Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization equipment, in particular to a biomass boiler flue gas desulfurization chimney integrated tower. Background Art

[0002] With the increasing attention paid to environmental protection, the flue gas emission problem of biomass boilers has received widespread attention. The desulfurization tower can remove harmful gases in the flue gas to make the flue gas emissions meet national standards. The desulfurization tower is widely used in the desulfurization and dust removal industry of coal-fired boilers. It can usually remove sulfur dioxide and purify tail gas by wet dust removal, wet desulfurization, or integrated dust removal and desulfurization. Wet desulfurization usually uses water spraying to make water contact with sulfur dioxide, and then the water adsorbs sulfur dioxide, thereby purifying the tail gas. However, in the use of the existing boiler desulfurization chimney integrated tower, the positions of the nozzles or spray holes used for spraying are mostly fixed, resulting in a relatively fixed and limited spraying range, and the water mist cannot be evenly distributed in the desulfurization area, and the desulfurization effect of the tail gas in the mist coverage area is poor.

The boiler desulfurization chimney integrated tower drives the atomizing nozzle to rotate and reciprocate up and down by starting the driving motor, so that the sprayed water mist can fully and evenly cover the area between the second baffle and the third baffle, so that the tail gas in the area between the second baffle and the third baffle can contact with the water mist, so as to improve the effect of tail gas desulfurization, and finally achieve the purpose of good desulfurization effect.

In the long run, the dust net is very likely to be blocked, which will have an adverse effect on the normal passage of the exhaust gas. It can be understood that the above scheme can also be used to improve the reliability of equipment operation.

[0021] In this embodiment, the tower body 102 is a prior art, and a chimney is arranged on the top of the tower body 102, and an atomizing nozzle, a water delivery component and a driving mechanism (not shown in the attached drawings) are arranged inside. The water delivery component can provide water delivery, and the water is delivered to the atomizing nozzle through the water delivery component, and then the atomizing nozzle atomizes and sprays the water, and the sulfur dioxide in the exhaust gas is adsorbed by the water mist. The driving mechanism can drive the atomizing nozzle to rotate, and through the rotation of the atomizing nozzle, the water mist is sprayed to the surroundings to increase the coverage of the water mist, thereby improving the effect of exhaust gas desulfurization. The dustproof net body 10 3 is fixedly connected to the inner wall of the tower body 102 and is located at the lower part of the tower body 102. The exhaust gas enters the tower body 102 from the smoke inlet pipe. When the exhaust gas passes through the dustproof net body 103, dust and other particles are filtered. The cleaning component is installed inside the tower body 102, so that the dustproof net body 103 can be cleaned, which solves the problem that although the prior art can effectively filter dust and other particles through the setting of the dustproof net, it is not equipped with a corresponding cleaning mechanism.

There are two rotating arms 107, which are symmetrically arranged on both sides of the connecting sleeve 106. There are two brush plates 111, which are respectively installed on the two rotating arms 107 through two groups of elastic components. The brush plates 111 are provided with bristles, which can clean the dustproof net body 103. The elastic component is used to provide elastic support for the brush plate 111 to avoid the brush plate 111 from having a gap with the dustproof net body 103 after being worn, thereby affecting the cleaning effect. The driving component is used to drive the shaft 105 to rotate. The shaft 105 is driven to rotate by the driving component, thereby driving the brush plate 111 to sweep the dustproof net body 103 to clean the dustproof net body 103. This solves the problem that although the prior art can effectively filter dust particles and the like through the setting of the dustproof net, it is not equipped with a corresponding cleaning mechanism.
