Abstract
The utility model provides a square box heating furnace criss-cross multi-space tube pass radiation chamber, which belongs to a heating furnace radiation chamber, and is composed of a square box-shaped tube nest and a gridded coil. The square box-shaped tube nest is longitudinally and reciprocatedly coiled end to end to form a square box shape, the gridded coil is transversely and reciprocatedly coiled to form a square drawer board shape. The gridded coil is horizontally arranged on the upper mouth of the square box-shaped tube nest, the top of the square box-shaped tube nest is in a loop connection with the gridded coil to form a reversed box-shaped structure. A radiation chamber furnace tube is added in a furnace body to increase a heat interchanging area of the furnace tube and fully utilize a space of the radiation chamber without changing the furnace body overall structure size. A tube pass is increased in a limited space, the radiance of the upper portion of the radiation chamber furnace tube is also increased, and high potential energy is effectively used to greatly reduce smoke venting temperature of the radiation chamber and improve heat efficiency, thereby effectively improving heating load and comprehensive efficiency of a heating furnace, reducing equipment investment, and enhancing production capacity of devices.
Description
Technical field
The utility model belongs to the heating furnace radiation chamber, particularly relates to a kind of square chest heating furnace many spaces tube side radiation chamber in length and breadth.
Background technology
In the petrochemical industry process, heating furnace is the most basic, imperative equipment, it simultaneously also is the key equipment that petrochemical industry production capacity size is played decisive factor, the thermic load size of heating furnace is the working ability of decision petrochemical equipment directly, therefore, under the situation of comparable size structure, it is particularly important that the thermic load of raising heating furnace shows.According to present science and technology development present situation, the heat exchange area of heating furnace radiation chamber boiler tube and the thermic load of petrochemical industry heating furnace are closely bound up.Because the heating-furnace case takies finite volume, the surface heat intersity limitation of boiler tube fixes on certain limit, can not infinitely increase, and the boiler tube heat exchange area that therefore improves the heating furnace radiation chamber is the effective way that improves the heating furnace thermic load.And the inner boiler tube layout of existing heating furnace radiation chamber is unreasonable, does not make full use of furnace cavity, makes the interior heat transfer area of burner hearth less, has limited the production capacity of device.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of square chest heating furnace many spaces tube side radiation chamber in length and breadth is provided.
Square chest heating furnace of the present utility model is many spaces tube side radiation chamber in length and breadth, is to be made of square box shape tubulation and lattice drawer coil pipe.The vertical reciprocating disk of described square box shape tubulation is around, the formation that joins end to end square box shape, the horizontal reciprocating disk of lattice drawer coil pipe is tabular around constituting square drawer, lattice drawer coil pipe is horizontally placed on the suitable for reading of square box shape tubulation, and the dative drawer coil pipe phase loop, top of square box shape tubulation connects, and forms the shape of falling case configuration.
As further improvement of the utility model, described lattice drawer coil pipe be square planar laterally coil, connect with the loop mutually suitable for reading of the square box shape tubulation of vertically coiling and packing square box shape tubulation space, cross section suitable for reading.
As further improvement of the utility model, there is the connection of pipeline loop successively of the above shape of falling the case configuration of one deck to constitute many spaces tube side radiation chamber in length and breadth.
As further improvement of the utility model, lattice drawer coil pipe connects in the loop mutually with another square box shape tubulation of organizing tubbiness on its top in succession.
As further improvement of the utility model, the pipeline of adjacent two-layer lattice drawer coil pipe moves towards to overlooking cross-like.
Square chest heating furnace of the present utility model is many spaces tube side radiation chamber in length and breadth, reasonable in design, simple in structure, be under the prerequisite of original body of heater general structure size constancy, increase the boiler tube heat exchange area, make full use of the radiation chamber space by in body of heater, setting up radiating furnace tube.In limited space, strengthen tube side, also increased the radiance on radiation chamber boiler tube top, effectively utilize radiation chamber high potential heat, the big spoke degree of radiation chamber exhaust gas temperature is reduced, thereby thermic load, minimizing equipment investment that the thermal efficiency is improved and improves heating furnace effectively, improve the overall efficiency of heating furnace effectively, improved the production capacity of device.

The specific embodiment
Square chest heating furnace of the present utility model is many spaces tube side radiation chamber in length and breadth, is to be made of square box shape tubulation 1 and lattice drawer coil pipe 2.Described square box shape tubulation 1 vertical reciprocating disk is around, the formation that joins end to end square box shape, lattice drawer coil pipe 2 horizontal reciprocating disks are tabular around constituting square drawer, lattice drawer coil pipe 2 is horizontally placed on the suitable for reading of square box shape tubulation 1, and the dative drawer coil pipe 2 phase loops, top of square box shape tubulation 1 connect, and forms the shape of falling case configuration.
Lattice drawer coil pipe 2 laterally is coiled into square planar, connect with the loop mutually suitable for reading of the square box shape tubulation 1 of vertically coiling and packing square box shape tubulation 1 space, cross section suitable for reading.
Size and designing requirement according to heating furnace, the pipeline loop successively that the 1 dative drawer coil pipe 2 of the square box shape tubulation more than one deck can be constituted connects the shape of falling case configuration and constitutes many spaces tube side radiation chamber in length and breadth, as shown in Figure 1, lattice drawer coil pipe 2 connects in the loop mutually with another square box shape tubulation 1 of organizing tubbiness on its top in succession.The pipeline trend of adjacent two-layer lattice drawer coil pipe 2 is for overlooking cross-like, as shown in Figures 2 and 3.Utilize this apparatus structure single layer radiation chamber exhaust gas temperature can reduce about 100 ℃, reduce investment outlay about 10～15%, double-deck boiler tube radiation chamber can reduce about 300 ℃ of exhaust gas temperature meters, joint invests 25～30% less, improve the overall efficiency of heating furnace effectively, improved the production capacity of device.
