Ventilation, dust removal and purification system

Abstract

The invention provides a ventilation, dust removal and purification system, and relates to the technical field of ventilation; the system comprises at least one circulating purification unit, at leastone fresh air unit and a heat exchange unit; the heat exchange unit is connected with the circulating purification unit and the fresh air unit, the circulating purification unit is arranged in an indoor space and provided with an air return pipe and an air outlet, and the air return pipe and the air outlet are both communicated with the indoor space and form indoor circulating purified airflow; the fresh air unit is arranged in the outdoor space and provided with a fresh air pipe and an exhaust pipe, and the fresh air pipe and the exhaust pipe both extend into the indoor space. Compared withthe prior art, the ventilation, dust removal and purification system provided by the invention is good in ventilation and dust removal effect, capable of purifying indoor air, low in system energy consumption, energy-saving and environment-friendly by separately arranging the fresh air pipe, the exhaust pipe and the air return pipe.

Description

technical field [0001] The invention relates to the technical field of ventilation, in particular to a ventilation dust removal and purification system. Background technique [0002] With the development of modern industrial technology, the construction of industrial plants in various industries is developing rapidly. The pollutants produced by industrial plants in the process of production are difficult to control. At the same time, there are strict requirements on temperature, humidity, pollutant concentration, noise, etc. At present All kinds of ventilation, dust removal, purification and air conditioning systems on the market have the characteristics of high energy consumption, especially for super large industrial plants, the energy consumption of the ventilation and dust removal, purification and air conditioning systems is quite large. [0003] At present, the airflow organization methods commonly used for ventilation and dust removal in industrial plants are as follo...

AI Technical Summary

Problems solved by technology

[0004] 1. Blow-suction ventilation: air is supplied on one side of the column of the factory building, and exhaust is arranged on the other side of the column. Through the large-span air supply and exhaust, it tries to capture pollutants. Its characteristic is that the air supply is in the form of a jet. Due to the large span of the factory building, the jet angle is generally controlled within 10°, and the height required for the return air outlet is quite large. At the same time, the air flow in the workshop is disordered, and the personnel working area has not been treated, the pollution problem has not been fundamentally solved, and the energy consumption is high.

[0005] 2. Ventilation of the whole air system: Air distributors are arranged on both sides of the factory building, and return and exhaust outlets are set on the top to transport air and suck air through long distances. The system fan adopts a double fan system. The system resistance is as high as 3000Pa or more, and the fan energy consumption is high.

On the other hand, the system adopts a combined dust removal and temperature control unit. When the temperature and humidity need to be controlled, the full air volume needs to go through the surface cooler or evaporator to use low-temperature refrigerant for deep dehumidification, and the overall energy consumption of the refrigeration system is high.
