Description

Technical Field

[0001] The present invention relates to the field of civil engineering technology, and in particular to an assembled negative pressure channel and an installation method that can be used for the conversion of temporary isolation points in public rental housing from normal to epidemic conditions. Background Art

[0002] When an epidemic breaks out in a certain place, a large number of temporary infectious disease isolation wards are needed. The existing general hospital resources are insufficient, and isolation hospitals need to be built to fight the epidemic. When the epidemic is over, the built isolation hospitals will be suspended and the facilities will be retained for future use. When not in use, it will cause a waste of money and space.

[0003] Most cities have public rental housing built with the support of national policies. They are affordable housing and serve a large number of people with high mobility. There are often a large number of vacant public rental housing waiting to be used. If the vacant public rental housing is used as a temporary isolation ward, it will not only save a lot of money, but also enable rapid entry into the state of epidemic preparedness. For the above reasons, it is necessary to provide a prefabricated negative pressure channel that can be used for the temporary isolation point in the public rental housing to achieve the conversion between normal use and epidemic use. Summary of the invention

[0004] The purpose of the present invention is to provide an assembled negative pressure channel and installation method that can be used for the conversion of temporary isolation points in public rental housing from normal to epidemic conditions, so as to achieve the purpose mentioned in the background technology of using spare public rental housing as temporary isolation wards, which not only saves a lot of money, but also can quickly enter the isolation and anti-epidemic state, and realize the conversion between normal use and use during the epidemic period.

[0005] To achieve the above-mentioned purpose, the first technical solution provided by the present invention is an assembled negative pressure channel that can be used for the conversion of temporary isolation points in public rental housing from normal to epidemic, including a negative pressure channel, and an installation mechanism connecting the negative pressure channel and the door of the public rental housing unit;

[0006] The negative pressure channel includes the disinfection area and the negative pressure area;

[0007] The negative pressure area is provided with a fresh air inlet, a negative pressure exhaust mechanism, and a gas processing mechanism connected to the negative pressure exhaust mechanism;

[0008] The gas treatment mechanism includes a treatment cylinder, a waste gas inlet is provided at the lower part of the treatment cylinder, the waste gas inlet is connected to the negative pressure exhaust mechanism, a purified gas outlet is provided at the top of the treatment cylinder, a disinfectant is filled in the treatment cylinder, and a disinfection auxiliary device is also provided in the treatment cylinder.

[0009] The installation mechanism connects the negative pressure channel with the unit door of the public rental housing, so that the public rental housing can be quickly converted into a temporary isolation point, enter the epidemic preparedness state, and make full use of the vacant public rental housing. When the epidemic is over, the negative pressure channel will be dismantled and quickly converted into ordinary public rental housing to meet the city's demand for affordable housing. Not only does it save a lot of money, but it can also quickly enter the isolation and anti-epidemic state, and realize the purpose of conversion between normal use and epidemic period use. The negative pressure channel is divided into a disinfection area and a negative pressure area. After disinfection, it enters the negative pressure area. The exhaust gas in the negative pressure area is treated by a gas treatment mechanism to avoid cross infection.

[0010] Preferably, the disinfection auxiliary device comprises a fixed filter screen, a rotating blade and a driving device, wherein the rotating blade is arranged below the fixed filter screen, and the driving device provides a rotating power for the rotating blade;

[0011] There are multiple filter holes evenly arranged on the fixed filter screen, which are conical vent holes. The fixed filter screen fits tightly with the rotating blades.

[0012] The first-level disinfection is below the disinfection auxiliary device, and the second-level disinfection is above the disinfection auxiliary device.

[0013] The waste gas enters the treatment cylinder and is fully in contact with the disinfectant to achieve primary disinfection. Under the action of the disinfection auxiliary device, secondary disinfection is achieved. The disinfection auxiliary device has a simple structure. The waste gas bubbles rise to the fixed filter screen. Under the rotating cutting action of the rotating blades, the bubbles are cut and become smaller, so that the waste gas can fully contact the disinfectant, so that the gas can be purified and then discharged after purification.

[0014] Preferably, the driving device is arranged above the processing cylinder, and the driving device is provided with an output shaft, and the output shaft passes through the fixed filter screen and is connected with the rotating blade.

[0015] The fixed filter screen is connected to the processing cylinder, and the fixed filter screen is connected to the output shaft through a bearing.

[0016] The positions of the fixed filter screen and the treatment cylinder are relatively fixed, and the output shaft and the fixed filter screen are connected through a bearing, so that when the driving device drives the rotating blade to rotate, the fixed filter screen remains fixed relative to the treatment cylinder.

[0017] Preferably, the fixed filter screen is a conical structure, and the blade motion trajectory of the rotating blade is conical.

[0018] The setting of the conical structure makes the bubbles gather in the central position as much as possible, and the cutting efficiency of the rotating blades in the central position is high and the bubble granulation speed is fast.

[0019] Preferably, the fresh air inlet is arranged at the top of the negative pressure area, and a fan is provided at the fresh air inlet. The fan is provided with a central axis, and the central axis of the fan is the output axis.

[0020] Under the action of negative pressure, fresh air continuously enters the negative pressure channel. A fan is installed at the fresh air inlet. The central axis of the fan is the output axis, that is, the fan replaces the driving device. The rotation of the fan drives the rotation of the rotating blades. This saves energy and improves efficiency.

[0021] Preferably, a pressure reducing releaser is also provided at the waste gas inlet () in the treatment cylinder (), and a plurality of pressure reducing plates are provided in the pressure reducing releaser, and release holes are provided on the pressure reducing plates. The pressure reducing plates are provided with a first-stage pressure reducing plate, a second-stage pressure reducing plate to an N-stage pressure reducing plate from bottom to top, and the release amount of the release hole increases with the increase in the number of pressure reducing plates.

[0022] In order to increase the granulation efficiency of waste gas, a pressure reducing releaser is set at the waste gas inlet, and multi-stage pressure reduction reduces the gas pressure while granulating the gas, thereby increasing the efficiency of the first-level disinfection, reducing the granulation pressure of the disinfection auxiliary device, and improving the efficiency of the second-level disinfection.

[0023] Preferably, the installation mechanism includes a hanging plate provided on the top of the outer side of the public rental housing unit door, a first installation position provided on the outer bottom thereof, a gusset plate provided on the top of the outer side of the negative pressure zone, the hanging plate and the gusset plate are installed by two inverted L-shaped plates interlocked with each other, a door platform is provided inside the negative pressure zone, a second installation position is provided on the door platform, the first installation position is movably connected to the second installation position, and sealing strips are provided on both sides of the negative pressure zone;

[0024] A hydraulic wheel is arranged at the bottom of the negative pressure channel.

[0025] When installing the negative pressure channel, you need to raise the hydraulic wheel first and adjust the position of the negative pressure channel. It should be located above the public rental housing unit door and higher than the actual installation position. Adjust the hydraulic wheel and slowly lower the negative pressure channel so that the buckle plate is buckled on the hanging plate. Fix the hydraulic wheel and then connect the first installation position with the second installation position. Since the buckle plate is buckled with the hanging plate and the bottom is supported by the hydraulic wheel, the connection between the first installation position and the second installation position only needs to be fixed in position. The connection method can be pre-embedded screw holes at the lower part of the outer side of the public rental housing unit door, connected by screws, or clamped, or pre-embedded hanging rings on the outer side of the door and the outer side of the negative pressure channel, and the hanging rings can be connected and fixed.

[0026] Preferably, the top of the negative pressure channel is set as the top of the photovoltaic channel.

[0027] Solar power generation products are integrated on the top of the negative pressure channel to realize the integration of the photovoltaic channel, provide the required electricity for the negative pressure channel, and use green energy to reduce energy consumption.

[0028] Preferably, the purified gas outlet is connected to a tee, the tee is connected to the exhaust port and the return pipe, a gas detection device and an airflow controller are provided between the purified gas outlet and the tee, and the return pipe is connected to the exhaust gas inlet.

[0029] In order to avoid the exhaust gas being discharged without being completely purified due to insufficient exhaust gas disinfection, a gas detection device and an airflow controller are installed at the outlet of the purified gas. When it is detected that the gas is not completely purified, the airflow controller adjusts the airflow direction so that the incompletely purified gas flows to the reflux pipe and enters the exhaust gas inlet again to achieve secondary purification. When the gas detection device detects that the gas has been completely purified, the airflow controller adjusts the airflow direction so that the gas flows to the exhaust port and is discharged to the outside.

[0030] The second technical solution provided by the present invention is an installation method of an assembled negative pressure channel that can be used for the conversion of temporary isolation points from normal to epidemic situations in public rental housing, comprising the following steps:

[0031] Steps: Assemble the negative pressure channel;

[0032] Steps: After the negative pressure channel is assembled, the hydraulic wheel rises and moves the negative pressure channel so that the gusset plate moves above the hanging plate;

[0033] Steps: Lower the hydraulic wheel, and when the gusset plate is fully in contact with the hanging plate, fix the hydraulic wheel;

[0034] Step: Install the first installation position and the second installation position together;

[0035] Steps: Seal the negative pressure channel and the public rental housing installation point with sealing strips.

[0036] The negative pressure channel is easy to install and operate.

[0037] Beneficial effects of the present invention:

[0038] The negative pressure channel is connected to the public rental housing through the installation mechanism, so that the public rental housing can be quickly converted into a temporary isolation point, enter the epidemic preparation state, and make full use of the vacant public rental housing. When the epidemic is over, the negative pressure channel is dismantled and quickly converted into ordinary public rental housing to meet the city's demand for affordable housing, which not only saves a lot of money, but also can quickly enter the isolation and anti-epidemic state, and realize the conversion between normal use and epidemic use; through the disinfection auxiliary device and the pressure relief device, the exhaust gas of the negative pressure channel is completely purified. The negative pressure channel is easy to install and easy to operate.

DETAILED DESCRIPTION

[0045] The present invention is further described below in conjunction with the embodiments, but those skilled in the art will understand that the following examples are only used to illustrate the present invention and should not be considered to limit the scope of the present invention. If no specific conditions are specified in the examples, they are carried out under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used without indicating the manufacturer are all conventional products that can be purchased commercially; the specific embodiments described are only used to explain the principles of the present invention and are not used to limit the present invention.

[0046] In view of the existing technology, in order to realize the conversion of vacant public rental housing for normal use and use during the epidemic period, a large number of people who need to be isolated can quickly enter the isolation and anti-epidemic state. The first technical solution provided by the present invention is as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 The illustrated embodiment is a prefabricated negative pressure channel that can be used for the temporary isolation point in public rental housing to convert from normal to epidemic situation. It includes a negative pressure channel 1, and a mounting mechanism 2 connecting the negative pressure channel 1 and the unit door of the public rental housing;

[0047] The negative pressure channel 1 includes a disinfection zone 3 and a negative pressure zone 4;

[0048] The negative pressure area 4 is provided with a fresh air inlet 5, a negative pressure exhaust mechanism 6, and a gas processing mechanism 7 connected to the negative pressure exhaust mechanism 6;

[0049] The installation mechanism 2 connects the negative pressure channel 1 to the unit door of the public rental housing, so that the public rental housing can be quickly converted into a temporary isolation point, enter the epidemic preparedness state, and make full use of the vacant public rental housing. When the epidemic is over, the negative pressure channel 1 is dismantled and quickly converted into ordinary public rental housing to meet the city's demand for affordable housing. Not only does it save a lot of money, but it can also quickly enter the isolation and anti-epidemic state, and achieve the purpose of conversion from normal use to use during the epidemic period. The negative pressure channel 1 is divided into a disinfection area 3 and a negative pressure area 4. After disinfection, it enters the negative pressure area 4. In order to avoid cross infection, the negative pressure exhaust mechanism 6 will pass the air through the negative pressure channel 1 to the gas treatment mechanism 7 for processing, and then discharge the purified and qualified air. The negative pressure exhaust mechanism 6 can be an ordinary vacuum pump or blower on the market.

[0050] The negative pressure channel 1 includes a disinfection zone 3 and a negative pressure zone 4. The disinfection zone 3 is provided with a plurality of disinfection nozzles, and its structural composition can be assembled according to existing disinfection pipelines and facilities. When the quarantined persons enter, they first enter the disinfection zone 3, and the disinfection nozzles disinfect the quarantined persons. The disinfection zone realizes the basic disinfection function. The disinfection zone 3 and the negative pressure zone 4 are clearly distinguished by a partition, and a door is arranged on the partition to ensure the negative pressure environment of the negative pressure zone 4.

[0051] The installation mechanism 2 includes a hanging plate 201 provided on the top of the outer side of the public rental housing unit door, a first installation position 202 provided on the bottom of the outer side, a gusset plate 203 provided on the top of the outer side of the negative pressure zone 4, the hanging plate 201 and the gusset plate 203 are installed by two inverted L-shaped plates that are mutually buckled, a door platform 204 is provided inside the negative pressure zone 4, the door platform 204 is provided with a second installation position 205, the first installation position 202 is movably connected to the second installation position 205, and sealing strips 206 are provided on both sides of the negative pressure zone 4;

[0052] A hydraulic wheel 14 is provided at the bottom of the negative pressure channel 1 .

[0053] When installing the negative pressure channel 1, it is necessary to first raise the hydraulic wheel 14 and adjust the position of the negative pressure channel 1, which should be located above the public rental housing unit door and higher than the actual installation position. After adjusting the hydraulic wheel 14, the negative pressure channel 1 slowly descends so that the buckle plate 203 is buckled on the hanging plate 201. After the buckle is stable, fix the hydraulic wheel 14, and then connect the first installation position 202 with the second installation position 205. Since the buckle plate 203 is buckled with the hanging plate 201 and the bottom is supported by the hydraulic wheel 14, the connection between the first installation position 202 and the second installation position 205 only needs to be fixed in position. The connection method can be pre-embedded screw holes at the lower part of the outer side of the public rental housing unit door, connected by screws, or clamped, or pre-set hanging rings on the outer side of the door and the outer side of the negative pressure channel 1, and the hanging rings can be connected and fixed.

[0054] This connection method has a simple structure and is easy to assemble and disassemble. There are four or six hydraulic wheels 14, all of which are hydraulic wheels 14 with brakes. Ordinary hydraulic wheels with brakes on the market can be selected. It is preferred to connect several hydraulic wheels 14 in series to adjust the lifting and lowering of the negative pressure channel 1 as a whole.

[0055] The hanging plate 201 should be thicker to avoid excessive force on the hanging plate 201 when the hydraulic wheel 14 drops too much. In order to achieve full contact while avoiding excessive force, a pressure sensor can be set at the hanging plate 201 or the buckle plate 203. The pressure sensor can be an ordinary pressure sensor on the market with a suitable force range.

[0056] The sealing pad strip 206 can be sealed with foam or with adhesive tape, etc. The sealing pad strip 206 can also be used to seal the hanging plate 201 and the first installation position 202.

[0057] The top of the negative pressure channel 1 is set as the photovoltaic channel top 15.

[0058] The solar power generation product is integrated on the top of the negative pressure channel 1 to realize the integration of the photovoltaic channel, provide the required electrical energy for the negative pressure channel 1, and can provide energy to the negative pressure exhaust mechanism 6. When the driving device 1203 is an ordinary motor, it can also provide energy to the driving device 1203. At night or on rainy days, a battery is used to provide the required electrical energy to the negative pressure channel 1. The mutual conversion technology between solar panel power generation and battery power supply is already quite mature, and existing technology can be used.

[0059] The gas treatment mechanism 7 includes a treatment tube 8, a waste gas inlet 9 is provided at the lower part of the treatment tube 8, the waste gas inlet 9 is connected to the negative pressure exhaust mechanism 6, a purified gas outlet 10 is provided at the top of the treatment tube 8, a disinfectant 11 is filled in the treatment tube 8, and a disinfection auxiliary device 12 is also provided in the treatment tube 8.

[0060] After the waste gas enters the disinfectant 11, it is difficult to fully disinfect it only by passing through the disinfectant 11 because the bubbles are too large. Therefore, the disinfection auxiliary device 12 is required to granulate the waste gas. The granulated small bubbles can fully contact with the disinfectant to achieve a complete purification effect.

[0061] The disinfection auxiliary device 12 includes a fixed filter screen 1201, a rotating blade 1202 and a driving device 1203. The rotating blade 1202 is arranged below the fixed filter screen 1201. The driving device 1203 provides a rotating power for the rotating blade 1202.

[0062] A plurality of filter holes 1204 are evenly arranged on the fixed filter screen 1201, and the filter holes 1204 are conical vents. The fixed filter screen 1201 fits tightly with the rotating blades 1202;

[0063] The area below the disinfection auxiliary device 12 is the primary disinfection area, and the area above the disinfection auxiliary device 12 is the secondary disinfection area.

[0064] The waste gas enters the treatment cylinder 8 and contacts the disinfectant 11 to achieve primary disinfection. Under the action of the disinfection auxiliary device 12, the bubbles are granulated to achieve secondary disinfection. The disinfection auxiliary device 12 has a simple structure. The waste gas bubbles rise to the fixed filter 1201. Under the rotating cutting action of the rotating blades 1202, the bubbles are cut and granulated, so that the waste gas can fully contact the disinfectant 11, so that the gas can be purified and discharged after purification.

[0065] The driving device 1203 is disposed above the treatment cylinder 8, and the driving device 1203 is provided with an output shaft 1205, and the output shaft 1205 penetrates the fixed filter screen 1201 and is connected to the rotating blade 1202;

[0066] The fixed filter screen 1201 is connected to the processing cylinder 8, and the fixed filter screen 1201 is connected to the output shaft 1205 through a bearing.

[0067] The positions of the fixed filter 1201 and the treatment barrel 8 are relatively fixed, and can be either a fixed connection or a detachable movable connection. The detachable movable connection can be by movably snapping the fixed filter 1201 onto the treatment barrel 8, or by providing a slot on the fixed filter 1201 and a rail on the treatment barrel 8. When the fixed filter 1201 is moved to the desired position, it can be fixed using a snap buckle.

[0068] The driving device 1203 can be a common motor to drive the rotating blades 1202 to rotate. The output shaft 1204 is connected to the fixed filter screen 1201 through a bearing, so that when the driving device 1203 drives the rotating blades 1202 to rotate, the fixed filter screen 1201 remains fixed relative to the treatment cylinder 8.

[0069] When the waste gas enters the treatment cylinder 8, large bubbles will enter. As the bubbles rise, they gradually become larger. Under the action of negative pressure, the bubbles rise rapidly and it is difficult for them to fully contact the disinfectant 11. The effect of the first-level disinfection is not obvious. If the granulation of the waste gas is only completed by the disinfection auxiliary device 12, the granulated bubbles will be large or the gas will accumulate at the fixed filter 1201, which will make the gas granulation efficiency low and the effect of the second-level disinfection will still be limited.

[0070] In order to improve the bubble granulation efficiency, the fixed filter 1201 is set to be conical, and the blade movement trajectory of the rotating blade 1202 is also conical, so that the bubbles are gathered in the central position as much as possible. The cutting efficiency of the rotating blade 1202 in the central position is high, the bubble granulation speed is fast, and the granulation efficiency is improved.

[0071] In order to increase the granulation efficiency of the waste gas, a decompression releaser 13 is further provided at the waste gas inlet (9) in the treatment cylinder (8), and a plurality of decompression plates 1301 are provided in the decompression releaser 13, and a release hole 1302 is provided on the decompression plate 1301. The decompression plates 1301 are provided with a first-stage decompression plate 1303, a second-stage decompression plate 1304 to an N-stage decompression plate from bottom to top, and the release amount of the release hole 1302 increases with the increase of the number of decompression plates 1301. Multi-stage decompression reduces the gas pressure and granulates the gas, thereby increasing the efficiency of the first-stage disinfection, reducing the granulation pressure of the disinfection auxiliary device 12, and also improving the efficiency of the second-stage disinfection.

[0072] The filter hole 1204 on the fixed filter screen 1201 is trapezoidal, with the lower opening larger than the upper opening, and the filter hole 1204 is smaller than the size of the bubbles released by the decompression releaser 13. Under the vibration of the negative pressure exhaust mechanism 6 and the cutting action of the rotating blade 1202, the bubble granulation efficiency is higher, making the secondary disinfection more complete.

[0073] The purified gas outlet 10 is connected to a tee, the tee is connected to an exhaust port 16 and a return pipe 17 , a gas detection device 18 and an airflow controller 19 are provided between the purified gas outlet 10 and the tee, and the return pipe 17 is connected to the exhaust gas inlet 9 .

[0074] In order to avoid the exhaust gas being discharged due to insufficient exhaust gas disinfection, a gas detection device 18 and an airflow controller 19 are installed at the purified gas outlet 10. When it is detected that the gas is not completely purified, the airflow controller 19 adjusts the airflow direction so that the incompletely purified gas flows to the reflux pipe 17 and enters the exhaust gas inlet 9 again to achieve secondary purification. When the gas detection device 18 detects that the gas has been completely purified, the airflow controller 19 adjusts the airflow direction so that the gas flows to the exhaust port 16 and is discharged to the outside.

[0075] The gas detection device 18 and the airflow controller 19 can be selected from common devices on the market. A one-way valve is provided at the place where the return pipe 17 leads to the exhaust gas inlet 9, and a one-way valve is also provided at the place where the exhaust gas inlet 9 leads to the gas treatment mechanism 7.

[0076] Under the action of negative pressure, fresh air continuously enters the negative pressure channel, and a fan 501 is installed at the fresh air inlet 5, which can provide kinetic energy for the rotating blades 1201. The fresh air inlet 5 is arranged at the top of the negative pressure area 4, and a fan 501 is arranged at the fresh air inlet 5, and the fan 501 is provided with a central axis, which is the output axis 1205.

[0077] Under the action of negative pressure, fresh air continuously enters the negative pressure channel, and a fan 501 is installed at the fresh air inlet 5. The central axis of the fan 501 is the output shaft 1204, that is, the fan 501 replaces the driving device 1203. The rotation of the fan 501 drives the rotation of the rotating blades 1202, thereby saving energy and improving efficiency.

[0078] An air filter is arranged outside the fresh air inlet 5, and the air filter may be a carbon mesh or a traditional air filter.

[0079] In order to ensure the negative pressure state of the negative pressure zone 4, the passage between the disinfection zone 3 and the negative pressure zone 4, and the passage between the negative pressure zone 4 and the public rental housing can be set as automatic doors, or doors with rolling shutters.

[0080] The second technical solution provided by the present invention is as follows Figure 1 , Figure 2 , Figure 3 The installation method of the assembled negative pressure channel that can be used for the temporary isolation point in public rental housing to convert from normal to epidemic situation as shown includes the following steps:

[0081] Step 1: Assemble the negative pressure channel 1;

[0082] Step 2: After the negative pressure channel 1 is assembled, the hydraulic wheel 14 is raised to move the negative pressure channel 1 so that the pinch plate 203 is moved above the hanging plate 201;

[0083] Step 3: lower the hydraulic wheel 14, and when the pinch plate 203 is fully in contact with the hanging plate 201, fix the hydraulic wheel 14;

[0084] Step 4: Install the first installation position 202 and the second installation position 205 in coordination;

[0085] Step 5: The negative pressure channel 1 and the public rental housing installation location are sealed with a sealing gasket strip 206.

[0086] The negative pressure channel 1 is easy to install and operate, and can be installed by one person.

[0087] The negative pressure channel 1 can be a pre-installed module, formed of cement or iron sheet, or a flexible material. To assemble the negative pressure channel 1, first assemble the overall structure of the negative pressure channel 1, then install the gusset plate 203, the door platform 204, the disinfection nozzle of the disinfection area 3 and the gas treatment mechanism 7. When assembling the gas treatment mechanism 7, it should be noted that the output shaft 1205 is connected to the fan 501 and the rotating blades 1202, and the output shaft 1205 is vertical.

[0088] Working process: In order to realize the conversion of public rental housing between normal use and use during the epidemic period, firstly, in the construction of public rental housing, in order to facilitate the conversion between normal use and epidemic period in the later stage, the hanging plate 201 and the first installation position 202 are preset, and the rain awning and outdoor steps used in normal use are installed on the preset hanging plate 201 and the first installation position 202. The negative pressure channel 1 is modularized, or the accessories of the negative pressure channel 1 are modularized, which is convenient and quick to assemble when assembly is required. Secondly, when it is necessary to assemble the negative pressure channel 1, the modularized gusset plate 203, door platform 204, disinfection spray device and gas treatment mechanism 7 are quickly installed to complete the assembly of the negative pressure channel 1, and the rain awning and outdoor steps used in normal use of the public rental housing are removed. Again, raise the hydraulic wheel 14, move the negative pressure channel 1 to face the public rental housing unit door, with the gusset plate 203 higher than the hanging plate 201, and adjust the left and right position of the negative pressure channel 1; then lower the hydraulic wheel 14, so that the gusset plate 203 fully contacts the hanging plate 201, fix the position and height of the hydraulic wheel 14, then install the first installation position 202 and the second installation position 205, and fill the sealing gasket strip 206. Once again, the negative pressure function of the negative pressure channel 1 is started, and the negative pressure exhaust mechanism 6 is energized. The negative pressure exhaust mechanism 6 exhausts air, and fresh air enters from the fresh air inlet 5. The waste gas is transported to the gas treatment mechanism 7 by the negative pressure exhaust mechanism 6. The waste gas first enters the pressure reducing releaser 13 through the waste gas inlet 9. After the step-by-step pressure reduction, the waste gas bubbles are reduced and the bubble pressure is reduced, that is, the rise is slow, and the first-level disinfection is completed by fully contacting with the disinfectant 11, and then it rises to the disinfection auxiliary device 12. Under the cutting action of the rotating blades 1202 and the vibration action of the negative pressure exhaust mechanism 6, the bubbles are granulated again and enter the second-level disinfection, so that the second-level disinfection is more sufficient; after the second-level disinfection is completed, the gas enters the purified gas outlet 10, is detected by the gas detection device 18, and then the airflow controller 19 determines whether to divert. When the gas detection device 18 detects that the purified gas is unqualified, the airflow controller 19 cuts off the channel of the exhaust port 16, opens the channel of the reflux pipe 17, and the gas enters the waste gas inlet 9 from the reflux pipe 17 for disinfection again. Finally, when it is necessary to convert the public rental housing into affordable housing for daily use, first cut off the power supply, detach the first installation position 202 from the second installation position 205, remove the sealing gasket 206, raise the hydraulic wheel 14, separate the buckle plate 203 from the hanging plate 201, and then move the negative pressure channel 1 to complete the disassembly of the negative pressure channel 1 and the public rental housing, and then install outdoor steps and awnings outside the public rental housing to convert the public rental housing for daily use; modularly disassemble and store the negative pressure channel 1.

[0089] In summary, in order to use the spare public rental housing as a temporary isolation ward, it not only saves a lot of money, but also can quickly enter the isolation and anti-epidemic state, and realize the purpose of conversion between normal use and epidemic period, the present invention provides an assembled negative pressure channel and installation method that can be used for the conversion of temporary isolation points in public rental housing from normal to epidemic. The negative pressure channel 1 is connected to the public rental housing through the installation mechanism 2, so that the public rental housing can be quickly converted into a temporary isolation point and enter the epidemic preparation state, making full use of the spare public rental housing. When the epidemic is over, the negative pressure channel 1 is dismantled and quickly converted into ordinary public rental housing to meet the city's demand for affordable housing. It not only saves a lot of money, but also can quickly enter the isolation and anti-epidemic state, and realize the purpose of conversion between normal use and epidemic period; the exhaust gas of the negative pressure channel 1 is completely purified through the disinfection auxiliary device 12 and the pressure reducing releaser 13.
