The chimney can be mounted in an urban district or near a main artery, a billboard or other hanger are arranged around the chimney, thereby bringing good economic benefit, and structure is simple, mounting is convenient, maintenance is convenient and stability is good.

Description

A kind of chimney

Technical field

The utility model relates to a kind of chimney that discharges flue gas or waste gas.

Background technology

The function of chimney be with combustion emissions such as boilers to high aerial, reducing the air pollution concentration in the certain limit of ground, its draft simultaneously can increase the fuel economy of equipment such as boiler.Usually the stack cross section all is designed to circle, thus the best stress performance of implementation structure.But at some specific positions, as positions such as city proper or main arterial, the direct placement meeting of chimney directly influences the attractive in appearance of the appearance of the city, has destroyed the fine impression of visitor to the city.Therefore be necessary to design a kind of chimney, can not influence city look and feel, and bring certain economic benefits.

Summary of the invention

The purpose of this utility model provides a kind of chimney, can be installed in the urban district in city and major trunk roads, can around chimney billboard or other hanger be set, and can bring good economic benefit, and simple in structure, easy for installation, is convenient to safeguard good stability.

The purpose of this utility model is achieved in that a kind of chimney, comprises urceolus and at least one inner core, the triangular in shape or quadrangle in the horizontal cross-section of described urceolus.

Preferably, described inner core is steel inner cylinder or brick inner core.

Preferably, described urceolus is a reinforced concrete structure.

Preferably, be provided with support platform in the described chimney urceolus.

Preferably, be provided with hole for hoist and hoisting platform in the described chimney urceolus.

Preferably, be provided with between described chimney urceolus and the inner core and only shake device.

The utility model is owing to adopted above technical scheme, make it compared with prior art, have the following advantages and good effect: the stack cross section is designed to triangle or square, can be installed in the urban district in city and near the major trunk roads, can around chimney, billboard or other hanger be set, can bring good economic benefit.And simple in structure, easy for installation, be convenient to safeguard good stability.

Description of drawings

Fig. 1 is a triangle chimney schematic diagram of the present utility model;

Fig. 2 is a Square Factory Chimney schematic diagram of the present utility model.

The specific embodiment

As Fig. 1, shown in 2, a kind of telescopic or multibarrel chimney of the present utility model comprises at least one inner core 2, and the number of inner core 2 is one in the present embodiment, is steel inner cylinder or brick inner core.Inner core 2 is mainly used in the discharging flue gas.

Also comprise a urceolus 1, the horizontal cross-section of urceolus 1 (Fig. 1) triangular in shape or quadrangle (Fig. 2).

Urceolus 1 is a reinforced concrete structure, is mainly used in to bear wind load, earthquake load and support inner core 1 etc.

One cat ladder 3 is housed on the urceolus 1, is convenient to the workman and safeguards chimney.Also open some windows 4 on the urceolus 1 shown in Figure 2.

Generally establish support platform, hole for hoist and hoisting platform in the chimney urceolus 1, only shake device, the device that only shakes only limits the chimney horizontal displacement, but the vertical Free Transform still of chimney.

Bigger as chimney, also can establish inspection platform.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
