Problems solved by technology
In addition, coal dry stone, lime and gypsum calcium-based sulfur fixation are used in the boiler tank of the power plant. This method has low sulfur fixation efficiency and affects the coal combustion value, resulting in low furnace output, low thermal efficiency, and serious waste of resources.
The technical level of the combustion system of coal-fired furnaces is generally not high, and the thermal efficiency of operation is low, and the thermal efficiency is less than 65%, which is an important reason for serious pollution emissions

The invention relates to a circular heat-conserving energy-saving multi-purpose utilization environment protecting device which belongs to environment protecting devices and especially to environmentally friendly catalytic units for governing the Three Wastes (waste gas, waste water and waste residues). The circular heat-conserving energy-saving multi-purpose utilization environment protecting device comprises a furnace chamber and a chimney flue; the furnace chamber is provided with a combustion chamber therein; the combustion chamber is provided with catalyst beds which are assembled as a stepped fire grate; an automatic charger, a charging hopper, an automatic coal feeding mechanism and a gravity slag remover are provided outside the furnace chamber; a boiler is provided above the furnace chamber; the boiler is provided with a flue header; and two sides of the boiler are provided with flank passages. Key technology of the invention lies in that a plasma heater is provided in the charging hopper and anti-slag water tanks are provided on two sides of the combustion chamber; connecting water pipes, which connect with the anti-slag water tanks, are provided on four sides of the catalyst beds; heat-conservers are provided above the catalyst beds in the furnace chamber and under arch of the furnace chamber; a push rod is provided on the automatic coal feeding mechanism; and the push rod is connected with the stepped fire grate. The chimney flue is provided with an energy-saving water jacket and a multi-purpose utilization recovery device. The device of the invention can save energy fully and control discharge of pollutant.
Description
(1) Technical field: [0001] The environmental protection device for comprehensive utilization of cycle heat storage and energy saving belongs to the environmental protection equipment, especially the environmental protection catalytic equipment for treating the three wastes. (two) background technology: [0002] my country has so far used more than 600,000 boilers and more than 800,000 kilns. They are mainly layer-fired grate, followed by fluidized bed boiler tank and coal gas generator. In the process of coal conversion, that is, when coal is burned, the combustibles released under positive pressure are extremely wasteful, such as smelting iron and steel, electrolytic aluminum, building materials, papermaking, chemical leather, carbon industry and waste incinerators with high energy consumption and high pollution. Polycyclic aromatic hydrocarbons and dioxins (PCDD / Fs), represented by 3,4 benzopyrene (BaP) emitted, are strong carcinogens, teratogenic and even fatal hazards....
