Description
Technical Field
The utility model relates to a prevent SDA semi-dry process desulfurization from putting device of dust raising between ash.
Background
The SDA semi-dry flue gas desulfurization technology is widely applied to sintering flue gas desulfurization technology. The principle is that sintering flue gas and atomized quicklime slurry are subjected to secondary contact reaction in a desulfurizing tower to remove SO in the flue gas2\SO3Capturing, wherein the reacted substances are discharged into the atmosphere along with the flue gas after dust collection and purification by a cloth bag, and the flue gas SO discharged into the atmosphere2The concentration is controlled below the national environmental protection standard, the standard emission is realized, and the environmental protection requirement is met.
In the desulfurization process, dust collected by a bag-type dust collector is discharged and loaded in a dust discharge room, and in the process, the dust in the dust discharge room is too large, so that the problems of environmental pollution and poor working environment of personnel are caused.
Disclosure of Invention
For overcoming the defects of the prior art, the utility model aims at providing a device for preventing the dust emission between the ash is put in the desulfurization of SDA semidry process, solving the problem that the dust emission is big between the ash is put in the desulfurization when putting ash loading in-process.
In order to achieve the above object, the utility model discloses a following technical scheme realizes:
the utility model provides a prevent that SDA semidry process desulfurization from putting device of dust raising between ash, be connected with the flue between desulfurizing tower and the dust remover, including dust cage, dust-leading flue, the person in charge that induced drafts, branch pipe, dust cage induced draft, dust-leading flue one end is connected with the flue, the other end with induced draft be responsible for and be connected, a plurality of branch pipes that induced draft with induced draft be responsible for and be connected, dust cage top and the branch connection that induced drafts, dust cage sets up and puts the ash point top, dust cage is under the narrow wide rectangular shape structure, and the bottom is uncovered, dust-leading flue on be equipped with the valve.
The dust-guiding flue is obliquely arranged, and the bottom end of the dust-guiding flue is connected with the main air-sucking pipe.
The number of the branch suction pipes is more than 3.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a dust remover put the inorganization raise dust problem between the ash. The dust collecting cover is adopted to collect the raised dust in the dust discharging and loading process, and the raised dust is sent into the dust remover for dust removal through the dust introducing flue, the purpose of improving the operation environment is realized by utilizing the existing equipment, the environmental protection is facilitated, and the improvement cost is low. The dust-guiding flue is obliquely arranged, so that raised dust can be directly conveyed to the dust remover, and a valve is arranged on the dust-guiding flue, so that the dust remover is only used in the dust placing and loading process, and the energy is saved. The dust collection cover adopts a strip-shaped structure, so that the dust collection cover is arranged above the dust discharge point when the tank car runs back and forth in the dust discharge loading truck.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.
See fig. 1-4, a prevent that SDA semidry process desulfurization from putting device of ash room raise dust, be connected with flue 2 between desulfurizing tower 1 and the dust remover 4, the booster fan at dust remover 4 rear portion provides suction for the flue, concrete structure includes dust cage 7, draw the dirt flue 3, the person in charge 5 induced drafts, branch pipe 6 induced drafts, dust cage 7, 3 one end of dust flue is connected with flue 2, the other end is connected with the person in charge 5 induced drafts, a plurality of branch pipes 6 induced drafts are connected with the person in charge 5 induced drafts, dust cage 7 top and branch pipe 6 induced drafts are connected, dust cage 7 sets up and is putting grey point top, dust cage 7 is the long bar-shaped structure wide under the upper limit, and the bottom is uncovered, the centre can set up the gusset, and high. And a valve 8 is arranged on the dust guiding flue 3.
Wherein, the dust-guiding flue 3 is obliquely arranged, and the bottom end is connected with the main air-sucking pipe 5. The number of the branch suction pipes 6 is more than 3.
Example (b):
in specific implementation, a circular hole with the diameter of 400mm is formed in the main flue 2 close to the dust remover 4, a dust collection cover 7 is arranged above a dust discharging point of the dust discharging room, and the distance between the dust collection cover 7 and the upper part of the tank car is 500 mm. Open 4 diameter 300mm round holes at dust collecting cover 7 top, connect a branch pipe 6 that induced drafts in every round hole department, four branch pipes 6 that induced draft gather one and induced draft and be responsible for 5, four branch pipes 6 that induced draft at the interval 1 meter between, rethread dust inducing flue 3 is connected to main flue 2, and is concrete, induced draft and be responsible for 5 and have valve 8 dust inducing flue 3 to be connected, and dust inducing flue 3 top is connected through diameter 400 mm's round hole with main flue 2.
