Silane and ammonia in PECVD tail gas, its working principle be silane contacted with the compressed air of input and nitrogen and spontaneous combustion or
Oxidation reaction occurs, a large amount of silica dust is generated after reaction；Ammonia absorbs to form ammonium hydroxide using water, and dust is then by air-flow
Band is into spray system and dissolves in water, over time, is then periodically discharged from the sewage draining exit of silicone hydride combustion tower bottom, burning is net
Tail gas after change detaches silicone hydride combustion tower by exhaust fan through feeding port from silicone hydride combustion tower, finds in actual operation, and burning is net
Air after change still deposits a small amount of silica dust, this part of silica dust can block filler after accumulating for a period of time,
To influence exhaust fan exhausting, so filler needs fixed time cleaning or replacement, but the silicone hydride combustion tower cleaning of existing structure needs to stop
Machine operation, operator enters in silicone hydride combustion tower from sewage draining exit to be operated, therefore will affect production, is caused damages, simultaneously
Operation is also inconvenient.
Utility model content:
Technical problem to be solved by the utility model is to provide a kind of high treating effect and easy cleaning silicone hydride combustion towers
Filler silane and ammonia processing system.
The technical solution of the utility model is to provide a kind of silane and ammonia processing system, including workshop is extended
The tail gas discharging pipe and silicone hydride combustion tower come, further includes the combustion barrel of precombustion processing, and combustion barrel is equipped with the air inlet of silane tail gas
Mouth, gas outlet and compressed air inlet port, tail gas discharging pipe are connect with silane tail gas air inlet, compressed air inlet port and compression
The inlet exhaust gas of air delivery pipe connection, gas outlet and silicone hydride combustion tower passes through piping connection, is equipped with vertically in silicone hydride combustion tower
Tower internal cavity is divided into the first cavity and the second cavity, the first cavity and the connection of the second cavity top by partition by partition, the
The clean-up port of the dust on cleaning filler is offered on the side wall of two cavity sides, clean-up port is located near feeding port.
After using the above structure compared with prior art, the utility model, which has the advantage that, is entering silicone hydride combustion tower
Before first pass through combustion barrel and carry out precombustion processing, the silica dust generated after making most of silane oxidation burn is deposited in combustion
It burns in cylinder, the not sufficient tail gas that burns, which continues to be discharged into silicone hydride combustion tower, to burn, and makes silane after-flame, while ammonia therein
It is soluble in water, ammonium hydroxide and silica dust are periodically discharged by sewage draining exit, meanwhile, in order to avoid silica dust product
Gather the influence suction ventilator exhausting on filler, clean-up port is opened up on silicone hydride combustion tower, clears up dust stratification under convenient not shutdown status, separately
Outside, special internal cavity is divided into two chambers by the setting of partition, is more advantageous to the processing of silica dust and ammonia.
Preferably, silicone hydride combustion tower includes tower body, the water storage of tower body bottom forms water tank, and tower body bottom is equipped with sewage draining exit,
Tower body top is equipped with spray equipment.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, a kind of silane and ammonia processing system, the tail gas discharging pipe 1 and silane to extend out including workshop
Combustion tower 2, further includes the combustion barrel 3 of precombustion processing, and combustion barrel 3 is equipped with silane tail gas air inlet 31, gas outlet 32 and pressure
Contracting air inlet, tail gas discharging pipe 1 and silane tail gas air inlet 31 are tightly connected, and compressed air inlet port is defeated with compressed air
Pipe is sent to connect, the inlet exhaust gas of gas outlet 32 and silicone hydride combustion tower passes through piping connection, is equipped with partition vertically in silicone hydride combustion tower 2
21, tower internal cavity is divided by the first cavity 22 and the second cavity 23 by partition 21, on the first cavity 22 and the second cavity 23
Portion is connected to, and the clean-up port 24 of the dust on cleaning filler is offered on the side wall of 23 side of the second cavity, and clean-up port 24, which is located at, to be filled out
Near material mouth.Add cover board at clean-up port 24, can at clean-up port welding flange, then cover board is fastened by bolts
Sealing is realized on clean-up port.The innovative point of the application is to increase pretreated combustion barrel and partition is arranged in silicone hydride combustion tower
And clean-up port is opened up on tower body, clean-up port is provided with above liquid level near feeding port, and other content is existing knot
Structure, such as blowpipe, workshop tail gas delivery pipe etc..
Silane tail gas enters combustion barrel by tail gas discharging pipe, while being also passed through compressed air from compressed air inlet port,
The characteristics of spontaneous combustion can occur is contacted with air according to silane, compressed air is used to push away the hypergolic reaction for helping silane tail gas, is allowed to shape
