Abstract

The utility model discloses a novel exhaust flue device which comprises a flue neck and a gas hood, wherein the flue neck is connected with the gas hood, and the flue neck is in hollow bent tubular structure. The novel exhaust flue device abandons a method of common flue necks that frameworks are made of ordinary steel and refractory materials are laid on an inner wall, but adopts a structure that high-temperature resistance steel are directly used to manufacture the flue neck, and just a smoothing process is done and no refractory material lining is added inside a flue. The structure prevents dirt from stockpiling on the inner wall of the flue, and even if the stockpiling is a little, deformation of the flue wall through expansion and contraction enables the dirt to fall off, thereby being beneficial for circulation of smoke in the flue. In addition, bending radius of the flue neck is big, and therefore the circulation efficiency of the smoke in the flue is further guaranteed.

Description

A kind of novel exhaust flue device

Technical field

The utility model relates to a kind of novel exhaust flue device.

Background technology

As everyone knows, during the non-ferrous metal perrin process smelt to be produced, the structure of exhaust fume collecting hood directly had influence on the quality of the discharge efficiency and the final products of flue gas in the smelting process.

Along with the development of non-ferrous metal metallurgy technology, smelt production requirement for adapting to large-scale order, the researcher has designed portable petticoat pipe.This petticoat pipe compact conformation moves flexibly, can satisfy the needs that a large amount of non-ferrous metals is smelted in proper order.But because the flue gas that portable petticoat pipe needs to satisfy in the short period of time in one, the 20 stove smelting processes is collected and discharging; Cause the flue dust that in smelting process, contains in the high-temperature flue gas promptly to be bonded on the inwall of petticoat pipe, flue neck; Reduced the flue gas free air space in petticoat pipe and the flue neck; This flue gas that not only directly influences in the smelting process is collected and is handled, and also can cause flue gas to overflow in a large number owing to flue gas can not in time be collected discharge through flue.Flue gas overflow the pollution that not only can cause environment, also directly jeopardize operating personnel's health.

On the other hand, because perrin process is smelted discontinuity, the fluctuation that the temperature of petticoat pipe body can be violent, the refractory material of laying on the petticoat pipe inwall can come off, thereby can cause petticoat pipe to burn out maintenance difficult; In addition, flow of flue gas can cause the dust and dirt that bonds above the walling of flue in smelting process, constantly to come off to washing away of walling of flue, and the flue dust and dirt that these come off can cause adverse influence to the quality that molybdenum-iron is smelted.

Summary of the invention

For addressing the above problem, the purpose of the utility model provides a kind of novel exhaust flue device, and is simple in structure, practical, can guarantee flue gas in flue, circulate smooth and easy, can not accumulate a large amount of dust and dirt.

In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:

A kind of novel exhaust flue device comprises flue neck and petticoat pipe, and the flue neck is connected on the petticoat pipe, and said flue neck is the bend pipe structure of hollow.

Described novel exhaust flue device, the inwall of its flue neck is done smooth treatment.

Described novel exhaust flue device, its flue neck is processed by high temperature resistant steel.

Described novel exhaust flue device, its petticoat pipe inwall is equipped with refractory material.

Owing to adopt technique scheme, the utlity model has following superiority:

The utility model has been abandoned flue neck commonly used and has been used common iron to do skeleton; On inwall, lay the mode of refractory material, but directly use high temperature resistant steel to make the flue neck, only do smooth treatment in the flue and do not add refractory lining; This structure has prevented dust and dirt accumulating on the flue inwall; Even accumulating a little arranged, walling of flue comes off dust and dirt through the distortion of expanding with heat and contract with cold, and helps the circulation of flue gas in flue; In addition, the bending radius that the flue neck is bigger has guaranteed further that also flue gas is at the circulation efficiency in flue.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Among the figure: 1-flue neck; The 2-petticoat pipe; The 3-refractory material.

The specific embodiment

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

As shown in Figure 1, a kind of novel exhaust flue device comprises flue neck 1 and petticoat pipe 2, and flue neck 1 is connected on the petticoat pipe 2, and said flue neck 1 is the bend pipe structure of hollow, and the inwall of said flue neck 1 is done smooth treatment, is convenient to the circulation of flue gas and prevents to accumulate dust and dirt; Described flue neck 1 is processed by high temperature resistant steel; The inwall of said petticoat pipe 2 is equipped with refractory material, prevents that high-temperature flue gas from burning out petticoat pipe 2.

The bending radius of described flue neck 1 is according to the installing space at scene, strengthens in allowed limits as far as possible, helps coming off and reducing the resistance of flow of flue gas of flue dust and dirt like this. [0003]Key in summary of the invention herein and describe paragraph.
