Abstract

The utility model relates to a pipeline structure of a chimney. The pipeline structure of the chimney comprises a pipeline channel which is composed of an upper cylinder body and a lower cylinder body, wherein the upper cylinder body and the lower cylinder body are mutually buckled. The lower cylinder body is provided with a smoke inlet and the upper cylinder body is provided with a smoke outlet. Hollow V-shaped cones with gradually larger cross area are arranged in the pipeline channel in the axis direction from the smoke inlet and the smoke outlet. The tops of the hollow V-shaped cones are hollow. Supporting plates are fixedly connected between the hollow V-shaped cones and the lower cylinder body. The pointed ends of the bottoms of the hollow V-shaped cones are fixedly connected with dust exhausting pipes which are communicated with the inner cavities of the hollow V-shaped cones. The dust exhausting pipes downwards incline and penetrate out of the lower cylinder body. Solid particles in smoke go upwards along with air currents and by means of the hollow V-shaped cones and the pipeline channel, the solid particles are subjected to resistance in the uprising process, fall into the inner cavities of the hollow V-shaped cones and are exhausted out of the dust exhausting pipes finally. Thus, drifting of the solid particles and forming of a chimney inner wall impurity layer are effectively relieved and pollution is relieved.

Description

A kind of pipeline structure of chimney

Technical field

The utility model relates to a kind of pipeline structure of chimney.

Background technology

Chimney of the prior art, when smoke evacuation, in air-flow, be often mingled with the solid particles such as dust granule, combustion impurities, along with the effect of air-flow is discharged in atmosphere, inner wall of stack is exerted a gradual, corrupting influence on for a long time simultaneously, often forms thicker impurity layer, and impurity layer is close to inner wall of stack vertically, more difficult removal, thus vicious circle formed.

Utility model content

The purpose of this utility model is to overcome the problem of above-mentioned prior art, and a kind of pipeline structure of chimney is provided, and it can effectively reduce the formation of flying away of solid particle and inner wall of stack impurity layer, reduces and pollutes.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of pipeline structure of chimney, comprise the pipe passage being formed by the upper shell mutually fastening and lower shell, described lower shell has into mouth, described upper shell has outlet flue, described pipe passage from described in enter mouth to being provided with the hollow V cone that area of section increases progressively in the axis direction of described outlet flue, the top hollow out of described hollow V cone, between described hollow V cone and described lower shell, be connected with gripper shoe, the bottom tip place of described hollow V cone is connected with ash releasing tube, described ash releasing tube is communicated with the inner chamber of described hollow V cone, described ash releasing tube is tilted to down and runs through and extend described lower shell.

Further, described in enter the area of mouth and the area of described outlet flue is roughly equal, described in the topside area of described hollow V cone is greater than, enter the area of mouth.

Further, the base plane of described hollow V cone is roughly concordant with the junction plane of described upper shell and lower shell.

Further, the bottom of described hollow V cone is entered the area of mouth described in equaling to the minimum clearance area of the inwall of described pipe passage.

The pipeline structure of a kind of chimney described in the utility model, comprise the pipe passage being formed by the upper shell mutually fastening and lower shell, lower shell has into mouth, upper shell has outlet flue, pipe passage is provided with the hollow V cone that area of section increases progressively from entering mouth to the axis direction of outlet flue, the top hollow out of hollow V cone, between hollow V cone and lower shell, be connected with gripper shoe, the bottom tip place of hollow V cone is connected with ash releasing tube, ash releasing tube is communicated with the inner chamber of hollow V cone, and ash releasing tube is tilted to down and runs through and extend lower shell.Solid particle in flue gas with air-flow upwards, through the effect of hollow V cone and pipe passage, solid particle is subject to resistance and drops in the inner chamber of hollow V cone in the process rising, finally from ash releasing tube, discharge, thereby effectively reduced flying away and the formation of inner wall of stack impurity layer of solid particle, reduced pollution.

Accompanying drawing explanation

Fig. 1 is the perspective structure figure of the pipeline structure of a kind of chimney described in the utility model;

Fig. 2 is the main TV structure schematic diagram of the pipeline structure of a kind of chimney described in the utility model.

The specific embodiment

According to drawings and embodiments the utility model is described in further detail below.

As shown in Figures 1 and 2, the pipeline structure of a kind of chimney described in the utility model embodiment, comprise the pipe passage 10 being formed by the upper shell 1 mutually fastening and lower shell 2, lower shell 2 has into mouth 21, upper shell 1 has outlet flue 11, pipe passage 10 is provided with the hollow V cone 3 that area of section increases progressively from entering mouth 21 to the axis direction of outlet flue 11, the top hollow out of hollow V cone 3, between hollow V cone 3 and lower shell 2, be connected with gripper shoe 4, the bottom tip place of hollow V cone 3 is connected with ash releasing tube 5, ash releasing tube 5 is communicated with the inner chamber of hollow V cone 3, ash releasing tube 5 is tilted to down and runs through and extend lower shell 2.

Enter the area of mouth 21 and the area of outlet flue 11 is roughly equal, the topside area of hollow V cone 3 is greater than into the area of mouth 21.The base plane of hollow V cone 3 is roughly concordant with the junction plane of upper shell 1 and lower shell 2.The bottom of hollow V cone 3 equals into the area of mouth 21 to the minimum clearance area of the inwall of pipe passage 10.

The foregoing is only explanation embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
