摘要： A volatile solvent conservation modular unit and method for effecting solvent conservation is provided. The cooling coil modular unit is arranged to be disposed in the freeboard zone of a cleaning or degreasing apparatus that uses a volatile solvent. The freeboard zone chiller positioned above the vapor zone and the primary condenser to recover solvent from the relatively less dense solvent/air mixture escaping above the primary condenser and is formed so as to be disposed along one side of the degreaser vessel rather than on all four sides to minimize the obstruction of access into the vapor zone. This one-sided single freeboard chiller positioned on but one side produces a vapor suppression blanket that is effective and is readily retrofitted on existing apparatus without the need for dismantling of the existing unit.

摘要： Product cleaning apparatus having a treatment chamber provided with unheated spray cleaning zone and a sump separated by a wall and a closure member which cooperates with the wall so that the spray cleaning zone may be isolated from the sump. During such isolation of the sump and the spray cleaning zone, solvent vapors are removed to thereby facilitate introduction or removal of work into the chamber while minimizing solvent losses to the atmosphere and minimizing exposure of workers to solvent vapors.
摘要翻译：具有处理室的产品清洁设备具有未加热的喷射清洁区域以及由壁分隔的贮槽和与壁配合的封闭构件，使得喷雾清洁区域可以与贮槽隔离。在这种隔离池和喷雾清洁区域期间，除去溶剂蒸汽，从而有利于将工作引入或移出到室中，同时最小化对大气的溶剂损失并最小化工作人员对溶剂蒸气的暴露。

摘要： A housing contains a sump located below a partition wall having an opening which communicates the sump with a work receiving chamber above the partition wall. An upper condenser is provided in said chamber and a lower condenser in said sump. A chilled coil is located in the chamber above the elevation of the upper condenser but below the upper lip of the housing. Between the upper lip of the housing and the chilled coil, there is provided a vapor discharge port.

摘要： Cleaning apparatus such as a degreaser tank is provided with a vapor zone divided into upper and lower portions by a wall and a closure member which cooperates with the wall so that the upper and lower portions of the vapor zone may be isolated from one another. During such isolation of the upper and lower portions of the vapor zone, vapors from the upper portion are removed to thereby facilitate introduction or removal of work pieces into the upper portion of the vapor zone while minimizing solvent losses to the atmosphere and minimizing exposure of workers to solvent vapors.
摘要翻译：除油槽等清洗装置具有通过与壁配合的壁和封闭构件分成上部和下部的蒸气区，使得蒸汽区的上部和下部彼此隔离。在隔离蒸汽区的上部和下部的过程中，去除了上部的蒸气，从而有助于将工件引入或移除到蒸气区的上部，同时最大程度地减少对大气的溶剂损失，并最大限度地减少工人的暴露到溶剂蒸气。

摘要： Solvent is vaporized from a work product as the product moves through a process which may be a heated chamber. The vaporized solvent is withdrawn from the chamber and passed through a chiller to recover a portion of the vapor. The output from the chiller is then passed through an adsorber to remove the remainder of the solvent.
摘要翻译：当产品通过可能是加热室的过程时，溶剂从工作产品中蒸发。将蒸发的溶剂从室中取出并通过冷却器以回收一部分蒸气。然后将来自冷却器的输出通过吸附器以除去剩余的溶剂。
