Description

Technical Field

[0001] The utility model belongs to the technical field of deaerators, in particular to a gas-liquid separation structure for a rotary film deaerator. Background Art

[0002] The rotary film deaerator is mainly used to remove oxygen from water to prevent the gas in the water from oxidizing and corroding thermal equipment and its pipelines. It is widely used in boiler water treatment, heat exchanger systems, chemical and pharmaceutical industries. The rotary film deaerator needs to use a gas-liquid separation structure to separate the steam from the gas and liquid, so that the water remains inside the rotary film deaerator, and the gas is discharged from the rotary film deaerator to achieve the purpose of deoxygenation. There are usually three types of separation for gas-liquid separation: baffle type, steam cyclone type and adsorption type. Among them, the baffle type is to make the fluid change the flow direction many times. Since the suspended water droplets have a large mass and inertia, when the flow direction changes when encountering the baffle, the dry steam can bypass the baffle and continue to move forward, and the water droplets will accumulate on the baffle to form water droplets to complete the separation. However, when the prior art uses the baffle type for separation, the temperature of the baffle is close to the steam temperature, resulting in poor condensation effect of the steam. At the same time, the prior art mostly fixes the baffle by bolts or welding, which makes the baffle more troublesome to disassemble and assemble.

[0003] To this end, we provide a gas-liquid separation structure for a rotary film deaerator to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1, please refer to Figure 1-6 The utility model is a gas-liquid separation structure for a rotary film deaerator, comprising a box body 2, which is fixed at the steam outlet of the rotary film deaerator. A plurality of condensation boxes 1 are plugged into the front and rear sides of the box body 2 to realize the condensation of steam. The thickness of the inner end of the condensation box 1 is greater than the thickness of the left end, so that the condensed liquid can flow to the inner end of the lower wall of the condensation box 1, which plays a role in guiding the liquid. The adjacent condensation boxes 1 are partially overlapped in the upper and lower directions, so that the steam moves in a serpentine manner. The left and right side walls of the box body 2 are respectively fixed with a diverter box 201 and a collector box 202. The position of the condensation box 1 corresponds to The left delivery pipe 201a and the right delivery pipe 202a are fixed on the flow dividing box 201 and the flow collecting box 202 respectively. A delivery pump 3 is arranged on the right side of the box body 2. The liquid inlet and liquid outlet ends of the delivery pump 3 are fixed with connecting pipes 301. A heat dissipation box 4 is arranged on the right side of the delivery pump 3. A water inlet pipe 402 is fixed on the right wall of the heat dissipation box 4. When the water pump is working, the coolant flowing through the condensation box 1 can be transported to the heat dissipation box 4 through the right delivery pipe 202a and the flow collecting box 202 for heat dissipation. The coolant after heat dissipation passes through the flow dividing box 201 and the left delivery pipe 201a into the condensation box 1 to cool the condensation box 1 to improve the separation effect.

[0030] Specifically, a partition 103 is fixed to the rear wall at the middle position of the side plate 102, and the length of the partition 103 is less than the length of the internal space of the condensation box 1. The partition 103 divides the interior of the condensation box 1 into two spaces on the left and the right. The coolant flows into the internal space of the condensation box 1 on the left side of the partition 103, bypasses the partition 103 and enters the internal space of the condensation box 1 on the right side of the partition 103, so as to achieve the purpose of uniformly cooling the condensation box 1. The outside of the condensation box 1 is fixed with a sealing gasket 101 corresponding to the rear wall of the side plate 102 to prevent water droplets from leaking between the side plate 102 and the box body 2.

[0031] One end of the water inlet pipe 402 away from the heat dissipation box 4 is fixedly connected to the diverter box 201, one end of the left delivery pipe 201a away from the diverter box 201 is fixedly connected to the outer side wall of the corresponding side plate 102 on the left side of the partition 103, and one end of the right delivery pipe 202a away from the collecting box 202 is fixedly connected to the outer side wall of the corresponding side plate 102 on the right side of the partition 103. With the above arrangement, the interiors of the water inlet pipe 402 and the left delivery pipe 201a are both communicated with the interior of the water diverter box, and the interiors of the right delivery pipe 202a and the connecting pipe 301 at the liquid inlet end of the delivery pump 3 are both communicated with the interior of the collecting box 202;

[0032] The ends of the connecting pipes 301 at the liquid inlet and outlet ends of the delivery pump 3 away from the delivery pump 3 are respectively fixedly connected to the corresponding collecting box 202 and the heat dissipation box 4. The upper wall of the heat dissipation box 4 is fixed with heat dissipation fins 401 for increasing the heat dissipation area. A mounting plate 5 is arranged above the heat dissipation box 4 to provide a mounting platform for the fan 502. Connecting rods 501 are fixed at the four corners of the lower wall of the mounting plate 5, and the lower ends of the connecting rods 501 are fixedly connected to the heat dissipation box 4.

[0033] A fan 502 is fixed on the upper wall of the mounting plate 5 to generate airflow to dissipate heat from the heat dissipation box 4. A through hole 503 is provided in the middle of the mounting plate 5. When the fan 502 is working, the airflow generated passes through the through hole 503 and acts on the surface of the heat dissipation box 4. A protective net 502a is fixed on the upper wall of the fan 502 to provide protection for the fan 502. The protective net 502a can be made of metal to improve the protection performance.

[0034] The operation process of this embodiment is as follows: when in use, the steam moves in a serpentine shape from bottom to top along the gap of the condensation box 1 inside the box body 2. During the movement of the steam, the coolant after cooling the condensation box 1 enters the heat dissipation box 4 under the action of the delivery pump 3. At this time, an airflow is generated under the operation of the fan 502 to dissipate the heat of the heat dissipation box 4 after absorbing the heat of the coolant. After the heat in the coolant is absorbed, it passes through the water inlet pipe 402 and then through the diverter box 201 and the left delivery pipe 201a to enter the condensation box 1 on the left side of the partition 103, then bypasses the partition 103 and moves to the condensation box 1 on the right side of the partition 103 to absorb the heat on the surface of the condensation box 1, then passes through the collecting box 202 and the right delivery pipe 202a, and enters the heat dissipation box 4 under the action of the delivery pump 3 to dissipate heat. This cycle is used to reduce the temperature of the condensation box 1 to improve the gas-liquid separation effect. Example

[0036] Specifically, the block 102a is set in a trapezoidal shape, and the lower end of the baffle 6 is provided with an inclined surface adapted to the block 102a. The cross section of the baffle 6 is set in a rectangular shape to prevent the baffle 6 from rotating. The baffle 6 and the limit plate 604 are clearance-matched to prevent the baffle 6 from shaking. The limit plate 604 is fixedly connected to the box body 2. The upper end of the baffle 6 is fixed with an operating bar 603. By moving the operating bar 603, the corresponding baffle 6 can be moved to perform the disassembly and assembly operation of the condensation box 1.

[0038] The rest of the structure is the same as that of Example 1;
