Efficient heat conduction wind furnace

Abstract

An efficient heat conduction wind furnace is composed of a combustion portion and a heat pipe collection portion. The combustion portion comprises a combustor, a combustion chamber and a lower fire observation furnace door, wherein a circulating air outlet is formed in one side of the top of the combustion chamber. The heat pipe collection portion comprises heat collection pipes, a combustion furnace hot smoke chamber and a waste smoke outlet, wherein one end of the combustion furnace hot smoke chamber is connected with the combustion chamber, the other end of the combustion furnace hot smoke chamber is provided with the waste smoke outlet, the combustion furnace hot smoke chamber is of a rectangular box body structure, the heat collection pipes are transversely and evenly arranged in rows and fixed to the combustion furnace hot smoke chamber, outlets of the heat collection pipes are connected to an interlayer hot air passageway outside the combustion chamber, and inlets of the heat collection pipes are connected with a circulation air inlet. The thermal efficiency of the efficient heat conduction wind furnace is high, and the temperature of the efficient heat conduction wind furnace is higher than the work temperature of a steam boiler and the work temperature of a heat conduction oil furnace, and can meet the requirement for the heating process at the temperature above 500 DEG C; the structure of the efficient heat conduction wind furnace is simple, and therefore the efficient heat conduction wind furnace can be more easily manufactured compared with a molten salt furnace, and is convenient to operate, safer and more practical; gas serves as the heat medium, and therefore production cost is low, economical benefits are remarkable, the requirement for the process at a high temperature can be met, the service life of the device can be prolonged, and the efficient heat conduction wind furnace saves energy and is environmentally friendly.

Description

technical field [0001] The invention relates to a heat-conducting blast furnace for heating various chemical equipments. Background technique [0002] Most petrochemical and dry distillation cracking equipment need to be heated at a temperature above 500°C. Generally, low-pressure steam boilers and heat-conducting oil furnaces are difficult to reach such temperatures. The heat-conducting medium with a heat-conducting working temperature above 500°C includes molten salt and liquid metal media, liquid The metal medium is relatively expensive, and the molten salt is generally liquefied at about 140°C, and the manufacturing cost of the equipment is high and the operation is complicated. It can become solid state immediately after cooling. When the operating temperature is improper or the power failure time is long, the pipeline is easily blocked and scrapped. After the operation is stopped, all the liquid molten salt should be put back into the molten salt tank. During the seco...

Problems solved by technology

Generally, in the rotary furnace heated by hot air, the hot flue gas is discharged after a one-time cycle, which results in large heat loss and low heat absorption rate, resulting in increased production costs.
