Abstract
The utility model discloses a nuclear power plant changing room ventilating system. The nuclear power plant changing room ventilating system comprises a draught fan, the draught fan is arranged outside the wall body of a changing room, an air inlet of the draught fan penetrates through the wall body of the changing room through a first air pipe and is communicated with the changing room, a second air pipe is connected on an air outlet of the draught fan, and the draught fan is a box-type centrifugal fan. The nuclear power plant changing room ventilating system has the advantages that ventilating processing is conducted in the nuclear power plant changing room through the box-type centrifugal fan, and meanwhile the draught fan is arranged outside the changing room so as to radically eliminate direct noise sources in the room, effectively reduce noise levels in the nuclear power plant changing room, reduce risks of occupational hazards of staff, and promote management images of a nuclear power plant.
Description
[technical field]
The utility model relates to ventilating system, relates in particular to the ventilating system of a kind of nuclear power plant dressing cubicle.
[background technology]
The blower fan of a ventilating system of CPR1000 series PWR nuclear power plant is arranged in the cold dressing cubicle in radiation control zone, and what this class blower fan extensively adopted at present is axial flow blower, its flow be 9030 cubic metres per hour, fan pressure is 600 Pascals, make near the cold changing rooms blower fan noise level near 90 decibels, brought higher occupational hazards risk for the employee who in changing rooms, changes one's clothes, has a rest.
[summary of the invention]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and a kind of nuclear power plant's dressing cubicle ventilating system that can effectively reduce the room noise of changing one's clothes is provided.
The technical solution of the utility model is achieved in that a kind of nuclear power plant dressing cubicle ventilating system, it comprises a blower fan, described blower fan is arranged at outside the described dressing cubicle body of wall, the air inlet of described blower fan passes described dressing cubicle body of wall by first airduct and is communicated with described dressing cubicle, and the air outlet of described blower fan is connected with second airduct.
Below above-mentioned technical scheme is further set forth:
Described blower fan is box centrifugal blower.
Described first airduct is that the different round tubes of multistage diameter, conical pipe and/or rectangular tube connect to form.
The diameter of the end that described first airduct is connected with described air inlet is less than other end diameter.
Described second airduct is that the different round tubes of multistage diameter, conical pipe and/or rectangular tube connect to form.
The terminal gradual shrinkage body that reduces gradually for diameter of described second airduct.
The beneficial effects of the utility model are: one, the utility model adopt box centrifugal blower to the processing of ventilating in nuclear power plant's dressing cubicle, simultaneously, blower fan is arranged on the changing rooms outside, fundamentally eliminated direct noise source in this room, effectively reduce the noise level in the cold changing rooms of nuclear power plant, reduce employee's occupational hazards risk, promoted the manager's image of nuclear power plant; Two, first airduct and second airduct are designed to the different round tubes of multistage diameter, conical pipe and/or rectangular tube and connect to form structure, so, can reduce the noise of air-flow in the airduct.
[description of drawings]
Fig. 1 is structural representation Fig. 1 of the present utility model;
Fig. 2 is structural representation Fig. 2 of the present utility model;
Among the figure: blower fan 1; First airduct 2; Conical pipe 21; Second airduct 3; Gradual shrinkage body 31; Body of wall 4.
[specific embodiment]
The utility model will be further described below in conjunction with accompanying drawing and example.
Referring to figs. 1 through shown in Figure 2, nuclear power plant described in the utility model dressing cubicle ventilating system, it comprises a blower fan 1, described blower fan 1 is arranged at outside the described dressing cubicle body of wall 4, the air inlet of described blower fan 1 passes described dressing cubicle body of wall 4 by first airduct 2 and is communicated with described dressing cubicle, the air outlet of described blower fan 1 is connected with second airduct 3, because blower fan 1 is arranged on the changing rooms outside, fundamentally eliminated direct noise source in this room, effectively reduce the noise level in the cold changing rooms of nuclear power plant, reduce employee's occupational hazards risk, promoted the manager's image of nuclear power plant.
Further, described blower fan 1 is box centrifugal blower 1, can reduce blower fan 1 blast, blower fan 1 static pressure is adjusted into 450Pa, so, blower fan 1 noise can be worked as blower fan 1 from original 88dBa reduction noise to 65dBa(and connect first airduct 2 and second airduct 3 respectively into and out of the air port, the noise figure that records apart from blower fan 1 casing 1m place).
Further, described first airduct 2 connects to form for the different round tubes of multistage diameter, conical pipe 21 and/or rectangular tube; The diameter of the end that described first airduct 2 is connected with described blower fan 1 air inlet is less than other end diameter, and an end that is connected with blower fan 1 air inlet on first airduct 2 in the present embodiment is conical pipe 21.Described second airduct 3 connects to form for the different round tubes of multistage diameter, conical pipe 21 and/or rectangular tube; Described second airduct, the 3 terminal gradual shrinkage bodys 31 that reduce gradually for diameter so, can reduce the noise of air-flow in first airduct 2 and second airduct 3.
Described above only is preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, various distortion and modification can appear, and the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
