Description

A kind of pipe heat exchanger with alignment pin
Technical field
The utility model relates to a kind of pipe heat exchanger, especially relates to a kind of pipe heat exchanger with alignment pin.
Background technology
Heat exchanger is simple in structure, lightweight now, and cost is lower, in identical shell situation, can arrange some heat transfer pipes compared with the tubular heat exchanger of other patterns more.But the temperature difference of the fluid between housing and pipe layer can not be too large, because the temperature difference is when too large, can produce larger thermal stress, make tube-to-tube sheet connection junction get loose and produce leakage.In addition this class heat exchanger is fixed because of tube sheet, so in maintenance, when retubing or cleaning shell, all more difficult.It is less scaling that this heat exchanger is applicable to shell side medium, or have fouling but can carry out the occasion of Chemical cleaning; Shell wall and tube wall because of the difference of the swell increment that temperature difference causes little, though or the large not high situation of shell side pressure of differential expansion.
Application number is that 201110050362.8 Chinese patent discloses a kind of detachable tube type heat exchanger, comprise that shell, upper perforated plate, lower perforated plate, heat exchanger tube, upper lower perforated plate are arranged on respectively the upper and lower side of shell, only by a groove, and a sealing ring is set in groove connects, although said structure is for convenience detach, sealing effectiveness is bad.
Close in utility model
The purpose of this utility model is exactly to provide a kind of good effect of heat exchange, the pipe heat exchanger with alignment pin for convenience detach in order to overcome the defect of above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
With a pipe heat exchanger for alignment pin, some tubulations that be arranged in parallel in the housing of heat exchanger, the two ends of tubulation are fixedly connected with the end socket of heat exchanger,
Horizontal hydraulic barrier is set in described housing,
In described tubulation, longitudinal baffle is set,
On described end socket, offer groove and the fixing alignment pin of tubulation and longitudinal baffle, in described groove, be provided for sealing the sealing ring of tubulation.
The horizontal hydraulic barrier being arranged in housing is separated into heat exchanger channels by tubulation.
In heat exchanger channels, fin can also be set, these fin both sides seal through strip of paper used for sealing.
Described fin is plain fin, perforated fin, saw tooth fin and corrugated fin.
Described groove offers twice, parallel being opened on end socket.
Described sealing ring is the sealing ring of quality of rubber materials.
Described alignment pin is arranged on the side of end socket.
In pipe heat exchanger, carry out two kinds of fluids of heat exchange, a kind of mobile in tubulation, its stroke is called tube side; A kind of mobile outward at tubulation, its stroke is called shell side.The wall of tubulation is heat-transfer area.For improving extratubal fluid heat transfer coefficient, the horizontal baffle plate of some is installed in housing conventionally.Baffle plate not only can prevent fluid short circuit, increases fluid velocity, also force fluid in accordance with regulations path repeatedly cross-flow by tube bank, less turbulence is greatly increased.Fluid is often once called a tube side by tube bank in pipe, often by housing, is once called a shell side.For improving the speed of tube fluid, suitable dividing plate can be set in the end socket of two ends, whole pipe average marks are divided into some groups.Like this, fluid can only come and go tube bank repeatedly by part pipe at every turn, is called multitube distance.For improving the outer flow velocity of pipe, longitudinal plate washer can be installed in housing and make fluid Multiple through then out shell space, claim muitishell.In pipe heat exchanger, because the inside and outside fluid temperature (F.T.) of pipe is different, the temperature of housing and tube bank is also different.
Compared with prior art, the utlity model has following advantage:
1, usefulness is high: because of the disturbance of fin convection cell, the boundary layer that forms thermal resistance is constantly updated, heat transfer coefficient is generally 3 times of shell-and-tube heat exchanger; And under the little temperature difference (1.5~2 ℃), heat (cold) amount recovering effect is good.During for the heat exchange of gas-gas, effect is best.
2, compactness: because most of heat is to transmit by flat board through fin, the heat transfer area of FU volume can reach 1500 meters/meter.
3, lightweight: when heat transfer area is identical, weight is bordering on 1/5 of shell-and-tube heat exchanger.
4, firm: because plate Shu Weiyi single piece and fin play supporting role between two flat boards, therefore can bear higher operating pressure.In addition, also can in same equipment, realize multiple fluid heat exchange simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation at the utility model end socket place.
In figure, 1 is that end socket, 2 is that groove, 3 is that sealing ring, 4 is alignment pin.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
A kind of pipe heat exchanger with alignment pin, some tubulations be arranged in parallel in the housing of heat exchanger, the two ends of tubulation are fixedly connected with the end socket of heat exchanger, horizontal hydraulic barrier is set in housing, longitudinal baffle is set in tubulation, and the structure of end socket 1 as shown in Figure 1, offers groove 2 and the fixing alignment pin 4 of tubulation and longitudinal baffle on end socket 1, groove 2 offers twice and is set in parallel, and is provided for sealing the sealing ring 3 of the quality of rubber materials of tubulation in groove 2.Alignment pin 4 is arranged on the side of end socket 1.The horizontal hydraulic barrier arranging in housing is separated into heat exchanger channels by tubulation.In addition, in heat exchanger channels, fin can also be set, these fin both sides seal through strip of paper used for sealing.The fin that can adopt has plain fin, perforated fin, saw tooth fin and corrugated fin.
Described, parallel being opened on end socket.
The sealing ring that described sealing ring is.
In pipe heat exchanger, carry out two kinds of fluids of heat exchange, a kind of mobile in tubulation, its stroke is called tube side; A kind of mobile outward at tubulation, its stroke is called shell side.The wall of tubulation is heat-transfer area.For improving extratubal fluid heat transfer coefficient, the horizontal baffle plate of some is installed in housing conventionally.Baffle plate not only can prevent fluid short circuit, increases fluid velocity, also force fluid in accordance with regulations path repeatedly cross-flow by tube bank, less turbulence is greatly increased.Fluid is often once called a tube side by tube bank in pipe, often by housing, is once called a shell side.For improving the speed of tube fluid, suitable dividing plate can be set in the end socket of two ends, whole pipe average marks are divided into some groups.Like this, fluid can only come and go tube bank repeatedly by part pipe at every turn, is called multitube distance.For improving the outer flow velocity of pipe, longitudinal plate washer can be installed in housing and make fluid Multiple through then out shell space, claim muitishell.In pipe heat exchanger, because the inside and outside fluid temperature (F.T.) of pipe is different, the temperature of housing and tube bank is also different.
