Description

Technical Field

[0001] The utility model belongs to the technical field of operation and relates to a dust removal device, in particular to a water mist monitoring device for a wet dust collector. Background Art

[0002] Wet dust removal is a method of purifying the gas by fully contacting the scrubbing liquid (usually water) with the dust-containing gas to wash away the dust particles. Wet dust removal is highly efficient, the wet dust collector has a simple structure, low cost, small footprint, and is easy to operate and maintain. It is particularly suitable for handling high-temperature, high-humidity, flammable, and explosive dust-containing gases. Existing wet dust collectors generally use a fan in conjunction with the liquid in the dust collector to adsorb dust using the generated water mist. This method requires a monitoring device to be set at the bottom liquid level of the dust collector to monitor the liquid level. If the liquid level is not high enough, the air gap will become larger, affecting the amount of water mist and the dust removal effect. However, when the monitoring device monitors the bottom liquid level of the dust collector, it is easily affected by the wind force and air pressure of the fan. When the liquid level shakes, it greatly affects the monitoring accuracy. It is difficult to determine whether the water mist content in the dust removal area meets the requirements, and there are many interference factors.

[0003] To this end, the Chinese patent discloses a self-excited wet dust collector with application number 202320171881.8, which includes a fan and a shell with a dust removal chamber and a dust collection chamber, the bottom of the dust removal chamber is connected to the bottom of the dust collection chamber and a water vapor separation member is arranged in the dust removal chamber, characterized in that a water collecting member is fixed in the dust removal chamber, the water collecting member has a roughly tubular body and a water inlet connected to the upper end of the body, the flow cross-sectional area of ​​the water collecting member at the water inlet is greater than the flow cross-sectional area of ​​the water collecting member at the connection between the water inlet and the body, and the self-excited wet dust collector also includes a sensor that can detect the water pressure in the body and an alarm that can alarm when the value detected by the sensor is less than the set value. However, in the actual monitoring process of this scheme, the monitored liquid level height is still easily affected by the wind force and air pressure of the fan, and the liquid level shakes, which greatly affects the monitoring accuracy. It is difficult to judge whether the water mist content in the dust removal area meets the requirements. There are many interference factors and the monitoring accuracy is poor.

DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings.

[0030] like Figure 1-3 As shown, a water mist monitoring device for a wet dust collector is provided. The wet dust collector comprises a shell 1 having an inner cavity. The shell 1 comprises an outer shell 1a having an inner cavity, a partition 2 and a water storage tank 3 arranged in the outer shell 1a. The area in the inner cavity of the outer shell 1a located in front of the partition 2 is a dust intake area 1b, the area in the inner cavity of the outer shell 1a located in the rear of the partition 2 is a dust removal area 1c, and the bottom of the inner cavity of the outer shell 1a is a water storage area 1d. When water is contained in the water storage area 1d, the partition 2 is disposed in the outer shell 1a. A wind gap 1e is formed between the bottom edge of the dust removal area 1c and the liquid surface of the water storage area 1d; a plurality of staggered separation inclined plates 4 are arranged from top to bottom in the dust removal area 1c, and the separation inclined plate 4 located at the bottom is called the first separation inclined plate 4a. The water storage tank 3 is located in the dust removal area 1c and below the first separation inclined plate 4a, and the water separated by the separation inclined plate 4 can enter the water storage tank 3; the wet dust collector also includes a drainage structure that can drain the water in the water storage tank 3 to the wind gap 1e;

[0031] The water mist monitoring device is characterized in that it comprises a water accumulation tray 5 located between the first separation inclined plate 4a and the water storage tank 3 and a water flow electronic sensor 6 located outside the shell 1, the water accumulation tray 5 is connected to the shell 1 and / or the first separation inclined plate 4a through a fixed installation structure; the water flow electronic sensor 6 is located below the water accumulation tray 5, the inner cavity of the water accumulation tray 5 is connected to the water flow electronic sensor 6 through a pipeline, and the water discharged from the water flow electronic sensor 6 enters the water storage area 1d;

[0032] The water mist monitoring device also includes a control circuit, and the water flow electronic sensor 6 is electrically connected to the control circuit. The control circuit is set with a water flow alarm threshold, and when the water flow value monitored by the water flow electronic sensor 6 is lower than the water flow alarm threshold, the control circuit sends an alarm signal.

[0033] In this embodiment, the rear part of the inner cavity of the outer shell 1a is called the air outlet area 1h, and the top surface of the air outlet area 1g in the outer shell 1a is provided with an air outlet 1i. The air outlet 1i can be connected to the fan through a pipeline, or the fan connected to the outlet air 1f can be directly fixed on the top plate of the outer shell 1a. During use, the fan is started, and the dust generated by polishing hits the side of the partition 2. The washing liquid in the water holding area 1d flows downward from the plate surface of the partition 2 on the side of the dust inlet area 1b, which effectively increases the possibility of mixing between the dust and the washing liquid, thereby improving the dust removal efficiency. The water mist carries the dust to form an airflow, enters from the wind gap 1e, and then flows in a circuitous manner along the separation inclined plate 4. The water mist collides with the first separation inclined plate 4a, and then the water mist loses kinetic energy and condenses on the surface of the first separation inclined plate 4a. After the condensation amount of the water mist increases, it naturally flows downward under the action of gravity, and part of it accumulates in the water accumulation tray 5, part of it accumulates in the water storage tank 3, and the liquid in the water storage tank 3 flows back to the water holding area 1d through the drainage structure. The water flow electronic sensor 6 is used to monitor the water flow in the water storage tray 5. When the water flow value monitored by the water flow electronic sensor 6 is lower than the water flow alarm threshold, the control circuit sends an alarm signal. The water storage tray 5 is arranged below the first separation inclined plate 4a, which is not only easy to receive the water required for monitoring, but also the water receiving amount of the water storage tray 5 and the total amount of water separated by the separation inclined plate 4a have a relatively stable ratio. By monitoring whether the amount of water flowing out of the water storage tray reaches the set threshold, the amount of water entering the water storage tank 3 and the amount of water drained to the wind gap 1e can be determined, and then it can be determined whether the water mist content in the dust removal area 1c meets the requirements; the water storage tray 5 is in the shape of a disk, which not only increases the amount of water received, but also reduces the height of the water storage tray 5, thereby reducing the adverse effect of the water storage tray 5 on the air flow;

[0034] The drainage structure may be optionally provided with a drain port at the water storage tank 3 to allow the liquid to flow downward along the side of the partition, or a pipeline that can return the liquid to the water storage area 1d or other drainage structure that can return the liquid in the water storage tank 3 to the water storage area 1d may be connected to the bottom of the water storage tank 3.

[0035] Combined diagram Figure 1-3 As shown, the side wall of the water collection tray 5 close to the lower edge of the first separation inclined plate 4a is called the first side wall, and a wind shield 5a is arranged between the water collection tray 5 and the first separation inclined plate 4a. The upper edge of the wind shield 5a is in contact with or sealedly connected to the lower side surface of the first separation inclined plate 4a, and the lower edge of the wind shield 5a is sealedly connected to or in contact with the first side wall.

[0036] Specifically, by providing the wind shield 5a, not only the influence of the airflow on the water in the water collection tray 5 is reduced, that is, the possibility of the water in the water collection tray 5 being blown away by the airflow is reduced, thereby lowering the height of the water collection tray 5; by providing the wind shield 5, it is also beneficial for the water separated by the first separation inclined plate 4a to enter the water collection tray 5, thereby reducing the area of ​​the water collection tray 5.

[0037] Combined diagram Figure 1 , Figure 2 As shown, the wind shield 5a is integrally connected to the first side wall, and the upper edge of the wind shield 5a is in contact with the lower side of the first separation inclined plate 4a;

[0038] Or the upper edge of the windshield plate 5a is sealed and fixedly connected to the lower side of the first separation inclined plate 4a, and the lower edge of the windshield plate 5a is in contact with the side of the first side wall;

[0039] Or the upper edge of the windshield 5a is sealed and fixedly connected to the lower side of the first separation inclined plate 4a, and the windshield 5a is integrally connected to the first side wall;

[0040] The side wall of the water accumulation tray 5 away from the lower edge of the first separation inclined plate 4a is called the second side wall. A fixed hook bar 5b is provided between the water accumulation tray 5 and the first separation inclined plate 4a. The upper edge of the fixed hook bar 5b is in contact with or sealed with the lower side of the first separation inclined plate 4a, and the lower edge of the fixed hook bar 5b is connected to the second side wall.

[0041] The upper edge of the fixed hook strip 5b is sealed and fixedly connected to the lower side of the first separation inclined plate 4a, and the lower edge of the fixed hook strip 5b is in contact with the side of the second side wall;

[0042] Or the upper edge of the fixed hook strip 5b is sealed and fixedly connected to the lower side surface of the first separation inclined plate 4a, and the fixed hook strip 5b is connected to the second side wall as a whole.

[0043] In this embodiment, the upper edge of the wind shield 5a and the upper edge of the fixed hook strip 5b can be fixed to the lower side surface of the first separation inclined plate 4a by welding or a screw and bolt structure, and the lower edge of the wind shield 5a and the lower edge of the fixed hook strip 5b can be hook-shaped to hook and support the water collection tray 5, making it convenient to disassemble the water collection tray 5.

[0044] A manipulation port 1f is provided on the front side wall of the dust inlet area 1b, and a polishing wheel 7 is provided in the dust inlet area 1b.

[0045] In this embodiment, after the polishing wheel 7 is working, the dust generated by polishing is directly gathered in the dust inlet area 1b. When the fan is started, the air in the dust collector is quickly discharged to prevent the dust generated by polishing from spreading. At the same time, part of the dust naturally settles on the liquid surface, so that the dust inlet area 1b has the function of a dust collecting hood, and the structure is compact and reasonable.

[0046] Combined diagram Figure 1 , Figure 3 As shown, a dust cleaning port 1g is provided at the rear side of the outer shell 1a, and a rear wall plate 8 which can extend into the water storage area 1d is fixedly connected to the rear side wall of the outer shell 1a.

[0047] In this embodiment, a dust cleaning port 1g is provided at the rear side of the outer shell 1a. In order to prevent airflow from entering the inner cavity from the dust cleaning port 1g, the rear wall plate 8 plays a role of windproofing to prevent liquid level fluctuations.

[0048] Combination Figure 1-2 As shown, a water retaining strip 4b is fixed to the lower plate surface of the separation inclined plate 4, and the length of the side wall of the water accumulation tray 5 is less than the length of the first separation inclined plate 4a.

[0049] In this embodiment, the water retaining strip 4b can improve the water mist separation rate of the separation inclined plate 4 and reduce the water loss. The water retaining strip 4b can also improve the strength of the separation inclined plate 4, reduce vibration, and thus reduce noise. The width of the water accumulation tray 5 is smaller than the width of the first separation inclined plate 4a, ensuring that part of the liquid accumulates in the water accumulation tray 5 and part accumulates in the water storage tank 3. The liquid in the water storage tank 3 flows back to the water holding area 1d through the drainage structure. The amount of water entering the water storage tank 3 is greater than the amount of water entering the water accumulation tray 5. If the water flow in the water accumulation tray 5 is sufficient, the water flow in the water storage tank 3 is also sufficient, which can ensure that the liquid level height in the water holding area 1d meets the requirements.

[0050] The working principle of the utility model is:

[0051] The rear part of the inner cavity of the outer shell 1a is called the air outlet area 1h. The top surface of the air outlet area 1g in the outer shell 1a is provided with an air outlet 1i. The air outlet 1i can be connected to the fan through a pipeline, or the fan connected to the outlet air 1f can be directly fixed on the top plate of the outer shell 1a. During use, the fan is started, and the dust generated by polishing hits the side of the partition 2. The washing liquid in the water holding area 1d flows downward from the plate surface of the partition 2 on the side of the dust inlet area 1b, which effectively increases the possibility of mixing between the dust and the washing liquid, thereby improving the dust removal efficiency. The water mist carries the dust to form an air flow, enters from the wind gap 1e, and then flows in a circuitous manner along the separation inclined plate 4. The water mist collides with the first separation inclined plate 4a, and then the water mist loses kinetic energy and condenses on the surface of the first separation inclined plate 4a. After the condensation amount of the water mist increases, it naturally flows downward under the action of gravity, and part of it accumulates in the water accumulation tray 5, and part of it is The liquid in the water storage tank 3 flows back to the water holding area 1d through the drainage structure. The water flow electronic sensor 6 is used to monitor the water flow in the water storage tray 5. When the water flow value monitored by the water flow electronic sensor 6 is lower than the water flow alarm threshold, the control circuit sends an alarm signal. The water storage tray 5 is arranged below the first separation inclined plate 4a. It is not only easy to receive the water required for monitoring, but also the water receiving amount of the water storage tray 5 and the total amount of water separated by the separation inclined plate 4a have a relatively stable ratio. By monitoring whether the amount of water flowing out of the water storage tray reaches the set threshold, the amount of water entering the water storage tank 3 and the amount of water drained to the wind gap 1e can be determined, and then it can be determined whether the water mist content in the dust removal area 1c meets the requirements; the water storage tray 5 is in the shape of a disk, which not only increases the amount of water received, but also reduces the height of the water storage tray 5, thereby reducing the adverse effect of the water storage tray 5 on the airflow.

[0052] The provision of the wind shield 5a not only reduces the influence of the airflow on the water in the water collection pan 5, that is, reduces the possibility of the water in the water collection pan 5 being blown away by the airflow, thereby reducing the height of the water collection pan 5; the provision of the wind shield 5 also facilitates the water separated by the first separation inclined plate 4a to enter the water collection pan 5, thereby reducing the area of ​​the water collection pan 5.

[0054] After the polishing wheel 7 works, the dust generated by polishing is directly collected in the dust inlet area 1b. When the fan is started, the air in the dust collector is quickly discharged to prevent the dust generated by polishing from spreading. At the same time, part of the dust naturally settles on the liquid surface, so that the dust inlet area 1b has the function of a dust collection hood, and the structure is compact and reasonable.

[0055] A dust cleaning port 1g is provided at the rear side of the outer shell 1a. In order to prevent airflow from entering the inner cavity through the dust cleaning port 1g, the rear wall plate 8 plays a role of windproof and avoids fluctuations in the liquid level.

[0056] The water strip 4b can improve the water mist separation rate of the separation inclined plate 4 and reduce the water loss. The water retaining strip 4b can also improve the strength of the separation inclined plate 4, reduce vibration, and thus reduce noise. The width of the water accumulation tray 5 is smaller than the width of the first separation inclined plate 4a, ensuring that part of the liquid accumulates in the water accumulation tray 5 and part accumulates in the water storage tank 3. The liquid in the water storage tank 3 flows back to the water holding area 1d through the drainage structure. The amount of water entering the water storage tank 3 is greater than the amount of water entering the water accumulation tray 5. If the water flow in the water accumulation tray 5 is sufficient, the water flow in the water storage tank 3 is also sufficient, which can ensure that the liquid level height in the water holding area 1d meets the requirements.
