Description

Vertical spray washing tower for improving waste gas treatment efficiency in cyclone diffusion mode Technical Field The invention relates to the technical field of chemical waste gas treatment equipment, in particular to a vertical spray washing tower for improving waste gas treatment efficiency in a cyclone diffusion mode. Background The spray scrubber is one of the most commonly used waste gas treatment equipment in the chemical industry, and the core principle is that the absorption, neutralization or sedimentation of harmful components in waste gas is realized through gas-liquid contact (water or chemical agent mixed liquid is usually adopted), and the method specifically comprises the steps of acid gas removal, alkaline gas removal, particulate matter removal, partial Volatile Organic Compounds (VOCs) removal and malodorous gas treatment, so that the environmental protection emission standard or the process requirement is met. The traditional spray washing tower generally comprises a vertical tower body, an air inlet section, an air outlet section, a spray mechanism, a packing layer and a circulating liquid system, wherein waste gas enters the tower body from the air inlet section and fully contacts with liquid sprayed from top to bottom in the packing layer, and after harmful components are absorbed by the liquid, purified gas is discharged from the air outlet section. However, the existing spray scrubber generally has the problem of low waste gas treatment efficiency, and the problems are specifically expressed in the following two aspects: The inlet direction and distribution of the waste gas are unreasonable, namely the pipe orifice of the traditional inlet section extends into the tower body normally horizontally or approximately horizontally, the waste gas flows upwards rapidly along a straight line after entering, so that the residence time of the waste gas in the tower is too short, the contact reaction time with the spray liquid is insufficient, and the absorption or neutralization process is difficult to complete; The lack of an exhaust gas diffusion structure is that the existing air inlet section is not provided with a special diffusion device, and after the exhaust gas enters the tower body in a beam shape or a ball shape, the exhaust gas cannot be rapidly diffused and is fully mixed with spray liquid, so that the problem of insufficient reaction is further aggravated, and particularly when the high-concentration or large-air-volume exhaust gas is treated, the treatment effect is obviously reduced. Disclosure of Invention The invention aims to solve the technical problem of providing a vertical spray washing tower which improves the waste gas treatment efficiency in a cyclone diffusion mode, and by optimizing the air inlet direction of an air inlet section and adding a cyclone diffusion component, waste gas is uniformly dispersed to the lower part of a tower body in a cyclone mode, so that the residence time is prolonged, the contact effect with spray liquid is enhanced, the waste gas treatment efficiency is obviously improved, and the problem that the existing spray washing tower generally has low waste gas treatment efficiency is solved. In order to achieve the above purpose, the present invention provides the following technical solutions: A vertical spray washing tower for improving waste gas treatment efficiency in a cyclone diffusion mode comprises a vertically arranged tower body structure and a circulating liquid system arranged beside the tower body structure, wherein a spray mechanism and a packing layer are arranged in the tower body structure, an air inlet section and an air outlet section which are communicated with the inside of the tower body structure are sequentially arranged on the side wall and the top end of the tower body structure, the core improvement is that the air inlet section which extends into the tower body structure obliquely downwards, a cyclone diffusion assembly is arranged at a pipe orifice of the air inlet section, and when waste gas of the air inlet section passes through the cyclone diffusion assembly, the waste gas is uniformly diffused to the lower part in the tower body structure in a cyclone mode. Through adopting above-mentioned scheme, this spray scrubber is through setting up and cooperation whirl diffusion subassembly downwards with the section slope of admitting air, makes waste gas get into the tower body back along spiral route downwardly moving, has prolonged the initial dwell time of waste gas in the tower on the one hand, and on the other hand will concentrate the waste gas homogeneous dispersion that gets into to tower body lower part space through the whirl effect, avoids local air pocket to gather, for follow-up and the abundant contact creation condition of spray to show promotion overall treatment efficiency.
