Abstract
The invention discloses a special space facility for constructing micro negative pressure, which can generate the micro negative pressure in the special space through relatively simple new construction or modification, thereby resisting the spread of viruses by means of air infection like a new coronavirus and having wide development prospect.
Description
Technical Field
The invention belongs to the field of specific infrastructure, and particularly relates to a specific space facility for constructing micro negative pressure.
Background
The existing negative pressure system has a complex and complicated structure, has single adaptability (is not wide enough), can achieve the negative pressure effect only by adopting special equipment, does not generally specify the air circulation direction, is not widely assisted by adopting special negative pressure equipment capable of preventing viruses from spreading in the human activity space, and therefore public facilities in the wide meaning of 'mail wheels', 'restaurants', 'gymnasiums' and the like cannot effectively block the viruses from spreading and have to be closed; on the other hand, most of the "nucleic acid detection" facilities of the "sentry box" widely adopted at the present stage are not "negative pressure facilities", and even if an air conditioner is installed, the "full-auxiliary armed" is required, namely, one protection facility for staff cannot be reduced.
Disclosure of Invention
In view of the above problems, the present invention provides such a scheme: a specific space facility for constructing micro negative pressure, which is structurally characterized in that: (1) changing the traditional air circulation mode of 'up-blowing and down-blowing' (because the physical principle of 'hot air rising' needs to be followed) and the opposite air circulation mode of 'up-blowing and down-blowing', wherein the changing method is realized by a 'suction pump system' positioned at the 'bottom end' or the 'middle end', so as to achieve 'micro negative pressure' of 'specific space'; (2) on the basis, the method is widely applied to public facilities in the wide sense of a mail wheel, a train (including a high-speed rail car), an aircraft cabin, a gymnasium, a restaurant, a classroom and the like from a negative pressure ambulance and a negative pressure ward in the prior art, and the key technology is that a new ventilation scheme of blowing up and sucking down is adopted; (3) the motive force for promoting the 'up-blowing and down-sucking' is 'down-sucking' (as long as the 'specific space' is in a 'micro negative pressure' state, fresh air naturally enters from the 'upper part' communicated with the outside), and the control scale adopts the method that the air flow exhaled by a human body does not reach the nostril part of the other party within the distance of 0.5 m as a standard; (4) considering that the motive force of the 'suck-down' is set according to the people stream, the automatic control part of the 'specific space' is a 'thermal infrared people stream tracking system' (i.e. where the people walk to 'suck-down' to track the start or close after the past) which is adopted in the larger 'specific space'; (5) considering that the "decibel" of the "noise" generated by the "downdraft" cannot be too large, a scheme of low-noise "suction pump" or a "power source" of the "suction pump" (a part emitting the "noise") is slightly far from the "working point" is adopted; (6) the "fresh air" discharged by the "up-blowing" should be ensured to be a "harmless gas" to the human body. Note: there are reports: the "tesla" car of the united states "masker" is capable of keeping the air inhaled by the person in the car free of "smoke" while traversing the fire area (no risk of traversing, while other cars do not), this "prior art" being "paid" or "gratuitous" being suitable for use in the present invention is very optimistic.
Further, for a specific space such as a sentry box, a suction pump with a stronger downward direction in a working area is adopted, a door for entering and exiting and a window for sampling are also adopted, the suction pump with a downward direction in the middle when the window is opened is also adopted, and the suction pump is automatically closed when the window is closed, so that the possibility of mutual infection of people directly or indirectly through air flow can be avoided.
Further, "micro negative pressure modification" of "specific space" of public facilities or non-public facilities in a broad sense can follow the above mode, namely, the "up-blowing and down-sucking" air circulation mode, not only limited to "negative pressure emergency ambulance" or "negative pressure ward", but also uniformly carries out the "harmless discharge" mode after disinfection for the air flow discharged by "down-sucking".
Compared with the prior art, the invention adopts the air circulation mode of ' up-blowing and down-sucking ', changes the traditional air circulation mode of ' up-sucking and down-blowing ' which is necessary for ' hot air rising ', ensures that people communicate with people without the mode of ' wearing mask ' (only for ' double insurance '), can fully exert the mode in public places such as ' buses ', ' postal wheels ', ' gymnasiums ', ' restaurants ', ' classrooms ', and the like without deliberately avoiding, and particularly can ' easily cope with ' small-sized ' special spaces ' such as ' sentry pavilion ' for ' making ' nucleic acid detection ', and is the most ideal and economic scheme for resisting respiratory diseases such as ' new coronavirus ' in the current stage by constructing or modifying the ' special space ' facilities by the means.
Drawings
FIG. 1 is a schematic diagram of a sentry box type "micro negative pressure" facility of the present invention.
Fig. 2 shows a schematic view of the "negative pressure" of the present invention applied to "motor car".
In FIG. 1, 101-a specific sentry box for "nucleic acid detection", 102-a working "window", 103-an air suction head, 104-a downward suction air flow channel, 105-an upper air supply "air inlet", 106-an air filtration and disinfection area, 107-a working window air flow direction, and 108-a lower air flow direction extension section air outlet; in fig. 2, 201 denotes "strip-shaped air inlets" at the lower end of the vehicle cabin, 202-upper-end air inlets, 203-the direction of air flow in the vehicle cabin.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example 1A "micro negative pressure" modification scheme of "particular space" for "nucleic acid sampling" by "sentry box" type
See fig. 1: 101-a specific sentry box for 'nucleic acid detection', 102-a working 'window', 103-an air suction head, 104-a downward air suction and flow pipeline, 105-an upper air supply 'air inlet', 106-an air filtration and disinfection area, 107-a working window air flow direction, and 108-a lower air flow direction extension section air outlet of a suction pump;
the worker opens the working window 102 in the special space 101 of the sentry box, at this time, the suction head 103 starts working through the air outlet 108 of the extension section of the lower suction pump and the downward suction air flow pipeline 104, so that no air exchange (infection) can occur between the worker and the detected person, because the air flow direction 107 is directly sucked downwards by the suction pump, and the small door of the inlet and outlet of the special space of the sentry box has the same effect as the working window (namely, the suction pump instantly has downward suction force when the door is opened, so that the outside air can not enter the special space), so that the sentry box can be in a micro negative pressure state during working.
Example 2 a "negative pressure" modification of "motor car" ("negative pressure" modification of "bus" and "same as" thunder "):
as can be seen from fig. 2, the "suction pump" of the "suction" 201 is disposed at the bottom of the cabin, and forms the "air circulation" direction of the "top-down" 203 by the "air supply pipe" 202 above the cabin, and the air flow after the "suction" is filtered by the "disinfection tank" at the bottom of the cabin and then discharged, so that for each passenger in the cabin, there is a relatively strong "downward air flow" in the space, and there is no possibility that the people are "virus-infected" each other by air. Such a modification makes it possible to make a "safety" for diseases that depend on air infection "that can be" excluded "[ its" downdraft "can be" automatically "or" it is dynamically "adjusted to" optimal state "(the so-called" optimal state "is that the" suction pump "power can be automatically adjusted according to the people's flow density) ].
The above description of a specific space facility for constructing micro negative pressure provided by the present invention has been provided in detail, and specific examples are applied herein to illustrate the principles and embodiments of the present invention, and the above examples are only for helping to understand the method and core idea of the present invention; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present invention, the present description should not be construed as limiting the present invention in view of the above.
