Abstract

The utility model provides a guniting pipe of a liquid column tower, which has convenient processing and can save pipes. The realization method is that the guniting pipe comprises a pipe body, wherein a nozzle is arranged at the spraying segment of the pipe body, and the diameter of the spraying segment of the pipe body is gradually decreased along the flow direction of liquid; further, the spraying segment of the pipe body is formed by splicing reducer pipes. The guniting pipe of the liquid column tower is manufactured in a way that the diameter of the spraying segment of the pipe body is gradually decreased along the flow direction of the liquid, therefore, the processing is convenient, and the pipes are not wasted; further, in the technical scheme, the pipe body is formed by splicing the reducer pipes, therefore, the processing is more convenient.

Description

Liquid column spray pipe

technical field

The utility model relates to the technical field of environmental protection engineering, in particular to a spray grouting pipe of a liquid column tower.

Background technique

The liquid column column is a wet desulfurization device especially suitable for high-sulfur coal, which has the advantages of simple structure, low investment and convenient maintenance. The slurry injection height and slurry flow distribution uniformity of the liquid column column have a great influence on the desulfurization characteristics of the liquid column column, and the form of the spray tube will directly affect the slurry injection height and flow rate of each nozzle of the liquid column column.

In order to ensure the flow uniformity of each nozzle 2 as shown in Fig. 1, the current common practice is to arrange a diversion baffle 3 that descends from the top to the inlet at the top of the spray pipe body 1 to increase the pressure at the top of the spray pipe , by adjusting the length and inclination of the guide baffle 3 to ensure the slurry injection height and flow distribution uniformity.

The existing spray pipes have the problems of inconvenient manufacture and processing, waste of pipe materials and the like.

Utility model content

In view of this, in order to solve the above problems, the utility model provides a liquid column tower spray pipe, which is easy to process and can save pipe materials.

The purpose of the utility model is achieved as follows: it includes a pipe body, the spray section of the pipe body is provided with a nozzle, and the diameter of the spray section of the pipe body gradually becomes smaller along the liquid flow direction.

Further, the injection section of the pipe body is spliced by reducing pipes.

The spraying pipe of the liquid column tower of the utility model is made by adopting the method that the diameter of the spraying section of the pipe body gradually decreases along the liquid flow direction, which is convenient for processing and does not waste pipe materials; into, processing is more convenient.

Other advantages, objectives, and features of the present utility model will be set forth in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the investigation and research below, or Can get teaching from the practice of the present utility model. The objectives and other advantages of the utility model can be realized and obtained by the structure particularly pointed out in the following description, claims, and accompanying drawings.

Description of drawings

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings:

Fig. 1 shows the structural representation of the existing liquid column tower spray pipe;

Fig. 2 shows a schematic structural diagram of the spraying pipe of the liquid column tower of the present invention.

Detailed ways

Preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

Referring to Fig. 2, the spraying pipe of the liquid column tower in this embodiment is provided with a nozzle 2 in the spraying section of the pipe body 1, and the spraying section is formed by splicing L1, L2, L3 and L4 section reducing pipes, for different For liquid column tower spray pipe, increase or decrease the number of reducing pipes and the length, diameter and diameter reducing ratio of each section according to the actual situation, so as to ensure the uniformity of the spray flow and spray height of each nozzle.

The above descriptions are only preferred embodiments of the utility model, and are not intended to limit the utility model. Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. In this way, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and equivalent technologies thereof, the utility model is also intended to include these modifications and variations.

Claims (2)

1. the liquid column tower shotcrete pipe comprises body, and the jet segment of body is provided with nozzle, it is characterized in that: the jet segment diameter of described body diminishes gradually along flow direction.

2. liquid column tower shotcrete pipe as claimed in claim 1 is characterized in that: the jet segment of described body is spliced by reducer pipe.
