Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the principle schematic of distributor water cooling plant of the present invention;
Fig. 2 is the structural representation of distributor water cooling plant of the present invention;
Fig. 3 is the A-A sectional view in Fig. 2.
Embodiment
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1-Figure 3, the invention provides a kind of water coolant in distributor rotator 10 internal recycling, rely on liquid level difference to provide the water cooling plant of circulation power, this device to comprise distributor rotator 10, distributor housing 11, enter aquaporin 1, water exit 2, enter tank 5, effluent trough 8, cooling channel, bottom 9, enter the composition such as tank water level detecting 3 and effluent trough water level detecting 7.
Enter aquaporin 1 through distributor housing 11, its function is that the exterior cooling water of low temperature is guided to inside.Water exit 2 is through distributor housing 11, and its function is that the internal cooling water participating in the rear high temperature of circulation is guided to outside.
Enter tank 5 and effluent trough 8, the annular housing that the two is with blast furnace medullary ray is center of turning circle, separate with upper spacer 6, it is characterized by, effluent trough 8 is positioned at into tank 5 outside, that is effluent trough 8 is encircled into tank 5, to pass through the high liquid level (HLL) trap heat into tank 5, prevent the high temperature deformation of rotator 10 withstand long term exposure.Enter tank 5, top connects into aquaporin 1, cooling channel, connection bottom, bottom 9.Effluent trough 8, top connects water exit 2, cooling channel, connection bottom, bottom 9.
Cooling channel, bottom 9, is the cavity of the accommodation water coolant of all heat affected zone of cardinal principle drape glassware rotator 10 inwall, it is characterized by, and from entering the water coolant that aquaporin 1 enters and the water coolant of discharging from water exit 2, flows respectively in different passages.
From the water coolant entering aquaporin 1 and enter, and from the water coolant that water exit 2 is discharged, flowing in different passages, is arrange realization by lower clapboard 18.Be provided with opening 12 at lower clapboard 18 and the inwall place of cooling channel, bottom 9, water coolant realizes converting discharge direction to by approach axis herein.
Opening 12 is arranged at the least significant end of cooling water circulation loop.In embodiment, from space, be also namely arranged at the lower-most point of rotator 10, outer most edge, otherwise will cause " short circuit ", the water route of its rear end cannot participate in circulation.
The function entering tank water level detection gauge 3 is the water coolant water level that continuous detecting enters in tank 5, and it can the various structures such as float-ball type, ultrasonic type, laser type, condenser type or method realize.
The function of effluent trough water level detection gauge 7 is the water coolant water level in continuous detecting effluent trough 8, same, and it can the various structures such as float-ball type, ultrasonic type, laser type, condenser type or method realize.
By entering the water coolant water level signal that tank water level detection gauge 3 and effluent trough water level detection gauge 7 detect, for water coolant water level control system, need reach following control effects: enter the water coolant water level in tank 5, higher than the water coolant water level in effluent trough 8, the difference of the two is H.The cooling water pressure entered in tank 5 produced by this waterhead H, for overcoming the loss of total pressure of cooling water circulation loop, and makes water coolant reach the flow velocity that can ensure rotator 10 cooling performance.
The maintenance of waterhead H extracted out from water exit 2 by high-temperature cooling water by outer loop pump, after heat exchanger cooling, then pumps into and realize into aquaporin 1.By controlling the rotating speed of outer loop pump, can control to draw water, the flow of pump water, thus the size of controlling water level difference H.
Further, distributor housing 11 is provided with channel of nitrogen 14, inner so that the nitrogen higher than gas pressure in stove is introduced distributor, plays and forms the effect that high pressure area intercepts dust-laden coal gas and supplement heat rejecter.
Further, be also provided with overflow weir 15 on the upper edge of upper spacer 6, it is circular or Long Circle hole, is communicated with into tank 5 and effluent trough 7, has multiple along rotator 10 circumference.When entering tank 5 inner cooling water water level and being too high, water coolant along overflow weir 15 overflow to effluent trough 7, thus will avoid water coolant from overflow inside rotator 10 in blast furnace.
Further, entering in tank 5 and effluent trough 7, be provided with capping 16, its entirety is annular round, makes, float on ullage with light material.Its function one is the contact area reducing liquid level and dust-laden coal gas, and two is suppress liquid fluctuating.
The present invention can realize providing circulation power by liquid level difference for water coolant, makes it be full of each position of cooling water channel completely, promotes cooling performance.Meanwhile, effective isolation of water coolant and the inner greasy dirt of distributor and dust can be realized, thus avoid the phenomenon such as fouling, blocking of cooling water channel.One-piece construction is simple, is convenient to safeguard, longer service life.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
