Description

Novel energy-saving air purifier

Technical Field

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

Background

The types, principles and characteristics of the domestic air purifier are as follows:

1. Mechanical dust remover

The following dust removal modes are adopted:

a. A gravity dust remover; b. an inertial dust remover; c. a cyclone dust collector; d. a multi-pipe cyclone dust collector.

The four dust collectors exist in independent forms, the principle is the same, and the dust can naturally fall down in the high-speed rotation process by utilizing the self weight of dust, so that the dust collection purpose is achieved. However, they all have a common weakness in that they are not cleaned of particulate dust, not to mention that they are only suitable for use in mines, metallurgy and multiparticulate dust.

2. Wet dust remover

The following dust removal modes are adopted:

a. A spray scrubber; b. a venturi scrubber; c. self-excitation dust remover; d. a water film deduster;

The four dust collectors are in independent forms, and the principle of the dust collectors is that larger dust is filtered by utilizing air flow through a water curtain (with reverse direction and forward direction), so that the dust collectors cannot remove the fine dust, have large movement resistance and have a certain blocking effect on normal emission;

3. Filtering dust remover

The two most commonly used granular layer dust collectors and bag dust collectors adopting the form generally exist in independent forms, and the dust collector is characterized in that tiny dust cannot be filtered at the beginning, ventilation resistance is increased after a period of time (1 hour), normal emission is affected, and the fine dust is discharged reversely.

4. Electrostatic precipitator

The dust remover captures dust by utilizing the electric field principle, has good effect, but has high price and quite high operation cost, and is generally only suitable for purifying and removing dust of large enterprises and large pollution sources.

5. The dust-removing equipment for thermal power plant is a complete set of system equipment, including sulfur-removing and other harmful elements, and its principle is that it uses electrostatic dust-removing and spray-type dust-removing together, and then uses complex sulfur-removing process, and these equipment not only has large scale, but also has high cost, and its complete set of equipment can be up to several tens of millions of yuan.

All the dust removing devices described above are low in price, are mostly used singly, have certain limitations on effects, and are low in operating cost. And because of special Chinese national conditions, the difference between the north and south is large, the size enterprises are unevenly distributed, and the discharged pollution sources are also quite different. For these reasons, large purification devices (or importation devices) can be installed in large scale enterprises at a national level, and the prices of such devices are generally more than several hundred and tens of millions of yuan, which can be tolerated by large and medium-sized enterprises, and such devices are difficult to accept by small and medium-sized enterprises in general, and are particularly small enterprises, and are labor-intensive and even more difficult to accept by small enterprises. In fact, many pollutants in our country are discharged by some of these enterprises. Therefore, a small air purifier with small scale, low price, wide adaptability, obvious purifying effect and low operating cost is sought, and the small air purifier is the most effective way for controlling and treating the atmospheric pollution in the current stage of China.

The inventor has applied for patent publication number CN200710134903.9, publication day 2009.10.28 for the industrial small-scale air purifier of China, the inventor finds that the air purifier has not reached the expected effect in the long-term use in terms of the speed and efficiency of water-gas kneading, and the dust recycling and water resource recycling have low efficiency, the dust collection box and the water source in the water tank are frequently replaced, so the new application aims to solve the efficiency problem of the purifier, an air flow valve is arranged in an air guide pipe between a water-gas kneading device and a cyclone separation device, a high-efficiency mixing turbulent flow cavity of industrial waste gas and water mist is formed, and pressure difference is formed at two sides of the air flow valve, so that the flow speed of air flow in the air guide pipe is accelerated while the kneading efficiency is increased, the purifying efficiency is improved, the dust collection box is controlled to vibrate through a vibrator, the dust collection and solid particles filtered by the cyclone separator are effectively solved and the dust accumulation problem generated by sliding down to the dust collection box through the inner wall of a cylinder body, and the filter pressing efficiency of the dust collection box is better improved.
