Description
Technical field
This utility model relates to denitrating catalyst preparation field, particularly relates to one and is dried for honeycomb type denitrification catalyst
Tunnel cave.
Background technology
Along with living environment requirement is improved constantly by the mankind, NOx pollution problem is the most urgently to be resolved hurrily.And as administering
The SCR denitration technology of NOx pollution problem main flow, its 80% commercial catalyst used is honeycomb type denitrification catalyst.Honeycomb
In formula denitration catalyst agent producing process, determine being dried of predominantly catalyst of production cycle, traditional dry be generally divided into two
Step is dried, complex operation, and process is complicated, and uses the drying baker such as steam, hot blast or drying shed, and its arid cycle is long, typically up to
About 10 days, drying efficiency was low, and power consumption is big, against the original intention of minimizing environmental pollution, and can not meet continuous way production, simultaneously
May need to be equipped with the equipment such as boiler, increase investment.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of for producing honeycomb type denitrification catalyst continuously
Microwave tunnel dry kiln, this device is with microwave as heating source, in order to reaches energy-conservation, efficient, the purpose of environmental protection, shortens whole simultaneously
Individual catalyst arid cycle, and be dried and be more uniformly distributed.
This utility model is achieved through the following technical solutions:
For producing the microwave tunnel dry kiln of honeycomb type denitrification catalyst continuously, it is characterised in that:
Described microwave tunnel kiln is strip tunnel-type, and two ends are opening, and opening is provided with microwave suppressor having, tunnel
Bottom is laid by motor-driven conveyer belt along its length, and conveyer belt two ends are stretched out outside tunnel both ends open；
Configuring microwave rf generator on described microwave tunnel kiln, the waveguide of microwave rf generator stretches in kiln body tunnel, microwave
The microwave operational power adjustable of emission source；

Three is to control in time, be quick on the draw.Conventional heating means, such as steam heating, electric heating, Infrared Heating etc., reach
To certain temperature, need the regular hour, when breaking down or stop heating, the decline of the temperature long period again；And
Microwave power promptly can be transferred to required numerical value within the time of several seconds by microwave heating, is heated to suitable temperature, it is simple to
Automatization and continuous prodution；
Four is sanitation and hygiene, pollution-free.General industry firing equipment is bigger, and occupation of land is many, and ambient temperature also compares
Height, operator's labor condition is poor, and intensity is big.And microwave heating floor space is little, it is to avoid high ambient temperature, the work bar of workman
Part has obtained greatly improving, and by arranging microwave suppressor having on tunnel both ends open, micro-to environment of firing equipment
Wave radiation can the overwhelming majority be absorbed, and does not pollutes the environment.
Specifically adding man-hour, switch board starts conveyer belt, after honeycomb type denitrification catalyst material is sent into microwave tunnel kiln, micro-
Ripple emission source starts, and starts to be dried material process, and adjusts the microwave operational merit of microwave rf generator in dry run
Real needs to microwave energy when rate is to adapt to material humidity difference, meanwhile, the breeze fan of microwave tunnel kiln start into
Row forced ventilation, the wet-emitting blower of opposite side carries out forced exhaust, makes the catalyst feed in microwave tunnel kiln at drying course
In, steam and heat in duct are discharged in time, to ensure to dry uniformly, improve drying efficiency, reduce what localized hyperthermia caused
Catalyst ftractures；After Gan Zaoing, conveyer belt is again by dried material output, in order to follow-up continuous production.
Further, described waveguide is perpendicular to length of tunnel direction, in the middle part of kiln body tunnel, is not only convenient for arranging, structure
Compact, and ensure that the most overall efficiency of heating surface in tunnel.
Further, described conveyer belt is the rustless steel transmission chain along the configuration of interval, length of tunnel direction or PP conveyer chain
Bar.Use rustless steel can high temperature resistant, anticorrosion, delay apparatus service life；In microwave heating equipment it is not recommended that use metal system
Product, are because metallic article microwave reflection, heated article produce shielding action, and this kind of metallic article generally half seals
Close or full hermetic container formula, and the conveyer belt of this equipment is placed in bottom of article, and be hollow out, do not affect microwave article are carried out
Omnibearing even heats.PP polypropylene has good thermostability, and chemical stability is fine, and degree of crystallinity is high, compound with regular structure,
Thus there is excellent mechanical property, it is highly suitable as the transmission chain of drying alley kiln.
Further, the tunnel width of described microwave tunnel kiln is more than or equal to the axial dimension of honeycomb type denitrification catalyst,
Tunnel height is more than or equal to honeycomb type denitrification catalyst radial dimension, and it is horizontal that honeycomb type denitrification catalyst is perpendicular to length of tunnel direction
To being held on conveyer belt.Catalyst feed use transverse horizontal sample introduction, can ensure as far as possible single material generally in
In same temperature region, temperature is more uniformly distributed.
Further, described breeze fan and wet-emitting blower are along microwave drying segment length direction, respectively in relative both sides
Kiln wall interval is arranged multiple, to ensure more preferable dehumidifying waste discharge effect.
Further, the sidewall of described microwave tunnel kiln is provided with sample viewing window, it is simple to field monitoring personal observations is relatively
In long tunnel cave, the drying regime of zones of different material, in order to adjust microwave power and process time in time, to ensure more preferably
Drying effect.
Further, described microwave tunnel kiln uses 304 rustless steel kiln body or 316L rustless steel kiln body rustless steel kiln body
Anticorrosion is raw, it is possible to extend the service life of tunnel cave.
The beneficial effects of the utility model are: efficiently, thoroughly, drying time is short for the dehydration of this device, in dry run, by
Inside and outside catalyst, absorb microwave simultaneously thus produce heat, therefore material inside and outside uniform drying, reach to be dried equally result
Under, it being only original 15-25% arid cycle, energy consumption is original 40-60%.
