The specific embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is described.
The utility model provides a kind of dried slag Residual oil burner of oily sludge.This device comprises drying machine and flue washing device.The overall structure of drying machine is as shown in Figure 1, comprises the charging aperture 11 of the dried slag that contains Residual oil, and the discharging opening 12 of from drying machine, discharging behind the Residual oil all burnt in the dried slag.Discharging opening 12 is positioned at the bottom of drying machine.
The dried slag that contains Residual oil drops on the basin that carries dried slag after charging aperture 11 gets into the drying machine.Basin is a hollow structure.According to the embodiment of the utility model, as shown in Figure 2, drying machine has steam inlet 1 and steam (vapor) outlet 2, and the basin of hollow structure is connected with steam inlet 1 and steam (vapor) outlet 2, forms the steam channel of the superheated steam of 500C.In addition, dryer inner also is installed with the replenish air pipeline, and required air is carried in the burning that is used to Residual oil in the dried slag.According to the embodiment of the utility model, can the axle of basin be set to hollow structure with rake arm 3, expand the part of pipeline as air.
According to above-mentioned, the dried slag that falls into drying machine contains the oil content about 1%.These dried slags stand the superheated steam baking of 500 ℃ of high temperature in drying machine, under fresh slag and situation that air fully contacts, the oil content in the fresh slag begins to take place combustion phenomena.In stirring that does not stop and sufficiently long stoving time, the oil content in the dried slag is fully burnt, the heat energy that burning produces be dried machine and the dried slag absorption that contains Residual oil that newly falls into drying machine.After the heat that burning produces discharges, need not to feed the superheated steam heating, the heat energy that utilizes burning to produce is enough to keep burning to be continued to carry out, and does not need postcombustion again.And the dried slag oil-containing after the burning is lower than 0.3%, satisfies emission request.
Continuation according to the embodiment of the utility model, has a plurality of basins, the along continuous straight runs coaxial arrangement with reference to figure 2 in the drying machine.The charging aperture 11 of drying machine is positioned at the top of basin topmost.Above each basin, be provided with the rake arm 3 that extends along the radial direction of basin.Rake arm 3 and the coaxial setting of basin, and pivot.On rake arm 3, be fixedly connected with the rake leaf, the dried slag of oil-containing that is used to promote on the basin moves.According to the embodiment of the utility model, basin comprises that the diameter of first basin 5 that is arranged alternately along axis and second basin, 6, the first basins 5 is less than second basin 6.And the rake leaf 41 of first basin, 5 tops is along the radial direction setting of first basin, rake leaf 42 edges of second basin, 6 tops and the acutangulate direction setting of the radial direction of second basin 6.In addition, offer the middle blanking port 61 coaxial in the centre of second basin 6 with basin.
Referring to figs. 2 to Fig. 4.According to above-mentioned, the bake process of dried slag on basin is that the dried slag that contains oil content is fallen on the drier basin (present embodiment is first basin 5) topmost continuously.Having the rake arm 3 of harrowing leaf 41 turns over rake leaf 41 do gyration to copy dried slag continuously.The rotation of rake arm 3 drives 41 motions of rake leaf, and rake leaf 41 promotes dried slag and moves.Dried slag rotates along the axle center of basin again along moving, harrow simultaneously leaf 41 perpendicular to the direction of rake leaf 41, and final dry matter is harrowed the radial direction that leaf 41 pushing away to basin and moved.Because the rake leaf of first basin 5 and second basin, 6 tops is different with the angle of rake arm 3, so dried slag is also different with the motion track on second basin 6 at first basin 5.Particularly, the dried slag on first basin 5 outwards moves to the outer rim of basin, and the outer rim of second basin 6 below outer rim is fallen; And dried slag moves inwards and falls into one deck first basin 5 down from middle blanking port 61 on second dry pan.First basin 5 and second basin, 6 alternatively up and down are arranged, and dried slag is able to flow through continuously each basin in the drying machine, thereby has fully guaranteed the stoving time long enough of dried slag in drying machine, and the burning of Residual oil is enough thorough.In addition, thermocouple is equipped with in the basin below, can survey the temperature in the drying machine and send temperature indication signal.Fully the dried slag after the burning is fallen the bottom of housing from last one deck basin, is shifted into discharging opening 12 at last and discharges.
According to the embodiment of the utility model, rake arm 3 has a plurality of, and evenly is provided with along the circumference of basin.An embodiment according to the utility model extends at basin in the radial direction, and the rake arm 3 more smaller than the diameter of basin has three.According to the embodiment of the utility model, be fixedly connected with a plurality of rake leaves on each rake arm 3.So, can improve the rake leaf and promote power and the efficient that dried slag moves.
In addition, as shown in Figure 5, the dried slag Residual oil burner of the oily sludge of the utility model also comprises flue washing device 20, is used to reclaim the flue gas that Residual oil burning back produces.Flue washing device mainly comprises gas approach 201, tail gas outlet 202, cooling water inlet 203 and coolant outlet 204.Its operation principle does, flue gas is fed by gas approach 201, and clear water feeds from cooling water inlet 203 endlessly.Be provided with dividing plate in the flue washing device, contact area and reaction time with flue gas fully moisturize.Flue gas is discharged from tail gas outlet 202 after washing, thereby reaches emission request.Particularly, the top of the utility model drying machine offers waste gas outlet 10, and the waste gas that the Residual oil burning back in the dried slag produces is discharged from this outlet.The waste gas outlet 10 of drying machine is connected with the gas approach 201 of flue washing device 20, can realize the non-pollution discharge of flue gas.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
