Cleaning agent comprising glycolic acid, citric acid and sulfamic acid for removing scales from heat exchange device of gas-gas heater used in desulfurization apparatus and cleaning method using the same

Abstract: PURPOSE: Provided is a cleaning agent for removing scales attached on the heat exchange device of a gas-gas heater used in a desulfurization apparatus, which removes the scales efficiently without any damages on the enamel coating of the heat exchange device. CONSTITUTION: The cleaning agent for removing scales from the heat exchange device of a gas-gas heater(GGH) used in a desulfurization apparatus comprises glycolic acid, citric acid and sulfamic acid as active ingredients. The cleaning agent optionally further comprises at least one selected from the group consisting of 5-sulfosalicylic acid, salicylic acid, ascorbic acid and tartaric acid. The cleaning agent is diluted with water at a ratio of between 1:5 and 1:15 and poured into a tank. The GGH heat exchange device is dipped into the tank to which air and steam are supplied, so that the scales are removed from the device.

Tubular GGH (gas-gas heater) system for thermal power plant

Abstract: The invention discloses a tubular GGH (gas-gas heater) system for a thermal power plant. The thermal power plant comprises a condensed water system. The tubular GGH system comprises a smoke gas cooler, a smoke gas heater, heat medium water and a condensed water heat compensator, wherein the condensed water heat compensator comprises a condensed water inlet, a condensed water outlet, a heat medium water inlet and a heat medium water outlet, the smoke gas cooler is communicated with the heat medium water inlet through fluid, a steam heater is communicated with the heat medium water outlet through fluid, the heat medium water circularly flows among the smoke gas cooler, the condensed water heat compensator and the smoke gas heater, and in the condensed water system, condensed water in different temperatures can flow to the condensed water heat compensator through the condensed water inlet, so that the heat medium water is heated or cooled, and then flows to the condensed water system through the condensed water outlet. The tubular GGH system has the advantages that the structure is simple, the investment is reduced, the control and regulation modes are simple, and the energy saving effect is realized.

Phenolated water treatment system implemented by using waste heat of gas stove

Abstract: The utility model discloses a phenolated water treatment system implemented by using the waste heat of a gas stove. The system comprises a gas stove, a cyclone dust collector, an air-cooled unit and a gas heater, wherein the gas stove is provided with a water jacket; a phenolated water inputting pipe of the heater is provided with a primary heater, a phenolated water outputting pipe is provided with a thermoregulator, and a phenolated water pipe connecting the primary heater, the gas heater and the thermoregulator is sleeved with a steam jacket. According to the utility model, on the basis of original pre-evaporating and burning treatment on phenolated water by using the sensible heat of the lower section of gas, the phenolated water is subjected to preheating, heating and heat insulation by using steam generated by the waste heat of the gas stove, so that the temperature of the phenolated water can be kept stable between 90 DEG C and 95 DEG C and the phenolated water can be used as an evaporating agent of the gas stove comprehensively; the energy consumption of the gas stove is reduced and the environmental pollution problem of phenolated wastewater is solved, thereby achieving the energy conservation and emissions reduction purposes of the gas stove.

Vapour-smoke heater for smoke desulfurizing

Abstract: The utility model relates to a steam-smoke gas heater for smoke gas desulphurization, which comprises an adjustable heater and is characterized in that the drainage side of the adjustable heater is provided with a drainage adjusting valve. The utility model changes the opening degree of the drainage adjusting valve to adjust the water level of the heater, and changes the temperature of the smoke gas outlet of the adjustable heater. On the premise of satisfying the discharging requirements, the utility model achieves the goal of saving energy. The utility model has the advantages that the steam-smoke gas heater can be controlled, and has good operation and energy saving efficiency.

Method and device for compressing gas

Abstract: PURPOSE:To reduce operation cost by a method wherein Stirling cycle is utilized to compress gas directly by heat energy. CONSTITUTION:The high temperature section 4 and the low temperature section 5 of a displacer cylinder 1 are communicated throgh a gas heater 6, a heat regenerator 7 and a cooler 8. A displacer piston 2 is provided in the displacer cylinder 1. The low temperature sectin 5 of the dispalcer cylinder 1 is connected to a low-pressure gas source 20 and a high-pressure gas source 21, both of them are out of the sytem, through nonreturn valves 23, 25. When the pressure in the low temperature section 5 is reduced lower than same of the low-pressure gas source 20, the gas is sucked from the gas source 20. On the contrary, when the pressure in the low temperature section 5 is increased higher than the same of the high-pressure gas source 21, the gas is discharged into the gas source 21. The gas may be compressed by repeating such motions.
