The present application relates to a kind of high-speed boat with two skids symmetrically arranged on the bottom of deep V planing boat, the extension length and the trim angle of the skid can be adjusted, and two sets of surface propeller propulsion systems are arranged at the stern, the horizontal direction and the vertical direction of the propulsion angle can be adjusted.The present application can maintain the good seaworthiness and rapidity of deep V boat type under high sea conditions.When sailing at high speed under normal sea conditions, the lift and the upward reaction force of surface propeller on the boat body will lift the boat body out of the water, and a very high speed can be achieved.For different sea conditions, manual or automatic control mode can be selected to adjust the sailing state and speed of the boat.The present application has simple structure, small resistance and high speed when skid is sliding, and has good safety, rapidity and energy efficiency ratio under the same power;PID automatic control system is used to ensure the safety, maneuverability and rapidity of the boat;The present application provides a high-speed boat type suitable for various sea conditions for military, police and other industries.

Equipment and procedure for extraction of solids from contaminated fluids whose basic purpose is to obtain the crystallised solids from the contaminated fluids, without any type of rejection in order to evaluate them and to obtain purified water in a single stage, all in a continuous adiabatic / sonic process with evaporation / crystallisation and with low energy consumption and where the procedure is characterised by being constituted basically by at least three circuits fully interconnected as a single piece of equipment where the first circuit, the principal circuit, is constituted by an inlet duct of the contaminated fluid to be treated (1) followed by a pre-filter (2) followed by a filter for fine particles (3), a heat exchanger of preheated contaminated fluid (5) in the heat exchanger (4), followed by a fluid feedback pump (6) to a nozzle formed by an injector (7) and an ejector (8), which introduce the fluid to an evaporation chamber (9), where the steam that exits is introduced into a closed-loop electromagnetic servomechanism (26), an saturated steam ejector outlet (32), driven to the heat exchanger (4), outlet (13) as purified water from the saturated steam (22).

The utility model discloses a combined heat supply system based on an air source-water source heat pump, which comprises an air source heat pump unit, a water source heat pump unit, a user terminal and a controller, the air source heat pump unit is connected with the user terminal through a first circulating pipeline, and the water source heat pump unit is connected with the user terminal through a second circulating pipeline. The water source heat pump unit is connected with the first circulation pipeline through a third circulation pipeline, the controller is connected with the air source heat pump unit and the water source heat pump unit, and the controller controls the air source heat pump unit and the water source heat pump unit to work. The device has the beneficial effect of lower operation cost. And on the other hand, if electric heating or fuel gas or other modes are adopted for local heating, the system is complex, energy consumption is high, implementation is more tedious, and the combined heating system is simple in structure, convenient to operate and easier to implement.

The catalyst provided by the invention has the advantages of high activity, high methane selectivity and good stability when being applied to crude hydrogen purification ultralow-temperature methanation reaction.

The application discloses a front cross beam assembly, a front engine compartment assembly and a vehicle, and relates to the technical field of vehicle body structures. The front cross beam assembly is applied to a vehicle. The vehicle body of the vehicle comprises a front longitudinal beam. The front cross beam assembly comprises a front cross beam, a firewall assembly and a connecting piece. The front cross beam is provided with a first connecting position and a second connecting position which are staggered in the Y direction. The first connecting position is configured to be opposite to the rear end of the front longitudinal beam in the X direction. The firewall assembly comprises a main body and a first reinforcing piece arranged on the main body. The first reinforcing piece is connected to the second connecting position. The connecting piece is arranged at an acute angle relative to the X direction. One end of the connecting piece is connected to at least one of the front cross beam and the first reinforcing piece. The other end of the connecting piece is used to connect the front longitudinal beam. The technical scheme provided by the application aims to guarantee the resistance of the front cross beam and the firewall to the front engine compartment structure.
