Degree of freedom, improves the economy of steam power plant.
Stable and economical operation of the heat-accumulator tank especially to back pressure unit with extraction-condensing steam turbine has important function, it
It is sufficiently used the heat supply of steam power plant.It stores heat energy cheap for steam power plant in heat-accumulator tank, in heat supply network peakload shape
Under state, heat-accumulator tank and steam power plant's combined heat, it is possible to decrease the heating load of high price spike thermal source, optimize the operation of system.
Heat-accumulator tank is the guarantee of heat supply network safe operation.When heating system water pump is out of service suddenly because of accidental cause,
Water attack will be produced, is made power plant internal and suffer very big destruction with heat distribution pipe network.If heating system is equipped with heat-accumulator tank, it will be big
Big destruction and the disaster that alleviates the high-voltage oscillation that water attack is caused, mitigate that water attack is caused.
Heat-accumulator tank is the standby heat source of heating system.When certain thermal source stops heat supply for some reason, heat-accumulator tank can be run in time
Complementary heating, prevents from causing big face to stop Warm status.
Existing accumulation of heat tank body is generally incubated using one layer of heat preservation structure, and the heat insulation effect of tank body is bad, and accumulation of heat is imitated
Rate is relatively low, easily causes thermal loss.
Content of the invention
The present invention is bad for solving existing accumulation of heat tank body heat insulation effect, and heat storage efficiency is relatively low, easily causes thermal loss
Problem, and then propose a kind of accumulation of heat tank body with multi-layer heat preserving room.
The present invention is adopted the technical scheme that for solving above-mentioned technical problem：The present invention includes inner housing, insulation flaggy, outer
Housing, lower shoe, concrete bed and base heat-insulation layer, shell body is sleeved on the outside of inner housing, inner housing and shell body it
Between be provided with insulation flaggy, the lower end of inner housing, insulation flaggy and shell body is respectively and fixedly connected on the upper surface of lower shoe, lower shoe
The upper end of concrete bed is arranged on, the lower end of concrete bed is provided with base heat-insulation layer, sets between insulation flaggy and shell body
There is the first soak chamber, between inner housing and insulation flaggy, be provided with the second soak chamber.
The invention has the beneficial effects as follows：
The present invention adopts three-decker in the tank body of heat-accumulator tank, with multi-layer heat preserving room, effectively prevents from carrying out inside and outside tank body
Heat exchange, heat storage efficiency height, high insulating effect, thermal loss can reduce more than 80%.
