Description
Technical field
The utility model is related to field of household garbage incineration, especially a kind of denitrating system urea feeding device.
Background technology
The NOx emission standard of Some Domestic garbage burning factory has reached 2000 standard limit of smog release of European Union, with flue gas emission
The continuous improvement of standard realizes that minimum discharge zero-emission has become the trend of waste incineration and generating electricity industry development, and therefore, rubbish is burnt
Factory is burnt for denitrification reducing agent（Urea）Demand be also constantly to be promoted, and urea feeding becomes a great problem.
Currently, the major way of urea feeding is electric gourd hang or vacuum feeder, but is taken using electric block feeding,
Time and manpower are not only expended, but also realizes that automation runs in the opposite direction with denitrating system；And vacuum feeder is used, pipeline is easy
It blocks, equipment failure rate is high, therefore, it is imperative to develop suitable denitrating system urea feeding device.
Invention content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, propose a kind of denitrating system urea feeding dress
It sets.It is by denitrification reducing agent（Urea）Urea tank is added, urea is delivered to above urea tank by bucket elevator, then pass through elephant trunk
Urea is added to urea tank.
The utility model specific technical solution is：A kind of denitrating system urea feeding device, by bucket elevator, Pneumatic three-way
Valve, elephant trunk, pneumatic gate valve, air accumulator, filter, freeze drier, pneumatic baffle, bucket elevator access path are constituted；It is described
Bucket elevator is arranged by urea tank, and the Pneumatic three-way valve setting is exported in bucket elevator, and the elephant trunk is arranged in Pneumatic three-way valve
Outlet, urea tank top, the pneumatic gate valve are arranged in elephant trunk end, the air accumulator, filter, freeze drier, gas
Dynamic baffle plate setting is arranged in compressed air line, the bucket elevator access path below bucket elevator.
The operation principle of the utility model is：Urea granules are delivered to by bucket elevator above urea tank, then by pneumatic
Urea granules are added to urea tank for triple valve and elephant trunk, complete the feeding of urea granules, and pneumatic plate is arranged in elephant trunk end
Valve and compressed air inlet prevent moisture in tank from entering elephant trunk, lead to urea crystals in elephant trunk.It is arranged on compressed air hose road
The impurity in filter filtering compressed air is arranged with constant compression air pressure in air accumulator, and setting freeze drier removes pressure
Moisture in contracting air.
Description of the drawings
Fig. 1 is the denitrating system urea feeding device structural schematic diagram of the utility model.
In figure：1- bucket elevators, 2- Pneumatic three-way valves, 3- elephant trunks, 4- pneumatic gate valves, 5- air accumulators, 6- filters, 7- are cold
Lyophilizer, 8- pneumatic baffles, 9- bucket elevator access paths.
Specific implementation mode
As shown in Figure 1, the denitrating system urea feeding device structural schematic diagram of the utility model, by bucket elevator 1, pneumatic three
Port valve 2, elephant trunk 3, pneumatic gate valve 4, air accumulator 5, filter 6, freeze drier 7, pneumatic baffle 8, bucket elevator access path 9
It constitutes.Bucket elevator is buried setting, and ground divides into access path to overhaul, about 2 meters deep；Pneumatic three-way valve setting goes out in bucket elevator
Mouthful, it can realize two urea tanks charging or single charging simultaneously by controlling；Elephant trunk is arranged in Pneumatic three-way valve outlet, and material is
PTFE prevents urea granules from gluing wall；Pneumatic gate valve is arranged in elephant trunk end, after charging, closes pneumatic gate valve, prevents tank
Interior moisture enters elephant trunk；Elephant trunk end pneumatic gate valve upper end be arranged compressed air inlet port, every time charging after, in elephant trunk into
Row purging；Air accumulator is arranged in compressed air line, constant compression air pressure；Pipeline is arranged before and after air accumulator in filter,
To the impurity in filtering compressed air；Freeze drier is arranged in air accumulator front end pipeline, to drying compressed air；Pneumatically
Baffle plate setting is in compressed air outlet pipeline, to control the keying of purging wind.
Bucket elevator described in above-mentioned the utility model, Pneumatic three-way valve, elephant trunk, pneumatic gate valve, air accumulator, filtering
Device, freeze drier, pneumatic baffle, bucket elevator access path are formed using existing part, these parts belong to known technology,
Related above-mentioned part, those skilled in the art understand, and details are not described herein.
The operation principle of the utility model is：Urea granules are delivered to by bucket elevator above urea tank, then by pneumatic
Urea granules are added to urea tank for triple valve and elephant trunk, complete the feeding of urea granules, and pneumatic plate is arranged in elephant trunk end
Valve and compressed air inlet prevent moisture in tank from entering elephant trunk, lead to urea crystals in elephant trunk.It is arranged on compressed air hose road
The impurity in filter filtering compressed air is arranged with constant compression air pressure in air accumulator, and setting freeze drier removes pressure
Moisture in contracting air.
The course of work of the utility model is：
1. jumbo bag urea is transported to bucket elevator hopper with fork truck, urea is delivered to above urea tank by bucket elevator 1.
2. urea enters one or two elephant trunks 3 by Pneumatic three-way valve 2.
3. opening pneumatic gate valve 4, urea granules enter urea tank, after the completion of discharging, close pneumatic gate valve 4, beat
Open pneumatic baffle 8, compressed air is by filter 6, air accumulator 5, is purged into elephant trunk after freeze drier 7.
It is used when 4. bucket elevator maintenance logical 9 is overhauling bucket elevator.
To sum up, urea granules are delivered to by bucket elevator above urea tank, then by Pneumatic three-way valve and elephant trunk by urea
Particle is added to urea tank, completes the feeding of urea granules, and pneumatic gate valve and compressed air inlet is arranged in elephant trunk end, prevents
Only moisture enters elephant trunk in tank, leads to urea crystals in elephant trunk, realizes the convenient and efficient of urea feeding, time saving and energy saving.
