Abstract
The invention relates to a waste heat utilization device for a petroleum coke calcination discharging furnace, in particular to a grid type waste heat recycling device for the petroleum coke calcination discharging furnace. The recycling device comprises the petroleum coke calcination discharging furnace, a tapered discharging opening formed in the lower portion of the petroleum coke calcination discharging furnace and an air sleeve wrapped outside the tapered discharging opening. A plurality of grids is arranged in the air sleeve in a staggered mode. The interior of the air sleeve is divided into a zigzag cavity body. The inlet end and the outlet end of the cavity body are connected with an air inlet pipe and an air outlet pipe respectively. A draught fan and a heating device are sequentially connected between the air inlet pipe and the air outlet pipe in series. Due to the fact that the tapered discharging opening is wrapped in the air sleeve, the temperature of materials in the tapered discharging opening is lowered by heating the air in the air sleeve, energy is taken away by the air and utilized by the heating device, reuse of the waste heat energy is completed, and the utilization rate of energy is increased.
Description
Technical field
The present invention relates to a kind of calcining petroleum coke discharging stove residual heat using device, particularly relate to a kind of calcining petroleum coke discharging grate grating waste-heat recovery device.
Background technology
Calcining petroleum coke discharging stove is the end of calcining petroleum coke, conical discharge port is provided with below calcining petroleum coke discharging stove, the petroleum coke after to calcining is needed to lower the temperature in conical discharge port position, existing way is outside conical discharge port, arrange temperature lowering water cover, then water in water jacket is discharged, its waste heat produced is not utilized, and produces the waste of the energy.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, provides a kind of calcining petroleum coke discharging grate grating waste-heat recovery device improving energy utilization rate.
The present invention is achieved by the following technical programs:
A kind of calcining petroleum coke discharging grate grating waste-heat recovery device, comprise calcining petroleum coke discharging stove, be located at the conical discharge port below calcining petroleum coke discharging stove and be coated on the wind cover of conical discharge port, multiple staggered grid is provided with in described wind cover, and wind is overlapped the cavity that inside division is complications, the import and export two ends of described cavity connect blast pipe and discharge pipe respectively, the air-introduced machine connected successively and adopt hot equipment of connecting between blast pipe and discharge pipe.
Described grid is for vertically to arrange along conical discharge port outer wall.
The invention has the beneficial effects as follows:
Due at conical discharge port outer cladding wind cover, by overlapping the heating of inner wind to wind, reduce the temperature of material in conical discharge port, its energy is taken out of by wind, and is adopted hot equipment utilization, completes the recycling of the waste heat energy, improves the utilization rate of the energy.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention.
In figure: 1. grid, 2. calcining petroleum coke discharging stove, 3. wind cover, 4. discharge pipe, 5. air-introduced machine, 6. adopt hot equipment, 7. blast pipe.
Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing and most preferred embodiment, the present invention is described in further detail.
As shown in the figure, the present invention includes calcining petroleum coke discharging stove 2, be located at the conical discharge port below calcining petroleum coke discharging stove and be coated on conical discharge port wind cover 3, multiple staggered grid 1 is provided with in described wind cover, and wind is overlapped the cavity that inside division is complications, the import and export two ends of described cavity connect blast pipe 7 and discharge pipe 4 respectively, the air-introduced machine 5 that connects successively and adopt hot equipment 6 of connecting between blast pipe and discharge pipe.In this example, learn by repeatedly testing, when described grid is for vertically arranging along conical discharge port outer wall, heat transfer efficiency is best.
Due at conical discharge port outer cladding wind cover, by overlapping the heating of inner wind to wind, reduce the temperature of material in conical discharge port, its energy is taken out of by wind, and is adopted hot equipment utilization, completes the recycling of the waste heat energy, improves the utilization rate of the energy.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
