Abstract

The technic proposal of the utility model relates to a liquefied petroleum gas tank which comprises an upper tank that stores low pressure gaseous liquefied gas and a lower tank stores high pressure liquid liquefied gas, and the volume ratio of the upper tank and the lower tank is from 1 : 1 to 1 : 5. The upper part of the upper tank is provided with a gas outlet valve of the gaseous liquefied gas, and the top of the upper tank is provided with a gas inlet valve of the liquid liquefied gas. The gas outlet valve is directly communicated with the upper tank, and the gas inlet valve of the liquid liquefied gas is directly connected with a nozzle which goes through the bottom of the lower tank, and a filter screen is arranged at the bottom of the nozzle. A pressure reducing valve is arranged between the upper tank and the in and out pipeline of the liquid liquefied gas, making the liquid liquefied gas go from the bottom of the lower tank, the nozzle, the pressure reducing valve to the upper tank to gasify, thus avoiding the residual liquid when the liquefied gas is gasified.

Description

A kind of petroleum oil liquid gas storage tank

Technical field

This liquefied petroleum gas tank belongs to the pressurized container field.

Background technique

The liquefied petroleum gas tank that uses is the stress metal jar of a hollow now.The angle valve that can the can liquefied petroleum gas can give vent to anger is again adorned at its top.Pour into a certain amount of liquefied petroleum gas (LPG) before using earlier in jar, the liquefied petroleum gas (LPG) liquid volume is about about 2/3 of jar inner volume.Open the gas tank crown valve during use.To the burner burning, this liquefied petroleum gas tank can produce LPG (liquefied petroleum gas) residual liquid to gaseous liquefied petroleum gas, and is both uneconomical, dangerous again through reduction valve in jar.This patent is the development to my application number " 200510104650.1 " patent of invention.

Summary of the invention:

The present invention aims to provide a kind of full composition of liquefied petroleum gas (LPG) that can make gasifies, and fully burns, and does not stay a kind of petroleum oil liquid gas storage tank of raffinate.

The technological scheme of this patent is a kind of petroleum oil liquid gas storage tank, comprise two disjunctor jars up and down, it is characterized in that: go up jar (1) top gas outlet valve (6) is installed, following jar (2) are contained in the bottom, liquid city gas bottling valve (5) is installed in last jar of (1) open top, this valve and adapter (4) are communicated to down jar (a 2) bottom, and dress filter screen (3), and liquid gas can be gone up current downflow in taking over (4).The volume of last jar (1) is 1: 1～1: 5 with the ratio of the volume of following jar (2).

As a kind of improvement, following jar (1) bottom is provided with filter screen (3), the liquid liquefied petroleum gas (LPG) enters adapter (4) by the filter screen (3) of following jar (2) bottom, its diameter is the metal tube of 10-30mm, and the last tank skin that this adapter is passed up and down jar enters reduction valve (7) and and seals between the upper cover of jar up and down.Reduction valve described here (7) has two kinds of mounting points: a kind of is to place jar (a 1) top, as Figure of description; A kind of is to be installed among jar (1), as Figure of abstract.Two kinds of installation methods, a purpose is about to reduce pressure to low pressure liquefied gas and gasification in last jar (1) through reduction valve (7) from the liquid lng of taking in (4), draws burning from the gas outlet valve (6) of last jar (1) at last.The principle of technical solution of the present invention is:

Liquefied petroleum gas (LPG) is the mixture that contains alkane (alkene) hydrocarbon of 2 carbon atom to 5 carbon atoms in the molecule.Because the difference of boiling point each other of each component in the liquid gas, relative hundred parts of content of the low-boiling so-called light component in the gas phase always are higher than relative hundred parts of content of the light component in the liquid phase, become constantly carrying out of divided combustion along with this, cause the light component in the gas phase less and less, air pressure is also more and more low, and the hundred parts of content of difficult gasification composition in the liquid phase are more and more high, and dropping to burning up to air pressure can't carry out, still residual aphlogistic liquid in the jar mainly are pentanes at this moment.This patent aims at the deficiency that solves liquefied petroleum gas tank generation raffinate and invents.The burning of this patent system is finished like this: the highly pressurised liquid liquid gas during lower floor's liquid storage is irritated enters through filter screen to be taken over and reduction valve, enters upper strata jar gasification after the decompression, and then guides to the burner burning from the top gas outlet valve.

In this patent, reduction valve has reduced the boiling point of liquid gas, has realized that liquid gas all gasifies, and fully raffinate is not stayed in burning.

Adopt the expection benefit of the art of this patent scheme

The enforcement of this patent is to national liquefied petroleum gas (LPG) user, and particularly northern city millions of users can reduce expenses, and saves high-grade energy, also fundamentally stops the environmental pollution and the security incident that cause owing to random raffinate.

Description of drawings

Accompanying drawing is two kinds of structural representations of liquefied petroleum gas tank.

Specific implementation method

The following jar diameter of this patent liquefied petroleum gas tank is 324mm, highly be 400mm, two ends are ellipsoidal heads, the thin-walled upper cover of a diameter 326mm of last jar of top weldering, keep the shell total height still with present liquifier jar height 550mm, but topping up gasification 12kg in irritating.A liquid lng can valve and a cock-type gas outlet valve are installed in last tank top.Suction valve is connected with a pipeline that leads to down pot bottom.This pipeline gets 3/4 " galvanized pipe, filter screen is adorned in the pipe bottom; Gas outlet valve directly is communicated with last jar.Desirable two kinds of the mounting point of reduction valve: a kind of is when the reduction valve reliable in quality, in can being built in jar, promptly on passing jar 3/4 " pipeline tapping connects reduction valve, and post-decompression liquid flows directly into and jar gasifies; Another kind is changed reduction valve for ease of maintenance, reduction valve need be placed tank deck, and reduction valve one end is communicated with an end and 3/4 with last jar, and " pipeline is connected, and reduction valve is imported and exported and added stop valve.

Claims

1, a kind of petroleum oil liquid gas storage tank, it is characterized in that: be in the bottom based on jar (1) on the storage low pressure gaseous state liquid gas on following jar (2) of storage high-pressure liquid liquid gas and its top of block set, the volume of last jar (1) is 1: 1～1: 5 with the ratio of the volume of following jar (2), last jar of (1) top is installed into the valve (5) of liquid lng, this valve and adapter (4) are communicated to down jar (2) bottom and adorn filter screen (3), gas liquefaction gas gas outlet valve (6) is also installed on last jar of (1) top, taking over spending road, (4) top dress reduction valve (7), post-decompression low pressure liquid returns jar (1), all gasification.
