Description

A new type of energy-saving air purifier

technical field

The invention relates to the technical field of industrial environmental protection equipment, in particular to a novel energy-saving air purifier.

Background technique

As mankind enters the 21st century, the rapid development of industrialization and the disorderly discharge of various pollutants have seriously affected the global environment, and some areas have reached the point where it is difficult to survive. Although the country has repeatedly issued orders to control emissions , Renovate the environment. The types, principles and characteristics of commonly used air purifiers in China are as follows:

1. Mechanical dust collector

There are several types of dust removal in this form:

a. Gravity dust collector; b. Inertial dust collector; c. Cyclone dust collector; d. Multi-tube cyclone dust collector.

The above four dust collectors all exist in an independent form, and their principles are the same, using the weight of the dust itself to fall naturally during the high-speed rotation to achieve the purpose of dust removal. But they all have a common weakness, that is, the particulate dust cannot be removed, not to mention the smoke dust, and they can only be used in mines, metallurgy and multi-particle dust.

2. Wet dust collector

There are several types of dust removal in this form:

a. Spray scrubber; b. Venturi dust collector; c. Self-excited dust collector; d. Water film dust collector;

The above four dust collectors also exist in an independent form, and their principle is to use the airflow to pass through the water curtain (with reverse and forward directions) to filter the larger dust, and it is also impossible to remove the fine dust, and the movement resistance is large. , has a certain hindering effect on normal discharge;

3. Filter dust collector

In this form, the most commonly used ones are granular layer dust collector and bag dust collector, which generally exist in an independent form. Its characteristic is that the tiny dust cannot be filtered at the beginning, and it can be ventilated after a period of time (1 hour). The increased resistance will affect the normal discharge, and the particulate dust will be discharged backwards.

4. Electrostatic precipitator

This kind of dust collector uses the principle of electric field to capture dust. Although the effect is good, it is expensive and the operating cost is also quite high. Generally, it is only suitable for the purification and dust removal of large enterprises and large pollution sources.

5. The dust removal of the thermal power plant uses a complete set of system equipment, including the removal of sulfur and other harmful elements. Huge and expensive, the whole set of equipment will cost tens of millions of yuan.

All the dust removal equipment introduced above are not only not cheap, but most of them are single-use, the effect is limited to a certain extent, and the operating cost is not low. Moreover, due to China's special national conditions, there is a large gap between the north and the south, and the distribution of large and small enterprises is uneven, and the pollution sources emitted are also very different. In view of these reasons, large state-level enterprises can install large-scale purification equipment (or imported equipment), and the price of these equipment is generally more than tens of millions of yuan, which may be affordable for large and medium-sized enterprises, but for general small and medium-sized For enterprises, it is difficult to accept such equipment, especially small enterprises, and labor-intensive small enterprises, it is even more difficult to accept such equipment. In fact, many pollutants in our country are discharged by these enterprises. Therefore, seeking a small-scale air purifier with small scale, low price, wide adaptability, obvious purification effect and low operating cost is the most effective way to control and treat air pollution in China at this stage.

The applicant once applied for a small industrial air purifier with the patent publication number of CN200710134903.9 and the publication date of 2009.10.28. The applicant found that the air purifier used to knead water and air in terms of speed and efficiency In the process of long-term use, the expected effect has not been achieved, and the efficiency of dust recovery and water resource recovery is low, and the water source in the dust collection box and water tank is frequently replaced. Therefore, the new application aims to solve the efficiency problem of the purifier. An air flow valve is set in the air guide pipe between the air kneading device and the cyclone separation device, forming an efficient mixing turbulence chamber for industrial waste gas and water mist, and forming a pressure difference on both sides of the air flow valve, while increasing the kneading efficiency Speed up the flow rate of the airflow in the air guide pipe, improve the purification efficiency, control the vibration of the dust box through the vibrator, effectively solve the problem that the dust and solid particles filtered by the cyclone separator slide down to the dust box through the inner wall of the cylinder The dust accumulation problem, coupled with the pressure filtration of the filter plate, better improves the dust collection and filtration efficiency of the dust collection box.
