1. A Y-shaped entrained-flow high-temperature zoned gasification device adopting dry-process slag-discharging, comprising:
a Y-shaped entrained-flow gasifier, wherein the Y-shaped entrained-flow gasifier is partitioned by a sectioned conical head into a gasification chamber and a chilling chamber;
a descending bed atomizing chiller arranged in the chilling chamber;
a conical top of the descending bed atomizing chiller in communication with an outlet of the sectioned conical head;
two or more chilling atomizing nozzles are evenly arranged on the conical top of the descending bed atomizing chiller in a circumferential direction;
a main nozzle is arranged at a top of the gasification chamber;
three or more side nozzles are arranged evenly on an upper side wall of the gasification chamber in the circumferential direction, wherein a first angle between the side nozzle and a horizontal direction is −15°-15°, a second angle between the side nozzle and a radial direction is 2°-35°, and the side nozzles are configured to form swirls in the gasification chamber; and
a conical fluidized bed heat exchange slag discharger is arranged at a bottom of the chilling chamber and connected with a plurality of fluidized gas nozzles and a lock hopper, wherein the fluidized gas nozzles are distributed on a lower wall of the discharger and the lock hopper is configured for variable pressure slag discharging;
wherein:
an upper part of the chilling chamber connected with a raw synthesis gas outlet pipe,
the raw synthesis gas outlet pipe is connected to an inlet of a fire-tube convection waste boiler,
a respective outlet of the fire-tube convection waste boiler is connected to a respective inlet of a gas-solid separator,
a respective outlet of the gas-solid separator is connected to a respective inlet of a carbon scrubber, a top outlet of the carbon scrubber is connected with a synthesis gas discharge pipe, and
a bottom outlet of the carbon scrubber is connected with a black water discharge pipe, and the black water discharge pipe is connected to the chilling atomizing nozzles.
