Abstract
The utility model discloses a steam condenser, which comprises a condensing tank which is connected with a steam leakage port of a steam seal of a steam turbine, wherein the top end of the condensing tank is provided with a water pipe and is connected with a water storage tank; the upper part of the side wall of the condensing tank is connected with a vacuum pump through the water pipe; the vacuum pump is communicated with the water storage tank through a steam-water separator; and the bottom end of the condensing tank is communicated with the water storage tank through a self-priming pump. Steam which leaks at the steam seal of the steam turbine enters the condensing tank and flows from bottom to top in cooling water, condensed water rolls over from top to bottom, the pressure of the condensing tank is increased, pressure is reduced by using the vacuum pump, steam and liquid sucked out by the vacuum pump pass through the steam-liquid separator, the waste gas is discharged, and water is pumped into the water storage tank to store. The bottom end of the condensing end is provided with the self-priming pump, and condensed water in the condensing tank is pumped into the water storage tank to store, so that the steam is recycled. More advantageously, the vacuum degree of the steam turbine is also increased from 0.02 MPa before reconstruction to 0.06 MPa.
Description
Technical field
The utility model relates to a kind of condensation device of steam, more precisely, relates to a kind of condensing and recycling device of turbine steam seal exhaust.
Background technique
Steam turbine has stator and rotor two large divisions.Rotor high-speed rotation when work, stator is fixed, so must keep certain clearance between rotor and the stator, avoids its phase mutual friction.When vapor stream was crossed each level work of steam turbine, pressure, temperature descended step by step, existed pressure reduction in the dividing plate both sides, also existed pressure reduction before and after the moving vane.Steam flows through the acting from the passage of stator, movable vane except the overwhelming majority, and sub-fraction can flow through from various gaps and not do work, and becomes a kind of loss, has reduced the efficient of unit.Rotor also must pass cylinder, is supported on the bearing, also must leave the gap here.For the front end of high pressure cylinder two ends and intermediate cylinder, the vapor pressure in the cylinder will have steam to spill here greater than external atmospheric pressure, reduce unit efficiency, and cause the loss of part water of condensation., pass in the gap of cylinder because of the vapor pressure in the cylinder is lower than extraneous atmospheric pressure at the two ends of the exhaust end of intermediate pressure cylinder and low pressure (LP) cylinder, will have air to bleed in the cylinder at main shaft.Because air can not condense, thereby has reduced degree of vacuum, reduced steam acting ability in vapour condenser.In order to reduce the gas leakage in the above-mentioned gap everywhere; Guarantee the normal safe operation of steam turbine again, the spy is provided with the steam that various packings seal steam turbine, and a large amount of steam leakage can still be arranged; Existing way is to use the jetting stream vacuum method, causes every day about 6 tons steam to waste.Use the jetting stream vacuum method approximately to use 6 tons of steam in 24 hours, live steam loss 135*6=810 unit.
The model utility content
The utility model provides a kind of stram condenser in order to solve the problem that exists in the existing technology, can the steam of discharging from packing be recycled, and has avoided the waste of resource, has also practiced thrift electric energy simultaneously.
For realizing above-mentioned purpose; The technological scheme of the utility model is: a kind of stram condenser; Comprise the drainer that is connected with turbine steam seal gas leakage mouth, the drainer top is provided with water pipe and is connected with a water storage tank, and the top of drainer sidewall connects a vacuum pump through water pipe; Said vacuum pump is communicated with through a gas-liquid separator and water storage tank, and the bottom of said drainer is communicated with through a self-priming pump and water storage tank.
The beneficial effect of the utility model is that the steam that the turbine steam seal place spills enters into drainer, and is bottom-up in cooling water; Condensed water from up to down rolls; And the pressure of drainer is increased, and use vacuum pump to reduce pressure, the gas-liquid that vacuum pump is extracted out is through gas-liquid separator; Waste gas is discharged, and water then pump advances in the water storage tank to store.The self-priming pump that the bottom of drainer is provided with can advance the condensate pump in the drainer in the water storage tank to store, thereby accomplish the recycling with steam.Advantageously, also improved the degree of vacuum of steam turbine, risen to 0.06 MPa by 0.02 MPa before transforming.Use the condenser of the utility model, the power consumption cost is degree * 0.72=134.64 units every days 187, practices thrift cost 810-134.64=675.36 unit every day, and economic benefit is very considerable.
Description of drawings
Fig. 1 is the flow chart of the utility model vapor condensation apparatus.
Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
With reference to figure 1, the stram condenser of the utility model comprises the drainer 1 that is used for condensation process; The gas leakage mouth 8 of the below of its sidewall and turbine steam seal links together; Make the steam that spills from turbine steam seal enter into drainer 1, what the condensing and recycling of the utility model adopted is cooling water, so a water storage tank 6 is set; Through water pipe itself and the top of drainer 1 are connected together, the injection of cooling water adopts a circulating water pump 7 to get final product.The top of drainer 1 sidewall connects a vacuum pump 3 through water pipe, and said vacuum pump 3 is connected with water storage tank 6 through a gas-liquid separator.The steam that the turbine steam seal place spills enters into drainer 1; Bottom-up in cooling water, condensed water from up to down rolls, and the pressure of drainer is increased; Use vacuum pump 3 to reduce pressure; The gas-liquid that vacuum pump 3 is extracted out is discharged waste gas through gas-liquid separator 4, water then through water pump 5 again pump advance in the water storage tank 6 to store.The bottom of drainer 1 is provided with a self-priming pump 2, can the condensate pump in the drainer 1 advanced in the water storage tank 6 store, thereby accomplish the recycling with steam.Advantageously, also improved the degree of vacuum of steam turbine, risen to 0.06 MPa by 0.02 MPa before transforming.
Use the condenser of the utility model, the power consumption cost is degree * 0.72=134.64 units every days 187, practices thrift cost 810-134.64=675.36 unit every day, and economic benefit is very considerable.
Being merely the utility model preferred embodiment in sum, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to the technological category of the utility model.
