Background technique
At present, be subject to the impact that the summer environment temperature is higher, Air-cooled Unit operation back pressure is all higher.The too high unit rated load that affects of back pressure in summer; Also affect stable operation of unit.There have been now a lot of Air-cooled Unit to adopt various technological means, to reduce the summer operation back pressure of Air-cooled Unit, guaranteed the nominal output of unit.In the large and medium-sized air cooling power plant of the north, common technological scheme is: for Air-Cooling Island, spike cooler in summer is set 1..When the summer environment temperature is higher, make the part steam turbine exhaust steam that will enter Air-Cooling Island originally enter the heat exchanger of a platform independent, by the auxiliary machine circulating cooling water system cools; 2. carry out spraying cooling by Yin Jie mono-road demineralized water to air cooling platform.Technique scheme all can reach the purpose of reduction or stable Air-cooled Unit back pressure, but two schemes all can not utilize the waste heat of steam turbine exhaust steam, and scheme two also needs to expend a large amount of demineralized waters, has increased operating cost.
The model utility content
The purpose of this utility model is to provide a kind of structure that can effectively utilize clammy unit and air cooling unit exhaust steam, to improve the unit whole efficiency.
For achieving the above object, the utility model adopts following technological scheme.A kind of mixed heating structure of clammy Air-cooled Unit water of condensation, it comprises Air-cooled Unit and clammy unit, this Air-cooled Unit comprises the air cooler low pressure (LP) cylinder, this air cooler low pressure (LP) cylinder connects the first exhaust steam discharge tube, this clammy unit comprises clammy unit low pressure (LP) cylinder, this clammy unit low pressure (LP) cylinder connects the second exhaust steam discharge tube, this the second exhaust steam discharge tube connects vapour condenser, this vapour condenser has condensate pipe, be connected with mixed heating system between this Air-cooled Unit and clammy unit, this Hybrid Heating system is connected with the first exhaust steam discharge tube and condensate pipe; This Hybrid Heating system comprises contact(-type) heater, and this contact(-type) heater has the first exhaust steam access tube and the second exhaust steam access tube, and this first exhaust steam access tube is connected with the first exhaust steam discharge tube, and this second exhaust steam access tube is connected with condensate pipe; This contact(-type) heater also is provided with the saturation water discharge tube, and this saturation water discharge tube is connected with clammy unit with Air-cooled Unit respectively.
Be provided with the water of condensation shifting pump on the second exhaust steam access tube.
The beneficial effects of the utility model are as follows.
The characteristics of utilizing some big power station to have two kinds of main frame types of cooling concurrently (are that Air-cooled Unit had both been installed by power plant, clammy unit has been installed again), the exhaust steam of Air-cooled Unit is heated to the water of condensation of clammy unit, also reduced the back pressure of Air-cooled Unit when improving clammy unit condensing water temperature, this has solved the defect that on current conventional Air-cooled Unit, after increase back pressure control device, the exhaust steam in steam turbine waste heat is not used.After adopting this technology, unit can therefrom benefit the whole year: the one, improved the condensing water temperature of clammy unit, and reduce low-pressure pumping steam, increase the unit generation amount; The 2nd, reduced the operation back pressure of Air-cooled Unit, can improve generatine set heat efficiency.
