Abstract
The utility model provides a kind of back pressure turbine body drained water recovery system, the system includes body hydrophobic development unit, body drain recovery water tank, body drainage pump and vacuum dust cather, and shown body hydrophobic development unit is connected with body drain recovery water tank, body drainage pump and vacuum dust cather successively by pipeline.The utility model solves that back pressure turbine starts, the hydrophobic working medium of body existing for running wastes, " thermal pollution ", the problems such as disorderly row leaves about, both working medium and heat have been reclaimed, resource has been saved, has improved the economy of power plant, also caused obvious environmentally friendly social benefit.
Description
Technical field
Steam turbine field is the utility model is related to, more particularly, to a kind of back pressure turbine body drained water recovery system.
Background technology
In the heating project provided with back pressure turbine, as shown in figure 1, the characteristics of due to back pressure turbine itself,
Unit does not have condenser.Current most of power plant can all ignore back pressure turbine and start, caused hydrophobic time in running
Receipts problem, it is directly drained, not only cause the waste of working medium and heat, and thermal pollution can be produced, have influence on power plant's fortune
Row economy.
Utility model content
The purpose of this utility model is：A kind of the problem of existing for prior art, there is provided back pressure turbine body
Drained water recovery system, solution back pressure turbine starts, the hydrophobic working medium of body existing for running wastes, " thermal pollution ", unrest
The problems such as row leaves about.
Purpose of utility model of the present utility model is achieved through the following technical solutions：
A kind of back pressure turbine body drained water recovery system, it is characterised in that the system include body hydrophobic development unit,
Body drain recovery water tank, body drainage pump and vacuum dust cather, shown body hydrophobic development unit by pipeline successively with body
Drain recovery water tank, body drainage pump connect with vacuum dust cather.
Preferably, shut-off valve, the body drainage pump are provided between body drainage pump and body the drain recovery water tank
Shut-off valve, check-valves and shut-off valve are sequentially provided between vacuum dust cather.
Preferably, the body drainage pump includes body drainage pump A and body drainage pump B, the body drainage pump A and this
Shut-off valve is provided between body drain recovery water tank, shut-off valve is sequentially provided between the body drainage pump A and vacuum dust cather, is stopped
Return valve and shut-off valve；Shut-off valve, the body drainage pump B are provided between body drainage pump B and body the drain recovery water tank
Shut-off valve, check-valves and shut-off valve are sequentially provided between vacuum dust cather.
Compared with prior art, the utility model solves that back pressure turbine starts, body is dredged existing for running
The problems such as device of working medium waste, " thermal pollution ", random row leave about, has both reclaimed working medium and heat, has saved resource, improved the warp of power plant
Ji property, also caused obvious environmentally friendly social benefit.
Brief description of the drawings
Fig. 1 is conventional back pressures formula turbine proper water drain system connection diagram；
Fig. 2 is the connection diagram of the utility model back pressure turbine body drained water recovery system.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
The utility model is transformed on the basis of conventional system, innovated, and proposes that a kind of back pressure turbine body is dredged
Water reclamation system, carry out the recycling of working medium and waste heat.Shown in Figure 2, the system includes body hydrophobic development unit, body
Drain recovery water tank, body drainage pump and vacuum dust cather.Body hydrophobic development unit is a part of back pressure turbine.Very
Empty oxygen-eliminating device is the vacuum dust cather of waste heat boiler.Body hydrophobic development unit by pipeline successively with body drain recovery water tank,
Body drainage pump connects with vacuum dust cather.
After the utility model, in back pressure turbine running, by the hydrophobic entrance of body hydrophobic development unit
To body drain recovery water tank, return water tank controls its pondage by water level signal.Such as return water tank water level height, then this is opened
Body drainage pump, by the hydrophobic vacuum dust cather for squeezing into waste heat boiler, carry out the recovery of working medium and heat.
Embodiment 2
In the present embodiment, be provided with shut-off valve between body drainage pump and body drain recovery water tank, body drainage pump with it is true
Shut-off valve, check-valves and shut-off valve are sequentially provided between empty oxygen-eliminating device.These valves are used to carry out pipeline control and prevent water from returning
Stream.
The present embodiment remainder is consistent with embodiment 1.
Embodiment 3
In the present embodiment, body drainage pump includes body drainage pump A and body drainage pump B.Body drainage pump A and body
Shut-off valve is provided between drain recovery water tank, be sequentially provided between body drainage pump A and vacuum dust cather shut-off valve, check-valves and
Shut-off valve.Be provided with shut-off valve between body drainage pump B and body drain recovery water tank, body drainage pump B and vacuum dust cather it
Between be sequentially provided with shut-off valve, check-valves and shut-off valve.
Two body drainage pumps are set to play redundancy effect, can not be in use, then using another in a pipe passage
One pipe passage, and then avoid influenceing the operation of whole steam generator system.
The present embodiment remainder is consistent with embodiment 1.
Preferred embodiment of the present utility model is the foregoing is only, not to limit the utility model, should be referred to
Go out, all made within spirit of the present utility model and principle all any modification, equivalent and improvement etc., all should include
Within the scope of protection of the utility model.
