Description

A kind of annular header of boiler

Technical field

The utility model belongs to boiler manufacture field, and in particular to a kind of annular header of boiler.

Background technique

The steam of boiler is flowed by the connection between upper collecting chamber and lower header, is connected to several pipes between upper lower header Son, and need to reserve a hole between upper lower header for installing combustor, natively not due to the distance between water pipe Width can only merge out an aperture toward both sides evacuation, and with the needs that combustor designs, the hole for needing to reserve also is required increasingly Greatly, the method for tradition toward both sides evacuation is unable to satisfy the needs of macropore.

In view of the above-mentioned problems, the header of macropore can be merged out it is necessary to study one kind is gone out, combustor installation can satisfy Needs.

Utility model content

The purpose of this utility model is that avoiding shortcoming in the prior art and providing a kind of annular collection of boiler Case, the annular header can merge out big hole for installing combustor.

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

There is provided a kind of annular header of boiler, the annular header includes upper collecting chamber, lower header and annular tube, described Upper collecting chamber, lower header and annular tube parallelly distribute on and the annular tube is between the upper collecting chamber and the lower header, The upper collecting chamber is connected to the annular tube by several first pipes, and the lower header passes through described in the connection of several second pipes Annular tube.

Wherein, the quantity of several first pipes is equal to the quantity of several second pipes.

Wherein, quantity >=10 of several first pipes and several second pipes.

Preferably, the quantity of several first pipes and several second pipes is 14.

Wherein, several first pipes and several second pipes correspond in line.

Wherein, tube bending radius R≤150mm.

Wherein, it is 10 ~ 16mm that first pipe, which protrudes into the depth H 1 of the upper collecting chamber,.

Preferably, it is 14mm that first pipe, which protrudes into the depth H 1 of the upper collecting chamber,.

Wherein, it is 10 ~ 16mm that second pipe, which protrudes into the depth H 2 of the lower header,.

Wherein, the annular header further includes several third pipes, and one end of several third pipes is connected on described The other end of header, several third pipes is connected to the lower header.

The utility model has the beneficial effects that the utility model includes upper collecting chamber, lower header and annular tube, the upper collection Case, lower header and annular tube parallelly distribute on and the annular tube is between the upper collecting chamber and the lower header, it is described Upper collecting chamber is connected to the annular tube by several first pipes, and the lower header is connected to the annular by several second pipes Pipe, the utility model can merge out macropore, can satisfy combustor installation.

Detailed description of the invention

Utility model is described further using attached drawing, but the embodiment in attached drawing does not constitute and appoints to the utility model What is limited, for those of ordinary skill in the art, without creative efforts, can also be according to the following drawings Obtain other attached drawings.

Fig. 1 is a kind of structural schematic diagram of the annular header of boiler of the utility model；

Fig. 2 is a kind of side structure schematic diagram of the annular header of boiler of the utility model.

In figure: upper collecting chamber 1, lower header 2, annular tube 3, upper drum 4, lower drum 5, the first pipe 101, the second pipe 102, third pipe 103.

Specific embodiment

The utility model is further described with the following Examples.

The annular header of a kind of boiler of the present embodiment, as shown in Figure 1, the annular header includes upper collecting chamber 1, next part Case 2 and annular tube 3, the upper collecting chamber 1, lower header 2 and 3 parallelly distribute on of annular tube and the annular tube 3 are located at described Between upper collecting chamber 1 and the lower header 2, the upper collecting chamber 1 is connected to the annular tube 3 by several first pipes 101, described Lower header 2 is connected to the annular tube 3 by several second pipes 102.

The present embodiment is connected to upper collecting chamber 1 and lower header 2 by one annular tube 3 of setting, the annular tube 3, in this way on The air-flow of header 1 and lower header 2 can realize convection current by annular tube, and can merge out a macropore, can satisfy burning The installation of machine.

In the present embodiment, it is all 14 that the quantity of the first pipe 101, which is equal to the quantity of the second pipe 102,.

The quantity that the first pipe is arranged is equal with the quantity of the second pipe, is conducive to the smooth outflow of gas；Quantity setting It is 14, installation of enough spaces for equipment such as combustors can be vacateed.

In the present embodiment, the depth H 1(that the first pipe 101 protrudes into the upper collecting chamber 1 is not shown) it is 14mm.

In the present embodiment, the depth H 2(that the second pipe 102 protrudes into the lower header 2 is not shown) it is 14mm.

The depth that first pipe and the second pipe protrude into lower header reaches 14mm, is conducive to enhance between pipe and header Air-tightness.

In the present embodiment, the annular header further includes 4 third pipes 103, described in one end connection of third pipe 103 The other end of upper collecting chamber 1, third pipe 103 is connected to the lower header 2.

It is connected outside upper lower header except through annular header, is also provided with the pipe for being directly connected to lower header from upper collecting chamber Son can adjust the setting of pipe according to the size of annular header.

In the present embodiment, as shown in Fig. 2, the first 101 radius of curvature R of pipe=150mm.

By the way that the bending radius of pipe is arranged, it can choose the fixation with annular header different location, do not need to be fixed on The outer wall of annular, facilitates the setting of pipe.

Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this The spirit and scope of utility model technical solution.
