The invention discloses a high-temperature reverse blowing process. The high-temperature reverse blowing process comprises the following steps: a, introducing reverse blowing air which is heated to the specified temperature into a sealed chamber; b, stopping introducing the reverse blowing air into the sealed chamber by a high-temperature valve when detecting the pressure in the sealed chamber reaches the set threshold; c, controlling the reverse blowing air which reaches the set pressure to be output by other high-temperature valves and reversely blowing a target to be reversely blown; and d, controlling and stopping reverse blowing by a high-temperature valve at an air outlet of the sealed chamber after the reverse blowing process is finished, controlling the reverse blowing air heated to the specified temperature at an air inlet of the sealed chamber to enter the sealed chamber again, and circulating to finish a next reverse blowing process. The invention also discloses a reverse blowing device for the high-temperature reverse blowing process; the reverse blowing device can be used under the high-temperature condition and is excellent in dust removal effect.

The invention discloses a synthesis method of a water-soluble triene cross-linking agent. The synthesis method comprises the following steps: adding triaminopropylamine (trpn), water and cationic surfactant into a reactor, evenly stirring and mixing, controlling the reaction temperature in a range of 30 to 35 DEG C, dropwise adding chloropropene into the reactor within 4 hours, controlling the temperature under 35 DEG C, and keeping on stirring until the solution turns transparent after the adding of chloropropene so as to obtain the triene cross-linking agent. The invention also provides a synthesis method of a high-temperature resistant water-absorbing resin by using the triene cross-linking agent. The synthesis method comprises the following steps: adding a mixed solution of copolymerization monomers and the triene cross-linking agent into a reactor, introducing nitrogen gas for 30 minutes, then adding an initiator, stopping introducing nitrogen gas after 10 minutes, carrying out reactions for 4 hours at a room temperature so as to obtain a reaction product, subjecting the reaction product to an extruding and granulating process, drying the granules at a temperature of 80 DEG C, and finally grinding the dried granules so as to obtain the high-temperature resistant water-absorbing resin. The synthesis method of water-absorbing resin has the advantages of simple process and low energy consumption, the saturated water absorption rate of the resin in distilled water with a temperature of 300 DEG C is 150 to 400 g / g, and the saturated water absorption rate of the resin in a NaCl water solution with a mass percentage of 0.9% is 50 to 130 g / g.
