Description

Technical Field

[0001] The invention relates to a water distributor, in particular to a tower-type equal-flow water distributor, belonging to the technical field of design and manufacture of cooling facilities. Background Art

[0002] In the metallurgical furnace body cooling, boiler water cooling, and flue gas cooling systems, it is very difficult to evenly distribute water, and evenly distributing cooling water to each cooling end is the key to ensuring the cooling effect. The prior art is to set a regulating butterfly valve and a flow meter on the main pipe or branch pipe, or to set a flow regulating valve to complete the cooling water distribution. If a regulating valve is set on each branch pipe, the cost is extremely high and the enterprise cannot afford it. In a more complex or large cooling water system, although a large amount of water can be used to eliminate the problem of uneven flow in the branch pipe and improve the effect of even flow and water distribution, there are problems such as high power consumption and difficulty in controlling the thermal balance in the furnace, and even cause faults such as arc deviation in a large DC furnace. Therefore, it is necessary to improve the prior art. Summary of the invention

[0003] In order to solve the problems of difficulty in uniform flow water distribution and high cost in existing large-scale cooling systems, the present invention provides a tower-type uniform flow water distributor.

[0004] The present invention is completed through the following technical scheme: a tower-type uniform flow water distributor, including a water supply main pipe, and a plurality of branch pipes connected to the cooling end, characterized in that the water supply main pipe includes a vertical upper thin pipe and a lower thick pipe, the upper thin pipe and the lower thick pipe are respectively connected to the inner sides of the upper and lower annular pipes through corresponding upper and lower horizontal connecting pipes, the outer sides of the upper and lower annular pipes are respectively connected to the corresponding and spaced-apart plurality of upper and lower water supply branch pipes, and the number of upper water supply branch pipes connected to the outer side of the upper annular pipe is less than the number of lower water supply branch pipes connected to the outer side of the lower annular pipe, so that the cooling water enters the upper thin pipe from the lower thick pipe to supply water, and the water flow is evenly distributed to the upper and lower branch pipes, and then the cooling water flow is made consistent through the throttling orifice plate.

[0005] The bottom end of the lower thick tube of the water supply main pipe is the water inlet end, and the top end of the upper thin tube is the closed end. The lower thick tube and the upper thin tube are connected by a tapered tube with a small top and a large bottom, and a top water supply branch is provided on the top of the upper thin tube to evenly distribute cooling water.

[0006] The diameters of the upper horizontal connecting pipe and the upper annular pipe are smaller than the diameters of the lower horizontal connecting pipe and the lower annular pipe, so as to evenly distribute the cooling water while ensuring the consistency of the cooling water pressure and flow.

[0007] The upper and lower water supply branch pipes have the same diameter, and the number of elbows and the bending angle of each water supply branch pipe are the same, so that the flow rate and pressure of cooling water entering the cooling end remain consistent.

[0008] The water supply branch pipe is provided with a throttling orifice plate, which includes two flanges arranged on the water supply branch pipe, and an orifice plate arranged between the two flanges and having a plurality of through holes thereon, and the number, shape and size of the through holes of each throttling orifice plate are the same, so that the flow rate and flow velocity of the cooling water flowing through can be controlled through the through holes, so that the flow rate and flow velocity of the cooling water flowing through each branch pipe are consistent.

[0009] The upper annular tube and the lower annular tube are provided with pressure gauges for detecting water pressure.

[0010] The present invention has the following advantages and effects: By adopting the above scheme, the pressure, flow rate and flow velocity of the cooling water flowing through the upper and lower branches can be easily kept consistent, so as to achieve the uniform flow distribution of the cooling water and ensure the normal and efficient operation of the cooling system. Since the device has a simple structure, it is low in cost and easy to install. It is indeed an ideal uniform flow water distributor. BRIEF DESCRIPTION OF THE DRAWINGS
