A heat exchanger for cooling reaction gas, wherein the respective ends of heat exchanger tubes, through which the reaction gas flows, are inserted in a respective tube plate and are surrounded by a jacket, at the two ends of which are provided a respective end chamber that is partially delimited by one of the tube plates and serves for the supply and withdrawal of the reaction gas; water, as cooling agent, flows through the inner chamber of the heat exchanger that is surrounded by the jacket and that is divided by a partition, extending perpendicular to the heat exchanger tubes, which extend through it, into two partial chambers disposed one after the other in the direction of flow of the reaction gas, each partial chamber being provided with its own supply connectors and outlet connectors for the cooling agent; boiling water flows through the partial chamber that is disposed on the inlet side for reaction gas and that is connected via a supply line and withdrawal lines with a water / steam drum; feed water flows through the partial chamber that is disposed on the outlet side for the reaction gas and that is connected via a withdrawal line with the water / steam drum. The partition between the two partial chambers permits the passage of the cooling agent that flows in the inner chamber of the heat exchanger.

The invention provides a closed type isobaric compressed air energy storage system and method. The system comprises a compressor set, a motor, a high-pressure gas storage chamber, a high-pressure liquid storage tank and an expansion set, a generator, a low-pressure gas storage chamber and a low-pressure liquid storage tank; an outlet of the low-pressure gas storage chamber communicates with an inlet of the high-pressure gas storage chamber through the compressor set, an outlet of the high-pressure gas storage chamber communicates with an inlet of the low-pressure gas storage chamber through the expansion set, so that a closed loop is formed; the low-pressure gas storage chamber is connected with the low-pressure liquid storage tank through a low-pressure liquid conveying pipeline, and thehigh-pressure gas storage chamber is connected with the high-pressure liquid storage tank through a high-pressure liquid conveying pipeline; and the compression net is provided with the motor; and theexpansion set is provided with the generator. According to the system and the method, the expansion ratio of the expansion set of the system is reduced, and air is fully expanded in each stage of expansion machines; and the complexity of the system is reduced, the pressure loss caused by a throttling pressure-stabilizing valve of a traditional compressed air energy storage system is eliminated, the compressor set and the expansion set of the system can be operated under a stable working condition, and the efficiency and economical efficiency of the system are improved.

A lift converging multiway valve belongs to the technical field of forklift multiway valves, and comprises an oil inlet and return valve plate and an oil inlet valve plate, wherein a lift converging valve plate, an inclined valve plate and an accessory valve plate are coordinately arranged between the oil inlet and return valve plate and the oil inlet valve plate, the oil inlet and return valve plate and the lift converging valve plate are arranged into an integral structure, a speed limit valve is arranged on the oil inlet and return valve plate, a lift valve rod is coordinately arranged in the lift converging valve plate, an oil channel and a group of oil ports are coordinately arranged in the multiway valve, an oil inlet check valve is coordinately arranged on the oil channel, and a safety valve is coordinately arranged at one side of the oil inlet and return valve plate. The double-pump working state is only applied when a forklift doorframe is lifted, for other motions of the doorframe, only one pump is required to work, the other pump unloads at low pressure, the normal lift motion of a forklift is ensured, the energy consumption loss of an engine or a motor is also decreased, the use of an oil pipe of a system is reduced, the lift converging multiway valve has a simple structure, the utilization rate of a valve body is improved, the manufacture costs of the valve and a pipeline can be saved, the pressure loss of the valve body can also be reduced, so an energy-saving effect is realized.

A dehumidifier has a water receiving tray receiving condensed water of the dehumidifier. The water receiving tray comprises a water tank outlet, a main water outlet arranged outside the casing of the dehumidifier as a whole, the main water outlet being arranged opposite the water tank outlet; a pump used for draining is provided on the bottom of the outside of the water receiving tray, the pump being directly connected with the water receiving tray, eliminating the need of providing a pipe to connect with the dehumidifier pump, therefore reducing the risk of leaking. By connecting the pump with the water receiving tray directly, the pressure loss due to the connection of pipe is eliminated; the drainage capacity of the pump is utilized fully. Without installing or detaching additional pipes during installment or maintenance, operation is easier.

An ambient air intake duct of a static gas turbine is provided, having at least one filter, which is arranged in the intake duct, for cleaning the ambient air (A) that can flow through the intake duct. A method for operating a static gas turbine which is equipped with a filter for cleaning the ambient air (A) is also provided. To rapidly provide a higher level of gas turbine power to a generator, it is provided that, by means of a bypass or by means of flaps arranged downstream of the filter, partially to completely unfiltered ambient air (A) can temporarily flow into the compressor inlet.

The invention discloses a novel double-gland high-pressure pipeline displacement compensator, which belongs to the technical field of heat distribution pipeline compensating device structures used in petroleum, chemical industry, light industry, heating power, metallurgy and other industries. The compensator comprises an inner tube, a follower flange, an outer sleeve, a reducing extension pipe, asealing filler, an outer sleeve internal bearing platform, an inner tube convex outer ring, a composite sealing ring, a reducing tube bearing platform and the like, wherein the inner tube convex outer ring is integrally arranged on the inner tube; one end of the inner tube is inserted into the outer sleeve; the inner tube convex outer ring is positioned between the outer sleeve internal bearing platform and the reducing tube bearing platform; the composite sealing ring is pressed against between the inner tube convex outer ring and the reducing tube bearing platform; and a convex end face of the outer sleeve internal bearing platform is pressed against the other end of the inner tube so as to press the sealing filler of the follower flange. By the structure, the novel double-gland high-pressure pipeline displacement compensator has the characteristics of high precision, lower friction coefficient, smaller torque, lower pressure loss, higher bending resistance and bearing capacity, unlimited medium flow direction, reliable sealing, high performance and convenience of pipeline maintenance.
