Description

TECHNICAL FIELD

[0001] The utility model relates to the field of condenser, especially to a condenser and heat exchange system that avoid the falling of the anti-collision plate. BACKGROUND

[0002] In the heat exchange system of the evaporation and absorption process of soda production, the condenser is mainly involved in the heat and mass transfer process. When the gas enters the condenser, it exchanges heat with the cooling medium (mother liquor), and the heat in the gas is absorbed and carried away by the cooling medium, causing the gas temperature to decrease and gradually condense into liquid. This process is achieved through the tube plate, tube bundle, and tube row structures inside the condenser, which optimize the heat transfer path and efficiency. As an important equipment in the heat exchange system of the evaporation and absorption process, the performance and efficiency of the condenser directly affect the yield and quality of the product. Therefore, in the soda industry, high-efficiency and reliable condenser equipment is usually selected to ensure the stable operation and efficient production of the evaporation and absorption system.

[0003] The anti-collision plate is a part that protects the tube row and is arranged inside the condenser. Its plate surface is located between the tube row and the gas inlet to prevent the fluid from directly impacting the tube row inside the condenser.

[0004] Currently, the anti-collision plate inside the condenser is welded to the inner wall of the condenser. However, in the soda industry, due to the long single working time of the condenser in the evaporation and absorption heat exchange system, the fixed anti-collision plate may break at the fixed position with the inner wall of the condenser after being impacted by the gas for a long time, causing the anti-collision plate to fall off. The fallen anti-collision plate may hit the tube row, causing the tube row to break, and thus the condenser stops working, delaying equipment production. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0029] The specific implementation of the utility model is described in further detail below in combination with the drawings and embodiments. The following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model.

[0030] Embodiment one:

[0031] As Figures 1 to 4 shown, the utility model provides a kind of condenser to avoid anti-impact board 2 to fall off, the condenser includes: condenser main body 1, several anti-impact boards 2 and several fixed plates 4.

[0032] The condenser main body 1 is provided with cooling chamber 101, the cooling chamber 101 is the cavity inside the condenser main body 1, the cooling chamber 101 is opened with the air inlet that communicates with outside, the air inlet is communicated with air inlet pipeline, the air inlet pipeline continuously passes into gas into cooling chamber 101, cooling area 1011 is provided in the cooling chamber 101, several rows of pipes 3 are provided in the cooling area 1011, cooling medium is passed into several rows of pipes 3 to realize heat exchange with gas.

[0033] The two ends of the fixed plate 4 are fixed on the inner side wall of the cooling chamber 101 respectively, several fixed plates 4 are located between air inlet and cooling area 1011, several fixed plates 4 are sequentially arranged along the axial direction of the row of pipes 3, the side plate surface of the fixed plate 4 towards air inlet and the side plate surface towards cooling area 1011 are all parallel to the axis of the row of pipes 3; to avoid interfering with the flow direction of the air inlet entering gas, the thickness of the fixed plate 4 body is as thin as possible under the condition of guaranteeing the fixing effect, the width direction of the fixed plate 4 is parallel to the air inlet direction of the air inlet, the thickness direction of the fixed plate 4 is parallel to the axial direction of the row of pipes 3, and the plate body width of the fixed plate 4 is greater than the plate body thickness of the fixed plate 4.

[0034] Several anti-impact boards 2 are vertically arranged, and sequentially arranged from the direction of air inlet and cooling area 1011, and each anti-impact board 2 is fixed on several fixed plates 4; the anti-impact board 2 is provided with several pressure relief holes 203 penetrating the opposite two plate surfaces thereof, the axis of the pressure relief hole 203 is parallel to the flow direction of the air inlet gas, and the plate surface of the anti-impact board 2 faces the air inlet, the pressure relief hole 203 disperses the gas impact force received by the plate surface of the anti-impact board 2, prolongs the service life of the anti-impact board 2 from the perspective of pressure distribution.

[0035] Because in soda industry, the gas condensed by condenser is relatively complex and contains water vapor with high temperature, when using rubber material anti-impact board 2, the condensed water adhered to the anti-impact board 2 of this kind of material can corrode rubber and reduce the service life of the anti-impact board 2, when using plastic material anti-impact board 2, the anti-impact board 2 will not be corroded by gas, but the fixation of the plastic anti-impact board 2 in the condenser needs to rely on external structure, and the connection position is relatively weak due to the limitation of material, so it is more prone to breakage than the anti-impact board 2 of metal material when needing to use for a long time, therefore, the anti-impact board 2 of the present condenser uses metal material.

[0036] Based on this, when the condenser is working, the gas that needs to be cooled flows into the column tube 3 in the cooling area 1011, and the baffle 2 arranged between the gas inlet and the cooling area 1011 blocks the moving path of the gas by the baffle surface to avoid the direct impact of the gas on the column tube 3, which causes damage to the column tube 3. The fixed plate 4 provides a fixed position for the baffle 2, and the pressure relief hole 203 arranged through the baffle surface of the baffle 2 can allow a small amount of gas to flow in from the hole to disperse the pressure on the baffle surface of the baffle 2. The condenser increases the service life of the baffle 2 in the condenser from two aspects of reducing pressure and enhancing structural strength, and solves the problem that the baffle 2 in the existing condenser is easy to fall off under the continuous impact of the gas and damage the column tube 3.

[0037] Further, as shown in Figures 1 to 4 A part of the baffles 2 are fixedly arranged in the first vertical plane, and another part of the baffles 2 are fixedly arranged in the second vertical plane.

[0038] The end of the baffle 2 in the first vertical plane farthest from the cooling area 1011 is fixedly connected with the side wall of the fixed plate 4 in the first vertical plane, and the baffle 2 in the first vertical plane blocks the gas flowing to the baffle surface and makes it flow to the two side walls adjacent to the baffle surface, respectively. The end of the baffle 2 in the second vertical plane farthest from the gas inlet is fixedly connected with the side wall of the fixed plate 4 in the second vertical plane, and the baffle 2 in the second vertical plane blocks the gas flowing to the baffle surface and makes it flow to the two side walls adjacent to the baffle surface, respectively.

[0039] At this time, the baffle 2 in the first vertical plane and the baffle 2 in the second vertical plane will transmit the force to the fixed plate 4 after being impacted by the gas. The connection position of the fixed plate 4 is on the side wall of the cooling chamber 101, and the position with the slowest gas flow rate in the cooling chamber 101 is the position. Therefore, from a macro perspective, the fixed plate 4 at the connection position will only be affected by the gas impact force transmitted by the baffle 2. However, since the plate body of the fixed plate 4 has a certain length, the force will be partially offset by the internal force of the plate structure during transmission. Therefore, compared with the existing condenser in which the baffle 2 is directly fixed in the cooling chamber 101, the fixed plate 4 has better fixing effect.

[0040] Further, as shown in Figures 1 to 3 The baffle 2 in the first vertical plane is a first baffle 201, and the baffle 2 in the second vertical plane is a second baffle 202.

[0041] The first baffle plate 201 and the second baffle plate 202 are staggered, and the second baffle plate 202 and the first baffle plate 201 adjacent to the second baffle plate 202 have an airflow passage 8 in the direction from the air inlet to the cooling area 1011. The width of the projection of the airflow passage 8 in the axial direction of the tube 3 is the width of the fixed plate 4. The airflow passage 8 communicates the air inlet and the cooling area 1011 to ensure the flow rate of the gas after being decelerated by the first baffle plate 201 and the second baffle plate 202. The working efficiency of the condenser is increased by guiding the gas flow path.

[0042] Further, as shown in Figures 1 to 3 , the first baffle plate 201 is provided with two first baffle plates 201, and a gap is left between the two first baffle plates 201. The second baffle plate 202 is provided with one. In the direction from the air inlet to the cooling area 1011, the width of the second baffle plate 202 covers the gap. Compared with the whole baffle plate 2 of the prior art condenser, the first baffle plate 201 and the second baffle plate 202 reduce the area of the baffle plate 2 subjected to the impact of the gas, and reduce the risk of the baffle plate 2 being broken by the impact of the gas.

[0043] In the direction from the air inlet to the cooling area 1011, the projections of the two first baffle plates 201 and the second baffle plate 202 completely cover the flow path of the gas. Therefore, the two first baffle plates 201 and the second baffle plate 202 completely block and decelerate the gas entering from the air inlet, so as to avoid the direct impact of the gas on the tube 3, which causes the tube 3 to not work normally.

[0044] Further, as shown in Figures 1 to 3 , the top wall of the baffle plate 2 and the top wall of the cooling chamber 101 leave a gap, and a part of the gas entering from the air inlet flows through the gap, thereby increasing the flow rate of the gas after being blocked by the baffle plate 2.

[0045] The bottom wall of the baffle plate 2 is fixedly connected with the bottom wall of the cooling chamber 101. The baffle plate 2 is fixedly connected with the bottom wall of the cooling chamber 101 by plug-in connection or welding. The baffle plate 2 increases the fixed fulcrum with the cooling chamber 101 to further prolong the service life.

[0046] Further, as shown in Figures 1 to 3 , a first reinforcing plate 6 is further arranged between two adjacent fixed plates 4. The top surface and the bottom surface of the first reinforcing plate 6 are fixedly connected with the two adjacent fixed plates 4, respectively.

[0047] The number of the first reinforcing plate 6 is not limited here. The first reinforcing plate 6 only needs to satisfy the fixation of the two adjacent fixed plates 4. The first reinforcing plate 6 does not close the space between the two adjacent fixed plates 4. The first reinforcing plate 6 fixedly connects the two adjacent fixed plates 4 to further reinforce.

[0048] Further, as shown in Figures 1 to 3 The second anti-collision plate 202 is located in the third plane, and the auxiliary fixing plate 5 is fixedly connected to the side end surface of the second anti-collision plate 202 closest to the air inlet in the third plane. The two ends of the auxiliary fixing plate 5 are fixed on the side wall of the cooling chamber 101. The auxiliary fixing plate 5 reinforces the second anti-collision plate 202.

[0049] Further, as shown in Figures 1 to 3 The first reinforcing plate 6 is arranged between two adjacent fixing plates 4. The top surface and the bottom surface of the first reinforcing plate 6 are fixedly connected to the two adjacent fixing plates 4, respectively.

[0050] The number of the first reinforcing plate 6 is not limited here. The first reinforcing plate 6 only needs to satisfy the fixing of the two adjacent fixing plates 4. The first reinforcing plate 6 does not close the airflow channel 8, and the first reinforcing plate 6 is fixedly connected to the two adjacent fixing plates 4 to further reinforce.

[0051] Further, as shown in Figures 1 to 3 The second reinforcing plate 7 is arranged between two adjacent fixing plates 4. The top surface or the bottom surface of the second reinforcing plate 7 is fixedly connected to one of the two adjacent fixing plates 4, and one side surface of the second reinforcing plate 7 is fixedly connected to the adjacent anti-collision plate 2.

[0052] The number of the second reinforcing plate 7 is not limited here. The second reinforcing plate 7 only needs to satisfy the fixing of the adjacent anti-collision plate 2. The second reinforcing plate 7 does not close the airflow channel 8, and the second reinforcing plate 7 is fixedly connected to the adjacent anti-collision plate 2 to further reinforce.

[0053] It should be noted that the more the number of the first reinforcing plate 6, the second reinforcing plate 7, and the fixing plate 4, the more complex the channel structure of the airflow channel 8, and the slower the flow speed of the airflow. Therefore, when setting, the flow speed of the airflow in the condenser also needs to be considered, and the number of the corresponding plate should not be excessively increased.

[0054] Further, the anti-collision plate 2 and the fixing plate 4 are fixed by argon arc welding.

[0055] Example two:

[0056] As shown in Figures 4-7As shown, the condenser of the embodiment is different from that of the first embodiment in that a plurality of auxiliary fixing plates 5 are further arranged in the condenser, the two ends of the plurality of auxiliary fixing plates 5 are fixed on the inner side walls of the cooling chamber 101, the plurality of auxiliary fixing plates 5 are arranged in sequence along the axial direction of the tube bank 3, one side of the auxiliary fixing plate 5 is fixedly connected with the plate surface of the second anti-collision plate 202 facing the air inlet, and the other side of the auxiliary fixing plate 5 extends to the direction of the air inlet; at least one second reinforcing plate 7 is arranged between two adjacent auxiliary fixing plates 5, at this time, the top surface or the bottom surface of the second reinforcing plate 7 between the auxiliary fixing plates 5 is fixedly connected with one of the auxiliary fixing plates 5, and one side of the second reinforcing plate 7 is fixedly connected with the second anti-collision plate 202 adjacent thereto.

[0059] The working process of the utility model is as follows: after the gas inlet connected with the outside world is input with the gas needing to be cooled, the first anti-collision plate 201 and the second anti-collision plate 202 are installed on the plurality of fixing plates 4 between the cooling area 1011 provided with the tube bank 3 and the air inlet, the first anti-collision plate 201 is fixedly connected with the plurality of fixing plates 4 in the first plane, and the second anti-collision plate 202 is fixedly connected with the plurality of fixing plates 4 in the second plane; after the gas with initial velocity impacts the second anti-collision plate 202, part of it flows out from the pressure relief hole 203, and part of it flows to the side wall of the second anti-collision plate 202; since the gas loses energy in the process, the second anti-collision plate 202 makes the gas decelerate for the first time; the gas after the first deceleration passes through the airflow passage 8 between the second anti-collision plate 202 and the first anti-collision plate 201, part of the gas directly passes through the second anti-collision plate 202 and enters the cooling area 1011, and the other part of the gas impacts the first anti-collision plate 201 in the moving process; the first anti-collision plate 201 makes the gas decelerate for the second time after being impacted, so as to avoid the damage of the tube bank 3 caused by the direct impact of the gas on the tube bank 3.

[0061] The above merely describes the preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, some improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
