Description

Technical Field

[0001] The utility model relates to the technical field of air purification equipment, in particular to a cryogenic air-conditioning unit for tail gas purification. Background Art

[0002] Purification air conditioners are mainly used to purify exhaust gases from production and life in confined spaces, and can also regulate indoor temperature. Especially in large confined spaces such as operating rooms and laboratories, purification air conditioners draw indoor air into the unit, and after being processed by the unit such as freezing and dehumidification and then heating and heating, the air is discharged or mixed with new air to replenish the chamber. For example, the invention patent No. CN202410257209 discloses a horizontal dual-cold source dehumidification air conditioner, which specifically discloses a heating, cooling and dehumidification integrated unit. When the equipment is used, a large amount of condensed water is generated around the evaporator, and the microorganisms and other pollution sources in the mixed air condense and flow to the bottom of the unit. Traditional technologies often use drain valves or timed suction to discharge the water at the bottom of the unit at a regular interval. However, due to the lack of fluidity of the cavity wall of the container for holding condensed water at the bottom of the unit, the side walls of the bottom of the unit cannot be flushed when discharging water, which easily leads to pollution such as microbial accumulation and corruption, affecting the purification effect of the air conditioning unit. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the residual condensed water in the air-conditioning unit may cause gas pollution and affect the purification effect of the air-conditioning unit.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a deep-cold air-conditioning unit for exhaust gas purification, comprising a fresh air module, a purification module, an air temperature processing module and an air supply pipe arranged in sequence according to the air flow direction, the fresh air module comprises an air intake fan, the air intake fan draws external air into the unit, the air temperature processing module comprises a primary air treatment device installed on one side of the purification module with the air intake fan, a secondary air treatment device arranged on one side of the primary air treatment device, and a drainage device arranged below the primary air treatment device and the secondary air treatment device, the secondary air treatment device comprises an evaporator, a condenser, and a compressor connected between the evaporator and the condenser, the drainage device comprises a water accumulation pan installed below the primary air treatment device and the evaporator, a guide plate movably installed below the water accumulation pan, a switch plate movably installed on the guide plate, and a resist column arranged below the guide plate, after the guide plate is rotated into place, the resist column can push the switch plate to open the gap between the switch plate and the guide plate.

[0005] Furthermore, a waste liquid discharge port is provided on the bottom of the water accumulation tray, and the guide plate covers the waste liquid discharge port.

[0006] Furthermore, the switch plate is arranged away from the connection between the guide plate and the water collection tray, one side of the switch plate is hinged to the guide plate, and the other side of the switch plate is pressed against the side wall of the guide plate.

[0007] Furthermore, there are multiple support pillars, and the multiple support pillars are arranged in parallel.

[0008] Furthermore, a linkage plate is fixedly mounted on the bottom of the support column, and a plurality of the support columns are fixed in parallel on the linkage plate.

[0009] Furthermore, a control pin is installed on the outer side wall of the guide plate.

[0010] Furthermore, a hook is movably installed on the side wall of the water collection tray, and the hook can be clamped onto the control pin.

[0011] Furthermore, a supporting plate is fixedly mounted on the linkage plate, and the control pin can be mounted on the supporting plate.

[0012] The beneficial effect of the present invention is that when the first-level air treatment equipment condenses and purifies the fresh air, the impurities in the fresh air are absorbed by the condensed water and accumulated in the water accumulation tray. When the condensed water in the water accumulation tray reaches the discharge standard, the guide plate is rotated. When the guide plate is rotated into place, the gap between the switch plate and the guide plate is opened, and the condensed water can flow out from the gap. Since the guide plate is in an inclined state after flipping, the water flow can flush the surface of the guide plate when it is discharged. At the same time, the operator can also flush the surface of the guide plate where the condensed water is collected, thereby avoiding the accumulation and corruption of microorganisms on the guide plate and improving the purification effect.

DETAILED DESCRIPTION

[0021] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0022] like Figures 1 to 6 As shown, this embodiment provides a cryogenic air conditioning unit for exhaust gas purification, including a fresh air module 10, a purification module 20, an air temperature processing module 30, and an air supply pipe 40. The fresh air module 10, the purification module 20, the air temperature processing module 30, and the air supply pipe 40 are arranged in sequence according to the air flow direction. That is, the air passes through the fresh air module 10, and is processed in sequence by each module such as cooling and dehumidification to form qualified fresh air. The fresh air is discharged from the air supply pipe 40 to a designated space.

[0023] like Figure 1 As shown, the fresh air module 10 includes a fresh air duct 110, a filter membrane 120 installed at the outlet of the fresh air duct 110, and an air inlet fan 130 arranged on one side of the filter membrane 120. The fresh air duct 110 and the air inlet fan 130 are respectively arranged on both sides of the filter membrane 120. Air outside the unit is sucked into the unit through the fresh air duct 110 by the air inlet fan 130. The fresh air is filtered by the filter membrane 120, which absorbs and filters impurities such as dust in the fresh air, achieving preliminary filtration and purification of the fresh air.

[0024] like Figure 1As shown, the purification module 20 includes a first bag filter 210 provided on one side of the air inlet fan 130 and a second bag filter 220 provided on one side of the first bag filter 210. The first bag filter 210 is provided in the air inlet direction of the air inlet fan 130. The filtering area of ​​the first bag filter 210 is larger than the filtering area of ​​the second bag filter 210. The first bag filter 210 can perform a primary filtration on the fresh air and perform a primary filtration on the impurities remaining in the fresh air. The second bag filter 220 is provided in the air outlet direction of the first bag filter 210. The filtering aperture of the second bag filter 220 is finer and can perform a secondary filtration on the fresh air. In conjunction with the filter membrane 120 and the first bag filter 220, three-stage filtration is achieved until the fineness of impurities such as microorganisms or dust in the air reaches the air standard of the chamber.

[0025] like Figure 1 As shown, the air temperature processing module 30 includes a primary air treatment device 310 arranged on one side of the purification module 20, a secondary air treatment device arranged on one side of the primary air treatment device 310, and a drainage device 350 arranged below the primary air treatment device 310 and the secondary air treatment device.

[0026] In this embodiment, an evaporator is preferably used as the first-level air treatment equipment 310, wherein the refrigerant flowing in the evaporator is a refrigerant liquid. The first-level air treatment equipment 310 uses an external air compressor and a pressure expansion valve to input the refrigerant. When the refrigerant in the evaporator vaporizes and absorbs heat, the surrounding temperature drops. When the fresh air that has undergone three-stage purification passes through the first-level air treatment equipment 310, the temperature drops significantly, and the moisture in the fresh air condenses and flows into the drainage device 350. The secondary air treatment equipment includes an evaporator 320, a condenser 330, and a compressor 340 connected between the evaporator 320 and the condenser 330. One end of the evaporator 320 is connected to the condenser 330 through the compressor 340, and the other end of the evaporator 320 is directly connected to the condenser 330 through a vortex tube. The refrigerant in the evaporator 320 is compressed by the compressor and input into the condenser 330. When the refrigerant in the condenser 330 is liquefied and releases heat, the surrounding temperature rises. The liquefied refrigerant flows back to the evaporator 310 through the vortex tube. Since the air pressure in the evaporator 320 is reduced under the suction of the compressor 340, the refrigerant is vaporized and absorbs heat in the evaporator 310. When the fresh air flows through the air temperature processing module 30, after the cold and hot adjustment process of the evaporator 310 and the condenser 330, the temperature of the fresh air is adjusted to the required level of the chamber.

[0027] The temperature of the primary air handling device 310 and the evaporator 320 is relatively low, and a large amount of condensed water is generated when fresh air flows through, and the condensed water flows into the drainage device 350. Figures 2 to 6As shown, the drainage device 350 includes a water collection tray 351 arranged below the primary air handling equipment 310 and the evaporator 320, a guide plate 352 movably installed below the water collection tray 351, a switch plate 353 movably installed on the guide plate 352, and a support column 354 arranged below the guide plate 352.

[0028] The water collection pan 351 is provided in correspondence with the temperature control module 30 and can house the primary air handling device 310 and the evaporator 320. A waste liquid discharge port 355 is defined at the bottom of the water collection pan 351. A guide plate 352 is hingedly connected to the water collection pan 351, covering the waste liquid discharge port 355. Evaporator condensate collected in the water collection pan 351 can flow to the guide plate 352 through the waste liquid discharge port 355. A switch plate 353 is provided away from the connection between the guide plate 352 and the water collection pan 351. The switch plate 353 is disposed within the water collection pan 351. One side of the switch plate 353 is hingedly connected to the guide plate 352, while the other side of the switch plate 353 abuts against the side wall of the guide plate 352. The support column 354 is set corresponding to the switch plate 353. There are multiple support columns 354. A linkage plate 356 is fixedly installed at the bottom of the support column 354. Multiple support columns 354 are fixed in parallel on the linkage plate 356. Under the push of the support column 354, the switch plate 353 can be rotated relative to the guide plate 352, so that a gap appears between the switch plate 353 and the side wall of the guide plate 352, and the water collected in the guide plate 352 flows out from the gap.

[0029] Preferably, a hook 357 is movably installed on the side wall of the water collection tray 351, and a control pin 358 is installed on the outer wall of the guide plate 352. By rotating the hook 357 on the water collection tray 351, the hook 357 can be clamped onto the control pin 358. Under the clamping fit of the hook 357 and the control pin 358, the guide plate 352 can maintain the sealing state of the waste liquid discharge port 335.

[0030] Preferably, a support plate 359 is fixedly installed on the linkage plate 356, and the support plate 359 and the control pin 358 are correspondingly arranged. After the guide plate 352 rotates, the control pin 358 can be placed on the support plate 359. When the control pin 358 is placed on the support plate 359, the support column 354 pushes the switch plate 353 to open the water leakage gap.

[0031] When the above-mentioned cryogenic air conditioning unit for exhaust gas purification is in use, fresh air is sucked in by the air inlet fan 130 in the fresh air module 10, passes through the fresh air pipeline 110, and enters the unit. The fresh air then passes through the filter membrane 120, the first bag filter 210, and the second bag filter 220 in the purification module 20, completing a three-stage filtration of microorganisms and dust impurities in the fresh air to ensure that the fresh air meets the impurity standards. When the filtered and purified fresh air is near the primary air treatment equipment 310 and evaporator 320 in the air temperature processing module 30, the moisture in the air condenses and accumulates in the water accumulation tray 351. After passing through the condenser 330, the low-temperature fresh air is adjusted to a specified temperature and discharged into the chamber through the air supply pipe 40. When the condensate in the water accumulation pan 351 reaches a specified height, the guide plate 352 is rotated by controlling the pin 358 until the pin 358 rests on the support plate 359. Once the guide plate 352 is flipped into place, the support column 354 pushes against the switch plate 353, opening the gap between the switch plate 353 and the guide plate 352 and allowing the condensate to flow out. Since the water accumulation pan 351 is tilted and extends below the unit, workers can clean the flip cover 352 by flushing it, preventing microbial scaling and corruption and reducing air pollution in the unit. Once the flip cover 352 is cleaned, it is rotated in the opposite direction again. Under the influence of its own weight, the switch plate 353, freed from the support column 354, rotates synchronously until the leaking gap between the guide plate 352 and the switch plate 353 is sealed.

[0032] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
