Description

Technical Field

[0001] The utility model relates to the technical field of surface coolers, in particular to a novel waste heat recovery device for a surface cooler of a fume furnace. Background Art

[0002] Surface cooler: The principle is to let the heat medium or coolant or refrigerant flow through the inner cavity of the metal pipe, and the air to be treated flows through the outer wall of the metal pipe for heat exchange to achieve the purpose of heating or cooling the air. The heat and moisture exchange of the surface cooler is carried out under the action of the temperature difference and water vapor partial pressure difference between the main air and the boundary layer air close to the outer surface of the heat exchanger.

[0003] The existing patent CN206638031U proposes a new type of fumigation furnace. The utility model includes a furnace body, a smoke exhaust pipe is arranged on the top of the furnace body, and a primary and secondary air supply pipe group and a discharge port are arranged at the lower part of the furnace body, a feed port is arranged at the middle and upper part of the furnace body, and a tertiary air supply pipe is arranged at the upper part of the furnace body, and the tertiary air supply pipe is located between the feed port and the top of the furnace body, and an accident slag discharge port is arranged below the discharge port, and an anti-blocking device is arranged on the primary and secondary air supply pipe group. The utility model arranges a tertiary air supply pipe at the upper part of the furnace body, so that the raw materials are mixed more fully in the furnace body, the speed of smelting is accelerated, and the smelting effect is improved. When the furnace body encounters a sudden stop of air, the primary and secondary air has no pressure, and the slag in the furnace is backflowed into the primary and secondary air ports, resulting in a dead furnace accident, the anti-blocking device is started to blow compressed gas into the furnace body, and the discharge port and the accident slag discharge port are all opened, and the slag in the furnace body is quickly discharged, reducing the slag processing and removal time, which is conducive to improving the operation rate and production efficiency of the fumigation furnace.

[0004] However, although the existing patent CN206638031U improves the smelting effect, when the air inside the furnace body suddenly stops and the primary and secondary air have no pressure, the slag in the furnace flows back into the primary and secondary air ports, causing a furnace death accident, the anti-blocking device is started to blow compressed gas into the furnace body, and the discharge port and the accident slag discharge port are all opened to quickly discharge the slag in the furnace body, reducing the slag processing and removal time, which is beneficial to improving the operation rate and production efficiency of the fuming furnace, but when the equipment works for a long time, it may generate greater energy consumption.
