Description

Technical Field

[0001] The invention relates to the technical field of rainproof sheds, in particular to a rainproof shed for storing desulfurization gypsum in a power plant. Background Art

[0002] Power plant desulfurization gypsum is a byproduct of wet desulfurization in coal-fired power plants. Its main component is calcium sulfate dihydrate (CaSO4·2H2O), with a moisture content of approximately 10%-15%. Due to its strong hygroscopicity, it is prone to moisture absorption and agglomeration (hardening at a moisture content of >20%) when stored in the open air, and it is mixed with impurities, which reduces its value as a building material. In addition, rainwater erosion may cause dust pollution or calcium sulfate seepage into groundwater. Rain shelters can extend the storage period of gypsum by isolating moisture and controlling temperature and humidity, thereby ensuring its activity and purity. At the same time, they meet environmental regulations on dust and wastewater emissions, reducing resource waste and processing costs. Rain shelters are one of the facilities for storing gypsum.

[0003] In the existing technology, traditional fixed roofs (such as color-coated steel plates) are completely enclosed. Although they can prevent rain, they cannot drain moisture from the gypsum pile, causing caking. Simple tarpaulin covering solutions have poor air permeability of the fabric, which easily forms internal condensation water during the rainy season. The flat roof structure is prone to water accumulation, and the edge drainage trough capacity is insufficient. During heavy rain, overflow and infiltration of the gypsum pile occur. Therefore, there is an urgent need for a rainproof shed for storing desulfurization gypsum in power plants to solve the above problems. Summary of the Invention

[0008] As a further solution of the present invention, a third fixing plate is fixedly installed on one side of the portal steel frame at the front end and the rear end, and the third fixing plate is fixedly installed with the first fixing plate. Side panels are fixedly installed on both sides of the portal steel frame, and the side panels are fixedly installed with the bottom surface of the first fixing plate, and the third fixing plate is fixedly installed with the side panels.

[0026] It should be noted that during storage, the water in the gypsum will gradually evaporate into water vapor. Then, by setting the PTFE microporous membrane 7 into a three-layer composite structure (outer layer pore size 2-5μm, middle layer 5-10μm, inner layer 10-20μm), it can block rainwater and improve air permeability (experimental data show that the moisture permeability can be maintained at ≥4000g / (m 2 ·24h), the emitted water vapor will pass through the vent 4, the support mesh 5 and the PTFE microporous membrane 7, and be discharged through the gap between the corrugated plate 6 and the support bar 8. The PTFE microporous membrane 7 is supported by the support mesh 5 to prevent the membrane from sagging and being damaged by wind vibration.

[0027] like Figure 2 、 Figure 3 and Figure 6 As shown, the drainage assembly includes: a water collection trough 13, which is arranged on both sides of the portal steel frame 1, and the inner circular walls of several drainage outlets at the bottom of the water collection trough 13 are connected to siphon drainage pipes 14, and a seepage blind ditch 15 is provided at the bottom of the siphon drainage pipe 14.

[0028] It should be noted that when it rains, the corrugated plate 6 is made of high-density polyethylene (HDPE) corrugated plate with a nano-hydrophobic coating on the surface. The collection trough 13, siphon drainage pipe 14 and seepage blind ditch 15 are used to collect, transport and discharge rainwater. The collection trough 13 is connected to the DN200 siphon drainage pipe 14. The drainage efficiency is significantly improved during heavy rain. A seepage blind ditch 15 (gravel layer + geotextile) is set around the foundation to prevent the backflow of ground water. The rainwater is discharged into the municipal sewage pipe through the seepage blind ditch 15 to avoid rainwater splashing on the ground and splashing water mist that is sucked into the warehouse, causing local humidity to be out of control and contaminating gypsum, while preventing ground water from backflowing.

[0029] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the inner bottom surface of the portal steel frame 1 is paved with crushed stone 19, the top surface of the crushed stone 19 is cast with steel fiber concrete 18, the top surface of the steel fiber concrete 18 is paved with TPO membrane 17, and the top surface of the TPO membrane 17 is cast with epoxy mortar 16.

A PLC controller is fixedly installed on one side of the third fixed plate 11 located on the front side, and a plurality of humidity sensors 21 are provided on the bottom surface of the corrugated plate 6. The humidity sensor 21 is fixedly installed on the portal steel frame 1, and the humidity sensor 21 is electrically connected to the PLC controller. A fixing frame 22 is fixedly installed on one side of the first fixed plate 3, and the fixing frame 22 is fixedly installed on the outermost support bar 8, and the fixing frame 22 is fixedly installed on the water collection tank 13. An electric sliding door 24 is fixedly installed on one side of the third fixed plate 11 located on the front side, and the driving motor of the electric sliding door 24 is electrically connected to the PLC controller. The PTFE microporous membrane 7 is a three-layer composite structure (the pore size of the outer layer is 2-5μm, the middle layer is 5-10μm, and the inner layer is 10-20μm).

[0032] It should be noted that, at the same time, the humidity inside the portal steel frame 1 is detected by a number of humidity sensors 21 (the threshold value is set to RH = 75%). When the humidity exceeds the standard, the electric shutters 23 are automatically opened to allow air to enter the interior of the rainproof awning to form front-to-back convection ventilation.

[0033] It should be noted that when the present invention is in use, through the door-type steel frame 1, when the user needs to store gypsum, by starting the driving motor of the electric sliding door 24 to open it, the gypsum is poured into the interior of the rainproof shed, and the moisture in the gypsum will gradually evaporate into water vapor. Then, by setting the PTFE microporous membrane 7 as a three-layer composite structure (outer layer pore size 2-5μm, middle layer 5-10μm, inner layer 10-20μm), it can block rainwater and improve air permeability (experimental data show that the moisture permeability can be maintained at ≥4000g / (m 2·24h), the emitted water vapor will pass through the vents 4, the support net 5 and the PTFE microporous membrane 7, and be discharged through the gap between the corrugated plate 6 and the support bar 8. The PTFE microporous membrane 7 is supported by the support net 5 to prevent the membrane from sagging and being damaged by wind vibration. At the same time, the humidity inside the portal steel frame 1 is detected by a number of humidity sensors 21 (the threshold value is set to RH = 75%). When the humidity exceeds the standard, the electric shutters 23 are automatically opened to allow air to enter the interior of the rain shelter to form front-to-back convection ventilation. , through the epoxy mortar 16, TPO membrane 17, steel fiber concrete 18 and crushed stone 19, the epoxy mortar 16 realizes anti-slip, wear-resistant, easy to clean and impact-resistant functions, the TPO membrane 17 realizes fully enclosed waterproof and anti-seepage, the steel fiber concrete 18 realizes load-bearing, leveling and load distribution, and the crushed stone 19 realizes drainage, moisture-proof and foundation stability, effectively improving the waterproof and transportation conditions of gypsum. When it rains, the corrugated plate 6 adopts high-density polyethylene (HDPE) corrugated plate (tilted 30°) with a nano-hydrophobic coating on the surface. The water collection trough 13, siphon drainage pipe 14 and seepage blind ditch 15 are installed to realize rainwater collection, transportation and discharge. The water collection trough 13 is connected to the DN200 siphon drainage pipe 14. The drainage efficiency is significantly improved during heavy rain. The seepage blind ditch 15 (gravel layer + geotextile) is set around the foundation to prevent the reverse seepage of ground water. The rainwater is discharged into the municipal sewage pipe through the seepage blind ditch 15, avoiding the splashing of water mist by rainwater on the ground and being sucked into the warehouse to cause local humidity out of control and pollute the gypsum. At the same time, it prevents the backflow of ground water, thereby achieving the comprehensive control of gypsum.
