Inventor
A Pressurizer is a component of a pressurized water reactor. The basic design of the pressurized water reactor includes a requirement that the coolant (water) in the reactor coolant system must not boil. Put another way, the coolant must remain in the liquid state at all times, especially in the reactor vessel. To achieve this, the coolant in the reactor coolant system is maintained at a pressure sufficiently high that boiling does not occur at the coolant temperatures experienced while the plant is operating or in an analyzed transient. To pressurize the coolant system to a higher pressure than the boiling point of the coolant at operating temperatures, a separate pressurizing system is required. That is the function of the pressurizer.
Heat pump based all-weather sea water desalination system
InactiveCN103043737AReduce pollutionReduce consumptionSeawater treatmentGeneral water supply conservationWater desalinationWater source
The invention relates to a heat pump based all-weather sea water desalination system. The heat pump based all-weather sea water desalination system comprises a compressor, an evaporative condenser, a finned evaporator, a shall-and-coil evaporator, an electronic expansion valve, a flash intercooler, a turbocharger and a negative-pressure fan. If the temperature is relatively high in summer, and the temperature of the sea water is lower than the local temperature, the finned evaporator is used as an air source heat pump to heat to prepare the fresh water; if the temperature is relatively low in winter, and the temperature of the sea water is higher than the local temperature, the shell-and-coil evaporator is used as the sea water source heat pump to heat and manufacture the fresh water, and the boiling point of the sea water is reduced by utilizing the negative-pressure fan; the turbocharger is used for realizing one-stage compression of a refrigerant, and the compressor is used for realizing the two-stage compression of the refrigerator, so that the air suction volume of the compressor is increased; the flash condenser is utilized to raise the degree of the supercooling of the refrigerator in the major cycle, thus the benefit is provided for increasing the quality and the flow rate of the refrigerator in the major cycle, and as a result, the heating capacity is improved. By adopting the sea water desalination system, fresh water can be supplied for 24 hours a day at all seasons.

Deep shale gas drilling and exploiting method and fracturing device adopted in same
The invention relates to a deep shale gas drilling and exploiting method and a fracturing device adopted in the method. The method and the device mainly aim to solve the problem that the shale gas drilling and exploiting depth is limited currently. The method includes the steps that a vertical well and a horizontal well are drilled, and the fracturing device is arranged; the diameter of the vertical well is enlarged close to a fracturing working face, an expansion screen pipe is fed into an enlarged section, the diameter of the expansion screen pipe is enlarged, a pressurizer is installed in the enlarged section, a water inlet of an intermediate-pressure water pump arranged on the ground is connected with a water source through a pipeline, water, output by the intermediate-pressure water pump, 2 MPa -10 MPa in pressure is injected into the underground fracturing working face and serves as a power source of the pressurizer at the same time, a high-pressure cavity of the pressurizer conveys high-pressure water with the maximum pressure of 140 MPa to the high-pressure pipeline communicated with the fracturing working face, and accordingly shale can be easily fractured. The fracturing device comprises an acidizing device, a sand mulling device, a program control device, the pressurizer, the intermediate-pressure water pump and a control valve. The deep shale gas drilling and exploiting method and the fracturing device adopted in the method have the advantages that deeper shale gas can be exploited.
