Description

Technical Field

[0001] The present invention relates to the technical field of vertical incinerators, and particularly to a hot-wall vertical incinerator for treating acidic waste liquid. Background Art

[0002] With the rapid development of the petrochemical industry, the technology for treating sulfur-containing substances has become increasingly important. The damage of sulfides to equipment will not only reduce the equipment life, but also may reduce the product quality. Therefore, it is necessary to remove and recover sulfur in a timely manner. Due to the increasingly strict environmental protection standards, countries have higher requirements for sulfur content, which makes the sulfuric acid production technology a necessary solution. The sulfuric acid production technology can not only destroy the content of sulfides, but also promote the reaction and convert it into stable sulfate substances. Therefore, in recent years, the development of efficient and reliable sulfuric acid production technology has attracted more and more attention from researchers and the industrial community. A vertical incinerator is an environmental protection equipment for high-temperature incineration of waste gas, waste liquid, solid waste, etc., and is commonly used in medical and domestic waste, animal harmless treatment. It usually includes a waste inlet, a waste outlet, a waste crushing chamber, an incineration chamber, a smoke treatment chamber, etc. The waste crushing chamber is used to crush the waste to facilitate subsequent combustion. A burner is provided in the incineration chamber to provide the heat required for combustion. The smoke treatment chamber is used to treat the smoke generated by combustion to reduce pollutant emissions. The waste enters the incinerator from the waste inlet, is first 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 for treating acidic waste liquid is needed. The existing vertical incinerators have problems such as incomplete incineration and easy corrosion of equipment, with low combustion efficiency of organic substances in acidic waste liquid, resulting in incomplete treatment and possible residue of harmful substances.

The other end of the transport pipe two is fixedly installed with an activated carbon adsorption box. The side wall of the activated carbon adsorption box is fixedly connected to the inner wall of the side plate. A connecting pipe is fixedly installed on the other side of the activated carbon adsorption box. A rectangular plate is fixedly installed on the top of the activated carbon adsorption box. A sliding rod is slidably installed on the inner wall of the rectangular plate. One end of the sliding rod is fixedly installed with a moving block. A compression spring is fixedly installed on the side wall of the moving block. The other end of the compression spring is fixedly connected to the side wall of the cooler. The other end of the sliding rod is fixedly installed with a limiting block. The top of the activated carbon adsorption box is hingedly installed with a movable cover through a hinge.

[0010] Preferably, the inner wall of the connecting pipe is communicated with the inside of the activated carbon adsorption box, the inner wall of the activated carbon adsorption box is communicated with the inside of the second transport pipe, the inner wall of the second transport pipe is communicated with the inside of the cooler, the inner wall of the cooler is communicated with the inside of the first transport pipe, and the inner wall of the first transport pipe is communicated with the inside of the incinerator. The tail gas generated during the combustion process will be transported through the first transport pipe to the inner wall of the cooler, and the cooler will initially cool down the tail gas. Subsequently, it will be transported again through the second transport pipe to the inner wall of the activated carbon adsorption box. The activated carbon on the inner wall of the activated carbon adsorption box will adsorb some impurities and trace harmful substances in the tail gas. The treated tail gas will be discharged through the connecting pipe.

The inner wall of the flame spraying pipe is communicated with the inside of the output pipe. The inner wall of the output pipe is communicated with the inside of the burner body. By operating the locking screw, the position of the burner body can be stabilized. When the burner body is turned on, a flame will be generated inside and blown to the inner wall of the output pipe, and then transported to the inner wall of the flame spraying pipe and ejected from the opening of the flame spraying pipe to effectively incinerate the waste liquid.

[0013] Preferably, the number of the backing plates is four. The four backing plates have the same shape and size and are respectively fixedly installed at the bottom of the incinerator. The backing plates can support the overall position of the device.

[0014] The present invention provides a hot-wall vertical incinerator for treating acidic waste liquid. It has the following beneficial effects: (1) By operating to pull the position of the handle, the handle drives the position of the sealing cover to flip. Subsequently, the waste liquid can be added to the inner wall of the feed pipe. The waste liquid enters the inner wall of the incinerator through the feed pipe. First, it contacts the inner wall of the deflector plate, and then it contacts the inner wall of the spiral blade. After sliding spirally on the surface of the spiral blade, it drops onto the inner wall of the bottom plate. The waste liquid is evenly sprinkled into the incinerator through the through-hole plate on the inner wall of the bottom plate, promoting the contact area between the waste liquid and the flame and further improving the combustion efficiency. This solves the problems existing in the existing vertical incinerator, such as incomplete incineration and easy corrosion of equipment, and the low combustion efficiency of organic matter in acidic waste liquid, resulting in incomplete treatment and possible residue of harmful substances.

[0015] (2) By using the locking screw, the operator can stabilize the position of the burner body. When the burner body is turned on, flames will be generated inside and transported to the inner wall of the output pipe, and then to the inner wall of the spout pipe and ejected from the opening of the spout pipe, effectively burning the waste liquid.

[0016] (3) When the operator needs to replace the activated carbon inside the activated carbon adsorption box, the position of the moving block can be pulled first. The moving block drives the sliding rod to slide on the inner wall of the rectangular plate. At this time, one end of the compression spring is stretched. The sliding rod drives 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 position of the pulling block can be directly pulled. The pulling block further flips the position of the movable cover, prompting the position of the movable cover to open, facilitating the operator to replace the activated carbon inside.

[0017] (4) During the combustion process, the tail gas generated will be transported to the inner wall of the cooler through the first transport pipe. The cooler preliminarily cools the tail gas. Subsequently, it is transported to the inner wall of the activated carbon adsorption box again through the second transport pipe. The activated carbon on the inner wall of the activated carbon adsorption box adsorbs some impurities and trace harmful substances in the tail gas. The treated tail gas will be discharged through the connecting pipe, enabling the rapid treatment of the tail gas. Brief Description of the Drawings
