Description

Technical Field

[0001] The present invention relates to the technical field of waste liquid treatment equipment, in particular to a spray gun type waste liquid incinerator. Background Art

[0002] Spray-type waste liquid incinerators are core equipment for treating high-concentration organic waste liquids and are widely used in the chemical, pharmaceutical, petroleum refining, and hazardous waste disposal industries. Through the synergistic effect of atomization and high-temperature incineration, they completely decompose toxic and hazardous substances in waste liquids, offering the advantages of both volume reduction and harmlessness.

[0003] A typical lance-type incinerator consists of a cylindrical furnace, burner, waste liquid atomizer, and air supply. The furnace body is typically a vertical cylindrical steel structure lined with refractory material. The burner is located on the side of the furnace, providing the initial ignition heat source and maintaining a high temperature environment within the furnace. The waste liquid atomizer is coaxially fixed to the top of the furnace, atomizing the waste liquid into droplets for downward spraying. The air supply injects combustion-supporting air into the furnace to ensure sufficient combustion.

[0004] Under the coordinated action of various components of the incinerator, the waste liquid forms fine droplets and is sprayed into the furnace at high speed. It quickly absorbs heat and evaporates in the high-temperature flue gas, and undergoes an oxidation reaction after mixing with the air, decomposing into harmless substances such as carbon dioxide and water. The residual ash is discharged through the ash outlet at the bottom.

[0005] However, the limitations of traditional lance-type incinerators are becoming increasingly prominent: after being atomized, the droplets are sprayed essentially along the axial direction of the furnace body. During this process, some droplets located on the outer edge are sprayed in a direction essentially parallel to the inner wall of the furnace body. After adhering to the inner wall, they move rapidly downward along the furnace wall, resulting in insufficient residence time in the combustion area, which can easily lead to incomplete incineration. In other words, the "short-circuiting" phenomenon of the droplets can lead to incomplete combustion of the waste liquid and increase the risk of coking on the furnace wall. Although existing technologies have attempted to improve combustion by optimizing atomization parameters or adding secondary air, the "edge effect" caused by the droplet flow adhering to the wall has not been effectively addressed. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a lance type waste liquid incinerator.

[0007] The lance-type waste liquid incinerator proposed in the present invention comprises a furnace body and a waste liquid atomizer placed on the top of the furnace body, a burner and an air inlet are provided on the side of the furnace body, and an ash outlet is provided at the bottom of the furnace body;

[0008] Different from the traditional structure, in this solution, the waste liquid atomizer includes a nozzle and a drive assembly. The central axis of the nozzle forms an angle with the central axis of the furnace body, and the nozzle is arranged to rotate relative to the furnace body. The drive assembly is used to drive the nozzle to rotate.

[0009] That is, the spraying direction of the nozzle is arranged to be non-coaxial with the furnace body, and the nozzle is rotatable by the driving assembly, so that the spray gun type waste liquid incinerator has the following advantages:

[0010] 1. The spray direction of the waste liquid droplets is not parallel to the inner wall of the furnace body. After the droplets collide with the furnace wall, they will be reflected and reflected back and move toward the middle of the furnace body, so there will be no short circuit caused by adhesion to the furnace wall and rapid drainage by the furnace wall;

[0011] Second, the rotating nozzle prevents the sprayed droplets from continuously colliding at the same position on the furnace wall. Instead, they are sprayed circumferentially along the furnace wall. Even if a small amount of droplets short-circuit, they will not continue to form coke at the same position, which is beneficial to maintaining the incineration efficiency of the furnace body.

[0012] In some examples of the present invention, the waste liquid atomizer further comprises a housing, and a central axis of the nozzle forms an angle with a central axis of the housing;

[0013] The central axis of the nozzle and the central axis of the housing intersect within the housing, and the nozzle and the housing are rotatably connected at the intersection. The nozzle and the housing are rotatably connected at an end away from the intersection via a plurality of first spheres, and the diameters of the plurality of first spheres increase from one side of the nozzle to the other side.

[0014] The purpose of this arrangement is to achieve the rotatable function of the nozzle by arranging a rotatable connection between the nozzle and the shell, thereby avoiding the nozzle being directly connected to the furnace body. In addition, this connection method between the nozzle and the shell can achieve the central axis of the nozzle to deviate from the central axis of the shell, and at the same time form an intersection between the two. The first spheres with increasing diameters from one side of the nozzle to the other side can achieve the rotational connection between the nozzle and the shell in a tilted state.

[0015] In this way, when the nozzle is driven to rotate, it rotates at the "intersection" mentioned above, while other parts of the nozzle also revolve around the central axis of the shell, so that the spraying direction of the nozzle is not parallel to the furnace body, but can also change along the circumference of the furnace body.

[0016] In some examples of the present invention, a first ball bracket is connected to the nozzle corresponding to each first ball, each first ball bracket is recessed to form a groove for the corresponding first ball to be placed and rotate freely, and a first annular groove is formed on the inner wall of the shell corresponding to the first balls;

[0017] The purpose of such a configuration is to connect the first sphere to the nozzle so that when the nozzle rotates, the first spheres can follow the nozzle in revolution. At the same time, the first spheres can also rotate under the interference of the first annular groove, thereby assisting the rotation of the nozzle.

[0018] At the same time, the connection between the first sphere and the first sphere bracket can also support the nozzle, so that the nozzle is relatively connected to the shell and prevented from being separated from the shell.

[0019] In some examples of the present invention, the nozzle and the housing are rotatably connected at the intersection of their central axes by a plurality of second spheres having the same diameter, and the plurality of second spheres are distributed along the circumference of the nozzle;

[0020] A second ball holder is connected to a position on the nozzle corresponding to the second ball. The second ball holder is annular and has a plurality of through grooves formed on the second ball holder corresponding to the plurality of second balls, in which the second balls can be placed and rotated freely. When the second balls are placed in the through grooves, one end of the second balls contacts the outer wall of the nozzle and the other end is placed in the second annular groove formed on the inner wall of the shell.

[0021] The purpose of such a setting is that the nozzle only rotates at the position corresponding to the second sphere, and the second sphere with the same diameter can realize the rotation function of the nozzle at this position;

[0022] Similarly, the connection between the second sphere and the second sphere bracket can also support the nozzle, so that the nozzle is relatively connected to the shell and prevented from being separated from the shell.

[0023] In some examples of the present invention, the drive assembly includes a rotating shaft coaxially arranged with the central axis of the housing, the rotating shaft being rotatably arranged relative to the housing, a cross body being provided at one end of the rotating shaft proximate to the nozzle, a connecting block being coaxially arranged with the nozzle at one end of the nozzle proximate to the cross body, the connecting block being recessed at an eccentric position thereof to form a cross groove into which the cross body can be placed, and a gap being provided between the cross body and the cross groove;

[0024] The purpose of this setting is: since the nozzle will revolve, the position of any point on its end will change during the rotation process, while the shaft produces self-rotation. Therefore, when the shaft drives the nozzle to rotate, a certain gap needs to be reserved for the cooperation between the two. The use of the cross and cross groove is to increase the contact area between the two and enhance the transmission force.

[0025] In some examples of the present invention, the cross body and the rotating shaft are connected to each other in a relatively sliding manner, an elastic body is provided between the cross body and the rotating shaft, and the elastic direction of the elastic body points between the rotating shaft and the cross body;

[0026] The purpose of such a setting is that when the nozzle is rotated by driving the connecting block through the cross, the connection method between the cross body and the rotating shaft further reserves space for the cross to tilt, twist or displace, so that when there is possible interference between the cross and the connecting block, the cross can offset the interference through changes in space; the elastic body is used to exert a certain pressure on the cross, so that it has continuous contact with the connecting block and drives the connecting block to rotate.

[0027] In some examples of the present invention, a waste liquid channel is provided in the nozzle, one end of the waste liquid channel extends to an end of the nozzle away from the drive assembly to form a waste liquid spout, and the other end extends to the side of the nozzle, a first annular disc is provided between the nozzle and the housing, and a waste liquid docking channel is provided on the first annular disc to connect the waste liquid channel with a waste liquid inlet provided on the housing;

[0028] The purpose of such arrangement is that, since the waste liquid channel will rotate along with the nozzle, and the waste liquid inlet needs to be relatively fixed, a waste liquid docking channel opened on the first annular disc is provided to connect the two.

[0029] In some examples of the present invention, the first annular disc is fixedly connected to the nozzle, the waste liquid docking channel includes a first annular channel opened at the outer edge of the first annular disc and extending circumferentially along the first annular disc, the first annular channel being connected to the waste liquid inlet, and the waste liquid docking channel further includes a first radial channel connected to the first annular channel at one end and to the waste liquid channel at the other end;

[0030] The purpose of such a setting is to connect the first annular disk to the nozzle so that the first annular disk can rotate with the nozzle, so that the first annular disk can adapt to the inner wall of the shell without affecting the revolution of the nozzle. At the same time, the first annular channel can continuously achieve communication with the waste liquid inlet by following the rotation of the first annular disk, and can also achieve communication with the waste liquid channel through the first radial channel.

[0031] In some examples of the present invention, a compressed gas channel is defined within the nozzle, one end of the compressed gas channel extends to an end of the nozzle away from the drive assembly to form a compressed gas nozzle, and the other end extends to a side of the nozzle. A second annular disk is disposed between the nozzle and the housing, and a compressed gas docking channel is defined on the second annular disk to connect the compressed gas channel to a compressed gas inlet provided on the housing.

[0032] The purpose of such a setting is that since the compressed gas channel will rotate with the nozzle, and the compressed gas inlet needs to be relatively fixed, a compressed gas docking channel opened on the second annular disk is provided to connect the two.

[0033] In some examples of the present invention, the second annular disk is fixedly connected to the nozzle, the compressed gas docking channel includes a second annular channel opened at the outer edge of the second annular disk and extending circumferentially along the second annular disk, the second annular channel being connected to the compressed gas port, and the compressed gas docking channel further includes a second radial channel connected at one end to the second annular channel and at the other end to the compressed gas channel;

[0034] The purpose of such a setting is to connect the second annular disk to the nozzle so that the second annular disk can rotate with the nozzle, so that the second annular disk can adapt to the inner wall of the shell without affecting the revolution of the nozzle. At the same time, the second annular channel can continuously achieve communication with the compressed gas inlet as the second annular disk rotates, and can also achieve communication with the compressed gas channel through the second radial channel.
