Thermal, realize that temperature equalization is distributed in heat storage, improves efficiency of utilization, increases the service life.
Technical scheme is as follows：
A kind of variable incubation cavity for flowing to formula solid heat storage device, including lower openings, incubation cavity inside set heat storage, accumulation of heat
Body bottom sets air water- to-water heat exchanger, and accumulation of heat body side surface sets wind deflector, and wind deflector is connected with blower fan.
Further, the described variable air channel for flowing to formula solid heat storage device, insertion being provided with inside heat storage.
Further, it is described it is variable flow to formula solid heat storage device, heat storage outer surface can be provided with netted frame
Frame, wind deflector are connected with grid framework.
Further, it is described it is variable flow to formula solid heat storage device, incubation cavity is the cavity surrounded by insulation material.
Further, it is described it is variable flow to formula solid heat storage device, blower fan can be frequency conversion fan.
Further, it is described it is variable flow to formula solid heat storage device, heat storage can be magnesia brick.
Further, it is described it is variable flow to formula solid heat storage device, the quantity of wind deflector is two, is oppositely arranged on storage
The both sides of hot body.
Further, it is described it is variable flow to formula solid heat storage device, thermal insulation board can be set below heat storage.
Further, it is described it is variable flow to formula solid heat storage device, thermal insulation board is vermiculite heat-insulating plate.
It is provided by the invention it is variable flow to formula solid heat storage device, by air water- to-water heat exchanger by thermal energy storage in heat storage
In, by controlling blower fan, change flow direction, allow wind to be alternately passed through from heat storage two sides so that heat storage interior temperature distribution is equal
It is even, improve energy storage stability.Meanwhile if blower fan air blast can also be divided into flow identical carried interest by the use of wind deflector so that
Temperature Distribution tends to be uniform to heat storage up and down.
The present invention converts electrical energy into storable heat energy by heat storage, using cheap electricity substituted peak ordinary telegram, reduces life
Produce cost.By transforming conventional solid accumulation of heat type, two blower fans set using accumulation of heat body side surface are replaced the present invention
Using progress Bidirectional variable-flow, while wind is shunted using wind deflector so that heat storage interior temperature distribution is uniform, not only subtracts
Each part heat fatigue loss is lacked, has increased the service life, while also improved efficiency of utilization, compared to current accumulation of heat machine
Type, overall performance and security, which have, to be greatly enhanced.
Brief description of the drawings
Fig. 1 is variable to flow to formula solid heat storage device schematic diagram described in the embodiment of the present invention 1；
Fig. 2 is variable to flow to formula solid heat storage device schematic diagram described in the embodiment of the present invention 2；
In figure 1 above and Fig. 2,1 is incubation cavity, and 2 be heat storage, and 3 be air water- to-water heat exchanger, and 4 be wind deflector, and 5 be blower fan, and 6 are
Thermal insulation board.
Embodiment：
The variable formula solid heat storage device that flows to provided by the invention is further described below in conjunction with accompanying drawing.
Embodiment 1
As shown in figure 1, formula solid heat storage device schematic diagram is flowed to for the variable of the present embodiment offer, including lower openings
Incubation cavity 1, the inside of incubation cavity 1 set heat storage 2, and the bottom of heat storage 2 sets air water- to-water heat exchanger 3, and the side of heat storage 2 sets and led
Aerofoil 4, wind deflector 4 are connected with blower fan 5.Wherein heat storage 2 is internally provided with the air channel of insertion, is easy in the aeration step of blower fan 5
Air-flow is circulated in air channel, and incubation cavity 1 is the cavity surrounded by insulation material, and insulation well can be played to heat storage 2 and is made
With reduction heat scatters and disappears.
The variable of the present embodiment offer flows to formula solid heat storage device in the process of running, can utilize night paddy electricity first
Energy storage is carried out, electric energy is converted into thermal energy storage in heat storage 2 by air water- to-water heat exchanger 3, make use of night honest and clean well
Valency paddy electricity, reduces production cost.Heat storage 2 after heat accumulation carries out air blast using blower fan 5 to it so that the heat in heat storage 2
Amount is evenly distributed, and wind-guiding is carried out in aeration step using wind deflector 4, realizes that the uniform heat of the whole different parts of heat storage 2 follows
Ring, and then heat accumulation is uniform and balances.
Embodiment 2
