Abstract
A safety door steam exhausting device of high-pressure heaters and low-pressure heaters is characterized in that two perpendicular steam exhausting main pipes are arranged beside frame columns of a deoxygenizing chamber and a coal bunker chamber of a steam engine room, safety door steam exhausting pipes of the high-pressure heaters and the low-pressure heaters are respectively connected on the steam exhausting main pipes, steam is exhausted into the air from the upper ends of the steam exhausting main pipes, and the lower ends of the steam exhausting main pipes are connected with water drainage main pipes of a whole power plant, and accordingly, water in the heaters is prevented from being discharged into the air after safety doors of the high-pressure heaters and the low-pressure heaters are opened, and as a result, the power plant is damaged by freezing on the roof of the power plant in winter; the problem that steams are generated on the water drainage main pipes due to the fact that the steam is exhausted into the water drainage main pipes after the safety doors of the high-pressure heaters and the low-pressure heaters are opened, and safety running of a power plant is guaranteed; and working medium can be recovered, energy saving and emission reduction are realized, and running economic effect of the power plant is improved.
Description
Technical field
The utility model technology relates to the Fossil Fueled Power Plant Project construction field, especially relates to thermal power generation high-low pressure heater safety door blow-off line device.
Background technology
Conventional high-low pressure heater safety door blow-off line is directly discharged to atmosphere or the direct female pipe that discharges water that accesses.If high and low pressure heater safety door blow-off line is directly discharged to atmosphere, easily freeze at the factory building top winter, has potential safety hazard; If high-low pressure heater safety door blow-off line directly accesses female pipe that discharges water, steam enters female pipe that discharge water in the high-low pressure heater, and the on-the-spot female pipe that discharges water that exists emits the vapour problem, affects unit safety operation.
The utility model content
The purpose of this utility model provides a kind of high-low pressure heater safety door steam exhaust device, has both overcome the interior water of high-low pressure heater and has been discharged to atmosphere, the phenomenon of easily freezing at the factory building top winter; Solve again the interior steam of high-low pressure heater and enter female pipe that discharges water, cause the on-the-spot mother's pipe that discharges water that exists to emit in a large number the vapour problem.
For achieving the above object, the utility model provides a kind of high-low pressure heater safety door steam exhaust device, it is characterized in that: deaerator bay and the frame column next door of bunker bay in steam turbine building arrange two female pipes of vertical steam discharge, high-low pressure heater safety door gland steam exhauster is connected respectively on the female pipe of steam discharge, the female pipe of steam discharge upper end enters atmosphere, and the lower end connects full factory female pipe that discharges water.
The utility model is by being connected respectively to high-low pressure heater safety door gland steam exhauster on the female pipe of steam discharge, the female pipe of steam discharge upper end enters atmosphere, the lower end connects full factory female pipe that discharges water, therefore after can preventing that high-low pressure heater safety door from opening, water is discharged to atmosphere in the heater, especially avoid causing in the winter time the factory building roof to freeze, damage factory building by pressure; After having solved the unlatching of high-low pressure heater safety door, steam enters female pipe that discharges water, and female pipe that causes discharging water emits the vapour problem, guarantees safe operation of power plant; Can reclaim working medium, energy-saving and emission-reduction improve power plant's performance driving economy.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, high-pressure heater adopts biserial, i.e. A, B row.1 is No. 1 high-pressure heater A or B; 2 is No. 2 high-pressure heater A or B; 3 is No. 3 high-pressure heater A or B; 4 is No. 5 low-pressure heaters; 5 is No. 6 low-pressure heaters; The 6th, safety door; The 7th, the female pipe of steam discharge; The 8th, female pipe discharges water.
At the deaerator bay of steam turbine building and the frame column row next door of bunker bay the female pipe of two OD273 * 6.5 steam discharges is set, high-low pressure heater safety door gland steam exhauster is accessed respectively, the female pipe of steam discharge upper end row's atmosphere, the lower end drains into female pipe that discharges water.
