摘要： An apparatus is disclosed for feeding a continuous supply of carbonaceous material into a pressurized reactor for producing a product gas from the material and which contains toxic and flammable gases. The apparatus comprises a first rotary gas lock for receiving the material from ambient atmospheric condition. The first lock is supplied with a flow of nitrogen as a sealing gas to prevent air from entering the lock and the apparatus. The first lock transfers the material to a second rotary gas lock which in turn transfers the material to a screw conveyor for delivery to the interior of the reactor. The second lock is supplied with a flow of a clean product gas as a buffer gas. The clean product gas supplied to the second lock is at a pressure greater than the pressure in the reactor and prevents flow of gases from the reactor to the apparatus. An exhaust is maintained between the first and second locks which draws off nitrogen and clean product gas with the nitrogen and product gas constituting a noncombustible mixture of gases in the exhaust. Means are provided for preventing entrainment of particulate material between the first and second gas locks.

摘要： The valve of the present invention includes an inflatable seal element located in the housing seat and a gas-pressure-purge arrangement. The inflatable seal element is inflated by means of pressurized fluid to grow in size and close up clearances between gate and seat, thereby establishing a gas-tight seal between the two parts, at will. So this can be done, for example, after the valve has been operated to close (slide gate driven into the valve housing) and a gas-pressure-tight seal is desired. Prior to this event, the gas-pressure-purge arrangement is activated to blast-off solid particles from the gate surfaces where these make contact with the inflatable seal element. It is not mandatory that each and every solid particle be removed from the gate contact surfaces by means of the gas-pressure-purge arrangement. Only a reasonable amount of cleanliness on the gate contact surfaces is desirable. The inflatable seal element is capable of sealing gas-tight even when some solid particles become trapped and embedded on the inflatable seal surface. The purpose of the gas-pressure-purge arrangement is to keep the contact surfaces reasonably free of solid particles only to improve the life of the inflatable seal element. Furthermore, the inflatable seal element can be deflated to shrink in size, thereby providing increased clearance between gate and seat, when desired. So this is done just prior to the moment when the gate is to be operated (driven out of the housing) to open the valve. No scoring can occur on gate or seat on account of the increased clearance.
摘要翻译：本发明的阀包括位于壳体座中的可膨胀密封元件和气体压力清除装置。充气密封元件通过加压流体膨胀以增大尺寸，并且关闭门和座之间的间隙，从而在两部分之间随意建立气密密封。因此，例如，在阀已经操作以关闭（滑动门驱动到阀壳体中）之后，可以进行这种操作，并且需要气密密封。在此事件之前，气体压力吹扫装置被激活以从门表面吹出固体颗粒，这些颗粒与可膨胀的密封元件接触。通过气体压力清除装置，不必强制每个固体颗粒从栅极接触表面上除去。在栅极接触表面上仅需要合理的清洁度是理想的。即使当一些固体颗粒被捕获并嵌入在可充气密封表面上时，该充气密封元件也能够气密地密封。气体压力吹扫装置的目的是使接触表面合理地不含固体颗粒，以改善可充气密封元件的使用寿命。此外，充气密封元件可以放气以缩小尺寸，从而当需要时在门和座之间提供增加的间隙。所以这是在门被操作（从外壳驱动出来）打开阀门之前完成的。由于增加的清关，不得在门口或座位上发生得分。

摘要： A pressure equalization valve for alternatingly equalizing pressures between a first fluid source and at least two second fluid sources is disclosed. The pressure equalization valve includes a valve body, which includes a first port in fluid communication with the first fluid source and at least two second ports in fluid communication with the at least two second fluid sources, respectively, and a valve gate movable between a first equalizing position, wherein the valve gate allows fluid flow through one of the second ports and restrains fluid flow through another of the second ports to equalize substantially the fluid pressure between the first fluid source and one of the second fluid sources, and a second equalizing position, wherein the valve gate restrains fluid flow through the one of the second ports and allows fluid flow through the other of the second ports to equalize substantially the fluid pressure between the first fluid source and another of the second fluid sources. The valve further includes a chamber in the valve body between the first port and the second ports, wherein, as measured in planes that is sized to substantially reduce the velocity of fluid flowing between the first and second ports.
