Abstract
The utility model relates to a ceramic roller kiln combustion air heating device, which belongs to the technical field of ceramic roller kiln. The utility model utilizes the waste heat of a kiln to get high-temperature combustion air so as to improve the quality of products and reduce fuel consumption and electricity consumption. Thereby a main heat exchanger is arranged inside a kiln cooling belt, in particular to a splat cooling belt; an air inlet of the main heat exchanger is connected with a lower outlet of an air main; an air outlet of the main heat exchanger is connected with corresponding air inlet of a branch air pipe. A branch heat exchanger can be arranged on a slow cooling belt and the splat cooling belt, and the high-temperature combustion air is transferred to each ejection gun by each branch air pipe respectively.
Description
Technical field
The utility model relates to the ceramic roller kiln technical field, particularly a kind of ceramic roller kiln combustion air heater.
Background technology
The combustion air that the spray gun that existing ceramic roller kiln supply cloth comes the kiln both sides is used is the normal temperature combustion air, it is to suck natural air by the roots blower that is arranged on Yao Ding top, deliver on every spray gun at the branch wind pipe branch of kiln both sides by air main and cloth, to satisfy the required air of fuel combustion.Adopt the normal temperature combustion air can have following shortcoming: (1) burnup, power consumption height; (2) the kiln cross section temperature difference is big, and goods flatness, dimensional discrepancy, aberration are wayward; (3) because roller kilns output is big, and goods can discharge a large amount of heat energy in cooling procedure, wherein sub-fraction heat energy is supplied with baker oven dry biscuit, and most of heat energy all is not converted into effective heat energy, so the heat energy utilization rate is low.
Summary of the invention
The technical problems to be solved in the utility model is to utilize the waste heat of kiln itself to obtain the high temperature combustion air, thereby improves quality of item, reduces burnup, power consumption.
The technical solution that the utility model proposed is such: a kind of ceramic roller kiln combustion air heater, comprise the roots blower that is contained in top, kiln top, its air outlet is connected with the air main upper port, the branch wind pipe and each the spray gun air inlet that are contained in kiln two examples are connected in parallel, the air main lower port is located in the kiln salband, described branch wind pipe air inlet also is located in the kiln salband, in the kiln salband, main heat exchanger is housed, this main heat exchanger air inlet is connected with the air main lower port, and its air outlet is connected with corresponding branch wind pipe air inlet.Described main heat exchanger is contained in the chilling band top in the salband.Described main heat exchanger is contained in chilling band bottom.Described chilling band top, bottom all are equipped with main heat exchanger simultaneously.Slow cooling band and/or fast cold belt at salband are equipped with a heat exchanger, and this heat exchanger is serially connected between main heat exchanger and the corresponding branch wind pipe air inlet.A described main heat exchanger and a heat exchanger all adopt snakelike air channel structure, the uniform heat exchanger fin group that is parallel to airflow direction that is fixed with in the air channel.The material of described heat exchanger is a heat-resistance stainless steel.Described branch wind pipe is installed in kiln two inboards, will install expansion joint additional on branch wind pipe.
Compared with prior art, the utlity model has following beneficial effect:
(1) salband of roller kilns is made up of chilling band, slow cooling band, fast cold belt, goods when the over-quenching band by about maximum temperature rapid drawdown to 700 ℃, the thermal discharge maximum, rate of heat exchange is fast, and handling is good, so, the main heat exchanger optimum is installed in chilling band position, and heat exchanger can be installed on slow cooling band or the fast cold belt position, and whether a heat exchanger is installed, and depends on combustion air temperature required and decide.Because the heat energy that goods coolings is discharged part exchange is given combustion air, thereby goods cool off required cooling air quantity and can reduce, thereby have reduced the power consumption of cooling blower.
(2) heat energy that combustion air brought has improved kiln internal combustion temperature significantly, when the temperature of combustion air improves 200 ℃, use producer gas or blast furnace gas and can make that theoretical temperature combustion improves 100 ℃ in the kiln, can make as using heavy oil or natural gas that theoretical temperature combustion improves 150 ℃ in the kiln.Obviously, under the kiln same case, reach identical kiln temperature, then adopt the required fuel of high temperature combustion air few, the combustion air of consumption is also few.
(3) after high temperature combustion air and the fuel mix, improved the fuel initial temperature value, can reduce fuel-viscosity variation, make it atomizing fully, or improve liquefaction vapour gasification rate, lower tar viscosity in the coal gas, prevent coking, flammable mixture burns more fully, reaches the ignition temperature required time and has shortened, reaction speed, combustion reaction band temperature, all corresponding raising of gas conduction coefficient.In a word, fuel combustion speed, efficient, intensity all significantly improve, and combustion flame obviously shortens, definition obviously increases, and like this, flue gas injection speeds up in the kiln, have reduced the cross section temperature difference in the kiln, and the goods flatness is good, dimensional discrepancy, aberration diminish.
(4) can not influence other operations of kiln after the combustion air heat exchange heats up, traditional UTILIZATION OF VESIDUAL HEAT IN is unaffected, thereby has improved the utilization efficiency of heat energy of kiln.
