A domestic waste incineration tail gas treatment device according to an embodiment of the present invention is described below with reference to fig. 1 and 2.

According to the embodiment of the utility model, referring to fig. 1 and 2, the tail gas treatment device comprises a tower body 100, the tower body 100 is vertically arranged, the lower part of the side wall of the tower body 100 is provided with a lower air inlet 110, and a tail gas pipeline conveys tail gas into the tower body 100 through the lower air inlet 110; the top of the tower body 100 has an upper exhaust port 120, and the upper exhaust port 120 discharges the purified exhaust gas through an exhaust duct. The tower body 100 has a packing layer 200 therein, the packing layer 200 is located between the lower gas inlet 110 and the upper gas outlet 120, and the packing layer 200 is used for purifying the exhaust gas. In addition, tail gas device still sets up in the inboard vortex layer 300 and the guiding layer 400 of tower body 100 including the interval, and vortex layer 300 uses with the guiding layer 400 cooperation to make tail gas fully contact with filling layer 200, make tail gas obtain abundant purification.

In the embodiment, the turbulent flow layer 300 is a circular plate-shaped body, the turbulent flow layer 300 is located between the lower gas inlet 110 and the packing layer 200, and the exhaust gas passes through the turbulent flow layer 300 and flows to the packing layer 200. For the placement of the baffle 300, the baffle 300 has multiple layers of groups of flow holes 310 from its center to its edges. The branch hole group 310 is composed of a plurality of branch holes 311, the branch holes 311 are circularly arranged, and the diameters of the branch holes 311 are gradually increased from the branch hole group 310 at the inner layer to the branch hole group 310 at the outer layer; meanwhile, the flow guiding layer 400 is a circular plate-shaped body, the flow guiding layer 400 is disposed between the turbulent flow layer 300 and the lower air inlet 110, the central portion of the flow guiding layer 400 is provided with a circular air collecting hole 410, and the air collecting hole 410 is disposed opposite to the central portion of the turbulent flow layer 300, so that the tail gas rapidly flows to the cavity between the turbulent flow layer 300 and the flow guiding layer 400 through the air collecting hole 410 and flows to the central portion of the turbulent flow layer 300.

Specifically, through the arrangement of the flow guiding layer 400, the tail gas flows into the lower part of the inner side of the tower body 100 through the lower air inlet 110, and flows upwards to the central part of the turbulent layer 300 through the air collecting hole 410 at the central part of the flow guiding layer 400, so that the tail gas is uniformly dispersed all around and flows to the filling layer 200 through the flow dividing hole 311, and at the moment, the filling layer 200 is fully contacted with the tail gas, and the purification of the tail gas is completed.

Further, since the diameter of the branch holes 311 increases gradually from the inner branch hole group 310 to the outer branch hole group 310, the exhaust gas cannot rapidly pass through the branch holes 311 at the center of the turbulent layer 300, instead, the exhaust gas flows to the branch holes 311 of the outer branch hole group 310 along the lower surface of the guide layer 400, so that the exhaust gas is uniformly diffused in the tower body 100, and the exhaust gas sufficiently contacts the packing layer 200, thereby completing the purification of the exhaust gas.

In addition, the gas collecting holes 410 collect the tail gas between the diversion layer and the lower gas inlet 110, the collected tail gas flows to the turbulent layer 300, and in the tail gas collecting process, the gas collecting holes 410 improve the upward flowing force of the tail gas, so that the tail gas flows upwards quickly.

It is understood that the turbulent flow layer 300 may be provided in multiple layers, and each layer of the turbulent flow layer 300 gradually disturbs the flow of the exhaust gas, and the exhaust gas is diffused to the periphery, thereby achieving sufficient contact between the exhaust gas and the packing layer 200.

In some embodiments, the lower surface of the turbulent layer 300 is the first air guiding surface 320, the first air guiding surface 320 is an arc surface protruding downward, and the first air guiding surface 320 gradually protrudes downward from the edge to the center of the first air guiding surface, that is, the center of the first air guiding surface 320 is a vertex on the first air guiding surface 320, and the branch flow holes 311 of the branch flow hole group 310 are arranged around the vertex. Thus, when the first air guide surface 320 is configured as described above, when the exhaust gas flows to the vertex through the gas collecting hole 410, the exhaust gas diffuses from the vertex to the periphery along the inclined surface of the first air guide surface 320, and flows to the filling layer 200 through the diversion hole 311. It can be seen that the first air guiding surface 320 accelerates the tail gas to diffuse all around, and accelerates the tail gas to rapidly pass through the diversion hole 311, so that the tail gas can rapidly and sufficiently contact with the packing layer 200.

In a further embodiment, the upper surface of the turbulence layer 300 is the first concave surface 330, and the surface area of the turbulence layer 300 is increased by the first concave surface 330, so that more diversion holes 311 can be formed in the turbulence layer 300, the diversion holes 311 enable the spray water in the tower body 100 to be well dispersed, and the spray water sufficiently performs the tail gas purification.

In some embodiments, the lower surface of the flow guiding layer 400 is a second air guiding surface 420, and the second air guiding surface 420 is gradually recessed upwards from the edge to the air collecting holes 410, that is, the air collecting holes 410 are located at the highest position of the second air guiding surface 420; therefore, when the exhaust gas flows to the gas collecting hole 410, the exhaust gas flows to the gas collecting hole 410 along the second gas guide surface 420, so that the exhaust gas rapidly passes through the gas collecting hole 410.

In a further embodiment, the upper surface of the flow guiding layer 400 is a second concave surface 430, the second concave surface 430 is gradually concave downward from the edge to the gas collecting hole 410, and the second concave surface 430 and the second gas guiding surface 420 are symmetrically arranged with respect to the flow guiding layer 400, so that the purified water in the spray tower flows to the gas collecting hole 410 along the second concave surface 430, and the purified water after use can be discharged in time.

In some embodiments, the sidewall of the tower body 100 is fixed with an annular boss 130, and the annular boss 130 is used for the placement of the current guiding layer 400 and the current disturbing layer 300, respectively.

In some embodiments, the packing layer 200 has a plurality of layers, and the upper side of each packing layer 200 is provided with the shower head 210, respectively, so that the exhaust gas passing through the packing layer 200 is sufficiently purified by the purified water, and the exhaust gas discharged from the upper exhaust port 120 is less polluted.
