Abstract
The utility model relates to a cooling device for a plasma ignition system in the field of plasma ignition systems of a thermal power plant. According to the technical scheme, the cooling device for the plasma ignition system comprises two cooling water pumps connected in parallel, wherein cut-off valves are arranged at the two ends of each cooling water pump, and a check valve is arranged at one end of each cooling water pump. The cooling device for the plasma ignition system is characterized in that a third pipeline is in parallel connection with the two water pump pipelines connected in parallel and is provided with a cut-off valve and a check valve. The cooling device for the plasma ignition system has the advantages of lowering power generation cost, lowering station service power consumption rate and coal consumption of power supply, reducing energy consumption of a machine unit in the normal operation, and optimizes the operation mode. Through equipment modification, the plasma cooling water pumps are changed into a spare state from an operation state in the normal operation process, the plant power consumption is reduced, the plasma system is cooled through closed-type water pressure of 0.4 Mpa, the need for cooling water when the plasma cooling water pumps are in a spare state is met, and the need for resisting against coldness and freezing is met. When the machine unit is started, the cooling water pumps can be started rapidly, and the ignition requirement is met.
Description
Technical field
The utility model relates to a kind of plasma ignition system cooling device in the plasma ignition system field, thermal power plant.
Background technology
At present; most of newly-built units all adopt plasma ignition system to carry out unit starting and low-load combustion-stabilizing; plasma when operation temperature up to 4000 ℃; the main mode of cooling water+carrier wind that adopts is carried out cooling protection; cooling water system generally provides pressure by two cooling water pumps; plasma system mainly uses when unit starting; because the unit safety operation reliability improves now; the unit outage number of times descends; plasma ignition system is actual to utilize linearly downward trend of hourage, and the standby time prolongs, and must move a water pump during Daily Level Readiness; the waste power supply increases energy consumption.
The utility model content
The purpose of this utility model is exactly at existing situation, and a kind of energy-saving and cost-reducing and plasma ignition system cooling device simple in structure is provided.
Technical scheme: comprise two-way cooling water pump in parallel, the two ends of cooling water pump all arrange cut-off gate, the one end arranges non-return flap, it is characterized in that: at Third Road pipeline in the parallel connection again on the two-way cooling water pump pipeline of parallel connection, cut-off gate and non-return flap are set on the Third Road pipeline.
Beneficial effect
Reduce cost of electricity-generating, reduced station service power consumption rate and net coal consumption rate, reduced unit in normal operating energy resource consumption, optimize the method for operation, by scrap build, in service by operation transferred standby normal the plasma cooling water pump, reduce plant consumption, cool off by enclosed water pressure 0.4Mpa article on plasma system, both guaranteed when plasma is standby the needs of cooling water are satisfied protection against cold and freezing conditions requirement in winter again, when unit starting, can start cooling water pump rapidly, satisfy the igniting requirement.
Description of drawings
The specific embodiment
With reference to accompanying drawing 1, present embodiment mainly comprises two-way cooling water pump 1 in parallel, the two ends of cooling water pump 1 all arrange cut-off gate 3, the one end arranges non-return flap 2, at Third Road pipeline 4 in the parallel connection again on two-way cooling water pump 1 pipeline of parallel connection, cut-off gate and non-return flap are set on the Third Road pipeline 4, and a plasma cooling water pump rated power is 15MW, and back two the unit years of stopping transport are saved ten thousand yuan of expense 15 * 24 * 365 * 2 * 0.4469=11.74.
