Abstract

The utility model relates to a double spiral reverse flow heat exchanging heater for cool and boiling water. The utility model is provided with a boiling water pot whose interior is provided with an electric heater, and the outside of the boiling water pot is provided with two spiral heat exchanging slices. Both ends of each heat exchanging slice are provided with cover plates, and thus, two spiral sealing channels are formed. The end parts of the outer rings of the two spiral sealing channels are respectively provided with a water inlet pipe and a water outlet pipe, and the end parts of the inner rings of the two spiral sealing channels are respectively communicated with the boiling water pot. The utility model has the advantages that the water flow of the raw water and the boiling water can flow in a mutually reverse way, and thus, the utility model can simultaneously raise the temperature of the raw water and refrigerate the boiling water. The utility model has quick and thorough heat exchange, low energy consumption and high efficiency.

Description

Double helix countercurrent flow cooling water device

The utility model belongs to a kind of boiled water process units, particularly a kind of double helix countercurrent flow cooling water device.

In the production of various beverages, all to use a large amount of boiled waters, just cold water usually.Because contain various bacteria and microorganism in the unboiled water, have only boiled after, could kill bacteria and microorganism, guarantee the quality of beverage.In the prior art, this class boiled water uses water heater boiled usually, and water heater has coal water heater, fuel oil type water heater and electrical heating type water heater.In the production of beverage, after water is boiled, can not directly use, also need boiling water is cooled, therefore, the production process of boiled water is longer, and energy consumption height, efficient are low, and when boiling water cooled, the heat in the water can not effectively be used, and the waste of heat energy is very big.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the double helix countercurrent flow that a kind of energy consumption is low, efficient is high cooling water device is provided.

The utility model is achieved in that

It has a boiled water tank, electric heater is housed in the boiled water tank, two spirality heat exchanger fins are housed in the outside of boiled water tank, cover plate is equipped with at two ends at heat exchanger fin, constitute two spirality closed channels, end, outer ring at two spirality closed channels is equipped with oral siphon and outlet pipe respectively, and the inner ring end of two spirality closed channels joins with boiled water tank respectively.

In order to make water in the boiled water tank remain on 95 ℃～100 ℃ thermal equilibrium state, in the outside of boiled water tank the heat exchanger fin inner core is housed, in the heat exchanger fin inner core insulation material is housed.

Advantage of the present utility model is:

1, the arranged outside at boiled water tank has two spirality closed channels, unboiled water and boiling water are respectively walked a passage, and living, boiling water stream is mutually reverse flow, the intensification of unboiled water and the cooling of boiling water are carried out simultaneously, heat exchanger fin is a separation layer, be again heat-transfer surface, heat exchange is thorough fast, and unboiled water absorbs the heat of boiling water in the process that flows into boiled water tank, heat up gradually, when entering boiled water tank, water temperature is near 95 ℃, as long as replenish the sub-fraction heat again, can reach 95 ℃～100 ℃, thereby energy consumption is lower, compares energy-conservation up to more than 98% with the electrical heating type water heater; And boiling water is the outside process of flowing from boiled water tank, and its heat is absorbed by unboiled water gradually, has both effectively utilized the heat energy in the boiling water, shortened the process of producing again, improved the efficient of producing.

2, simple in structure, be skillfully constructed, volume is little, in light weight, materials are economized, cost is low, is suitable for beverage and food production enterprise and uses.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in drawings, the utility model has a boiled water tank 8, boiled water tank 8 is a cylindrical shape, its upper end closed, lower ending opening, electric heater 20 and electric heater 21 are housed in boiled water tank 8, so that controlled respectively, described electric heater 20 and electric heater 21 are fixed on the flange 19, and flange 19 usefulness screws 22 are fixed on the opening of boiled water tank 8, between boiled water tank 8 and flange 19, sealing gasket 23 is housed also, in case leak-stopping water; On the top of boiled water tank 8 blast pipe 12 is housed, is connected to heat resistant plastice flexible pipe 9 on the blast pipe 12, and join by tube connector 11 and air bleeding valve 10, air bleeding valve 10 can run out the steam that produces when water seethes with excitement, and to avoid danger; Temperature control sampling copper sheet 15 also is housed on the top of boiled water tank 8, on temperature control sampling copper sheet 15, temperature controller 13 and temperature controller 14 are housed, the control temperature of temperature controller 13 is 95 ℃, and the control temperature of temperature controller 14 is 100 ℃, so that the temperature of boiling water is controlled at 95 ℃～100 ℃; In the outside of boiled water tank 8 heat exchanger fin inner core 6 is housed, insulation material 7 is housed in the heat exchanger fin inner core 6, boiling water in the boiled water tank 8 are remained in 95 ℃～100 ℃ the scope; In the outside of boiled water tank 8, the outside of heat exchanger fin inner core 6 two spirality heat exchanger fins 4,5 are housed, distance between heat exchanger fin 4 and the heat exchanger fin 5 can be determined according to the size of water consumption, cover plate 3 is equipped with at two ends at

heat exchanger fin

4,5 respectively, closed at both ends with

heat exchanger fin

4,5, thereby constitute two spirality closed channels, in the end, outer ring of two spirality closed channels oral siphon 2 and outlet pipe 17 are housed respectively, valve 1 is housed on the oral siphon 2, valve 18 is housed, so that entry and water outlet are regulated and controlled on the outlet pipe 17; Article two, the inner ring end of spirality closed channel joins with boiled water tank 8 respectively by tube connector 16, constitutes the passage into and out of current.

During use, in the utility model, fill with earlier water, by

electric heater

20,21 that the water in the boiled water tank 8 is boiled again, open valve 1 and valve 18 then, the utility model promptly enters normal operating conditions, article two, the water in the spirality closed channel begins to flow simultaneously, unboiled water inwardly flows from the outer ring, boiling water then outwards flows from inner ring, both are in 4,5 isothermal reverse flows of heat exchanger fin, carry out heat exchange, the unboiled water of inflow absorbs the heat of the boiling water that flows out, and is warmed up to the temperature that is close with boiled water tank 8 gradually; Then cooling gradually in flowing of boiling water, when waiting to flow to delivery port, its temperature is close with the unboiled water temperature of water inlet, outflow be exactly cold water, can directly use.
