Tube heating furnace for producing crude oil

Abstract

The invention discloses a tubular heating furnace for crude oil production, which comprises a furnace wall. A radiation chamber is arranged inside the furnace wall. A plurality of furnace tubes are respectively arranged inside the radiation chamber. Burners are arranged at the bottom of the furnace tubes. The top of the furnace is provided with a waste heat recovery tank, the inside of the waste heat recovery tank is provided with a waste heat recovery section, the top of the waste heat recovery tank is provided with a smoke exhaust pipe, the two sides of the furnace wall are provided with a cooling layer, and the top of the cooling layer is provided with a water pipe joint. One side of the joint is provided with a water pipe, the inside of the cooling layer is provided with a heat insulation layer, one side of the temperature insulation layer is provided with a cooling pipe, the inside of the cooling pipe is uniformly provided with a flow limiting plate, and one side of the cooling pipe is provided with a protective layer. This device solves the problem that the existing tubular heating furnace is prone to scald accidents due to the high temperature of the furnace wall during operation. The current ones are mainly protected by heat-insulating and heat-proof materials, which cannot dissipate heat and cool down, resulting in The heat protection effect is not obvious.

Description

technical field [0001] The invention relates to a tubular heating furnace, in particular to a tubular heating furnace for crude oil production, which belongs to the field of petroleum processing. Background technique [0002] Tubular heating furnace is a process heating furnace used in petroleum refining, petrochemical, coal chemical, tar processing, crude oil transportation and other industries. The material to be heated flows in the tube as gas or liquid, and is flammable and explosive. , the operating conditions are harsh, and at the same time, it operates continuously for a long period of time, and the heating method is directly exposed to fire. The exhaust gas temperature of the tubular heating furnace can be reduced to about 100°C to realize partial condensation of the acid-containing water vapor in the flue gas, and while recovering the low-temperature sensible heat of the flue gas, part of the latent heat of vaporization of the acid-containing water vapor can be reco...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome that the existing tubular heating furnace is prone to scald accidents due to the relatively hot furnace wall during work. Now the main methods are to use heat-insulating and heat-proof materials for protection, and Inability to dissipate heat and cool down, resulting in the problem that the heat protection effect is not obvious.
