The honeycomb type SCR denitration catalyst two-level drying tunnel kiln is provided with a good hot air heating system and a waste air sucking system and can improve product quality, and labor intensity is low.
Description
Technical field
The utility model relates to a kind of drying device, is specifically related to a kind of secondary drying tunnel cave for the production of honeycomb fashion SCR denitrating catalyst.
Background technology
Due to mankind's activity and economic fast development, China's environment is seriously damaged, and extreme climate showed increased causes serious threat to people's life and property, causes heavy losses to country, has hindered the sustainable development of national economy simultaneously.Country has also paid huge cost in order to administer environment.
The current discharged nitrous oxides total amount of China has exceeded 1,800 ten thousand tons, if do not take effective control measure, 5 years Chinese nitrogen oxide emissions of Future Ten will continue to increase, and may reach more than 3,000 ten thousand tons to the year two thousand twenty.China is coal-fired big country, and coal-burning power plant is the primary emission source of nitrogen oxide, accounts for 40% of total amount, will become the first batch of control object of country.
Honeycomb ceramics SCR denitrating catalyst Main Function is by the NO in discharging waste gas
xconvert nitrogen and steam to, to reach environmental emission standard.
SCR device is mainly made up of two large main bodys: remove agent preparation system and reactor body.By spray into reactant NH in reactor
3, NOx is reduced to nitrogen.Because this reduction reaction is comparatively responsive to temperature, therefore need add catalyst with intensified response activity, meet the temperature requirement of reaction.
Honeycomb fashion SCR denitrating catalyst main component generally comprises nano-TiO
2, V
2o
5and WO
3.These three kinds of shared catalyst ratios of composition exceed 95 ﹪, and TiO
2proportion is generally 80%～85%.In order to meet production technology needs, ensure easy extrusion modling, also needing in addition to increase the mixture additives such as some viscose glues and glass fibre increases pug intensity and mobility, adjusts its physical property.Due to these compositions stir mixing rear mobility and plasticity poor, moulding difficulty is larger.Again because the water holding capacity of product is poor, atmospheric crack very easily after moulding is also higher to the production engineering specifications of dry kiln.In dry run, can produce some NH
3, SO
3deng corrosive gas, the quality of product is had to certain influence, therefore, dry kiln need to possess good heating system and waste gas absorbing system.
Summary of the invention
The utility model provides a kind of honeycomb fashion SCR denitrating catalyst secondary drying tunnel cave.This secondary drying tunnel cave has good hot air heating system and waste gas absorbing system, can improve the quality of product, and artificial intensity is little.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: honeycomb fashion SCR denitrating catalyst secondary drying tunnel cave, comprise be provided with entrance and outlet for place honeycomb fashion SCR denitrating catalyst idiosome drying alley kiln owner body, hot air supplier, it is characterized in that, also comprise the air-introduced machine for extracting waste gas, described hot air supplier comprises heater, pressure fan, circulating fan, and described heater, pressure fan, circulating fan link together by air supply duct.Described heater heats with wind for being dried, blower-use is in dry after heating delivered to air supply duct with wind, circulating fan extracts the hot blast in air supply duct product is carried out to heat drying, the waste gas producing is discharged through described air-introduced machine, this air circulation system can well heat product, combustion gas simultaneously, reduces the impact of waste gas on product.
As preferably, described circulating fan is crisscross arranged in the both sides of described drying alley kiln owner body.Such setting makes hot blast rationally penetrate the cellular space of product to carry out repeatedly circulating-heating, dry, effective.
As preferably, described pressure fan is connected with frequency-variable controller.Can control overall air output, and then control temperature.
As preferably, described air-introduced machine is connected with frequency-variable controller.Can control overall exhaust air rate.
Compared with prior art, the utlity model has following beneficial effect: 1. dry wind repeatedly circulates, is evenly dried, energy-saving and cost-reducing.
2. design temperature curve, makes the heating of product experience, freeze-day with constant temperature, cooling overall process, produces continuously, ensures the steady quality of product.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail: referring to accompanying drawing, honeycomb fashion SCR denitrating catalyst secondary drying tunnel cave, comprise be provided with entrance and outlet for placing drying alley kiln owner body 7, the hot air supplier of honeycomb fashion SCR denitrating catalyst idiosome, also comprise the air-introduced machine 5 for extracting waste gas, described hot air supplier comprises heater 2, pressure fan 3, circulating fan 4, and described heater 2, pressure fan 3, circulating fan 4 link together by air supply duct 9.In present embodiment, described circulating fan 4 is crisscross arranged in the both sides of described drying alley kiln owner body 7.Described pressure fan 3 is connected with frequency-variable controller.Described air-introduced machine 5 is connected with frequency-variable controller.
When work, product is put into drying alley kiln owner body 7, heater 2 heats with wind dry, and pressure fan 3 is sent into dry after heating in air supply duct 9 with wind, and circulating fan 4 extracts the hot blast in air supply duct 9, blows to product.Because circulating fan 4 shifts to install in the both sides of described drying alley kiln owner body 7, hot blast can rationally penetrate the cellular space of product and carry out circulating-heating, dry, and drying effect is good.Meanwhile, the waste gas producing in dry run is got rid of by air-introduced machine 5, makes product quality unaffected.
Described pressure fan 3 is connected with frequency-variable controller, and described air-introduced machine 5 is connected with frequency-variable controller.The amount of adjustable air-supply and air draft, the temperature of adjusting drying alley kiln owner body 7, reaches better drying effect.
