Abstract
The invention discloses an energy-saving chimney of a thermal power plant. The energy-saving chimney is tubular and composed of a chimney wall, a flue is formed on the inner side of the chimney wall, an interlayer is arranged between the outer side and the inner side of the chimney wall and is filled with water, and smoke heat exchanges heat with water in the inner layer via the chimney wall. Heat contained in the smoke can be effectively exchanged, energy utilization efficiency is improved, particles in the smoke after heat exchange can be reduced and resultantly air pollution is alleviated.
Description
Technical field
The present invention relates to a kind of chimney, specifically a kind of energy-saving chimney, can be used for the industrial enterprise such as steam power plant.
Background technology
Cogeneration of heat and power enterprise is domestic and international on record energy-conservation enterprise, but is again big power consumer simultaneously.Steam power plant is based on heat supply, and electricity is byproduct.The many heat supplies of steam power plant, the many economize energy of ability, many improve effects.Therefore, a lot of astute factory director extends heat supply network by every possible means, expands heating range, increases heating load, seizes heat supply market.Such behave not only reduces power generation and heat supply coal consumption, also improves Business Economic Benefit.But in the work of extension heat supply network, while guaranteeing heating quality, also to focus on the efficiency utilization of heat.
" brief talking the measure that steam power plant is energy-saving and cost-reducing " literary composition forms the production cost of steam power plant and analyzes: fuel cost 70%, material and water rate 5%, wage and welfare 3%, depreciation cost 12%, price for repairing 6%, other fees 4%, above data are found out, carry out economical operation and consume most important with reduction coal consumption, station service power consumption rate, various oil consumption and water.
These expenditures of steam power plant are absolutely necessary, but the utilization rate after expenditure is but most important energy-conservation link.As the flue gas containing amount of heat is directly discharged, heat not only pollutes environment in flue gas, and resource utilization is not high.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of steam power plant energy-saving chimney, the heat that this chimney can effectively utilize flue gas in flue to contain.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of steam power plant energy-saving chimney, forms tubular by chimney wall, is formed with flue inside chimney wall, be provided with interlayer, be perfused with water in described interlayer between the lateral surface of described chimney wall and medial surface.
In order to proper extension flue gas RT in flue, improve heat exchanger effectiveness, described flue is spirality.
Equally, in order to improve heat exchanger effectiveness, described interlayer is divided into spiral yarn shaped runner.
Chimney of the present invention can effectively by the exchange heat that contains in flue gas out, and improve the efficiency of using energy source, the flue gas after heat exchange reduces particle in flue gas, reduces the pollution to air.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the schematic diagram of chimney of the present invention.
Detailed description of the invention
A kind of steam power plant energy-saving chimney, as shown in Figure 1, forms tubular by chimney wall 2, is formed with flue 1 inside chimney wall 2, be provided with interlayer 3 between the lateral surface of described chimney wall 2 and medial surface, be perfused with water in described interlayer 3.
Flue gas with heat carry out heat exchange by chimney wall 2 and the water in interlayer 3, improve efficiency of utilization.Now, interlayer 3 should be suitable with the thickness inside chimney wall 2, otherwise can reduce heat exchanger effectiveness.In order to proper extension flue gas RT in flue 1, improve heat exchanger effectiveness, described flue 1 is spirality.
Equally, in order to improve heat exchanger effectiveness, described interlayer 3 is divided into spiral yarn shaped runner.
Chimney of the present invention can effectively by the exchange heat that contains in flue gas out, and improve the efficiency of using energy source, the flue gas after heat exchange reduces particle in flue gas, reduces the pollution to air.Water after heat exchange directly can pass into hot water pipeline, and supply utilizes.
Above-described embodiment does not limit the present invention in any way, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection scope of the present invention.
