Embodiment

[0042] refer to figure 1 , a device for preventing the loss of filter sand when the HyCO process is backwashed with an iron-removing manganese tank, comprising an iron-removing manganese tank 1 filled with iron-removing manganese filter sand 11, and above the iron-manganese tank 1 It is the inlet, and the bottom is the outlet. The inlet is connected to the water inlet pipe 12 and the air inlet pipe 15. The water inlet pipe 12 and the air inlet pipe 15 meet to form a section of inlet pipe 18 near the inlet. The inlet pipe 18 is provided with a feed control valve V1, and the outlet Connect the outlet pipe 13 and the drain pipe 16, the outlet pipe 13 and the drain pipe 16 merge into a section of the outlet pipeline 19 near the outlet, and the backwashing water replenishment pipe 14 connected to the outlet pipeline 19 is led out from the inlet pipe 12. The outlet pipeline 19 is provided with a backwash water inlet valve V8, and the inlet is also connected to an exhaust pipe 17, an...

Abstract

The invention relates to a device and method to prevent loss of filter sand upon backflushing of an iron-manganese removal tank for HyCO process. The device comprises an iron-manganese removal tank filled with iron-manganese removal filter sand; the top of the iron-manganese removal tank is provided with a feed port, and the bottom thereof is provided with a discharge port; the feed port is connected with an inflow pipe and an intake pipe; the inflow pipe and the intake pipe join close to the feed port to form a feed port end pipeline which is provided with a feeding control valve; the discharge port is connected with an outflow pipe and a liquid discharge pipe; the outflow pipe and the liquid discharge pipe join close to the discharge port to form a discharge port end pipeline; a backflushing water supply pipe connected to the discharge port end pipeline is guided from the inflow pipe; the discharge port end pipeline is provided with a backflushing inflow valve; the feed port is alsoconnected with an exhaust pipe; the exhaust pipe is provided with an exhaust and backflushing common discharge valve. Compared with the prior art, the device and method have the advantages that the speed of water flow is controlled so that the loss of iron-manganese removal filter san is avoided; controlling is convenient, and normal use of the iron-manganese removal tank is unaffected.

Description

technical field [0001] The invention relates to a device and method for backwashing a manganese tank for removing iron, in particular to a device and method for preventing filter sand from being lost during backwashing of a tank for removing iron and manganese in a HyCO process. Background technique [0002] HyCO is hydrogen + carbon monoxide (Hydrogen+CO). In a narrow sense, HyCO is a chemical process that simultaneously produces hydrogen and carbon monoxide. Since carbon monoxide is usually produced simultaneously with hydrogen, HyCO is used in the gas industry to indicate a chemical production plant whose main product is hydrogen and / or carbon monoxide and / or a mixture of hydrogen and carbon monoxide (synthesis gas, or Syngas). or production process. [0003] The CO compressor and the circulating gas compressor are the main equipment of the HyCO separation device. After the gas is compressed, the temperature of the gas rises. In order to reduce the temperature, the gas ...
