Description

Technical Field

[0001] This utility model relates to an air purification system, and more particularly to an air purification and smoke exhaust system. Background Technology

[0002] Currently, the catering industry, represented by hot pot and barbecue restaurants, generally adopts centralized fume capture and emission systems. Commonly used systems include single-table capture systems: using upward-suction umbrella-shaped fume hoods (capture efficiency of about 60-75%) or downward-suction fume collection devices (capture efficiency of about 55-70%), which centrally transport the fumes to the rooftop purification unit through ducts, and then discharge them at high altitude after electrostatic dust removal or activated carbon adsorption; environmental control systems: relying on central air conditioning systems for temperature and humidity regulation, without dedicated water vapor treatment devices; and operation control systems: using fixed-frequency fans for constant airflow operation, without establishing a pollutant concentration feedback and adjustment mechanism.

[0003] Even after purification, oil fume pollutants cannot be directly discharged outdoors due to environmental factors in residential areas. As a result, oil fume and odor problems remain significant in hot pot restaurants, and in severe cases, they can escape through windows, leading to complaints from residents. Furthermore, during peak dining hours, oil fumes escaping from tables are difficult to control, increasing indoor pollutant concentrations and impacting the dining environment. Traditional capture methods have a 20%-30% escape rate, which needs improvement. Additionally, the continuous boiling of hot pot generates a water vapor load of 300g / h-500g / h per table, while traditional air conditioning dehumidifies at only 40%-50% efficiency, resulting in condensation of 0.5-1.2L / m²•h on the ceiling. This leads to a damp indoor environment, causing the ceiling to become moldy and prone to mildew growth, posing hygiene risks and harming customer health. Utility Model Content

[0020] Figure 2 This is a schematic diagram of the purification system according to an embodiment of the present utility model;

[0021] Figure 3 This is a schematic diagram of the dehumidification module according to an embodiment of the present invention. Detailed Implementation

[0022] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0023] Example 1

[0024] like Figure 1 As shown, the air purification and smoke exhaust system of this embodiment includes:

[0025] The purification system includes a first duct 10 and a purification module 100 disposed in the first duct for purifying oil fumes in the air;

[0026] The dehumidification system includes a second duct 20 and a dehumidification module 200 disposed in the second duct for removing moisture from the air;

[0027] The air inlet 11 of the first pipe is located near the air outlet 22 of the second pipe, and the air inlet 21 of the second pipe is located near the air outlet 12 of the first pipe.

[0028] At least two parallel ducts are installed in the ceiling, each containing a built-in purification module and a dehumidification module. The airflow in the two ducts is opposite, with the air inlet of the first duct near the air outlet of the second duct, and the air outlet of the second duct near the air inlet of the first duct. The two purification devices draw air in from both sides of the room and exhaust it at the other end, achieving air circulation and purification. These two ducts can also purify water vapor and cooking fumes, achieving overall indoor air quality control.

[0029] Furthermore, such as Figure 2 As shown, the purification module includes a filter device, a first fan 101, and a purification unit. The purification unit includes activated carbon 102. The activated carbon captures, removes, or concentrates impurities, pollutants, and odor molecules in gases and liquids through physical adsorption and partial chemical adsorption. Of course, those skilled in the art will understand that the purification unit may also include other modules, which can be configured as needed. The purification module also includes an oil pan 103 located at the bottom.

[0030] Furthermore, the filtration device includes filter cotton and a filter screen. A fan is used to promote airflow within the duct, achieving air circulation and making it easier for the duct to capture indoor fumes and moisture.

[0031] Furthermore, the filter screen includes at least one of a stainless steel washable mesh 104, a particulate filter, and an activated carbon filter. Different filter screens perform different functions, and those skilled in the art can adjust their positions and quantities as needed to improve the purification function of the purification module.

[0032] Furthermore, such as Figure 3As shown, the dehumidification module includes a condenser 201, an evaporator 202, and a second fan 203. Preferably, the front of the dehumidification module also includes a filter 204, which filters the intake air. The condenser 201 cools and dehumidifies the air. The condenser 201 is connected to the compressor 205, and the air is then reheated and discharged after passing through the evaporator 202, ensuring that the discharged air is consistent with the indoor temperature. The fan is used to circulate the air and promote airflow.

[0033] Furthermore, the air purification and smoke extraction system also includes a humidity sensor connected to the dehumidification module. This humidity sensor is positioned approximately 2 meters indoors. When the indoor temperature exceeds 55% RH, the dehumidification module activates. When the detected humidity level is below 55% RH, the dehumidification module can be shut down to reduce the overall system's energy consumption. Here, RH represents the current relative humidity.

[0034] Furthermore, the air purification and smoke exhaust system also includes a particulate matter (PM) sensor and a total volatile organic compound (TVOC) sensor.

[0035] Furthermore, the air purification and smoke extraction system also includes a display device and a main control device. The main control device is connected to the purification module, the dehumidification module, and various sensors, and is used to display various parameters on the display device. The display device can simultaneously display operating parameters such as equipment wind speed and power, and can promptly arrange cleaning and maintenance when data is abnormal. It can also display the cleaning time limit for the stainless steel mesh of the purification module and the replacement time limit for the particulate matter and activated carbon filters in real time, reminding the supplier to replace them when the cleaning and maintenance time is reached. It can also be used for fault monitoring.

[0036] The main control device is also used to adjust the output power of the purification module's fan according to the indoor conditions. For example, the air volume of the purification module's fan is output according to Q=K×N×Qn, where K is the air volume compensation coefficient, which can be 1.2; Qn is the unit demand air volume specified according to a single pollution source in the room, such as the air volume required for a single table of diners in a hot pot restaurant; and N is the number of pollution sources. Therefore, for example, when 0-13 tables are dining, the power output corresponds to 10%-70% respectively. When the pollutant concentration exceeds the set concentration, additional compensation power P is output. 补 =[(C 颗粒物 -C 设 ) / C 设 +(C TVOCs -C 设 ) / C 设 ]×30%×P 额定 The maximum compensation power can reach 30% × P额定 Among them, P 额定 This is the rated maximum power.

[0037] The air purification and smoke exhaust system of this embodiment can be set up with the above-mentioned purification system and dehumidification system as a group, and multiple groups of the purification system and dehumidification system can also be set up. That is, multiple pipes can be arranged in the upper part of the room, with two pipes as a group, and multiple groups can be arranged side by side or perpendicular to each other.

[0038] The air purification and smoke exhaust system disclosed herein utilizes the staggered relative arrangement of the air inlets and outlets of the purification system and the dehumidification system. That is, the air inlet of the purification system is close to the air outlet of the dehumidification system, and the air inlet of the dehumidification system is close to the air outlet of the purification system. This achieves the goal of circulating and purifying indoor air even when indoor air is not exhausted, thus enabling overall regulation of indoor air.
