Detailed Description
The following describes in detail embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the traditional glass production process, a kiln plays an important role in melting raw materials and providing high-quality glass liquid for the next procedure. During the dissolving process, a large amount of high-temperature flue gas is generated, and the flue gas needs to be cooled and filtered by a flue and then is discharged into the atmosphere. However, the temperature of the flue gas just entering the flue is very high (about 1200 ℃), which causes the flue gas to burn out at the outlet of the kiln flue, thereby seriously affecting the service life of the flue and easily causing dust deposition and blockage at the outlet.
In order to solve the above-described problems, the present invention provides the following cooling device.
As shown in fig. 1, the cooling device for cooling a flue of a kiln of the present invention includes a connecting pipe 100 and a cooling pipe 200; one end of the connecting pipe 100 is used for communicating with the flue body 300, and the other end is a flue gas inlet 110; the cooling pipe 200 is disposed around the connection pipe 100 along the circumferential direction of the connection pipe 100, and one end of the cooling pipe 200 is a cooling fluid inlet and the other end is a cooling fluid outlet.
Because the cooling device of the utility model is communicated with the flue body 300 through one end of the connecting pipe 100, the flue gas inlet 110 of the connecting pipe 100 is used for receiving high-temperature flue gas, and the cooling pipe 200 is arranged around the connecting pipe 100 along the circumferential direction of the connecting pipe 100 to cool the flue gas in the connecting pipe 100, compared with the prior art, the cooling device can effectively prevent the high-temperature flue gas from directly contacting with the flue body 300, and the cooled flue gas enters the flue body 300, thereby effectively ensuring the service life of the flue body 300 and preventing the occurrence of dust accumulation and blockage.
It should be understood that the cooling pipe 200 is disposed around the connection pipe 100 along the circumference of the connection pipe 100 to improve the cooling effect on the flue gas flowing through the connection pipe 100, for example, the cooling pipe 200 may include a plurality of cooling branch pipes, each of which is annular, and the plurality of cooling branch pipes are spaced along the length direction of the connection pipe 100. In order to reduce the production cost and facilitate the control of the flow of the cooling liquid in the cooling pipe 200, in one embodiment of the present invention, the cooling pipe 200 has a spiral structure, and the spiral cooling pipe 200 can sufficiently cool the flue gas.
It should be understood that the cooling pipe 200 may be disposed inside or outside the connection pipe 100, and when the cooling pipe 200 is disposed inside the connection pipe 100, the cooling pipe 200 is directly contacted with the high-temperature flue gas, and the cooling effect is better. When the cooling pipe 200 is sleeved on the outer side wall of the connection pipe 100, the cooling pipe 200 can indirectly provide cooling for the high-temperature flue gas on the one hand, and can also effectively prevent the adverse effect of the high-temperature flue gas on the service life of the high-temperature flue gas on the other hand.
Further, in order to prevent the problem of rusting in the working environment of high-temperature flue gas, in one embodiment of the present invention, the cooling pipe 200 is a copper pipe.
In order to make the high temperature flue gas flow into the connection pipe 100 more smoothly, in an embodiment of the present invention, as shown in fig. 1, the diameter of the flue gas inlet 110 is larger than that of the connection pipe 100, and preferably, the flue gas inlet 110 may also be provided in a bell mouth shape, an open portion of which faces into the furnace chamber of the furnace, so that the flue gas is received more conveniently.
Further, in an embodiment of the present invention, the cooling device includes a thermostat configured to detect the temperature of the cooling liquid in the cooling pipe 200 and adjust the flow rate and/or temperature of the cooling liquid, so as to achieve the purpose of accurately cooling the cooling liquid by controlling the flow rate and/or temperature of the cooling liquid.
Specifically, the cooling device may include a flow regulating valve installed in the cooling pipe 200, and a temperature controller electrically connected to the flow regulating valve to be able to control the operation of the flow regulating valve.
In the above embodiment, a reference temperature may be set in the controller in advance, when the temperature sensor of the thermostat detects that the temperature of the cooling liquid in the cooling pipe 200 is lower than the reference temperature, the flow rate of the cooling liquid in the cooling pipe 200 is reduced by operating the flow rate adjusting valve through the controller, and when the temperature sensor detects that the temperature of the cooling liquid in the cooling pipe 200 is higher than the reference temperature, the flow rate of the cooling liquid in the cooling pipe 200 is increased by operating the flow rate adjusting valve through the controller, so as to achieve the purpose of accurately reducing the temperature.
In addition, the cooling device may further include a cooler for cooling the coolant, and the thermostat is electrically connected to the cooler to be able to control an operation of the cooler.
In the above embodiment, a reference temperature may be set in the controller in advance, when the temperature sensor of the thermostat detects that the temperature of the cooling liquid in the cooling pipe 200 is lower than the reference temperature, the controller operates the cooler to decrease power to increase the temperature of the cooling liquid in the cooling pipe 200, and when the temperature sensor detects that the temperature of the cooling liquid in the cooling pipe 200 is higher than the reference temperature, the controller operates the cooler to increase power to decrease the temperature of the cooling liquid in the cooling pipe 200, thereby achieving the purpose of accurately decreasing the temperature.
When the temperature lowering device is simultaneously provided with the flow rate adjusting valve and the cooler, when the temperature sensor of the temperature controller detects that the temperature of the cooling liquid in the cooling pipe 200 is lower than the reference temperature, the flow rate adjusting valve and the cooler are simultaneously operated by the controller to raise the temperature of the cooling liquid in the cooling pipe 200, and when the temperature sensor detects that the temperature of the cooling liquid in the cooling pipe 200 is higher than the reference temperature, the flow rate adjusting valve and the cooler are simultaneously operated by the controller to lower the temperature of the cooling liquid in the cooling pipe 200, so that the purpose of accurately lowering the temperature is achieved.
In order to utilize the cooling fluid efficiently and save energy costs, in one embodiment of the present invention, the cooling pipe 200 and the cooler constitute a circulation loop.
The utility model also provides a flue structure, which comprises a flue body 300 and the cooling device, wherein one end of the connecting pipe 100 of the cooling device is communicated with the flue body 300.
The utility model also provides a kiln which comprises the flue structure.
