Description
Technical field
This utility model relates to a kind of waste heat utilization device, especially kiln tail gas waste heat utilizing device.
Background technology
There is sintering process in ceramic tile production process, it sends substantial amounts of heat by kiln metabolic water coal gas, but simultaneously substantial amounts of heat is discharged in air by air vent along with waste gas again, and air inlet needs to suck substantial amounts of cold air, there is the huge temperature difference between intake air temperature and delivery temperature thus causing that heat losses is too much, dropping low-energy utilization ratio.
Utility model content
The purpose of this utility model is in that to provide one can effectively utilize waste heat in kiln burning waste gas that inlet air is heated, and improves the device of heat Lee Yongxin efficiency.
A kind of kiln tail gas waste heat utilizing device, including kiln, aerator, aerator air inlet pipe, kiln exhaust gases pipe, kiln air inlet pipe, kiln water gas pipe, fan inlet is connected with aerator air inlet pipe, aerator gas outlet is connected with kiln air inlet pipe, kiln exhaust gases mouth is connected with kiln exhaust gases pipe, kiln is connected with kiln water gas pipe, described aerator air inlet pipe is provided with heat-exchange device, described heat-exchange device includes air inlet, gas outlet, exhaust gas entrance and waste gas outlet, aerator air inlet pipe is connected with heat-exchange device gas outlet, kiln exhaust gases pipe is connected with the exhaust gas entrance of heat-exchange device, the air inlet of heat-exchange device and waste gas outlet are all and atmosphere.
The interior parallel distribution of described heat-exchange device has some airways.
Described aerator air inlet pipe, kiln air inlet pipe and kiln exhaust gases pipe and heat-exchange device outer surface are all enclosed with insulation material, prevent the heat losses in pipeline and parts by arranging insulation material, improve heat utilization efficiency.
The length of described heat-exchange device is 5 ~ 10 times of its diameter.
Described heat-exchange device can in parallel or series or be used alone.
The beneficial effects of the utility model are in that, by arranging heat-exchange device, are recycled by the waste heat in kiln waste gas, heated under the effect of aerator by air with it, hot-air is blasted kiln, it is ensured that heat losses reduces, and improve heat utilization efficiency.

In figure: 1 kiln, 2 aerators, 3 heat-exchange devices, 31 heat-exchange device air inlets, 32 heat-exchange device gas outlets, 33 heat-exchange device waste gas outlets, 34 heat-exchange device exhaust gas entrances.
Detailed description of the invention
A kind of kiln tail gas waste heat utilizing device, such as Fig. 1 ~ 2, including kiln, aerator, aerator air inlet pipe, kiln exhaust gases pipe, kiln air inlet pipe, kiln water gas pipe, fan inlet is connected with aerator air inlet pipe, aerator gas outlet is connected with kiln air inlet pipe, kiln exhaust gases mouth is connected with kiln exhaust gases pipe, kiln is connected with kiln water gas pipe, described aerator air inlet pipe is provided with heat-exchange device, described heat-exchange device includes air inlet, gas outlet, exhaust gas entrance and waste gas outlet, aerator air inlet pipe is connected with heat-exchange device gas outlet, kiln exhaust gases pipe is connected with the exhaust gas entrance of heat-exchange device, the air inlet of heat-exchange device and waste gas outlet are all and atmosphere.
The interior parallel distribution of described heat-exchange device has some airways.
Described aerator air inlet pipe, kiln air inlet pipe and kiln exhaust gases pipe and heat-exchange device outer surface are all enclosed with insulation material, prevent the heat losses in pipeline and parts by arranging insulation material, improve heat utilization efficiency.
The length of described heat-exchange device is 5 ~ 10 times of its diameter.
Described heat-exchange device can in parallel or series or be used alone.
Its principle is: containing huge heat in the tail gas that kiln is discharged, and kiln operationally needs to be supplied air by aerator endlessly, and the air themperature in air is room temperature, being blown in kiln needs to absorb many heats, the used heat in kiln tail gas is adopted to be heated by the air being blown in kiln, thus reducing the heat that air absorbs, so circulate, it is ensured that the EGT discharged from heat-exchange device is relatively low.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content thereof to make or equivalence transformation; or directly or indirectly use other association areas beyond this utility model, all can be considered in scope of patent protection of the present utility model.
