Description
Technical field：
The utility model is related to a kind of electric heating water bath heat exchangers, especially to oneself of heated by natural gas or nitrogen heating
The device of right convection current heat transfer.
Background technology：
Nitrogen extensive use in many industries, generally use directly purchase liquid nitrogen, then by being used after gasification, and winter is empty
Gas temperature after gas heating and gasifying is relatively low, cannot directly use, and there is electric heating water bath heat exchanger heat exchange to stablize, use peace
Congruent feature has been widely used and this field.And the gasification process of liquified natural gas is close with liquid nitrogen gasification technique, electrical heating
Water-bath type heat exchanger is in this field also extensive use.
The electric heating water bath heat exchanger generally used currently on the market is placed on one using electric heater and heat exchange coil
Arrangement in a cylinder, in operational process, farther out or resistance due to hot water or cold water wadding stream in water-bath and from heating location
The mobility of big position water is poor, causes heat exchange efficiency low, makes equipment system by increasing heat exchange area improvement heat transfer effect
It causes originally to increase.
Water-bath type electric heater unit disclosed in CN102635943A changes the flow field of water, avoids using guide shell is increased
Hot water or cold water wadding stream, improves heat exchange efficiency.But this method can be only formed the circumferential flowing of vertical direction, and flow velocity increase has
Limit, if can increase flowing velocity, will further improve exchange thermal effect.
Invention content：
The purpose of this utility model is that in view of the above shortcomings of the prior art, provides a kind of electric heating water bath heat exchange
Device.
The invention thought of the utility model：One is further added by the cylinder of water-bath type heat exchanger has spiral stream guidance channel
Inner cylinder, by support, there are a fixed gaps with outer barrel bottom for inner cylinder bottom, and heat exchange coil is arranged between interior outer barrel,
Inner cylinder bottom is evenly arranged electric heater, inner cylinder Central Closed, and fluid only passes through helical duct.When heating, in inner cylinder
Internal helicoid rise, flow out inner cylinder when the circumferential flow velocity with horizontal direction, between outer barrel and inner cylinder liquid helically to
Lower flowing has higher heat transfer coefficient.
The purpose of this utility model is achieved through the following technical solutions：
A kind of electric heating water bath heat exchanger is in the arc-shaped by the top of outer barrel 1, and equipped with gas vent 11, gas
The outer contact 5 of import 7, gas vent 8 and electric heater, the side wall of outer barrel 1 are equipped with embedded liquid level gauge 3, filler 9, temperature
Measuring mouth 12 and leakage fluid dram 10, outer barrel 1 is interior to be equipped with inner cylinder 2, is ring-shaped cavity, heat exchange plate between outer barrel 1 and inner cylinder 2
Pipe 6 is placed in ring-shaped cavity, and 2 bottom of inner cylinder is equipped with electric heater 4, and the electricity that electric heater 4 is equipped with 1 top of outer barrel adds
Contact 5 connects and composes outside hot device.
Heat exchange coil 6 is fixed on 2 outer wall of inner cylinder, and the inner wall of outer barrel 1 and the inner wall of inner cylinder 2 are respectively equipped with spiral
Flow-guiding channel.
Water in inner cylinder 2 flows from bottom to top along spiral stream guidance channel, and outer barrel 1 and the water of inner cylinder 2 are led along spiral
Circulation road flows from top to bottom, forms free convection heat transfer.
Advantageous effect：The utility model makes water be formed in container with circumferential and vertical by increasing spiral stream guidance channel
To the spiral shape flow field of flowing, solve the problems, such as that natural flowing velocity is slow in water bath heating device, greatly improves heat exchange
Efficiency.Since in interior inner barrel, heating, water has level to heater in interior inner barrel spiral when flowing out inner cylinder
The circumferential flow velocity in direction, liquid helically flows downward between outer barrel and inner cylinder, has higher heat transfer efficiency.

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples：
A kind of electric heating water bath heat exchanger is in the arc-shaped by the top of outer barrel 1, and equipped with gas vent 11, gas
The outer contact 5 of import 7, gas vent 8 and electric heater, the side wall of outer barrel 1 are equipped with embedded liquid level gauge 3, filler 9, temperature
Measuring mouth 12 and leakage fluid dram 10, outer barrel 1 is interior to be equipped with inner cylinder 2, is ring-shaped cavity, heat exchange plate between outer barrel 1 and inner cylinder 2
Pipe 6 is placed in ring-shaped cavity, and 2 bottom of inner cylinder is equipped with electric heater 4, and the electricity that electric heater 4 is equipped with 1 top of outer barrel adds
Contact 5 connects and composes outside hot device.
Heat exchange coil 6 is fixed on 2 outer wall of inner cylinder, and the inner wall of outer barrel 1 and the inner wall of inner cylinder 2 are respectively equipped with spiral
Flow-guiding channel.
Water in inner cylinder 2 flows from bottom to top along spiral stream guidance channel, and outer barrel 1 and the water of inner cylinder 2 are led along spiral
Circulation road flows from top to bottom, forms free convection heat transfer.
Device goes into operation front and back, and the valve of gas vent 11 is constantly in open state, before device goes into operation, by filler 9 to
Outer barrel 1 plus water observe liquid level by liquid level gauge 3, when the water of addition is more than heat exchange coil certain altitude, stop adding water.
After device goes into operation, by electric heater 4 to heating water bath, water temperature is measured according to thermometer 12, controls electric heater,
It is passed through by gas access 7 and needs heat gas, by heat exchange coil 6 by heat transfer in water to gas, heat transfer process is reverse
Convection current, gas leaves electrical heating water-bath heat exchanger by gas vent 8 after heat exchange.
By becoming high-temp liquid after electrical heating, liquid flows up liquid in 2 inside spin of inner cylinder, interior in inner cylinder 2
Liquid cooling downward spiral flowing, coil heat exchange process form free convection after 2 outside liquid of cylinder exchanges heat with heat exchange coil 6
Helical flow increases heat transfer coefficient, increases heat transfer temperature difference, and then increase heat transfer efficiency.
Electric heater 4 is introduced from top end socket, is distributed in 2 bottom of inner cylinder, and when heating can effectively prevent inside inner cylinder 2
Back-mixing, heating process are stablized.
