Description
Technical Field
The utility model relates to a waste gas waste liquid stokehold premixing device belongs to energy-concerving and environment-protective technical field.
Background
At present, in a waste liquid and waste gas or heat accumulation incineration system, when waste liquid and high-concentration waste gas are contained, the adopted method is that the high-concentration waste gas directly enters an incinerator for incineration, the waste liquid directly enters the incinerator through a spray gun, and air is supplemented with air for combustion supporting through an air chamber and an air nozzle. High-concentration waste gas directly enters the incinerator, so that the temperature of a hearth in the area of a waste gas inlet is low, the combustion is insufficient, the combustion efficiency is low, meanwhile, the waste liquid is directly sprayed into the incinerator for combustion and is insufficiently mixed with oxygen supplement in the incinerator, and the air supplement in the incinerator increases the consumption of materials such as an air chamber, an air nozzle and the like and the selection of materials.
Disclosure of Invention
An object of the utility model is to provide a waste gas waste liquid stokehold premixing device to overcome the problem that above-mentioned prior art exists.
The utility model adopts the technical proposal that: the utility model provides a waste gas waste liquid stokehold premixing device, is equipped with the co-combustion part including burning.
Furthermore, the mixing part body is also provided with a flame detection port and a long open fire interface, a burner is arranged in the long open fire interface, and a flame detector is arranged in the flame detection port. Wherein, preferably, the front end of the flame detection port is arranged in a horn shape for increasing the detection visual angle.
Further, an inner rotary blade is arranged at the position, close to the outlet end, of the waste gas chamber, and the inner rotary blade is fixed between the inner wall of the waste gas chamber and the outer wall of the waste liquid spray gun and is used for providing inner support for the waste liquid spray gun.
Further, an outer swirl vane is arranged at the end of the air chamber close to the outlet, is fixed between the inner wall of the air chamber and the outer wall of the exhaust gas chamber and is used for providing in-pipe support for the exhaust gas chamber.
The utility model has the advantages that: the device skillfully combines the waste liquid, the waste gas, the combustion-supporting fuel and the air to be incinerated, and the waste liquid, the waste gas, the combustion-supporting fuel and the air enter the incinerator after being premixed, so that the combustion is more sufficient, and the layout is more reasonable.
In the device, all waste liquid and waste gas to be incinerated enter the combustion part after being premixed, enter the incinerator at the burner point of the combustion part and under the combustion supporting effect, and because the high-concentration waste gas and the combustion supporting air enter the combustion part at a high speed and tangentially, the high-concentration waste gas and the combustion supporting air advance spirally along the refractory material at the rear section to play a role in protecting the refractory material, and meanwhile, the retention time of the flue gas in the incinerator is increased, so that the waste gas and the waste liquid are more sufficiently combusted.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
