Problems solved by technology

In the past, the exhaust port of the heating furnace was directly connected to the outside of the furnace, and the heat with high calorific value contained in the flue gas and part of the water vapor generated in the furnace was directly discharged into the atmosphere, and a large amount of valuable energy was lost. At the same time, the direct emission of smoke to the atmosphere will also cause smoke pollution

Embodiment Construction

[0030] The present invention is described in detail below in conjunction with accompanying drawing.

[0031] As shown in the figure, the present invention provides a method of reverse heating in an intermittent temperature zone at atmospheric pressure, which is characterized in that it includes the following steps:

[0032] ① Input the hot liquid (or steam) into the heating coil (11) in the intermittent temperature zone of the heating device box (12) through the pipeline (6);

[0033] ② Pass the high-temperature flue gas after combustion through the flue (4), and reversely input it into the heat radiation coil (10) in the box (12) of the heating device;

[0034] ③Under normal pressure, the flue gas mixes with the heat transfer medium (13) in the heating device box (12) to heat the hot liquid (or steam).

[0035] The discontinuous temperature zone refers to that the heating device is connected in series by multiple casings (12), and the adjacent two-stage heating device casing...

Abstract

The invention relates to a reverse heating method of an intermittent temperature zone at normal pressure and a device thereof, especially aiming at a heating device for recovering waste heat in heating furnaces for comprehensive utilization. The invention combines such devices as the heating device, a flue gas cyclic heating circuit, a hydrothermal water (or steam) cyclic heating circuit, a control system and the like, and has the effects that the more the divided zones are, the higher the generated heat efficiency is, the invention reduces once emission of flue gas and pollution and is beneficial for environmental protection, meanwhile, the device has no pressure and does not belong to boilers and pressure vessels, thus having no risks.

Description

1. Technical field [0001] The invention relates to a reverse heating method at normal pressure in an intermittent temperature zone, in particular to a heating device for comprehensive utilization of waste heat recovery of a heating furnace. 2. Background technology [0002] According to the current domestic heating furnaces with different structures, the exhaust gas temperature is high, and the temperature of the flue gas discharged from the exhaust port is approximately 250°C-375°C. In the past, the exhaust port of the heating furnace was directly connected to the outside of the furnace, and the heat with high calorific value contained in the flue gas and part of the water vapor generated in the furnace was directly discharged into the atmosphere, and a large amount of valuable energy was lost. At the same time, the direct emission of smoke to the atmosphere will also cause smoke pollution. In order to solve the reuse of high-temperature flue gas waste heat, reduce the exh...
