Однако для известной компрессорной установки необходимо иметь посторонний источник жидкости для испарительного охлаждения с системой очистки и насосами, так как эта жидкость должна быть очищена от посторонних примесей и, кроме того, в ней происходят потери конденсата паров жидкости, выделяющегося из компримируемого газа в газоохладителе, так как этот конденсат обычно не используется.However, for a known compressor installation, it is necessary to have an external source of liquid for evaporative cooling with a cleaning system and pumps, since this liquid must be cleaned of impurities and, in addition, condensate losses of liquid vapor generated from the compressed gas in the gas cooler occur in it, so as this condensate is not commonly used.

Целью данного изобретения является повышение экономичности установки путем использования конденсата для испарительного охлаждения.The aim of this invention is to increase the efficiency of the installation by using condensate for evaporative cooling.

Указанная цель достигается тем, что конденсатосборники подключены к проточным частям секций сжатия.This goal is achieved by the fact that the condensate collectors are connected to the flowing parts of the compression sections.

На чертеже представлена схема компрессорной установки.The drawing shows a diagram of a compressor installation.

Установка содержит последовательно расположенные секции 1—3 сжатия и холодильники — промежуточные 4, установленные между секциями, и концевой 5. Каждый холодильник снабжен конденсатосборником 6, который подключен к проточной части секции, при помощи трубопроводом 7. На трубопроводах, идущих от конденсатосборников, установлены обратные клапаны 8 и запорные'органы 9. К трубопроводам 7 подсоединена также линия 10 для подачи конденсата со стороны. Конденсатосборники 6 имеют также сливную линию’ 11 для слива излишков конденсата.The installation contains sequentially arranged compression sections 1-3 and refrigerators - intermediate 4, installed between the sections, and end 5. Each refrigerator is equipped with a condensate collector 6, which is connected to the flow part of the section using a pipeline 7. The return pipes are installed on pipelines coming from the condensate collectors valves 8 and shut-off bodies 9. A line 10 for supplying condensate from the side is also connected to the pipelines 7. Condensate collectors 6 also have a drain line ’11 for draining excess condensate.

Установка работает следующим образом.·Installation works as follows. ·

При сжатии газа, содержащего пары жидкости, например, атмосферного воздуха или азота из мокрого газгольдера, в секциях сжатия 1—3 и его охлаждении в промежуточных холодильниках 4 и концевом холодильнике 5 выделяется конденсат, который стекает в конденсатосборники 6. Кон3 денсат из конденсатосборников по трубопроводам 7 подается в проточную часть секций сжатия, ’так как давление в холодильниках и .сборниках конденсата выше, чем на входе в секцию сжатия. В проточной'части жидкость испаряется, охлаждая газ в про- $ цессе сжатия, за счет чего достигается положительный эффект — увеличение производительности компрессора, снижение удельной работы сжатия.When a gas containing vapor of liquid, for example, atmospheric air or nitrogen, is compressed from a wet gas tank, condensation is generated in the compression sections 1-3 and cooled in the intermediate refrigerators 4 and the terminal cooler 5, which flows into the condensate collectors 6. Con3 condensate from the condensate collectors through pipelines 7 is supplied to the flow part of the compression sections, since the pressure in the refrigerators and condensate collectors is higher than at the inlet to the compression section. In the flow part, the liquid evaporates, cooling the gas in the process of compression, due to which a positive effect is achieved — an increase in compressor productivity and a decrease in the specific work of compression.

В случае, когда влагосодержание газа на входе в компрессор недостаточно для об- ¹⁰раЗования конденсата в холодильниках, подается конденсат со стороны по линии 10. Обратные клапаны 8 предохраняют в этом случае холодильники от залива их конденсатом. Количество конденсата, подаваемо- ₁₅го в проточную часть каждой из секций сжатия регулируется запорным органом 9.In the case when the moisture content of the inlet gas to the compressor is insufficient For creation of the condensate ¹⁰ mations in refrigerators, is fed from the condensate via line 10. The check valves 8 to prevent this case from the Gulf of refrigerators condensate. The amount of condensate supplied to the flow part of each of the compression sections _{on the} 15th is regulated by the shut-off element 9.

Излишки конденсата сливаются по линии 11.Excess condensate is discharged along line 11.

Подключение конденсатосборников к проточным частям секций сжатия позволяет устранить посторонний'источник жидкости для испарительного охлаждения с системой ее очистки и насосами, так как используется перепад давлений в компрессорной секции.The connection of the condensate collectors to the flowing parts of the compression sections allows eliminating the extraneous source of liquid for evaporative cooling with its cleaning system and pumps, since the differential pressure in the compressor section is used.

Claims

(54) COMPRESSOR INSTALLATION The invention relates to the field of compressor engineering and concerns the design of compressor units for gas compression with cooling. The closest technical solution to the invention with respect to the technical essence and the achieved result is a compressor installation comprising successive compression sections with coolers installed behind them having condensate traps 1. However, for a known compressor installation, it is necessary to have an external source of liquid for evaporative cooling with a cleaning system and pumps, since this liquid must be free from impurities and, in addition, there will be a loss of condensate of liquid vapors released from the compressed gas. gas cooler since this condensate is not normally used. The purpose of this invention is to increase the efficiency of the plant by using condensate for evaporative cooling. This goal is achieved by the fact that the condensate traps are connected to flow sections of the compression sections. The drawing shows a diagram of the compressor unit. The installation contains sequential compression sections and refrigerators — intermediate 4, installed between the sections, and end 5. Each refrigerator is equipped with a condensate collector 6, which is connected to the flow section of the section, by means of pipe 7. Non return valves 8 are installed on the pipelines coming from the condensate collectors. and shut-off devices 9. A line 10 is also connected to pipelines 7 for supplying condensate from the side. The condensate trap 6 also has a drain line 11 for draining excess condensate. The installation works as follows. When compressing a gas containing liquid vapors, for example, atmospheric air or nitrogen from a wet gas tank, condensation sections 1-3 and its cooling in intermediate coolers 4 and terminal cooler 5 release condensate that flows into condensate collectors 6. Condensate from condensate collectors The pipes 7 are supplied to the protochip part of the compression sections, since the pressure in the refrigerators and condensate collectors is higher than at the entrance to the compression section. In the flow part, the liquid evaporates, cooling the gas during the compression process, thereby achieving a positive effect — an increase in the compressor capacity, a decrease in the specific compression work. In the case when the moisture content of the gas at the inlet to the compressor is not sufficient for the formation of condensate in refrigerators, condensate is supplied from the side through line 10. The check valves 8 in this case prevent the condensers from being filled with condensate. The amount of condensate supplied to the flow part of each of the compression sections is regulated by the shut-off device 9. Excess condensate is drained through line 11. Connecting the condensate traps to the flow parts of the compression sections eliminates the extraneous source of evaporative cooling fluid with its cleaning system and pumps, since the differential is used pressure in the compressor section. Claims Compressor installation, containing, and successively arranged compression sections with coolers installed behind them, having condensate traps, characterized in that, in order to increase efficiency by using condensate for evaporative cooling, the condensate traps are connected to flow sections of the compression sections.
