A flue gas-treating method for treating acid tail gas by using an ammonia process, comprising the following steps of: 1) controlling the concentration of sulfur dioxide in an acid tail gas entering an absorber to be ≦30,000 mg / Nm3; 2) spraying and cooling with a process water or / and an ammonium sulfate solution in the inlet duct of the absorber or inside the absorber; 3) providing an oxidation section in the absorber, wherein the oxidation section is provided with oxidation distributors for oxidizing the desulfurization absorption solution; 4) providing an absorption section in the absorber wherein the absorption section achieves desulfurization spray absorption by using absorption solution distributors via an absorption solution containing ammonia; the absorption solution containing ammonia is supplied by an ammonia storage tank; 5) providing a water washing layer above the absorption section in the absorber, wherein the water washing layer washes the absorption solution in the tail gas to reduce the slip of the absorption solution; 6) providing a demister above the water washing layer inside the absorber to control the concentration of mist droplets contained in the cleaned tail gas. In the coal chemical industry, the integration of the Claus sulfur recovery process and the ammonia desulfurization technology can reduce the investment of the post-treatment and simplify the operation process, and provide intensive advantages to the environmental control of plants.

An air conditioning system for cooling or heating an air, and for feeding the heated or cooled air to predetermined portions is characterized by comprising: a first circulating circuit for circulating a first heating medium; a second circulating circuit for circulating a second heating medium; a control unit for controlling the heat for executing heat exchange between the first heating medium and the second heating medium to flow through either the heat exchanger or the first heat storing device. Moreover, an air temperature is controlled by heat of the second heating medium.

A heating and power generating apparatus comprises: a frame installed on the roof of a building and having a predetermined area; a plurality of power generating units arranged inside the frame to collect sunlight and generate electricity; and a hot water supply unit buried inside of the frame to absorb sunlight and perform heating and hot water supply. According to the present invention, hot water can be generated by sunlight in the winter to supply hot water and heat a house, and power can be generated by sunlight in the summer to supply power for cooling a room and thus conserve the electrical energy used in a cooler, thus promoting energy saving and environmental protection.

The configurations and adjusting method of a successive approximation analog-to-digital converter (SAR ADC) are provided. The provided SAR ADC includes at least one capacitor with a first and a second terminals, and a plurality of bits, each of which is connected to the at least one capacitor, wherein the first terminal receives an input signal, and the second terminal selectively receives one of a first and a second reference voltages, and a first comparator receiving an adjustable third reference voltage and a first voltage value generated by the input signal, wherein a connection of the second terminal of each the capacitor of the capacitor array is switched when the first voltage value is larger than the third reference voltage.

Information on a temperature of a heat generation member at a position which is in the neighborhood of an end portion of a conveyance area of a material, to be heated, having a maximum size and in the neighborhood of a non-conveyance area of a material, to be heated, having a size smaller than the maximum size is detected by temperature information detector, and a changer lowers a target temperature of the heat generation member depending on a detection result of the temperature information detector. Thereafter, when the detection result of the temperature information detector reaches a predetermined temperature, a magnetic flux adjusting member is started to be moved by a moving device.
