Description
Technical Field
The utility model belongs to the technical field of the heating furnace, especially, relate to a square chest heating furnace of indoor overhead calandria of radiation and radiation wall.
Background
In the petrochemical processing process, the heating furnace is the most basic and indispensable equipment and is also the key equipment which plays a determining factor for the production capacity of the petrochemical industry, and the heat load of the heating furnace directly determines the processing capacity of a petrochemical device, so that under the condition of the same size and structure, the improvement of the heat load of the heating furnace is particularly important. According to the current scientific and technical development situation, the heat load of the heating furnace in the petrochemical industry is closely related to the heat exchange area and the heat intensity of the furnace tube in the radiation chamber of the heating furnace. Because the upper space of the radiation chamber of the square box type heating furnace is larger, most of the flue gas directly enters the convection chamber, the radiation of the flue gas to the upper radiation furnace tube is smaller, and the average heat intensity of the upper part of the furnace tube is not improved. Therefore, the improvement of the heat intensity of the upper part of the furnace tube of the radiation chamber of the heating furnace is an effective way for improving the heat load of the heating furnace. The upper part of a radiation chamber of the existing square box heating furnace is not provided with a radiation wall, the temperature difference between the upper part and the lower part of a radiation furnace tube is large, the average strength of the furnace tube is low, the heat load of the square box furnace used in the petrochemical industry is large especially in the large-scale development of the existing petrochemical industry, the problem is more prominent, and the production capacity of the device is limited.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the problem and providing a square box heating furnace with a top calandria and a radiation wall arranged in a radiation chamber.
The utility model adopts the technical scheme as follows:
a radiation indoor set top calandria and radiation wall square box heating furnace, mainly by radiation chamber 2, convection current room 6 and chimney 7 fixedly communicate sequentially from bottom to top to form; radiation furnace tubes 3 are longitudinally arranged along the circumference of the inner wall of the square box-shaped furnace body to form a radiation chamber 2, the tops of the radiation furnace tubes 3 are arranged from two sides to the middle to form a valley shape, and a radiation wall 4 which is transversely arranged is arranged in the valley; the top of the radiation chamber 2 is transversely provided with an arrangement top calandria 5, the top calandria 5 is positioned above the radiation wall 4, and the top calandria 5 is communicated with the radiation furnace tube 3; the bottom of the radiation chamber 2 is provided with a burner 1.
As a further improvement of the present invention, the radiation wall 4 is cylindrical, and the cross section thereof is hexagonal.
As a further improvement of the utility model, the two side waist surfaces of the hexagonal cross section of the radiation wall 4 are provided with the observation holes.
The utility model has the advantages that:
(1) the space of the radiation chamber is fully utilized by additionally arranging the radiation wall in the furnace body. The radiant wall is added in the original space, so that the flue gas flows in the upper part, and the flue gas washes the furnace tube after being shunted, thereby increasing the heat transfer coefficient of the flue gas and the furnace tube. Thereby increasing the heat absorption capacity of the upper part of the radiant chamber furnace pipe, greatly reducing the exhaust gas temperature of the radiant chamber, improving the heat efficiency, effectively improving the heat load of the heating furnace, reducing the equipment investment, effectively improving the comprehensive efficiency of the heating furnace and improving the production capacity of the device.
(2) The calandria is added on the top of the radiation chamber of the heating furnace, so that the heat transfer area of the radiation chamber is increased, the relatively closed flue gas circulation is formed in the radiation chamber, and the heat absorption capacity of the upper part of the furnace pipe of the radiation chamber is greatly improved; the flue gas distribution and heating on the top of the radiation chamber are more uniform. The temperature difference between the upper furnace wall and the lower furnace wall in the vertical direction of the furnace tube is greatly reduced, thereby prolonging the service life of the furnace tube. The radiation chamber mainly transfers high-level energy radiation heat, so that the heat of the radiation chamber is fully utilized, the treatment capacity of the heating furnace is greatly improved, and the exhaust gas temperature of the radiation chamber is also reduced; the heating furnace has high heat efficiency, high heat load and less investment.
