Description

A water seal tank capable of effectively isolating working gas condensate and sealing liquid

Technical Field

The invention relates to the technical field of chemical equipment, and in particular to a water seal tank capable of effectively isolating working gas condensate from sealing liquid.

Background Art

In chemical technology, water seal tank refers to the equipment used to ensure the pressure of sealed gas and separate the sealed gas from gas and liquid. It is a safety facility that isolates volatile, toxic and harmful gases from the atmosphere. It can effectively reduce the pollution of gas volatilization to the environment and ensure the stable operation of the device.

Chemical equipment exists based on chemical technology and serves the chemical process flow. In the traditional chemical process flow, the water seal tank is mainly composed of a tank body, an outer cylinder, and an inner cylinder, which is designed to separate the working gas condensate from the sealing liquid, so that they do not contaminate each other and are collected and processed separately. However, in actual production, things often go against one's wishes. The reason is that the structure of the water seal tank itself cannot prevent the working gas condensate from entering the sealing liquid, contaminating the sealing liquid (see Figure 1), so that the originally clean sealing liquid must be treated before it can be discharged, which undoubtedly increases the operating cost.

Summary of the invention

In order to overcome the shortcomings of the prior art, the present invention provides a water seal groove that can effectively isolate the working gas condensate and the sealing liquid, ensuring that all the condensate enters the inner cylinder, effectively protecting the sealing liquid from contamination, thereby reducing operating costs and being more economical and environmentally friendly.

In order to achieve the above object, the present invention adopts the following technical solutions:

A water seal tank capable of effectively isolating working gas condensate from sealing liquid comprises a tank body, an inner tube, an outer tube, a cover plate and fins; the inner tube is connected to the bottom of the tank body and extends to the outside of the tank body, the end of which is a condensate outlet, and the top of the inner tube is in a funnel cone shape; a condensate inlet is arranged at the top of the outer tube, the outer tube is connected to the tank body through the cover plate, a fixed gap is left between the bottom of the outer tube and the bottom of the tank body, and a fixed gap is left between the inner tube and the outer tube; the fin is fixedly connected to the inner wall of the outer tube at the lower part of the condensate inlet, the fin is annular, the inner ring diameter is smaller than the conical upper edge of the inner tube, and an overlapping area is formed with the inner ring in the vertical direction.

The fin is in a circular ring shape.

The upper part of the tank body is provided with an overflow port, the lower part of the tank body is provided with a drain port, the side wall of the tank body is provided with a liquid level gauge, and the cover plate is provided with a water injection port.

A fixed gap of 5 to 500 mm is left between the inner cylinder and the outer cylinder.

The length of the overlapping area between the fin and the tapered upper edge of the inner tube is not less than 5 mm.

Compared with the prior art, the present invention has the following beneficial effects:

1) The present invention has a simple structure, compact and reasonable layout, and can fully meet the process requirements and reduce operation and running costs.

2) The inner ring of the fin of the present invention and the conical upper edge of the top of the inner tube form an overlapping area in the vertical direction, which can ensure that all the condensate enters the inner tube, thereby effectively protecting the sealing liquid from contamination, thereby reducing operating costs and being more economical and environmentally friendly.

DETAILED DESCRIPTION

The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[Example]

As shown in FIGS. 2 to 4 , a water seal tank capable of effectively isolating working gas condensate from sealing liquid comprises a tank body 1 , an inner tube 3 , an outer tube 4 , a cover plate 2 and fins 6 .

An overflow port 10 is arranged at the upper part of the side wall of the tank body 1 , a drain port 11 is arranged at the lower part of the side wall of the tank body 1 , and a liquid level meter 5 is arranged at the side wall of the tank body 1 .

The inner cylinder 3 is connected to the bottom surface of the tank body 1 and extends to the outside of the tank body 1. The end is a condensate outlet 8. The top of the inner cylinder 3 is in a funnel cone shape.

The top of the outer tube 4 is provided with a condensate inlet 7, the outer tube 4 is connected to the tank body 1 through the cover plate 2, the outer tube 4 is fixed to the cover plate 2, and the cover plate 2 is fixed to the top of the tank body 1. The cover plate 2 is provided with a water injection port 9.

A fixed gap is left between the bottom end of the outer cylinder 4 and the bottom surface of the tank body 1 , and a fixed gap of 5 to 500 mm is left between the inner cylinder 3 and the outer cylinder 4 .

The fin 6 is fixed to the inner wall of the outer cylinder 4 below the condensate inlet 7. The fin 6 is annular, and its inner ring diameter is smaller than the conical upper edge of the inner cylinder 3, and forms an overlapping area 12 in the vertical direction. The length of the overlapping area 12 is not less than 5 mm.

The working principle and working process of the present invention are as follows:

1) Before the water seal tank starts working, water is first injected into the tank body 1 through the water injection port 9 on the cover plate 2 until water flows out of the overflow port 10.

2) The condensate in the working gas pipeline is connected to the condensate inlet 7 through a pipeline, and the overflow port 10 and the condensate outlet 8 are connected to corresponding equipment through pipelines.

3) After the water seal tank starts working, due to the pressure difference between the working gas pressure and the atmospheric pressure, there is a height difference between the liquid levels of the inner tube 3 and the outer tube 4, and the heights of the two liquid levels fluctuate with the gas pressure fluctuation. At this time, the liquid level meter 5 can be used to determine whether it is necessary to continue to inject water into the tank body 1, with the principle that water flows out of the overflow port 10.

4) The condensate in the working gas continuously enters the inner tube 3 along the inner wall of the outer tube 4 through the fins and flows out from the condensate outlet 8 at the bottom of the inner tube 3.

5) During normal operation, the liquid level height in the tank body 1 can be observed through the liquid level meter 5, and water can be added to the tank body 1 from time to time; when the operation is stopped, the tank body 1 can be emptied through the drain port 11 at the bottom of the tank body 1.

The present invention has a simple structure, compact and reasonable layout, and can fully meet process requirements and reduce operation and running costs. The inner ring of the fin 6 of the present invention forms an overlapping area 12 with the conical upper edge of the top of the inner tube 3 in the vertical direction, which can ensure that all condensate enters the inner tube 3, thereby effectively ensuring that the sealing liquid is not contaminated, thereby reducing operating costs and being more economical and environmentally friendly.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
