Description

Liquefied petroleum ga steel cylinder gasification heater

The utility model relates to a kind of heater, particularly a kind of liquefied petroleum ga steel cylinder gasification heater.

At present, in order to solve town dweller biotope gas supply problem, various places Gas Company is provided with bottle group liquefied petroleum gas supply device in the living area that a part of resident concentrates.But in the winter time or the low cold weather of temperature, the difficult gasification of the liquefied petroleum air exhaustion in the steel cylinder causes in the system supply gas pressure low, and that does not satisfy the resident uses the gas needs.Though installed heating equipment additional between the bottle group that has,,, the gasification of liquefied petroleum gas (LPG) in the steel cylinder do not played much effects so steel cylinder ambient temperature on every side is still lower because the requirement of security against fire aspect makes this building mostly possess good ventilation condition.The effective way that solves this difficult problem is to install the steam raising device on air feeder additional.But, installing this equipment investment cost height additional, floor space is big, has not only increased the investment construction expense, and power consumption energy height, per hour can reach 7.5KW～50KW, and the long-time running cost is also high, and this is the deficiency of existing heating plant.

The purpose of this utility model is a kind of liquefied petroleum ga steel cylinder of invention gasification heater, this gasification heater structure is simple, easy to install, consumes power is few, cost is low, can solve the gasification problem of the interior liquefied petroleum gas (LPG) of steel cylinder under the cryogenic conditions preferably, be convenient to vast northern area gas industry and use, in order to overcome the deficiency of existing heating plant.

The purpose of this utility model can reach by following embodiment: this heater is made up of electrical heating elements, insulation layer, outer protective cover and the interface unit that is connected on steel cylinder, and electrical heating elements is that the electric heating wire heating element promptly is similar to little electric blanket or PTC heating sheet; The insulation layer is heat preserving and insulating material such as asbestos rubber cushion; Outer protective cover is a stainless steel, and other metallic material or nonmetallic material can play a protective role just.Electrical heating elements is at internal layer, and the insulation layer is the second layer outside electrical heating elements.Outer protective cover is the 3rd layer outside the insulation layer.The interface unit that connects on the steel cylinder is that elastic ribbon connects or magnetic attraction connects, and this heater global shape is hood-shaped and partly bind round hood-shaped for full hoop.

Advantage of the present utility model is simple in structure, easy to install, and consumes power is few, cost is low, can solve the gasification problem of the interior liquefied petroleum gas (LPG) of steel cylinder under the cryogenic conditions preferably, be convenient to vast northern area gas industry and use, be a kind of desirable liquefied petroleum ga steel cylinder gasification heater.

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

Figure 10 connects the mounting point figure of heaters set on steel cylinder the time for elastic ribbon;

Key plan when Figure 11 is installed on the steel cylinder for magnetic attraction connects heater.

Shown in Fig. 1～11, this heater is made up of electrical heating elements 1, insulation layer 2, outer protective cover 3 and the interface unit that is connected on steel cylinder 4, and electrical heating elements 1 promptly is similar to little electric blanket or PTC heating sheet for the electric heating wire heating element; Insulation layer 2 is heat preserving and insulating material such as asbestos rubber cushion; Outer protective cover 3 is stainless steel, other metallic material or nonmetallic material; Electrical heating elements 1 is at internal layer, and insulation layer 2 is the second layer outside electrical heating elements; outer protective cover 3 is outside insulation layer 2; be the 3rd layer, the interface unit that connects on the steel cylinder 4 be elastic ribbon connect 5 or magnetic attraction connect 6, this heater global shape is hood-shaped and partly bind round hood-shaped for full hoop.

During use, the band elastic ribbon connects 5 heater for being placed on cylinder for liquefied gas 4 one sides, and the metal button on its both sides elastic ribbon is buckled mutually, to its connection power supply, can start working then.The band magnetic attraction connects 6 heater for being placed on cylinder for liquefied gas 4 one sides, and the magnetic material on it will make itself and steel cylinder 4 adsorbed close together, connects power supply to heater then and gets final product.

The utility model should be noted that following some: 1, heater must meet the requirement of explosion-proof place with being connected of indoor power supply, adopts the explosion-proof electrical source socket, and perhaps the explosion-proof electrical source switch forbids adopting the common power Placement.2, heater power source voltage adds the 220V Ac.3, the operating temperature of heater: regulate arbitrarily in 30～50 ℃.4, control pattern: can adopt any one of three kinds of thermostatic types, Temp. adjustable type, temperature control type.5, the power of electrical heating elements can be four kinds of 20W, 40W, 60W, 80W, and the North China can adopt three kinds of 20W-60W, and northern frore area can adopt three kinds of 40-80W.6, electrically-heated-wire adopts winding type polyethylene multiply contra wire.7, power line adopts copper fiber to knit flexible cord or the fine PVC compound inslation of fourth line, and wire glass is not less than 0.2mm ²Voltage proof is not less than 250V, and electric current is not less than the 3-6 ampere.
