Abstract

The utility model relates to a torch water-sealed tank liquid level pressure maintaining device, belongs to the field of a torch water-sealed tank liquid level maintaining technology, and aims at providing a torch water-sealed tank liquid level pressure maintaining device which can effectively maintain the liquid level of a water-sealed tank and adapts to high-temperature and high-pressure flare gas. The utility model adopts the technical scheme that the torch water-sealed tank liquid level pressure maintaining device comprises the water-sealed tank, a liquid storage tank, an overflow pipe and a pressure guide pipe, wherein the liquid storage tank is arranged under one side of the water-sealed tank; the bottom of the liquid storage tank is communicated with the interior of the water-sealed tank by the overflow pipe; the mounting position of the overflow pipe on the water-sealed tank corresponds to that of the set liquid level; one end of the overflow pipe, arranged in the water-sealed tank, extends to the bottom of the water-sealed tank; the upper part of the water-sealed tank is communicated with the upper part of the liquid storage tank by the pressure guide pipe; the overflow pipe is communicated with the pressure guide pipe by a siphon breaking pipe. The torch water-sealed tank liquid level pressure maintaining device is arranged on the torch water-sealed tank and can be used for maintaining the liquid level in the water-sealed tank.

Description

Torch water sealed tank liquid level pressurizer

Technical field

The utility model torch water sealed tank liquid level pressurizer, belong to torch water sealed tank liquid level and keep technical field.

Background technique

Traditional water sealed tank spill pipe, when torch gas pressure is higher, because needs spill pipe effective height is higher, makes the water sealed tank height significantly improve, and simultaneously, makes water sealed tank manufacture cost and maintenance cost improve; On the other hand, the temperature of torch gas is very high, sometimes reaches 210 ℃, is easy to, by vaporizing liquid in spill pipe, torch gas be discharged from spill pipe, causes serious disaster hidden-trouble and personal safety hidden danger.

The model utility content

The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is to provide a kind of effective maintenance water sealed tank liquid level, can adapt to the torch water sealed tank liquid level pressurizer of high temperature, high pressure flare gas simultaneously.

In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: torch water sealed tank liquid level pressurizer, comprise water sealed tank, liquid container, spill pipe and pressure inlet tube, liquid container is positioned at the below of water sealed tank one side, the bottom of liquid container is by the internal communication of spill pipe and water sealed tank, and the mounting point of spill pipe on water sealed tank is corresponding with the setting liquid level, the end that described spill pipe is positioned at water sealed tank inside stretches to the bottom of water sealed tank, the top of water sealed tank and the top of liquid container are connected by pressure inlet tube, described spill pipe and pressure inlet tube are connected by broken tube.

The bottom of described liquid container is equipped with drain valve.

The utility model torch water sealed tank liquid level pressurizer compared with the existing technology has following beneficial effect.

1, the utility model arranges a liquid container outside water sealed tank, and the liquid container bottom is connected by spill pipe with the setting liquid level of water sealed tank, make to exceed the liquid of setting liquid level and can flow into liquid container from spill pipe, the top of water sealed tank and liquid container is communicated with by pressure inlet tube simultaneously, water sealed tank and liquid container internal pressure are maintained an equal level, avoid because the water sealed tank internal pressure is excessive and bottom liquid is pressed in liquid container from spill pipe, make the continuous moisturizing of water sealed tank continuous blow-down, guaranteed the normal operation of water sealed tank; And, because liquid container does not directly contact with torch gas, steam output is lower, the end that spill pipe is positioned at water sealed tank stretches to the water sealed tank bottom, and the emptying gas in water sealed tank can directly externally not discharge yet, and has guaranteed safety in utilization of the present utility model.

2, in the utility model, liquid container is positioned at the below of water sealed tank, one broken tube is set on spill pipe to be connected with pressure inlet tube, pressure inlet tube is to air feed in spill pipe, can prevent from, in spill pipe, siphonage occurs and the water sealed tank bottom liquid is sucked in liquid container continuously, guarantee the normal operation of water sealed tank.

3, the use of the utility model pressure inlet tube and broken tube, make it when only liquid level surpasses the setting liquid level in water sealed tank, could flow into liquid container, spill pipe does not just need to arrange as tratitional technology very high, and the design height simultaneously also water sealed tank required reduces, and has reduced making and maintenance cost.

The accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The structural representation that Fig. 1 is the utility model torch water sealed tank liquid level pressurizer.

In figure: 1 is water sealed tank, and 2 is liquid container, and 3 is spill pipe, and 4 is pressure inlet tube, and 5 is broken tube, and 6 is drain valve.

Embodiment

As shown in Figure 1, the utility model torch water sealed tank liquid level pressurizer, comprise water sealed tank 1, liquid container 2, spill pipe 3 and pressure inlet tube 4, liquid container 2 is positioned at the below of water sealed tank 1 one sides, the bottom of liquid container 2 is the internal communication with water sealed tank 1 by spill pipe 3, and the mounting point of spill pipe 3 on water sealed tank 1 is corresponding with the setting liquid level, the end that described spill pipe 3 is positioned at water sealed tank 1 inside stretches to the bottom of water sealed tank 1, the top of the top of water sealed tank 1 and liquid container 2 is connected by pressure inlet tube 4, and described spill pipe 3 and pressure inlet tube 4 are connected by broken tube 5.

The bottom of described liquid container 2 is equipped with drain valve 6.

The liquid container 2 increased in the utility model has guaranteed that the emptying gas in water sealed tank 1 can directly externally not discharge, and has improved Security, has guaranteed the normal operation of water sealed tank 1 simultaneously.

Be positioned at and set liquid level when following at the interior liquid level of water sealed tank 1, the utility model normal operation, water sealed tank 1 top and liquid container 2 are communicated with by pressure inlet tube 4 simultaneously, its internal pressure is maintained an equal level, avoid water sealed tank 1 internal air pressure excessive and liquid is pressed into to liquid container 2 by spill pipe 3, make the continuous moisturizing of water sealed tank 1 continuous blow-down, guaranteed the normal operation of water sealed tank 1;

When the interior liquid of water sealed tank 1 when setting liquid level, unnecessary liquid flows to liquid container 2 by spill pipe 3, unnecessary liquid all flows to liquid container 2 and when making liquid level in water sealed tank 1 and setting liquid level and maintain an equal level, because liquid container 2 is positioned at the lower position of water sealed tank 1, the interior easy generation siphonage of spill pipe 3 and by the liquid in water sealed tank 1 continuously in suction liquid container 2, and the broken tube 5 in the utility model, spill pipe 3 is communicated with pressure inlet tube 4 is to the interior air feed of spill pipe 3, avoided the generation of siphonage, so just can make water sealed tank 1 realize that liquid level keeps.

Because pressure inlet tube 4 and broken tube 5 have been avoided because the interior pressure of water sealed tank 1 is crossed the generation that senior general's liquid is pressed into liquid container 2 and these two kinds of situations of siphonage, only guarantee to surpass while setting liquid level and just can make liquid flow in liquid container 2 at the interior liquid level of water sealed tank 1, therefore just do not need to arrange very highly by spill pipe 3, reduce equally the height of water sealed tank 1, saved manufacture and maintenance cost.
