Description

Technical Field

[0001] The utility model relates to the technical field of organic waste gas treatment, in particular to a waste gas treatment device for a single-row tube brazing furnace. Background Art

[0002] Direct air cooling technology is widely used in the field of exhaust steam cooling. The condenser tube bundle is the core component of the direct air cooling system. Single-row tubes have become the mainstream tube type for direct air cooling due to their high heat transfer coefficient, low wind resistance, and excellent antifreeze performance.

[0003] The single-row tube is composed of serpentine fins (made of aluminum foil) and rectangular flat tubes (made of aluminum-clad steel plates). The serpentine fins are formed by aluminum foil through a belt folding machine. To ensure that the surface of the fins is smooth and scratch-free after processing, the aluminum foil needs to be sprayed with lubricating oil during processing. The boiling point of the fin lubricating oil is about 230°C and it is insoluble in water. When the fins are heated in the drying section of the brazing furnace, the lubricating oil evaporates or (and) thermally decomposes, which will produce harmful and flammable organic gases.

[0004] The treatment of organic waste gas is crucial to the prevention and control of air pollution, and it must be discharged in strict accordance with the prescribed standards. The waste gas treatment device includes all waste gas treatment equipment between the organic waste gas collection pipe and the exhaust pipe. Conventional organic waste gas treatment processes include adsorption method, thermal oxidation method, etc.

[0005] The process flow of the adsorption method: the organic waste gas first passes through the PP (polypropylene) spray tower for water bath, and then passes through the activated carbon box for adsorption. The PP spray tower adopts a gas-liquid two-phase flow contact method to remove the dust content of the organic waste gas and absorb part of the heat of the organic waste gas. The activated carbon box uses the porosity of activated carbon and has a large surface area; at the same time, there are unbalanced and unsaturated molecular attraction or chemical bond force on the surface of the activated carbon, which has strong adsorption, so that the organic matter in the organic waste gas is adsorbed on the surface of the activated carbon to achieve the purpose of purification. The demister at the top of the PP spray tower operates at high temperature for a long time, and the dehumidification effect will be weakened, resulting in an increase in the moisture content of the organic waste gas and accelerating the failure process of the activated carbon adsorption capacity. With this process route, the activated carbon has a short service life and a high replacement frequency. At the same time, the activated carbon box equipment has a large resistance, and the motor selection of the matching fan has a large power and high operating power consumption, which increases the primary investment and operating costs.

[0006] Organic gas is a volatile substance and is easy to burn. The process flow of thermal oxidation method: In the gas incinerator, the organic waste gas is first preheated, and then incinerated with the assistance of a combustion aid (such as natural gas) to make it harmless. With this process route, the one-time investment and operating cost of the waste gas treatment device are too high.

[0007] In order to overcome the weaknesses of the prior art, the present application provides a single-row tube brazing furnace exhaust gas treatment device, which utilizes the principle that the distillation temperature of lubricating oil and its thermal decomposition products is relatively low (the distillation temperature range is 40 to 230°C) to cool the organic exhaust gas, recover the condensed oil, and ensure that the purified exhaust gas meets the emission standards.

[0008] Therefore, how to provide a single-row tube brazing furnace exhaust gas treatment device with low energy consumption and low cost is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

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.

[0039] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation of the present invention.

[0041] The utility model aims to provide a single-row tube brazing furnace waste gas treatment device, which can discharge purified waste gas in compliance with the standards, reduce energy consumption and the cost required for treating organic waste gas.

[0042] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0043] See also Figures 1 to 3 The present embodiment provides a single-row tube brazing furnace waste gas treatment device, including: a blowing component 100, a spray tower 200, a cooler 400 and a cooling tower 600; the blowing component 100 is used to transport organic waste gas; the spray tower 200 is connected to the blowing component 100 through a collecting pipe 210, and is used to remove dust and cool the organic waste gas passing through; the cooler 400 is connected to the spray tower 200 through an air duct 300, and is provided with a heat exchange tube bundle 500 inside. The heat exchange tube bundle 500 can cool the organic waste gas in the cooler 400 to liquid to form condensed oil. The condensed oil can be collected at the bottom of the cooler 400, and the purified waste gas can also be discharged; the cooling tower 600 is connected to the heat exchange tube bundle 500 and is used to provide continuous low-temperature water.

[0044] Specifically, the blowing component 100 in this embodiment is preferably a blower, and the single-row tube brazing furnace exhaust gas treatment device can blow the organic waste gas gathered in the collecting pipe 210 into the spray tower 200 through the blower for treatment; the spray tower 200 in this embodiment is specifically a PP (polypropylene) spray tower 200, and the organic waste gas can enter the cooler 400 through the air duct 300 after being treated in the spray tower 200. According to the principle that the distillation temperature of the lubricating oil and its thermal decomposition products is relatively low, the organic waste gas is cooled and treated, so that the lubricating oil and its thermal decomposition products are condensed into liquid and recovered, and the heat exchange tube bundle 500 plays a cooling role, and cooling water circulates inside the heat exchange tube bundle 500, and the cooling tower 600 provides low-temperature water for the heat exchange tube bundle 500.

[0045] That is to say, the organic waste gas first gathers in the collecting pipe 210 and is blown into the water bath of the spray tower 200 through a blower to remove the dust content of the organic waste gas and absorb part of the heat of the organic waste gas; then it passes through the air duct 300 and enters the organic waste gas cooler 400 for heat exchange through the heat exchange tube bundle 500, so that the lubricating oil and its thermal decomposition products are condensed into liquid, and then the purified waste gas is discharged, thereby achieving the purpose of purifying the organic waste gas; in this way, compared with the traditional process route, the single-row tube brazing furnace waste gas treatment device provided by the utility model reduces the one-time investment and saves operating energy consumption. At the same time, it is flexible to adjust, easy to operate and maintain, and can also ensure that the emission standards are met.

[0046] Preferably, the blowing component 100 is disposed at the bottom of the spray tower 200 , and the air duct 300 is connected to the top of the spray tower 200 and the top of the cooler 400 .

[0047] It can be understood that the blowing component 100 is arranged at the bottom of the spray tower 200, and the air duct 300 is connected to the top of the spray tower 200, so that the organic waste gas can pass through the entire spray tower 200 from bottom to top, thereby increasing the dust removal and cooling effects. The same is true for the air duct 300 connected to the top of the cooler 400. The organic waste gas entering the cooler 400 will pass through the heat exchange tube bundle 500 from top to bottom, and the condensed oil formed by the condensation of the organic waste gas will be discharged from the bottom of the cooler 400. This arrangement can increase the contact time between the organic waste gas and the heat exchange tube bundle 500, thereby improving the condensation effect and improving the purification effect. In addition, the inlet and outlet of the organic waste gas in the cooler 400 adopts a top-in and bottom-out structural design, which can also prevent the condensed oil from being heated again.

[0048] Preferably, a packing layer 220 and a first spray component 230 are provided inside the spray tower 200. The first spray component 230 is arranged above the packing layer 220. The first spray component 230 is connected to the first spray water tank 250 through the first spray water pump 240. The first spray water tank 250 is connected to the bottom of the spray tower 200 for recovering spray water.

[0049] Specifically, see Figure 1 A packing layer 220 is horizontally arranged inside the spray tower 200, and a first spray component 230 is mounted above the packing layer 220. The first spray component 230 can adjust the number of spray heads according to actual conditions. The organic waste gas entering the spray tower 200 will be cooled and dust-removed, and the packing layer 220 mainly functions to reduce the temperature of the spray water. After being sprayed out, the spray water first passes through the packing layer 220 and then acts on the organic waste gas.

[0050] In this embodiment, the power for spraying water in the first spray component 230 comes from the first spray water pump 240. The first spray water pump 240 is connected to the first spray water tank 250. The first spray water pump 240 can spray the water in the first spray water tank 250 through the first spray component 230. In order to save water resources, the first spray water tank 250 is connected to the bottom of the spray tower 200, so that the spray water can be recycled, saving the cost of treating organic waste gas.

[0051] Preferably, two packing layers 220 and two first spray components 230 matching therewith are provided inside the spray tower 200 , and both first spray components 230 are connected to the first spray water tank 250 through the first spray water pump 240 .

[0052] It can be understood that in this embodiment, two groups of packing layers 220 and a first spray component 230 are arranged in the vertical direction inside the spray tower 200. This arrangement can re-treat the organic waste gas that has been treated once, thereby increasing the dust removal and cooling effects of the spray tower 200; it should be noted that the two first spray components 230 are connected to the same first spray water pump 240 and the first spray water tank 250.

[0053] Of course, the number of groups of the packing layer 220 and the first spray component 230 matched therewith provided inside the spray tower 200 can be adjusted according to actual conditions, as long as the expected effect is achieved.

[0054] Preferably, the cooler 400 is a detachably installable steel frame structure, and the heat exchange tube bundle 500 is installed near the top of the cooler 400 .

[0055] Specifically, Figure 2 As shown, the cooler 400 adopts a steel frame structure, which is installed in a building block style and stacked up and down. The frames are connected by bolts. This arrangement is convenient for installation and maintenance. The heat exchange tube bundle 500 is installed near the top of the cooler 400 in order to better cool the organic waste gas entering the cooler 400.

[0056] Preferably, the bottom of the cooler 400 is a funnel-shaped structure, and an exhaust pipe 410 and an oil drain valve 420 are also provided at the bottom of the cooler 400. The exhaust pipe 410 is used to discharge the purified gas from the organic waste gas, and the oil drain valve 420 is arranged at the outlet position of the bottom of the cooler 400 to control the outflow of condensed oil. An oil drain component 430 for collecting condensed oil is provided at the corresponding position of the oil drain valve 420.

[0057] In this embodiment, if Figure 2As shown, the bottom of the cooler 400 is a funnel-shaped structure, which is convenient for the condensed oil to gather downward and be collected. An exhaust pipe 410 is provided at the position of the funnel-shaped structure at the bottom of the cooler 400, so that the purified exhaust gas can be discharged from the exhaust pipe 410. An oil drain valve 420 is also provided at the position of the funnel-shaped outlet. When the oil drain valve 420 is closed, the condensed oil will not be able to flow out. An oil drain component 430 is provided directly below the oil drain valve 420 for collecting the condensed oil.

[0058] Preferably, a wind shielding structure 440 is further provided at the outlet at the bottom of the cooler 400 .

[0059] It can be understood that a wind shield structure 440 is also provided at the outlet of the funnel-shaped structure at the bottom of the cooler 400 , so that condensed oil can be prevented from being brought into the exhaust pipe 410 .

[0060] Preferably, the heat exchange tube bundle 500 is connected to the dry cooling section radiator 610 and the wet cooling section radiator 620 inside the cooling tower 600 in sequence. A circulating water pump 510 is provided at a position of the heat exchange tube bundle 500 near the cooling tower 600, which is used to provide circulation power for the water inside the heat exchange tube bundle 500. A second spray component 630 is provided above the wet cooling section radiator 620. The second spray component 630 is connected to the second spray water tank 650 through a second spray water pump 640. A fan unit 660 is provided on the top of the cooling tower 600. The dry cooling section louver 670 is arranged near the dry cooling section radiator 610, and the wet cooling section louver 680 is arranged near the wet cooling section radiator 620.

[0061] Specifically, Figure 3 As shown, the liquid used to cool the organic waste gas inside the heat exchange tube bundle 500 is cooling water. The heat exchange tube bundle 500 is installed in the cooler 400 and is connected to the dry cooling section radiator 610 and the wet cooling section radiator 620 inside the cooling tower 600, finally forming a loop. In order to enable the cooling water inside to circulate, a circulating water pump 510 is installed on the heat exchange tube bundle 500 to provide power for the circulation of the cooling water.

[0062] It can be understood that the cooling water will exchange heat with the organic waste gas in the cooler 400, absorb the heat of the organic waste gas, and the cooling water after absorbing the heat will enter the cooling tower 600 for re-cooling; therefore, the cooling tower 600 is also provided with a second spray component 630, a dry cooling section louver 670, a wet cooling section louver 680 and a fan unit 660; the dry cooling section louver 670 and the wet cooling section louver 680 can respectively dissipate heat for the cold section radiator and the wet cooling section radiator 620, the second spray component 630 can spray water onto the wet cooling section radiator 620 for further heat dissipation, and the fan unit 660 can also be turned on or off according to actual conditions; wherein the second spray component 630 is connected to the second spray water tank 650 through the second spray water pump 640.

[0063] The specific implementation process is as follows: when the ambient temperature is lower than the dry working condition design temperature, the cooling water is cooled by the dry cooling section radiator 610 to the water temperature of the process section in the cooler 400, and the fan group 660 is operated at a reduced frequency; at this time, the second spray component 630 is closed and no spray water is needed; when the ambient temperature reaches the dry working condition design temperature, the fan is operated at 100% and the dry cooling section reaches the maximum capacity value; when the ambient temperature rises further, the opening of the dry cooling section shutter 670 is gradually reduced, and the ventilation volume of the wet cooling section is increased, that is, the opening of the wet cooling section shutter 680 is increased, and the second spray component 630 is opened at the same time to meet the water temperature requirement of the process section in the cooler 400; when the ambient temperature reaches the summer design condition, the dry cooling section shutter 670 is completely closed, and only the wet cooling section is operated to reach the maximum cooling capacity of the cooling tower 600.

[0064] With this arrangement, the cooling tower 600 operates dry in winter, and the frequency of the fan unit 660 is adjusted to match the cooling water temperature, which can reduce the power consumption of the fan. In summer, the cooling tower 600 operates in a dry and wet combination, and water saving can be achieved by adjusting the window opening of the dry and cold section louvers 670 to match the dry and wet section air volume and minimize the water consumption in the evaporation section.

[0065] Preferably, two dry cooling section radiators 610 and two wet cooling section radiators 620 are provided, and the second spray component 630 is provided between the two wet cooling section radiators 620 .

[0066] It can be understood that in order to improve the cooling capacity of the cooling tower 600, two dry cooling section radiators 610 and wet cooling section radiators 620 are symmetrically arranged inside the cooling tower 600. Similarly, two dry cooling section louvers 670 and wet cooling section louvers 680 are also arranged. The heat exchange tube bundles 500 of the two groups of dry cooling section radiators 610 and wet cooling section radiators 620 are connected in parallel. It should be noted that only one second spray component 630 is arranged. Therefore, the second spray component 630 is arranged between the two wet cooling section radiators 620, so that the second spray component 630 can spray water and act on the wet cooling section radiator 620 to dissipate heat at the same time.

[0067] Preferably, the heat exchange tube bundle 500 is connected to an exhaust passage 520 near the dry cooling section louver 670 .

[0068] It can be understood that the heat exchange tube bundle 500 is connected to an exhaust channel 520 for exhausting the gas generated during the heat exchange process in the heat exchange tube bundle 500. In order to enable the gas to be discharged quickly, the exhaust channel 520 is set at the position of the dry cooling section louver 670.

[0069] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0070] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0071] The above is a detailed introduction to the embodiments provided by the utility model. This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
