An autothermal-type heat exchanger where larger heat transmission area is achievable in spite of a limited capacity, relatively easy to produce, and provides vast improvement in heat exchange efficiency. A heat exchanger having a partition wall-type heat transmission body (BF) for partitioning a high temperature fluid (1) and a low temperature fluid (2) is characterized as follows. The heat transmission body (BF) has a bellows shape and formed such that both fluids (1, 2) flow in gaps in the bellows portion of the heat transmission body (BF) in the directions opposed to each other along ridge lines or valley lines of the bellows portion. At one end or both ends of the heat transmission body (BF) at which one end or both ends the ridge lines of the bellows portion intersect, there is provided a flow-around space portion(s) (F) for causing one of the fluids to flow around into the gaps of the bellows portion on the opposite side. Heat is exchanged such that one of the fluids that flow around into the opposite side through the flow-around portion(s) (F) becomes the other fluid whose heat is to be exchanged.

Description

Technical description Heat exchanger and reactor and radiation heater using the same

The present invention relates to a heat exchanger, a reactor using the heat exchanger, and radiation heat, and is particularly applied to the field of thermal engineering for saving energy consumption and the environmental technology field for the purpose of purifying exhaust gas from the atmosphere. And a suitable technique. Background art

As one of the methods for improving the performance of the bulkhead heat exchanger, many attempts have been made to increase the area of the heat transfer body (partition) as much as possible within the limited space capacity. Making the shape of the heat transfer body bellows is a typical method. Another way to improve performance is to align the flow directions of the two fluids so that they flow in the same direction across the heat transfer surface, or in opposite directions. In order to realize such a flow, heat exchangers such as a multi-tubular cylindrical structure, a plate structure in which a large number of press-formed heat transfer plates are stacked, and a spiral type have been made.

On the other hand, if heat is exchanged between upstream and downstream for one fluid, the temperature can be changed only in a part of the flow without consuming excessive heat energy, and various chemical reactions and Thermal energy loss in the heat treatment process can be reduced. Furthermore, a system that uses a self-heat exchanger with a spiral structure as an integration of such a self-heat exchanger and catalyst or burner combustion (Reference: 39th Combustion Symposium, Publication Number C 1 4 5 , 1 January 1 1-1 January 2 3, 1991, Yokohama, and a method using a rotary heat storage type heat exchanger (“50% reduction in fuel consumption, energy environment design gas burner”) Nikkei Sangyo, see June 25, Heisei 14).)

(First example)

FIG. 1 shows a three-dimensional perspective view of a heat exchanger according to a first embodiment of the present invention.

The heat exchanger of this example has a bellows type heat transfer body (BF). This bellows type heat transfer body (BF) has a bellows type (bellows type or accordion type) structure that separates the high temperature fluid 1 from the low temperature fluid 2 or 2. Both end faces (A and Α ') intersecting the ridgeline of the bellows portion of the bellows type heat transfer body (BF) are sealed by closely contacting the upper and lower walls of the heat exchanger via a sealing material (not shown). Has been. In addition, both ends (a and a ') of the heat transfer body (BF) parallel to the ridgeline of the bellows portion are welded or sealed (not shown) with the side walls (C, C) constituting both sides of the heat exchanger. It is sealed by bringing it into close contact with each other. In addition, for the front and rear side faces (B and Β ') of the heat exchanger facing the ridge line of the heat transfer body (BF), the distance between the ridge line part of the heat transfer body (BF) and the side face of the container (Β and Β') is bellows. The two fluid outlets (D, D ', Ε, Ε') are front and back sides (前後 and Β ') relative to the ridge spring of the heat transfer body (BF). It is provided near both upper and lower ends.

By adopting the structure as described above, two fluids entering at the front and back entrances with different temperatures are separated from each other by the bellows type heat transfer body (BF) and the gaps in the direction of the bellows ridgeline. Cocurrent (flow 1 and 2) or countercurrent (1 and 2,) can be realized. In addition, by using a bellows type heat transfer body, a large heat transfer area can be obtained within a limited capacity. In addition, the bellows type heat transfer body is relatively easy to manufacture, and the heat exchange efficiency is dramatically improved.

Although the triangular wave shape is exemplified here as the cross-sectional shape of the heat transfer body (BF), the shape is not limited to this, and the wave shape or a flat plate shape in which only the ridge portion is semicircular may be used. In addition, the heat transfer body (BF) may be formed by bending a foil-like stainless steel or by firing a plate-shaped ceramic material before firing into a bellows shape. Also, As a method to prevent damage and deformation of the bellows type heat transfer body due to external compressive force, the foil-like stainless steel or the plate-like ceramic surface before firing is made uneven or the corrugated plate is perpendicular to the ridgeline of the wave Alternatively, it may be bent in a non-parallel direction to form a bellows type so that adjacent bellow surfaces touch each other.

FIG. 2 (a) is a front perspective view of the structure shown in FIG. D and E are the same fluid 1 entrance as Fig.1. On the back side of each, there are entrances D 'and Ε' for fluid 2. B and b 'are the ridge and valley lines of the bellows type heat transfer body (BF) as seen from the front. The overall shape of the bellows-type heat transfer body (BF) is not limited to the rectangular parallelepiped as shown here. For example, as shown in Fig. 2 (b), the fluid inflow / outflow part is expanded like a fan. The distribution resistance of this part may be reduced. Further, as shown in FIG. 2 (c), the entire bellows type heat transfer body may be a fan type. By doing so, the flow velocity of the fluid can be changed along the flow, and in some cases, more efficient heat exchange can be achieved.

Furthermore, the configuration shown in FIG. 3 may be formed by making the shape of FIG. 2 (c) round in the circumferential direction. In this case, the end portions of the heat transfer body (BF) parallel to the ridge line are sealed by means such as welding to each other or using a sealing material. The symbols in Fig. 3 indicate the parts corresponding to Fig. 1. D, E, D ', and E' are the inlets and outlets of fluids 1 and 2 (2 '), respectively, as shown in Fig. 1. By changing the direction of fluid 2, countercurrent flow (2) is also countercurrent. (2 ') In this structure, it is necessary to seal outside the cylinder surface A, A ^5. However, by adopting such a cylindrical shape, both ends (a and a 'in Fig. 1) parallel to the ridgeline of the bellows disappear. For surfaces B and B ', as in Fig. 1, the distance between the heat transfer (BF) ridge and the side of the container need only be sufficiently smaller than the bellows pitch, and sealing is not necessary.

Although it is also cylindrical, a structure in which bellows type heat transfer bodies are arranged as shown in Fig. 4 is also possible. Each symbol in FIG. 4 also indicates each part corresponding to FIG. In this case, the heat transfer body (BF) is placed in a space between the outer cylinder B and the inner cylinder B ′. At the end faces (A and Α ') perpendicular to the ridge line of the heat transfer body (BF), Seal with heat (BF) by means such as close contact with sealant. In addition, it is necessary to seal both ends parallel to the ridge line of the heat transfer body (BF) so that the fluid does not leak to the opposite surface of the heat transfer body (BF) by completely contacting each other or welding. However, as in the case of the structure shown in Fig. 3, the seal with the container wall disappears at this point, making it unnecessary. On the other hand, on the B and B 'faces, as in Fig. 1, the distance between the ridgeline of the heat transfer element (BF) and each face should be sufficiently smaller than the pitch of the bellows on each face. There is no.

(Second embodiment)

FIG. 5 shows a heat exchanger according to the second embodiment of the present invention. The heat exchanger of the present embodiment is a two-fluid bulkhead heat exchanger having the structure shown in FIG. 1, and a pair of fluid inlets / outlets (D) on opposite sides of the bellows type heat transfer body (BF) (D , D ', Ε, Ε') instead of D as the inlet, D 'as the outlet, and one end (A ⁵ ) of the heat transfer body (BF) is not tightly sealed, but the inlet (D ) Is provided with a fluid wrap-around space (F) for wrapping the fluid entering from the heat transfer body (BF) to the opposite side. The other configuration is the same as that of the first embodiment.

By adopting such a structure, it becomes a self-heat exchange type heat exchanger in which one fluid flows counter-currently between the upstream and downstream sides of the bellows type heat transfer body (BF). In addition, by applying the same modification, any of the heat exchangers shown in FIGS. 2, 3 and 4 can be a corresponding self-heat exchanger.

In addition to the effects of the first embodiment, the heat exchanger of this embodiment seals pipes and fluids compared to a self-heat exchanger that uses a conventional heat exchanger structure represented by a multi-tube cylindrical type. The structure is greatly simplified, and even if the number of bellows is increased, the whole and seal structure are not complicated at all, and a self-heat exchanger with extremely high heat exchange efficiency can be obtained. .

Fig. 6 (a) is a front perspective view of the structure of the self-heat exchanger of Fig. 5. In the figure, b is the ridgeline, and b 'is the valley line (corresponding to the ridgeline of the opposite bellows).

In the second embodiment, the fluid wraparound space (F) where the temperature is an extreme value must be present. However, as shown in Fig. 6 (b), the fluid inlet / outlet (D, D ⁵ ) is provided in the center of the ridge line direction of the heat transfer body (BF), as shown in Fig. 6 (b). The fluid flowing in from the flow branches in the vertical direction, circulates in the spaces (F, F ') adjacent to the different end faces of the heat transfer body (BF), then merges and exits from the outlet (D') You can do it. By doing so, the seal between the heat transfer body (BF) and the container 'b on the surface (A) becomes unnecessary.

Furthermore, Fig. 6 (c) shows a bellows-type heat transfer body (BF) along the ridgeline direction for a self-heat exchanger with an inlet / outlet in the center as shown in Fig. 6 (b) and where fluid flows. The overall shape of the long rectangular parallelepiped is made into an annular shape, and both ends of the heat transfer body (BF) intersecting with the ridge line share the same fluid wraparound space (F). This modification has the advantage of eliminating the need for a seal at the end face of the bellows portion while making the space (F) where the temperature is an extreme value one place.

(Third example)

Hereinafter, a reactor based on the self-heat exchanger having the structure shown in FIG. 5 will be described. The reactor shown in Fig. 7 is based on the self-heat exchanger shown in Fig. 5, and has a heating element (Hitoshi) or endothermic element (G) in the fluid wrapping space (F). This reactor is integrated with the heat exchanger. In a reactor having such a structure, heat is transferred between an inflow fluid having a low temperature (high) and an effluent fluid heated (cooled) through a space (F) having a maximum (minimum) temperature. The temperature at the outlet (D ') with respect to the entrance (D) does not become so high (eg, low) even if the space (F) becomes very hot (low temperature), the temperature at F, D, etc. (20 ° C, 700 ° C, 90 ° C, respectively) o With such a structure, it is necessary to heat the fluid to react with it. Therefore, it can be used as a reactor that can reduce energy (electric power). Therefore, it can be expected to be applied to chemical reaction equipment in general.

Theoretical estimation of the performance of the third embodiment:

The performance of the self-heat exchange reactor of the third embodiment shown in Fig. 6 is roughly estimated. The If the bent shape of the bellows-shaped ridgeline (or valley) of the heat transfer body (BF) is semicircular and the heat transfer surfaces are parallel to each other, the heat conduction in this case sandwiches the parallel plates. It can be regarded as heat conduction between different fluids. The total area of the bellows surface is A (m ² ), the heat transfer rate from the high temperature fluid to the low temperature fluid across this heat transfer surface is K (W / m ² K), and the distance between adjacent bellow surfaces is d ( m). When the surface separation is d = 10.− ³ (= 1 mm), it is expected that the flow in the reactor will be laminar when the flow velocity of the fluid is on the order of 1 m / s. In laminar flow flowing between parallel plates, the heat transfer rate h (W / m ² · K) between the wall surface and each of the high-temperature and low-temperature fluids is the condition that the heat flux is constant (the countercurrent self-heat exchange reactor is Under this condition)

h = 140/17 χ λ / D

Given in. Here, the coefficient 140Z17 is a dimensionless number usually called a Nu s se 1 t number, and is a value determined analytically under given conditions. Is the thermal conductivity of the fluid (W / m. K), D is the dimension called the representative length.

It is. Also,

It becomes. In Fig. 7, assuming that a heating element is used, let Q (W) be the calorific value, and the heat capacity flow rate of the fluid (assuming no temperature dependence) 〃 C _P (J / K • s) and the heat exchanger is ideally insulated and has no heat dissipation except exhaust heat.

Also, the fluid temperature T _ri flowing into the fluid wrap-around section (F) and the fluid temperature T _r flowing out of the fluid wrap-around section (F). Between

Τ _Γ0 — T _ri = Q / (u _P ) Holds. Here, the heat exchange rate, which means how much heat is transferred from the hot fluid to the cold fluid,

Using the equation (1), a rectangular thin plate with a length of 1600 mm and a width of 200 mm (i.e., A = 0.32 m ² ) is bent into 40 planes at intervals of 40 mm, and the interval between adjacent planes is lmm (= d ) And 20 ° C air (density p = 1. 1 6 6 kg / m \ constant pressure specific heat C _P = 100 5 J / kg · K), heat The relationship between the air flow velocity V (L / s) and the heat exchange rate ø when the operating condition of the exchanger is assumed to be constant around 20 ° C (= 0.02 5 7W / m The results are shown in Table 1. In this case,

Calculated as

3 82.8 A (m ² ) = 0.32 The volume V of this heat exchanger formed into a bellows shape is only about 0.32 L. Therefore, the space velocity when v = 1 LZs is 3 6 00 v / V = 1 12 50 h− ¹ . Even at such high space velocities, if the heat transfer body (BF) can be bent completely into a parallel plate as assumed in the calculation, the heat exchange rate of 93.5% is extremely high. It is expected to demonstrate. Similarly, even at higher space velocities of v = 2 L / s (SV = 2 2 500 h—, 3 L / s (SV = 3 3 75 0 h ¹ )), 87.8% and 82.8 respectively. A high heat exchange rate of% is obtained.

Performance verification experiment of the third embodiment:

Next, Table 2 shows the results of a prototype of the reactor with the same dimensions as the calculation example above (No. 1) and its performance. Stainless steel foil with a thickness of 0.03 mm was used as the heat transfer material. In addition, a Kanthal wire was installed in the fluid wrapping part (F) as a heating element, and heat was generated by approximately 50 W when energized. Heat exchange performance of 78, 69, 68% was obtained for v = l, 2, 3 LZs.

(Example 4)

FIG. 8 shows a reactor according to the fourth embodiment of the present invention. In this reactor, heating in the reactor described in FIG. 7 is performed by catalytic reaction of reaction components contained in the fluid. This reactor is a self-heat exchanger with the structure shown in Fig. 5. The catalyst (Η) is supported on the entire surface of the heat transfer body (BF) or the surface close to the end surface where the fluid circulates. It is an integrated catalytic reactor. In this reactor, the self-heat exchange structure with a bellows type heat transfer surface with a high heat exchange rate and the monolithic catalyst support structure are integrated, and the temperature of the reaction fluid is obtained as in the case of Fig. 7. Enough temperature for catalytic reaction inside the reactor (for example!), And the temperatures at F, D, 20 ° C :, 300 ° C, 50 ° C;), respectively, A highly efficient and energy-saving reaction can be realized.

Performance verification experiment of the fourth embodiment:

In order to actually verify the performance of the self-heat exchange type catalytic reactor of the fourth example, a stainless steel foil having a thickness of 0.03 mm, a width of 200 mm, and a length of 2720 mm is perpendicular to the longitudinal direction as a heat transfer body. In addition, it was folded into a total of 68 planes at intervals of 40 mm, and a rectangular bellows-shaped heat transfer body with a total shape of about 40 X 40 X 200 mm as shown in Fig. 5 was produced. At this time, the distance between adjacent surfaces of the folded heat transfer body was about 0.59 mm. Furthermore, after coating the alumina-supported platinum catalyst in a range of about 40 mm in width from the end surface of the heat transfer body where the fluid circulates in the direction of the fluid inlet / outlet, a rectangular parallelepiped container made of stainless steel with a thickness of 0.6 mm In. This container has access corresponding to D and D 'in Fig. 5. A vent was provided to circulate air containing low concentrations of volatile organic components (VOC). Table 3 shows the VOC removal performance and heat exchange performance results for this prototype # 2. At room temperature, these VOCs with a concentration of 0.3% or less can be converted into self-oxidation, that is, only by the heat generated by their own oxidation without any external auxiliary heat except during ignition. It was possible to continue to decompose more than 90%. With respect to toluene, flow rate 1. lL / s (SV = 1240 Oh) at a relatively high space velocity that completely C_〇 ₂ and H ₂ 0 concentration of about 0.1% of the toluene removal rate of about 94% Disassembled.

(Table 3)

Catalytic combustion of low-concentration combustible gas in a self-heat exchange type catalytic reactor (prototype No. 2)

In paint factories and the like, air pollution due to volatile organic components such as toluene and xylene (so-called VO C, vol at i le organic cco mpounds; has become a problem. However, if this reactor is used, for example, toluene The reaction temperature is maintained by using only the heat generated by the catalytic combustion of toluene by using an oxidation catalyst such as platinum catalyst without requiring additional heating energy for 0.1% air. In other words, this reactor can be expected to be applied to devices that treat low-concentration volatile organic pollutants in the air.

(Fifth embodiment)

FIG. 9 shows a reactor according to the fifth embodiment of the present invention. This reactor is a self-heat exchanger with the structure shown in Fig. 5. The catalyst (H) for reacting the reaction components contained in the fluid is supported on the entire surface of the body (BF) or the surface of the region near the fluid inlet / outlet, and the entire surface of the heat transfer body (BF) or It has a structure in which an adsorbent (I) that adsorbs reaction components at a low temperature and desorbs at a high temperature is supported on the surface of the region close to the end face of the heat transfer body (BF) through which the fluid flows.

According to this reactor, under transient reaction conditions in which the fluid temperature gradually rises, while the temperature is low, the adsorbent (I) is used to trap the reaction components. As the fluid temperature rises, it is heated from the part close to the inlet / outlet of the heat transfer body (B F), but the heating of the part where the fluid wraps around is considerably delayed due to the heat storage property of the heat transfer body (B F). For this reason, when the heat spreads over the entire heat transfer body (BF) and the adsorbed reaction components are desorbed, the temperature near the fluid outlet becomes higher and the conditions for the catalyst reaction to occur are achieved. Therefore, the reaction components are decomposed with high efficiency and do not come out to the discharge side. The reactor with such a structure is easy to get out at the start of the engine, and the exhaust gas temperature is low, which makes it difficult to treat with conventional catalyst components overnight. It is suitable as a companion overnight.

(Sixth embodiment)

FIG. 10 shows a reactor according to the sixth embodiment of the present invention. This reactor is a reactor integrated with a self-heat exchanger equipped with a heating element (G) with the structure shown in Fig. 7. A filter (J) that can trap fine particles is used as a heat transfer element (J The structure is in close contact with the end face of BF).

According to this reactor, by placing a filter (J) in the space (F) where the temperature is highest, carbon or high-boiling organic components that can be decomposed at high temperatures are removed from the fluid. This is a self-regenerating filter trap that can be processed without increasing the temperature of the inlet / outlet without applying much heat energy. Diesel engine Particulate matter (PM) in exhaust gas, especially solid carbon (soot) in it, can not be oxidized and removed promptly unless it exceeds 60 ° C. Conventionally, the exhaust gas temperature is intermittent However, there is a technology that oxidizes (PM) trapped in Phil and captured in the evening and regenerates the filter, but the energy (fuel) required for this has become considerable. However, this reactor has the advantage that the temperature at which PM oxidation occurs quickly can be obtained without applying much energy. In this reactor, if a PM oxidation catalyst containing Mo, V, etc. is supported on Phil Yuichi (J), the temperature to be reached can be reduced to 500 ° C, 400 ° C, etc. It is also possible to lower the energy loss. This reactor can be applied as a self-regenerating diesel particulate filter.

(Seventh embodiment)

FIG. 11 shows a reactor according to a seventh embodiment of the present invention. This reactor has a structure in which heating is carried out by catalytic reaction instead of providing the heating element (G) in the self-regenerative type filter trap described in Fig. 1 (b). In other words, this reactor is provided with a filter (J) for capturing and removing fine particles on the end face of the heat transfer body (B F) on the side where the fluid flows.

According to this reactor, the temperature in the filter (J) can be increased to a necessary level by adding as much catalytic reaction components as necessary to the fluid. As in Fig. 10, this reactor can be used as a self-regenerating fill trap that treats PM in diesel engine exhaust gas. Since the heating is performed by catalytic oxidation of the fuel, the heat energy utilization efficiency is higher than that through the heating element, so that it is more practical. This reactor can also be used as a self-regenerating diesel particulate filter.

(Eighth embodiment)

FIG. 12 shows a reactor according to the eighth embodiment of the present invention. This reactor uses a porous material (K) having a filter function as the heat transfer body (BF) in the self-heat exchanger having the structure shown in Fig. 5, and the fluid of the heat transfer body (BF) flows around. The space (F) at the end is eliminated and the space between the heat transfer body (BF) and the face (A,) is sealed. 02

18

In the reactor having this structure, the fluid entering from the inlet (D) passes through the heat transfer body wall, exits to the opposite surface, and is discharged from the outlet (D ⁵ ). Meanwhile, fine particles floating in the fluid are trapped on the surface of the heat transfer body. In this reactor, a catalyst that promotes the catalytic oxidation reaction is supported on the heat transfer body (BF), and the reaction components are added to the fluid just before entering the reactor. As in the case of, the heat transfer body / filter 1 itself is heated by the heat generated by the catalytic reaction. Furthermore, the self-heat exchange channel structure similar to that in Fig. 5 raises the temperature at the lower part of the heat transfer body, which is realized in the lower part of the region where fine particles are decomposed and removed. The degree of regeneration of the filter (shaking of fluid permeation) can be ascertained by means such as measuring the differential pressure across the reactor, and the heating degree of the reactor can be adjusted until it reaches the required level.

In addition, according to the present reactor, an alternating-sealed fine particle filter (Fig. 13; L is a porous wall having a filter function; M is a honeycomb-structured channel inlet / outlet). It is possible to obtain a fill area density similar to that of the alternately plugged sealant, and it is possible to regenerate the fill with less heat energy because of its self-heat exchange capability. This reactor can also be used as a self-regenerative diesel particulate fill.

(Ninth example)

Next, we will explain the radiation effect based on the self-heat exchanger with the structure shown in Fig. 5. FIG. 14 shows the radiation heat according to the ninth embodiment of the present invention. In the self-heat exchanger shown in Fig. 5, this radiant heat is applied to the combustion burner (N) in the space (F) where the fluid circulates and to the part of the wall that partitions the space (F) and the outside. It has a structure with a heat radiation plate (P) with a high heat radiation rate. In this radiant heat, a gas containing a combustion oxidant such as air that reacts with fuel (0) is used as the fluid. According to such a structure, by transferring the heat of the combustion exhaust gas to the inflowing gas having a low temperature, it is possible to obtain a high-efficiency radiant heat with less heat energy discarded to the combustion exhaust gas. This radiant heat can be applied as an energy-saving gas-fired heater with little loss of thermal energy to the flue gas. (Example 10)

FIG. 15 shows the radiation effect according to the 10th embodiment of the present invention. This radiant beam is a radiant beam that uses a catalytic reactor integrated with the self-heat exchanger in Fig. 8, and is part of the wall that separates the space (F) where the fluid circulates from the outside. It has a structure with a heat radiating plate (p) with high thermal conductivity and high heat emissivity. In this radiation heater, a fluid containing a reaction component that reacts exothermically by the action of the catalyst is used. Usually, an oxidation catalyst such as platinum is used as the catalyst, and a mixture of hydrocarbon and air is used as the fluid. It only has to be.

According to such a structure, most of the exhaust heat carried by the fluid generated by the catalytic reaction is transferred to the inflowing fluid at a low temperature, so that the highly efficient radiation heat with less exhaust heat energy discarded to the fluid is obtained. It can be evening. This radiant heat can also be applied as an energy-saving gas combustion heater with little loss of thermal energy to the combustion exhaust gas.

The embodiments of the present invention have been described above. Next, some typical modifications of the embodiments of the present invention will be described.

(Modification 1)

In Modification 1, in the second embodiment, at least one type of structure having air permeability different from that of the heat transfer body (BF)-is provided in the gap portion of the bellows portion of the heat transfer body (BF). It is sandwiched between the top. This structure is made to play the role of a spacer.

Fig. 16 shows a structure in which a stainless steel mesh piece (m, m ⁵ ) that has almost the same shape as one bent surface of a bellows-type heat transfer body (BF) is used. BF) is sandwiched between all the voids. By sandwiching such a structure, the heat transfer surface spacing becomes uniform, the heat radiation in the gap of the bellows type heat transfer body (BF) is blocked, and the heat insulation in the flow path direction is increased. The heat transfer through the structure increases between adjacent heat transfer surfaces, the temperature in the direction perpendicular to the flow path becomes uniform, and the mechanical strength of the structure of the bellows heat transfer body (BF) increases. Effective, improving heat exchange performance and durability Can be raised. In order to improve the air permeability and reduce the pressure loss in the heat exchanger, use the one with as large an opening ratio as possible, that is, one with a large mesh interval (opening ratio) relative to the diameter of the wire wire used for the net. Is desirable. The mesh direction is either square with respect to the ridge line (or valley line) of the heat transfer element (BF) as shown in Fig. 16, or diagonally as shown in Fig. 17 (a). Also good. In addition, instead of a wire mesh piece with a cut surface of the wire at the end, as shown in Fig. 17 (b), a wire-wire bent into a loop shape and processed into a wire mesh shape can be used. It is possible to prevent damage to the heat transfer body (BF) and the below-mentioned filler material at one end of the wire.

Next, an example of the verification result of Modification 1 is shown. Table 4 shows a bellows-shaped transmission in which stainless steel foil with the same dimensions as the prototype No. 1 unit, ie, a thickness of 0.03 mm, a length of 1600 mm, and a width of 200 mm, is bent into 40 planes every 40 mm perpendicular to the length direction. As for the thermal element (BF), an alumina-supported white metal catalyst is supported on both surfaces with a width of about 100 mm in the vicinity of the fluid wrapping side, and a plain weave stainless steel wire mesh with a 0.44 mm wire diameter

Self-heat exchange type catalytic reactor (prototype No. 3) with 39 structures with an open area of 73.9% squared in a 40 x 175 mm rectangle and a bellows-shaped gap. This shows the performance. In this case, the gap interval was about 1 mm. Regardless of VO (, the reaction continued in an auto-oxidative manner under the reaction conditions shown in Table 4. As is clear from the results in Table 3, the heat transfer area is about 2/3. Nevertheless, the heat exchange rate improved by more than 10% under the same flow rate condition, and in the case of toluene, the heat exchange rate reached 92% under the flow rate condition of 0.64 L / s. The V 0 C concentration, which can continue catalytic combustion in an auto-oxidative manner, has become extremely small, and with toluene at the same flow rate, the reaction proceeds even at a low concentration of 0.023%. For example, even at a high space velocity of 2.92 LZs (= 32800 h, 0.06% of trout is autooxidatively with 99% removal rate. Completely decomposed into 0 ₂ and H ₂ 0.

(Table 4) Catalytic combustion of low-concentration combustible gas in a self-heat exchange type catalytic reactor (prototype No. 3)

(Modification 2)

In the second modification, a material having a filter function is formed into a bellows type heat transfer body (BF) using a spacer structure in the eighth embodiment.

According to the modified example in which the structure as a spacer is sandwiched in the gap of the heat transfer body ', a material with low structural strength, which has been thought to be difficult to use as a heat transfer body until now, is also a bellows type heat transfer body ( BF) can be used. Fig. 18 shows a bellows shape by combining a heat-resistant film Yuichi Cross (FC) with the structure (m, m ⁵ ), which has the function of capturing combustible fine particles such as particulate matter discharged from a diesel engine. It was used as a heat transfer body (BF) (self-heat exchanger-type Phil Yuichi trap). Folding one end of the filter cloth (FC) to increase the thickness (R in Fig. 18 (a)), folding it further into a bellows shape, and then compressing the filter cloth (FC) from the horizontal direction, The gap on one side is closed by the filter cross (FC) itself at one end in the longitudinal direction of the bellows. Place this in a rectangular parallelepiped container with a channel inlet and outlet, and seal the end face that does not fold back the film with an appropriate sealing material (Fig. 18 (b) s). At the same time, close the area where the folded part (R) of the Phil Yuichi Cross (FC) is folded back and the heat exchanger container with close contact or a suitable sealing material (not shown). As a result, it becomes a self-heat exchange type Phil evening trap. In other words, Fig. 18 (b) is a front perspective view of this structure.

The fluid (typically combustion exhaust gas) containing combustible particulates entering from (D) moves down the front gap where the spacer (m) is located and traps too much particulates. It passes through the filter cloth (FC) at the part with high air permeability that is not installed, flows upward through the gap on the back side where the spacer (m ') is located, and from the back side outlet (D') Discharged. During this time, self-heat exchange is performed between the forward side and the return side. In addition, Fig. 19 (a) shows that not only is the thickness of the fill evening cross (FC) similar to that of Fig. 18 (a) folded to increase the thickness, but the other end is also folded to the opposite side to increase the thickness. After holding, it is a front perspective view of a self-heat exchanger type filter evening trap that has a bellows shape using a spacer (m: arranged on the front side, m ,: arranged on the back side). In this way, both ends of the bellows-shaped gap are alternately plugged. As a result, the seal material (s) shown in FIG. 18 (b) is unnecessary, and the structure as a self-heat exchange type filter trap can be simplified. Also, in this alternately sealed bellows-shaped heat transfer body (BF), as shown in Fig. 19 (b), the fluid inlet (D) should be brought upward rather than the front side as before. Is also possible. The outlet (D ') is on the back side as in Fig. 19 (a). By setting the entrance at this position, the fluid easily flows evenly into the plurality of outward gaps of the bellows type heat transfer body (BF), so that the heat exchange performance and the particulate capturing function are improved. Of course, in this case, it is also possible to set the flow direction to the opposite direction.

(Modification 3)

This modified example 3 is the one in which a functional material such as a catalyst, an adsorbent, a heat storage material, a fill material, etc. is sandwiched in the gap portion of the bellows portion of the heat transfer body (BF) in the second embodiment. Well.

In Examples 4, 5, and 8, the catalyst, the adsorbent, and the heat storage material are all heat transfer bodies (BF). In this modified example 3, these functional materials are sandwiched between the heat transfer body gaps separately from the heat transfer body (BF). It is.

The first of the third modification is a structure in which the spacer structure used in the first modification carries functional materials such as a catalyst, an adsorbing material, and a heat storage material.

The second modification 3 uses a structure that combines a role as a spacer and a functional material. For example, it is possible to use a technique in which a pellet type catalyst having a substantially uniform particle size and appropriate mechanical strength is further packed in the gap.

In addition, the third modification 3 has a structure in which a functional material is sandwiched in addition to the spacer structure.

Here, FIG. 20 shows a third example of the third modification. In this example, the end where the fluid wraps around the bellows type heat transfer body (BF) with the same spacers as shown in Fig. 16 (m: forward path side and m ': return path side). The neighborhood is shown. In this vicinity, a belt-shaped heat-resistant cloth (CL) carrying a functional material such as a catalyst is further sandwiched between the heat transfer body (BF) and the spacer (m '). By sandwiching a functional material separate from the heat transfer body (BF) in this way, it becomes possible to place the functional material only on the forward or return path side as a self-heat exchanger. Improvements can be made.

In addition, a demonstration example of the third example (Fig. 20) of Modification 3 is shown. Table 5 shows the self-heat exchanger with the same size and the same mesh structure (m, m ') as the prototype No. 3, except that the catalyst was not supported on the heat transfer body (BF). Self-heat exchange type catalytic reactor (prototype No. 4) with a heat-resistant cloth (CL) carrying a platinum catalyst that is 1600 mm long and 40 mm wide and sandwiched only on the return path near the end of the fluid wrap. The performance is shown. Compared to the results in Table 4, the heat exchange rate under the same conditions is improved by about 2%. As for ethylene, a high heat exchange rate almost equal to the theoretical value shown in Table 1 was obtained even at a high space velocity of 1.98 L / s (22 300 h " ¹ ). The In addition to the effect of the spacer structure (m, m ⁵ ) described above, the catalyst reaction occurs only on the return path side, so that the heat exchange to the upstream side (outward path side) is easy. This is probably because of this.

The fluid used here is room temperature air with a force of 0.1 to 1 mg / "L suspended in a bomb, and simulates diesel exhaust. To increase the reaction temperature, H ₂ The flow rate of this mixed gas was 0.33 LZs, and as a result, the reaction heat and the self-exchange function when H ₂ was oxidized on the platinum catalyst turned the reactor back. The average temperature T _r in the zone rises to 567 ° C and is generated by the oxidation of force-bon black that is 0.109 g (2 W _c ) The amount of incinerated carbon calculated from C0 ₂ and CO is 0.175 g (2 W _COx ).

(Modification 4)

This modified example 4 is a self-heat exchange type heat exchanger having the same function as that of the second embodiment, wherein a part of the heat transfer body surface is opened, and this is used as a fluid wraparound part. 2 The fluid wraparound part (F) of the self-heat exchange type heat exchanger described in the example uses the end face formed by bending the heat transfer body (BF) in the shape of a bellows. A first modification of the fourth modification is that a part of the thermal body edge is cut to arbitrarily form the boundary around which the fluid flows and the shape of the space. Figure 21 shows a specific example.

Shown in (a). In this case, a part of the heat transfer body (BF) is cut into a trapezoidal shape on one bent surface of the bellows type heat transfer body (BF) to form a fluid wrap-around part (Q). Other faces may be cut together, or the location may be shifted, or the cut shape may be changed to a triangle, rectangle, or other shape. In this way, the fluid wrap-around space can be formed without providing a gap between the heat transfer body (BF) and the sealing material (s ⁵ ).

The second of the fourth modification is that, in the second embodiment, an opening having a closed periphery is provided on each bent surface of the heat transfer body (BF), and this is used as a fluid wraparound. An example is shown in Fig. 21 (b). This is a circular opening (S) provided at a location away from the fluid inlet / outlet of each folded surface of the bellows type heat transfer body (BF). At this time, the fundamental difference from Fig. 21 (a) is that the opening does not overlap the end of the heat transfer element (BF) and occupies a closed planar area. As shown in the figure, there may be a plurality of openings (S) or a single opening (S). By providing such an opening (S), it is possible to form a flow path for self-heat exchange without providing a space for fluid wraparound on the end face of the heat transfer body.

(Modification 5)

Modification 5 is a combination of a non-breathable heat transfer body (BF), a spacer structure, and a fill evening cross. That is, in Modification 1 in which a heat transfer body (BF) and a spacer structure (m, m, for example, a wire mesh) are combined, The structure is further extended from the end face of the fluid wrapping part of the heat transfer body (BF), and a Phil evening cross (FC) is formed in the shape of a bellows around it.

FIG. 22 shows an example of the fifth modification. As shown in Fig. 22 (a), a rectangular spacer (m ') is sandwiched on the return path side of the non-breathable heat transfer body (BF). At that time, place the end of the _spacer ( _Π1 ') so that it protrudes from the end face of the heat transfer body (BF). Next, fill the evening cross, which is formed in a bellows shape and folded at the end so as to cover a part of the heat transfer body (BF) and the protruding part of the spacer (m '). Cover with (FC). In addition, the spacer (m) is sandwiched between the forward air gap so that it does not overlap the R part and spans both the fill-cross (FC) and the heat transfer body (BF).

FIG. 22 (b) is a cross-sectional view showing the positional relationship of these components more clearly, taken from a plane perpendicular to the heat transfer surface. Since the Phil Yuichi Cross (FC) extends from the end face of the heat transfer body (BF) and the tip is sealed with the folded part, the fluid passes through the Phil Yuichi Cross (FC) and the spacer ( It has a structure that flows to the return side with m ') in between, and as a result, it functions as a self-heat exchanger with a fill evening trap. Alternatively, the end of the return-side gap may be sealed by reversing the direction of the Phil Yuichi Cross (FC) (right of Fig. 22 (b)).

(Modification 6)

This modified example 6 is a self-heat exchange type filter that combines a heat transfer body (BF) having the shape of modified example 4, a spacer structure (m, m ⁵ ), and a filter cloth. It is. FIG. 23 shows two examples of Modification 6.

In Fig. 23 (a), instead of projecting the spacer from the end of the heat transfer body, a notch as shown in Fig. 2 (a) is made at the end of the heat transfer body, and the filter cloth (FC ) And the spacer structure (m, m ⁵ ), the ventilation part (Q) has the function of filling even if the outward spacer (m) does not protrude from the end of the heat transfer body. ) Is formed. In this way, the heat transfer body (BF) and the spacer (m) The end faces can be aligned, making it easy to assemble as a Phil evening trap. Also, using a heat transfer body (BF) with an opening that does not overlap with the end of the heat transfer body as shown in Fig. 21 (b), and the A spacer structure (m, m ⁵ ) may be arranged. In this way, the end faces of the heat transfer body (BF), Phil Yuichi Cross (FC), and spacer 1 (m ⁵ ) overlap (the end face of spacer 1 (m) is R by this amount. It is easier to assemble as a filter trap. Industrial applicability

As described above, the heat exchanger according to the present invention, the reactor using the heat exchanger, and the radiation heater have a large heat exchange surface within a limited capacity and are relatively easy to manufacture. Since the exchange efficiency is dramatically improved, this heat exchanger is a self-heat exchange type, and a self-heat exchange reactor that combines a self-heat exchanger with a catalytic reaction or combustion burner, and energy saving. It is suitable for use in the field of thermal engineering to save energy consumption and environmental technology for the purpose of purifying exhaust gas.
