The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of biomass through pyrolysis charing of the utility model smoke removing device comprises: tank body 1, cover 2, walk smoke pipe 4, stagnant smoke pipe 3, absorption cell 6 and be contained in the alkaline absorption solution 7 in absorption cell 6, tank body 1 top is provided with opening, opening part is connected with cover 2 by screw thread, cover 2 middle parts are provided with pipe 21, one end of pipe 21 is through cover 2 and tank body 1 internal communication, and the other end is communicated with one end of walking smoke pipe 4 by screw thread; Tank body 1 and cover 2 are all placed on heating with in the furnace chamber 5 of Muffle furnace, and furnace chamber 5 is provided with steam vent 51, walks smoke pipe 4 and passes steam vent 51, and be fixedly connected with the furnace chamber 5 of Muffle furnace at steam vent 51 places.Walk smoke pipe 4 and pass after steam vent 51, by screw thread, be connected with the stagnant smoke pipe interface 31 at stagnant smoke pipe 3 tops, realize being communicated with of smoke pipe 4 and stagnant smoke pipe 3 inside; Stagnant smoke pipe 3 diameters are larger, and its bottom is open design, and the opening part of stagnant smoke pipe 3 is provided with bracing frame 32, and bracing frame 32 is positioned at the bottom of absorption cell 6, the below of the opening that makes stagnant smoke pipe 3 bottoms in alkaline absorption solution 7 liquid levels.
The operation principle of a kind of biomass through pyrolysis charing of the utility model smoke removing device is as follows:
First the living beings for the treatment of charing are put into tank body 1, then cover 2 is connected with tank body 1, and tank body 1 is put into together with cover 2 to the furnace chamber 5 of Muffle furnace, and connect to walk smoke pipe 4 and pipe 21, will walk smoke pipe 4 and pass and be fixed on steam vent 51 from steam vent 51; Stagnant smoke pipe 3 bracing frame 32 ends are put into absorption cell 6 down, in absorption cell 6, pass into alkaline absorption solution 7, extremely the opening of stagnant smoke pipe 3 bottoms is completely by alkaline absorption solution 7 submergences; By walking smoke pipe 4, be connected with the stagnant smoke pipe interface 31 at stagnant smoke pipe 3 tops, attended operation is complete.
The power supply of opening Muffle furnace starts heating, living beings in tank body 1 are carried out to thermal cracking carbonization operation, in heating process, the flue gas of tank body 1 interior generation enters stagnant smoke pipe 3 by walking smoke pipe 4, after part of smoke is cooling, becoming tar deposition gets off, remaining flue gas enters in alkaline absorption solution 7 from the opening of stagnant smoke pipe 3 bottoms, and in the process contacting with alkaline absorption solution 7, the acidic materials in flue gas are absorbed by alkaline absorption solution 7; Flue gas is after supercooling and alkaline absorption solution 7 absorptions, and a large amount of pernicious gases are absorbed, and the remaining gas being cleaned directly discharges.
As can be seen from the above embodiments, the utility model is walked smoke pipe 4 by employing flue gas is guided to stagnant smoke pipe 3, and finally passes in alkaline absorption solution 7, stagnant smoke pipe 3 is away from Muffle furnace, temperature is relatively low, and hotter flue gas enters after stagnant smoke pipe 3, becomes tar and precipitate after partial fume is cooling; Acidic materials in flue gas are absorbed by alkaline absorption solution 7, complete the purification to Muffle furnace tail flue gas, and finally discharge.Tank body 1 by cover 2 with walk smoke pipe 4 and be connected, arranging of cover 2 conveniently put into tank body 1 by living beings or from tank body 1 taking-up, cover 2 with walk smoke pipe 4 and be threaded connection, convenient for dismounting and washing tank body 1 and cover 2; Walk smoke pipe 4 and be connected with Muffle furnace at steam vent 51 places, avoided walking the generation that smoke pipe 4 was pulled and then caused smoke spillage phenomenon back and forth; Walk smoke pipe 4 and be threaded connection with stagnant smoke pipe interface 31, convenient disassembly, is convenient to clear up the tar in stagnant smoke pipe 3; Stagnant smoke pipe 3 opening parts are provided with bracing frame 32, guarantee on the one hand stable being placed in absorption cell 6 of stagnant smoke pipe 3, guarantee on the other hand to leave space between stagnant smoke pipe 3 bottoms and absorption cell 6 bottoms, facilitate the gas in stagnant smoke pipe 3 to enter alkaline absorption solution 7.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
