The invention discloses a technique for preparing sulfuric acid from SO2 by non-equilibrium state high-concentration twice conversion. SO2 flue gas is subjected to heat exchange twice through a heat exchanger and enters a first section of a converter to be subjected to conversion reaction; the filling amount of the catalyst for the first section of the converter is reduced so that the flue gas can leave the catalyst layer before reaching the SO2 equilibrium conversion rate; a waste heat boiler is arranged before the flue gas entering a second section of the converter to keep the temperature of the second section of the converter stable; the flue gas flows through the waste heat boiler and the heat exchanger to be cooled, and enters the second section catalyst layer of the converter, and at this time, the flue gas SO2 concentration is lower than 12%; the subsequent technique is equivalent to a conventional 3+1 twice conversion technique; and in the process, the temperatures of the first and second sections of the converter are lower than 640 DEG C. The technique can treat flue gas of which the SO2 concentration reaches 18% so as to lower the gross project investment and operating cost and enhance the steam output of the sulfuric acid waste heat boiler, thereby being an energy-saving consumption-reduction conversion technique.

A scroll compressor incorporates a vapor injection system where only one vapor injection port is utilized. The single vapor injection port injects refrigerant vapor into two of the initially formed enclosed spaces. The scrolls of the scroll compressor are designed with asymmetric wraps where the non-orbiting scroll wrap extends angularly further than the orbiting scroll wrap.

The invention discloses a closed high-efficiency evaporation-condensation instant water heater, which includes a controller, a box body, a buzzer, a water source, a supply device and a water outlet pipe; On the supporting frame supporting the perforated plate, a temperature sensor and a pressure sensor are arranged on the inner surface of the box, the output end of the temperature sensor and the output end of the pressure sensor are connected with the input end of the controller, and the output end of the controller is connected with the heater The control terminal and the control terminal of the buzzer are connected. The heating speed of the invention is fast, and the power of the heater is low and the volume is small.

The invention discloses a waste heat boiler for preparing olefins from methanol, which can meet various steam use requirements in a system for producing the olefins by the methanol. The waste heat boiler comprises a heat insulation hearth which is vertically distributed, a secondary heat exchange channel which is vertically distributed, and a main heat exchange channel which is connected with the upper end of the heat insulation hearth and the lower end of the secondary heat exchange channel; a smoke inlet is arranged at the lower end of the heat insulation hearth and a smoke outlet is arranged at the lower end of the secondary heat exchange channel; a plurality of super-heaters are arranged in the main heat exchange channel; a plurality of groups of economizers are arranged in the secondary heat exchange channel from top to bottom; the heat insulation hearth is located on the side wall above the smoke inlet and provided with a heat booster for improving a smoke temperature in the heat insulation hearth. The waste heat boiler provided by the invention has the advantages that: after the heat booster is additionally arranged on the side wall of the heat insulation hearth, the temperature of high-temperature smoke in the heat insulation hearth is raised, therefore, the temperature and the steam quantity of steam which is generated through the super-heater can be improved. The generation requirement and the most of the steam use requirements of the technology in the system for producing the olefins by the methanol can be met.
