Description

Technical Field

[0001] This invention relates to the field of mushroom cultivation technology, and in particular to an air circulation and purification system for a mushroom bottling workshop. Background Technology

[0002] In the industrialized, mass production of edible fungi, cultivation bottles are commonly used as cultivation containers. To improve production efficiency and reduce costs, waste inside the bottles needs to be cleaned quickly after harvesting to achieve recycling. Currently, the mainstream cleaning process combines a scraper with high-pressure air blowing for physical removal of waste from the cultivation bottles.

[0003] However, the aforementioned cleaning methods have significant drawbacks. Under the action of the excavator and high-pressure air blowing, a large number of edible fungal spores, miscellaneous molds, and other microorganisms in the waste material escape from the bottles and mix with the culture medium dust generated during bottle excavation, forming a high concentration of gaseous-solid mixed pollutants. These pollutants diffuse within the bottle excavation workshop, causing severe deterioration of the workshop's air quality and posing a direct threat to the respiratory health of operators. In the short term, workers may experience allergic reactions or respiratory irritation due to inhalation of mold, spores, and dust; long-term exposure may increase the risk of chronic bronchitis, allergic pneumonia, and even fungal infections. Furthermore, because traditional workshops typically use direct exhaust air exchange, these pollutants are discharged outdoors without effective treatment, causing pollution to the factory area and surrounding environment. Summary of the Invention

[0004] The main objective of this invention is to provide an air circulation and purification system for a mushroom bottling workshop, in order to solve the problem of severe air pollution in existing bottling workshops.

[0005] According to an embodiment of the present invention, an air circulation and purification system for a bottling workshop of edible fungi is provided to create a negative pressure environment in the workshop. The system includes: a first air collection unit, comprising an air collection hood covering a bottling machine on the production line; a second air collection unit, comprising air collection ports located around the production line; an air collection passage unit, the air collection passage unit being connected to the air collection hood of the first air collection unit and the air collection ports of the second air collection unit; and a purification unit, the purification unit comprising an air inlet and an air outlet. The air inlet of the unit is connected to the air collection passage unit. The purification unit purifies the mold, spores and dust contained in the air collected by the first air collection unit and the second air collection unit by physical means. The air supply unit includes an air inlet and an air outlet. The air inlet of the air supply unit is connected to the air outlet of the purification unit. The air outlet of the air supply unit is located in the bottle-digging workshop. When the first air collection unit, the second air collection unit and the air supply unit are running together, the air pressure in the bottle-digging workshop is lower than the external ambient air pressure.

[0006] The air intake volume of the first air collection unit and the second air collection unit is greater than the air output volume of the air supply unit.

[0007] The purification unit is a water vortex wet purification device.

[0008] The water cyclone wet purification device includes a negative pressure fan connected to the gas collection passage unit and a positive pressure fan connected to the air supply unit.

[0009] The gas collection hood includes a top wall and side walls. The top wall of the gas collection hood is provided with an air intake. The gas collection passage unit includes a gas collection pipe, and the air intake is connected to the gas collection pipe.

[0010] At least a portion of the sidewall of the gas collection hood is made of a transparent material.

[0011] The gas collection hood is also provided with an operating door on its side wall, and the operating door is movably connected to the gas collection hood.

[0012] The gas collection hood has channels on its opposite side walls for the water supply line to pass through.

[0013] The bottom of the gas collection hood is an open structure, and a waste inlet and a waste collection chamber are correspondingly provided below the gas collection hood.

[0014] The second gas collection unit further includes a gas collection port disposed in the waste collection chamber and located around the waste inlet.

[0015] According to the technical solution of the present invention, by setting up a gas collection hood for each bottle-digging machine and collecting the air around the production line, the collected air is purified and then transported back to the workshop. At the same time, the air pressure in the bottle-digging workshop is lower than the external ambient air pressure. This application can not only continuously and cyclically purify the workshop air, significantly reduce the concentration of suspended solid pollutants in the workshop and improve the working environment of the staff, but also effectively prevent pollutants in the workshop from leaking outwards, avoiding pollution to the factory area and the surrounding environment.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] According to an embodiment of the present invention, an air circulation and purification system for use in a mushroom cultivation bottle removal workshop is provided. In this embodiment, the mushroom cultivation bottle removal workshop includes a bottle removal room and a waste collection chamber. The bottle removal room is located on the second floor of the workshop. Multiple production lines and multiple bottle removal machines are set up in the bottle removal room. Each bottle removal machine can perform knife separation, inverting, or high-pressure air blowing on the culture medium in the harvested cultivation bottles to remove the culture medium waste from the bottles. However, small-diameter solid pollutants such as mold, spores, and dust in the culture medium waste will be stirred up during the cleaning process, affecting the air quality of the workshop. The waste collection chamber is located on the first floor of the bottle-removing workshop. The waste collection chamber and the bottle-removing workshop are connected by multiple waste outlets that run through the floor of the bottle-removing workshop and the ceiling of the waste collection chamber. Each waste outlet is located below the corresponding bottle-removing machine. The culture medium waste cleaned up by the bottle-removing machine can fall directly into the waste collection chamber through the waste outlet. During the falling process, solid pollutants such as mold, spores and dust in the culture medium waste will also be raised again and dispersed into the air, further aggravating the spread of pollutants in the waste collection chamber and even the entire workshop.

[0024] To address this issue, this embodiment of the invention installs an air circulation and purification system in the edible mushroom bottling workshop to purify the air within the workshop from pollutants. (Reference) Figure 1The air circulation and purification system includes: a first air collection unit 10, a second air collection unit 20, an air collection passage unit 30, a purification unit 40, and an air supply unit 50. The first air collection unit 10 collects point-source solid pollutants, while the second air collection unit 20 collects diffuse solid pollutants. The first and second air collection units 10 and 20 are connected to the purification unit 40 via the air collection passage unit 30. The purification unit 40 purifies the solid pollutants contained in the workshop air collected by the first and second air collection units 10 and 20. The purification unit 40 is also connected to the air supply unit 50, which returns the purified air to the bottle-digging workshop, thus achieving air circulation.

[0025] The first gas collection unit 10, also known as the bottle-digging machine gas collection unit, is used to collect point source pollution generated by the bottle-digging machine. (Refer to the reference...) Figure 2 and Figure 3 The first gas collection unit 10 includes gas collection hoods 11, the number of which matches the number of bottle-removing machines. The gas collection hoods 11 are positioned above the bottle-removing machines to collect most of the solid contaminants stirred up during the emptying of the cultivation bottles. Each gas collection hood 11 is a semi-enclosed space with an open bottom, comprising a top wall 111 and four side walls 112. An air intake 113 is provided on the top wall 111. In the working direction of the production line, two opposite side walls 112 of the gas collection hood 11 have passageways 114 through which the production line carries the cultivation bottles in and out of the gas collection hood 11. Operating doors 115 are installed on at least one side wall 112 on both sides of the production line to allow for maintenance, cleaning, or adjustment of the bottle-removing machines within the gas collection hood 11. The operating doors 115 may be hinged doors hinged to the gas collection hood 11 or sliding doors that open and close on the gas collection hood 11. Furthermore, at least a portion of at least one sidewall 112 of the gas collection hood 11 is made of a transparent material to allow operators to observe the bottle-digging operation.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The second gas collection unit 20, also known as the workshop gas collection unit, includes a gas collection port (first gas collection port) located in the bottle-digging room and a gas collection port (second gas collection port 21) located in the waste collection chamber. The first gas collection port can be located in the space around the bottle-digging room assembly line or on the top wall of the bottle-digging room to collect solid contaminants escaping from the gas collection hood 11. The number of first gas collection ports can be equal to the number of assembly lines. The second gas collection port 21 can be located around the waste outlet in the waste collection chamber to collect solid contaminants escaping during the fall of waste.

[0027] The air collection passage unit 30 includes an air collection pipe, and the purification unit 40 includes an air inlet and an air outlet. The air inlet of the air collection pipe can be connected to both the air collection hood 11 and the air collection port, and the air outlet of the air collection pipe is connected to the air inlet of the purification unit 40. Specifically, refer to the reference... Figures 2-4 The gas collection pipeline includes a first gas collection pipeline 31, a second gas collection pipeline, and a third gas collection pipeline 32. The first gas collection pipeline 31 is connected to the air intake 113 of the gas collection hood 11, the second gas collection pipeline is connected to the first gas collection port located in the bottle removal room, and the third gas collection pipeline 32 is connected to the second gas collection port 21 located in the waste collection chamber. To ensure the overall purification effect of the workshop air and to ensure the uniform distribution of airflow at each air intake or gas collection port, the cross-section of the gas collection pipeline gradually increases along the airflow direction (i.e., from the air inlet to the air outlet). Taking the third gas collection pipeline 32 as an example, continue to refer to... Figure 4 In this embodiment, there are four waste inlets. The third air collection pipe 32 extends along both sides of the waste inlets. Each side of the third air collection pipe 32 includes four pipe sections 321-324 and four second air collection ports 21 located on the four pipe sections and corresponding to the positions of the waste inlets. The pipes 324 on both sides converge into a pipe 325, which connects to the air inlet of the purification unit 40. To meet the required airflow and velocity for air circulation, appropriate dimensions can be matched for different pipe sections and the second air collection ports 21 according to the parameters listed in the table below:

[0028]

[0029] In one embodiment of this application, the waste collection compartment is further provided with a door for transporting waste. This door remains closed during normal workshop operation to maintain airtightness and is only opened when waste is being removed. To avoid the risk of solid pollutants escaping when the door is opened and to enhance the collection of exhaust gas during workshop operation, a dedicated air intake vent 22 is specially provided above the door. The air intake vent 22 is connected to the purification unit 40 via a gas collection pipe. The wind speed at the air intake vent 22 can be 9 m / s. When the door is closed, the air intake vent 22 can effectively supplement the second gas collection vent 21, enhancing the collection of solid pollutants that may leak near the door gap; when the door is open for waste removal, the air intake vent 22 can form an air curtain at the open door, separating the waste collection compartment from the external environment and preventing solid pollutants in the waste collection compartment from spreading into the external environment.

[0030] Continue to refer to Figure 1The purification unit 40 physically deposits solid pollutants such as mold, spores, and dust contained in the air. In this embodiment, the purification unit 40 may be one or more water cyclone wet purification devices, which include a negative pressure fan, a purification chamber, and a positive pressure fan. The negative pressure fan is located at the air inlet of the water cyclone wet purification device and is connected to the air outlet of the air collection pipeline. The positive pressure fan is located at the air outlet of the water cyclone wet purification device and is connected to the air supply unit 50. The negative pressure fan delivers air from the air collection hood 11 and the bottle-digging workshop to the purification chamber. The purification chamber is equipped with a multi-stage water cyclone vortex structure. The solid pollutants contained in the collected air come into full contact with, collide with, and are captured by high-speed rotating droplets in the purification chamber, and are finally separated from the air and deposited in the water.

[0031] The air supply unit 50 includes an air inlet and an air outlet. The air inlet of the air supply unit 50 is connected to the air outlet of the purification unit 40. The air outlet of the air supply unit 50 is located in the bottle-digging workshop. Specifically, the air outlets of the air supply unit 50 are provided in both the bottle-digging workshop and the waste collection chamber. The air outlets of the air supply unit 50 can be located on the side walls of the bottle-digging workshop and the waste collection chamber so as to send the purified air back to the bottle-digging workshop to achieve air circulation and purification in the workshop.

[0032] In practice, the doors and windows of the bottle-digging workshop are kept sealed. The air circulation and purification system is activated before starting the bottle-digging production line. Once the air circulation and purification system is activated, the first air collection unit 10 and the second air collection unit 20 simultaneously draw air from the bottle-digging workshop. The drawn air enters the purification unit 40 for water vortex purification. The purified air is then returned to the workshop by the air supply unit 50. By changing the fan frequencies of the positive and negative pressure fans, the air intake of the first air collection unit 10 and the second air collection unit 20 is set to be slightly greater than the air output of the air supply unit 50. This results in the air pressure inside the bottle-digging workshop being lower than the external ambient air pressure, creating a slightly negative pressure environment. This prevents air from leaking out of the bottle-digging workshop, thus avoiding pollution of the factory area and surrounding environment.

[0033] According to embodiments of this application, by adding an air circulation and purification system to the edible mushroom bottle-digging workshop, the air circulation and purification system includes an air collection unit for collecting workshop air, a purification unit for purifying the collected air, and an air supply unit for returning the purified air to the workshop. This eliminates the source-level dispersion of pollutants such as mold, spores, or dust in the workshop or their direct emission into the atmosphere, solving the pollution problem of edible mushroom cultivation factories on the factory area and surrounding environment, resulting in significant environmental benefits. By setting up a first air collection unit and a second air collection unit, the first air collection unit achieves efficient source-level collection of high-concentration solid pollutants generated during the bottle-digging machine's operation through an air collection hood; the second... The second gas collection unit collects dispersed solid pollutants in the workshop, significantly improving the efficiency of pollutant collection and air purification, and fundamentally improving the air quality in the workshop. By setting the purification unit as a water vortex wet purification device, which not only has high purification efficiency for airborne solid pollutants, but can also simultaneously absorb some soluble odor gases, a slight negative pressure environment is created in the workshop by setting the air intake volume of the first and second gas collection units to be greater than the air output volume of the air supply unit. This prevents pollutants from leaking out of the workshop and further reduces the impact of the edible mushroom bottling workshop on the external environment, reflecting the modern environmentally friendly concept of prevention from the source and treatment throughout the entire process.
