As shown in fig. 1 to 3, the energy-saving and environment-friendly organic waste incineration device comprises a furnace body 1, wherein a feed inlet 11 is formed in one side of the furnace body 1, a crushing device 6 is arranged at the feed inlet, a grate 12 is arranged in the furnace body 1, and a flue gas outlet 16 is formed in the other side of the furnace body 1 away from the feed inlet 11; a heat exchanger 7 is arranged at the flue gas outlet 16, and a filtering device 8 is arranged between the front end of the heat exchanger 7 and the flue gas outlet 16;

when the energy-saving furnace is used, waste is crushed by the crushing device and falls into the feeding hole, then the waste is combusted on the grate, the combusted smoke rises and sinks along the baffle plate, ash in the smoke sinks to the bottom of the furnace body, then the smoke leaves the furnace body through the smoke outlet, tiny smoke dust in the smoke is further removed through the filtering device, finally, energy exchange is carried out through the heat exchanger, heat in part of high-temperature smoke is recovered, and the energy utilization rate is improved;

specifically, a crushing roller 61 is arranged in the middle of the crushing device 6, a filter screen 62 is arranged at the position, close to the feed inlet 11, of the bottom of the crushing device 6, an auger 63 for lifting is further arranged on one side of the crushing device 6, the bottom of the auger 63 is communicated with the side wall, close to the filter screen 62, of the crushing device 6, and the top of the auger 63 is communicated with the upper part of the crushing roller 61; the waste is crushed by the crushing roller and then is screened by the filter screen, falls into the furnace through the feed inlet to be combusted according to the requirement, is lifted by the packing auger to be transmitted to the upper part of the crushing roller according to the requirement, and is crushed by the crushing roller again; on one hand, the particle size of waste gas entering the furnace body is reduced, the combustion efficiency is improved, on the other hand, the effect of repeated crushing can be realized through the auger, and the uniformity of particles during combustion is guaranteed;

an arc slideway 13 is arranged on the right side of the grate 12, a first air inlet 2 is arranged below the feed inlet 11, and an air channel of the first air inlet 2 is arranged opposite to the arc slideway 13; when the crushed waste falls into the feeding hole 11, the organic waste is transversely blown into the furnace body 1 through the wind power of the first air inlet 2 and forms a rotational flow along the arc slideway 13 to carry out the up-and-down tumbling type combustion;

preferably, in order to facilitate better combustion, a second air inlet 4 is arranged at the bottom of the grate 12, a wind power regulating valve 41 is arranged at the second air inlet 4, and a pipeline of the second air inlet 4 is communicated with a combustion-supporting gas tank 5; the combustion-supporting gas in the combustion-supporting gas tank 5 is pumped into the furnace body by utilizing the wind power at the second air inlet 4, the second air inlet is provided with an air outlet which is gradually widened near the fire grate, a regulating valve at the second air inlet is used for regulating the air quantity of the mixed gas entering the furnace body, the mixed gas of air and combustion-supporting gas is fed into the furnace in the aspect of force, the combustion efficiency of waste is improved, on the other hand, the waste falling on the fire grate is slightly blown up, the waste is convenient to turn over under the wind power action of the first air inlet, and the waste on the fire grate is prevented from being accumulated to influence the wind power effect of the first air inlet;

furthermore, although the waste can be overturned and combusted in the furnace through the arc-shaped slide way, the waste quickly falls down to enter a new cycle, so that the retention time of the waste in a high-temperature area with small air volume in the furnace is short, the time for completely burning the waste out is prolonged, and the integral combustion is not facilitated; therefore, a hole-dredging screen plate 14 and a hole-densifying screen plate 15 are arranged on one side, close to the feeding port 11, above the fire grate 12, wherein the hole-dredging screen plate 14 is arranged above the hole-densifying screen plate 15, and the height of the hole-dredging screen plate 14 is lower than that of the upper end face of the arc slideway 13; when the net plate is used, wastes which are billowed upwards can fall onto the net plate and are combusted on the net plate, the wastes which are not billowed are gradually fallen from the upper net plate to the lower net plate according to different volume reduction of combustion degree, and the wastes which are not billowed continuously fall and then enter the arc-shaped slide way to be billowed continuously into a new cycle along with the newly entered wastes under the action of wind force; the double-layer screen plate can play a role in staged combustion, so that unburned waste falls layer by layer through the screen plate, the retention time of the waste in the furnace can be prolonged, and the waste can be ensured to be more sufficiently combusted; meanwhile, the double-layer screen plate is positioned at the part with smaller air volume in the furnace, so that higher temperature can be ensured to burn the waste out;

a perforated brick wall 3 is also arranged between the upper part of the fire grate 12 and the top of the furnace body 1, and the height of the perforated brick wall 3 is higher than that of the top of the arc slideway 13; therefore, heat accumulating type combustion is realized, on one hand, gas which is not completely burnt out can be partially combusted in the perforated bricks, on the other hand, the perforated bricks can accumulate heat, the temperature of a combustion area is maintained or increased, the efficiency of convective heat transfer and radiant heat transfer is improved, the full combustion of waste is promoted, and the generation of pollutants such as nitrogen oxides, dioxin and the like is reduced;

the filter device 8 at the smoke outlet comprises a filter screen mechanism 81 and a rotary shifting piece 82, after the whole combustion device runs for a period of time, a certain amount of dust is gathered on the filter screen in the filter screen mechanism 81, in order to not influence the normal work of the filter screen, the shifting piece on the filter screen is rotated and shifted at the moment, the filter screen rapidly swings back and forth in the filter screen frame by compressing a spring arranged on the filter screen mechanism frame, and the dust attached to the filter screen is removed by utilizing the pulse action of the spring; preferably, a layer of low-temperature catalyst can be added on the filter screen, so that the emission of nitrogen oxides can be effectively reduced, and the catalytic efficiency can be greatly improved by catalyzing at a relatively high temperature due to the high temperature of the emitted flue gas;

further, in order to recycle the heat in the high-temperature flue gas, the high-temperature flue gas enters a heat exchanger 7 for heat exchange after passing through a filtering device 8, so that the temperature recovery is realized, and the purposes of recycling energy and saving energy consumption are achieved;

preferably, in order to further utilize the residual temperature after heat exchange, the rear end of the heat exchanger 7 is communicated with the first gas inlet 2 and the second gas inlet 4 simultaneously; the connecting structure can not only ensure the temperature of the gas sent into the furnace body and avoid the low-temperature gas from entering the furnace body to influence the combustion efficiency, but also utilize the wind power as a corresponding power source and reduce the number of additionally arranged blowers;

in addition, a drying device 9 is arranged at the top of the crushing device 6, and the solid waste is dried before being crushed, so that the situation that the solid waste is too moist and cannot be ignited is avoided, and the situation that the contact between the waste and air is reduced due to the adhesion of the crushed fine solid waste caused by too high humidity is also avoided; preferably, the drying device 9 is communicated with the heat exchanger 7, so that the temperature of the flue gas after heat exchange can be fully utilized, and the energy utilization rate during drying is reduced.
