Description

Technical Field

[0001] This invention relates to the field of vertical incinerator technology, specifically a hot-wall vertical incinerator for treating acidic wastewater. Background Technology

[0002] With the rapid development of the petrochemical industry, technologies for treating sulfur-containing substances have become increasingly important. Sulfides not only damage equipment, reducing its lifespan, but can also reduce product quality, necessitating timely removal and recycling. Due to increasingly stringent environmental standards, countries have imposed higher requirements on sulfur content, making acid production technology a necessary solution. Acid production technology not only breaks down sulfides but also promotes the reaction, converting them into stable sulfates. Therefore, in recent years, the development of efficient and reliable acid production technology has received increasing attention from researchers and industry. Vertical incinerators are environmental protection equipment used for high-temperature incineration of waste gas, waste liquid, and solid waste. They are commonly used in the treatment of medical and domestic waste and animal waste. They typically include a waste inlet, a waste outlet, a waste crushing chamber, an incineration chamber, and a fume treatment chamber. The waste crushing chamber is used to crush the waste to facilitate subsequent combustion. The incineration chamber is equipped with a burner to provide the heat required for combustion. The fume treatment chamber is used to treat the fumes generated during combustion to reduce pollutant emissions. Waste enters the incinerator from the waste inlet, is crushed in the waste crushing chamber, and then enters the incineration chamber for combustion. The residue after combustion is discharged from the waste outlet. Therefore, a hot-wall vertical incinerator is needed to treat acidic waste liquid. Existing vertical incinerators have problems such as incomplete combustion and easy corrosion of equipment. They also have low combustion efficiency for organic matter in acidic waste liquids, resulting in incomplete treatment and potential residues of harmful substances. Summary of the Invention

[0013] Preferably, there are four pads, all of the same shape and size, and the four pads are fixedly installed at the bottom of the incinerator body, so as to support the position of the entire device.

[0014] This invention provides a hot-wall vertical incinerator for treating acidic wastewater, which has the following advantages: (1) The present invention allows the handle to be pulled to rotate the sealing cover, allowing waste liquid to be added to the inner wall of the feed pipe. The waste liquid enters the inner wall of the incinerator body through the feed pipe, first contacting the inner wall of the guide plate, and then contacting the inner wall of the spiral blade. After spiraling through the surface of the spiral blade, it falls to the inner wall of the bottom plate. The waste liquid is evenly sprinkled into the interior of the incinerator body through the through-hole plate on the inner wall of the bottom plate, which increases the contact area between the waste liquid and the flame, further improving the combustion efficiency. This solves the problems of incomplete combustion, easy corrosion of equipment, low combustion efficiency of organic matter in acidic waste liquid, incomplete treatment, and possible harmful substance residues in existing vertical incinerator bodies.

[0015] (2) The present invention allows the operator to stabilize the position of the burner body by using a locking screw. When the burner body is turned on, a flame is generated inside and blown to the inner wall of the output pipe, and then to the inner wall of the flame tube, and sprayed out from the opening of the flame tube, effectively burning the waste liquid.

[0016] (3) When the operator needs to replace the activated carbon on the inner wall of the activated carbon adsorption box, the operator can first pull the position of the moving block. The moving block will drive the slide rod to slide on the inner wall of the rectangular plate. At this time, one end of the compression spring will be stretched. The slide rod will drive the limiting block to slide on the top of the activated carbon adsorption box. When the bottom of the limiting block does not contact the top of the movable cover, the operator can directly pull the position of the pulling block. The pulling block will further flip the position of the movable cover, causing the movable cover to open, making it convenient for the operator to replace the activated carbon inside.

[0017] (4) In this invention, the exhaust gas generated during the combustion process is transported to the inner wall of the cooler through transport pipe one. The cooler performs preliminary cooling of the exhaust gas. Then, it is transported to the inner wall of the activated carbon adsorption box through transport pipe two. The activated carbon on the inner wall of the activated carbon adsorption box adsorbs some impurities and trace harmful substances in the exhaust gas. The treated exhaust gas is discharged through the connecting pipe, which can realize the work of quickly treating exhaust gas. Attached Figure Description

The waste liquid is evenly sprinkled into the interior of the incinerator body 1 through the through-hole plate 416 on the inner wall of the bottom plate 415, which increases the contact area between the waste liquid and the flame and further improves the combustion efficiency.

[0030] Example 2: Based on Example 1, a preferred embodiment of the hot-wall vertical incinerator for treating acidic wastewater provided by the present invention is as follows: Figures 1 to 6 As shown: The processing mechanism 42 includes a side plate 422, which is fixedly installed on the side wall of the incinerator body 1.
