An indoor formaldehyde harmful gas monitoring and alarm device

Abstract

The invention discloses an indoor formaldehyde harmful gas monitoring and alarm device, which comprises a box body, wheels are symmetrically arranged at the bottom of the box body, an air inlet is opened on the top of the box body, and an air volume adjustment device is arranged at the air inlet port, and the air inlet is located below the box body. An induced draft fan is provided inside, a first drive motor is provided on one side of the air inlet, and a reinforced disturbance mechanism is connected to the output shaft of the first drive motor, and the reinforced disturbance mechanism includes a disturbance shaft. The invention adopts a strengthening disturbance mechanism to cooperate with the ultraviolet lamp, and the strengthening disturbance mechanism leads the formaldehyde airflow to the inverted V bar, which belongs to the place where the ultraviolet light gathers, thereby improving the formaldehyde removal effect. In the existing literature, a humidifying device is provided for ultraviolet light Catalytic oxidation provides water vapor, and the use of a humidifier to provide water vapor for catalytic oxidation alone reduces the formaldehyde treatment efficiency. The present invention divides the atomized water into two parts, and one part is used for preliminary mixing with formaldehyde to improve the dissolution effect of formaldehyde.

Description

technical field [0001] The invention relates to the technical field of harmful gas monitoring and alarming, in particular to an indoor formaldehyde harmful gas monitoring and alarming device. Background technique [0002] Formaldehyde has a strong irritating effect on the mucous membranes of the eyes, nose, and throat. The most common symptoms are eye irritation and headache. Severe cases can cause allergic dermatitis and asthma. Formaldehyde can react with proteins to form nitrogen methine compounds. The protein in the cell coagulates and denatures, thereby inhibiting cell function. In addition, formaldehyde can also react with ionic chloride in the air to generate dichloromethyl ether, which is a carcinogen. The material is adsorbed and enriched, and released again when the indoor temperature rises, aggravating the pollution effect. my country's "Indoor Air Quality Standards" stipulates that the limit of formaldehyde in the indoor air of Class II civil construction projec...

Problems solved by technology

[0003] Although the existing formaldehyde monitoring and alarm device can monitor the indoor formaldehyde concentration and achieve an alarm effect, it cannot process the formaldehyde after monitoring, thereby reducing the overall effect of the device. The alarm device is characterized in that the bottom of the cavity is provided with rollers, the side of the cavity is provided with an air inlet, a liquid crystal touch screen, and a voice device, the top of the cavity is provided with a door, and the door is provided with a handle , the air inlet is provided with a filter screen, and the filter screen is placed inside the cavity, and the cavity is also provided with a temperature sensor, a humidity sensor, a formaldehyde sensor, a benzene sensor, a control processing module, and a remote control device, a drive device, alarm device, the driving device is connected to the roller, the temperature sensor, humidity sensor, formaldehyde sensor, benzene sensor, LCD touch screen, voice device, driving device, wireless signal receiving device, alarm device are all connected to the control processing module, Although the device can realize monitoring and alarm, it cannot process formaldehyde, so the concentration of formaldehyde in the room cannot be reduced and improved.

[0004] Existing formaldehyde purification devices are relatively complicated in structure, and the efficiency of production and assembly is low. For example, the Chinese patent document publication number CN109028296A discloses an indoor formaldehyde purification device, which includes a filter box, an exhaust fan, a dust removal box, a formaldehyde purification box, a fluid pump and a bottom plate , the four corners of the bottom of the base plate are fixedly installed with universal wheels for easy movement, the top of the base plate is fixedly installed with a filter box, a dust removal box and a formaldehyde purification box in sequence from left to right, and a push handle is fixedly installed on the left outer wall of the base plate. Two sets of chutes are fixedly installed inside, and the honeycomb ceramic filter plate and activated carbon adsorption plate are respectively slidably installed on the chute, and the honeycomb ceramic filter plate is located directly below the activated carbon adsorption plate, and the exhaust fan is fixedly installed on the top of the filter box. Rectangular opening on the outer wall

Although the device can realize formaldehyde purification, the production and assembly are complicated, which is not conducive to large-scale production
