摘要： PURPOSE:To prevent the overload of a brine discharge pump at the start time of operation, in the titled water making apparatus provided with a final stage brine level regulator, by determining the set value of the aforementioned regulator by using the signal of a separate high temp. stage brine level detector. CONSTITUTION:In a multi-stage flash evaporation apparatus consisting of plural stages of evaporation chambers 4 each having a weir 15 vertically provided to the bottom plate thereof, a final stage brine level is detected by a detection meter 27 and made equal to a set value on the basis of the detection signal by a final stage brine level regulator 41. Herein, a brine level meter 50, a constant signal generator 51, an adder 52 and a level set value correction and operation apparatus 100 are additionally provided. The apparatus 100 gradually increases output (the input of the adder 52) corresponding to the reduction in the output of the first stage level meter 50 (capable of being substituted by second and third stage ones) at a start time and imparts the same to the adder 52. On the other hand, the generator 51 outputs the final stage level set value at the time of steady operation to apply the same to the adder 52. The adder 52 applies said output to the regulator 41 as the final stage brine level set value.

摘要： PURPOSE:To obtain constant pH-response regardless of desulfurization load, by altering the proportional sensitivity of a pH controller as functions of desulfurization load and a pH set value. CONSTITUTION:The desulfurization load signal, which is obtained by multiplying the signals from an SO2-concn. detector 1 and an exhaust gas flow amount detector 12, and the pH set value signal from a first function operator 14 are inputted to a second function operator 21 to operate and output the proportional sensitivity K of a pH controller 22. The pH controller 22 employs the output of the second function operator 21 as proportional sensitivity and P, PI or PID control is performed from the pH detection signal of a recirculated solution and the pH set value signal to control the supply flow amount of an adsorbent. Because the proportional sensitivity K is altered in proportion to the CaCO3-concn. in a tank and the supply flow amount of the adsorbent is controlled corresponding to the CaCO3-concn. in the tank and constant pH response is obtained over an entire load range.

摘要： PURPOSE:To make pH response characteristics substantially constant over the entire desulfurization load range and to stabilize SO2 concentration in a gas being treated, by a method wherein the proportional sensitivity of a pH adjustor can be varied in relation with desulfurization load. CONSTITUTION:The flow rate and the SO2 concentration of the gas being treated are detected by detectors 10, 9, are input into a multiplier 11, and a desulfurization load signal S11 by a constant on the basis of the relationship between the desulfurization load and the flow rate of an absorbing agent supplied, and outputs a proportional sensitivity signal S21 to the pH adjustor 22. The adjustor 22 outputs an absorbing agent supply flow rate correcting signal S22 to a coefficient adder 12, based on the signal S21, a detection signal from a pH adjustor 13 and a preset pH value. The adder 12 outputs an absorbing agent supply flow rate set point signal S12 to an absorbing agent supply flow rate adjustor 15, based on the signals S22 and S11, and the opening of a flow control valve 16 is adjusted on the basis of the signal S12.

摘要： PURPOSE:To prevent the increase in the concn. of outlet SO2 in excess of a guaranteed value by making a pH set value higher than a theoretical set value according to the rate of change in load in a transient period when load changes. CONSTITUTION:In a stack gas desulfurizer by a wet lime gypsum method, the signal from a detector 11 for flow rate of waste gases is inputted directly to an addition coefficient device 12 and is inputted to a differentiator 15 and coefft. adders 16, 17 as well. Then the output signal from the differentiator 15 is added to the signal from the detector 11 by the adder 16 and the signal through a code converter 19 is similarly added in the adder 17. Both signals are inputted to a high selector 18. Here the signals are selected according to the increase or decrease of load, and the selected signals are inputted to a function element 14 and are further operated to determine a pH set value, according to which the pH value of circulating liquid is controlled. Thus the desulfurizer is run stably under the assurance of the concn. of outlet SO2 by making the pH set value in the increasing or decreasing stage of load larger than the theoretical value.

CONSTITUTION:LPG liquid 2 through a feed pipe 3 is fed in a spraylike state into an evaporating drum 1 and pooled in the bottom thereof from which the liquid is supplied through a pipe 5 to a boiler 4. Then the liquid 2 in the boiler 4 is heated by hot water for evaporating, and then is returned in a gas-liquid mixed phase to the evaporating drum 1 through a pipe 6. The gasified vapor ascending in the drum 1 heats the liquid sprayed, a part of which is then condensed but the other part of which reaches to a demister 7, accompanying with the liquid droplets. After the droplets is removed in the demister 7, the vapouer is transferred through a pipe 8 to an LPG burning boiler. At this time, a rate of gas flow flowing through the pipe 8 is detected by a a flow detector 30 the outlet of which is used to control a flow regulator valve 18 for regulating the volume of steam heating a hot water heater 15.
