Embodiment Construction

[0010] The present invention will be described in further detail below by way of examples.

[0011] A method for utilizing waste heat from flue gas of an organic carrier heating furnace, comprising the following steps: feeding the flue gas from an organic carrier heating furnace through the flue gas inlet 4 of a flue gas waste heat utilization device of the organic carrier heating furnace; Outlet 7 is discharged, and the material to be concentrated or dried is added from the feed port 2 at the same time, the waste heat of the flue gas of the organic carrier heating furnace preheats the material to be concentrated or dried, and the water vapor and other gases generated during the treatment are released from the Exhaust port 3 is discharged. When the treatment meets the requirements, the preheated material to be concentrated or dried is discharged from the discharge port 6. At the same time, the feed port 2 is continuously replenished with new materials to be processed.

Abstract

The invention discloses a method for utilizing the left heat of tail gas of organic carrier heating furnace, and relative device. It comprises: said tail gas is fed into the gas inlet (4) of smoke channel and discharged via the gas outlet (7), while the material that needing concentrated or dried is fed via the material inlet (2); the left heat of tail gas can preheat said material; the generated steam can be discharge via the gas outlet (3); when the treatment has reached demand, the material will be discharged via the material outlet (6); and the material inlet (2) will feed new materials. The invention can save energy and reduce cost, with simple structure and better heat exchange effect.

Description

technical field [0001] The invention relates to a method and a device for utilizing the residual heat of flue gas of an organic carrier heating furnace. Background technique [0002] At present, the flue gas of the organic carrier heating furnace is generally discharged directly into the atmosphere by the method of direct discharge, because the flue gas generally contains harmful substances or gases, so some methods or procedures for purifying the flue gas are used after treatment. , and then discharged into the atmosphere. Whether it is directly discharged or discharged after purification, the waste heat in the flue exhaust will be wasted in vain, which will cause a waste of energy. At the same time, a large amount of heat energy is required in the process of industrial concentration and drying. For example, the concentration of sodium nitrate solution now adopts the indirect steam heating method. Due to the high boiling point of sodium nitrate solution, it can reach 105 °...
