Abstract
The utility model relates to an interior anti-corrosive smoke tube comprising a metal smoke tube and a polytetrafluoroethylene lining. A layer of polytetrafluoroethylene is lined on an ordinary smoke tube in a spraying or sectional bar affixing manner to prevent the smoke tube from being corroded by corrosive substances in the smoke gas, thereby greatly prolonging the service life of the smoke tube; besides, the exhaust gas temperature can be reduced without considering the dew point corrosion when the afterheat of the smoke gas is recycled after the problem of corrosion is solved, thereby improving the recycling efficiency of the afterheat; and the polytetrafluoroethylene is the smoothest material and is incompatible with ash, oil and water, accordingly, the inner wall can not be cleaned in the period of use.
Description
Technical field
The present invention relates to the smoke pipe in a kind of steam generator system, especially a kind of interior anticorrosion smoke pipe.
Background technology
The smoke pipe of the steam generator system of combustion of fossil fuels for improving the thermal efficiency, is provided with waste-heat recovery device, as " economizer " or air preheater, absorbs fume afterheat and reduces flue-gas temperature; Again in order to prevent " dew point corrosion ", all be provided with minimum exhaust gas temperature simultaneously, general oil-burning gas-fired boiler is 130 ℃, and coal-burning boiler is 180 ℃, and waste heat recovery efficient is low.
Summary of the invention
The present invention is intended to address the above problem, and a kind of simple scheme is provided, and realizes that smoke pipe prolongs smoke pipe service life, reduces the double effects of exhaust gas temperature (improving waste heat recovery efficient).
It comprises two parts, smoke pipe and liner wherein:
Smoke pipe is common smoke pipe, has the general utility functions and the structure of common smoke pipe; Key is to adhere to one deck polytetrafluoroethyllining lining by the mode of spraying or stickup section bar at the inwall of smoke pipe.
The advantage of the present invention and common smoke pipe is:
1, anticorrosion.The corrosion of smoke pipe is mainly in inside, and liner one deck polytetrafluoroethylene (PTFE) can be in steam generator system anticorrosion fully in useful life period;
2, for reducing exhaust gas temperature, improve waste heat recovery efficient and get ready.Can not consider " dew point corrosion " problem, improve waste heat recovery efficient more than 30%.
3, without deashing.Polytetrafluoroethylene (PTFE) is the most smooth material, with ash, oil, water is incompatible, can clear up inwall in the operating period.
From the economy angle, though smoke pipe cost height, the economic benefit of waste heat recovery and saving artificial and change the price difference of smoke pipe cost considerably beyond the present invention and common smoke pipe.
Description of drawings
Fig. 1 is a schematic diagram of the present invention, and Fig. 2 is smoke pipe and teflon-lined cutaway view.
1: smoke pipe; 2: liner.
The specific embodiment
Be described in detail with reference to the attached drawings the present invention, but the present invention is not limited to this embodiment.
Embodiment one
Embodiment two
Different with last example is: liner 2 is that the polytetrafluoroethylene (PTFE) sheet material with moulding sticks on smoke pipe 1 inwall.
Claims (1)
1. anticorrosion smoke pipe in a kind comprises smoke pipe (1), it is characterized in that:
The smoke pipe of metal material (1) inwall adheres to the liner (2) of one deck polytetrafluoroethylene (PTFE) material.
