Described feeding warehouse bottom also is provided with dump mouth and travelling car.
Adopt utility model, heat is burnt at pipe inside, water externally, and material and water reverse movement have completely cut off material and the direct of water and contacted, and have guaranteed performance of products and quality; Heat is burnt to be cooled under air-tight state, lossless; Improved burnt quality; Protect environment, do not had any disposal of pollutants; Hot water can use, and has practiced thrift the energy; Repair and install more convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The indirect cooler of a kind of petroleum coke comprises cooler cylindrical shell 7, and cylindrical shell 7 middle parts are provided with transmission device 6, and transmission device 6 is made up of pinion, the pinion of buncher drive speed reducer, reductor drive output and the gear wheel engagement that is installed on the cylindrical shell.Cylindrical shell 7 front and rears are respectively equipped with bracing or strutting arrangement 4,8.The forward and backward two ends of cylindrical shell are provided with feed arrangement and drawing mechanism and corresponding entrance lock 2 and discharging sealing device 11; Feed arrangement is a gravity type feeding warehouse 1; Use refractory material to water and build up inclination scraping wings 18, feeding warehouse 1 bottom also is provided with dump mouth 20 and travelling car 19; Drawing mechanism is made up of the air valve 14 of discharging cover 12 and discharging cover lower end.Cylindrical shell 7 front portions are provided with bulk refractory material scavenge unit 3, and cylinder back-end is provided with Inlet and outlet water joint 13, and flowmeter, Pressure gauge, thermometer are installed on the inlet channel, outlet conduit setting pressure table, thermometer.The water inlet end place at cylindrical shell rear portion is provided with rupture disk 10 and safety valve 9, the axial nested two-layer at least heat exchange inner core 5 that is provided with in the cylindrical shell 7, and heat exchange inner core 5 is coaxial setting.The heat exchange inner core is made up of boiler tube, is provided with fin 16, the screw propulsion heat exchange blade 17 of front portion and the spiral discharging blade 15 at rear portion in the heat exchange inner core 5.
The heat exchange inner core all adopts seamless boiler tube, adopts the technology of complete penetraction and fusion in welding, and the middle band steel that adopts uprightly welds, and is spaced apart, no interface in the middle of the heat exchange inner core; Barrel front end feeding warehouse place has built refractory material.
Burnt flow process: rotary kiln-tremie pipe-cooler feed arrangement-cooler heat exchange inner core-heat exchange-cooling agent discharging cover-air valve-belt feeder.
The flow process of cooling water: pond-water pump-cooler-oxygen-eliminating device-boiler.
Heat is burnt to get into cooler gravity type feeding warehouse through tremie pipe; And be stacked into certain altitude at gravity type feeding warehouse bottom periphery; Rely on the gravity effect to flow in the heat exchange inner core, the heat exchange inner core is interior through being welded with the anterior screw propulsion heat exchange blade and the spiral discharging blade at rear portion.The cooler cylindrical shell rotates under the driving of transmission device, and hot Jiao that screw propulsion heat exchange blade will get into heat exchange inner core front end takes away, and whenever rotates a circle, and advances a pitch, goes round and begins again, and hot Jiao who gets into is all brought in the heat exchange inner core.Heat is burnt advances in the heat exchange inner core, is kicked up simultaneously and rolls, and contacts with screw propulsion heat exchange blade with heat exchange inner core barrel and carries out heat exchange; Heat exchange method is heat conduction and heat radiation, because the heat transfer coefficient of heat exchange inner core is high, heat transfer rate is exceedingly fast; And the heat exchange inner core is outward a cooling water, Re Jiao and cooling water reverse movement, and the temperature difference is bigger; So be exceedingly fast from the burnt heat transfer of heat to cooling water; Heat is burnt to be cooled in airtight cylindrical shell very soon, and the cooling water that flows is heated simultaneously fast, is transported to the oxygen-eliminating device the inside.Boiler feed water is carried out heat exchange through the utility model earlier and is got into boiler again, saves the steam that boiler feed consumes, and boiler can not installed oxygen-eliminating device, has saved investment.
The effect of screw propulsion heat exchange blade is that promotion on the one hand and control material advance, and has increased heat exchange area on the other hand.The effect of spiral discharging blade is to stop that material glides fast and the burnt discharging speed of control heat.
