Abstract
The invention relates to a natural-gas heating system of a low-temperature heat-insulation cylinder. The natural-gas heating system comprises a main thermal cycle system and a sub thermal cycle system, wherein the main thermal cycle system comprises a fan (1), a heating chamber (7), a main inlet pipe (5) and a main suction pipe (4), the sub thermal cycle system comprises an auxiliary suction pipe (2), an auxiliary inlet pipe (3) and a cap (9), the cap (9) is provided with a joint I (8) and a joint II (10), one end of the auxiliary suction pipe (2) and one end of the auxiliary air inlet pipe (3) are respectively connected with the main air suction pipe (4) and main air inlet pipe (5), and the other end of the auxiliary suction pipe (2) and the other end of auxiliary air inlet pipe (3) are respectively connected with a product bottom pipeline through the joint II (10) and joint I (8). The invention provides the natural-gas heating system of the low-temperature heat-insulation cylinder, the heating temperature thereof rises rapidly and uniformly, the heating consistency of products is good, and the cost of the unit heating amount is greatly reduced.
Description
Technical field
The present invention relates to a kind of cryogenic insulated cylinder heated by natural gas system.
Background technique
At present, in the industries such as machinery, chemical industry, medicine, need to use the gases such as oxygen, argon gas and nitrogen in a large number, when preparing these gases, then adopt the mode of high pressure compressed to store by high-pressure cylinder, because high-pressure cylinder gas-storing capacity is less, and fill and transport all comparatively inconvenience.Cryogenic insulated cylinder has another name called Dewar vessel, can be used for the cryogenic liquides (also can be described as cryogenic liquid gas) such as storing liquid nitrogen, liquid oxygen, liquified natural gas.Because the gas storage amount of cryogenic insulated cylinder is large, safe and reliable, the storage of liquid gas and transport are facilitated more economically.
Usual cryogenic insulated cylinder is heated by level meter inipple by an electrical heating rod, but electric heating exists, and temperature ramp-up rate is slow, the high in cost of production shortcoming of units of heat.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of cryogenic insulated cylinder heated by natural gas system, its heating-up temperature rises fast and evenly, each product heating high conformity, the cost that unit adds heat significantly declines.
The object of the present invention is achieved like this: a kind of cryogenic insulated cylinder heated by natural gas system, it comprises main heat circulating system and sub-heat circulating system, described main heat circulating system comprises blower fan, heating chamber, main suction tude and main sucking pipe, described sub-heat circulating system comprises secondary sucking pipe, secondary suction tude and block, described block is provided with joint I and joint II, described secondary sucking pipe is connected with main suction tude with main sucking pipe respectively with secondary suction tude one end, described secondary sucking pipe is connected with product bottom conduit with joint I respectively by joint II with the secondary suction tude the other end.
Described main suction tude and main sucking pipe arranged outside have thermal insulating material.
Compared with prior art, the present invention has following beneficial effect:
A kind of cryogenic insulated cylinder heated by natural gas of the present invention system, its temperature constant, does not need single heater to install temperature measuring equipment, can prevent the damage of single heating pipe or long-time use from causing the heating of each product inconsistent yet; Secondly because gas is circulation, heated by natural gas speed rises fast than electric heating speed, and evenly, there is not each product and heat inconsistent problem; Again, although strengthen in economic aspect equipment investment, the cost that unit adds heat has significant decline.

Embodiment
See Fig. 1, Fig. 2, a kind of cryogenic insulated cylinder heated by natural gas of the present invention system, it comprises main heat circulating system and sub-heat circulating system, described main heat circulating system comprises blower fan 1, heating chamber 7, main suction tude 5 and main sucking pipe 4, described sub-heat circulating system comprises secondary sucking pipe 2, secondary suction tude 3 and block 9, described block 9 is provided with joint I8 and joint II10, described joint I8 is positioned at block 9 side, described joint II10 is positioned at block 9 top, described secondary sucking pipe 2 is connected with main suction tude 5 with main sucking pipe 4 respectively with secondary suction tude 3 one end, described secondary sucking pipe 2 is connected with product bottom conduit with joint I8 respectively by joint II10 with secondary suction tude 3 the other end.
Described main suction tude 5 and main sucking pipe 4 arranged outside have thermal insulating material 6, and thermal insulating material 6 pairs of whole systems and extraneous shield heat away, make thermal cycle carry out efficiently in order.
Hot gas because the suction of density and blower fan upwards enters main sucking pipe by secondary sucking pipe, ensure that heat exchange area, the uniformity of heating and rate of heating in the product.
