Storied building fume centralized discharge monitoring system and method thereof

Abstract

The invention provides a central discharge monitoring system for building smoke and the discharge monitoring method. According to the each floor information and the air pressure value of present main pipe, the host computer of system can change the output frequency and voltage of inverter to realize the adjustment for fan speed so as to achieve the purpose of reasonable smoke exhaust and guarantee air quality of each user cell by stabilizing the air pressure value of main pipe. The system is provided with low equipment cost, small noise, good smoke exhaust performance, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the treatment of building flue gas, in particular to a building flue gas centralized emission monitoring system and an emission monitoring method thereof. Background technique [0002] With the development of society and the improvement of people's living standards, people put forward higher requirements for indoor living environment, and pay more attention to indoor air quality and environmental protection and health. However, the range hoods currently used generally have problems such as excessive noise and poor fume exhaust effect. Especially after the range hood has been used for a period of time, the noise increases, the fume exhaust effect becomes worse, and cleaning is more troublesome. What's more, the direct harm of oil fume to the surrounding environment and human body: [0003] (1) If the untreated lampblack is directly discharged outside, it will pollute the surrounding air and walls. Some volatile organic compound...

Problems solved by technology

[0003] (1) If the untreated oil fume is directly discharged outside, it will pollute the surrounding air and walls. Some volatile organic compounds in the oil fume will react photochemically with nitrogen dioxide in the atmosphere, causing serious air pollution.

[0004] (2) If the oily fume in the kitchen is not discharged in time and stays indoors, its strong permeability and viscosity will pollute and damage indoor objects, produce peculiar smell, and generate cockroaches, mosquitoes and other pests. What's more serious is that during the combustion of kitchen gas, nitrogen The generation of oxides will increase sharply, producing a large amount of harmful substances. After inhalation, it will cause lung diseases, asthma, bronchitis, emphysema and other diseases. In severe cases, it can lead to pulmonary fibrosis and damage chromosomes. The possibility of genetic inheritance with cells

[0005] (3) Noise pollution from range hoods

[0006] Since the beginning of 2000, newly-built commercial and residential buildings have basically been designed and installed with a centralized smoke exhaust system, that is, each household in the building is ventilated, exhausted, and kitchen fumes are discharged centrally through the internal pipelines of the building. The methods mainly include variable pressure and non-return. There are two types of valves, but these two methods are generally insufficient in exhausting smoke, especially in high-rise buildings. Some households cannot exhaust the smoke, and in some smoke exhaust systems, the smoke exhausting effect of all households’ kitchens cannot be achieved. Requirements, the problems of stringing smoke, falling smoke, poor smoke exhaust, water seepage and water leakage are difficult to solve

In order to effectively solve these problems, many engineers and researchers have made unremitting efforts, but most of them are focused on the structural design and improvement of check valves, flue, etc., or simply increasing the power of the smoking hood, and have not been able to fundamentally solve the problem. Solve the contradictions between limited improvement effect, energy waste and excessive noise
