Abstract

An integrated box type pipeline structure of a regenerative heating furnace is applied to pipeline systems of air, coal gas, flue gas and the like of the regenerative heating furnace. Pipeline distribution can be improved, operation by workers is facilitated, and construction time is shortened. In the regenerative heating furnace, a coal gas or air main pipeline needing to be preheated and a flue gas main pipeline are integrated in a rectangular box. The box is divided into two chambers through a separation plate, wherein the chambers are not communicated, one chamber serves as a coal gas (or air) channel, and the other chamber serves as a flue gas channel. Flue gas branch pipes communicated with regenerative burners are led out of the flue gas channel, the flue gas branch pipe located on the same side together with the flue gas channel is directly led out of the side wall of the box and is connected with the corresponding regenerative burner, and the flue gas branch pipe located on the side different from the side where the flue gas channel is located is led out of the separation plate in the middle of the box, penetrates through the coal gas (or air) chamber and is connected with the corresponding regenerative burner. Coal gas (or air) branch pipes connected with the regenerative burners are led out of the coal gas (or air) chamber in the same mode as the flue gas branch pipes.

Description

The whole box-type pipeline configuration of recuperative heater

Technical field

The utility model patent relates to a kind of whole box-type pipeline configuration, is applied to the pipe-line system of recuperative heater.This structure can be used for, in the pipe-line systems such as air, coal gas and flue gas of gas preheating, air preheat and air and gas preheating of recuperative heater, can improving pipe arrangement, facilitates workman to operate, and shortens the engineering time.

Background technology

Recuperative heater, owing to having energy-saving and environmental protection, can use low-heat value gas, is widely used in China.But in use also have some problems, the pipe-line systems such as coal gas, air, flue gas that show as heating furnace are complicated, and pipeline and valve arrangement are more difficult, inconvenient operation, pipeline construction difficulty, the engineering time is long, and construction and production have been caused to adverse influence.

Summary of the invention

Complicated in order to solve the pipe-line systems such as coal gas, air, flue gas of recuperative heater, difficult arrangement, the problem such as the engineering time is long, constructional difficulties, the utility model has adopted a kind of whole box-type pipeline configuration.This structure not only can be simplified the pipe-line systems such as the coal gas, air, flue gas of recuperative heater and arranges, makes pipe arrangement become neat, attractive in appearance, handled easily, and can reduce difficulty of construction, shorten the engineering time.

The utility model addresses the above problem taked scheme: will in recuperative heater, need coal gas or the gas main duct of preheating to be integrated in the whole casing of a rectangle with the flue gas main pipeline that carries out with it heat exchange, with steel plate, casing is divided into two not connected chambers each other in casing, a chamber is as coal gas (or air) passage, be connected with outside corresponding coal gas (or air) main pipeline of casing, another chamber, as exhaust gases passes, is connected with the outside corresponding flue gas main pipeline of casing.The flue gas arm that leads to heat-accumulating burner is drawn from exhaust gases passes, directly from exhaust gases passes lateral wall, draws with the arm of exhaust gases passes homonymy, is connected with heat-accumulating burner; With exhaust gases passes not the flue gas arm of homonymy from the dividing plate at casing middle part, draw, through coal gas (or air) chamber, be connected with heat-accumulating burner.The coal gas connected with heat-accumulating burner (or air) arm is identical with the lead-out mode of flue gas arm from the lead-out mode of coal gas (or air) chamber.

The utility model beneficial effect is: the pipe-line systems such as coal gas, air, flue gas that can simplify recuperative heater are arranged, reduce pipeline and take up an area space, make pipe arrangement become neat, attractive in appearance, handled easily, and can reduce difficulty of construction, shorten the engineering time.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is the system schematic of whole box-type pipeline configuration in recuperative heater corresponding pipeline system.

Fig. 2 is the cross-sectional view of whole box-type pipeline configuration.

In figure, shown in heavy line and dotted line, part is the structure division of the utility model patent, shown in fine line, part is pipeline and the equipment being connected with the utility model patent, the content that does not belong to the utility model patent, only be used for illustrating itself and the utility model annexation in pipe-line system, concrete link position need actually be determined according to on-the-spot.The position of coal gas (or air) passage and exhaust gases passes can be according to on-site actual situations right and left mutually changing.

In figure: 1. coal gas (or air) arm; 2. flue gas arm; 3. heat-accumulating burner; 4. exhaust gases passes; 5. dividing plate; 6. coal gas (or air) passage; 7. coal gas (or air) main pipeline; 8. flue gas main pipeline.

The specific embodiment

As shown in the figure, the whole box-type pipeline configuration of recuperative heater is in recuperative heater, to need coal gas or the gas main duct of preheating to be integrated in the whole casing of a rectangle with the flue gas main pipeline that carries out with it heat exchange, with steel plate 5, casing is divided into two not connected chambers each other in casing, a chamber is as coal gas (or air) passage 6, be connected with outside corresponding coal gas (or air) main pipeline 7 of casing, another chamber, as exhaust gases passes 4, is connected with the outside corresponding flue gas main pipeline 8 of casing.So just make two or more pieces pipeline become a whole square chest, reduced the floor space of pipeline.The flue gas arm 2 that leads to heat-accumulating burner is drawn from exhaust gases passes, directly from wall box, draws with the arm of exhaust gases passes homonymy, is connected with heat-accumulating burner 3; With exhaust gases passes not the flue gas arm of homonymy from the dividing plate 5 at casing middle part, draw, through coal gas (or air) chamber 6, be connected with heat-accumulating burner 3.The coal gas connected with heat-accumulating burner (or air) arm 1 is identical with the lead-out mode of flue gas arm from the lead-out mode of coal gas (or air) chamber 6.Take after this structure, just avoided arm supervisor curve up and down wear around, make pipe arrangement become neat, attractive in appearance, handled easily has also reduced difficulty of construction simultaneously.Because casing can machine in advance, during body of heater construction, as long as the casing machining is put on support, be connected with each supervisor, arm, therefore also shortened the engineering time of body of heater pipeline.
