Purification and dust removal device

Abstract

A purification and dust removal device, which is composed of three purification boxes of dust removal, precision, and dehumidification in sequence. Each box has an isolation tube. The isolation tube in the dust removal and purification box communicates with the air inlet, and there is a spray dust removal device in the tube. The device draws water in the dehumidification and purification box through the water pump; the isolation pipe of the precision purification box communicates with the air outlet, connects the pumping motor and then connects the isolation pipe of the dehumidification and purification box; this device also has a purification liquid feeding device, an observation box, and a sewage pipe and other ancillary equipment; the present invention first realizes preliminary dust removal by spraying, and then through the high-speed airflow generated by the air pumping motor, the surge formed when passing through the isolation tube and the liquid surface of the purification liquid increases the contact between the exhaust gas and the purification liquid, thereby It produces a significant dust removal and purification effect, and finally removes the water molecules in the tail gas through the dehumidification and purification box to obtain dry and safe exhaust gas. It has the advantages of simple structure, reliable operation, high dust removal and purification efficiency, and transparent exhaust gas without white smoke.

Description

Technical field [0001] The invention relates to a purification and dust removal device for dust removal, decontamination and purification treatment of waste gas, in particular to a purification and dust removal device for dust removal and purification by adopting the surge principle. Background technique [0002] With the continuous strengthening of the society's awareness of environmental protection, all kinds of waste gas such as chemical plants, steel plants, pharmaceutical factories, coking plants, thermal power plants, oil refineries, waste incinerators, industrial boilers, textile industry setting machine equipment, etc. , pre-purification treatment, and then discharged into the natural environment, has been a consensus in production, and it is also a requirement of national laws. Therefore, there is a considerable demand for purification and dust removal devices for dust removal, decontamination and purification treatment of exhaust gas. The existing purification and...

AI Technical Summary

Problems solved by technology

First of all, the water mist dedusting water tank takes up a lot of space and can only treat dirt particles above PM50, while the first surge purification water tank can handle about 80% of larger particles, so the water mist dedusting The effect is not good, and it is useless and wasteful; secondly, multiple purification tanks are connected in series for a long distance, the front water tank cannot obtain the ideal negative pressure effect, and the surge state does not obviously affect the effect of the front purification tank; in addition, the original purification equipment is aimed at the exhaust gas of waste incineration Treatment, unable to put chemical neutralizers and provide other industrial waste gas such as sulfur neutralization treatment of sulfur-containing waste gas

In addition, although the dust removal and purification effect of the original technology is obvious, the clean exhaust gas discharged into the air does not contain harmful substances and dirt particles, which meets the emission standards, but because the purification box works in a state of saturated steam, the exhaust gas is full of water vapor and forms white smoke. gas, making bystanders mistakenly think that it contains harmful gases, affecting the overall use of the equipment and the evaluation of bystanders, and also making the original technology unable to be applied to some exhaust gas recycling equipment
