Detailed Description
In this embodiment, the carbonization tower includes a plurality of water tank 7, and it is used for wearing to establish the titanium pipe hole of titanium pipe 8 to open on the corresponding both sides wall of water tank 7, wears to establish a plurality of titanium pipes 8 in a water tank 7, and the downthehole side of titanium pipe is opened has seal groove 9, installs O type sealing washer 10 and thrust pad 11 in the seal groove 9.
The technical solution claimed in the present invention is further clearly and completely illustrated by a specific embodiment.
In the embodiment, the carbonization tower consists of 1 base, 8 water-saving tanks 7, 21 tower rings and 1 top cover, and each carbonization tower is divided into 31 sections. The titanium pipes 8 in the water tanks 7 need to be penetrated in a construction site, and the number of the titanium pipes is 312/the water-saving tanks 7, one titanium pipe 8 is matched with 4O- shaped sealing rings 10 and 2 thrust rings for sealing, the total number of 21 carbonization tower devices is 168 water tanks 7, and the number of the titanium pipes is 52416. Because the construction workload is large, the sealing property, the progress and the hoisting process of the water tank 7 after pipe penetration are the key points of construction.
Firstly, a baffle and a knocking cylinder for assisting in penetrating the titanium pipe 8 are processed, and the structures of the baffle and the knocking cylinder refer to fig. 1 and fig. 2 respectively.
The baffle includes angle steel connecting piece 1, steel sheet 2 and steel pipe spliced pole 3, and two steel pipe spliced poles 3 vertical fixation are in angle steel connecting piece 1 side surface, and every steel pipe spliced pole 3 respectively is connected with a steel sheet 2. The two ends of the angle steel connecting piece 1 of the baffle are provided with bolt holes corresponding to the connecting holes on the water tank 7. Stud and baffle use together, can dismantle the connection with baffle and 7 sides of water tank.
The knocking barrel comprises a barrel 4 and a knocking barrel pipe 5 fixed at the rear end of the barrel 4, and the barrel 4 can enter a sealing groove 9. The end of the knocking bobbin 5 is connected with a bearing plate 6. When in use, the bearing plate 6 is beaten by an axe or a hammer.
Then, the O-shaped sealing ring 10 and the thrust pad 11 are put into a bucket filled with soapy water for lubrication and soaking; several bottles of soapy water are prepared for lubricating the contact surfaces of the O-shaped sealing ring 10, the titanium pipe 8 and the titanium pipe hole during installation.
The titanium pipes 8 are pre-arranged in the corresponding titanium pipe holes at two sides of the water tank 7 in a penetrating way, and the baffle is fixed at one side of the water tank 7, so that the titanium pipes 8 are prevented from being uneven in length when being knocked and fastened. Sequentially installing two O-shaped sealing rings 10 on the other side of the water tank 7, respectively penetrating the O-shaped sealing rings 10 on the titanium tube 8 during installation, then sleeving the cylinder 4 of the knocking cylinder on the titanium tube 8, and knocking the tail end of the knocking cylinder tube 5 to seal; then, sleeving the thrust pad 11 to finish fastening the titanium pipe 8 of the side water tank 7; then the baffle plate is removed, the baffle plate is installed on one side of the water tank 7 with the fastened titanium pipe 8 again, and the O-shaped sealing ring 10 and the thrust pad 11 are continuously installed on the other side of the water tank 7 with the unfastened titanium pipe 8.
If the O-ring 10 is found to be loose, a sharp thin iron needle is used to blow air between the two O-rings 10, and the O-rings are tapped again to confirm that the seal is complete and then the thrust pads 11 are inserted.
The above is repeated, and the titanium pipes 8 on all the water tanks 7 are installed.
Treatment of foundations
When the 350t crawler crane is used for hoisting equipment, the bearing capacity per square meter is 48.8KN, 1m thick sand inclusion stones need to be backfilled to the foundation on site to meet hoisting conditions, and a roadbed box needs to be laid below the 350t crawler crane.
And after the titanium pipe 8 is installed, hoisting the carbonization tower equipment in sections.
As the carbonization plant is of a civil structure, the equipment hoisting design determines the number of segments to be hoisted and the performance of the selected crane according to the elevation of each layer of the carbonization plant. Because the field is smaller, 350t crawler crane tower type working condition is selected for actual hoisting, and conflict with civil engineering construction is reduced.
The whole hoisting process is described by taking one section (hereinafter, referred to as hoisting section) of the carbonization tower as an example.
Hoisting in a trial manner: after the hoisting section is assembled at the designated position, the welding inspection of the lifting lug is completed; after the field is processed and the field is qualified through inspection, the 350t crawler crane stands according to the designated position; after the hoisting machine rigging is suspended, the hoisting machine hoists, the hoisting section is hoisted to 200mm away from the prefabricated platform, and after the equipment, the hoisting machine, the hoisting rigging and the lifting lug are checked to be free of abnormal conditions, hoisting is continued.
Formal hoisting: and continuously lifting the 350t crawler crane, continuously lifting the hook when the bottom of the lifting section is higher than surrounding obstacles until the bottom of the lifting section is higher than the in-position elevation by 300mm, stopping rotating the rod by 90 degrees clockwise for the 350t crawler crane until the lifting section is positioned right above the in-position, and finely adjusting the arm rod and the back hook to enable the lifting section to be stably in position.
