Problems solved by technology

[0004] In view of the poor internal circulation effect existing in the existing reaction tower, due to the horizontal way of drawing out the airflow, the airflow outlet channel is easy to accumulate dust, and in order to avoid dust accumulation, the method of increasing the airflow extraction speed leads to further flow field organization chaos and internal circulation effect To solve a series of problems such as falling, the present invention designs a slope outlet reaction tower with a trapezoidal expansion structure at the top that can enhance internal circulation

specific Embodiment approach 1

[0008] Specific implementation mode one: (see figure 1 ) The slope outlet reaction tower that can enhance the internal circulation of this embodiment includes a tower body 1-4 and an air outlet channel 1-3, and the upper part of the tower body 1-4 also includes an expansion cylinder 1-2 and an expansion extension cylinder 1 -1, the expansion cylinder 1-2 is fixedly connected to the upper part of the tower body 1-4 with an inverted trapezoidal vertical section; the expansion extension cylinder 1-1 is fixedly connected to the upper part of the expansion cylinder 1-2 The vertical upward extension part with the same shape and area as the top of the expansion cylinder 1-2; the air outlet channel 1-3 is fixedly installed on the slope of the expansion cylinder 1-2, and the air outlet channel 1- 3 communicates with the expansion cylinder 1-2, and the center line of the air outlet channel 1-3 forms an angle β with the slope.

specific Embodiment approach 2

[0009] Specific implementation mode two: (see figure 1 ) The difference between this embodiment and the first embodiment is that the vertical section of the expansion cylinder 1-2 is an inverted right-angled trapezoid, which is more conducive to the stability of the tower structure.

specific Embodiment approach 3

[0010] Specific implementation mode three: (see figure 1 , figure 2 ) The difference between this embodiment and the second embodiment is that the cross-sections of the bottom and the top of the expansion cylinder 1-2 are rectangular. When this embodiment is adopted, figure 1 The A-A' profile corresponding to figure 2 .

Abstract

The present invention relates to an inclined plane outlet type reaction tower capable of enhancing internal circulation. Said reaction tower includes tower body, capacity-expanding cylinder body, capacity-expanding extended cylinder body and gas flow outlet channel. The capacity-expanding cylinder body is the portion which is fixedly connected on the upper portion of said tower body and whose vertical section is made into the form of inverted ladder; the capacity-expanding extended cylinder body is the portion which is fixedly connected with upper portion of capacity-expanding cylinder body and whose cross-section form and area are identical to that of top portion of the capacity-expanding cylinder body, and the gas flow outlet channel is fixedly mounted on the inclined panel of capacity-expanding cylinder body and communicated with said capacity-expanding cylinder body. Said invention can be extensively used in the environment protection and chemical field.

Description

technical field [0001] The invention relates to a flue gas pollution purification device in the fields of environmental protection and chemical industry, in particular to a reaction tower for flue gas pollution purification. Background technique [0002] The reaction tower equipment of circulating fluidization technology is widely used in chemical industry, energy, environmental protection and other fields. The semi-dry flue gas circulating fluidized bed desulfurization technology is mainly used. The key of this technology is to ensure that the gas flow in the tower is obtained The cycle effect of a certain rate is used to improve the utilization efficiency of the absorbent and obtain a high desulfurization rate. In the past, the technology mostly relied on adding external separation equipment to strengthen the circulation of solid particles in the tower. Enhancing the internal circulation of the reactor system can effectively improve the comprehensive performance of the re...
