example 1

[0025] Example 1: Nano TiO 2 Preparation of xerogel:

[0026] Get 2000ml butyl phthalate and dissolve it in the ethanol solvent, drop it in the nitric acid solution under stirring with a magnetic stirrer, stir after dropping to get TiO 2 Prebody. Dissolve it in the gel solution, stir and cool it to obtain a block, and anneal it at 650°C for 1 hour to obtain TiO with a nanoporous structure. 2 Xerogel composite photocatalytic material.

example 2

[0027] Example 2: Fe 3+ Compound doped nano TiO 2 Preparation of xerogel:

[0028] Get 2000ml of butyl phthalate and dissolve it in ethanol solvent, add an appropriate amount of ferric oxide therein, drop it into the nitric acid solution under stirring with a magnetic stirrer, stir after dropping to obtain TiO 2Prebody. Dissolve it in the gel solution, stir and cool it to obtain a block, and anneal it at 650°C for 1 hour to obtain Fe doped with nanoporous structure. 3+ TiO 2 Xerogel composite photocatalytic material.

example 3

[0029] Example 3: Rhodamine doped nano-TiO 2 Preparation of xerogel:

[0030] Get 2000ml of butyl phthalate and dissolve it in ethanol solvent, add an appropriate amount of rhodamine therein, drop it in the nitric acid solution under stirring with a magnetic stirrer, stir after dropping to obtain TiO 2 Prebody. Dissolve it in the gel solution, stir and cool it sufficiently to obtain a block, and anneal it at 650°C for 1 hour to obtain rhodamine-doped TiO with a nanoporous structure. 2 Xerogel composite photocatalytic material.

Abstract

The invention discloses a combined type indoor air purifier, which comprises a shell (1), a fan (2) and a purification system inside the shell (1) and is characterized in that the purification system comprises a photocatalytic purification chamber (3) and a physical adsorption pool (4) which are formed by dividing the shell (1) by a clapboard (8), the clapboard (8) is provided with a through hole which is connected with an absorption tube (9), and the absorption tube (9) is communicated to the bottom end of the physical adsorption pool (4) directly; the photocatalytic purification chamber (3) is internally provided with at least five pieces of nano-titania xerogel or / and doped nano-titania xerogel (5) parallel to a cross section of the shell (1) and an ultraviolet light tube (6), the ultraviolet light tube (6) penetrates through a hole in each xerogel (5), and each piece of xerogel (5) is densely provided with air holes; and the physical adsorption pool (4) is internally provided with a water absorption liquid (7) containing a chemical catcher with the mass percentage concentration being 0.001-20%. The combined type indoor air purifier can be used for completely removing formaldehyde, benzene, toluene and other pollutants in the air and killing bacteria and viruses, and is suitable for purifying air in a room and in a vehicle.

Description

1. Technical field [0001] The invention relates to an indoor air purifier, in particular to a composite indoor air purifier. 2. Background technology [0002] With the development of social economy and the continuous improvement of people's living standards, interior decoration has become an important means for people to improve their living conditions and quality of life, but it has also become an important source of indoor air pollution, which has aggravated the deterioration of indoor air quality. deterioration. Experts at home and abroad have conducted a lot of research on indoor air pollution, and hundreds of toxic and harmful substances have been detected. According to relevant reports, at present, indoor air pollutants in decoration projects in my country mainly include formaldehyde, benzene and other TVOCs (that is, the sum of volatile organic compounds), which can cause more than 30 diseases in the human body, and even cancer. The harm of indoor pollutants has reac...
