The embodiments of the present invention are described below by way of specific embodiments, and those skilled in the art can readily appreciate other advantages and functions of the present invention from the disclosure of the present disclosure. The present invention may also be implemented or applied by other different embodiments, and the details in the present specification may also be based on different viewpoints and applications, and may be carried out without departing from the spirit of the present creation. Modifications and changes.

Please refer to Figure 1 for a schematic diagram of the operation of the sludge disposal equipment of this creation. As shown in the figure, the sludge waste treatment equipment 1 of the present invention is used to treat sludge waste 100, such as textile sludge or pulp sludge, which contains organic compounds such as hydrocarbons, vulcanization. Hydrogen, etc., so there is a considerable taste or bad smell, so the sludge waste treatment equipment 1 proposed by the present invention is used in the treatment of such sludge, and the waste gas and waste water generated are burned to reduce the addition of waste gas and waste water. The cost of processing the system.

The sludge waste treatment equipment 1 includes a feed hopper 11, a dehydrator 12, a dryer 13 and a combustion boiler 14, wherein a line 101, a dehydrator 12 and a combustion boiler 14 are interposed between the dehydrator 12 and the dryer 13. There is a line 102 between the line, and between the dryer 13 and the combustion boiler 14.

The feed hopper 11 is used for the sludge waste 100 to enter, and the dewatering machine 12 is connected to the feed hopper 11, that is, the sludge waste 100 is sent to the dewatering machine 12 after passing through the feed hopper 11, and the dewatering machine 12 is used to perform the sewage. The sludge waste 100 is subjected to a dehydration process to separate the sludge waste 100 into solid sludge and wastewater. Generally, the sludge waste 100 has a moisture content of about 90% to 95%, but after dehydration by the dehydrator 12 The moisture content of the sludge waste 100 can be reduced to less than 65%. The sludge waste 100 is separated into solid sludge and waste water after being dehydrated, and the solid sludge is sent to the dryer 13 by the line 101, and the waste water is sent to the combustion boiler 14 through the line 102.

The dryer 13 is connected to a dehydrator 12 for performing a drying process of the solid sludge, and the solid sludge is dried to form a powdery sludge and generate exhaust gas, usually the dryer 13 Solid sludge with a moisture content of about 65% Dry to a moisture content of about 15%. More specifically, the dryer 13 may be a rotary kiln with a scraper, which can provide rotary drying and use a scraper to reduce the solid sludge, and the solid sludge can be powdered after being dried and miniaturized. The sludge and waste gas are sent to the combustion boiler 14 via line 103.

The combustion boiler 14 is connected to a dehydrator 12 and a dryer 13, which includes a steam boiler 141 and a first combustion chamber 142, and introduces powdered sludge, waste water and exhaust gas into the first combustion chamber 142 for the first combustion. The process, while the thermal energy generated by the first combustion chamber 142 can provide operation of the steam boiler 141. In a specific implementation, the first combustion chamber 142 and the steam boiler 141 are disposed together, that is, the first combustion chamber 142 burns sludge, exhaust gas, waste water, and the like underneath, and the upper steam boiler 141 can generate steam.

In order to achieve the purpose of the present creation, that is, to reduce the content of odorous substances in the waste water and the exhaust gas itself, the waste water and the exhaust gas are introduced into the first combustion chamber 142 for combustion. More specifically, the powdered sludge is the main fuel of the first combustion chamber 142, and the waste water and the exhaust gas are introduced into the first combustion chamber 142 for combustion to destroy the structure of the odorous substance, except that the first combustion chamber 142 can be increased. In addition to the thermal energy, the odorous material in the waste water and the exhaust gas can be eliminated by the first combustion process performed by the first combustion chamber 142.

Compared with the prior art, the traditional sludge waste treatment method only burns the solid sludge after dewatering and drying, and additional treatment equipment is needed for the waste water and waste gas generated during the dehydration and drying stages. The treatment is carried out, so the cost is high, and the waste water and the exhaust gas contain organic compounds, so the odor is not easy to handle or costs more. On the contrary, this creation proposes to introduce waste water and waste gas into the combustion chamber for combustion without any additional direct The waste water and waste gas treatment equipment are treated to reduce the cost, and the organic compounds in the waste water and the exhaust gas can also be removed by combustion, so that the occurrence of odor is also improved.

Please refer to Fig. 2 for a schematic diagram showing the operation of another embodiment of the sludge waste disposal apparatus of the present invention. In order to make the sludge waste and the waste water and waste gas produced by it more complete in combustion, the author also proposes that the sludge waste and waste water can be pre-treated before combustion, as shown in the figure, the sludge waste treatment equipment 1 The feed hopper 11, the dehydrator 12, the dryer 13 and the combustion boiler 14 are the same as those described in the first embodiment, and therefore will not be described again. In the present embodiment, the sludge waste treatment device 1 further includes a coarse crusher 15, The fine crusher 16 and the atomizer 17.

In order to make it easier to burn sludge waste, it can be refined in advance, so this creation proposes to perform the crushing process of sludge waste before drying. The coarse crusher 15 is disposed between the dehydrator 12 and the dryer 13, and can be used to crush the solid sludge to make the solid sludge become refined sludge. In detail, after the dewatering machine 12 dehydrates the sludge waste, the solid sludge is sent to the coarse crusher 15 through the pipeline 104, and the coarse crusher 15 can crush the solid sludge for the first time to make it The small refined sludge is sent to the fine crusher 16 through line 105.

The fine crusher 16 is disposed between the coarse crusher 15 and the dryer 13, and is used to crush the fine sludge sent from the coarse crusher 15 so that the refined sludge becomes a fine sand sludge. That is, the fine crusher 16 crushes the fine sludge generated by the crusher 15 to make the sludge waste into a fine sand, and the fine sand sludge is sent to the line through the line 106. Dry machine 13, this It also contributes to subsequent drying and burning.

Taking the plate-and-frame dewatering machine as an example, after the sludge waste is dehydrated, a block of 1 meter cubic and 5 cm thick will be produced. After falling from a height, it will be in the shape of a piece of different size for subsequent drying. The combustion is influential; in addition, the traditional sludge waste will be directly dried and granulated after dewatering. Since the sludge forms granules of different sizes, this will increase the operation capacity of the drying equipment. Therefore, this creation proposes to perform the crushing process before drying, which will facilitate subsequent drying and burning. It should be noted that although the present invention proposes a coarse crusher 15 and a fine crusher 16 to perform the crushing of the solid sludge, it is possible to set only one of them, or to add more crushers, which may be changed according to actual needs.

In addition, in order to make the wastewater flammable in the first combustion chamber 142, an atomizer 17 may be disposed between the dehydrator 12 and the first combustion chamber 142 to atomize the wastewater, so that the first combustion chamber 142 can more easily treat the wastewater. Burning. Specifically, the waste water generated after the dewatering machine 12 is dehydrated can be sent to the atomizer 17 through the pipeline 102. The vaporization temperature of the wastewater is about 160-170 ° C, so the wastewater is first atomized through the atomizer 17 and enters the combustion. After the chamber, the water can be evaporated, while other organic compounds can be burned.

Please refer to Fig. 3 for a schematic diagram showing the operation of still another embodiment of the sludge disposal apparatus of the present invention. Although this work proposes to burn waste water and waste gas to reduce costs and reduce organic compounds in waste water and waste gas, in order to avoid incomplete combustion or residual harmful substances after combustion, this creation proposes the concept of second combustion. . As shown in the figure, the hopper 11, the dehydrator 12, the dryer 13, and the combustion boiler 14 of the sludge waste treatment apparatus 1 are the same as those described in FIG. 1, and therefore will not be described again. In the present embodiment, The sludge waste treatment plant 1 further includes a second combustion chamber 18.

The second combustion chamber 18 is a first combustion chamber 142 that is coupled to the combustion boiler 14 for performing a second combustion sequence on the product produced when the first combustion chamber 142 is combusted. Since the sludge, the waste water, and the exhaust gas generate gas after combustion, there may be dioxin, so in order to reduce the harmful substances of the burned gas, the gas generated when the first combustion chamber 142 is burned is transmitted to the first through the pipeline 107. The second combustion chamber 18, the second combustion chamber 18 and the first combustion chamber 142 are different combustion chambers, and the incompletely combusted material is re-burned after the first combustion, so only the gas or a few particles are left after the second combustion. An object (for example, a suspended solid of about 10 μm). In a specific implementation, the combustion temperature of the second combustion chamber 18 is at least 1000 ° C or higher, preferably about 1600 ° C, which is beneficial for burning heavy metals or dioxin and other harmful substances.

Please refer to Figure 4 for a schematic diagram showing the combination of the sludge disposal equipment of this creation with other equipment. The present invention proposes that when the sludge waste is burned, the waste water and the waste gas generated by the same are burned together. In this embodiment, the combination of the sludge waste treatment equipment 1 of the present invention and the peripheral equipment is mainly described. As shown in the figure, the feed hopper 11, the dehydrator 12, the dryer 13, and the combustion boiler 14 of the sludge waste treatment apparatus 1 are the same as those described in Fig. 1, and therefore will not be described again.

As previously mentioned, the first combustion chamber 142 of the combustion boiler 14 is used to combust sludge, waste water and waste gas, and the heat energy generated by the first combustion chamber 142 can be operated by the steam boiler 141, that is, the steam boiler 141 can generate steam for supply. Execution of other equipment, for example, vapor of steam boiler 141 may be transmitted to external steam generator 91 through line 108, thereby driving the steam generator 91 Executing the power generation process, the electric energy generated by the steam generator 91 will be available for the electricity used by the sludge waste treatment equipment 1, and may also be used for other power consumption of the entire sludge treatment plant, so that the heat energy of the combustion process can be generated. The added value is not only to dispose of waste, but also to make good use of energy.

In addition, although the present proposal proposes to pass two combustion procedures to reduce the odor or harmful substances of the burned gas, it is still possible to provide a control for connecting the second combustion chamber 18 outside the sludge waste treatment device 1 as needed. The apparatus 90, the gas generated after the combustion of the second combustion chamber 18, can be transmitted to the external prevention device 90 through the line 109. In short, the second combustion chamber 18 can reduce the odor or harmful substances of the gas, but must be detected before the gas is discharged. If necessary, if the gas contains unburned sulfides, nitrides, etc., it can be treated through the control device 90 to prevent the exhaust gas from affecting the environment. However, the control device 90 is still subject to the combustion of the first combustion chamber 142 and the second combustion chamber 18 to determine whether it is necessary or not, and is not a necessary device.

In addition, the pipelines 101~109 mentioned in this creation may change depending on the contents of the delivery, that is, if the waste water or waste gas is delivered, it may have an anti-corrosion function. If the content is high temperature, the high-temperature pipeline must be used. This is well known to those skilled in the art and will not be explained one by one.

In summary, the sludge waste treatment equipment of the present invention proposes a treatment method of sludge waste, in particular, introducing waste water and waste gas into a combustion boiler to perform combustion, thereby making the content of the odorous substance contained in the waste water and the waste gas. Reduced, in addition, through the secondary combustion method, the odor or harmful substances of the burned gas are reduced, so it is not necessary to use the waste liquid and the exhaust gas treatment system to treat the waste water and the waste gas as in the prior art, therefore, the creation Sludge waste Treatment equipment can reduce the cost of sludge waste disposal, while also allowing sludge waste to be properly located and reducing the impact on the surrounding environment and residents.

The above embodiments are intended to illustrate the principles of the present invention and its effects, and are not intended to limit the present invention. Anyone who is familiar with the art may modify the above embodiments without departing from the spirit and scope of the creation. Therefore, the scope of protection of this creation should be as listed in the scope of patent application.
