Abstract

The utility model discloses a heating furnace tube hanger, which is designed for overcoming the technical shortage of the furnace tube lower supporting structure and improving the economy of the heating furnace. The top of a double lug plate of the furnace tube hanger is connected with a cross beam through an upper pin shaft, the bottom of the double lug plate is a reversing lug plate with a plate surface vertical to the double lug plate, and a reinforcing rib plate is arranged at the reversing position of the lug plate; the reversing ear plates are connected with the hanging bracket through the lower pin shaft, and the furnace tube rows are fixed between the hanging plates of the hanging bracket. The furnace tube hanger is of a furnace tube upper suspension structure, and the reversing design of the lug plate can solve the problems of narrow top space of the radiation chamber and limitation of a beam structure. Because the hanger and the furnace tube bank expand downwards after being heated, the expansion supporting problem of the furnace tube does not need to be considered, and the length design of the oil transfer line from the convection chamber to the radiation chamber can be shortened as much as possible, so that the supporting investment is reduced, the manufacturing cost is reduced, and the economical efficiency of the trapezoidal heating furnace is improved. In addition, the installation, maintenance and disassembly of the furnace tube hanger are simple and easy to implement.

Description

Heating furnace tube hanger

technical field

The utility model relates to a furnace pipe hanger for a heating furnace, which belongs to the technical field of heating furnaces for oil refineries. the

Background technique

Since 2008, the large-scale delayed coking heating furnaces of domestic refining and chemical enterprises have mostly adopted the new double-sided radiation trapezoidal furnace type. Since the top of the radiation chamber is relatively narrow and long, and there are beams above the furnace tube, so the support structure under the furnace tube is often used. The furnace tube row expands upwards when heated, requiring a longer oil transfer line from the convection chamber to the radiation chamber to absorb the expansion, thus increasing the consumption of the furnace pipe rack. Since the furnace temperature is about 700-850°C, the furnace tube frame is mostly made of high-alloy materials, which is difficult to manufacture, heavy in weight, high in cost, and difficult to install, maintain and disassemble. the

Contents of the invention

The purpose of this utility model is to provide a heating furnace tube hanger, which can overcome the technical deficiency of the support structure under the furnace tube, reduce the cost of the support frame, and improve the economical efficiency of the heating furnace. the

The concrete technical scheme of the utility model is as follows:

The top of the double lug plate of the furnace tube hanger is connected to the beam through the upper pin shaft, the bottom of the double lug plate is the reversing lug plate perpendicular to the plate surface, and the reversing part of the lug plate is provided with a reinforcing rib plate. The reversing ear plate is connected to the hanger through the lower pin shaft, and the furnace tube tube row is fixed between the hanging plates of the hanger. the

The furnace tube hanger is a suspension structure on the furnace tube, and the reversing design of the lug plate can solve the problems of the narrow space on the top of the radiation chamber and the limitation of the beam structure. Since the hanger and the furnace tube row expand downward together after being heated, there is no need to consider the expansion support of the furnace tube, and the design of the length of the oil transfer line from the convection chamber to the radiation chamber can be shortened as much as possible, thereby reducing the support investment, reducing the cost, and improving The economy of the trapezoidal heating furnace. In addition, the installation, maintenance and disassembly of the furnace tube hanger are also simpler and easier. the
