In order to ensure airtight pressure in cooling down the flow direction of water and maintaining airtight water cooling equipment, the height of described rhone 9 and the height of described return pipe 8 are less than the height of described gas water separation tank 3 delivery port, and the height of described settling tank 6 is less than the height of described rhone 9；The hydraulic pressure that the peak of described return pipe 8 produces is not less than the air pressure of the airtight water cooling equipment 1 of pressure box/distributing device.
As a kind of alternative embodiment, return pipe 8 described in the present embodiment cooling seal system being provided with the flowmeter 82 for monitoring cooling water flow, flowmeter 82 the most normally can work with display system；The temperature-detecting device 11 being arranged on the delivery port pipeline 12 of airtight water cooling equipment, for on-line monitoring outlet temperature, facilitates the water-cooled effect of judgement equipment.
The outfall sewer 2 that the present embodiment cooling seal system connects with gas water separation tank 3 can be a water pipe along water (flow) direction inclined design, so outfall sewer 2 just can connect airtight water cooling equipment 1 outlet conduit 12 of all pressure box/distributing devices thus all of outlet be cooled down after water gathers and enter gas water separation tank 3, and outfall sewer 2 is along water (flow) direction inclined design, equally avoids the deposition of impurity；For different equipment outfall sewers 2 the gradient can 1:10～1:5 (gradient ratio refer to height and length ratio) between, for the present embodiment is for pressure box/distributing device equipment, the slope design of outfall sewer 2 is about 1:10.
The present embodiment cooling seal system, by the control of the airtight water cooling equipment outlet system to pressure box/distributing device, realizes the cooling to pressure box/distributing device and sealing, and backwater is carried out purified treatment so that the utility model has the effect that
1, it is provided with gas and water separator, be conducive to because the gas being dissolved in the water in water-sealed equipment removes at gas water separation tank, meanwhile, UNICOM's muffler in gas water separation tank top Yu water-sealed equipment ensure that pressure balance between the two, it is simple to the removing of gas in water.
2, settling tank device it is provided with, the dust that is conducive to being dissolved in the water, impurity, the discharge of greasy dirt, improve the recycling of the water quality of backwater, beneficially water.
3, after this system Successful utilization, the effusion of pernicious gas in water-sealed equipment can be prevented by adjusting the absolute altitude pressure that control and stablize in water-sealed equipment of return pipe, and the consumption of outside pressurising medium can be reduced.
Embodiment 2
The present embodiment cooling seal system is to improve U-shaped pipe-line system on the basis of embodiment 1, realizes the blowdown of settling tank 6, moisturizing cleaning on the premise of the work not affecting system.
The present embodiment cooling seal system, is provided with communicating pipe, described communicating pipe is provided with coupling cock 13 between described settling tank water inlet pipe 5 and described return pipe 8；On described settling tank water inlet pipe 5 and described return pipe 8, the downstream in described communicating pipe is respectively arranged with switch valve 51,81, the blowoff valve 61 that the bottom of described settling tank 6 is provided with, the upper end air bleeding valve 62 of described settling tank.
In order to clean settling tank 6, described settling tank 6 is also associated with water replanishing device, and described water replanishing device includes filling pipe 7 tank connected with described precipitation and the water compensating valve 71 being arranged on described filling pipe.
When the present embodiment cooling seal system is properly functioning, as a example by the pressure box/distributing device of adjustment of Top Charging Equipment, its process is as follows:
1, gas-water separation process: after cooling water flows out from the airtight water cooling equipment 1 of pressure box/distributing device, converge and enter gas water separation tank 3 through outfall sewer 2, now, the gas being dissolved in cooling water in pressure box/distributing device will be moved out, and entered in the airtight water cooling equipment 1 of pressure box/distributing device by the return-air duct 4 on gas water separation tank 3 top, this ensure that stablizing of pressure in pressure box/distributing device, it also avoid the effusion of blast furnace gas in pressure box/distributing device simultaneously and security incident occurs.
2, U-shaped piping installation process: the settling tank water inlet pipe 5 along gas water separation tank 3 bottom is precipitated in switch valve 51 enters settling tank 6 by the water after gas separates, the dust dissolved in pressure box/distributing device is precipitated out, to purify water, subsequently, water after precipitation purifies enters in water return pipeline 8 by switch valve 81, and enter recycling in the rhone 9 being positioned at the setting of settling tank 6 top, now, the coupling cock 13 between settling tank water inlet pipe 5 and return pipe 8 is closed.Here, the peak absolute altitude of return pipe 8 can be arranged according to the pressure in pressure box/distributing device, it is ensured that the gas in pressure box/distributing device will not escape with water.
3, precipitation blowdown process: after system runs a period of time, need the things such as the mud in settling tank 6, impurity are cleared up, now, first turn on coupling cock 13, it is then shut off switch valve 51 and 81, later on air bleeding valve 62, finally opens blowoff valve 61 and carries out blowdown, and blowdown can be opened water compensating valve 71 after terminating and is rinsed settling tank 6.
4, settling tank moisturizing process: after blowdown process to be precipitated completes, first closes blowoff valve 61, is then turned on water compensating valve 71, till air bleeding valve 62 overflows water, it is then turned off water compensating valve 71, air bleeding valve 62, is then turned on switch valve 51 and 81, finally closing valve closing 13, whole system recovers normal work.
Precipitating the time used by blowdown process and settling tank moisturizing process in actual production process shorter, generally a few minutes are to ten a few minutes, so water quality is affected hardly during blowdown moisturizing.
The present embodiment cooling seal system is same as in Example 1, all can adjust by the gas pressure in water-tight equipment by adjusting return pipe elevation of top (H value in accompanying drawing), simultaneously enter and can be played, by the water in water-tight equipment, the effect that equipment (being particularly operated in the equipment of hot environment) is cooled down, it is achieved the double action sealing and cooling down.The present embodiment can also be further ensured that the water quality of backwater periodically to thing cleaning, discharges such as the mud in settling tank simultaneously.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that the utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim is defined.
