Abstract
The utility model discloses a system for recovering steam of a 12MW second-gear steam seal. The system comprises an exhaust trench pipeline for the 12MW second-gear steam seal, wherein a branched pipeline of a steam balance mother pipe, which is communicated to an deaerator, is led in front of a valve of the exhaust trench pipeline for the 12MW second-gear steam seal; and the branched pipeline is also provided with a valve before entering the steam balance mother pipe. According to the system disclosed by the utility model, the steam of the 12MW second-gear steam seal can be recycled and can be used for heating fed water and thermally deaerating, so that the temperature of the fed water is improved; meanwhile, the system is used for feeding water and deaerating, so that the exhausted steam is recycled; and in addition, noise pollution is also eliminated and the utilization rate of the steam is increased.
Description
Technical field
The utility model belongs to the steam turbine technology field, relates to a kind of vapor-recovery system, especially a kind of vapor-recovery system of 12MW two retaining packings.
Background technique
In the existing technology, the forward and backward two retaining packings of 12MW back pressure turbine are designed to arrange trench; The defective of row's trench has been to cause the loss of steam, will cause the back gland-packing leakage to increase if close, and is heavy losses to power plant's heat economic efficiency.
The model utility content
The purpose of the utility model is to overcome the shortcoming of above-mentioned existing technology, and a kind of vapor-recovery system of 12MW two retaining packings is provided, and noise pollution can be eliminated through the steam of 12MW two retaining packings is recycled by this system, improves the utilization ratio of steam.
The purpose of the utility model solves through following technological scheme:
The vapor-recovery system of this 12MW two retaining packings; The row's trench pipeline that comprises 12MW two retaining packings; Before the valve of row's trench pipeline of 12MW two retaining packings, draw one lead to the female pipe of vapour balance of atmospheric type oxygen-eliminating device lateral, this lateral also is equipped with a valve before getting into the female pipe of vapour balance.
On the above-mentioned lateral hydrophobic pipeline is installed.
The utility model is recycled the steam of 12MW two retaining packings, but heated feed water and be used for thermal de-aeration has not only improved the temperature of feedwater; Be used for feedwater deaeration simultaneously; Make steam discharge obtain recycling, also eliminated noise pollution simultaneously, improved the utilization ratio of steam.
Description of drawings
Fig. 1 is that the equipment of the utility model connects block diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
The vapor-recovery system of the 12MW two retaining packings of the utility model is as shown in Figure 1: it comprises row's trench pipeline of 12MW two retaining packings; Before the valve of row's trench pipeline of 12MW two retaining packings, draw one lead to the female pipe of vapour balance of atmospheric type oxygen-eliminating device lateral, this lateral also is equipped with a valve before getting into the female pipe of vapour balance.In order to prevent there is water of condensation in the pipeline, in the most preferred embodiment of the utility model, hydrophobic pipeline is installed on lateral also.
In sum, this recovery to the steam of 12MW two retaining packings of the utility model is transformed and has effectively been reduced because the noise pollution that two retaining gland sealing steam exhausts cause reduces the loss and the waste of steam simultaneously, has improved heat economic efficiency.
Claims (2)
1. the vapor-recovery system of a 12MW two retaining packings; The row's trench pipeline that comprises 12MW two retaining packings; It is characterized in that; Before the valve of row's trench pipeline of 12MW two retaining packings, draw one lead to the female pipe of vapour balance of atmospheric type oxygen-eliminating device lateral, this lateral also is equipped with a valve before getting into the female pipe of vapour balance.
