Abstract

The utility model discloses a waste heat utilization system of a calcination furnace. The waste heat utilization system comprises a calcination furnace main chimney flue and a heat transfer clamping sleeve arranged on the calcination furnace main chimney flue, wherein the two ends of the heat transfer clamping sleeve are respectively provided with a media inlet pipe and a media outlet pipe, and the media outlet pipe is connected with a media storage tank; a heat energy of a high-temperature gas is reused, the loss of the heat energy and the waste of an energy source are reduced, and the energy utilization rate is improved; meanwhile, the temperature of the discharge tail gas is reduced, the environmental pollution is reduced, the energy conservation and emission reduction are realized, the exterior of the heat transfer clamping is provided with an insulating layer, the heat loss is effectively reduced, and the heat transfer efficiency is improved; the calcination furnace main chimney flue is provided with an auxiliary calcination furnace flue, the inlet and outlet of the calcination furnace subsidiary flue are positioned on the two ends of the heat transfer clamping sleeve, and a fault valve is arranged between the inlet of the auxiliary calcination furnace flue and the heat transfer sleeve; and when the heat transfer clamping sleeve is in malfunction, the failure valve is closed, the high-temperature gas is exhausted through the calcination furnace subsidiary flue, the maintenance and service of the hot water clamping sleeve is convenient, and the control is simple.

Description

A kind of calcining furnace bootstrap system
Technical field
The utility model belongs to charcoal element manufacturing waste heat utilization equipment technical field, particularly a kind of calcining furnace bootstrap system.
Background technology
At present, all there is calcining furnace in the enterprise of domestic production charcoal element, the calcining furnace power consumption is very huge, the calcining furnace internal temperature is up to more than 2600 ℃ in calcination process, calcining furnace top will produce the high-temperature gas about 1100 ℃, these high-temperature gases are discharged by chimney, and take away a large amount of heat energy, and heat-energy losses is serious.This part heat-energy losses accounts for about 30% of calcination process total amount of heat, causes great energy waste; Simultaneously, high-temperature gas has caused severe contamination to atmospheric environment, makes environment, weather severe exacerbation.
The utility model content
The purpose of this utility model provides the low calcining furnace bootstrap system of a kind of energy savings, energy utilization rate height and environmental pollution.
For achieving the above object, the technical solution of the utility model is: a kind of calcining furnace bootstrap system, comprise the heat exchange jacket that arranges on calcining furnace flue collector and the calcining furnace flue collector, the heat exchange jacket two ends are respectively equipped with the medium inlet pipe and medium goes out pipe, and the medium inlet pipe links to each other with the medium holding vessel.
Described heat exchange jacket outside is provided with heat-insulation layer.
Described calcining furnace flue collector is provided with the auxiliary flue of calcining furnace, and the auxiliary flue of calcining furnace is imported and exported and is positioned at the heat exchange jacket two ends, is provided with the fault valve between the auxiliary chimney intake of calcining furnace and heat exchange jacket.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises the heat exchange jacket that arranges on calcining furnace flue collector and the calcining furnace flue collector, the heat exchange jacket two ends are respectively equipped with the medium inlet pipe and medium goes out pipe, the medium inlet pipe links to each other with the medium holding vessel, heat energy to high-temperature gas recycles, can reduce heat-energy losses and energy waste, improve energy utilization rate; Simultaneously, reduce the temperature of institute's emission, environmental contamination reduction is realized energy-saving and emission-reduction.
2, be provided with heat-insulation layer in the heat exchange jacket outside, can effectively reduce heat loss, improve heat exchange efficiency.
3, be provided with the auxiliary flue of calcining furnace at the calcining furnace flue collector, the import and export of the auxiliary flue of calcining furnace are positioned at the heat exchange jacket two ends, between the import of the auxiliary flue of calcining furnace and heat exchange jacket, be provided with the fault valve, when heat exchange jacket breaks down, the closing fault valve, make high-temperature gas pass through the auxiliary flue of calcining furnace and discharge, be convenient to hot water jacket's Maintenance and Repair, control easy.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Calcining furnace bootstrap system as shown in Figure 1, it comprises the heat exchange jacket 4 that arranges on calcining furnace flue collector 1 and the calcining furnace flue collector 1, the two ends, the left and right sides of heat exchange jacket 4 are respectively equipped with medium inlet pipe 6 and medium goes out pipe 7, and medium inlet pipe 6 ends are communicated with medium holding vessel 8.In order to reduce thermal loss, be provided with heat-insulation layer 5 in heat exchange jacket 4 outsides.For the ease of control, be provided with the auxiliary flue 2 of calcining furnace at calcining furnace flue collector 1, the import and export of the auxiliary flue 2 of calcining furnace are positioned at heat exchange jacket 4 two ends, are provided with fault valve 3 between the import of the auxiliary flue 2 of calcining furnace and heat exchange jacket 4.When heat exchange jacket 4 broke down, closing fault valve 3 made high-temperature gas pass through the auxiliary flue 2 of calcining furnace and discharges, and is convenient to hot water jacket 4 Maintenance and Repair.
Operation principle of the present utility model is: the heat that absorbs calcining furnace flue collector 1 interior high-temperature gas by the heat exchanging water-jacket's 4 that flows through heat transferring medium, heat exchange medium temperature raises, can be used for boiler heating cold water after the output of high temperature heat transferring medium, can be used for heating behind the cool water heating, perhaps cool water heating is become to have the superheated steam of certain pressure, then utilize superheated steam by steam turbine and with the alternator generation of its interlock.
