Abstract
The utility model provides a thermal energy recovery heat exchanger which relates to a heat exchange component. The thermal energy recovery heat exchanger comprises a casing and a muffle pipe, wherein a cooling medium inlet and a cooling medium outlet are formed on the casing; the muffle pipe is arranged inside the casing; an outer air duct and an inner air duct are sequentially arranged between the casing and the muffle pipe; the outer air duct is communicated with the cooling medium inlet; and the inner air duct is communicated with the cooling medium outlet. Therefore, heat energy can be utilized again, and investment cost can be lowered effectively.
Description
Technical field
The utility model relates to a kind of heat-exchanging part, relates in particular to a kind of energy recovery heat exchanger.
Background technology
In steel plate hot dip at present, the continuous annealing production technology, steel band all must be heated to the recrystallization annealing temperature through heating furnace earlier, reduction furnace be heated to reduce about 750 ℃ surface film oxide, enter next procedure then and need lower the temperature again to handle and could satisfy technological requirement.Utilize recyclegas winding-up cooler (RJC) to cool and handle general with regard to current cooling, the method is that water is taken away heat, gives water for cooling with cooling tower again.
Prior art is with the mode that consumes energy heat to be discharged in the air, yet some workshop section also supplies with heat with the mode of consumes resources again on the production line, thereby can cause the waste of resource.
The utility model content
In order to address the above problem, the purpose of this utility model provides a kind of energy recovery heat exchanger, makes heat energy to be utilized once more, can effectively reduce investment and operation cost.
In order to achieve the above object, the utility model provides a kind of energy recovery heat exchanger, comprising:
One housing is provided with the outlet of the inlet and the cooling medium of cooling medium; And
One muffle tube is arranged in the described housing, and air channel and interior air channel outside being disposed with between described housing and described muffle tube, and wherein said outer air channel is connected with the inlet of described cooling medium, described in the air channel be connected with the outlet of described cooling medium.
Preferably, described interior air channel is combined by described muffle tube and described outer air channel.
Preferably, the material of described muffle tube is a stainless steel.
Preferably, described cooling medium is an air.
As shown from the above technical solution,, can make that heat energy utilizes once more, pollute, can effectively reduce cost of investment thereby reduce by this energy recovery heat exchanger.
Description of drawings
Fig. 1 is an energy recovery heat exchanger in the utility model.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment is clearer,, the utility model embodiment is done explanation in further detail below in conjunction with embodiment and accompanying drawing.At this, illustrative examples of the present utility model and explanation are used to explain the utility model, but not as to qualification of the present utility model.
As shown in Figure 1, be energy recovery heat exchanger of the present utility model, by among the figure as can be known, this energy recovery heat exchanger comprises: housing and muffle tube 3, its middle shell is provided with the outlet 2 of the inlet 5 and the cooling medium of cooling medium, and muffle tube 3 is arranged in this housing, and air channel 1 and interior air channel 4 outside being disposed with between this housing and muffle tube 3, and should be connected with the inlet 5 of cooling medium in outer air channel 1, air channel 4 is connected with the outlet 2 of cooling medium in this.
In the present embodiment, above-mentioned interior air channel is combined by described muffle tube 3 and described outer air channel 1, and the material of this muffle tube 3 is a stainless steel.By among the figure as can be known, the inlet 5 of this cooling medium and the outlet 2 of cooling medium can be arranged on the both sides of this energy recovery heat exchanger, certainly the position of this setting also is not limited to this.
In the present embodiment, the cooling medium that adopts in this energy recovery heat exchanger can be a gas cooling medium, or liquid cooling medium, is that example describes with gas cooling medium (for example air) only below, other cooling medium is similar in this, no longer applies at this and states.When adopting air, effectively reduce the complexity of this energy recovery heat exchanger structure, and can reduce the operating cost of energy recovery heat exchanger as the carrier of heat recovery.
Describe in the situation of steel part quenching, annealing and temper with this energy recovery heat exchanger applications below.
When high temperate zone steel passes the inside of muffle tube, this high temperate zone steel can conduct its heat to this muffle tube by heat radiation, make the temperature of this muffle tube raise, at first allow this moment cold wind spray to the outer wall of muffle tube by the inner chamber of cold air inlet through outer air channel, take away heat by of the outlet of interior air channel through heat exchange through cooling medium, lead to passivation oven dry bellows (workshop section that needs hot blast), and then the drying belt steel.
By this energy recovery heat exchanger being set between the reduction section of annealing furnace and strong cold section, and thermal energy exchange through the energy recovery heat exchanger, make heat can be used as the place that passivation oven dry etc. needs thermal source, shortened the length of leer like this, also reduced the quantity of recyclegas winding-up cooler, and saved the heat exchanger of passivation oven dry, also saved and aimed at a series of equipment and the personnel configurations such as boiler of passivation oven dry for steam.Make heat energy to utilize once more, effectively reduce and pollute, reduced cost of investment.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
