Description

Technical Field

[0001] This utility model relates to the field of air shower technology, and in particular to an energy-saving air shower. Background Technology

[0002] An air shower is a purification device that removes dust from the surface of personnel or objects using a high-speed airflow. It is widely used in industries with stringent cleanliness requirements, such as electronics, pharmaceuticals, food, and biological laboratories. Its core function is to prevent contaminants from entering the clean area, ensuring the cleanliness of the production environment.

[0003] Traditional air showers have the following drawbacks:

[0004] High energy consumption: The continuous operation of the fan consumes a lot of electricity, and the direct discharge of exhaust air results in energy waste;

[0005] Single function: It is only used for personnel / material air showering and does not consider the reuse of residual air. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0007] Therefore, one objective of this utility model is to propose an energy-saving air shower to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0008] To achieve the above objectives, one embodiment of the present invention provides an energy-saving air shower room, including a chamber body, a fan, and a filter. The fan is installed on the top of the chamber body, and the air outlet of the fan is connected to the interior of the chamber body.

[0009] The air inlet of the fan is equipped with a filter, and doors are installed on both sides of the chamber.

[0010] The interior of the chamber is equipped with several nozzles, which are opened horizontally.

[0011] A flange is installed on the outside of the other side of the chamber, and a conical flow guide is fixedly connected to the outside of the chamber through the flange;

[0012] The end of the conical air guide is fixedly connected to a transition port, the diameter of which gradually decreases, returns to a constant value, and then returns to its original shape.

[0013] The end of the transition port is detachably connected to a straight connector, which is connected to the air outlet of the bathroom.

[0014] Preferably, of any of the above options, the chamber is made of stainless steel and the fan is installed vertically.

[0015] Using the above technical solution: This air shower room includes:

[0016] Chamber: Made of stainless steel, with a vertical fan installed at the top and tempered glass doors on both sides;

[0017] Nozzle system: Two sets of horizontal nozzles are installed on the inner wall of the chamber. Each set of nozzles is connected to a fan to form a high-speed airflow to spray personnel / materials.

[0018] Airflow recovery assembly: The outer side of the chamber is connected to a conical air guide hood, a venturi tube-type transition port and a detachable straight connector via a flange, and finally connected to the bathroom air outlet.

[0019] Preferably, as described in any of the above schemes, the fan consists of a centrifugal fan and a drive motor.

[0020] Preferably, in any of the above embodiments, the door has a tempered glass panel, and the nozzles are divided into two groups, each group connected to a fan.

[0021] Excess wind diversion and energy recovery

[0022] Conical air deflector: The inner diameter gradually decreases, converging the airflow from the air shower into a high-speed directional airflow;

[0023] Venturi tube transition port: Utilizing the Venturi effect, negative pressure is generated in the narrow section of the transition port to further accelerate airflow and reduce energy loss;

[0024] Straight connector: Uses flange connection to ensure a sealed connection with the bathroom ventilation duct and prevent air leakage.

[0025] Preferably, in any of the above schemes, the inner diameter of the conical guide shield decreases sequentially, and the transition port is specifically a Venturi tube.

[0026] Primary purification: The fan draws in air from the air inlet, purifies it through the filter, and then forms a clean airflow through the nozzle to complete the shower.

[0027] Secondary use: The airflow after the shower carries a small amount of particles, which are accelerated by the guide hood and transition port, and then delivered to the bathroom at a better wind speed, replacing the traditional exhaust fan and achieving ventilation.

[0028] Energy Saving Verification: Actual tests show that a single air shower can provide sufficient ventilation for a restroom with an area of ​​≤20㎡, saving 1.5kW / day of independent fan power consumption. Energy Consumption Comparison: In the traditional solution, the air shower + restroom requires two fans with a total power of 4kW; this invention only requires a 2.8kW air shower fan, resulting in significant energy savings.

[0029] Preferably, in any of the above embodiments, the straight connector is connected to the transition port via a flange.

[0030] The above technical solution is adopted: a stainless steel chamber is installed in the clean room, a centrifugal fan is fixed on the top, and the nozzles are divided into two groups, left and right, corresponding to two fans respectively;

Hygiene standard test: the number of airborne particles in the bathroom air ≤1000 particles / m³, meeting the GB / T 18883 indoor air quality standard.

[0034] Cost calculation: When the factory is equipped with 10 air showers, the annual electricity cost will be saved by about 20,000 yuan.

[0035] Suitable for scenarios such as food factories and electronics factories that require both clean production and ventilation in auxiliary areas.

[0036] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0037] This energy-saving air shower, through the coordinated design of nozzles, flanges, conical guide hoods, transition ports, and straight connectors, achieves the following: Primary purification: Air is drawn in by the fan, purified by a filter, and then blown through the nozzles to form a clean airflow. Secondary utilization: The airflow after blowing, carrying a small amount of particulate matter, is accelerated by the guide hood and transition port and then delivered to the restroom at a better wind speed, replacing traditional exhaust fans and achieving ventilation. A single air shower can provide sufficient exhaust air for a restroom with an area of ​​≤20㎡, saving 1.5kW / day of independent fan power consumption. Energy consumption comparison: Traditional solutions require two fans for the air shower + restroom, with a total power of 4kW; this invention only requires a 2.8kW air shower fan, resulting in significant energy savings.
