Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is A-A sectional view in Fig. 1.
Wherein：1 is shaft preheater, and 2 is rotary kiln, and 3 is relief valve, and 4 is water tank, and 5 is cooler, and 6 is water inlet pipe, 7
For water inlet control valve, 8 is feed pump, and 9 is support, and 10 is outlet pipe, and 11 is outlet water control valve.
Specific embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
As shown in Figure 1-2, a kind of rotary kiln body surface face waste-heat recovery device that the present invention provides, including water tank 4, support
9th, water inlet pipe 6 and outlet pipe 10, wherein water tank 4 are arranged at the outside of rotary kiln and are supported by support 9, and described water tank 4 sets
There are water inlet and outlet, described water inlet pipe 6 is connected with the water inlet of described water tank 4, described outlet pipe 10 and described water tank 4
Outlet connects.
The water inlet of described water tank 4 and outlet are symmetricly set in its both sides, and described water inlet pipe 6 is provided with water inlet control valve
7 and be connected with feed pump 8, described outlet pipe 10 is provided with outlet water control valve 11.Described water tank 4 is provided with relief valve 3.
In one embodiment of the invention, described water tank 4 is semicircle airtight water tank, and described water tank 4 is sleeved on rotary kiln 2
Gap is left, described relief valve 3 is arranged at the top of described water tank 4 between top and the outer surface of inner surface and rotary kiln 2.
The operation principle of the present invention is：
Using the heat radiation of rotary kiln 2 kiln body, through a semicircle airtight water tank 4, (volume about 21m3) absorb waste heat, mesh
Be that normal-temperature water about 20T in water tank is heated to 65 DEG C, this heating water can enter to worker's bathing pool and kiln operation room post
Row heat supply in winter.
Embodiment
Water tank 4 is semicircle seal case, and its overall diameter is φ 4700mm, and interior diameter is φ 4500mm, and length is
15000mm, using the fulcrum on the contact surface two ends of semicircle bottom, makes four metal racks and carrys out static housing.
In the peak of water tank 4, an air venting relief valve 3, the water inlet pipe 6 in the left and right sides of casing 4 and going out are installed
Water inlet control valve 7 and outlet water control valve 11 are respectively mounted on water pipe 10, for controlling water inlet and water outlet, and are entered by feed pump 8
Row supplies water.
The steam of certain volume when rotary kiln 2 radiation temperature is too high, or when water consumption is few, can be formed in water tank 4, when
When steam pressure reaches certain numerical value, pop off valve 3 automatic deflation, play a protective role to water tank 4 with water personnel.
The present invention, due to make use of the waste heat of rotary kiln kiln body it is not necessary to start coal-burning boiler, has saved the consumption of fire coal,
Decrease cost of labor and certain power consumption.Need to calculate according to warming, bathing etc., daily 5 tons of raw coal of saving, often
Ton market average price is 600 yuan, then monthly save fund=5*600*30=90000 unit, and the Northeast's heat supply in winter presses 5
The moon calculates, and annual winter saves fund=90000*5=450000 unit；Other seasons are only responsible for bathing, save 2 tons of coals daily,
Then non-winter saves fund=2*600*30*7=252000 unit every year；Amount to saving fund=450000+252000=every year
70.2 ten thousand yuan, ten thousand yuan of the cost of labor=3000*12=3.6 of saving.By this technological invention, save 73.8 for enterprise every year
Wan Yuan, annual minimizing consumes 74 tons of fire coals, converts into 52.8 tons of mark coals；Reduce about 29.6 tons of waste sludge discharge.Reduce discharge CO simultaneously2
=2.6*52.8=137.3 ton, SO2=0.0085*52.8=0.45 ton；NOX=0.0074*52.8=0.39 ton；For country
Administer air, environmental pollution engineering makes major contribution.
The foregoing is only embodiments of the present invention, be not intended to limit protection scope of the present invention.All in the present invention
Spirit and principle within made any modification, equivalent substitution and improvement, extension etc., be all contained in protection scope of the present invention
Interior.
