Embodiment 1

[0018] Example 1: Such as figure 1 As shown, the present invention includes: a water inlet pipe 1, a diffuser pipe 2, a tank body 3, a flushing table 4, a detachable sealing plate 5, a water outlet pipe 6-1, 6-2, and the water inlet pipe 1 is arranged on the tank body 3. The top of the water inlet pipe 1 is connected to the upper end of the trapezoidal cone-shaped diffuser 2, the lower end of the diffuser 2 is connected to the tank 3, the lower end of the tank 3 is provided with a flushing table 4, in the tank 3 Water outlet pipes 6-1 and 6-2 are arranged above the outer side walls. The high-temperature and high-pressure gray water enters the tank through the inlet pipe 1 and the angle valve, and the three-phase fluid of gas, liquid and solid of the gray water buffered by pressure relief flows out through the outlet pipes 6-1 and 6-2, and directly enters the subsequent flash evaporation unit. Due to the adoption of the high-pressure flash evaporation pressure relief buffer dev...

Embodiment 2

[0019] Example 2: The difference from Example 1 is that figure 1 As shown, the present invention also includes a flushing station 4 provided at the bottom of the tank 3, the flushing station 4 is located on the detachable sealing plate 5, and the detachable sealing plate 5 is fixed to the tank 3 by bolts. bottom of. Easy to replace.

Embodiment 3

[0020] Example 3: The difference from Example 1 is that figure 1 As shown, the flushing table 4 is made of 150mm-250mm high chromium cast iron or ceramic material. A high chromium cast iron or ceramic scouring table 4 is set at the bottom of the tank body 3 to receive strong erosion from the high temperature and high pressure gray water from the top of the tank body, which has a better buffer effect.

Abstract

The invention discloses a coal gasification chilling grey water high pressure flashing decompression buffering device. A water inlet pipe and a diffusing pipe are arranged on the top portion of the coal gasification chilling grey water high pressure flashing decompression buffering device; a water outlet pipe is arranged on the side portion of the coal gasification chilling grey water high pressure flashing decompression buffering device; abrasion resistant silicon carbon or lining ceramic materials are spray coated on the inner wall of the coal gasification chilling grey water high pressure flashing decompression buffering device; a high chromium cast iron or ceramic plate washing table is arranged on the bottom of the coal gasification chilling grey water high pressure flashing decompression buffering device, and the washing platform is detachable component which can be replaced according to conditions; high temperature and pressure grey water enters from an angle valve and the diffusing pipe from the top portion of a tank body, and the grey water through compression and buffering flows out from the water outlet pipe arranged on the side portion of a compression buffering device and enters a flash column. The coal gasification chilling grey water high pressure flashing decompression buffering device is simple in structure, low in investment cost, and simple and convenient to maintain and replace, can effectively solve the problem that chilling high solid content grey water erodes the flash column and the angle valve, and ensures long-period operation of a system.

Description

Technical field [0001] The invention relates to a coal gasification chilled ash water high pressure flash evaporation pressure relief buffer device, which is suitable for the ash water treatment process of dry coal powder pressurized gasification and coal water slurry pressurized gasification. High temperature and high pressure chilling ash water vapor, liquid and solid three-phase pressure relief and buffer in front of the flash tower. Background technique [0002] The gasification of coal to obtain clean fuels or other primary chemical products has broad prospects in my country. In order to achieve the goal of energy saving and emission reduction, the gray water produced by the gasifier needs to be energy recovered and recycled. [0003] Coal pressurized gasification is the incomplete combustion reaction of coal and oxygen or oxygen-enriched gas under pressure and high temperature to produce high-temperature synthesis gas. The high-temperature gas is cooled by direct contact with...
