Device for maintaining water level of smoke-impact water spinning type LNG (Liquefied Natural Gas) heating gasification furnace

Abstract

The invention relates to an improved device of a smoke-impact water spinning type LNG (Liquefied Natural Gas) heating gasification furnace and particularly relates to a device for maintaining a water level of the smoke-impact water spinning type LNG heating gasification furnace. An annular pipe ring (1) is horizontally arranged on the top of a vertical combustor jacket (7) which consists of an inner barrel and an outer barrel, and a plurality of water replenishing holes (1a) are formed in the peripheral wall of the annular pipe ring (1); and the annular pipe ring (1) is connected to a water tank (4) through a water inlet pipe (3), and a water supply power pump is arranged on the path of the water inlet pipe (3). The device disclosed by the invention has the advantages of ensuring to continuously replenish water into the heating gasification furnace, keeping the water level of a water pool in the heating gasification furnace to be stabilized in an optimal position, most fully developing the effects of smoke impact, splashing and entraining of water drops, water mist and water vapor, and ensuring the normal operation of the heating gasification furnace. The device disclosed by the invention is capable of effectively cooling the wall of a combustor to ensure that the wall of the combustor is not overheated, obtaining novel available functions except for ensuring and maintaining the working water level of the heating gasification furnace, ensuring the normal and safe operation of the smoke-impact water spinning type LNG heating gasification furnace, and improving the operation efficiency of the furnace.

Description

technical field [0001] The invention relates to an improved device for a flue gas impingement water cyclone type LNG heating gasifier, in particular to a device capable of maintaining the water level of the flue gas impingement water cyclone type LNG heating gasifier during operation. technical background [0002] Natural gas is a clean energy with high calorific value, low pollution of combustion products, and convenient storage and transportation. At a time when energy conservation and emission reduction have become a global consensus, natural gas has become one of the directions of energy development. In terms of transportation, natural gas is often transported by pipeline, such as my country's West-East Gas Pipeline, or condensed and liquefied natural gas into liquefied natural gas (LNG for short), which greatly reduces its volume (under normal pressure, 625M 3 Natural gas can be condensed into 1M 3 LNG), and then transported by ships, vehicles and other vehicles. For ...

Problems solved by technology

[0010] After the high-humidity flue gas flows through the coil to release heat, part of the water vapor in the flue gas condenses and drips back into the pool, and part of the water vapor is discharged out of the furnace with the flue gas, so the water in the pool continues to decrease. When the water level is lower than When the airflow swirls the disc of the water, the effect of the flue gas impacting, splashing, entraining water droplets, water mist, and water vapor is destroyed, which seriously affects the normal operation of the flue gas impacting the water-swirling LNG heating gasifier. Therefore, it is necessary to provide a A device that can maintain the water level of the flue gas impacting the water-swirling LNG heating gasifier, in order to maintain the normal operation of the heating gasifier
