Detailed Description
The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.
The utility model provides a direct current dust removal waste incinerator, includes furnace body 1, feeder hopper 2 and exhaust pipe 3, its characterized in that: be provided with flue gas in the furnace body 1 and play rotary device 71, be provided with straight-flow dust collector on the exhaust pipe 3, straight-flow dust collector includes toper kuppe 5, dust collecting sleeve 6 and blast pipe 4, toper kuppe 5 is inside hollow coniform, the blast pipe 4 entry is just to the export of exhaust pipe 3, toper kuppe 5 sets up between exhaust pipe 3 export and the 4 entry of blast pipe, the most pointed directional exhaust pipe 3 of head of toper kuppe 5, dust collecting sleeve 6 is the sealed cover tube in both ends and sets up outside exhaust pipe 3 and blast pipe 4, the export of blast pipe 4 runs through dust collecting sleeve 6 end wall. The flue gas gets into smoke pipe 3 again behind smoke pipe 3 through flue gas rotation initiating device 71, upward movement in smoke pipe 3 internal rotation, the smoke and dust of big granule falls back to the stove intracavity again after slowing down through rubbing with smoke pipe 3 inner wall, remaining flue gas is in the whole dust collecting sleeve 6 that get into under the sheltering from of toper kuppe 5, turn over the edge of dust collecting sleeve 6 again and discharge by blast pipe 4, rotatory forward transport all the time of flue gas in this process, the flue gas again through with the effect of dust collecting sleeve 6 inner wall, with the effect of toper kuppe 5 inside wall, after the multistage separation, the smoke and dust clearance improves greatly. The conical air guide sleeve 5 throws all the flue gas to the periphery of the dust collecting sleeve 6, so that the situation that the flue gas near the rotating axis cannot be removed due to insufficient centrifugal force can be effectively avoided. The flowing process of the flue gas does not have secondary vortex formed in the traditional cyclone dust removal process, and the loss of airflow pressure drop is small.
The bottom of the dust collecting sleeve 6 is obliquely arranged, and the lowest part of the bottom of the dust collecting sleeve 6 is communicated with the feed hopper 2 through an ash discharge passage 61. Because straight-flow dust collector direct mount is on exhaust pipe 3, and the smoke and dust is not through the heat transfer cooling, still contains a lot of heats in the smoke and dust of separating, directly discharges and has formed the waste, discharges this part smoke and dust into feeder hopper 2, can effectively retrieve the heat, can also be through with the direct heat transfer of raw materials, partly with the moisture evaporation wherein, reduce the requirement of waste incinerator to the moisture content of fuel.
The top of the feed hopper 2 is provided with a gas collecting hood 21, and the top of the gas collecting hood 21 is communicated with the inlet of a primary air supply fan 8 of the furnace body 1 through a gas pipe 8. Because the garbage fuel contains a large amount of organic matters, the garbage fuel can generate foul smell, and smoke containing heat is mixed with the garbage fuel to promote generation of a large amount of odor, and the gas collecting hood 21 is additionally arranged to pump the odor away through the primary air supply fan 8 and send the odor into the furnace for combustion supporting, so that the problem can be well solved, and the degree of friendliness with the surrounding environment is improved.
The tip of the head of the conical air guide sleeve 5 is provided with an ash discharge hole 52, and the ash discharge hole 52 is communicated with the dust collection sleeve 6 through an ash discharge pipe 53. Because the smoke and dust can lose kinetic energy and separate out after rubbing with the inner wall of conical air guide sleeve 5 when turning back into blast pipe 4 through conical air guide sleeve 5 edge, this part of smoke and dust will fall into conical air guide sleeve 5 tip inboard finally, through setting up arrange ash hole 52 with its leading-in dust collecting sleeve 6 back unified discharge feed inlet, effectively prolong production cycle, reduce and maintain the frequency.
The contact part of the furnace body 1 and the smoke exhaust pipeline 3 is provided with a rotation starting cavity 7, the rotation starting cavity 7 is in a circular truncated cone shape, the bottom of the rotation starting cavity is connected with the furnace body 1, the top of the rotation starting cavity is connected with the smoke exhaust pipeline 3, and the smoke rotation starting device 71 is arranged in the rotation starting cavity 7. The inner cavity of round platform form is suitable for the air current and rotates, and big end down's overall arrangement does benefit to and forms the vortex simultaneously, and help the flue gas to start rotatory voluntarily, sets up in the chamber 7 of starting soon and triggers the air current rotatory, and rotary motion obtains strengthening behind the inner cavity of round platform form for the separation effect of flue gas obtains improving.
The flue gas swirling device 71 is a tangential air supply system or a guide vane type blade. According to specific combustion conditions, the guide vane type blades can well maintain the original temperature field in the furnace, and the two tangential air supply systems can effectively reduce the temperature of flue gas and are beneficial to protecting equipment.
The outer surface of the conical air guide sleeve 5 is provided with spiral air guide fins 51, and the spiral air guide fins 51 extend outwards from the head part of the conical air guide sleeve 5 to the tail part in a spiral mode. After the smoke acts through the smoke exhaust pipe 3, the rotation motion of the smoke is weakened, the spiral guide fins 51 can further enhance the rotation of the air flow when the air flow passes through, and thus, the smoke can keep enough rotation speed for separating the smoke after entering the dust collecting sleeve 6 and the conical guide cover 5. Because the center of the spiral guide fin 51 is different from the center of the conical guide cover 5, the smoke is in the process that the rotating radius is changed at any time in the contact process of the spiral guide fin 51, and the smoke with different grain diameters can be further separated in the contact process of the spiral guide fin 51.
The dust collecting sleeve 6 is provided with a complementary cyclone tube 62, the air inlet direction of the complementary cyclone tube 62 is along the rotation direction of the airflow in the dust collecting sleeve 6, and the complementary cyclone tube 62 is obliquely arranged from top to bottom to penetrate through the side wall of the dust collecting sleeve 6 and point to the gap between the conical diversion cover 5 and the exhaust pipe 4. Therefore, the direction of the air flow sent by the air supplementing pipe 62 is consistent with the direction of the air flow at the gap between the conical air guide sleeve 5 and the exhaust pipe 4, on one hand, extra power is provided for air flow rotation and conveying, on the other hand, the air supplementing pipe from top to bottom can help the flue gas to quickly turn to enter the conical air guide sleeve 5, so that the speed of the air flow entering the conical air guide sleeve 5 is accelerated, and the separation efficiency is also improved.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
