Technical field
It ferments the present invention relates to sewage through anaerobic reaction and generates the equipment technical field of biogas, be specifically related to one kind and be based on
The IC reactor heating system of jet dynamic control and compression heat pump.
Background technique
IC reactor is the high efficiency anaerobic reactor that Dutch Paques company succeeds in developing the eighties.The spy of IC reactor
Point is that biogas is divided into two stages in a high reactor, and lower reaction zone is in high load capacity, and upper reaction zone is in
Underload, the biogas that following reaction zone generates do power, realize circulation in lower reaction zone mixed liquor, obtain waste water and strengthen pre- place
Reason；Top reaction zone continues to post-process to waste water simultaneously, and water outlet is made to reach expected Anaerobic Treatment (at [1] IC reactor
Manage piggery wastewater experimental study _ Huang Zhiping).Due to the optimum growth temp of most anaerobic bacterias (mainly methane backeria and hydrolytic bacteria)
At 30-35 DEG C, so suitable environment temperature and lesser temperature fluctuation is the stable essential condition of IC reactor ([2]
Operation characteristic research _ Liu Guangliang of UASB_IC reactor for treatment organic wastewater), exist in view of many cities in this factor China
It can all be substantially reduced using efficiency when IC reactor in winter, treated, and sewage is often difficult to meet the requirements.
In order to which the temperature guaranteed in reactor maintains in a more constant range, traditional method mostly uses biogas
The mode (design-Zhao Jinhui of [3] solar energy _ methane boiler and methane-generating pit association system) of boiler, but methane boiler utilizes
Efficiency is lower, and partial heat can be discharged with flue gas.More importantly contain a large amount of waste heat, but nothing in IC reactor outlet waste water

It is characterized in that, there are two types of operational modes for the system: the first operational mode is the inlet effluent temperature in IC reactor (5)
When lower, outlet waste water temperature is relatively high, and the waste heat recycling heat import that can combine jet dynamic control (14) is useless
Water；Second of operational mode is when IC reactor (5) inlet effluent temperature is higher, and jet dynamic control (14) combines compression
Heat pump system, the heat of the outlet waste water of compression heat pump system recycling at this time and the waste heat and cylinder of jet dynamic control (14)
The inlet effluent of set recycling heat IC reactor (5), maintains the temperature of IC reactor (5) most preferably in whole year
In temperature range.
4. a kind of IC reactor heating system based on jet dynamic control and compression heat pump according to claim 3,
It is characterized in that, the first described operational mode specifically: when the inlet effluent water temperature of IC reactor (5) is lower, IC reaction
The outlet waste water of device (5) directly heats inlet effluent through heat exchanger II (3) first；The biogas that IC reactor (5) generates is sent to
Jet dynamic control (14) generates electricity, and recycles recirculated water by the exhaust gas heat exchanger (11) and waste heat of jet dynamic control (14)
Device recycles the waste heat of unit flue gas, and is used for heating the inlet effluent after heat exchanger II (3).
5. a kind of IC reactor heating system based on jet dynamic control and compression heat pump according to claim 3,
It is characterized in that, second of operational mode specifically: when the inlet effluent water temperature of IC reactor (5) is higher, outlet is useless
Water can not be heated directly for inlet effluent, and biogas enters jet dynamic control (14) and generates electricity at this time, and the electricity of generation is for driving
Waste heat in dynamic compression heat pump system recycling outlet waste water, removal process are exchanged heat using indirect type, and the heat of recycling adds first
Then hot inlet effluent heats inlet effluent by heat exchanger III (4) by the heat of the jet dynamic control (14) recycled again.
