Description

Kiln chimney with cooling function

Technical Field

The utility model belongs to the technical field of support plate glass processing, specifically speaking especially relates to a kiln chimney with cooling function.

Background

In the process of combustion in a support plate glass kiln, high-temperature gas (about 300 ℃) is generated and discharged from a chimney, high-temperature smoke is discharged for a long time, so that an iron chimney is aged, oxidized and finally damaged, the chimney is replaced by stopping the machine, the working efficiency is reduced, a large amount of time and manpower and material resources are wasted, and in the prior art, devices for cooling the kiln chimney are rarely arranged.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome prior art not enough, provide a kiln chimney with cooling function, it can effectively reduce the speed that discharges high temperature flue gas and lead to chimney oxidation, ageing in the combustor working process, prolongs the life of chimney, has saved the cost.

In order to achieve the above purpose, the utility model is realized by adopting the following technical scheme:

the utility model provides a kiln chimney with cooling function, includes chimney and water tank, the lower extreme of chimney is equipped with the inlet tube, and the upper end is equipped with the outlet pipe, installs valve, water pump and thermometer on the inlet tube, installs the cooler on the outlet pipe, the lower extreme and the water piping connection of water tank, the upper end of water tank still with go out water piping connection.

Preferably, the chimney comprises an outer chimney and an inner chimney, the inner chimney is installed inside the outer chimney, a water circulation area is arranged between the inner chimney and the outer chimney, upper end faces of the outer chimney and the inner chimney are provided with upper sealing covers, and lower end faces of the outer chimney and the inner chimney are provided with lower sealing covers.

Preferably, the lower end of the water circulation area is communicated with the water inlet pipe, and the upper end of the water circulation area is communicated with the water outlet pipe.

Compared with the prior art, the beneficial effects of the utility model are that:

1. a water circulation area is formed between the outer chimney and the inner chimney, water is pumped into a water inlet at the lower end from the water tank by using a water pump, water is discharged from a water outlet at the upper end, and then enters the water tank for recycling, and the chimney in the high-temperature smoke environment is cooled by water circulation, so that the aging and oxidation time of the chimney is prolonged;

2. the thermometer is used for detecting the water temperature in the water tank and the water temperature entering the water circulation area, so that the temperature of the water in the water tank can be adjusted;

3. the water flowing out of the water circulation area can be cooled through the cooler so as to be recycled after entering the water tank;

4. waste condensate water in a factory can be adopted, the temperature of the condensate water is low, the cooling effect of a cooler can be omitted, and resources are saved;

to sum up, the utility model discloses can effectively reduce the speed that discharges high temperature flue gas and lead to chimney oxidation, ageing in the combustor working process, prolong the life of chimney, save the cost.

In the figure: 1. a chimney; 2. a water inlet pipe; 3. a valve; 4. a water pump; 5. a thermometer; 6. a water tank; 7. a water outlet pipe; 8. a cooler; 11. an outer chimney; 12. an inner chimney; 13. a lower sealing cover; 14. an upper sealing cover; 15. a water flow-through region.

Detailed Description

The present invention will be further described with reference to the following specific embodiments and the accompanying drawings.

Example 1:

as shown in fig. 1, a kiln chimney with cooling function, includes chimney 1 and water tank 6, the lower extreme of chimney 1 is equipped with inlet tube 2, and the upper end is equipped with outlet pipe 7, installs valve 3, water pump 4 and thermometer 5 on the inlet tube 2, installs cooler 8 on the outlet pipe 7, and the lower extreme and the inlet tube 2 of water tank 6 are connected, and the upper end of water tank 6 still is connected with outlet pipe 7. The low-temperature water flows through the chimney 1, so that the problem that the kiln chimney is easy to age and damage due to high-temperature smoke can be solved.

Example 2:

as shown in fig. 2 to 4, the kiln chimney 1 includes an outer chimney 11 and an inner chimney 12, the inner chimney 12 is installed inside the outer chimney 11, a water circulation area 15 is provided between the inner chimney 12 and the outer chimney 11, upper sealing covers 14 are provided on upper end surfaces of the outer chimney 11 and the inner chimney 12, and lower sealing covers 13 are provided on lower end surfaces of the outer chimney 11 and the inner chimney 12, that is, the water circulation area 15 is formed between the outer chimney 11, the inner chimney 12, the upper sealing cover 14, and the lower sealing cover 13.

The size of a water flow area 15 between the outer chimney 11 and the inner chimney 12 is preferably 50mm, a certain amount of water is pre-filled in the water tank 6, the water amount is larger than the volume of the water flow area 15, the water amount of the water tank 6 at least needs to be lower than the lowest water level of the water pump 4 when the water flow area 15 is full of water, the water pump 4 is connected with the water tank 6 through a hard pipeline, and the water outlet pipe 7 is also a hard pipe.

In order to avoid the phenomenon that the chimney 1 is rusted by water, the part between the outer chimney 11 and the inner chimney 12 is rusted, for example, the part between the outer chimney 11 and the inner chimney 12 is coated with paint or coated with metal with strong corrosion resistance, or hard film rust preventive oil is added into water, or the outer chimney 11 and the inner chimney 12 are made of stainless steel pipes.

The lower end of the water circulation area 15 is communicated with the water inlet pipe 2, and the upper end is communicated with the water outlet pipe 7. The rest is the same as in example 1.

The utility model discloses a theory of operation does:

after the power supply is switched on, the water pump 4 pumps water from the water tank 6, the water enters the water flow through area 15 between the outer chimney 11 and the inner chimney 12 from the water inlet pipe 2 and flows back to the water tank 6 from the water outlet pipe 7, the water flow through area 15 is always kept in a full water state, heat of the chimney 1 is taken out to play a role in cooling, and when water does not need to flow through, the valve 3 can be closed.
