Description

A boiler water circulation partition structure

technical field

The utility model relates to a water circulation partition structure, in particular to a boiler water circulation partition structure.

Background technique

With the continuous rapid development of the national economy, "big" enterprises, hotels, guesthouses, schools, etc. continue to emerge, and the demand for large hot water boilers is increasing. With the increase of boiler capacity and the improvement of parameter requirements, the requirements of water circulation system are getting higher and higher. Especially for forced circulation systems, how to ensure the smooth flow of water channels is more and more important.

At present, hot water boilers are mainly based on natural circulation, the water flow speed is relatively slow, and the requirements for water flow distribution are also low. The water velocity of the forced circulation is relatively high, basically about 1m/s, so the boiler needs to be divided into multiple channels in series, and the interior of a header also needs to be divided into multiple sections, so the design of the middle partition is also very critical.

Contents of the invention

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a boiler water circulation partition structure which can make the boiler water flow channel more smooth and can also reduce sewage discharge, water drainage and exhaust interfaces.

The technical scheme adopted by the utility model to solve the technical problems: this boiler water circulation partition structure mainly includes a partition body, the upper part of the partition body has an upper gap, the lower part of the partition body has a lower gap, and the partition body is welded. Inside the header, the diameter of the bulkhead body is 1.5 mm smaller than the inner diameter of the header.

The upper notch and the lower notch are U-shaped or V-shaped.

The beneficial effects of the utility model are: the structure of the utility model can effectively isolate the header to ensure smooth flow, and can also reduce the setting of exhaust, water drainage and sewage discharge interfaces on the header to reduce costs.

Explanation of reference numerals: upper gap 1, lower gap 2, header 3, bulkhead body 4.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in the figure, this boiler water circulation partition structure mainly includes a circular partition body 4, the upper part of the partition body 4 has an upper gap 1, the lower part of the partition body 4 has a lower gap 2, and an upper gap 1 And the lower gap 2 is U-shaped or V-shaped. The upper gap is to connect the areas on both sides, so that exhaust can be performed uniformly; the lower gap is also to connect the areas on both sides, so that drainage and sewage can be performed uniformly. The clapboard body 4 is welded on the required position inside the header 3, and the diameter of the clapboard body 4 is 1.5mm smaller than the inner diameter of the header 3, which is convenient for installation. The thickness of the partition is selected according to the strength calculation and corrosion allowance requirements.

Weld this partition at the corresponding position of the header. The upper gap 1 on the top of the partition makes the two sides of the partition communicate with nearly 1% of the cross-section. If there is "gas" on the top of the header, it can be discharged uniformly through an exhaust port. The lower gap 2 at the lower end of the partition also makes the two sides of the partition communicate with nearly 1% of the section. If there are impurities and sewage at the bottom of the header, they can be discharged uniformly through a sewage or hydrophobic interface. The connection of 1% cross-section will not affect the distribution of water flow, and will not affect the normal operation of the boiler.

The utility model has the advantages of simple structure, reasonable design and low cost. It can not only ensure the reasonable and unobstructed water circulation process of the hot water boiler, but also ensure a certain connection between each circulation section of the boiler. .

In addition to the above embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the utility model.
