Problems solved by technology

[0012] (1) The current photocatalyst construction method uses the same photocatalyst material to spray, some have remarkable effects, and some have poor effects;
[0013] (2) After the construction of many photocatalysts is completed, there will be no effect after a few months. Even if the national standard is continuously tested, the removal rate of formaldehyde will drop from 80% to 65% under laboratory conditions for 7 days, and the removal rate of toluene will drop from 50% to 65%. 30%; according to the reasoning of energy conservation, the photocatalyst material is decreasing
[0014] (3) The photocatalyst film layer often falls off, producing more PM2.5, causing secondary pollution and endangering people's health

Embodiment 1

[0037] This technical verification uses a model LDR0009-0.7 electric heating steam generator (the heating device of this equipment is composed of two parts, the first part generates saturated steam, and the second part of the superheated steam heating tube is turned on when superheated steam is needed; therefore, the same equipment can be Generating saturated steam and superheated steam), the steam equipment is strictly operated in accordance with the operation; the temperature of superheated steam can be adjusted from 171 degrees to 410 degrees, and the pressure can be adjusted from 0 kg to 7 kg; the temperature of saturated steam can be adjusted from 100 degrees to 171 degree, pressure adjustable range from 0 kg to 7 kg. Standardize the operation to ensure safety.

[0038] The construction method of photocatalyst of the present invention comprises the steps:

[0039] (1) Cleaning of the construction surface

[0040] It takes about 1 hour to raise the temperature and pressu...

Embodiment 2

[0045] In the research and development process, once tried to adopt different cleaning methods, the results are as follows, the rest of the conditions are the same as in Example 1. The results are shown in the table below:

[0046]

Embodiment 3

[0048] In the process of research and development, different cleaning methods have been tried, and the remaining conditions are the same as in Example 1. The results are shown in the following table:

[0049]

[0050]

[0051] Conclusion: superheated steam has better cleaning effect, good static electricity removal effect, no material damage at all, no cleaning fluid at all, no residue in cleaning, no cleaning dead angle, thorough cleaning of floating dust, convenient construction, time-saving and efficient.

Abstract

The invention provides a construction method of a photocatalyst. The method comprises the following steps: (1) cleaning a construction surface with overhead steam; and (2) spraying a photocatalyst liquid to the cleaned construction surface in the step (1) with saturated steam. The construction method of the photocatalyst provided by the invention does not bright secondary pollution with overheatedsteam and saturated steam.

Description

field of invention [0001] The invention relates to a construction method of a photocatalyst. technical background [0002] With the gradual improvement of people's living standards, more and more attention is paid to health, and the requirements for living environment are getting higher and higher, and the air environment has become the most important aspect; especially the indoor air environment; indoor air environment governance is a relative indoor environmental pollution. In terms of indoor air environment management, it refers to the removal of indoor toxic and harmful gases, which mainly include formaldehyde, ammonia, benzene series, TVOC, etc., so that the pollution index reaches the national standard range. [0003] Photocatalyst air treatment has: [0004] (1) Comprehensiveness [0005] Photocatalyst is currently the safest and cleanest environmental purification material in the world. It is widely used in Europe, America, Japan, South Korea and other regions. Pho...
