Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery of coolers, in particular to a waste heat recovery device for coolers. Background Art

[0002] At present, during the operation of the gasifier, since the outlet coal temperature is as high as 500-600℃, in order to meet the normal discharge requirements, the gas temperature needs to be reduced to about 20-50℃. Therefore, in this process, a cooler is used to cool the high-temperature gas.

[0003] When traditional coolers cool down high-temperature coal gas, they often use cooling water inside the cooler to cool the high-temperature coal gas by heat exchange. The temperature of the cooling water after heat exchange is relatively high. The cooling water discharged from the traditional cooler is generally directly transported back to the circulating water pool, resulting in serious waste heat loss, thereby causing energy waste. In addition, although some coolers are connected to waste heat recovery pipes at their drain outlets to recycle higher-temperature cooling water, the filter installed on the waste heat recovery pipe is easily covered with a large amount of debris after being used for a period of time, and manual cleaning is required during cleaning, which reduces the convenience of maintaining the waste heat recovery pipe.

[0031] Embodiment 1: Please refer to Figures 1 to 6 :

[0032] The present utility model provides a waste heat recovery device for a cooler, including: a bottom plate 1; a cooler 2 is installed at the rear side of the upper end surface of the bottom plate 1; a heat pipe steam generator 3 is installed at the front side of the upper end surface of the bottom plate 1; a water inlet 201 is provided at the upper right end of the cooler 2, and a water outlet 202 is provided at the lower left end of the cooler 2; a waste heat recovery pipe fitting 4 is connected between the liquid inlet of the heat pipe steam generator 3 and the water outlet 202, and a driving mechanism 5 and a sweeping mechanism 6 are installed on the waste heat recovery pipe fitting 4; an air outlet 203 is provided at the upper right side of the top of the cooler 2, and an air inlet 204 is provided at the lower left side of the bottom of the cooler 2 for the entry of high-temperature gas.

[0033] The waste heat recovery pipe fitting 4 includes a first rigid water delivery pipe 401, a filter box body 402, a water delivery pump 404, a second rigid water delivery pipe 405 and a flow meter 406. The first rigid water delivery pipe 401 is fixedly connected to the water outlet 202, and the other end of the first rigid water delivery pipe 401 is fixedly connected to a filter box body 402. The water outlet on the front side of the filter box body 402 is fixedly connected to the water suction port of the water delivery pump 404, and the water delivery pump 404 is fixedly installed on the upper end surface of the bottom plate 1. The water discharge port on the front side of the water delivery pump 404 is fixedly connected to a second rigid water delivery pipe 405, and the other end of the second rigid water delivery pipe 405 is fixedly connected to the liquid inlet of the heat pipe steam generator 3. And a flow meter 406 is installed outside the second rigid water delivery pipe 405. The waste heat recovery pipe fitting 4 further includes a sundry collection bottom box 403, a C-shaped positioning plate 407, a filter screen plate 408, a filter net 409 and a sealing gasket 4010.

A filter screen plate 408 is fixedly installed on the front inner side of the sundry collection bottom box 403, and a filter net 409 is fixedly inlaid on the filter screen plate 408. Through the arrangement of the waste heat recovery pipe fitting 4, the cooling water with waste heat can be recycled.

[0034] Embodiment 2, on the basis of Embodiment 1, as Figure 4 and Figure 6 shown, the driving mechanism 5 includes a small motor 501, a driving disc 502, a driving rotating shaft 503 and a拨动柱504 (it seems there is a wrong name here, assuming it should be a correct component name). The small motor 501 is fixedly installed on the top of the filter box body 402, and a driving belt pulley is fixedly installed on the rotating shaft of the small motor 501. The driving rotating shaft 503 is rotatably connected to the right side wall of the filter box body 402, and the driving rotating shaft 503 penetrates through the right side wall of the filter box body 402. Driving discs 502 and driven belt pulleys are respectively fixedly installed at the left and right ends of the driving rotating shaft 503, and the driven belt pulley is传动连接 (should be a proper transmission connection word, like 'driven by a belt') to the driving belt pulley through a belt. A拨动柱504 (correct name needed) is provided at the edge of the left end face of the driving disc 502. Through the arrangement of the driving mechanism 5, it is used to drive the sweeping mechanism 6 to operate.

[0035] The sweeping mechanism 6 includes a sweeping brush 601, vertical guide rods 602, a driving block 603 and a strip-shaped sliding opening 604. Vertical guide rods 602 are slidably connected to both the left and right ends of the sweeping brush 601, and the two vertical guide rods 602 are fixedly connected to the rear end face of the C-shaped positioning plate 407. A driving block 603 is fixedly connected to the middle of the rear end face of the sweeping brush 601, and a strip-shaped sliding opening 604 is opened on the left end face of the driving block 603, and the strip-shaped sliding opening 604 is slidably connected to the拨动柱504 (correct name needed). Through the arrangement of the sweeping mechanism 6, a large amount of sundries covering the left side face of the filter net 409 can be swept away.

[0036] It should be noted that there seem to be some incorrect or incomplete component names in the original text (such as "拨动柱504"), which may need to be further clarified for a more accurate translation.The working principle of this embodiment is as follows: when in use, the high-temperature gas generated by the gas generator during operation enters the cooler 2 through the pipeline and the air inlet 204 and contacts the outer wall of the straight tube inside the cooler 2, and then the cooling water enters the straight tube inside the cooler 2 through the water inlet pipe 201, and cools the high-temperature gas through the outer wall of the straight tube. The cooling water after heat exchange enters the first water delivery hard pipe 401 through the water outlet pipe 202. At this time, the water delivery pump 404 is started, and the cooling water entering the first water delivery hard pipe 401 is filtered through the filter 409 and enters the second water delivery hard pipe 405, and then is transported to the heat pipe steam generator 3 through the second water delivery hard pipe 405. The cooling water with waste heat is quickly heated by the heat pipe steam generator 3 to generate steam, thereby recycling the cooling water with waste heat.

[0037] During the cooling water waste heat recovery process, the staff can detect the flow of cooling water in the second water supply hard pipe 405 through the flow meter 406. When the flow of cooling water in the second water supply hard pipe 405 is low, it means that the left side of the filter screen 409 is covered with a large amount of debris. At this time, the staff can start the small motor 501, and the shaft of the small motor 501 drives the active pulley, the driven pulley, the driving shaft 503 and the driving disk 502 to rotate, and then the driving disk 502 drives the toggle column 504 to rotate, and then the rotating toggle column 504 drives the driving block 603 and the sweeping brush 601 to move back and forth up and down, thereby sweeping away the large amount of debris covering the left side of the filter screen 409.
