printed on the recorder 4 through a communication interface 8. At this time, a clock device 7 sends out a preset time-base signal into the computer 6. The recorder 4 has the functions for the waveform recording for the analog signals and the character printing of the digital signals. Therefore, the data can be found in real time. Thus, reading errors can be prevented, and the processing and control of the data can be readily performed.

摘要： PURPOSE:To take an accurate, simultaneous, and continuous analysis of the concentration of non-methane HC directly by using only one HC detector. CONSTITUTION:A sample liquid S is diverted to two flow passages and liquids in both flow passages are modulated at mutually different frequencies F1 and F2 by using liquid modulating means V1 and V2 and supplied to an analytic part A with only one HC detector D continuously at the same time. Specially, a sample liquid S1 from which non-methane HC in the liquid S is removed by a converter C in one flow passage is modulated at the frequency F1 by using a zero liquid R0 as a comparison liquid, and a liquid S0 in the other flow passage is modulated at the frequency F2 by using the liquid S1 as a comparison liquid. Thus, only one detector D is only provided to the analytic part A to measure the concentration of methane and the concentration of the non-methane HC individually and directly.

摘要： PURPOSE:To enable highly accurate measurement to be conducted even if using a rather simple dilutor by obtaining a multiple of calibration gas concentration against analyzer output of the calibration gas. CONSTITUTION:For instance, sample gas SG containing each 30ppm of an SO2 and an H2S, and dilution gas DG are introduced into a dilutor 1 of which diluting rate is 1/98.5, and consequently the SG being diluted to 1/98.5 is introduced into a converter 3. The H2S in the SG is oxidized and converted into an SO2 and therefore a total concentration of the SO2 increases to 60ppm. However, because of the dilution, actual concentration becomes to be 60/98.5=0.609ppm and therefore output signal a of an SO2 analyzer 4 which full scale range is 1ppm, indicates 0.609ppm. On the other hand, output signal K of the analyzer 4 for calibration gas KG of which concentration is 80ppm, in case of calibration thereof, is 80/98.5=0.812ppm, and a calculation control part 5 multiplied the signal K by 80/0.812 98.5, in order to adjust the value to 80ppm. Accordingly, since the value is multiplied by 98.5 even in the case of SG measurement, the value of 0.609ppm finally becomes 60ppm and then the control part 5 outputs the very value as concentration signal b.

摘要： PURPOSE:To continuously measure low and high concn. components to be measured with good accuracy using only one detector, by respectively supplying sample gases containing low and high concn. components to be measured while modulating both of them at mutually different frequencies using comparing gases. CONSTITUTION:Fluid modulation means 4, 5 respectively modulate a sample gas SL containing a low concn. component to be measured and a sample gas SH containing a high concn. component to be measured at mutually different frequencies using comparing gases R and both gases are simultaneously and continuously supplied to only one detector at a constant cycle so that the flow rate of the sample gas SL is more than that of the sample gas SH. The output signal from the detector 1 is separated into the signal components of respective modulation frequencies to the sample gases SL, SH and both components are rectified and smoothed to make it possible to simultaneously measure the concns. of the low and high concn. components to be measured.

摘要： PURPOSE:To lower measuring errors due to a noise component accurately and easily, by setting a ratio between modulation frequencies of two fluid modulation means so as to be an even number or one-eventh. CONSTITUTION:Sample fluids S1 and S2 are modulated with frequencies F1 and F2 different from each other by comparison fluids R1 and R2 using fluid modulation means V1 and V2. The sample fluids S1 and S2 (R1 and R2) modulated are supplied to an analyzer section A having a detector D simultaneously and continuously. The modulation means V1 and V2 are so set that a ratio of the modulation frequencies F1 and F2 is an even number or one-eventh. An output signal O from the detector D is separated into signal components O1 and O2 with the modulation frequencies F1 and F2 with respect to the sample fluids S1 and S2 using a signal processing means B comprising a frequency separation circuit and a signal rectifying circuit and undergoes a rectification processing thereby obtaining an analysis value pertaining to the sample fluids S1 and S2.
