Self-modulating inert gas gire suppression system

The invention relates to a valve unit (26). The valve unit (26) comprises a valve body (48) presenting an inlet (58) adapted for coupling with a source of pressurized gas (24) and an outlet (60) adapted for coupling with a gas receiver (30), and a shiftable valve member (56). The shiftable valve member (56) includes a piston seal holder (136) and an inner body section (140), and the shiftable valve member is located within said body (48) between said inlet (58) and said outlet (60) and is shiftable between a closed, gas flow-blocking position and a valve open position permitting flow of gas from said source (24) to said receiver (30). Said member (56) is normally maintained in said closed position against a valve opening force exerted there against by said source of pressurized gas (24). The valve unit (26) further comprises a spring (186) located within a spring chamber (64) operable to bias said inner body section (140) toward the valve open position, a first operating surface (S1) forming a part of said piston seal holder (136) that is exposed to said pressurized gas from said source (24), a modulation chamber (182) formed between at least a part of a second operating surface (S2) and adjacent portions of said valve body (48), a passageway (168) communicating said source (24) with said modulation chamber, pressurized gas from said source (24) exerting a valve closing force on said second operating surface (S2), and an actuator (50) operable upon actuation thereof to cause said shiftable valve member (56) to shift to the valve open position, gas from said source (24) to be delivered to said receiver, and gas from said modulation chamber to be drained therefrom.

Synergistic domestic garbage and high-alkali coal pyrolysis gasification device and method adopting three-stage type process

The invention discloses a synergistic domestic garbage and high-alkali coal pyrolysis gasification device and method adopting a three-stage type process. A pyrolysis chamber, a combustion chamber and a gasification chamber are sequentially connected to form a three-stage type synergistic domestic garbage and high-alkali coal pyrolysis treatment environment; a feeding system is connected to a pyrolysis chamber inlet; an ash collection device is arranged at each of ash collection ports of the pyrolysis chamber and the gasification chamber; the gasification chamber is connected and communicated with the pyrolysis chamber through a gas storage device; a domestic garbage material is conveyed into the pyrolysis chamber through a screw feeder, is dried on a reciprocating grate and is subjected to pyrolysis precipitation and volatilization; volatilized pyrolysis gas and tar enter the combustion chamber and are completely burned in the combustion chamber under enough air; high-alkali coal enters a central area of the gasification chamber and is in contact with flue gas generated by combustion for reaction, so that clean gasification gas is obtained and enters the gas storage device. The synergistic domestic garbage and high-alkali coal pyrolysis gasification device and method disclosed by the invention can effectively solve the problem that a large amount of tar and hydrogen chloride is contained in synthetic gas generated by a traditional domestic garbage gasification furnace can be effectively solved, so that the quality of the gasification gas is greatly improved, and the further utilization of the gasification gas is facilitated.

Bacteriocidal composition containing kresoxim-methyl and prochloraz

The invention discloses a bacteriocidal composition containing kresoxim-methyl and prochloraz, and a preparation method and use thereof. The bacteriocidal composition is characterized by containing kresoxim-methyl, prochloraz and other assistants, wherein the weight ratio of kresoxim-methyl to prochloraz is 1-80:0.5-50. The bacteriocidal composition can be used for preventing and controlling diseases in cereal crops, fruit trees, melons, vegetables and the like. The composition is widely applicable, low in cost and remarkable in effect. Indoor medicament effectiveness tests prove that the composition has an obvious synergistic effect. In addition, as there is no report on the mixing of kresoxim-methyl and prochloraz across the world, the invention provides the bacteriocidal composition.

High-tower pesticide fertilizer containing clothianidin and chlorfenapyr and preparation method of high-tower pesticide fertilizer

The invention discloses a high-tower pesticide fertilizer containing clothianidin and chlorfenapyr and a preparation method thereof. Raw materials of the high-tower pesticide fertilizer comprise urea, potassium fulvate, clothianidin, chlorfenapyr, phosphate fertilizer, potash fertilizer, diatomite and cyclodextrin; wherein the cyclodextrin wraps pesticide effective components, so that the thermal stability of the pesticide during melting is improved. According to the pesticide fertilizer, clothianidin, chlorfenapyr and the chemical fertilizer which have the insecticidal effect are mixed, breeding of pests and supply of plant nutritional ingredients can be effectively inhibited, the high-tower pesticide fertilizer generated in a high-tower mode is smooth in surface and not prone to pulverization, pesticide exerts the pesticide effect along with the fertilizer, is easily absorbed by plants and is good in upward conductivity; residues in soil are small in quantity, and environmental protection and high efficiency are achieved. The pesticide fertilizer is applied to soil before sowing or during sowing and has little influence on people, livestock and the environment, so that the fertilizer reduces the use of labor force through one-time fertilization and pesticide application, and is easy to popularize and use in a large range.
