Abstract
Description
Technical Field
[0001] The utility model relates to the field of gas production equipment, in particular to a novel energy-saving water jacket. Background Art
[0002] A gasifier is a production equipment that converts coal into combustible gas - coal gas (mainly composed of CO, H2, CH4, etc.). Its working principle is to screen the coal that meets the gasification process indicators and add it into the gasifier through a stoker. A mixture of self-produced steam and air is blown into the bottom of the furnace as a gasifying agent. The coal undergoes physical and chemical reactions in the furnace to generate combustible gas for users to use.
[0003] The water jacket is one of the important parts in the gasifier. The purpose of setting the water jacket is to use the cold wall effect of the water jacket to reduce the temperature of the coal near the jacket wall and prevent the coal from overheating and hanging in the furnace. Figure 1 As shown, a circular cylinder is installed outside the furnace body. Water flows between the furnace body and the circular cylinder to cool the furnace body. However, this type of water jacket removes too much heat during the gas production process, resulting in overcooling. This not only reduces gas production efficiency, but also causes excessive heat consumption, resulting in large amounts of steam production in the water jacket, which greatly increases cooling water consumption. In addition, overcooling can also lead to incomplete combustion of coal in the inner and outer ring areas of the furnace body, increasing the coal content in the slag, resulting in excessive energy consumption.
[0004] To this end, the applicant applied for a patent for "A thermal insulation water jacket for a gas generator, application number 2023209907625" on April 27, 2023. Figure 2 However, during the use of this device, there is still a problem that the water jacket takes away too much heat. To this end, our company has proposed a new energy-saving water jacket. Summary of the Invention
[0005] The purpose of the utility model is to provide a novel energy-saving water jacket to ensure appropriate cooling of the furnace body.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A new energy-saving water jacket comprises a cylinder, wherein an upper header, a jacket pipe and a lower header are respectively arranged on the outside of the cylinder from top to bottom, the upper header is provided with a water outlet pipe section, the lower header is provided with a water inlet pipe section, a flow channel for cooling liquid to flow is formed between the jacket pipe and the cylinder, and the jacket pipe is provided with multiple grooves for reducing the flow channel capacity.
[0008] Preferably, a sealing plate for sealing the opening of the jacket tube is provided at the opening of the jacket tube.
[0009] Preferably, the upper and lower ends of the slot have arc surfaces for mitigating liquid impact.
[0010] Preferably, the sealing plate includes a first sealing plate for sealing the left and right openings of the jacket pipe slot and a second sealing plate for sealing the upper and lower openings of the jacket pipe slot.
[0011] Preferably, the jacket tube is a plurality of semicircular tubes, and the slots are provided on the semicircular tubes.
[0012] Preferably, the jacket tube is a cylinder surrounding the cylinder body, and the slots are provided on the cylinder.
[0013] The beneficial effects of the utility model are:

For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted from the accompanying drawings. DETAILED DESCRIPTION
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] Example 1
[0025] like Figure 3 and Figure 4 As shown, a new energy-saving water jacket comprises a cylinder 1. An upper header 2, a jacket pipe 4 and a lower header 3 are respectively provided on the outside of the cylinder 1 from top to bottom. The jacket pipe 4 is a plurality of semicircular tubes uniformly distributed on the outside of the cylinder 1. A water outlet pipe section 21 is provided on the upper header 2, and a water inlet pipe section 31 is provided on the lower header 3. A flow channel 41 for cooling water to flow is formed between the jacket pipe 4 and the cylinder 1. A groove 5 for reducing the capacity of the flow channel 41 is provided on the semicircular tube. A sealing plate for sealing the opening of the jacket pipe is provided at the opening of the jacket pipe (the opening is the opening formed by the groove on the surface of the semicircular tube). During use, cooling water enters the flow channel 41 from the water inlet pipe section 31, fills the flow channel 41 and then flows out from the water outlet pipe section 21. The cooling water circulates along the water inlet pipe section 31, the flow channel 41 and the water outlet pipe section 21 to cool the cylinder 1, ensuring that the coal inside it burns to produce coal gas. In order to avoid excessive cooling of the cylinder 1, a groove 5 is provided on the semicircular tube and is sealed by a sealing plate, thereby reducing the water flow.
[0026] During assembly, the upper header 2, the jacket tube 4, and the lower header 3 can be connected to the cylinder 1 by welding. The slot 5 can vertically penetrate the jacket tube 4, with its upper and lower ends connected to the upper header 2 and the lower header 3, respectively. Alternatively, the slot 5 can be positioned within the jacket tube without penetrating the jacket tube 4. In this configuration, to mitigate the impact of cooling water on the slot 5, the upper and lower ends of the slot 5 are configured as arc surfaces 52. The sealing plate includes a first sealing plate 51 that blocks the left and right openings of the jacket tube slot and a second sealing plate 53 that blocks the upper and lower openings of the jacket tube slot. The second sealing plate 53 is used to seal the arc surfaces 52. Because the slot 5 is longitudinally disposed and has a relatively long vertical length, a reinforcement plate (not shown) is provided between the two second sealing plates 53 used to seal the slot 5 to enhance the strength of the device. The reinforcement plate can be provided at multiple locations from top to bottom to connect the two second sealing plates 53 and enhance the strength of the device.
[0027] The device ensures that the cylinder 1 can be properly cooled by providing the slots 5 , thereby reducing water consumption and also lowering the coal content in the slag.
[0028] Example 2
[0029] like Figure 5 and Figure 6 As shown, in this embodiment, the jacket tube 4 is a cylinder surrounding the outside of the cylinder body 1, and the slots 5 are opened on the cylinder.
[0030] The other structures of this embodiment are consistent with those of the first embodiment.
