Method for cooling a thermoreactor and system thereof

Abstract

A method for cooling a thermoreactor and system thereof, having a noncombustible function for chemical materials pyrolysis in a hot thermoreactor that also lowers the temperature inside the hot thermoreactor, and a method for exhausting pyrolysis oil gas from a thermoreactor after batch type heating, pouring N 2 or inert gas into the thermoreactor for cooling the gas until the thermoreactor achieves a predetermined pressure, and finally circulating cooling from thermoreactor; the system equipment includes a thermoreactor, a heat exchanger, a mixed gas thermoreactor, a circulation pump and a greaves settling thermoreactor.

1 . A method for cooling a thermoreactor, comprising: 
 (1) exhausting pyrolysis oil gas from the thermoreactor until the thermoreactor achieves a predetermined pressure or temperature after batch type heating;    (2) pouring N 2  or an inert gas into the thermoreactor to cool the oil gas until the thermoreactor achieves a predetermined pressure or concentration; and    (3) circulating cooling from the thermoreactor connected to a heat exchanger until the thermoreactor achieves a predetermined lower temperature range.    
   
   
       2 . The method as claimed in  claim 1 , wherein in the step ( 1 ) the predetermined pressure range is 1.3 to 0.7 atm.  
   
   
       3 . The method as claimed in  claim 1 , wherein in the step ( 1 ) the predetermined temperature range is 300° C. to 600° C.  
   
   
       4 . The method as claimed in  claim 1 , wherein in the step ( 1 ) the predetermined pressure range is 2.6 to 1.4 atm.  
   
   
       5 . The method as claimed in  claim 1 , wherein the heat exchanger is ice water to gas for heat exchanging.  
   
   
       6 . The method as claimed in  claim 1 , wherein the predetermined lowered temperature range is 80° C. to 40° C.  
   
   
       7 . A system for cooling a thermoreactor, comprising: 
 A thermoreactor, having an entry hole for the N 2  or an inert gas and an exhaust hole for the mixed oil gas;    a heat exchanger, having a frame for a refrigerant to mix with the oil gas for heat exchanging;    a mixed gas storage thermoreactor, having an entry and an exhaust hole for the cooling mixed oil gas; and    a circulation pump, connecting the thermoreactor and the heat exchanger and the mixed gas storage thermoreactor;    wherein the circulation pump connecting the thermoreactor and the heat exchanger, forms the first circulating cooling circuit.    
   
   
       8 . The system as claimed in  claim 7 , wherein the circulation pump connecting the thermoreactor, the heat exchanger and the mixed gas storage thermoreactor, forms the second circulating cooling circuit.  
   
   
       9 . The system as claimed in  claim 7 , further includes a greaves settling thermoreactor connected to the thermoreactor.  
   
   
       10 . The system as claimed in  claim 7 , wherein the refrigerant of the heat exchanger is ice water or cool water.  
   
   
       11 . The system as claimed in  claim 10 , wherein the heat exchanger has two-stages of cooling the mixed oil gas, the first using ice water and the second using cool water.
