Description
Technical Field
The utility model belongs to the technical field of thermal power, a thermal power denitration drainage system is related to.
Background
In a thermal power generation system, an SCR denitration system needs to be continuously put into operation, wherein a hydrolyzer in the SCR denitration system can normally work under the condition that the rated steam pressure is required to be maintained at 0.5-0.55 MPa and the rated temperature is required to be maintained at 135-150 ℃, a heating steam source is condensed into hydrophobic water after passing through a coil pipe in the hydrolyzer when a unit normally operates, and the hydrophobic water is drained to a denitration hydrophobic box through a hydrophobic pipeline and a valve; in addition, rotation air preheater among the SCR deNOx systems need carry out steam when the operation and blow the ash to need carry out the pipeline hydrophobic before blowing the ash, hydrophobic dredging to denitration drain tank through drain pipe and valve, do not accomplish recycle, based on this, the utility model provides a thermal power denitration drainage system to solve the above-mentioned hydrophobic unable recycle's problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to the problem that prior art exists, provide a thermal power denitration drainage system, solved in thermal power system that the pipeline is hydrophobic can't be by abundant recycle, lead to the wasting of resources's problem.
Therefore, the utility model adopts the following technical proposal:
the utility model provides a thermal power denitration drainage system, includes the denitration drain box, the denitration drain box is equipped with first water inlet, second water inlet, first delivery port and second delivery port, first water inlet, second water inlet pass through the governing valve and are connected with hydrolysising ware, soot blower, first delivery port passes through the drainage pump and is connected with three way connection, three way connection is connected with the hydrophobic flash tank of steam turbine oxygen-eliminating device, steam turbine body and blow off pipe respectively, and the hydrophobic flash tank of steam turbine oxygen-eliminating device, steam turbine body is parallel connection.
Furthermore, regulating valves are arranged among the steam turbine deaerator, the steam turbine body drainage flash tank and the three-way joint.
Furthermore, the second water outlet is connected with the sampling container, and an adjusting valve is arranged between the second water outlet and the sampling container.
The beneficial effects of the utility model reside in that:
the utility model discloses through installing equipment such as hydrophobic pipeline, governing valve and flash tank additional, solved hydrophobic crowded problem of arranging, final hydrophobic dredging will obtain recycle when the qualified hydrophobic of hydrophobic quality to the hydrophobic flash tank of steam turbine side body or steam turbine oxygen-eliminating device after the unit starts, has improved unit operation economy.

Detailed Description
The technical solution of the present invention will be described below with reference to the accompanying drawings and implementation methods.
As shown in fig. 1, a thermal power denitration steam trap system includes a denitration steam trap 1, the denitration steam trap 1 is provided with a first water inlet 1a, a second water inlet 1b, a first water outlet 1c and a second water outlet 1d, the first water inlet 1a and the second water inlet 1b are connected with a hydrolyzer 3 and a soot blower 4 through a regulating valve 2, the first water outlet 1c is connected with a three-way joint 6 through a steam trap 5, the three-way joint 6 is respectively connected with a steam turbine deaerator 7, a steam turbine body drain flash tank 8 and a blow-off pipe 9, and the steam turbine deaerator 7 and the steam turbine body drain flash tank 8 are connected in parallel; in addition, the second water outlet 1d is connected with the sampling container 10, and a regulating valve 2 is arranged between the second water outlet and the sampling container.
Furthermore, regulating valves 2 are arranged among the steam turbine deaerator 7, the steam turbine body drainage flash tank 8 and the three-way joint 6.
When the unit normally operates, the heating steam condenses to hydrophobic behind the coil pipe in the hydrolyzer 3, hydrophobic flows into denitration drain box 1 through pipeline and governing valve 2, and simultaneously, 4 operation of soot blowers will carry out the pipeline hydrophobic before, hydrophobic flows into denitration drain box 1 through pipeline and governing valve 2, detect hydrophobic quality through sampling container 10, when hydrophobic quality is qualified, hydrophobic will flow to steam turbine oxygen-eliminating device 7 or 8 recycle of hydrophobic flash tank of steam turbine side body, when hydrophobic quality is unqualified with it through blow off pipe 9 discharges can.
In the actual operation process, the utility model discloses a hydrophobic recycle, according to every machine consumption 12 tons steam every day, two machines are according to 6 months every year to calculate, and the system consumes steam 4320 tons all the year, and every ton demineralized water 20 yuan can practice thrift 8.6 ten thousand, can save the cost of electricity generation effectively, suitable popularization.
