[0026] use Image 6 The process shown is a chemical heat pump cycle of hydrogenation / dehydrogenation, which is used to complete the recovery and utilization of low-temperature industrial waste heat at 60-100 °C in a factory in Xi'an. The process uses two pairs of ring-disk chemical heat pump reactors, among which the reactors R-11 and R-21 are filled with metal hydride (Metal hydride, referred to as MH) reactant MH 1 , reactors R-12 and R-22 are filled with MH 2 . R-11 and R-12, R-21 and R-22 are respectively connected with hydrogen pipelines. T H , T M , T L are high-, medium-, and low-temperature heat sources, respectively, S H , S M , S L are the heat absorbed / released at high temperature, medium temperature and low temperature, respectively.
[0027] Taking low-temperature industrial waste heat at 60-100°C as the heat source and a chemical heat pump with a thermal output power of 10kW as an example, if paired ring-disk chemical heat pump reactors are used to compl...

The invention discloses a circular disc chemical heat pump reactor, comprising a casing, vertically or horizontally arranged, there are head closing pipe boxes for air inlet and outlet at two ends of the casing, respectively, where the air inlet and outlet are connected with the casing into an organic whole; there are heat exchanging fluid outlet and inlet respectively arranged on and under the casing, there are a plurality of air pipes uniformly arranged in the casing, a plurality of groups of pairing circles and discs are arranged at regular intervals apart from the air pipes to fill solid reactant. The axial junctions of circles and discs with the air pipes are made with a plurality of open holes, and a filter screen outside the open holes prevents the solid powder from entering in the hydrogen pipe; simultaneously, a plurality of groups of isolation plates are arranged in the circular discs for strengthening heat and matter transmitting effect. The invention has the characters in large amount of filled reactant, high heat transmitting efficiency, good heat and matter transmitting effect, compact structure, regulating and control convenience, etc.
Description
technical field [0001] The invention relates to a gas-solid phase reactor for chemical heat pump, heat exchange and refrigeration, which belongs to the overall reaction and heat exchange scheme of a chemical heat pump reactor for gas-solid reactions such as hydrogenation / dehydrogenation, and particularly relates to a ring-disk chemical reactor. Heat pump reactor. Background technique [0002] The gas-solid reactors currently used in chemical heat pumps mainly include the following categories: [0003] Tubular Reactor - There are two types of filling inside the tube and loading outside the tube. The gas-solid reactor outside the tube is equipped with solid reactants on the shell side of the heat exchange tube. The filling capacity is large, but the heat exchange efficiency is extremely low and the large-sized outer filter tube cannot be processed at this stage, and the large-scale application of chemical heat pumps cannot be realized at present. , a...
