Description

TECHNICAL FIELD

[0001] The utility model relates to sulfur forming drum granulator technical field specifically relates to a kind of for sulfur forming drum granulator's hydrophobic device. BACKGROUND

[0002] As an important industrial equipment, drum granulator is widely used in sulfur-containing natural gas purification plant and sulfur-containing tail gas treatment petrochemical enterprise, for manufacturing liquid sulfur into certain size sulfur solid particles.Drum granulator is mainly composed of drum group, feeding system, granulation chamber, discharge system and electrical system etc.In the operation process, multiple process and components need to use steam to keep warm, to ensure the smooth forming and granulation of sulfur.

[0003] However, drum granulator is usually at the end of steam pipe network, resulting in condensate reuse in use process exists greater difficulty.As condensate cannot be effectively recycled, on-site usually adopts the way of local discharge, which not only causes energy waste, but also affects the heat preservation effect of equipment, and further reduces the operating efficiency of granulator.

[0004] Taking the drum granulator of the unit of the applicant as an example, the processing capacity of the equipment is 15-18 tons / hour, and the steam heat tracing method is used for heat preservation, the steam pressure is 0.4MPa, the back pressure at the rear end is 0.1-0.15MPa, and the steam flow is about 200-300kg / h.Due to the existence of multiple bends, vertical climbing and horizontal extension in the return water pipeline, the ability of condensate to enter the pipe network by its own pressure is weak, and the return water is difficult.Specifically, there are 4 bends in the return water pipeline, the vertical height is nearly 8 meters, the horizontal distance is nearly 10 meters, and the climbing height is nearly 5 meters.According to engineering experience, 100 meters horizontally is equivalent to 0.1MPa pressure loss, and 10 meters climbing is also equivalent to 0.1MPa pressure loss.Therefore, the ability of condensate to enter the pipe network by its own pressure is severely limited, resulting in that condensate cannot be effectively recycled, and can only be discharged locally through the lower guide, causing energy waste and decline in heat tracing effect. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a kind of for sulfur forming drum granulator's hydrophobic device, which is connected with power gas pipe at the top of gas-liquid pump, and the power gas pipe is connected with external power gas source, when gas-liquid pump starts, under the action of power gas source in power gas pipe, the flow of condensate entering the inside of gas-liquid pump through input pipe can be powered, that is, condensate is recycled by pressurization, instead of the current local discharge of condensate on site, effectively solve the condensate return water difficulty of existing sulfur forming drum granulator after condensation, waste energy and further affect the technical problem of heat tracing.

[0006] The utility model discloses a technical scheme below realizes:

[0007] A kind of hydrophobic device for sulphur forming drum granulator, including gas-liquid pump, input pipeline and output pipeline, one end of the input pipeline is connected with the condensate water main of the drum granulator, the other end of the input pipeline is connected with the import of the gas-liquid pump, the top of the gas-liquid pump is connected with the power gas pipe that provides power for the flow of condensate water into the gas-liquid pump interior, the power gas pipe is connected with external power gas source, one end of the output pipeline is connected with the outlet of the gas-liquid pump, the other end of the output pipeline is connected with condensate water backwater main pipeline.

[0008] In the scheme, condensate water enters gas-liquid pump from the condensate water main of drum granulator through input pipeline, and gas-liquid pump provides power for the flow of condensate water through top-connected power gas pipe, so as to overcome pipeline resistance and height difference, and condensate water is pressurized and then delivered to condensate water backwater main pipeline through output pipeline, realize the efficient recovery of condensate water, avoid energy waste and equipment heat preservation effect decline caused by in-situ discharge, and improve the operation efficiency and energy utilization rate of drum granulator.

[0009] As the optimization scheme of hydrophobic device, first stop valve is connected on the input pipeline, and second stop valve is connected on the output pipeline.

[0010] In the scheme, first stop valve is arranged on input pipeline, and the flow of condensate water entering gas-liquid pump from the condensate water main of drum granulator can be adjusted, so as to flexibly control the water amount entering gas-liquid pump according to actual production situation and equipment operation state, prevent impact on gas-liquid pump due to excessive flow, or affect the overall working efficiency of hydrophobic device due to insufficient flow.Second stop valve is arranged on output pipeline, and the flow of condensate water output from gas-liquid pump to condensate water backwater main pipeline can be adjusted, so as to ensure that the flow of condensate water entering backwater main pipeline is stable and appropriate, and avoid adverse effects on backwater main pipeline due to abnormal flow, such as pressure fluctuation.

[0011] As the optimization scheme of hydrophobic device, third stop valve is connected between the first stop valve and the import of the gas-liquid pump, and output check valve is connected between the second stop valve and the outlet of the gas-liquid pump.

[0012] In the scheme, third stop valve is arranged between first stop valve and the import of gas-liquid pump, and more fine flow control and on-off operation of condensate water entering gas-liquid pump can be realized, and output check valve is connected between second stop valve and the outlet of gas-liquid pump, mainly to prevent condensate water from flowing backward.

[0013] As an optimization scheme of the hydrophobic device, an input pressure gauge is connected to the input pipeline, and an output pressure gauge is connected to the output pipeline.

[0014] In this scheme, the input pressure gauge is arranged on the input pipeline, so that the pressure of the condensed water entering the hydrophobic device can be monitored in real time. The operator can determine whether the pressure state of the drum granulator condensed water main pipe is normal according to the pressure value, and then infer whether there is a problem in the condensed water generation link. The output pressure gauge connected to the output pipeline can be used to monitor the condensed water pressure from the hydrophobic device to the condensed water return main pipeline in real time. This pressure value reflects the working effect of the gas-liquid pump and the running state of the output pipeline. When the output pressure does not meet the requirements, the possible faults of the gas-liquid pump and whether there is an increase in resistance in the output pipeline can be quickly found out, so that the equipment parameters can be adjusted or repaired in time.

[0015] As an optimization scheme of the hydrophobic device, the hydrophobic device further comprises a control system electrically connected with the input pressure gauge and the output pressure gauge, respectively, for collecting pressure data in real time, and controlling the opening or closing of the first stop valve, the second stop valve, the third stop valve and the output check valve according to a preset pressure value.

[0016] In this scheme, the control system can collect pressure data of the input and output pressure gauges in real time, and accurately grasp the pressure state at different positions of the hydrophobic device. According to the preset pressure value, it can intelligently judge whether the current pressure is within the normal range. If the input pressure is abnormal, such as too high or too low, the control system will quickly control the opening or closing degree of the first stop valve and the third stop valve to adjust the flow of condensed water entering the gas-liquid pump, so as to ensure the stable operation of the gas-liquid pump and avoid damage caused by abnormal pressure. When the output pressure does not meet the preset value, the control system will control the second stop valve and the output check valve to reasonably adjust the output condensed water, so as to ensure that the condensed water can flow back to the main pipeline with appropriate pressure and flow. This automatic control reduces manual intervention, improves response speed and control accuracy.

[0017] As an optimization scheme of the hydrophobic device, the control system is further electrically connected with the gas-liquid pump.

[0018] In this scheme, the control system can directly monitor and control the running state of the gas-liquid pump. When the control system determines that the working state of the gas-liquid pump is abnormal based on the data collected by the input pressure gauge and the output pressure gauge, such as pressure fluctuation exceeding the safe range, flow deviation being too large from the preset value, etc., it can send instructions to the gas-liquid pump in time to adjust the running parameters of the gas-liquid pump, such as changing the air intake of the power air pipe to adjust the working power of the gas-liquid pump, so that the gas-liquid pump can run under the best working condition, avoid equipment damage caused by abnormal working condition, and prolong the service life of the gas-liquid pump. In the case of serious failure or emergency, the control system can also quickly control the gas-liquid pump to stop working to prevent the accident from further expanding and ensure the safe operation of the entire drainage device.

[0019] As an optimization scheme of the drainage device, the power air pipe is a compressed air pipe connected with an external air compressor.

[0020] In this scheme, the air in the environment is compressed by the air compressor and then delivered to the gas-liquid pump through the compressed air pipe. It provides stable and strong power for the flow of condensate water in the gas-liquid pump, overcoming the problem that the condensate water of the sulfur forming drum granulator is difficult to enter the pipe network due to insufficient pressure. Compared with other power sources, compressed air has the advantages of clear and transparent, convenient transportation, no special harmful performance, no fire danger, no fear of overload, etc., and can adapt to the complex working environment of the sulfur forming drum granulator.

[0021] As an optimization scheme of the drainage device, the top of the gas-liquid pump is also connected with an exhaust line pipe.

[0022] In this scheme, when the gas pressure in the gas-liquid pump exceeds the normal working range, the excess gas can be discharged through the exhaust line pipe. This can not only ensure that the gas pressure inside the gas-liquid pump always maintains a reasonable level, ensuring the stable and efficient operation of the gas-liquid pump, but also prevent equipment failure caused by excessive gas pressure.

[0023] As an optimization scheme of the drainage device, to prevent pipe corrosion, the input pipe, the output pipe, the power air pipe and the exhaust line pipe are all made of corrosion-resistant metal pipe materials.

[0024] As an optimization scheme of the drainage device, the exhaust line pipe is provided with an exhaust valve.

[0025] In this scheme, by manually or automatically adjusting the opening of the exhaust valve, the amount of discharged gas can be flexibly adjusted according to the actual running state of the gas-liquid pump, and the gas pressure inside the gas-liquid pump can be accurately maintained within the best working range, ensuring that the gas-liquid pump is always in an efficient running state. Secondly, the exhaust valve plays an important auxiliary role in the start and stop stages of the equipment. When starting, opening the exhaust valve can quickly discharge the initial air in the gas-liquid pump, avoiding the accumulation of air affecting the suction and pressurization effect of the condensate water.

[0026] As an optimization scheme of the hydrophobic device, the power air pipe is provided with a pressure regulating valve for regulating the compressed air pressure entering the gas-liquid pump.

[0027] In this scheme, since the condensate flow and pressure generated by the sulfur forming drum granulator differ under different working conditions, the gas-liquid pump needs different power to realize effective delivery of the condensate. The pressure regulating valve can flexibly adjust the compressed air pressure entering the gas-liquid pump according to the actual working condition. When the condensate flow is large or the delivery resistance increases, the compressed air pressure is appropriately increased, so that the gas-liquid pump can obtain stronger power, and the condensate can be smoothly pressurized and delivered to the condensate return main pipeline; on the contrary, when the condensate flow is small, the compressed air pressure is reduced, so as to avoid overwork of the gas-liquid pump and reduce energy consumption.

[0028] As an optimization scheme of the hydrophobic device, the shell of the gas-liquid pump is provided with a heat preservation layer.

[0029] In this scheme, the heat preservation layer can effectively reduce the heat exchange between the gas-liquid pump and the external environment, and maintain the relative stability of the internal temperature of the gas-liquid pump. On the one hand, the heat in the gas-liquid pump is prevented from being dissipated too quickly, and on the other hand, the adverse effects of the external high-temperature environment on the internal components of the gas-liquid pump are avoided, so that the components are prevented from being deformed, aged or damaged due to overheating, and the service life of the gas-liquid pump is prolonged.

[0030] As an optimization scheme of the hydrophobic device, the outlet of the gas-liquid pump is provided with a filter.

[0031] In this scheme, the filter can effectively intercept impurities, avoid their entering the downstream equipment, make the fluid state at the outlet of the gas-liquid pump more stable, reduce the pressure fluctuation and flow change caused by impurity interference, and ensure the reliability and stability of the overall performance of the hydrophobic device.

[0032] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0033] 1. The utility model discloses a gas-liquid pump is connected with the power air pipe on the top, and the power air pipe is connected with the power gas source outside, so that when the gas-liquid pump starts, under the action of the power gas source in the power air pipe, the condensate water flow entering the gas-liquid pump through the input pipe can be powered, that is, the condensate water is recovered in the pressurized mode, and then the condensate water generated by the sulfur forming drum granulator can be well punched into the condensate water return pipeline network to realize recovery.

[0034] 2. The utility model can replace the current on-site condensate water discharge mode, effectively solve the condensate water return difficulty of the existing sulfur forming drum granulator after condensation, waste energy and then affect the technical problem of heat tracing. DRAWINGS
