Control valve for a gas direct injection fuel system

A control valve for a gas direct injection fuel delivery system is provided. The control valve comprises a valve body, a poppet movably received within the valve body, and an actuator disposed within the valve body. The valve body has a first fluid path, a second fluid path, and a valve seat providing fluid communication therebetween. The poppet is capable of movement between a first position and a second position. When disposed in the first position, the poppet seals the valve seat to block fluid communication between the first fluid path and the second fluid path. The poppet permits fluid communication between the first fluid path and the second fluid path as the poppet moves from the first position to the second position. The poppet is configured so that a pressure in the first fluid path produces a force that tends to move the poppet toward the second position and a pressure in the second fluid path produces a force that tends to move the poppet toward the first position. The actuator is configured to transition between an activated and a de-activated state. The actuator prevents the poppet from being disposed in the first position when in the de-activated state and the pressure in the second fluid path does not exceed the pressure in the first fluid path by at least a first pressure differential. The actuator permits the poppet to be disposed in the first position when in the activated state.

Method for extracting lithium and nickel cobalt from waste lithium ion battery step by step

The invention discloses a method for extracting lithium and nickel cobalt from a waste lithium ion battery step by step, and belongs to the technical field of comprehensive recovery of lithium ion battery materials. The method comprises the following steps of splitting, crushing and screening a waste lithium ion battery to obtain a positive electrode material powder, carrying out reduction roasting on the positive electrode material powder with a carbon-containing reducing agent, size mixing the obtained calcine with water, adding a proper amount of calcium chloride or lime milk solution for reaction transformation, selecting lithium carbonate in the calcine to be extracted into the solution, thereby realizing separation with nickel, cobalt, manganese, iron, aluminum and phosphorus. The method can realize the preferential selective extraction of lithium, the obtained lithium solution is high in purity and lithium concentration, the extraction and impurity removal, evaporation and concentration processes are not needed, the recovery of lithium and the product preparation process are simple, the recovery rate is high, the energy consumption is low, and the environmental problem of high-concentration sodium salt wastewater is not present```.

Articulable structure in the form of a fractal

The present invention relates to an articulable structure in fractal form, comprising at least one external compartment (CE) and at least a first internal compartment (Cu) that are linked together in an articulated manner via at least one of the edges thereof, the at least two compartments (CE and Cu) essentially having the same format in the erected and flat states and the first internal compartment has smaller dimensions than the external compartment, the first internal compartment, in the erected state, being accommodated inside the external compartment, and each compartment has a polygonal format, comprising at least four lateral faces (FL) and a bottom face (FF); each compartment of the articulable structure comprises at least five quadrangular faces corresponding to the four lateral faces (FL) and to the bottom face (FF), each edge of the bottom face (FF) being linked in an articulated manner to a lower edge of the same size of one of the lateral faces (FL), and at least four identical triangular faces (T) in the form of a right-angled isosceles triangle, each triangular face (T) connecting adjacent lateral faces, with each edge corresponding to a vertical height of the triangle, being linked in an articulated manner to a lateral edge of one of the adjacent lateral faces (FL) and the edge corresponding to the hypotenuse linking the vertices of the two adjacent lateral faces, wherein the length of the hypotenuse edge of the triangular faces (T) of the first internal compartment (Cu) is equal to or less than the length of the upper edge of the lateral faces (FL) of the external compartment (CE). This structure allows the use of countless compartments arranged one inside another in succession and that may be articulated together in different ways, achieving one and the same final format.

Resourceful treatment method for incinerator slag and flying ash

The invention provides a resourceful treatment method for incinerator slag and flying ash. The incinerator slag and the flying ash can be treated with low cost; and meanwhile, the income can be increased, and sustainable development of environment-friendly treatment enterprises can be facilitated. According to the technical scheme, after the incinerator slag and flying ash to be treated are matched with mixed raw materials, the mixture is fed into a high-temperature smelting device, after the incinerator slag, the flying ash and the mixed raw materials are subjected to high-temperature smelting, glass slag is formed and discharged, and the glass slag is common solid waste and can be used for brick making, road building, sand blasting, rust removal and the like. On the basis of a high-temperature smelting device, chlorine and heavy metal in flue gas are promoted to be combined to enter into a gas phase in a high-temperature smelting mode and then enter into a subsequent treatment procedure along with the smelted flue gas. Smelting flue gas is cooled and solidified into a metal chloride product through a waste heat recovery process, a quenching cooling process and a dust removal process, and the metal chloride product serves as a raw material product in the metal recovery industry for resource utilization.
