The main shortcomings of pressure-type ventilation are as follows:

[0003] First, as the length of tunnel excavation increases, the ventilation resistance increases accordingly, and the energy consumption of the ventilator increases significantly. When the air duct and its accessories are improperly laid, insufficiently maintained or untimely repaired, the effective air supply in the air duct drops sharply, and the ventilation effect and the air quality in the tunnel deteriorate.

[0026] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] like Figures 1 to 5 As shown, the utility model provides an integrated automatic dust removal type jet dehumidification unit, including a shell and an automatic control system 7, an upper cavity and a lower cavity are formed inside the shell, a silencer static pressure box 3 is provided in the upper cavity, a jet device is provided on the silencer static pressure box 3, a dehumidification device is installed in the upper cavity, an automatic dust removal device is installed in the lower cavity, and the automatic control system 7 is electrically connected to the jet device, the dehumidification device and the automatic dust removal device.

[0030] In some preferred embodiments, the jet device includes a plurality of jet nozzles 1, and the jet nozzles 1 are evenly arranged around the muffler static pressure box 3. The diameter of the jet nozzle 1 is 5mm-20mm. The height of the shell is greater than the diameter of the shell, and the entire shell is "thin and tall". Because stainless steel has the characteristics of corrosion resistance, the shell is made of stainless steel to extend the service life.

[0031] In some preferred embodiments, the automatic dust removal device includes an EC fan 2, a primary filter device 8, a secondary filter device 9, a soot blowing rotor 12 and an ash hopper 10, the EC fan 2 is arranged in the upper cavity and located on the top of the soot blowing rotor 12, the primary filter device 8 is arranged on the outside of the lower cavity, the secondary filter device 9 is arranged in the lower cavity, the soot blowing rotor 12 is arranged on the top of the secondary filter device 9, and the ash hopper 10 is arranged at the bottom of the secondary filter device 9.

[0032] In some preferred embodiments, the primary filter device 8 comprises an air intake grille and a filter screen, wherein the air intake grille is arranged outside the filter screen. The secondary filter device 9 adopts a PTFE membrane filter cartridge. The secondary filter device 9 is provided with at least one group.

[0033] PTFE air purification membrane is made of polytetrafluoroethylene. After expansion and stretching, it forms a microporous film. This film is laminated on various fabrics and substrates with a special process to become a new type of filter material. The membrane has a small pore size (0.05-0.45μm), uniform distribution, and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve the purpose of purification and ventilation. It is widely used in the fields of pharmaceuticals, biochemistry, microelectronics, and laboratory consumables.

[0034] In some preferred embodiments, the dehumidification device includes a compressor 11, an evaporator 4, a condenser 5 and a liquid reservoir 6, wherein the compressor 11 is used to provide power to compress the low-temperature and low-pressure steam refrigerant into high-temperature and high-pressure refrigerant vapor; the condenser 5 is used to cool the high-temperature and high-pressure refrigerant vapor into a high-pressure liquid refrigerant and release heat; the evaporator 4 is used to evaporate the high-pressure liquid refrigerant into a low-temperature and low-pressure steam refrigerant and absorb heat from the air, and the liquid reservoir 6 is used to store excess refrigerant caused by load changes in the refrigeration system.

[0035] like Figure 5 As shown, it is a flow chart of the refrigeration cycle. The refrigerant vapor coming out of the evaporator 4 is sucked into the compressor 11, compressed into a high-temperature and high-pressure gas, and enters the condenser 5 for condensation. The heat of the refrigerant is taken away by the air and condensed into a high-pressure liquid. After passing through the drying filter of the liquid storage tank 6, it enters the thermal expansion valve (not shown in the figure) for throttling and pressure reduction, and becomes a low-temperature and low-pressure refrigerant saturated liquid. Then it enters the evaporator 4 to absorb the heat in the wet air and evaporates into refrigerant vapor, and enters the gas-liquid separator (not shown in the figure) for gas-liquid separation. The refrigerant vapor is sucked into the compressor 11 for compression, thereby completing a refrigeration cycle.

[0036] The compressor 11 provides power to compress the low-temperature and low-pressure steam refrigerant into high-temperature and high-pressure refrigerant vapor; the condenser 5 cools the high-temperature and high-pressure refrigerant vapor into high-pressure liquid refrigerant and releases heat; the evaporator 4 evaporates the high-pressure liquid refrigerant into low-temperature and low-pressure steam refrigerant and absorbs heat from the air. The three work together to realize the refrigeration cycle of the dehumidification device. The working principle of the evaporator 4 is essentially to exchange heat between the high-pressure liquid refrigerant and the air, causing it to evaporate into low-temperature and low-pressure steam refrigerant, thereby reducing the indoor air temperature and achieving the refrigeration effect of the air-conditioning system.

[0037] The working principle of the utility model is as follows: the damp and dusty air on the working surface is automatically filtered and dusted through the air intake grille, the filter screen, and the PTFE coated filter cartridge, and then sucked into the unit by the EC fan 2. The damp air after automatic dust removal is dehumidified by the evaporator 4 and the condenser 5 and then pressed into the silencer static pressure box 3. The clean and dry air is silenced and then ejected toward the working surface by the jet nozzle 1, covering, controlling and improving the air quality of the working surface. After taking away the damp and dusty air on the working surface, it is sucked into the unit by the air intake grille and the filter screen for circulation treatment.

[0038] The moist air that has been automatically filtered and dusted by the PTFE coated filter cartridge is sucked into the unit by the EC fan 2, condensed and dehumidified by the evaporator 4, and then enters the condenser 5 for heating. The dry air is ejected toward the working surface through the jet nozzle 1 on the side of the silencer static pressure box 3.

[0039] This unit changes the traditional forced ventilation mode and introduces the concept of "distributed centralized treatment and jet environment control". It automatically removes dust and dehumidifies the dusty and humid air on the construction surface and uses the jet control air field theory to comprehensively improve the air quality of the construction surface, protect the physical and mental health of construction workers, and improve construction efficiency.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
