[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0038] Combine the following Figures 1 to 4 , the spray tower and cooling dust removal system provided by the embodiment of the utility model are described in detail through specific embodiments and their application scenarios.

[0039] First, as Figure 1 and Figure 2 As shown, this embodiment provides a spray tower 1, including: a tower body 11, a spray device 12, a dust blocking assembly 13 and a cooling assembly 14.

[0040] The tower body 11 has an inner chamber 111 and an air inlet 112, an air outlet 113 and a water outlet 114 connected to the inner chamber 111; the air inlet 112 is arranged at a first end of the inner chamber 111, and the air inlet 112 is used to introduce exhaust gas, the air outlet 113 is arranged at a second end of the inner chamber 111, and the water outlet 114 is arranged at the bottom of the tower body 11.

[0041] Along the flow direction of the exhaust gas, the dust blocking assembly 13 and the cooling assembly 14 are sequentially arranged in the inner chamber 111 , and a spray device 12 is arranged between the air inlet 112 and the dust blocking assembly 13 .

[0042] After the exhaust gas is mixed with the water mist sprayed by the spray device 12, it can pass through the dust shielding component 13 and the cooling component 14 in sequence; the dust shielding component 13 is used to intercept smoke and dust in the exhaust gas, and the cooling component 14 is used to cool the exhaust gas.

[0043] It is understandable that the tower body 11 of the spray tower 1 is supported on a base, and the tower body 11 provides installation support and physical protection for the spray device 12 , the dust shielding assembly 13 and the cooling assembly 14 .

[0044] The tower body 11 of the spray tower 1 may be a stainless steel tower body 11 .

[0045] The water mist sprayed by the spray device 12 can spray the exhaust gas, remove the smoke and dust mixed in the exhaust gas, and reduce the temperature of the exhaust gas through heat exchange between the water mist and the exhaust gas. Specifically, the spray device 12 can be a nozzle and a pipe connecting the nozzle, and the spray device 12 can also be a spray arm and a spray port set on the spray arm.

[0046] The dust blocking assembly 13 allows the gas in the exhaust gas to pass through while blocking the smoke. The smoke that cannot pass through the dust blocking assembly 13 falls into the bottom of the inner chamber 111 with the water mist. The dust blocking assembly 13 may include a deflection structure, and the dust blocking assembly 13 may also include a shutter structure.

[0047] The cooling assembly 14 can reduce the temperature of the exhaust gas passing through, so that the temperature of the exhaust gas at the outlet of the exhaust port 113 is further reduced, which plays a role in protecting the service life of the equipment in the process flow after the spray tower 1.

[0048] The exhaust gas enters the inner chamber 111 from the air inlet 112, first passes through the spray device 12 for dust removal and cooling, then passes through the dust blocking component 13 for further blocking of smoke and dust, then passes through the cooling component 14 for further cooling of the exhaust gas, and finally is discharged from the exhaust port 113. The water mist sprayed from the spray device 12 settles to the bottom of the inner chamber 111 together with the smoke and dust under the action of its own gravity, and is discharged from the inner chamber 111 through the water outlet 114.

[0049] The spray tower 1 provided by the utility model is provided with a spray device 12, a dust blocking component 13 and a cooling component 14 in the tower body 11, so that the exhaust gas entering the tower body 11 from the air inlet 112 is sprayed by the spray device 12, and the sprayed water mist exchanges heat with the exhaust gas to cool the exhaust gas, and the water mist and smoke settle to the bottom of the spray tower 1 under the action of gravity, and then the exhaust gas passes through the dust blocking component 13 to further block the remaining smoke, and then the exhaust gas passes through the cooling component 14 to further reduce the temperature, so that the temperature and cleanliness of the exhaust gas discharged from the exhaust port 113 meet the requirements, so as to achieve the effect of fully cooling and removing dust from the exhaust gas.

[0050] In some embodiments, Figure 1 and Figure 2 As shown, the spray device 12 of this embodiment includes a plurality of spiral nozzles; the plurality of spiral nozzles are arranged in a spatial array in the inner chamber 111 , and the outlet end of each spiral nozzle is vertically oriented toward the dust shielding assembly 13 .

[0051] It is understandable that since the water entering the spray device 12 is recycled, the water contains smoke and dust in the exhaust gas, which can easily clog the nozzle. The spiral nozzle can allow a large amount of smoke and dust in the exhaust gas to pass through without clogging, and thus has a dust-proof effect. Moreover, since the water mist of the spiral nozzle is sprayed in a spiral shape, the projection surface of the spray is large, so that the sprayed water mist can fully exchange heat with the exhaust gas, so as to have a better cooling effect on the exhaust gas. At the same time, the spiral nozzle adopts impact-type dispersed spray, and the water flow realizes layered spraying by impacting the layered interface of the spiral, and the contact area with the exhaust gas is large, thereby producing a good dust removal effect.

[0052] In this embodiment, multiple spiral nozzles are arranged in a spatial array in the inner chamber 111, so that the space between the air inlet 112 of the inner chamber 111 and the dust shield assembly 13 is highly filled. The water mist sprayed by the multiple spiral nozzles fills the surrounding space, so that the exhaust gas and the water mist in the inner chamber can be highly mixed, which is beneficial to better heat exchange and dust absorption between the exhaust gas and the water mist, so as to achieve better dust removal and cooling effects. At the same time, the outlet end of each spiral nozzle is perpendicular to the dust shield assembly 13, so that the exhaust gas and the water mist can be easily close to the dust shield assembly 13 after mixing, which is beneficial for the exhaust gas to quickly pass through the dust shield assembly 13 and improve the cooling efficiency.

[0053] In some embodiments, Figure 1 As shown, a spray device 12 is further provided between the dust shielding assembly 13 and the cooling assembly 14 in this embodiment.

[0054] It is understandable that a spray device 12 is arranged between the dust blocking component 13 and the cooling component 14, so that when the exhaust gas passes through the dust blocking component 13 to block the smoke and dust, and when the exhaust gas passes through the cooling component 14 to be cooled, an operation of cooling and removing dust from the exhaust gas is added. The exhaust gas sprayed by the spray device 12 and blocked by the dust blocking component 13 is then sprayed by the spray device 12 once more, which can ensure that the temperature of the exhaust gas is continuously reduced, and the smoke and dust in the exhaust gas is further reduced, thereby enhancing the effect of cooling and removing dust from the exhaust gas.

[0055] In some embodiments, Figure 1 As shown, the dust shielding assembly 13 of this embodiment includes a plurality of baffles.

[0056] A plurality of baffles are arranged side by side, and two adjacent baffles define a baffle channel in the inner chamber 111 , and the baffle channel is used to guide the exhaust gas from the side of the dust shield assembly 13 toward the spray device 12 to the side away from the spray device 12 .

[0057] It can be understood that the baffle is formed by repeatedly bending a stainless steel plate, and the baffle channel formed between two adjacent baffles also has a repeatedly bent channel, so that the exhaust gas can change its flow direction when passing through the baffle channel, and the smoke and dust in the exhaust gas is blocked by the baffle and settles to the bottom of the inner chamber 111 with the water mist. In this way, the smoke and dust in the exhaust gas passing through the baffle is blocked and separated from the exhaust gas, and the exhaust gas flows through the baffle to the side of the dust blocking assembly 13 away from the spray device 12.

[0058] This embodiment arranges a plurality of baffles side by side in the dust shielding assembly 13, thereby allowing the exhaust gas to pass through while blocking the smoke and dust in the exhaust gas, thereby further enhancing the dust removal effect.

[0059] In some embodiments, Figure 1 As shown, the cooling assembly 14 of this embodiment includes a mesh support and a plurality of ball rings.

[0060] The mesh support is arranged in the inner chamber 111, and a plurality of ball rings are arranged in the mesh support.

[0061] It is understandable that the ball ring contains many small gaps and grooves, so that when the exhaust gas passes through the ball ring, there are many contact surfaces between the exhaust gas and the ball ring. Each surface of the ball ring forms a water film with the exhaust gas, which can quickly cool down the exhaust gas.

[0062] Furthermore, multiple ball rings are stacked in the mesh bracket to form a three-dimensional mesh structure, so that when the exhaust gas passes through the multiple ball rings in the mesh bracket, it is cooled in an all-round, three-dimensional and multi-level manner, which is beneficial to enhance the cooling of the exhaust gas.

[0063] In some embodiments, Figure 1 As shown, the shell wall of the tower body 11 of this embodiment is provided with an inspection port, which is communicated with the inner chamber 111. The inspection port is provided with an inspection door 115, and the inspection door 115 has a first state of opening the inspection port and a second state of closing the inspection port.

[0064] It is understandable that if the spray device 12, the dust shield assembly 13 and the cooling assembly 14 are blocked or damaged during operation and need to be repaired or replaced, the inspection port provided on the shell wall of the tower body 11 provides a passage for entering and exiting the spray tower 1. During the maintenance of the spray tower 1, the operator opens the inspection door 115 and enters the inner chamber 111 from the inspection port to perform operations. During the operation of the spray tower 1, the inspection door 115 is in a closed state and does not affect the normal operation of the spray tower 1. The inspection door 115 of this embodiment can ensure that the spray tower 1 has a set passage to enter and exit the inner chamber 111 to meet the needs of maintenance and debugging.

[0065] In some embodiments, Figure 1 As shown, the spray tower 1 of this embodiment further includes a demisting net 15 .

[0066] The demisting net 15 is disposed between the cooling assembly 14 and the exhaust port 113 .

[0067] It is understandable that the demisting net 15 is used to block and intercept water mist in the exhaust gas so that the water mist content in the exhaust gas discharged from the exhaust port 113 is reduced to within the standard value, making the humidity of the exhaust gas very small, thereby ensuring that the exhaust gas will not cause damage to downstream process equipment.

[0068] Specifically, the demisting net 15 of this embodiment adopts a modular design, and multiple small demisting nets 15 are installed on a frame, and the frame is arranged in the inner chamber 111, so that when the demisting net 15 is blocked, only the local demisting net can be disassembled and replaced, avoiding the difficulty of overall operation of a whole demisting net 15.

[0069] In some embodiments, differential pressure transmitters are provided at both ends of the demisting net 15 of this embodiment, and the differential pressure transmitter is used to detect the air pressure difference between the side of the demisting net 15 facing the cooling component 14 and the side away from the cooling component 14.

[0070] It is understandable that the differential pressure transmitter is used to measure the pressure difference of the exhaust gas at the front and rear ends of the defogger 15. When the defogger 15 is blocked by smoke in the exhaust gas, the pressure difference of the exhaust gas at the front and rear ends of the defogger 15 is very large. At this time, it is displayed through the differential pressure display connected to the differential pressure transmitter, providing the operator with information on the need to clean or replace the defogger 15.

[0071] This embodiment is provided with a differential pressure transmitter, so as to detect the working state of the demisting net 15 in real time, and provide timely feedback when the demisting net 15 is blocked, thereby ensuring the normal operation of the demisting net 15.

[0072] In some embodiments, Figure 1 and Figure 3 As shown, the air inlet 112 of this embodiment is provided with a flow guide assembly 16 .

[0073] The flow guide assembly 16 includes a plurality of blades, which are disposed on the inner wall of the air inlet 112 and arranged along the circumference of the air inlet 112 .

[0074] It is understandable that the guide component 16 is used to improve the uniformity of the flow field in the spray tower 1, so that the exhaust gas entering the spray tower 1 from the air inlet 112 can be better mixed with the water mist sprayed by the spray device 12, thereby ensuring the cooling and dust removal efficiency.

[0075] This embodiment uses multiple blades to guide the exhaust gas. Through the guiding and disturbing effect of the blades on the exhaust gas, the exhaust gas is disturbed more after entering the air inlet 112, which promotes strong mixing of the exhaust gas and the water mist sprayed by the spray device 12, which is beneficial to the cooling and dust removal effect.

[0076] In a second aspect, in some embodiments, as Figure 4 As shown, this embodiment provides a cooling dust removal system, including a water tank 2, a water pump 3 and a spray tower 1.

[0077] The water tank 2 is used to store cooling water. The water tank 2 is connected to the inlet end of the water pump 3 . The outlet end of the water pump 3 is connected to the spray device 12 . The water outlet 114 of the spray tower 1 is connected to the water tank 2 .

[0078] Specifically, since the cooling and dust removal system includes a spray tower 1, and the specific structure of the spray tower 1 refers to the above embodiment, the cooling and dust removal system shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0079] It is understandable that the exhaust gas generated by the jet tube type heating and humidifying machine contains smoke and dust, and has high temperature, humidity and flow rate.

[0080] The cooling water used in this embodiment is tap water, and the cooling water can be recycled. No acid, alkali, or salt chemicals are added to the water. There is no need to drain the cooling water during use, so that the cooling water is not polluted again. For the re-cooling of the cooling water, a cooling fan can be used to force the water in the water tank 2 to cool it, so that the cooling water that has absorbed the heat of the exhaust gas can be quickly cooled for easy recycling.

[0081] After the water mist and exhaust gas of the spray device 12 in the spray tower 1 are mixed, the water mist and smoke settle to the bottom of the spray tower 1, and the cooling water and smoke that have absorbed the heat of the exhaust gas flow back to the water tank 2 from the water outlet 114 through the pipeline, and the smoke is deposited at the bottom of the water tank 2. The cooling water cooled by the cooling fan is transported to the spray device 12 in the spray tower 1 along the delivery pipeline under the suction action of the water pump 3.

[0082] This embodiment provides a water tank 2, a water pump 3 and a spray tower 1 so that the cooling water can be recycled during the cooling and dust removal process of the exhaust gas, which not only achieves a better cooling and dust removal effect, but also facilitates the recycling of cooling water, thereby enhancing the economy of the exhaust gas treatment.

[0083] In some embodiments, Figure 4 As shown, the cooling and dust removal system of this embodiment further includes: an adsorption tower 4 and an induced draft fan 5.

[0084] The input end of the induced draft fan 5 is connected to the exhaust port 113 of the spray tower 1, and the induced draft fan 5 is used to suck the waste gas treated by the spray tower 1; the output end of the induced draft fan 5 is connected to the adsorption tower 4, and the adsorption tower 4 is used to adsorb the waste gas.

[0085] It is understandable that the adsorption treatment of exhaust gas is to remove odorous gases containing flavors and fragrances, and an adsorption bag made of activated carbon fiber is provided in the adsorption tower 4 as an adsorbent. The activated carbon fiber has a fast adsorption speed and high adsorption efficiency for odorous gas molecules. The odor removal efficiency of activated carbon fiber can reach 95%.

[0086] The waste gas is discharged from the exhaust port 113 of the spray tower 1 and is sucked into the adsorption tower 4 by the induced draft fan 5. The waste gas containing odor is adsorbed and intercepted by the activated carbon fiber, and the waste gas without odor is discharged into the atmosphere under the suction action of the induced draft fan 5. The adsorption tower 4 of this embodiment can ensure that the odor gas molecules in the waste gas are adsorbed, thereby achieving the effect of further purifying the waste gas.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
