Purifying and treating device for domestic waste incineration tail gas

Abstract

The invention discloses a purifying and treating device for domestic waste incineration tail gas. The purifying and treating device comprises a tail gas purifying and treating device body, a large-particle solid material filtering device and a purifying reaction tank, wherein a first bottom plate is arranged on one side of the bottom of the tail gas purifying and treating device body. The invention is characterized in that a first high-efficiency filtering net and a second high-efficiency filtering net in the device can filter large-particle solid materials in the device before the tail gas purifying reaction by arranging the large-particle solid material filtering device on one side of the device; cooling treatment can be carried to the incineration tail gas and latter tail gas purification is facilitated by arranging a dust removing and cooling room; acid in the incineration tail gas in the purifying reaction tank can be fast removed by arranging an alkaline solution storing device and a fan which are connected with one side of the purifying reaction tank. The invention is high in integration degree, is capable of effectively cleaning pollutants in the tail gas, such as acid materials, waste solid particles, and the like, and enables the incineration tail gas achieving atmospheric emission standard.

Description

Technical field: [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a domestic waste incineration tail gas purification treatment device. Background technique: [0002] Garbage is what people leave behind in the process of life and production. The types of garbage include all items, so it is quite difficult to process. There are many types of garbage, difficult classification, high classification cost, and the smell produced during burning is also very difficult. There are not only the smell of plastic products, but also the smell of animal meat, etc. There are all kinds of smells. If the unpleasant smell is not controlled, it can even spread to several kilometers around. If it occurs during the incineration process, it will cause serious secondary pollution and cause disasters to humans. In addition, due to the complexity and particularity of the garbage components, a large amount of gaseous pollutants will inevitably b...

Problems solved by technology

[0003] However, when the current exhaust gas purification treatment device is in use, on the one hand, the integration of the equipment is not high, and it needs to occupy an additional area, which increases the investment cost of the equipment, and also leads to insufficient site adaptability of the equipment. During purification, there are also low efficiency and incomplete purification treatment operations, which lead to the fact that the working effect of the exhaust gas purification operation cannot effectively meet the needs of use, reduce the effect of waste incineration exhaust gas purification treatment, and make the garbage treatment still unsatisfactory. Pollution is still with us
