Abstract
The utility model discloses a turboset end cooling device, and belongs to the technical field of turbines. The turboset end cooling device comprises a turbine end shell, wherein a refrigerating pipeline is arranged between a turbine end shell and a turbine rotor; the two ends of the refrigerating pipeline extend out of the turbine end shell and are connected with an inlet pipe and an output pipe; the inlet pipe and the output pipe are communicated with a refrigerating tank filled with a refrigerant; the refrigerating tank is connected with a refrigerating unit. Steam in the turbine end shell is actively cooled into condensed water under the combined action of the refrigerating unit and the refrigerating pipeline, so that the cooling effect is good, the efficiency is high and impact of direct emission on the surrounding environment is reduced; condensed water obtained after the steam is cooled can be recycled, so that water resource is effectively saved; and the working power of the refrigerating unit is low, so that electricity is saved.
Description
Technical field
The utility model belongs to steam turbine technology field, relates in particular to a kind of steam turbine set end cooling unit.
Background technique
As everyone knows, steam turbine is very important machine in power plant, the steam producing from boiler need to be used the enterprise of vapour by steam turbine power generation or by steam supply, this part steam is steam turbine middle part and that higher part of pressure substantially, and the traditional way of the steam of steam turbine end is direct discharge, or drive the cooling water in cooling tower to circulate to eliminate by electric pump; The directly living environment around discharge meeting impact, and steam is all that water evaporates and comes, and directly discharges and can waste a large amount of water; Adopting electric pump to drive cooling water circulation, is that passive cooling aloft dispels the heat, and cooling-down effect is poor, and cooling efficiency is low, and needs to use high-power electric pump, causes electric power resource waste.
Model utility content
The purpose of this utility model is to provide a kind of steam turbine set end cooling unit, with steam that the steam turbine set end that provides of prior art is provided directly discharge or electric pump drive cooling water circulation, and cause water resources, electric power resource waste and cooling-down effect is poor, the inefficient problem of lowering the temperature.
For solving the problems of the technologies described above, the technical solution of the utility model is: steam turbine set end cooling unit, comprise steam turbine end housing, between described steam turbine end housing and the rotor of described steam turbine, be provided with refrigeration pipe, the two ends of described refrigeration pipe are all extended described steam turbine end housing and are connected with respectively supplying tube and output tube, described supplying tube and described output tube are all communicated with the refrigeration case that is loaded with refrigeration agent, and described refrigeration case is connected with cooling machine set.
Improve as one, described steam turbine end housing is provided with temperature sensitive member, and described temperature sensitive member is connected with described cooling machine set.
Improve as one, between described output tube and described refrigeration case, be provided with expansion joint.
As further improvement, described steam turbine end housing connects one for collecting the water tank of condensed water.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
Owing to being provided with refrigeration pipe in steam turbine end housing and being communicated with the refrigeration case being interconnected and cooling machine set, thereby by the acting in conjunction of cooling machine set and refrigeration pipe, steam in steam turbine end housing is carried out to active cooling down, make it become condensed water, good cooling effect, efficiency is high, reduce direct discharge to the impact of living environment around, the cooled condensed water of steam can also recycle simultaneously, effectively save water resources, and cooling machine set at work power is low, has saved electric power resource.
Because steam turbine end housing is provided with temperature sensitive member, this temperature sensitive member is communicated with cooling machine set, thereby respond to the temperature in steam turbine set end housing and signal is passed to cooling machine set by temperature sensitive member, accurately control the temperature in steam turbine set end housing, ensured normal work and cooling-down effect.
Because steam turbine end housing is communicated with a water tank, become centralized collection after Water in Condenser thereby steam is cooling, be convenient to recycle, further save water resources.
