Efficient desulfurizing tower

Abstract

The invention relates to the technical field of environmental protection equipment, and in particular to an efficient desulfurizing tower. The efficient desulfurizing tower comprises a tower body, wherein a smoke outlet is formed in the top part of the tower body; the tower body is internally provided with multiple stages of spraying systems; multiple demisting and dedusting devices are arranged at the lower part of each stage of spraying system; the multiple demisting and dedusting devices are arranged in parallel or in series; the tower body is also internally provided with a row of smoke outlet demisting and dedusting devices; the smoke outlet demisting and dedusting devices are arranged near the smoke outlet; each of the demisting and dedusting devices and the smoke outlet demisting and dedusting devices comprises a shell, rotational flow plates are respectively arranged on the upper end and the bottom end of the shell, the rotational flow plates comprise rotational flow blades, and rotation directions of the rotational flow blades of the two rotational flow plates are opposite; the smoke outlet is connected with a smoke and dust purifier. The efficient desulfurizing tower disclosed by the invention is simple in structure and high in water mist removing rate.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a high-efficiency desulfurization tower. Background technique [0002] The desulfurization tower is an equipment for desulfurization treatment of industrial waste gas. It is an important equipment in chemical equipment. The desulfurization tower is a kind of desulfurization equipment with high desulfurization efficiency and low pressure loss, which can also remove dust. [0003] After years of improvement, the desulfurization tower has developed into various types of desulfurization towers such as spray type, Venturi type, swirl plate type, swirl column type, floating ball type, sieve plate type, and pneumatic emulsification type. Mature. [0004] The spray type desulfurization tower is one of the most widely used types of desulfurization towers. It uses alkaline liquid as a carrier to separate and treat harmful substances such as dust, sulfur dioxide,...

AI Technical Summary

Problems solved by technology

The liquid in the spray pipe is a circulating liquid, and there may be some solid impurity particles in it. When the liquid flows, it will scratch the inner wall of the pipe, thus affecting the service life of the pipe.

[0010] The tower body of the desulfurization tower is mostly made of glass flakes, and the glass flakes are prone to cracking and falling off after a long time, which will have a negative impact on the use of the desulfurization tower

In addition, there may be some solid impurity particles inside the desulfurization tower. When the liquid flows, it will scratch the inner wall of the desulfurization tower, thus affecting its service life.
