Example Embodiment
[0025] Example 1
[0026] Such as figure 1 As shown, a chiller 1 for high-temperature crude syngas includes a gas flow channel 2 of the chiller 1 and an atomizing nozzle 3 installed on the side wall of the gas flow channel 2. The gas flow channel 2 is used to connect to a gasification furnace The reaction chamber 4 and the cooling chamber 5 provide a mixing space for the chilling medium and the high-temperature crude synthesis gas; the atomizing nozzle 3 can be a single-channel pressure nozzle 9 or a dual-channel gas-liquid two-phase nozzle 10, single-channel pressure type The structure of nozzle 9 or dual-channel gas-liquid two-phase nozzle 10 is as follows: image 3 , Figure 4 As shown, the single-channel pressure nozzle 9 used in this embodiment is evenly distributed on the side wall of the gas flow channel 2. The gas flow channel 2 can be a water-cooled wall 6 or a refractory and wear-resistant lining 7 or both Combination form, the shape is cylindrical or conical or a combi...
Example Embodiment
[0027] Example 2
[0028] The atomization nozzle 3 in Example 1 adopts a dual-channel gas-liquid two-phase nozzle 10, the chilled water inlet manifold 8 adds a gas-phase channel, the gas-phase channel takes compressed synthesis gas, and the central flow path of the gas-liquid two-phase nozzle 10 takes compressed synthesis gas. The annulus is chilled water. The chilled water is sheared and broken by a high-speed airflow, and sprayed into the gas flow channel 2 through atomization. The rest of the structure is the same as the first embodiment.
Example Embodiment
[0029] Example 3
[0030] A high-temperature crude synthesis gas quenching device, the quenching device is provided with a gas flow channel, an atomizing nozzle installed on the side wall of the gas flow channel, and the gas flow channel is used to connect the reaction chamber and the cooling chamber of the gasification furnace and provide stimulation The mixing space of cold medium and high-temperature crude synthesis gas. The atomizing nozzle is a dual-channel gas-liquid two-phase nozzle. One channel is a liquid-phase channel and the other channel is a gas-phase channel. The liquid phase is water, and the gas phase can be water vapor, Syngas or inert gas. The atomizing nozzles are evenly distributed on the side wall of the gas flow channel, and are used to evenly spray the quenching medium into the high-temperature crude synthesis gas to quench the high-temperature crude synthesis gas to a specific temperature range. The gas flow channel is composed of water-cooled walls and re...
