Description

Technical Field

[0001] The utility model relates to the technical field of dust removal and demisting, in particular to a tube bundle type double-ring high-efficiency dust removal and demisting device. Background Art

[0002] The tube bundle dust and mist collector is a gas-liquid separator based on centrifugal separation. It uses the centrifugal effect of the rotating airflow to throw the droplets entrained in the airflow to the surrounding wall surface. The tiny droplets, fine dust particles, aerosols and other tiny particles in the flue gas collide with each other, agglomerate and condense into large droplets, which are then captured by the liquid film on the surface of the cyclone tube, thereby being separated from the gas phase and removed. It has the advantages of small pressure drop, good demisting effect, simple structure, and simple transformation and implementation.

[0003] When the tube bundle dust collector and demister is treating saturated flue gas, a thick liquid film is formed on the inner wall of the pipe under the action of the centrifugal force provided in the tube bundle dust collector and demister, causing secondary carryover and affecting the efficiency of the integrated tube bundle dust collector and demister. Utility Model Content

[0004] The utility model aims to provide a tube bundle type double-ring high-efficiency dust and mist remover to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tube bundle type double-ring high-efficiency dust and mist remover comprises a tube body, a rotator is arranged inside the tube body, a primary filter assembly is arranged on the lower side of the rotator, and the primary filter assembly comprises a plurality of annular guide plates, each guide plate is bent in the length direction, both ends of each guide plate are fixedly connected to a plurality of fixing strips, each of the fixing strips is fixedly connected to a central axis, and the outermost guide plate is fixedly connected to the inner wall of the tube body.

[0007] Furthermore, it also includes a condensation mechanism, which includes a plurality of condensation covers fixedly connected to the fixing strips, each of the condensation covers is spaced apart at both ends of the guide plate, and the adjacent guide plates connected to the condensation covers at both ends and the two condensation covers together form a condensation channel, and each of the condensation covers is connected to a ventilation assembly to introduce cooling air into the condensation channel.

[0008] Furthermore, the adjacent guide plates whose two ends are not connected to the condensation cover form a condensation channel.

[0009] Furthermore, the ventilation assembly includes an air cooler, the air inlet and outlet of the air cooler are respectively connected to connecting pipes, the connecting pipes pass through the pipe body and are both connected to the central axis, air flow channels are opened in the central axis and the fixed bar, and the air flow channels are respectively connected to the connecting pipes and the condensation channel.

[0010] Furthermore, the flow direction of the cooling gas is opposite to the flow direction of the flue gas.

[0011] In the above technical solution, the utility model provides a tube bundle type double ring high efficiency dust and mist remover with the beneficial effects of:

[0012] Through the set primary condensation component, the flue gas first enters the primary filtration component from the lower side of the tube body, and the adjacent guide plates form a tortuous channel, which changes the flow velocity and direction of the flue gas, and the flow trajectory constantly deflects and turns sharply. Due to their high density, droplets and fine particles have poor followability to the flue gas, and they constantly collide with the guide plates under the action of inertia, so that the droplets and fine particles complete the initial separation from the flue gas, effectively reducing the content of droplets and particles in the flue gas, and are further separated under the action of the rotator, avoiding the secondary carryover problem caused by highly saturated flue gas passing directly through the rotator.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] See also Figure 1-4 A bundle-type double-ring high-efficiency dust and mist remover includes a tube body 1, a rotator 11 is provided in the tube body 1, a primary filter assembly is provided in the tube body 1, the primary filter assembly is arranged at the lower side of the rotator 11, and the primary filter assembly includes a plurality of annular guide plates 21, each of which is bent in the length direction, and both ends of each guide plate 21 are fixedly connected to a plurality of fixing bars 22, each of which is fixedly connected to a central axis 23, and the outermost guide plate 21 is fixedly connected to the inner wall of the tube body 1. The portion of the tube body 1 fixedly connected to the guide plate 21 has the same bending degree as the guide plate 21, so as to prevent smoke from passing through the gap between the two.

[0024] Through the initial condensation component, the flue gas first enters the primary filtration component from the lower side of the tube body 1, and the adjacent guide plates 21 form a tortuous channel, which changes the flow velocity and direction of the flue gas, and the flow trajectory constantly deflects and turns sharply. Due to their high density, the droplets and fine particles have poor followability to the flue gas, and they constantly collide with the guide plates 21 under the action of inertia, so that the droplets and fine particles remain on the guide plates 21, completing the initial separation from the flue gas, effectively reducing the content of droplets and particles in the flue gas, and further separated under the action of the rotator 11, avoiding the secondary carryover problem caused by the highly saturated flue gas directly passing through the rotator 11.

[0025] In the embodiment further provided by the present invention, a condensation mechanism is further included, the condensation mechanism includes a plurality of condensation covers 3 fixedly connected to the fixing strip 22, each of the condensation covers 3 is arranged at intervals at both ends of the guide plate 21, the adjacent guide plates 21 connected to the condensation covers 3 at both ends and the two condensation covers 3 together form a condensation channel 31, each of the condensation covers 3 is connected to a ventilation assembly to pass cooling air into the condensation channel 31. The adjacent guide plates 21 not connected to the condensation covers 3 at both ends form a condensation channel 32.

[0026] The ventilation component introduces cooling gas into the condensation channel 31, and the cooling gas cools the flue gas in the adjacent ice condensation channel by heat conduction. The water vapor in the saturated flue gas condenses into water and condenses with the fine particles carried in the flue gas on the guide plate 21, thereby further improving the gas-liquid separation effect of the primary filter component.

[0027] In an embodiment further provided by the utility model, the ventilation assembly includes an air cooler 4, the air inlet and the air outlet of the air cooler 4 are respectively connected with a connecting pipe 41, the connecting pipe 41 passes through the pipe body 1 and is connected to the central axis 23, and an air flow channel 42 is opened in the central axis 23 and the fixing bar 22, and the air flow channel 42 is respectively connected with the connecting pipe 41 and the condensation channel 31. The flow direction of the cooling air is opposite to that of the flue gas.

[0028] The cooling air generated by the air cooler enters the condensation channel 31 through the connecting pipe 41 and the airflow channel 42 in turn, and cools the flue gas in the adjacent condensation channel 32. Since the cooling air and the flue gas flow in opposite directions, the flue gas is always in contact with the unheated cooling air during the movement of the condensation channel 32, further enhancing the cooling effect of the cooling air on the flue gas, thereby improving the dust removal and demisting effect of the primary filter component; and after passing through the condensation channel 31, the cooling air returns to the air cooler through the airflow channel 42 and the connecting pipe 41 in turn, thereby realizing the recycling of the cooling air.

[0029] Working principle:

[0030] The cooling air generated by the air cooler enters the condensation channel 31 through the connecting pipe 41 and the air flow channel 42 in turn, cools the flue gas in the adjacent condensation channel 32, and the water vapor in the saturated flue gas condenses into water, and condenses with the fine particles carried in the flue gas on the guide plate 21, thereby further improving the gas-liquid separation effect of the primary filter component; and because the cooling air and the flue gas flow in opposite directions, the flue gas is always in contact with the unheated cooling air during the movement of the condensation channel 32, further improving the cooling effect of the cooling air on the flue gas, so as to improve the dust removal and demisting effect of the primary filter component; in addition, due to the bending setting of the guide plate 21, the flue gas continuously changes its flow velocity and flow direction in the condensation channel 32, and the flow trajectory continuously deflects and turns sharply. Due to their high density, the droplets and fine particles have poor followability to the flue gas, and continuously collide with the guide plate 21 under the action of inertia, so that the droplets and fine particles remain on the guide plate 21, which also improves the demisting and dust removal effect of the device.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
