Abstract
The utility model relates to a residual-heat utilization device of a ceramic calcining kiln, which is provided with at least two residual-heat gas collecting and conveying pipelines. One end of the pipeline is connected and communicated with a smoke outlet at the front part of the ceramic calcining kiln and a gas outlet at the tail part of the ceramic calcining kiln, the other end of the pipeline is connected and communicated with a hot air inlet of a green part drying kiln, and a draft fan is arranged at one end of the residual-heat gas collecting and conveying pipeline. Due to the device, the residual heat of waste gas discharged by the smoke outlet of a preheating section at the front part of the ceramic calcining kiln and the gas outlet of a cooling section at the tail part of the ceramic calcining kiln is utilized fully, so that the environmental pollution caused by the waste gas can be avoided. Simultaneously, the investment of an independent heat supply system for the green part drying kiln and the energy consumption can be saved, the energy consumption for the ceramic production can be saved by near 20%, and the production cost of the ceramic production can be greatly reduced.
Description
Technical field
The utility model belongs to using residual heat from kiln furnace and utilizes technical field, particularly a kind of ceramic kiln residual heat using device.
Background technology
Architectural pottery industrial energy problem is comparatively outstanding at present.China's architectural pottery industry is fuel with coal, natural gas mainly, is power with a large amount of electric energy, is typical big power consumer.And the energy utilization rate of China's architectural pottery industry with abroad compare, gap is bigger, the energy utilization rate of developed country is generally up to more than 50%, and China only reaches 28%-30%.In the general technology flow process of ceramic industry, energy consumption is mainly reflected in raw material processing, moulding, drying and burns till this four part.Wherein drying and firing process, both energy consumptions account for 80%.General calcining kiln length is more than 200m, and firing temperature is 1200～1220 ℃, and maximum sintering temperature can reach 1300 ℃, so about 60% is used for firing process in the ceramic industry energy consumption.Dry kiln mainly is that product is carried out drying, this equipment mostly is roller bed type, first base after the moulding is driven to roll in drier by rod iron and travels forward, hot gas at inner face with first base drying, for the next procedure glazing creates conditions, the baking temperature of dry kiln is about 150～200 ℃, and energy consumption accounts for 20% of ceramic enterprise total energy consumption.In technique known, traditional ceramic kiln thermal efficiency is very low, has 60%～70% heat to discharge by kiln hood and kiln tail nearly, is not well recycled.
The utility model content
The purpose of this utility model provides and a kind ofly can effectively utilize residual heat resources, exhaust gas discharged recovery in the ceramic kiln is delivered in the dry kiln, and energy savings consumption reduces the kiln exhaust gas discharging, reduce production costs, reach the ceramic kiln residual heat using device of effects of energy conservation and environmental protection.
Realize that the technical scheme that the purpose of this utility model is taked is: this device has the waste heat gas gathering line more than at least 2, one end of waste heat gas gathering line is connected and is communicated with the exhaust opening of ceramic kiln front portion and the exhaust outlet of ceramic kiln afterbody respectively, the other end is connected and is communicated with the first hot blast air inlet of base dry kiln, is provided with air-introduced machine at an end of waste heat gas gathering line.
Length≤the 20m of described waste heat gas gathering line.
The ceramic kiln residual heat using device of making according to such scheme, setting by waste heat gas gathering line, the waste gas residual heat that the exhaust outlet of the exhaust opening of the anterior preheating section of ceramic kiln and ceramic kiln afterbody cooling section is discharged is fully utilized, and the environmental pollution of having avoided toxic emission to cause.Also saved simultaneously the investment and the energy resource consumption thereof of the independent heating system of first base dry kiln, it is nearly 20% that the Production of Ceramics total energy consumption is saved, and the ceramic product production cost reduces greatly.Advantages such as device has simple and reasonable, and serviceability is reliable, and is easy and simple to handle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, ceramic kiln residual heat using device of the present utility model is the waste heat gas gathering line 4,7 that lays between ceramic kiln 1 and first base dry kiln 2 more than at least 2.One end of waste heat gas gathering line 4,7 is connected and is communicated with the exhaust opening 6 of ceramic kiln 1 anterior preheating section and the exhaust outlet 9 of ceramic kiln 1 afterbody cooling section respectively, the uniform hot blast air inlet 3 of the other end and first base dry kiln 2 one sides is connected and is communicated with, and is provided with air-introduced machine 5,8 between the exhaust outlet 9 of an end of waste heat gas gathering line 4,7 and ceramic kiln 1 anterior exhaust opening 6 and afterbody cooling section.The flue gas that the exhaust outlet 9 of the exhaust opening 6 of ceramic kiln 1 anterior preheating section and ceramic kiln afterbody cooling section is discharged and take hot air temperature all about 300 ℃, and the baking temperature of first base dry kiln 2 is generally at 150～200 ℃, in the defeated process of collection, produce excessive temperature drop for fear of waste heat gas, should shorten the structure distance of ceramic kiln 1 and first base dry kiln 2 as far as possible, make the length≤20m of waste heat gas gathering line 4,7.The waste gas residual heat that the exhaust outlet 9 of the exhaust opening 6 of ceramic kiln 1 anterior preheating section and ceramic kiln afterbody cooling section is discharged is fully utilized the environmental pollution of having avoided toxic emission to cause; On the other hand, saved the independent heating system of first base dry kiln 2, thereby made the Production of Ceramics total energy consumption save nearly 20%.
