Chemical heat storage device

Abstract

A chemical heat storage device that heats a heating target provided in an exhaust pipe 3 from an outer periphery of the heating target, comprising a reactor 9 A that contains reaction materials 9 a that generate heat by chemical reaction with a reaction medium, an adsorber that adsorbs the reaction medium with an adsorbent to store the reaction medium, and branch pipes 11 a and 11 b that connect the adsorber and the reactor 9 A. The reactor 9 A is provided around an outer peripheral surface of a portion at which the heating target is provided in the piping, and includes a plurality of inlet-outlets 9 c and 9 d through which the reaction medium is fed. The plurality of inlet-outlets 9 c and 9 d are arranged so as to be at equal intervals in a circumferential direction of the reactor 9 A without being positioned in a lower portion of the reactor 9 A.

1 . A chemical heat storage device that heats a heating target provided in a piping, the chemical heat storage device comprising:
 a reactor that contains reaction materials that generate heat by chemical reaction with a reaction medium;   an adsorber that adsorbs the reaction medium with an adsorbent to store the reaction medium; and   a connection pipe that connects the adsorber and the reactor,   
       wherein the reactor is provided around an outer peripheral surface of a portion at which the heating target is provided in the piping, and includes a plurality of inlets through which the reaction medium is fed. 
     
     
         2 . The chemical heat storage device according to  claim 1 , wherein the reactor surrounds the entire outer peripheral surface of the portion at which the heating target is provided in the piping in a circumferential direction, and wherein the plurality of inlets are arranged so as to be at equal intervals in the circumferential direction of the reactor. 
     
     
         3 . The chemical heat storage device according to  claim 1 , wherein the plurality of inlets are arranged at a portion other than a lower portion of the reactor in a direction of gravitational force to prevent blockage of each of the inlets by the reaction material. 
     
     
         4 . The chemical heat storage device according to  claim 1 , wherein the reactor includes divided areas where the reaction medium is movable corresponding to the respective plurality of inlets, and wherein the inlet is provided in the respective divided areas. 
     
     
         5 . The chemical heat storage device according to  claim 1 , wherein the reactor includes an outlet for discharging the reaction medium, and wherein the outlet is arranged in a portion other than a lower portion of the reactor in a direction of gravitational force to prevent blockage of the outlet by the reaction material.
