It is able to achieve the uninterrupted operation of freezing removal process in the freezing recovery device of double heat exchanger, and has saved defrosting energy consumption.
The technical solution of utility model is as follows：
A kind of freezing recovery device based on double heat exchanger, including boiler（1）, cold water storage cistern（6）, 2 heat exchangers and
At least two solenoid valve；
2 heat exchangers are arranged in parallel, and in 2 heat exchangers, First Heat Exchanger and the second heat exchanger rotation work are changed when one
When hot device is for freezing recycling, another heat exchanger is for defrosting.（Two heat exchangers of rotation work carry out in turn freezing recycling and
Defrosting process；）
The solenoid valve is 10,2 for freezing water inlet, 2 for freezing return water, 2 for molten white hot water into
Water, 2 are used for molten white hot water backwater, and 2 are used for air inlet.
The heat exchanger is case tube heat exchanger（7）.
Freezing recovery device based on double heat exchanger further includes one and changes for recycling the board-like of heat in compressor air-discharging
Hot device.（Frame of reference flow chart, recuperation of heat have an individual plate heat exchanger for recycling the heat in compressor air-discharging.
Chilled water and the gas heat exchange to be returned when two package exchanging airs in parallel are not connected or recycle with compressor；?
Hot water and the ice of condensation exchange heat when molten frost）.Two freezings recycling heat exchangers in parallel are rotation works, one in defrosting,
Another just freezes recycling], two attachment devices be it is identical, pass through electromagnetism Vavle switching.
When recycling, cold water enters the exhaust gas heat exchange in recycling case tube heat exchanger tube side and shell side by evaporator cooling,
Cold water after heating returns to cold water storage cistern, and the recycling ingredient freezing in exhaust gas is that recovered liquid is discharged, and other gases are discharged to exhaust pipe；
When molten frost, hot water enters in recycling case tube heat exchanger tube side and shell side by heat regenerator heating freezes ingredient
(water-setting in exhaust gas build-ups ice) heat exchange, returns to boiler for the hot water after temperature, freezes ingredient (ice) to melt to be that water passes through back
Is discharged at this time in liquid receiving mouth, and air inlet, exhaust outlet is in close state.
Freezing recovery device based on double heat exchanger further includes electric heated defrosting device.
Freezing recovery device based on double heat exchanger further includes explosion-protection equipment, is equipped with anti-explosion terminal box in explosion-protection equipment
（15）.
Beneficial effect：
The freezing recovery device based on double heat exchanger of the utility model, recycling compressor air-discharging end waste heat replace traditional
Electric heater is as defrosting heat source, energy saving.By two heat exchangers in parallel, a freezing recycling, a defrosting, two are changed
Hot device works alternatively the uninterrupted operation for realizing freezing recovery operation.It is worked alternatively with recuperation of heat hot water defrosting's double heat exchanger cold
Freeze recyclable device, overcome problem of the prior art, be able to achieve the uninterrupted operation of freezing removal process, and saves defrosting
（Defrosting）Energy consumption.

Specific embodiment
The utility model is described in further details below with reference to the drawings and specific embodiments：
Embodiment 1：Shown such as Fig. 1-5, the freezing recovery device based on double heat exchanger of the utility model can recycle compression
Heat source of the waste heat of machine exhaust as defrosting only throws electric heater unit in shortage of heat using electric heater unit as auxiliary
Enter to use, to reduce the power consumption of defrosting process.It is worked alternatively using two heat exchangers in parallel, a freezing recycling, one
A defrosting guarantees the uninterrupted operation of freezing removal process.The main component of equipment includes：Boiler, cold water storage cistern, hot defrosted water
Pump, heat regenerator, compressor, condenser, expansion valve, evaporator, water supply pump, solenoid valve, recycling heat exchanger etc..
The treasured that the device is used to recycle in exhaust gas is made every effort to overcome（Specific recovery process and recyclable device are existing mature technology）,
