Abstract
The utility model discloses a drain recovery device for a steam turbine, and relates to the field of drain recovery utilization of steam turbines. The drain recovery device consists of a tank, an intake pipe and a recovered liquid output pipe, wherein a communicated spiral pipe is arranged in the sidewall and the top wall of the tank, and is communicated with the input end of a cooling water pipe on the lower part of the tank; nozzles are uniformly distributed on the inner side of the spiral pipe in the top wall of the tank; an aeration pipe coil is fixed on the inner middle part of the tank, and is communicated with the external intake pipe; a residual air discharging pipeline is arranged at the top of the tank, and is connected to the cooling water pipe through a steam condenser; the recovered liquid output pipe is arranged at the bottom of the tank. The drain recovery device for the steam turbine is novel in structural design; the cooling water spiral pipe is arranged in the wall of the tank, so that temperature in the tank is effectively reduced; the nozzles are arranged at the top, so that cooling water is ensured to fully contact with steam, the recovery efficiency of high-temperature steam is improved, good steam condensation effects are achieved, the recovery rate is increased, the production cost is lowered, and meanwhile, steam emissions are reduced to facilitate environmental protection.
Description
Technical field
The utility model relates to steam turbine drain recovery and utilizes field, relates in particular to a kind of steam turbine drainage recovering device.
Background technique
Steamer acting needs a large amount of steam, when doing work at Flows with in steam turbine, steam all can produce water of condensation, water of condensation is through chemically treated secondary demineralized water, its water producing cost is higher, if directly externally discharge can cause larger waste, drain recovery case plays the effect of water of condensation cycling and reutilization.There is certain defect in existing steam turbine drainage recovering device structural design, as: cause the hydrophobic water that do not condense into completely, in hydrophobic, contain a large amount of steam, steam condensation efficiency is not high, effect has good, cause the significant wastage of the energy, finally have to a large amount of steam to discharge, environment is affected.
Model utility content
The utility model is intended to for the deficiency existing in background technique, and a kind of steam turbine drainage recovering device is provided.
Steam turbine drainage recovering device of the present utility model, to be formed by tank body, suction tude and recovery liquid output tube, its tank body is built-in with the spiral coil of connection at sidewall and roof, spiral coil is communicated with cold water pipe input end at tank body lower part, uniform spout inside spiral coil in tank body roof, in tank body, middle part is fixed wtih aeration coil pipe and is communicated with outside suction tude, the top of tank body is provided with residual air and emits pipeline and be connected on cold water pipe by vapour condenser, and the bottom of tank body is provided with reclaims liquid output tube.
As further improvement of the utility model, described cold water pipe, residual air is emitted in pipeline, recovery liquid output tube and suction tude and is equipped with the pump housing and solenoid valve.
As further improvement of the utility model, described tank body top is provided with safety valve.
As further improvement of the utility model, the Way out on described aeration coil pipe down.
Steam turbine drainage recovering device of the present utility model; structural design novelty; by to cold water tray coil is installed in tank wall, effectively reduce the temperature of tank interior, top is provided with shower nozzle; ensure the abundant contact of cooling water and steam; improved the reuse efficiency to high-temperature steam, condensing gas is effective, has improved the recovery rate; and then having reduced the input of cost of production, the discharge that has simultaneously reduced steam is conducive to environmental protection.
Brief description of the drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
, be described further steam turbine drainage recovering device of the present utility model below in conjunction with accompanying drawing 1.
Embodiment 1
Steam turbine drainage recovering device of the present utility model, to be formed by tank body 1, suction tude 2 and recovery liquid output tube 3, be built-in with the spiral coil 4 of connection at sidewall and roof at tank body 1, spiral coil 4 is communicated with outside cold water pipe 5 input ends in tank body 1 bottom, spiral coil 4 inner sides in tank body 1 roof uniform spout 6, the interior middle part of tank body 1 is fixed wtih aeration coil pipe 7 and is communicated with outside suction tude 2, the top of tank body 1 is provided with residual air and emits pipeline 8 and be connected on cold water pipe 5 by vapour condenser 9, and the bottom of tank body 1 is provided with reclaims liquid output tube 3.The liquid of cold water pipe 5 is spilled in tank body 1 from spout 6 from tank body 1 bottom pumps into spiral coil 4, by aeration coil pipe 7 steam condensation out, because spiral coil 4 coils whole tank body 1, thereby the temperature of whole tank body 1 is relatively low, be conducive to condensing of steam inside by tank body 1 cold water pipe spout 6 and top own, the steam not condensing is emitted pipeline 8 by residual air and is entered and enter cold water pipe 5 after vapour condenser 9 and be back to tank body 1 inside, reclaims liquid output tube 3 liquid is re-entered in steam turbine and reused.
Embodiment 2
