As preferably: described inlet mouth is arranged on tower body bottom, and ash discharging hole is arranged on bottom tower body, described purified gas outlet is arranged on tower body top; Described dry-process deacidification section is positioned at the top of dry method dust section.
As preferably: described dry-process deacidification section is made up of at least one adsorption stage, is filled with dry adsorption agent that is a kind of or two kinds of acidic substance in each adsorption stage.
As preferably: each described adsorption stage comprises the ventilation property supporting structure being arranged at inlet end and the Polygons division plate be erected in this ventilation property supporting structure, adsorption stage is separated into multiple air-flow combination passage by Polygons division plate, and described dry adsorption agent is arranged in this air-flow combination passage.
As preferably: the voidage of described ventilation property supporting structure is more than or equal to 40%, and minimum aperture size is less than the minimum diameter of dry adsorption agent.
As preferably: described dry adsorption agent is gac or the porous adsorbent containing basic activated component and catalyzer.
As preferably: described dry method dust section is provided with bag-type dust collector or dry method electrostatic precipitator.
As mentioned above, the beneficial effect of utility model is: with arrange separately the process program of extracting tower after dry method dust compared with, dry method dust section and dry-process deacidification section are arranged in same tower body, composition integral type blast furnace gas dry cleaner, collect dry method dust and dry-process deacidification purification function in a tower, namely occupation of land is saved, again can the acidic component such as dust and fluorine, chlorine, sulphur in cooperation-removal coal gas, reach the object of energy-saving and environmental protection.

Embodiment
The embodiment of utility model is described by particular specific embodiment below, and person skilled in the art scholar the content disclosed by this specification sheets can understand other advantages and effect of utility model easily.
Embodiment 1
As shown in Figure 1, the utility model provides a kind of blast furnace gas dry dusting depickling cleaner, comprise tower body 1, tower body 1 bottom is provided with inlet mouth 2, tower body 1 top arranges bottom purified gas outlet 5 and tower body 1 and arranges ash discharging hole 6, along Gas Flow to being disposed with dry method dust section 3 and dry-process deacidification section 4 in tower body 1, dry-process deacidification section 4 is arranged in the gas exit side of dry method dust section 3, and in this example, dry-process deacidification section 4 is positioned at the top of dry method dust section 3.
Dry-process deacidification section 4 is made up of at least one adsorption stage, dry adsorption agent 4c that is a kind of or two kinds of acidic substance is filled with in each adsorption stage, it is an adsorption stage in this example, this adsorption stage is by ventilation property supporting structure 4a, Polygons division plate 4b and dry adsorption agent 4c forms, ventilation property supporting structure 4a is positioned at the air inlet side of adsorption stage, it is the lower end of adsorption stage in this example, this ventilation property supporting structure 4a sets up multiple Polygons division plate 4b, thus form multiple polygonal air-flow combination passage, dry adsorption agent 4c is provided with in this air-flow combination passage, the voidage of ventilation property supporting structure 4a is not less than 40%, and minimum aperture size is less than dry adsorption agent 4c minimum diameter, prevent from sorbent material from coming off entering the dry method dust section 3 of bottom, and make air-flow enter adsorption layer after this current-sharing, dry adsorption agent 4c is gac or the porous adsorbent containing basic activated component and catalyzer, can slough the acidic component containing fluorine, chlorine, sulphur etc.Described dry method dust section 3 is provided with bag-type dust collector or dry method electrostatic precipitator.
During utility model works, the blast furnace gas of dust-laden and the gaseous acid such as chlorine, sulphur corrosion composition flows into tower body 1 through the inlet mouth 2 of blast furnace gas cleaner, after dry method dust section 3 removes dust, enter dry-process deacidification section 4 and remove gaseous acid corrosion composition, purified gas (dustiness≤5mg/Nm3 after dedusting depickling, gas condensed water PH=6 ~ 8), flow into purified gas pipe network via purified gas outlet 5.When blast furnace gas cleaner needs off-line maintenance, the valving on closedown inlet mouth 1 and purified gas export valving on 5.In cleaner, dust is regularly discharged outside tower through ash discharging hole 6.
