Problems solved by technology

[0002] In the current environment, air pollution is very serious. Air pollution refers to the entry of certain substances into the atmosphere due to human activities or natural processes, presenting sufficient concentrations for sufficient time, and thus endangering human comfort, health and welfare. Or environmental phenomena, in other words, as long as the quantity, nature and time of existence of a certain substance are sufficient to affect human beings or other creatures and property, we can call it air pollutants, and the phenomenon caused by its existence, It is air pollution, and the air quality in the building will be better, but it is impossible to not ventilate for a long time, and the general ventilation needs to be built with ventilation pipes on the wall. In order to improve construction efficiency and save costs, it is currently commonly used Prefabricated building ventilation flue, the current ventilation flue generally uses a prefabricated rectangular cylindrical ventilation duct; according to the needs of use, there are temporarily air holes on the wall of the rectangular tube; inside the air hole Simply place a fan to complete the ventilation work inside the building. However, the current external environment is more polluted. This structure cannot purify the outside air. Inhalation into the room will cause the indoor air quality to decline. Long-term adsorption of this pollution is more Severe air can cause people to be infected with diseases, etc. At the same time, when ventilating, the heat in the room will be dissipated, which will cause the problem of a drop in room temperature. In the cold winter, people may be infected with wind chills and other problems.

Embodiment 1

[0027] see Figure 1-4, an embodiment provided by the present invention: a new type of fresh air fan for building ventilation, including a housing 1, a fixing groove 3, a fixing block 5, a heat exchanger 7 and an air inlet pipe 9, and the inside of the housing 1 is stuck in the shell The fixed block 5 inside the body 1, the fixed block 5 can install and fix multiple devices, prevent the devices installed inside the device from falling off, and enhance the stability of the device. The connected air outlet pipe 6, through the air outlet pipe 6, the gas can be confined inside the pipe, preventing the mixing of indoor air and outdoor air, and ensuring the cleanliness of the indoor air. One side of the air outlet pipe 6 passes through its own The dust-proof net 601 is plastically installed, and the dust-proof net 601 can prevent external large-scale pollutants from entering the interior of the device, thus affecting the operation of the device. The side of the fixed block 5 away fr...

Embodiment 2

[0033] The activated carbon core 302 is TiO2 with activated carbon fiber as the carrier. 2 Photocatalytic materials, the production steps are as follows:

[0034] S1, nano-Ti0 2 For the preparation of photocatalyst, dissolve 8.5g tetrabutyl titanate in 10ml absolute ethanol, stir and place it for 6-8 minutes to obtain a uniform and transparent solution; then take deionized water and adjust the pH value to 8.0 with a small amount of acid or ammonia water , the latter was slowly added dropwise to the organic solution of butyl titanate under the action of magnetic stirring, R value = 50, and a uniform and transparent sol solution was obtained at this time; adding Fe 3+ , with a concentration of 3.Swt%, aged at room temperature for 12 hours after colloidal gelation, then dried at a temperature of 110±10°C for 1 hour, then baked at a temperature of about 80°C for 2 hours, and finally placed in a horse Roasting at 650°C for 2 hours in a Furnace, and grinding the prepared catalyst ...

Embodiment 3

[0041] Described primary effect HEPA filter element 303 and high-efficiency HEPA filter element 301 adopt micron wood fiber filter element, and manufacturing process is as follows, and the processing equipment that adopts is numerical control type micron cutting machine,

[0042] The process includes: the raw material is fir fir, with a moisture content of 45%-65%; fiber cutting, the average thickness of the fiber can reach 50um; kneading silk, after kneading, its width is between 2-4mm, and the length is between 20-40mm; Fiber metering; mold making; mold unloading; inspection; molding to produce a micron wood fiber filter element, namely the primary effect HEPA filter element 303;

[0043] The pre-production process of the high-efficiency HEPA filter element 301 is the same as that of the primary-efficiency HEPA filter element 303. After the micron wood fiber filter element is formed, it is placed in a drying oven to dry for 2 hours to make it carbonized.

Abstract

The invention discloses a novel fresh air ventilator for building ventilation. The novel fresh air ventilator comprises a shell, a fixing groove, a fixing block, a heat exchanger and an air inlet pipe, the fixing block is installed in the shell, two sides above the fixing block are provided with exhaust structures, an installation shell is installed in each exhaust structure, a fan is installed ineach installation shell, turbine blades are arranged on the outer side of each fan, a protection shell is installed on the front side of each installation shell, the periphery of the heat exchanger is connected with an air duct, an air inlet and the exhaust structures through a hose, a housing is installed on the front side of the shell, and a protective plate is arranged on the front side of thehousing. By the arrangement of the heat exchanger, indoor heat is recovered maximumly during ventilation, the problem about falling room temperature in winter is solved, and indoor staff are prevented form catching cold; the novel fresh air ventilator can be disassembly by the arrangement of the protective plate, regular cleaning of a filter element is facilitated, and normal operation of the novel fresh air ventilation is guaranteed.
