Description

TECHNICAL FIELD

[0001] The utility model belongs to air purification technical field, concretely relates to a flat epidemic conversion type high -efficient exhaust port. BACKGROUND

[0002] High -efficient exhaust port is the necessary air purification treatment device in infectious disease hospital, flat epidemic combination hospital and laboratory, and the high -efficient exhaust port commonly used at present basically only has one passageway. Among them, the high -efficient exhaust port is installed on the ventilation passageway, and the air passing through the high -efficient exhaust port is purified in the epidemic or certain specific air treatment.

[0003] However, when the epidemic is not or the exhaust does not need high -efficient filtration, the filter often needs to be removed and stored in the suitable position, which not only wastes labor, but also occupies the site, and there is a certain virus exposure risk when the filter is removed. If the high -efficient filter is not removed, when the exhaust does not need to pass through the high -efficient filter for treatment, the energy consumption of the exhaust system is increased, and waste is caused. INVENTION CONTENTS

[0004] The utility model discloses a flat epidemic conversion type high -efficient exhaust port.

[0005] The utility model discloses the technical scheme that the technical problem is solved is: a flat epidemic conversion type high -efficient exhaust port, including the box, the box is equipped with epidemic time passageway and flat time passageway, installs high -efficient low -resistance filter in epidemic time passageway, and the top of the box is equipped with epidemic time passageway switch valve and flat time passageway switch valve, is respectively used to control the switch of epidemic time passageway and flat time passageway.

[0006] Specifically, the box is installed with the wind baffle, to shield epidemic time passageway and flat time passageway.

[0007] Specifically, the top of the epidemic time passageway is equipped with the disinfection air inlet.

[0008] Specifically, the top of the box is equipped with the pressure difference table.

[0009] The utility model has the following beneficial effects:

[0010] 1) the utility model can meet the requirement of using under the epidemic and flat time working condition, and does not need to remove, transport and store manually when the high -efficient filter is not used;

[0011] 2) the disinfection air inlet meets the disinfection requirement in situ, can meet the disinfection requirement when the high -efficient filter is not used, and guarantees the air safety under flat time working condition;

[0012] 3) flat time passageway and epidemic time passageway switch valve can switch flat time passageway and epidemic time passageway, effectively meet the requirement of reducing the energy consumption of exhaust system under flat time working condition.

[0013] 4) Through the structural design, the flat epidemic conversion type high-efficiency exhaust port can save operation and maintenance labor, reduce use cost, and guarantee air safety during the epidemic, effectively overcoming the problems of operation and maintenance cost increase, virus exposure risk and inability to reduce exhaust energy consumption under normal working conditions caused by air filtration in the prior art. BRIEF DESCRIPTION OF DRAWINGS

[0014] Figure 1 It is a structural schematic view of the utility model.

[0015] In the figure: 1 - wind baffle; 2 - box; 3 - normal passage; 4 - normal passage on-off valve; 5 - differential pressure gauge; 6 - epidemic passage on-off valve; 7 - disinfection air inlet; 8 - epidemic passage; 9 - high-efficiency low-resistance filter. DETAILED DESCRIPTION

[0016] The utility model will be further described in detail in combination with the drawings.

[0017] As Figure 1 shown, a flat epidemic conversion type high-efficiency exhaust port, comprising a box 2, a high-efficiency low-resistance filter 9, a normal passage on-off valve 4 and an epidemic passage on-off valve 6, the box 2 is provided with an epidemic passage 8 and a normal passage 3, the epidemic passage 8 is installed with the high-efficiency low-resistance filter 9, which is used for filtering and treating the exhaust air passing during the epidemic, and the normal passage 3 is used as the exhaust passage during normal operation.

[0018] The high-efficiency low-resistance filter 9 is used for treating the exhaust air or air in a specific area during the epidemic.

[0019] The normal passage on-off valve 4 and the epidemic passage on-off valve 6 are used for switching the normal passage 3 and the epidemic passage 8.

[0020] The disinfection air inlet 7 is used for the in-situ disinfection demand of the high-efficiency low-resistance filter 9.

[0021] The normal passage on-off valve 4 and the epidemic passage on-off valve 6 are both the structure of a pair of multi-leaf valves.

[0022] The use method of the utility model: when used normally, open the normal passage on-off valve 4 and close the epidemic passage on-off valve 6, at this time, air enters the normal passage 3 from the wind baffle 1 and is discharged from the normal passage on-off valve 4; when used during the epidemic, open the epidemic passage on-off valve 6 and close the normal passage on-off valve 4, at this time, air enters the epidemic passage 8 from the wind baffle 1 and is discharged from the epidemic passage on-off valve 6 through the high-efficiency low-resistance filter 9.
