Novel high-temperature-resistant ventilating duct

Abstract

The invention provides a novel high-temperature-resistant ventilating duct. The novel high-temperature-resistant ventilating duct comprises a ventilating duct body, a high-temperature-resistant coating and a nano antibacterial material, wherein an upper flange plate is arranged on the ventilating duct body, connecting screw pins are arranged on the upper flange plate, the high-temperature-resistant coating and the nano antibacterial material are arranged on the inner wall of the ventilating duct body, a lower flange plate is arranged at the bottom of the ventilating duct body, and air outlets are formed in the two sides of the ventilating duct body. The novel high-temperature-resistant ventilating duct is reasonable in structure and simple in design; the duct wall strength is high, raw materials are saved, the ventilating duct cannot be easily blocked, the ventilating effect is good, and high temperature resistance is high; meanwhile, the novel high-temperature-resistant ventilating duct has the effects of antibacterial disinfection and air purification.

Description

technical field [0001] The invention belongs to the field of ventilation pipes, in particular to a novel high-temperature-resistant ventilation pipe made of composite materials. Background technique [0002] Ventilation ducts are an indispensable component in the ventilation system of modern buildings, and the materials of commonly used ventilation ducts are mostly metal or inorganic glass fiber reinforced plastics. Because the inorganic FRP ventilation pipe has the characteristics of strong corrosion resistance and non-combustibility, it is widely used. However, the inorganic FRP ventilation pipes currently produced generally do not have the functions of antibacterial, antivirus, and air purification, and after long-term use, a large number of bacteria, viruses, microorganisms, dust and other substances are deposited in the pipe wall, causing secondary air pollution. People's physical and mental health has brought great hidden dangers. In addition, raw materials are waste...

Problems solved by technology

However, the inorganic FRP ventilation pipes currently produced generally do not have the functions of antibacterial, antivirus, and air purification, and after long-term use, a large number of bacteria, viruses, microorganisms, dust and other substances are deposited in the pipe wall, causing secondary air pollution. People's physical and mental health have brought great hidden dangers

In addition, raw materials are wasted, the strength of the pipe wall is low, the ventilation pipe is easy to be blocked, and the ventilation is not smooth, and because it works in a humid environment, it is easy to absorb water and brine, warping and deforming, which greatly shortens the service life of the ventilation pipe
