Abstract

The invention discloses a combustible gas control type efficient garbage processing system comprising a furnace body used for processing garbage and a control device. A feeding inlet is formed in the top of the furnace body. Pipe rows are arranged in the furnace body. An air exhaust outlet is formed in the furnace body. A detecting device used for detecting the concentration of combustible gas in real time is arranged at the air exhaust outlet. A heating device is arranged in the position, above the pipe rows, inside the furnace body. The control device is connected with the heating device to be used for controlling the heating amount of the heating device and further connected with the detecting device to be used for obtaining detecting data of the detecting device, comparing the obtained detecting data F0 with a preset threshold F1 and controlling motions of the heating device according to a comparison result. The garbage processing system can control the temperature according to the reaction situation of a reduction layer generated by combusting of the garbage so as to guarantee the fact that the thicknesses of all reaction layers are relatively stable, and accordingly the garbage in a furnace is processed continuously and stably.

Example Embodiment

[0017] Below, the technical solution of the present invention will be described in detail through specific examples.
[0018] like figure 1 as shown, figure 1 It is a structural schematic diagram of a combustible gas-controlled garbage high-efficiency treatment system proposed by the present invention.
[0019] refer to figure 1 , a combustible gas-controlled high-efficiency garbage treatment system proposed in an embodiment of the present invention, including: a furnace body 1 for treating garbage, and a control device, wherein:
[0020] The top of the furnace body 1 is provided with a feeding port 101, and the side near the bottom of the furnace body 1 is provided with a tube row 2, and a distance is reserved between the tube row 2 and the bottom of the furnace body 1 to form a slagging chamber , the pipe row 2 is connected with a blast device (not shown in the figure), and the pipe row 2 is provided with an air distribution hole communicated with the interior of the furnace body 1; The exhaust port 102 connected to the cavity is used to discharge the gas in the furnace. The exhaust port 102 is equipped with a detection device 3 for real-time detection of the combustible gas concentration; The heating device 4 includes a plurality of heating tubes, each heating tube extends horizontally, and the heating tubes are arranged in layers from the tube row 2 to the feeding port 101 .
[0021] The control device is connected with the heating device 4 for controlling the heating amount of the heating device 4; the control device is also connected with the detection device 3 for obtaining the detection data of the detection device 3 and comparing the obtained detection data F0 with the preset threshold F1 For comparison, when the result of the comparison is that the acquired detection data F0 is less than the threshold value F1, the control device controls the heating device 4 to perform heating work until the acquired detection data is equal to the threshold value; and the control device compares the acquired detection data F0 with the threshold value F1 Among them, when the acquired detection data F0 is smaller than the threshold F1, the greater the difference between the detection data F0 and the threshold F1, the greater the heat generated by the heating device 4 per unit time, so as to shorten the heating time.
[0022] In the present invention, the pipe row 2 is arranged inside the furnace body 1. When processing garbage, a layer of fuel layer is laid on the top of the pipe row 2 and ignited, and the garbage is poured into the furnace body from the feeding port 101 after burning. The garbage is supported, and the lit fuel layer is used to dry and dry the garbage above it until it is ignited; by setting the heating device 4 above the pipe row 2, the heating device 4 is used to assist in heating the reduction layer above the oxide layer ; By setting the inspection device at the exhaust port 102, the combustible gas content in the exhaust gas is detected by the inspection device. At the same time, a control device is provided, and the control device is connected to the heating device 4 and the detection device 3 respectively, and the detection data of the detection device 3 is obtained by the control device and compared with the preset threshold value. When the acquired detection data is less than the threshold value, it indicates that the content of combustible gas in the exhaust gas is low, which means that the reduction layer temperature is insufficient and the pyrolysis efficiency is low. At this time, the control device controls the heating device 4 to perform auxiliary heating to ensure the reduction The temperature of the layer can meet the temperature requirements during the pyrolysis of garbage, and avoid the problem of extinguishing due to insufficient temperature of the oxide layer in the furnace due to excessive absorption of heat in the furnace. In addition, by controlling the temperature of the reduction layer, when the temperature of the reduction layer is relatively stable, its thickness can be ensured to be relatively stable, so that the thickness of the oxide layer below the reduction layer, and the carbonization layer and drying layer above the reduction layer are uniform. Relatively stable, so as to ensure the continuity and stability of the waste treatment in the furnace.
[0023] In addition, in this embodiment, an auxiliary heating device 5 is provided in the furnace body 1 and located on the side of the heating device 4 close to the feeding port 101, and a sensor is provided in the furnace body 1 and located on the side close to the feeding port 101. For detecting the humidity of the garbage; the auxiliary heating device 5 and the sensor are respectively connected with the control device, and the control device is used to obtain the detection data F01 of the sensor and compare the obtained detection data F01 with the threshold F2, when the comparison As a result, when F01 is greater than the threshold F2, the control device controls the auxiliary heating device 5 to heat, so as to ensure that the dry state of the garbage in the area meets the expected requirements and avoid causing the working pressure of the heating device 4 .
[0024] In addition, in this embodiment, the cross-sectional shape of the heating pipe is an equilateral triangle with the apex facing the feeding port 101, so that the apex in the heating pipe can be used to crush the garbage so that the garbage above the heating device 4 can pass through smoothly.
[0025] It can be known from the above that the high-efficiency treatment system of combustible gas control type garbage proposed by the present invention can control the temperature according to the reaction conditions of the reducing layer formed when the garbage is burned, so as to ensure that the thickness of each reaction layer is relatively stable, so that the furnace Continuity and stability of internal waste disposal.
[0026] The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, any person familiar with the technical field within the technical scope disclosed in the present invention, according to the technical solution of the present invention Any equivalent replacement or change of the inventive concepts thereof shall fall within the protection scope of the present invention.
