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, guarantee 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, and wants to realize automatic operation, raises the efficiency.
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 can be realized automated production, and high insulating effect is energy-saving and cost-reducing, has good hot air heating system and waste gas absorbing system, and product quality is high.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of honeycomb fashion SCR denitrating catalyst secondary drying tunnel cave, comprise the drying alley kiln owner body, hot air supplier, the dry dolly that are provided with entrance and outlet, 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, described heater, pressure fan, circulating fan link together by air supply duct, and described dry dolly can enter in described drying alley kiln owner body.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.Described dry dolly can easily transport product and enter in described drying alley kiln owner body.
As preferably, in described drying alley kiln owner body, be provided with delivery track, described dry dolly is provided with the wheel mating with described delivery track.By described delivery track, dolly can one one be close to and enters in drying alley kiln owner body, convenient and swift, saves time, and has improved efficiency.
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.
As preferably, the porch of described drying alley kiln owner body is provided with hydraulic pusher structure.By described hydraulic pusher structure, dry dolly can enter described delivery track easily.
As preferably, the exit of described drying alley kiln owner body is provided with automatic traction device.Described automatic traction device can easily pull out the dry dolly in described drying alley kiln owner body.
As preferably, the body frame of described drying alley kiln owner body is shape, and the kiln body of described drying alley kiln owner body is thermal insulating composite panel, and entrance and the exit of described drying alley kiln owner body are provided with gate.Can improve the heat insulation effect in dry run.
Compared with prior art, the utlity model has following beneficial effect: 1, the utility model is realized continuously full-automatic production, reduces hand labor intensity, improved operating environment.
2, dry wind repeatedly circulates, is evenly dried, energy-saving and cost-reducing.
3, the fire-retardant coefficient of kiln body case of drying alley kiln owner body is high, and high insulating effect is energy-saving and cost-reducing.
4, design temperature curve, makes the heating of product experience, freeze-day with constant temperature, cooling overall process, produces continuously, guarantees the steady quality of product.
