Abstract
The utility model relates to a revolution valve switching heat exchanger with multiple channels, which comprises heat storage bodies. A plurality of partition boards are fixed into a drum-shaped outer shell along radial direction and equally divide the drum-shaped outer shell into a plurality of fan-shaped channels, and the heat storage bodies are positioned in the fan-shaped channels; both ends of the drum-shaped outer shell are respectively provided with valve sheets having the same structure, and the valve sheets are fixed to a revolution shaft passing through the axial center of the drum-shaped outer shell and the immediate end heads of the partition boards; an end cover is arranged against the valve sheets and divided into an inner channel and an outer channel, and the valve sheets are respectively provided with a fan-shaped opening and a fan bar-shaped opening on the position corresponding to the inner channel and the outer channel of the end cover; a blind zone is formed between the two openings, and the blind zone can at least cover two axially symmetrical fan-shaped channels. The utility model omits a sealing device and a contaminant separation device and has compact structure and convenient use.
Description
A kind of multichannel rotary valve reversing heat exchanger relates to the direct contact heat switching equipment,
Chinese patent application has disclosed a kind of " regenerator ", the heat storage that it has a kind to have many runners, be used for carrying out heat exchange No. 85104275; The end face of heat storage has top cover, and it utilizes the radial seal liner that accumulation of heat is divided into not that being connected with puts hot gas and stops and heat absorption gas is stopped each part at least; These parts are because into suction, two kinds of gases of heat release are alternately led in constantly rotation relatively between heat storage and the top cover.Simultaneously, between the housing periphery of top cover and containing heat storage, sealing gasket is housed also.Though this heat exchanger has better seal and scale removal effect, but also exist following shortcoming: the physical dimension of top cover and heat storage, quality are all bigger, one of them realization is rotatablely moved, need bigger driving power and complicated supporting drive mechanism; There is relative motion between top cover and the heat storage, the sealing problem of its faying face is difficult to effective solution, and the faying face between top cover and the heat storage needs a rational gap, the suitable trouble of its adjustment, also dynamic need are imported into by the heat exchanger outside, and it is not too convenient to install, use.
At above-mentioned shortcoming, the purpose of this utility model provides a kind of multichannel rotary valve reversing heat exchanger, and it need not special hermetically-sealed construction and scale removal parts, thus compact conformation, with low cost.
Adopt such technical scheme according to above-mentioned purpose the utility model: it includes heat storage, it is characterized in that some dividing plates are fixed in the drum shape shell along directly asking, drum shape shell is divided into some sector channels, described heat storage is arranged in sector channel, drum shape shell two ends are separately installed with the identical valve block of structure, and valve block is fixed in the rotating shaft of passing drum shape shell axle center and abuts against clapboard end; End shield is installed near valve block and is divided into inside and outside two passages, and the position corresponding with the end shield internal and external channel has fan-shaped opening and fan strip shape gob on the valve block, be the blind area between described two openings, and the blind area can cover two sector channels of axial symmetry at least.
Because the utility model adopts rotary valve plate to realize the switching of different sector channels, thereby reaches the purpose of heat exchange, therefore need not special hermetically-sealed construction, and compact conformation, superior performance is with low cost, easy to use.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation according to the heat exchanger that the utility model proposes.
Fig. 2 is an A-A generalized section among Fig. 1.
Fig. 3 is the valve structure schematic diagram.
As shown in Figure 1, the two ends of barrel-shaped shell (6) are separately installed with valve block (4), thereby constitute Heat Room by barrel-shaped shell and valve block.Valve block (4) is fixed in the rotating shaft (2) of passing barrel-shaped shell axle center.Near valve block end shield (5) is installed, and end shield is divided into inside and outside two passages, so that hot and cold air passes through respectively.End shield (5) is fixed on the barrel-shaped shell (6) simultaneously.Be placed with heat storage (7) in the Heat Room, this heat storage and valve block preferably leave the gap between (4), so that air-flow evenly passes through heat storage.Heat storage then is fixed on the same motor of rotating shaft on the barrel-shaped shell (2) (1) by locating piece (8) and links to each other, and motor then is fixed in end shield (5) internal channel by support (3).Heat storage constitutes by woven wire is stacked, or is filled in the sector channel by metallic fiber
Referring to Fig. 2, barrel-shaped shell (6) is become some equal sector channels by radial dividing plate (9) radial separations, is placed with heat storage (7) in the sector channel again.The shape of heat storage preferably and the sector channel shape adapt.Valve block (9) is near clapboard end.And have fan-shaped opening and fan strip gab on the valve block.
The structure of valve block is referring to Fig. 3, the position that has internal channel on fan-shaped opening (12) and fan strip gab (10) and fan-shaped opening and the end shield on the valve block (4) is corresponding, the fan strip gab is corresponding with outer tunnel position on the end shield, is blind area (11) between fan strip gab and the fan-shaped opening.The size of blind area wants to cover two sector channels of axial symmetry at least.
When motor rotating band moving valve plate rotates, two valve blocks that are close on the sector channel rotate synchronously, fan-shaped opening has covered a part of sector channel separately with the fan strip gab, and is communicated with it, thereby has formed two endothermic gas passage and exothermal gas passages of isolating mutually.Simultaneously, the position of passage changes along with the variation of valve block upper shed position.Hot gas is blown into from the opening of appointment, under two valve block controls of slowly rotating, successively by each sector channel in the Heat Room, discharges surveying respective openings from another behind the heat transferred heat storage.Cold air is then from the other direction entering Heat Room, along with the rotation of valve block, in turn by each sector channel of Heat Room, absorbed the heat in the heat storage after, discharge from the corresponding opening of opposite side.Like this, two kinds of gases have been realized the exchange of heat by behind the heat exchanger.
