Description

A kind of air preheater dredger

Technical field

The utility model is related to a kind of air preheater dredgers, belong to dredging field.

Background technology

When carrying out denitration to the flue gas in boiler, air sky is easily blocked by the flyash in the flue gas of out of stock system Pre- device pipeline, is toasted using fume high-temperature, and flyash is hardened in the inside of pipeline, reduces the flow area of pipeline, makes pot Stove operational efficiency declines to a great extent, and operating cost increases.

At present pipeline inside dredge mainly using conventional tools such as reinforcing bar, impact drill, giants.Due to pipeline The internal existing hardness of tamper, and have viscosity, any existing method all can not complete dredging pipeline.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of air preheater dredger.

The air preheater dredger of the utility model, including pipeline, metal slice, valve and water pipe head；The pipeline bottom Portion is provided with notch, and the metal slice is welded in the notch, and the valve is mounted on the top of the pipeline, and the water pipe connects Head connects with the valve.

In one embodiment, the air preheater dredger further includes handle, is arranged on the pipeline.

In one embodiment, the metal slice is pointed shovel or flat shape shovel.

In one embodiment, the water pipe head is straight type or curved.

Air preheater dredger provided by the utility model, the metal slice of bottom can be by tamper inside air preheater pipeline It smashs to pieces, from water pipe head to the water flowing of pipeline inside, the tamper smashed to pieces is washed away in time, dredging air preheater can be carried out effective Dredging, maintain flow area stablize.

Specific embodiment

Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of air preheater dredger make it is further It is described in detail.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted that Attached drawing using very simplified form and using non-accurate ratio, only to it is convenient, lucidly aid in illustrating this practicality The purpose of new embodiment.

Embodiment 1

A kind of air preheater dredger of the utility model as shown in Figure 1, the air preheater dredger include pipeline 1, Metal slice 2, valve 3 and water pipe head 4.Notch is provided in the duct bottom, the metal slice 2 is welded in the notch, The tamper in air preheater pipeline is smashed to pieces by the metal slice 2.Specifically, the metal slice 2 can be pointed shovel peace Shape is shoveled, and specifically please refer to Fig. 1 and Fig. 2, Fig. 3 and Fig. 4, the valve 3 is mounted on the top of the pipeline 1, the water Pipe fitting 4 connects with the valve 3, for connecting external water source.The valve 2 is used to control water inlet switch and current size. By the water pipe head 4 to 1 inner inlet of pipeline, the tamper smashed to pieces is washed away.

It specifically, the air preheater dredger further includes handle 5, is arranged on the pipeline 1, makes staff convenient The air preheater dredger is caught to be operated.Further, please refer to Fig.1 and Fig. 3, Fig. 2 and Fig. 4, the water pipe head 4 It can be straight type or curved, be connected so as to which the air preheater dredger is facilitated with external water source.

Although the utility model has been described by way of example and in terms of the preferred embodiments, it is not limited to the utility model, any Person skilled in the art without departing from the spirit and scope of the utility model, can do various change and modification, therefore this The protection domain of utility model should be subject to what claims were defined.
