Description

Waste incineration equipment

Technical Field

The utility model relates to a refuse handling installation field especially relates to a waste incineration equipment.

Background

In the meantime, the garbage in remote scenic spots or off-line islands is difficult to clear and transport, and is usually buried or burned in the open air, which causes great pollution to the ecological environment. Therefore, there is a need for a waste incineration device that can incinerate waste under closed conditions on site.

The existing garbage incineration device generally comprises a main combustion chamber and a flue gas secondary combustion chamber. The main combustion chamber is used for placing garbage and is forced to ventilate inwards through a fan so as to provide oxygen required by garbage combustion. The incompletely combusted smoke enters a second combustion chamber, and the second combustion chamber is provided with another independent fan for forced ventilation so as to lift oxygen for the sufficient combustion of the smoke. However, the air volume control of the second combustion chamber of the incineration equipment is complicated. Because the garbage amount and the garbage composition of the main combustion chamber are unstable, the content of the generated incompletely combusted smoke is unstable, and the ventilation quantity of the secondary combustion chamber is difficult to change along with the change of the smoke content. If the smoke supply of the secondary combustion chamber is less, the smoke cannot be completely combusted in the secondary combustion chamber; if the smoke supply of the secondary combustion chamber is excessive, the combustion temperature of the secondary combustion chamber can be reduced, the pollutant degradation temperature can not be reached, and even the flameout possibility exists.

In order to solve the problem, a gas analyzer needs to be installed at a chimney at the outlet of the secondary combustion chamber so as to control the air supply amount of a fan of the secondary combustion chamber. The equipment has more control elements and sensing elements and high manufacturing cost. And, if the individual parts are damaged, professional personnel are required to get on the door for maintenance. Therefore, such incineration plants are not suitable for operation in remote areas.

Therefore, a new type of waste incineration equipment is needed, which is simple to control, has a small number of elements and can play an important role in an off-line scene.

In addition, the first combustion chamber 300 and the second combustion chamber 100 are cylindrical, and the inner diameter of the second combustion chamber 100 is smaller than that of the first combustion chamber 300, so that the part covered by the cover 104 is the top part space of the first combustion chamber 300, and the smoke will be concentrated in the hollow part to enter the second combustion chamber 100.

Furthermore, in order to facilitate the garbage loading into the first combustion chamber 300, the cover 104 has a hinge connected to the edge of the first combustion chamber 300, and the second combustion chamber 100 is fixed on the mounting end surface of the cover 104 (the mounting end surface is the end surface far away from the first combustion chamber 300), and a handle 107 is further disposed on the mounting end surface, the fixed end of the handle 107 is fixedly connected to the mounting end surface, and the free end extends in the direction far away from the first combustion chamber 300.

When a user holds the armrest 400 and presses down the armrest 400, the armrest 400 rotates around a fixed position (the fixed position is not fixed in space, but is fixed relative to the support), when the armrest 400 rotates to be almost horizontal, the support members contact the ground, the first combustion chamber 300 and the second combustion chamber 100 are in a lying state together with the armrest 400, and then the cover 104 is hinged to be opened, so that the user can horizontally transport the incinerated garbage out, thereby facilitating the disposal.

The ash receiving plate 402 is located close to the cover 104, when the first combustion chamber 300 is lying, the ash receiving plate 402 is also in a lying state, and due to the close proximity to the first combustion chamber 300 (preferably closer to the opening of the first combustion chamber 300), when the user can carry the garbage in the first combustion chamber 300 out by using a shovel, the garbage will be scraped onto the ash receiving plate 402, and the ash receiving plate 402 receives the burning remainder as an intermediate transfer platform. Meanwhile, the rollers are arranged at the fixed positions of the handrail 400 and the supporting piece, so that a user can conveniently move the whole garbage incineration device, and at the edge of the supporting piece, the direction far away from the handrail 400 (or the rollers) extends to form the support leg 401, the support leg 401 is arc-shaped and gradually extends to the ground, and the height of the support leg 401 in the vertical direction is basically equal to the radius of the roller, so that when the garbage incineration device is vertically placed, the supporting piece is in a horizontal state, and the first combustion chamber 300 and the second combustion chamber 100 are correspondingly in a standard vertical state to prevent dumping.

It is further preferred that the blower 204 is fixed to the handle 400 and the inner chamber 200 of the blower 204 is close to the first combustion chamber 300, and when the combustion process is performed in the first combustion chamber 300, heat is radiated to the outside, and this heat is absorbed by the inner chamber 200 of the blower 204 to heat the air entering the inner chamber 200 of the blower 204, so that the air entering the second combustion chamber 100 is hot air without extinguishing the combustion process in the first combustion chamber 300 and the second combustion chamber 100.

In yet another preferred embodiment, the positive pitch angle is between 1 ° and 60 ° depending on the time the user has air trapped in the second combustion chamber 100 (the smaller the angle, the longer the residence time). While the through-holes are arranged concentrically with the second combustion chamber 100 to facilitate both separation and contact of the flue gases with the air entering the second combustion chamber 100, the flame bundles in the first combustion chamber 300 being concentrated in the central region.

Referring to fig. 5 to 6, the use of the waste incineration apparatus according to a preferred embodiment of the present invention will be described. Before use, the throttling device 203 in front of the air outlet 202 is opened to the maximum, so that the air outlet amount is maximum, and the air outlet 201 has the minimum air outlet; pulling the handle 107, opening the sealing cover 104 and throwing the materials; manually igniting the material; the blower 204 is turned on, the blower 204 injects cold air into the inner cavity 200, and the inner cavity 200 heats the cold air into hot air after receiving heat emitted from the outer wall of the first combustion chamber 300. At this time, a part of the hot air is discharged through the air outlet 202, and a small amount of the hot air is blown out from the air outlet 201 and enters the gas injection pipe 105 through the flexible snorkel 106. The hot air flows in a spiral flow in the second combustion chamber 100 in a tangential direction of the gas injection pipe 105, moving downward. First, the hot air encounters the unburned hot flue gases emerging from the first combustion chamber 300. The unburned hot flue gas is disturbed in the air flow by the spoiler disc 102, is sufficiently mixed with the hot air moving downward, and is combusted in the second combustion chamber 100. Then, the unreacted hot air carries the residual oxygen, and continues to move downwards along the hollow-out part around the inner walls of the turbulence plate 102 and the second combustion chamber 100 in a spiral shape, so as to form a spiral air field in the first combustion chamber 300, and provide the oxygen required by combustion for the material. When the smoke starts to exist at the top of the second combustion chamber 100, it indicates that the material inside the first combustion chamber 300 reaches the sufficient pyrolysis temperature and the flammable smoke continuously gushes out, however, the air supply amount of the second combustion chamber 100 is insufficient. At this time, the throttling device 203 in front of the air outlet 202 is opened to the minimum, so that the air outlet amount is the minimum, and the air outlet 201 exhausts air to the maximum. Sufficient oxygen is provided for the combustion of the unburned flue gas in the second combustion chamber 100, at which time the macroscopic view of the flue gas disappears. During the reaction process, the handle 107 can be pulled at any time to open the cover 104 and put in the material. It should be noted that before the cover 104 is opened, the air volume of the air outlet 202 needs to be adjusted to be larger, so that the air volume is decreased, so as to prevent the burning fly ash from being blown into the environment by strong wind; after the reaction is completed, when the equipment is lowered to normal temperature, the equipment can be placed horizontally, the cover 104 is opened, ash in the barrel is scraped out by an iron shovel, falls onto the ash receiving plate 402, and is scraped into a container from the ash receiving plate 402 and is transported away, so that the ash is properly buried and disposed.

With the above configuration, the second combustion chamber is made of a hollow metal tube, and the lower bottom surface of the second combustion chamber is welded around a sheet of the cap, so that the second combustion chamber and the cap become an integral body. And a metal net is arranged on the top surface of the second combustion chamber and can block sparks blown out by wind. An annular cover body is welded at the position, close to the upper part, of the middle part of the second combustion chamber. The circular through hole of the annular cover body is concentric with the second combustion chamber, and the outer edge of the annular cover body is welded on the inner wall of the second combustion chamber. The existence of the annular cover body can ensure that the unburned flue gas is fully mixed with the injected air, thereby achieving the purpose of full combustion. And a turbulence disc is concentrically welded at the bottom of the second combustion chamber through a thin and narrow metal sheet. The turbulence plate and the interior of the second combustion chamber form a hollow-out part (the hollow-out part is used as an annular air passage). The annular air passage can enable oxygen which is not completely reacted in the second combustion chamber to enter the first combustion chamber in a spiral shape to generate combustion reaction with materials. Because of the action of the spiral gas field, the flame in the first combustion chamber is concentrated at the central position, and the generated high-temperature flue gas rises and collides with the turbulence plate. The high-temperature flue gas is extruded into the second combustion chamber from the annular air passage on the outer side of the turbulence disc to form turbulence. The unburnt high-temperature flue gas turbulence is mixed with part of fresh air spirally sprayed from the gas injection pipe intensely to generate combustion reaction. In the second combustion chamber, a cavity formed by the upper annular cover body and the bottom turbulence plate is the second combustion chamber, and a gas injection pipe is welded at the top of the second combustion chamber and below the annular cover body along the tangential direction of the circle of the second combustion chamber. The gas injection pipe can present tiny contained angle (1 ~ 45 degrees) with the horizontal direction for the air of injection can downward spiral motion, increases the mixture of air and unburned high temperature flue gas on the one hand, promotes the reburning of high temperature flue gas, and on the other hand can make the hot-air that has not been reacted can reach first combustion chamber below better, produces combustion reaction with the material. The blower blows cold air into the inner cavity, the inner cavity is close to the first combustion chamber, and the heat radiation of the first combustion chamber heats the inner cavity to indirectly heat the cold air inside. Part of the cold air is exhausted from the inner cavity through an air outlet, and the air displacement of the air outlet is adjusted to be opened and closed by a throttling device to control the flow. The larger the opening of the throttling equipment is, the more the air flows out of the air outlet, so that the air inlet amount of the air outlet is reduced, and the combustion rate is reduced; the smaller the opening degree of the throttling equipment is, the less the air quantity flowing out of the air leakage opening is, the more the air inlet quantity of the air outlet is caused, and the combustion rate is improved. The air outlet is connected with an air injection pipe through a metal heat-resisting hose air pipe. The flexible vent pipe is convenient to install, and when the sealing cover is turned over, the hose can keep the mobility, so that the phenomenon of equipment interference is avoided.

It should be noted that the embodiments of the present invention have better practicability and are not intended to limit the present invention in any way, and any person skilled in the art may change or modify the technical contents disclosed above to equivalent effective embodiments, but all the modifications or equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
