Abstract

The utility model discloses a device to use an atomized water to cool a sinter. Below an air inlet located at a blower, a cooling ventilation duct or an air box of a current cooler is equipped an atomized water device which comprises a general water inlet pipe 3, a filter 4, a flowmeter 5 or 51 or 52 or 53, a regulation valve 6 or 61 or 62 and an atomization sprinkler 7 or 71 or 72. Each regulation valve can be adjusted well in accordance with the production need or the equipment operation situation. The water from a general water inlet pipe 3, after filtered by the filter 4, enters the flowmeter 5 and then passes through the regulation valves and enters into the atomization sprinkler 7 or 71 or 72 which sprays the atomized water which mixes a cold airflow from the blower 1 and then enters the bottom layer of a hot sinter 9 at a cooler bogie 10 and passes through the hot sinter 9 wherein the atomized water is changed into a steam to carry away a large amount of heat, which can speed up the sinter cooling. Compared with a conventional cooling device, the atomized water cooling is characterized by a quick cooling and an increase of cooling capacity by 10 to 20 per cent, especially suitable for an application at a zone with a lower humidity.

Description

Agglomerate adds the atomized water refrigerating unit

Technical field the utility model relates to a kind of smelter high temperature sintering mining air and mixes with atomized water and carry out the refrigerative agglomerate and add the atomized water refrigerating unit, belongs to the F26B3/06 class.

The cooling in background technology smelter high temperature sintering ore deposit is that heat sinter is cooled to below 150 ℃ from 700～1000 ℃ of pressures, cold sinter not only helps the conveying and the finished product of agglomerate and handles storage, also can improve production area working conditions and reinforcing blast furnace smelts, improve furnace processor, reduce coke ratio, prolong furnace roof equipment life.The cooling apparatus of existing heat sinter generally has circular cooler and straight-line cooler, and heat-eliminating medium is a natural air.The speed of cooling of heat sinter is except relevant with the cooling power of equipment, and is also relevant with the water content in the natural air, and aqueous how much the variation with region, season, variation of temperature in the natural air.Because air specific heat is little, need a large amount of natural airs so cool off one ton of heat sinter.

Summary of the invention task to be solved in the utility model is to provide a kind of agglomerate to add the atomized water refrigerating unit under existing cooler condition, to improve the cooling power of cooler.

For realizing above-mentioned task, the technical solution adopted in the utility model is: each is installed and adds the atomized water device in the blower inlet place of existing cooler or cooler bellows or in the gas blower airduct, and this covering device mainly comprises under meter on water inlet arm, strainer and each road on water inlet manifold and each road, variable valve, atomizer, fixed link etc.The agglomerate of Gou Chenging adds the cooling performance that the atomized water refrigerating unit can improve heat sinter like this, plays the reinforcement cooling effect.

Adopt the sintering of as above technical scheme making to add ore deposit atomized water refrigerating unit, its advantage is: not limited by regional condition, be not subjected to atmospheric moisture and temperature difference, and all applicable; 2. suitably regulate the atomizing water yield and the pressure of each atomizer, can improve agglomerate cooling power 10～20%; 3. can save facility investment and reduce power consumption.

Description of drawings Fig. 1 is the device layout synoptic diagram that agglomerate described in the utility model adds the atomized water refrigerating unit, also is specification digest accompanying drawing of the present utility model.

Embodiment is described in further detail embodiment of the present utility model below in conjunction with accompanying drawing and embodiment.

As shown in Figure 1, agglomerate atomized water refrigerating unit described in the utility model divides two partly: original device partly comprises gas blower 1, cooling duct 2, cooler chassis 10, cooler bellows 11, bellows ash releasing tube 14, and bellows ash releasing tube 14 is installed in the bottom of cooler bellows 11; And newly add water inlet manifold 3 and

water inlet arm

31 or 32 or 33 are arranged partly, strainer 4, under

meter

5 or 51 or 53,

variable valve

6 or and 61 or 62,

atomizer

7 or 71 or 72,

fixed link

8 or 81 or 82, one of water inlet manifold 3 and strainer 4 is connected, its objective is that strainer filters out the physical pollutant that enters in the water inlet manifold 3 (if water quality is good, it is good not establish strainer 4), the other end of strainer 4 is connected with an end of under meter 5, one of under meter 5 connects water inlet arm 31, entrance end with under meter 53 of water inlet arm 31 joins, the exit end of under meter 53 is connected with the entrance end of variable valve 61, atomizer 71 is housed on the water pipe of the exit end of variable valve 61, shower nozzle quantity can a plurality of parallel connections, and atomizer 71 is connected with fixed link 81, and fixed link 81 is connected mutually with the inwall of cooler bellows 11.Another of under meter 5 connects water inlet arm 32, entrance end with under meter 52 of water inlet arm 32 is connected, the exit end of under meter 52 connects the entrance end of variable valve 6, be connected with atomizer 7 on the exit end water pipe of variable valve 6, and atomizer 7 usefulness fixed links 8 are connected in the cold-air duct 2.Airduct water shoot 15 is installed in the bottom of cooling duct 2.The 3rd of under meter 5 connects water inlet arm 33, entrance end with under meter 51 of water inlet arm 33 is connected, the exit end of under meter 51 is connected with the entrance end of variable valve 62, on the exit end water pipe of variable valve 62 atomizer 72 is housed, atomizer 72 usefulness fixed links 82 are connected, and fixed link 82 is connected mutually with the blast pipe inwall of gas blower 1.

When the heat sinter on the cooler chassis 10 9 needs cooling, at first connect the water coolant of supplying with from the production water supply pipe, water coolant enters through water inlet manifold 3 and passes through under meter 5 again after strainer 4 filters.According to producing needs or equipment running condition, can open

variable valve

6 or 61 or 62 simultaneously, and regulate the water yield and hydraulic pressure, mix the bottom that through cooler bellows 11 enter heat sinter 9 from

atomizer

7 or 71 or 72 atomized water that sprays simultaneously and the swiftly flowing cold wind that advances from gas blower 1 drum this moment, and pass agglomerate 9, take away the heat of heat sinter 9, reach the purpose of cooling agglomerate.If do not need to open simultaneously each atomizer, can close wherein some or certain several variable valve, open other one or several variable valve.For example close variable valve 6 or 61, open variable valve 62, after filtering through filter 4 from the water coolant of water inlet manifold 3 this moment again through under meter 5 from water inlet arm 33, enter under meter 51, the water coolant that comes out under meter sprays from atomizer 72 after the flow size of variable valve 62 its water coolants of adjusting.Mix in gas blower 1 with the cold wind while of blower inlet and become the moisture cold wind of high-speed cruising from the water coolant of atomizer 72 ejection, they enter the bottom of heat sinter 9 again in cooling duct 2 enters cooler bellows 11, and penetrate heat sinter 9, take away its heat, reduce its temperature, realize cooling purpose.
