Sludge incineration flue gas desulfurization system

Abstract

The invention belongs to the technical field of sludge treatment devices, and particularly relates to a sludge incineration flue gas desulfurization system which comprises a shell, a partition plate,an inner frame bin and a desulfurization liquid tank, the bottom of an inner cavity of the shell is fixedly connected with the partition plate through screws, and the top of the shell is fixedly connected with the inner frame bin through bolts. According to the sludge incineration flue gas desulfurization system, an inner container with the two ends connected with a flue gas outlet pipe and a fluegas inlet pipe is arranged in the shell, a supporting frame is matched to be connected with partition nets and a filter plate for use, impurities of flue gas can be filtered conveniently, inner frames containing combined frames are arranged at the bottom of the flue gas outlet pipe, and the combined frames are combined into a circular structure. A release nozzle is mounted at the bottom of each combined frame and can be uniformly and effectively matched with a desulfurization liquid tank to perform desulfurization liquid spraying, desulfurization treatment is conducted while the flue gas impurity is filtered, liquid level sensing and liquid shortage prompting can be performed in use of the desulfurization liquid tank, and the treatment stability of the system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sludge treatment devices, in particular to a sludge incineration flue gas desulfurization system. Background technique [0002] Sludge treatment refers to the process of reducing, stabilizing and harmless sludge such as concentration, conditioning, dehydration, stabilization, drying or incineration. The higher the degree of sewage treatment, the more sewage will be produced. The mud residue needs to be dealt with. Unless land treatment or sewage ponds are used to treat sewage, general sewage treatment plants must be equipped with sludge treatment facilities. For modern sewage treatment plants, the treatment and disposal of sludge has become the most complex and expensive part of the operation of the sewage treatment system. [0003] In the process of sludge treatment, sludge incineration is included, which is a process of sludge treatment. It uses an incinerator to heat and dry the dewatered sludge, an...

Problems solved by technology

[0006] The purpose of the present invention is to provide a flue gas desulfurization system for sludge incineration to solve the problem that in the process of the existing flue gas emission proposed in the above background technology, the flue gas contains certain solid particle impurities and lacks filtering methods. It is easy to cause internal blockage and agglomeration, and the filtration and desulfurization methods need to be carried out separately, and the desulfurization method is not uniform enough, which reduces the efficiency of sludge incineration flue gas desulfurization, and in the use of desulfurization liquid, there is a lack of effective liquid sensing And the way of prompting is prone to system shutdown during use, which reduces the stability of processing
