A method of obtaining a compressed drained and cleaned gas

 

(57) Abstract:

The method can be used for drying and cleaning compressed gas compressor units. The gas is compressed in the compressor. Conduct preliminary drying and cleaning gas sadomasoquista followed by drying it in one of two alternately operating the adsorbers. Final drying is carried out in the limit filter. In the process of drying gas in one of the adsorbers carry out the regeneration of the second adsorber. Switching adsorbers from the drying mode to the regeneration mode and back is done with the use of fast-acting valves. When switching adsorbers pre disable saturated adsorber from highway gas injection, and within 4-6 to produce a pressure relief only from sadomasoquista, then report the last regeneration of the adsorber to the main discharge. Saturated adsorber is connected to the backbone regeneration and subsequent unloading. This reduces the idle time of operation of the compressor when switching adsorbers, which increases the efficiency of the method. 1 Il.

The invention relates to a compressor installations and can be used for drying and Oluchi compression gas compressor and the subsequent dehydration of the compressed gas using two alternately operating adsorbers, one of which works on drying and the other for regeneration of the adsorbent. Switching adsorbers from one mode to another is carried out by opening and closing valves installed before and after the adsorbers. In automated machines use a fast-acting shut-off valves with electric, pneumatic or hydraulic drive /U.S. patent 2957544, N. CL 183-4.1/.

The disadvantage of this method is that when switching adsorbers arise sudden surges of high pressure gas in the included in the work of the adsorber, resulting in rapid destruction of the adsorbent and filter elements.

A method of obtaining drained and cleaned of high pressure gas, including compressed gas in the compressor, the preliminary drying and cleaning gas sadomasoquista with subsequent drying in one of the two alternately operating the drying adsorbers, while switching adsorbers performed after preliminary discharge pressure of the adsorber working on drying /P. A. Tigorev "Handbook of marine compressors. Shipbuilding, 1981, pp. 291-295. prototype inventions/.

The disadvantages of this method include the fact that the discharge pressure of Adar And during all of this period the supply of compressed gas to the consumer stop, the compressor runs non-productive.

The aim of the present invention is to improve the efficiency of the method of obtaining a compressed to high pressure drained and cleaned gas by reducing the time of idling operation of the compressor when switching adsorbers.

The invention consists in the following.

In the process of the production of dried and purified high-pressure gas by compressing it in the compressor, pre-drying and purification in sadomasoquista, followed by drying in one of the two alternately operating the adsorbers, the final drying in the limit filter, while in the process of drying gas in one of the adsorbers carry out the regeneration of the second adsorber and switching adsorbers from the drying mode to the regeneration mode and back is done with the use of fast-acting valves, when switching adsorbers pre disable saturated adsorber from highway gas injection, and within 4 - 6 sec. produce a pressure relief only from sadomasoquista, then report the last regeneration of the adsorber with the line pressure, and a saturated adsorber is connected to the backbone regeneration with poslednego way.

Compressor station includes a compressor 1, a discharge line 2 with consistently defined sadomasoquista 3 and two parallel to the adsorbers 4 and 5, the end of the filter 6, the fast shut-off valves 7, 8, 9, 10, 11, electrically connected with the control unit 12, the check valves 13, 14, 15, 16, self-regulating discharge valve 17, pipelines, highways drying 18, pipelines, highways regeneration 19.

During operation of the compressor station gas when it is compressed in the compressor 1 flows through sadomasoquista 3 in one of the adsorbers 4 or 5, and then through the check valves 15 or 16 and the terminal filter 6 to the consumer.

The adsorbers 4 and 5 are alternately (one running on drying, and the other is regenerated). When the adsorber 4 is running on drying, the valves 8 and 11 are open, and valves 9 and 10 are closed. Compressed gas from the compressor 1 through sadomasoquista 3 enters the adsorber 4 to dehydration and drained the gas from the canister 4 through the check valve 15 and the terminal filter 6 is supplied to consumers. When the adsorbent in the adsorber 4 will become saturated with moisture, at a signal from the control unit 12 switches the adsorbers. First close the valves 8 and 11, disconnecting the adsorber 4 Magistral the deposits made from sadomasoquista 3. After 4-6 seconds. open valves 9 and 10, connecting the regenerated adsorber 5 with line drying, and close the valve 7. Through the valve 10, the adsorber 4 is connected to the backbone, and regeneration through self-regulating discharge valve 17 unload it. In the adsorber 5 through the valve 9 starts to come from sadomasoquista 3 low-pressure gas (as sadomasoquista 3 before it was unloaded), and further the pressure increases gradually, and the roll of compressed high-pressure gas from the end of the filter 6 in the adsorber 5 prevents the check valve 16, thereby eliminating the possibility of destruction of the adsorbent and filter elements in the adsorber 5.

The proposed method of producing compressed to high pressure drained and cleaned the gas more economical and efficient than known methods, and can improve the reliability of the compressor station.

A method of obtaining a compressed drained and cleaned gas, including compressed gas in the compressor, the preliminary drying and cleaning in sadomasoquista with subsequent drying in one of the two alternately operating adsorbers and final drying in the limit filter, while in the period of drying gas in one of the egenerali and back is done with the use of fast-acting valves, characterized in that when switching adsorbers pre disable saturated adsorber from highway gas injection, and within 4 to 6 to produce a pressure relief only from sadomasoquista, then report the last regeneration of the adsorber with the line pressure, and a saturated adsorber is connected to the backbone regeneration and subsequent unloading.
