Description
Technical field
It the utility model is related to thermal power plant ash cleaning technology field, and in particular to a kind of electric precipitation pneumatic ash removal system.
Background technology
Ash disposal system is the important component in power plant, and its energy-conservation produces a very large impact to station service power consumption rate, open at present
There is a kind of electric precipitation pneumatic ash removal system, its balanced valve all uses rotating balance valve, and such valve cell air-tightness is bad, most short
10 days cycles just occur dust stratification bite, it is necessary to disassembling overhaul, and in the winter time when, defeated grey unit intake valve and fluidized wind intake valve,
Valve element is freezed because under low temperature, there is moisture condensation, causes pneumatic operated valve to open and close failure, influences ash-transmission system normal operation.
The content of the invention
In order to solve the above-mentioned technical problem the utility model provides a kind of electric precipitation pneumatic ash removal system, in existing ash disposal system
Transformed on system, improve the air-tightness of balanced valve, also cause zero defect generation when whole ash disposal system is run in the winter time.
The technical solution of the utility model is：A kind of electric precipitation pneumatic ash removal system, including it is storehouse pump, ash bucket, outlet valve, flat
Weighing apparatus valve and intake valve, the balanced valve are dome balanced valve, are arranged on above the storehouse pump of ash disposal system, the intake valve both sides
Electrical heating heating tape is provided with pipeline, the heat tracing strip length is 1-2m.
Further, the intake valve includes fluidized wind intake valve and defeated grey unit intake valve to scheme.
The beneficial effects of the utility model are：The use of the utility model dome balanced valve, improves the airtight of balanced valve
Property, the use of electric-heating belt make condensate be not easy to condense in tube wall, valve, also improve the stabilization of air inlet fluidized wind system,
The expense of transformation is few, but remarkable in economical benefits, reduces personnel labor intensity, while reduces the branch of equipment maintenance cost
Go out, very big contribution is made that for unit safety economical operation.
