Problems solved by technology

The rotating and moving kiln body moves forward on the track at a speed of 70m / d~l20m / d, the front end "eats" the brick adobe, and the rear end "spits out" the finished brick, and completes drying-preheating-roasting-cooling- —The whole process of brick production. This kind of circular mobile brick kiln has a large output and high efficiency. It is very popular in the market at present. The desulfurizer and desulfurization tower on the power plant or boiler are used for flue gas treatment. Since the water circulation system and desulfurization tower of the existing desulfurizer are installed separately, the site covers a large area, and the installation is time-consuming, requiring a lot of manpower and material resources. , the equipment cost is high, and the maintenance is difficult, which is not conducive to popularization and use. Therefore, there is an urgent need for a simple, practical, and low-cost brick kiln flue gas dedusting and desulfurization device that matches it.

Embodiment 1

[0068] Embodiment one, see figure 1 , figure 2 , Figure 21 , Figure 22 , the movable kiln body 1 is divided into the kiln body section 104 in the drying area, the kiln body section 103 in the preheating area, the kiln body section 102 in the roasting area, and the kiln body section 101 in the cooling area. The chimney discharge area 105 is set in the kiln body in the drying area end of segment 104, figure 2 Shown is a schematic diagram of the structure of the dust removal and desulfurization device inside the kiln body. The dust removal and desulfurization device is installed in the kiln body section 104 of the drying area, and the closed drainage hood 301 is fixedly installed on the top of the kiln body at the smoke discharge area 105. The top of the kiln body at the discharge area 105 is covered therein and extends for a certain distance along the direction of the kiln body section 103 in the preheating area. The top of the end of the closed drainage hood 301 is provi...

Embodiment 2

[0069] Embodiment two, see image 3 The difference between the present embodiment and the first embodiment is that: in the present embodiment, a sedimentation tank 313 is provided next to the reaction raw material pool 310, and an overflow communication pipeline 314 communicating with the reaction raw material pool is provided in the sedimentation tank 313, and the overflow communication pipeline 314 There is a one-way valve that flows from the sedimentation tank 313 to the reaction raw material pool 313. The downward inclined end of the step support platform 312 is located above the sedimentation tank 313. The reaction raw material pool is provided with NaOH solution, and the sedimentation tank is provided with Ca(OH) 2 Solution, other specific implementation methods are the same as in Example 1, and will not be repeated.

[0070] The specific working process of the sulfur removal device in this embodiment is as follows: the flue gas at the flue gas discharge area passes thro...

Embodiment 3

[0073] Embodiment three, see Figure 4 , Figure 23 , the difference between this embodiment and Embodiment 1 is: in this implementation, a certain number of front and rear rows of longitudinal beams with equivalent beam spacing are arranged between the step support platform 312 and the closed drainage cover 301, and one end of the front and rear rows of longitudinal beams It is fixed on the top of the kiln body, one end is connected to the closed drainage cover 301, and the front and rear rows of longitudinal beams are arranged in a staggered manner, and the filter screen is arranged between the adjacent front row of longitudinal beams 303-3 and the rear row of longitudinal beams 303-4 In between, a folded filter net is formed, and the mesh number of the folded filter net 303 is between 20-100, wherein there is only one row of vertical beams between the step support platform and the closed drainage hood, and the filter net 303 is fixed on the vertical beams to form Flat filt...

Abstract

The invention discloses various annular movable tile kiln flue gas dedusting and desulfurizing apparatuses. The principle of the apparatuses is characterized in that flue gas in a flue gas discharge zone goes through at least one filter screen under the drainage action of a closed drainage cover to filter out particulate foreign materials in the flue gas; and the flue gas filtered by the filter screen reacts with a NaOH solution sprayed by at least one row of nozzles under the drainage action of the closed drainage cover, a reacted gas is discharged to air under the action of an exhaust fan or an axial flow fan, a reacted mixed liquid flows to a regeneration pool provided with a Ca(OH)2 solution, a Na2SO3 solution and a NaHSO3 solution in the mixed liquid flowing to the regeneration pool further reacts with the Ca(OH)2 in the regeneration pool to afresh generate a NaOH solution, and the NaOH solution afresh generated in the regeneration pool is pumped to the nozzles through a water pump and undergoes a next reaction. The apparatuses have the advantages of good sulfur removal effect, reactant recycling and resource saving.

Description

technical field [0001] The invention relates to a dust removal and desulfurization device, in particular to a ring-type mobile brick kiln flue gas dust removal and desulfurization device and method. Background technique [0002] The biggest feature of the circular mobile kiln brick and tile kiln is that the brick body does not move while the kiln body moves in a rotating manner. The kiln body runs along a circular track and is divided into drying section, preheating section, roasting section and heat preservation section from front to back. , Cooling section, the total length is about l20m ~ 160m. The billet separating machine carried by the mobile trolley runs in the same direction as the kiln body, and the billets are stacked at the same time. The rotating and moving kiln body moves forward on the track at a speed of 70m / d~l20m / d, the front end "eats" the brick adobe, and the rear end "spits out" the finished brick, and completes drying-preheating-roasting-cooling- —The ...
