Background

In a metallurgical furnace body cooling system, a boiler water cooling system and a flue gas cooling system, the flow equalization and water distribution have great difficulty, and the key point for ensuring the cooling effect is that cooling water is uniformly distributed to each cooling end. In the prior art, a main pipe or a branch pipe is provided with a regulating butterfly valve and a flowmeter, or a flow regulating valve is arranged to complete the distribution of cooling water. If each branch pipe is provided with a regulating valve, the cost is extremely high, and enterprises cannot bear the regulating valve. In a complex or huge cooling water system, although the problem of uneven branch pipe flow can be solved by using a large amount of water, the uniform flow water distribution effect is good, the problems of high power consumption, difficult control of heat balance in a furnace and the like exist, and even faults such as arc deflection in a large-scale direct current electric furnace are caused. There is therefore a need for improvements in the prior art.

The lower thick tube bottom of water supply header pipe is for intaking end, last tubule top and be the blind end, links to each other through big end down's toper pipe between thick tube and the last tubule down to it is equipped with a water supply branch pipe to go up the tubule top, so that evenly distributed cooling water.

The pipe diameters of the upper horizontal connecting pipe and the upper annular pipe are smaller than those of the lower horizontal connecting pipe and the lower annular pipe, so that cooling water is uniformly distributed, and the pressure and the flow of the cooling water are consistent.

The pipe diameters of the upper and lower water supply branch pipes are the same, and the quantity and the bending angle of the elbow of each water supply branch pipe are the same, so that the flow and the pressure of cooling water entering the cooling end are kept consistent.

The water supply branch pipe is provided with a throttling orifice plate, the throttling orifice plate comprises two flange plates arranged on the water supply branch pipe and an orifice plate which is arranged between the two flange plates and is provided with a plurality of through holes, and the number, the shape and the size of the through holes of each throttling orifice plate are the same, so that the flow rate and the flow speed of cooling water flowing through each branch pipe are controlled through the through holes, and the flow rate and the flow speed of the cooling water flowing through each branch pipe are consistent.

And the upper annular pipe and the lower annular pipe are provided with pressure gauges for detecting water pressure.

The utility model has the advantages of it is following and effect: by adopting the scheme, the pressure, the flow and the flow speed of the cooling water flowing through the upper and lower support pipes can be kept consistent conveniently, the uniform flow water distribution of the cooling water is realized, and the normal and efficient operation of a cooling system is ensured. The device has simple structure, so the device has low cost and is convenient to install. The water distributor is an ideal flow equalizing water distributor.
