Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically a raw coal gas compressor. Background Technology

[0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas; it is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe, providing power for the refrigeration cycle. Coke oven gas, also known as raw coal gas, is the original gas produced during the coking and gasification of coal. It is rich in effective components such as hydrogen and carbon monoxide, but also contains large amounts of impurities such as tar, naphthalene, hydrogen sulfide, ammonia, and dust.

[0003] Small particulate solid impurities in raw coal gas can affect the normal operation of the compressor if they enter it over a long period of time. Secondly, the tar and other oily impurities in raw coal gas can easily coke inside the compressor, which will also affect the operation of the compressor. Utility Model Content

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] Figures 1-5 The diagram shown is a structural schematic of one embodiment of a raw coal gas compressor according to this utility model. Please refer to [link / reference]. Figures 1-5 This utility model discloses a raw coal gas compressor, the main body of which includes:

[0034] Cyclone separator 1, mist collector 2 connected to cyclone separator 1 via flange, atomizing nozzle 3 connected to mist collector 2, atomizing nozzle 3 installed on the pipe of collection discharge pipe 24, compressor 4 connected to mist collector 2 via flange, and gas-liquid separator 5 connected to compressor 4 via flange.

[0035] The cyclone separator 1 includes a support frame 11 symmetrically welded and fixed to the outer wall of the cyclone separator 1, a blower 12 bolted to the top of the cyclone separator 1, a raw coal gas inlet pipe 13 welded and fixed to one side of the cyclone separator 1, a raw coal gas outlet pipe 14 welded and fixed to the other side of the cyclone separator 1, and an impurity collection box 15 connected to the bottom of the cyclone separator 1. The bottom of the cyclone separator 1 has an impurity discharge pipe, which is inserted into the inner cavity of the impurity collection box 15. After the raw coal gas is introduced into the cyclone separator 1, the swirling flow generated by the blower 12 will drive the raw coal gas to rotate. The centrifugal force generated by the rotation of the raw coal gas causes solid impurities to separate and fall into the impurity collection box 15.

[0036] The compressor 4 includes a compressor inlet pipe 41 welded and fixed to one end of the compressor body, a compressor outlet pipe 42 welded and fixed to the other end of the compressor body, and fixed support legs 43 symmetrically welded and fixed to the bottom of the compressor body.

[0037] The gas-liquid separator 5 includes a separation pipe 51 connected at one end to the compressor outlet pipe 42 via a flange and welded to the gas-liquid separator 5 at the other end, a liquid discharge pipe 52 welded to the bottom end of the gas-liquid separator 5, and a gas discharge pipe 53 welded to the top end of the gas-liquid separator 5. The gas-liquid separator 5 is designed with baffles or baffles in its inner cavity to suddenly decelerate and change the direction of the high-speed incoming airflow, and to separate the liquid droplets by using inertia.

[0038] The micro-mist collector 2 is connected to the raw coal gas outlet pipe 14 via a flange. It includes an installation groove 21 at the top of the micro-mist collector 2, an arc-shaped cover 22 that is locked in the installation groove 21 and sealed by a sealing ring, and a stainless steel mesh capture plate 23 that is evenly fixed to the bottom surface of the arc-shaped cover 22 by bolts. The stainless steel mesh is a ring-shaped plate with multiple stainless steel wires welded and fixed inside. The stainless steel mesh is used to capture tar substances and a collection discharge pipe 24 connected to the other end of the micro-mist collector 2 via a flange. The collection discharge pipe 24 is connected to the compressor inlet pipe 41 via a flange. A lifting ring 25 is fixed to the top of the arc-shaped cover 22. Lifting the lifting ring 25 makes it easy to lift the arc-shaped cover 22, so that the stainless steel mesh capture plate 23 can be inserted and removed from the opening at the top of the tank of the micro-mist collector 2 like a drawer, which is convenient for replacement.

[0039] The atomizing nozzle 3 is installed on the collection and discharge pipe 24, including a nozzle connector 31 welded and fixed to the top of the collection and discharge pipe 24, a cleaning agent inlet pipe 32 inserted into the nozzle connector 31 and sealed by a sealing ring, and a spray tube 33 uniformly welded and fixed to the cleaning agent inlet pipe 32. A hose is connected to the cleaning agent inlet pipe 32, and a metering pump is installed on the hose. The metering pump is connected to the cleaning agent storage box through the hose. The metering pump can accurately pump the cleaning agent into the inner cavity of the collection and discharge pipe 24, so that the cleaning agent comes into contact with the raw coal gas and reacts with the oily impurities to reduce the oily substances.

[0040] Furthermore, in order to better clean the raw coal gas and keep the inside of compressor 4 clean, the cleaning agent in the cleaning agent storage box is washing oil, and compressor 4 is a steam compressor. The washing oil can better remove oily substances in the raw coal gas; while the working medium of the steam compressor is high-temperature steam. During the compression process of the steam compressor, the high-temperature steam medium does not come into contact with any liquid, so no liquid droplets are added to the raw coal gas at the outlet from the compression process, reducing the load on the subsequent gas-liquid separation.

[0041] Meanwhile, in order to support the mist collector 2, specifically, a mounting bracket 26 is placed below the mist collector 2 and fixed to the ground by bolts. An arc-shaped support plate 27 is fixed to the top of the mounting bracket 26. The mist collector 2 is placed on the arc-shaped support plate 27. The arc-shaped support plate 27 can fit the mist collector 2 inside, which can better place the mist collector 2.

[0042] Finally, in order to reduce the liquid in the gas discharged from the gas discharge pipe 53, a wire mesh demister is fixed to the inner wall of the gas discharge pipe 53 by bolts to capture the last remaining fine liquid mist in the raw coal gas.

[0043] Combination Figures 1-5 The specific implementation method of this raw coal gas compressor is as follows:

[0044] 1. First, after the raw coal gas is introduced into the cyclone separator 1, the swirling flow generated by the blower 12 will cause the raw coal gas to rotate as well. The centrifugal force generated by the rotation of the raw coal gas causes solid impurities to separate and fall into the impurity collection box 15, which is a preliminary impurity removal.

[0045] 2. Then the raw coal gas is introduced into the micro-mist collector 2, where the stainless steel wire mesh of the stainless steel mesh capture plate 23 captures the tar substances. Then it passes through the atomizing nozzle 3 and comes into contact with the sprayed cleaning agent. The oily substances in the raw coal gas are reacted and removed, which is a fine impurity removal process.

[0046] 3. Finally, the raw coal gas is compressed in the compressor 4 and then passed into the gas-liquid separator 5 to separate the gas and liquid.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
