Detailed Description
The utility model is described in further detail below with reference to the drawings and the detailed description.
Referring to fig. 3 to 5, the present embodiment provides an apparatus 100 for heating water by using heat of a kiln tail, which includes a kiln tail cooling section 1 and a heating water pipe 2.
In this embodiment, heating water pipes 2 are respectively laid on the upper layer and the lower layer of the kiln tail cooling section 1, and referring to fig. 2 and 3, the heating water pipes 2 are respectively installed on the upper layer and the lower layer of the kiln tail cooling section 1 in a horizontal arrangement manner, and a cold water inlet 6 and a hot water outlet 7 are respectively installed at the left end and the right end of the heating water pipe 2.

When the ceramic tiles 4 in the kiln tail cooling section 1 are conveyed outwards through the conveying roller bars 3, cold water flowing in the heating water pipe 2 exchanges heat with the ceramic tiles 4 on the conveying roller bars 3, so that heat carried by the ceramic tiles 4 is partially transferred into the cold water in the heating water pipe 2, the cold water is heated, and the heated hot water can be used as a high-quality heat source, for example, domestic water, water during ball milling, mud and the like.
In some embodiments, in order to be able to exchange heat sufficiently with the tiles 4, the flow direction of the cold water in the heating water pipe 2 is set opposite to the conveying direction of the tiles 4, namely, the closer to the kiln tail, the lower the temperature of the tiles 4, the end is used as a cold water inlet 6, so that the water flow direction is opposite to the moving direction of the tiles 4, and the water temperature is also increased gradually. Cold water is introduced into the heating water pipe 2 and continuously flows, and the temperature thereof is heated and gradually rises to the highest temperature and extends out from the interior of the kiln.
Referring to fig. 4, in order to cope with the situation that the highest temperature of the heated cold water does not meet the use requirement and needs to exchange heat again, in some embodiments, the device 100 for heating water by using kiln tail heat further comprises a circulating heating pipe 5, one end of the circulating heating pipe 5 is connected between the cold water inlet 6 and the heating pipe, and the other end of the circulating heating pipe 5 is connected between the hot water outlet 7 and the heating pipe, so that when the highest temperature of the heated cold water does not meet the use requirement, the heated cold water can not flow out from the hot water outlet 7, but returns to one side of the cold water inlet 6 through the circulating heating pipe 5, and enters the heating water pipe 2 again through the cold water inlet 6 to exchange heat with the ceramic tile 4, and after the required use temperature is reached, the heated hot water flows out through the hot water outlet 7. It will be appreciated that in order to be able to control the closing and opening of the cold water inlet 6 and the hot water outlet 7, a first valve 9 and a second valve 10 are respectively installed at the cold water inlet 6 and the hot water outlet 7.
Similarly, in order to cope with the situation that the temperature of the heated hot water is higher than the use requirement, the device 100 for heating water by using the heat of the kiln tail further comprises a temperature-adjusting cold water supply pipe 8, wherein one end of the temperature-adjusting cold water supply pipe 8 is connected to the hot water outlet 7 and is located at the upstream of the second valve 10, so as to inject cold water for adjusting the temperature of the discharged water into the hot water outlet 7.
It will be appreciated that a temperature sensor may be installed at the hot water outlet 7 of the heating water pipe 2, through which the temperature of the hot water is sensed, as to whether the heated hot water temperature has reached the use requirement. And (3) measuring whether the water temperature exceeds a required value, if the water temperature exceeds the required value, introducing cold water through a temperature-regulating cold water supply pipe 8 to cool the water to a set temperature, and if the temperature cannot meet the use requirement, entering the next circulation heating through a circulation heating pipe 5 until the temperature reaches the use requirement.
To sum up, in the kiln tail cooling section 1 of the embodiment, the heating water pipes 2 are installed, the heating water pipes 2 are arranged along the length direction of the kiln, cold water flows from one low-temperature end to the upper side Wen Yiduan, and the flowing direction of the water flow is opposite to the moving direction of the ceramic tile 4, so that heat exchange between the ceramic tile 4 and the water is facilitated. Cold water enters the tail cooling section box body from the low temperature section and then flows out from the high temperature section through the heating water pipe 2 after being heated, if the temperature reaches a set value, the cold water can be directly used as a high-quality heat source, and if the temperature can not reach a specified temperature, the cold water can enter the circulation for reheating or can be added into part of the cold water until the water temperature reaches the set temperature. The brick outlet temperature of the kiln is effectively reduced through the implementation of the system, the working environment of the kiln tail is improved, and meanwhile, more heat carried by ceramic products is exchanged out to be used as a useful heat source, so that the heat can be recycled, the production energy consumption is saved, and certain economic benefits are achieved.
