Abstract
The utility model relates to an aftertreatment factory air exhaust center fan equipment. Equipment includes: motor, guard flap, fan, motor hall, row fan room, fan shaft coupling, the fan is in row fan room, and in the orange district was arranged in to the pipeline of fan, motor hall and motor separated with guard flap between fan and the motor in arranging the white area in, it separates to establish the shielding partition wall between motor hall and the row fan room, adopt between fan and the motor the coupling joint. The utility model discloses can protect the motor room, make its inner space keep clean state, reduce ventilation blower especially maintenance, change risk and the degree of difficulty of motor by a wide margin, simultaneously, also can avoid dismantling the partition wall when overhauing the ventilation blower, the maintainer may not be worn the frog -suit and overhaul, reduces secondary pollution.
Description
Technical field
The utility model belongs to aeration technology field, is specifically related to reprocessing plant core ventilation wind devices field, for the core ventilation air draft center of nuclear fuel reprocessing plant.
Background technology
Reprocessing plant, is characterized in having comparatively high radioactivity.The main purpose of ventilating system is that the airborne radioactivity controlling working environment pollutes, the exposure of Occupationally Exposed to Radiation personnel and radionuclide soakage remained on the level of " safe and reasonable is feasible as far as possible low ", and to guarantee the safety limit being no more than national regulation.Air draft center is air draft and the detached building of discharge set by process tail gas of red, the orange district of each main factory building of concentrated emission aftertreatment factory and part Green Zone.Air draft center comprises air draft machine room, motor hall, pipeline enclosure, filtration cell, control room, exhaust chimney and the auxiliary room completed required for its function and auxiliary equipment.
In air draft Center Building thing, because conveying air dielectric contains radioactivity nuisance, all kinds of room must be arranged by subregion.In order to ensure operating personnel and Environmental security, design adopts multibarrier and four district's arrangement principle:
Staff enters white area work by door external separately.Enter Green Zone and have to pass through health gateway replacing work clothes.Health gate and air lock is all provided with, the alpha-contamination diffusion of strict control between Green Zone and orange district.Above color subregion belongs to common practise, sees GB18871-2002 " ionization radiation protection and the safe basic standard of radiation source ".
Utility model content
The purpose of this utility model is the defect for existing in prior art, provides a kind of safe, blower fan special arrangement method of running rational air draft center.
Between the orange district exhaust blower that the utility model provides, between wind turbine layout from general exhaust blower, wind turbine layout is different.Ventilation blower (containing motor) for red, the orange district air draft of former factory building is arranged in band radioactivity room, the drawback that service work difficulty is large, between the particularity of building, consider the factor such as operating personnel and Environmental security, air draft machine room, filtration cell and pipeline are placed in orange district, motor hall and auxiliary room are placed in white area, blower fan in ventilation blower and separating with guard screen between motor, and guard screen have employed different thickness according to the calculating of protection work post, for making installation and maintenance conveniently, take blower fan special arrangement method.
The Fan Equipment at reprocessing plant air draft center, described equipment comprises: motor, protective baffle plate, blower fan, motor hall, air draft machine room, fan coupler; Described blower fan is in air draft machine room, and the pipeline of blower fan is placed in orange district, and motor hall and motor are placed in white area, separate between blower fan and motor with protective baffle plate, establishes shielding partition wall to separate between described motor hall and air draft machine room; Described shaft coupling is adopted to be connected between blower fan with motor.
Further, the Fan Equipment at reprocessing plant air draft center as above, the thickness of described protective baffle plate is determined by the calculating of protecting work post.
Further, the Fan Equipment at reprocessing plant air draft center as above, the connection of described protective baffle plate and fan coupler seals.
The ventilation blower of red, orange district air draft and its necessary electromotor split at air draft machine room (orange district) and motor house (white area) by this method for arranging, and two rooms establish shielding partition wall to separate.Shaft coupling is adopted to be connected between blower fan with adapted motor, fan shaft place through walls, adopt protective baffle plate packing, by controlling the pressure reduction in fan house and motor house, ensure air flow direction and protective baffle plate double action, motor room can be protected, make its inner space keep clean state, significantly reduce ventilation blower especially motor maintenance, change risk and difficulty; Meanwhile, also can avoid dismantling partition wall during maintenance ventilation blower, maintainer can not wear frog-suit maintenance, reduces secondary pollution.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Fan Equipment at the utility model reprocessing plant air draft center.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
Attached Figure 1 shows that one safely, run rational a kind of blower fan special arrangement.Corresponding key equipment comprises: motor 1; Protective baffle plate 2; Blower fan 3; Motor hall 4 (white area); Air draft machine room 5 (orange district).
Blower fan is in air draft machine room 5, blower fan 3 pipeline is placed in orange district, motor hall 4 and motor 1 are placed in white area, separate with protective baffle plate 2 between blower fan and motor, and protective baffle plate 2, according to the thickness of the calculating decision plate of protection work post, protective baffle plate is connected will seals with fan coupler 6, motor hall 4 and air draft machine room 5 two regions ensure pressure reduction, for making personal security and maintenance conveniently, take blower fan special arrangement method.Ventilating system guarantees that air is from uncontamination district to contaminated area, and from low stain district to higher contaminated area, namely air-flow direction order is by white area to Green Zone, then arrives orange district, finally arrives red sector; Red sector air draft is compensated by orange district, and white area keeps barotropic state.
Meanwhile, the utility model can promote large-scale reprocessing plant integrated air exhaust central fan special arrangement, is thus used widely.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if belong within the scope of the utility model claim and equivalent technology thereof to these amendments of the present utility model and modification, then the utility model is also intended to comprise these change and modification.
