Description

The invention relates to the technical field of industrial waste liquid treatment, in particular to a waste liquid combustion device.
Background
Dimethylformamide (abbreviated DMF), also known as N, N-dimethylformamide, is known as such because it is a dimethyl substituent of formamide, and both methyl groups are located on the N (nitrogen) atom. DMF is used as an important chemical raw material and a solvent with excellent performance, and is widely applied to industries such as polyurethane, acrylic fibers, food additives, medicines, pesticides, dyes, electrons and the like, and a large amount of chemical waste liquid (containing chemical substances such as dimethylformamide) is generated in chemical factories every day, and if the chemical waste liquid is directly discharged, the environmental pollution and natural damage can be caused, so that the chemical waste liquid treatment is indispensable, the existing waste liquid treatment comprises waste liquid incineration, organic waste liquid treatment or organic industrial waste liquid treatment, also called high-concentration organic waste liquid treatment, the waste liquid combustion is to atomize the waste liquid through high-pressure atomization equipment and then enter a combustion furnace, and in order to meet the complete combustion of the waste liquid in the process, the temperature of the combustion furnace needs to be increased, and the evaporation of the waste liquid is accelerated.
For example, chinese patent publication No. CN211232901U discloses a waste liquid high pressure atomization combustion device, its main structure includes combustion furnace, high pressure atomization device, fan, exhaust pipe, combustion furnace inner wall fixed mounting stove frame, stove frame top fixed mounting locating plate, locating plate inner wall fixed mounting the furnace, furnace left end fixed mounting high pressure atomization device, high pressure atomization device bottom fixed mounting the fan, combustion furnace top fixed mounting exhaust pipe, above-mentioned waste liquid high pressure atomization combustion device, combustion furnace inner wall top fixed mounting baffle, the effect of baffle is to get into exhaust pipe with smog from combustion furnace inner wall both ends, increases smog at the time of combustion furnace stay, makes the combustion furnace abundant burn waste liquid.
By carefully reading the above-mentioned waste liquid high pressure atomizing burner, it is not difficult to find that the above-mentioned waste liquid high pressure atomizing burner atomizes the industrial waste liquid and then discharges the industrial waste liquid to the furnace through the high pressure atomizing device for burning, and the instrument for discharging industrial waste liquid and the instrument for discharging the pilot medium are independent existence that does not influence each other, therefore, the discharge rate of industrial waste liquid and the discharge rate of pilot medium need be controlled alone, owing to do not possess synchronism between the two, consequently, can lead to the adaptability of waste liquid burning to reduce, can increase the operation degree of difficulty simultaneously to owing to the mixed degree between its industrial waste liquid and the pilot medium is lower, also can lead to the emergence of burning insufficient phenomenon.
For this reason, chinese patent publication No. CN209147109U discloses a waste liquid combustion apparatus, the main structure of which includes a collection tank for containing waste liquid fuel and a high-pressure air source for providing compressed air, the collection tank being connected to a waste liquid combustion furnace through a waste liquid pipe; taking the flow direction of the waste liquid as the downstream direction; the waste liquid combustion furnace comprises a steel furnace body, the horizontal section of the furnace body is circular, and a refractory clay layer is arranged on the inner wall of the furnace body; the lower end of the furnace body is closed, and the upper end of the furnace body is provided with an opening; the waste liquid pipe is connected to the lower part of the furnace body; the high-pressure air source is communicated with the waste liquid pipe through a high-pressure air pipe, the high-pressure air pipe is inclined towards the downstream direction of the waste liquid pipe, and the joint of the high-pressure air pipe and the waste liquid pipe is positioned at the downstream end part of the waste liquid pipe; the upstream end of the waste liquid pipe is provided with a first valve, and the high-pressure air pipe is provided with a second valve; an igniter is arranged at the opening of one end of the waste liquid pipe extending into the furnace body. The waste liquid combustion device can fully burn liquid fuel waste liquid generated in a laboratory, and can manufacture heat energy while eliminating potential safety hazards.
By carefully reading the above-mentioned waste liquid burner, it is not difficult to find that the above-mentioned waste liquid burner increases the flow distance between the industrial waste liquid and the ignition medium and the mixing ability of the spiral structure, thereby improving the mixing degree between the industrial waste liquid and the ignition medium, but it is obvious that it has the same defects as the waste liquid high-pressure atomizing burner: the apparatus for discharging the industrial waste liquid and the apparatus for discharging the pilot medium are independent without mutual influence, so that the discharge speed of the industrial waste liquid and the discharge speed of the pilot medium need to be controlled independently, and as the two are not synchronous, the adaptability of waste liquid combustion is reduced, and meanwhile, the operation difficulty is increased.

With respect to the specific structure of the adjustable combustion air supply structure 6, please refer to fig. 2, which includes an upper fixing ring 61 fixedly mounted on the inner wall of the middle section of the vertical combustion furnace 1, an annular protrusion structure 62 is disposed on the inner annular surface of the upper fixing ring 61, a medium flow area 63 with an upper end surface and a lower end surface in an open state is disposed in the center of the annular protrusion structure 62, an air injection pipe 64 with an integral structure and penetrating the side structure of the vertical combustion furnace 1 is disposed on the circumferential side surface of the upper fixing ring 61, in order to realize effective injection of air, the air injection pipe 64 is required to be connected with an exhaust port of an external blower through a pipe body, the annular protrusion structure 62 is disposed with an annular air flow hole 65 at the periphery of the medium flow area 63, a plurality of air discharge holes 66 disposed in an annular array with dots being disposed on the center line of the medium flow area 63 and communicating the annular air flow hole 65 with the medium flow area 63, an air 67 communicating an external space and the annular air flow hole 65 is disposed in the air injection pipe 64, in order to realize effective injection of air, and in order to realize effective injection of air, the air injection pipe 64 is required to be connected with an exhaust port of an external blower through the air inlet, and an air valve is disposed on the inner wall of the annular protrusion structure 62, and the spark plug is disposed on the inner wall of the spark plug 69.
