In the traditional chemical process flow, the water seal tank mainly comprises a tank body, an outer cylinder and an inner cylinder, and aims to separate working gas condensate from sealing liquid, so that the working gas condensate and the sealing liquid are not polluted by each other and are collected and treated respectively. But in actual production, the situation is often reluctant. The reason is that the structure of the water seal tank cannot avoid the working gas condensate from entering the sealing liquid to pollute the sealing liquid (see attached figure 1), so that the originally clean sealing liquid can be discharged after being treated, and the operation cost is increased undoubtedly.

[ examples ] A method for producing a compound

As shown in fig. 2 to 4, the water seal tank capable of effectively isolating working gas condensate from sealing liquid comprises a tank body 1, an inner cylinder 3, an outer cylinder 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 vent 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 with the bottom surface of the tank body 1 and extends to the outside of the tank body 1, the tail end of the tank body is provided with a condensate outlet 8, and the top of the inner cylinder 3 is in a funnel cone shape.

The top of the outer barrel 4 is provided with a condensate inlet 7, the outer barrel 4 is connected with the tank body 1 through the cover plate 2, the outer barrel 4 is fixedly connected onto the cover plate 2, and the cover plate 2 is fixedly connected onto the top of the tank body 1. The cover plate 2 is provided with a water filling port 9.

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

The fin 6 is fixedly connected to the inner wall of the outer cylinder 4 at the lower part of the condensate inlet 7, the fin 6 is annular, the diameter of the inner ring of the fin 6 is smaller than that of the conical upper edge of the inner cylinder 3, an overlapping area 12 is formed in the vertical direction of the fin and the conical upper edge, and the length of the overlapping area 12 is not smaller than 5 mm.

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

1) before the water seal tank starts to work, water is 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 with a condensate inlet 7 through a pipeline, and an overflow port 10 and a condensate outlet 8 are connected with corresponding equipment through pipelines.

3) After the water seal tank starts to work, because the pressure difference exists between the working gas pressure and the atmospheric pressure, the height difference appears on the liquid level between the inner cylinder 3 and the outer cylinder 4, and the height of the liquid level at the two positions changes along with the fluctuation of the gas pressure. At this time, the liquid level meter 5 can be used for judging whether water needs to be continuously injected into the tank body 1 or not, and the principle that water flows out from the overflow port 10 is taken as a principle.

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

5) When the device is in normal operation, the liquid level height in the tank body 1 can be observed through the liquid level meter 5, and water is supplied to the tank body 1 irregularly; when the work is stopped, the tank body 1 can be emptied through the emptying port 11 at the bottom of the tank body 1.

The invention has simple structure and compact and reasonable arrangement, can completely meet the process requirement and reduce the operation and running cost. According to the invention, the inner ring of the fin 6 and the conical upper edge of the top of the inner cylinder 3 form an overlapping area 12 in the vertical direction, so that all condensate can be ensured to enter the inner cylinder 3, and therefore, the sealing liquid can be effectively prevented from being polluted, the operation cost is reduced, and the method is more economical and environment-friendly.
