Abstract
The utility model provides a take backup protection's fire to examine cooling air device, belongs to the thermal power auxiliary assembly field. The utility model aims at providing an it carries out refrigerated take backup protection's fire to examine cooling air device to the fiery probe of examining to be exclusively used in thermal power factory. The utility model discloses a main cooling blower and reserve cooling blower's tuber pipe compile behind the tuber pipe with main tuber pipe intercommunication, install the deflector apron in main cooling blower and reserve cooling blower's tuber pipe intersection, the intercommunication has and examines the zhi fengguan that the probe corresponds with the inside fire of boiler on main tuber pipe, the intercommunication has tuber pipe along separate routes on main tuber pipe, and internally mounted has the check valve at the shut tuber pipe to it connects manually operated door, the tuber pipe other end and cold one time wind channel intercommunication along separate routes to be provided with the wind channel on the shut tuber pipe. The utility model discloses simple structure, the design is novel. Being connected through examining the effective of cooling air with a wind with the fire, in security personnel's section steady operation, increasing by 6 kilovolts of operating voltage's reliable wind regime all the way in other words, it angers to have improved examines the operation factor of safety of probe, and the operation provides strong support to unit safety.
Description
Technical field
This utility model belongs to thermal power generation auxiliary equipment field.
Background technology
The most domestic also have many thermal power plants, its generating is using coal as primary raw material, in general boiler, flame detecting probe all can be installed, the highest yet with the temperature in boiler, flame detecting probe easily burns without cooling, existing Conventional solutions is to go out at flame detecting probe to be cooled down by cooling wind, but existing cooling air system often breaks down, and has a strong impact on normal production activity.
Summary of the invention
The purpose of this utility model is to provide a kind of fire inspection cooling wind apparatus being exclusively used in the band back-up protection that flame detecting probe is cooled down by thermal power plant.
Main cooling blower of the present utility model is pooled to after an airduct with the airduct of standby cooling blower connect with air main, airduct intersection at main cooling blower and standby cooling blower is provided with deflector apron, is communicated with the branch wind pipe corresponding with boiler internal flame detecting probe on air main;Being communicated with branch airduct on air main, have a non-return valve branch airduct is internally installed, and be provided with air channel on branch airduct and connect manually operated door, the branch airduct other end connects with a cold air channel.
This utility model simple in construction, novel.By effective connection the by First air with fire inspection cooling wind, be equivalent to, while security personnel's section stable operation, increase the reliable wind regime of the 6 kilovolts of running voltages in road, improve the operating safety factor of flame detecting probe, unit safety operation is provided and provides powerful support for.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Main cooling blower 1 of the present utility model connects with air main 4 after being pooled to an airduct with the airduct of standby cooling blower 2, airduct intersection at main cooling blower 1 and standby cooling blower 2 is provided with deflector apron 3, is communicated with the branch wind pipe 9 corresponding with boiler internal flame detecting probe on air main 4;Being communicated with branch airduct 8 on air main 4, have a non-return valve 6 branch airduct 8 is internally installed, and be provided with air channel on branch airduct 8 and connect manually operated door 7, branch airduct 8 other end connects with a cold air channel 5.
Main cooling blower 1 of the present utility model and standby cooling blower 2 constitute a-worker-a-backup, keep in repair when breaking down for one, and need another to be operated.When two blower fans of a-worker-a-backup switch over, in order to prevent work wind from shunting, it is mounted with deflector apron in Liang Ge airduct intersection, when which blower fan needs repairing, just with deflector apron, this blower ventilation pipe is closed.Depending on branch wind pipe 9 quantity on air main 4 is according to the flame detecting probe quantity of boiler internal, the air port of branch wind pipe 9 is just corresponding on flame detecting probe, thus cools down flame detecting probe.
The design principle of this utility model branch road airduct is:
1, it is connected on fire inspection cooling wind mother's pipe by the pipeline that cold First air pipeline welding one caliber is 350mm.
2, at the internally installed check baffle plate of caliber, wind can only be allowed to fire inspection cooling wind mother pipe from cold First air mother's pipe flow, do not allow the phenomenon that reverse flow occurs.
3, with fire inspection cooling wind mother's pipe centre position, one manually operated door is installed at check baffle plate, has isolating door during maintenance task as a cold wind regime.
4, in properly functioning, retaining a fire inspection cooling blower and run, open 7. number manually operated door, because the properly functioning blast of primary air fan is 11kPa, therefore wind is sent into fire inspection cooling wind mother's pipe from cold wind mother's pipe, just has two-way wind and cools down flame detecting probe.As fire inspection cooling blower mechanically or electrically part breaks down, cause blower fan to stop transport, then the cooling wind of flame detecting probe is all by cold First air mother's pipe tape splicing, it is to avoid probe burning phenomenon occur;As cold primary air duct carries out inspection operation, then 7. will close by number door, and by fire inspection cooling blower, flame detecting probe be cooled down completely, play the purpose of duplicate protection.
