Description
[technical field]
The utility model belongs to fire (core) power plants generating electricity technical field, and the personnel relating to a kind of indirect dry cooling tower pass through door and pressure balance car, is specifically related to a kind of indirect cool tower car type two pass personnel and passes through door.
[background technology]
Huaneng Group Qinling Mountains in Shaanxi electricity generating corporation, Ltd extension project No. 7 machine indirect cool tower overall heights 179.8 meters, zero rice diameter 128.3 meters, " X " support column vertical height 27.8 meters, for Asia first high tower at that time, spreaded platform formed by ring flat-plate shape basis, X word post, tower cylinder and steel work, be " three tower unifications " engineering that Huaneng Group group company first integrates circulating water, smoke evacuation, desulfurization, capital construction cost is low, floor space is few, has stronger demonstration effect.
The personnel entering cooling tower pass through wicket, originally be designed to single track door, during enabling, effort is hard, from single track door leak into cold wind also affect the interchange of heat of indirect cool tower.Current wicket has just damaged after two months putting into operation, and has damaged very soon again, affect indirect cool tower and normally run after repairing and reinforcement.
[utility model content]
The utility model object is to overcome prior art defect, provides a kind of indirect cool tower car type two pass personnel to pass through door, the pressure differential that logical bridge case balance indirect cool tower is outside and inner, solves existing current door and is difficult to open, affects the problem that indirect cool tower normally runs.
For achieving the above object, the technical solution adopted in the utility model is:
Indirect cool tower car type two pass personnel pass through door, comprise external door, inside door and pressure self-balancing car; Car is communicated with inside and outside indirect cool tower, external door is provided with on external door snap close piece, inside door and is provided with inside door snap close and inside door rotation lock; Inside door is coated with rubber weather strip.
Further, described external door, inside door and car all adopt metal material to make.
Further, described inside door rotation lock is made up of Φ 20mm round steel.
Further, described external door and inside door all height be 2.1m, wide be 1.00m.
Further, described car height 2.1m, wide 1m, dark 2m.
Indirect cool tower car type two pass personnel of the present utility model pass through door, and comprise external door, inside door and pressure self-balancing car, external door, inside door and car form a pressure self-balancing passage jointly, and when external door is opened, inside door is in closed condition; Obtain when inside door is opened and close external door in advance, avoid leaking into a large amount of cold wind from current door, affect the interchange of heat of indirect cool tower, affect indirect cool tower and normally run.The utility model investment is low, manufacture is simple, flexible operation.
[accompanying drawing explanation]
Fig. 1 is that indirect cool tower personnel pass through the graph of a relation (from tower) of door and indirect cool tower
Fig. 2 be personnel pass through door with maintenance gate graph of a relation (from tower)
Fig. 3 opens figure (from tower) for the current door outdoors of personnel
Fig. 4 opens figure (from tower) for the personnel Men Neimen that passes through
[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1 ~ 4, indirect cool tower car type two pass personnel of the present utility model pass through parts that door comprises in table 1.
Table 1 figure elements instruction card
Indirect cool tower car type two pass personnel disclosed in the utility model pass through door, comprise tower external door 1, inside door 2 and car 3; External door 1, inside door 2 and car 3 all adopt metal material to make, and car 3 is communicated with inside and outside indirect cool tower, external door 1 are provided with on external door snap close piece 6, inside door 2 and are provided with inside door snap close 4 and inside door rotation lock 5; Inside door rotation lock 5 is made up of Φ 20mm round steel, and inside door 2 is coated with rubber weather strip.
External door external-open, is connected by sealing plate 10 between exterior door frame with cooling tower column-type radiator 11; Inside door 2 is opened outside car, and interior doorframe is connected with also sealing between car; External door 1 dead size is height × wide=2.1m × 1.00m, when inside door is closed, only uses F
lthe pulling force of=8N (≈ 0.8kg), just easily can pull open external door; Inside door dead size is height × wide=2.1m × 1.00m, when external door is closed, only uses the thrust of FT=8N, just easily can push inside door open; Bridge case dead size is high × wide × dark=2.1m × 1m × 2m.
In order to check the labor-saving effect of double-channel door.Do following test: when closedown external door, push inside door open, do not close inside door when just opening external door, the pulling force that external door is pulled open in actual measurement is F
l=903.8N (≈ 90.38kg).
The pass through operating process of door of indirect cool tower car type two pass personnel is:
(1) enter the flow process in tower: pull open external door, personnel enter bridge case and wait for → close external door, pressure self-balancing → push inside door → personnel open to walk out bridge case → closedown inside door.
(2) the outer flow process of tower is walked out: pull open inside door, personnel enter bridge case and wait for → close inside door, the good inside door of pressure self-balancing → snap close → push external door → personnel open to walk out bridge case → good external door of closedown external door → snap close.
(3) the good inside and outside door of snap close should be kept at ordinary times.
The principle of ship lock balance water level is transplanted and used for reference to the utility model, outside and the inner pressure difference value of compensation tower.
The utility model is on probation in the Qinling Mountains in Shaanxi electricity generating corporation, Ltd of Huaneng Group, achieves good effect.
Above content is further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the protection domain of the utility model by submitted to claims determination utility model.
