Description

A Y-shaped water-sealed tank

technical field

The utility model belongs to the technical field of a low-pressure-drop gas-phase medium water-sealed tank in the petrochemical industry, and mainly relates to a Y-shaped water-sealed tank.

Background technique

At present, when the gas phase medium is transported with large flow rate and large flow channel (pipeline diameter > 2m) in the flue gas pipeline system of the petrochemical industry, the following pipeline cutting techniques are usually adopted:

1. Large cut-off valve. However, large-scale globe valves have technical problems such as design and manufacture difficulties, high-temperature deformation, jamming and difficult operation. Related products have not yet appeared in China and need to be imported, so the price is expensive;

2. Large regulating butterfly valve. Large-diameter butterfly valves have problems such as expensive price, poor sealing, and easy deformation and leakage when heated, so they are only used in occasions where a small amount of gaseous medium is allowed to leak or as an emergency cut-off; Supplemented by other sealed cut-off measures;

3. Traditional water-sealed tanks. Water-sealed tanks are currently the most commonly used means of cutting, and have the advantages of easy manufacture, low cost, good sealing, and no leakage. When transporting through it, processes such as expansion deceleration, capacity expansion, 180° turning, and shrinkage acceleration have been carried out, resulting in a large pressure loss when the gas phase medium normally passes through the water-sealed tank (the calculation and actual measurement results approximately increase the pressure drop by 5-8kPa), thus It directly affects the transmission power input or energy recovery output of the gaseous medium, increasing energy consumption. It is of practical significance to develop a new type of water-sealed tank for this reason.

Contents of the invention

The purpose of this utility model and its technical solution are to adopt the following technical solutions to achieve. A Y-shaped water-sealed tank proposed according to the utility model includes a cylindrical tank body 2, a communication port, a communication pipe, an overflow port 4, a water inlet and outlet 5 and a guide vane 6. The top of the tank body 2; the connecting pipe is a streamlined elbow installed on one side of the cylindrical tank body 2; the connection between the cylindrical tank body 2 and the connecting pipe is provided with a plurality of guide vanes 6; The water inlet and outlet 5 are arranged at the bottom of the cylindrical tank body 2, and the overflow outlet 4 is arranged above the mouth of the communicating pipe. The flue gas enters the cylindrical tank body 2 from the communicating pipe (or communicating port), and flows out from the communicating port (or communicating pipe). Combined with this "U" shape, it looks like a "Y" shape, so the water-sealed tank is called a Y-shaped water-sealed tank.

The purpose of the utility model and its technical problem solving also adopt the following technical measures to further realize.

Detailed ways

In order to further explain the technical means and effects of the utility model to achieve the intended purpose of the invention, the specific implementation and structure of a Y-shaped water-sealed tank proposed according to the utility model will be described below in conjunction with the accompanying drawings and preferred embodiments. , features and their effects are described in detail below.

The utility model is a Y-shaped water-sealed tank, which includes a cylindrical tank body 2, a communication port, a communication pipe, an overflow port 4, and a water inlet and outlet 5.

The water inlet and outlet 5 are arranged at the bottom of the cylindrical tank body 2, and the overflow port 4 is arranged above the mouth of the communicating pipe.

With the above structure, the smoke can enter the cylindrical tank body 2 from the communication pipe (or communication port), and then flow out from the communication port (or communication pipe). The route the smoke travels in the water-sealed tank is similar to a "U" Combined with this "U" shape, the water-sealed tank looks like a "Y" shape, so the water-sealed tank is called a Y-shaped water-sealed tank.

Example 1

Please refer to FIG. 1 a , which is a schematic diagram of a Y-shaped side-entry top-exit water-sealed tank of the present invention.

Please refer to Figure 1b. When it is necessary to cut off the gas phase medium, open the water inlet and outlet 5 and start water intake. Because the gas phase pressure on the inlet side of the water-sealed tank is high, the pressure on the gas outlet side is low, and there is a pressure difference between the inlet side and the gas outlet side. Under the action of pressure difference, the inlet pipe 1 will be filled with water, and the inlet pipe 1 will be used as a part of the water seal, and when the water entering the water seal tank reaches the equilibrium liquid level, effective sealing will be realized. When the gas phase pipeline needs to be opened, the water inlet and outlet 5 are opened, and the water in the water seal tank flows out from the water inlet and outlet 5. At this time, the gas phase medium enters from the air inlet pipe 1 of the water seal tank, flows out through the flue gas outlet 3, and the pipeline is opened.

Example 2

Please refer to Fig. 2a, which is a schematic diagram of a Y-shaped upper-inlet and side-outer water-sealed tank of the present invention. In this top-in and side-out water-sealed tank, the communication port communicates with the air inlet pipe 1 , and the communication pipe communicates with the flue gas outlet 3 . There are N (1≤N≤10) guide vanes 6 at the connection between the circular tank body 2 and the smoke outlet 3; Down, it flows out through the flue gas outlet 3.

Please refer to Figure 2b. When it is necessary to cut off the gas phase medium, open the water inlet and outlet 5 and start water intake. Because the gas phase pressure on the inlet side of the water-sealed tank is high, the pressure on the gas outlet side is low, and there is a pressure difference between the inlet side and the gas outlet side. Under the action of pressure difference, effective sealing is realized when the water entering the water-sealed tank reaches the equilibrium liquid level. When the gas phase pipeline needs to be opened, the water inlet and outlet 5 are opened, and the water in the water seal tank flows out from the water inlet and outlet 5. At this time, the gas phase medium enters from the air inlet pipe 1 of the water seal tank, flows out through the flue gas outlet 3, and the pipeline is opened.
