Description

Technical Field

The utility model relates to a gas pressure adjusting device, can wide application in the application occasions such as transport and gas flow, pressure control of the gas mixture that mixes impurity. Such as the fields of pressure regulation of a coking chamber of a coke oven, a constant negative pressure stabilizing system of a raw gas recovery system and a gas collecting pipe of the coke oven, pressure regulation of the coking chamber, stable emission of tail gas of a chemical plant and the like in the field of coal coking.

Background

During the transportation of the gas mixture containing impurities, the gas pressure may be unstable for various reasons, and the pressure is required to be stable or at least to be kept floating within a certain range, so that the gas mixture needs to be pressure-regulated. However, impurities in the mixture can interfere with equipment or disturb gas supply, so that problems of pressure regulation delay, large pressure change amplitude and the like are caused, the existing pressure regulating device is poor in regulation precision, and frequent maintenance is required.

For example, in the process of coal coking, a gas collecting pipe is generally used to collect the raw coke oven gas generated by heating the coal inside the coking chamber, and during the whole coking period, the generated amount of the raw coke oven gas will vary with the temperature change in the wall of the coke oven, thereby affecting the pressure in the coking chamber. The pressure of the raw gas in the carbonization chamber must be controlled within a reasonable range, the raw gas discharge amount of the carbonization chamber is increased in time to a gas collecting pipe when the generation amount of the raw gas is maximum, the situation that the pressure of the raw gas in the carbonization chamber is too high, if the pressure of the raw gas in the carbonization chamber is too high, a coke oven smokes and catches fire, a large amount of harmful raw gas leaks out, the environment is polluted, energy waste is caused, and a large amount of raw gas leaks into a combustion chamber to damage a coke oven device is avoided; at the end of coking, the generation amount of raw gas in the coking chamber is small, and if the pressure is too low, air enters the coking chamber to combust the coke, increase ash content and reduce the quality of the coke.

Therefore, in the production process, a carbonization chamber pressure adjusting device is generally required to be arranged between a carbonization chamber and a gas collecting pipe, the carbonization chamber is communicated with the gas collecting pipe through an ascending pipe and a bridge pipe, the carbonization chamber pressure adjusting device is arranged between the bridge pipe and the gas collecting pipe, and the flow of raw coke oven gas entering the gas collecting pipe is controlled by the carbonization chamber pressure adjusting device, so that the pressure at the bottom of the carbonization chamber is ensured to be not lower than 5 Pa.

The pressure regulating device generally used at present is a single-hole carbonization chamber regulating and cutting device, and the flow area of the raw coke oven gas is controlled by moving water sealing structures such as a water sealing turning plate, an arc turning plate and the like so as to change the flow of the raw coke oven gas. However, the raw gas contains not only gas but also impurities such as graphite, condensed tar, tar slag, cooling circulating ammonia water and the like, so that the existing pressure regulating device has the following problems in use:

1. when the raw gas passes through the pressure regulating device, impurities such as graphite, tar and the like in the raw gas are easily attached to the inner wall and the water seal structure of the pressure regulating device, the flow of the raw gas is disturbed and the movement of the water seal structure is obstructed, so that the flow of the raw gas in the flowing process is unstable, and the flow of the raw gas is not easy to be accurately regulated; the stroke of the water seal structure attached with the graphite or the tar is limited, and the adjusting precision of the water seal structure on the crude gas pressure and the partition capacity of the water seal structure can be influenced.

2. Because the existing water seal structure changes the opening degree of the opening of the turnover plate through liquid overflow and utilizes the water seal liquid level to adjust the flow of the raw coke oven gas, the liquid level control change is large, gas and liquid flow are communicated into the same path, the gas and liquid surge is easy to generate, the liquid level fluctuation is caused by the falling impact of ammonia water and condensate, the airflow pressure and flow fluctuation are also caused, and the flow of the raw coke oven gas is difficult to adjust in time.

3. In order to ensure that the pressure adjusting device can normally work, the machine is often required to be stopped to maintain the pressure adjusting device and a water seal structure in the device, and attached graphite and tar blocks are cleaned, so that the production efficiency of the single-hole carbonization chamber is influenced.

Example one

The technical solution of the pressure regulator and the single-hole carbonization chamber pressure regulator of the present invention will be described in detail with reference to fig. 1 to 3 and the specific embodiment.

As shown in fig. 1 to 3, a pressure regulator of the present embodiment includes a closed container 1, a gas inlet 11 for inputting a gas to be regulated is opened at the top of the container 1, and a gas outlet 12 for outputting the gas to be regulated is provided at the side of the container 1. The bottom of the inner cavity of the container 1 is filled with liquid for liquid sealing, the regulated gas is insoluble in the liquid, the bottom surface of the inner wall of the container 1 is concave downwards to form a concave part 13, and the lowest part of the concave part 13 is provided with a liquid drainage pipeline 14.

In this embodiment, the liquid discharge pipeline 14 includes a liquid outlet and a liquid seal collecting pipe 141, the liquid outlet is opened at the lowest position of the recess 13 along the vertical direction, the liquid seal collecting pipe 141 is located outside the container 1 and is communicated with the liquid outlet, and the liquid seal collecting pipe 141 is installed with the automatic liquid level adjusting valve 15. The cavity of the container 1 positioned at the upper part of the liquid forms a first liquid seal space, and the first liquid seal space is used as a gas guide channel 2 for communicating a gas inlet 11 and a gas outlet 12. The gas inlet 11 of the container 1 is also provided with an adjusting component, and when the liquid level of the liquid changes, the liquid level of the liquid is matched with the adjusting component to change the volume of the gas guide channel 2.

In this embodiment, the automatic liquid level adjusting valve 15 can automatically adjust the opening of the valve according to the input signal to adjust the flowing speed of the liquid in the container 1, and the automatic liquid level adjusting valve 15 can be, but is not limited to, a pneumatic valve or an electric valve. The opening degree of the liquid level automatic regulating valve 15 is regulated, the speed of liquid flowing out from the liquid discharge pipeline 14 in the container 1 can be changed, the liquid level in the container 1 is influenced, and the flow of regulated gas can be timely and quickly regulated. Compare in the water seal adjusting device of present gas, the same route structure of liquid, the action of the switching of liquid level control valve 14 is easily carried out, can change the speed that liquid flows out from drainage pipeline 14 in the container 1 fast through the aperture of adjusting liquid level automatically regulated valve 15 to promote rapidly or reduce the liquid level in the container 1, and then change the volume size of water conservancy diversion passageway 2, in time and accurately adjust the flow size of the gas of being transferred, change with the pressure that the influence is transferred the gas. In addition, when the liquid in the container 1 flows out through the liquid discharge pipe 14, a part of impurities sinking into the liquid is flushed out, thereby reducing the maintenance requirement of the pressure regulator. Liquid level automatically regulated valve 15 is installed outside container 1, when container 1 inner wall need wash or liquid level automatically regulated valve 15 trouble, can conveniently pull down liquid level automatically regulated valve 15, wash container 1 to the impurity that will make the interior jam of container 1 is directly discharged from liquid seal collecting pipe 141, and liquid level automatically regulated valve 15 is also convenient for directly change and is maintained, thereby reduces the time of shutting down and maintaining.

Preferably, the regulating assembly comprises four (or more) partition plates 21 installed at the gas inlet 11 at the top of the container 1 in a vertical direction, the four partition plates 21 being parallel to each other, the partition plates 21 being integrally formed with the container 1 with the top ends of the partition plates 21 as fixed ends, and the bottom ends (i.e., free ends) of the partition plates 21 being inserted into the container 1 to be directed to the liquid level of the liquid in the container 1. One of the partition plates 21 is fixed on the edge of the side wall of the gas inlet 11 of the container 1 close to the gas outlet 12, the other three partition plates 21 are distributed on one side of the partition plate 21 away from the gas outlet 12, the four partition plates 21 are matched with the side wall of the container 1, four (or more) vertical gas channels 22 are formed at the gas inlet 11 of the container 1 in a partition manner, and the four gas channels 22 are vertical channel parts of the gas guide channel 2. The heights of the free ends of the four partition plates 21 are raised one by one in the direction toward the gas outlet 12, and the heights of the bottom end openings of the four gas passages 22 are also raised in sequence. The top end and both side edges of the partition 21 are fixedly connected with the inner wall of the container 1 in a welding mode or an integral casting mode.

When the regulated gas flows into the container 1 from the gas channel 22, the gas part in the regulated gas needs to bypass the partition plate 21 and flow out from the gas outlet 12 of the container 1; impurities contained in the gas to be regulated directly fall in the vertical direction and fall into the liquid at the bottom of the container 1, and when the gas to be regulated flows, the impurities are difficult to bypass the partition plate 21 and flow to the gas outlet 12 of the container 1, so that the impurities can be absorbed by the liquid in the container 1 as much as possible. After entering the container 1, the impurities fall along the vertical direction and are not easy to adhere to the partition plate 21, and the impurities falling into the liquid sink to raise the liquid level of the liquid, so that the volume of the gas guide channel 2 can be reduced, the flow of the gas to be regulated is reduced, and the pressure rise of the gas to be regulated is promoted. And because the impurity sinks into the liquid, the impurity can not be exposed to disturb the flow of the gas to be regulated, the gas to be regulated can be kept to smoothly and stably flow in the gas guide channel 2, and the flow of the gas to be regulated can be accurately regulated.

During the rising of the liquid level of the liquid in the container 1, the volume of the gas guiding channel 2 gradually decreases. The liquid level can be raised, the gas channels 22 can be closed one by one, each closed gas channel 22 forms a new liquid seal space, and the rest gas channels 22 which are kept unblocked still belong to one part of the first liquid seal space, namely, the volume of the gas diversion channel 2 is reduced, the number of vertical channels communicated in the gas diversion channel 2 is reduced, which is equivalent to simultaneously changing the size of the gas inlet 11 of the container 1, namely, the flow of the gas to be regulated at the gas inlet 11 can be directly regulated, and the pressure of the gas to be regulated is accurately controlled.

In this embodiment, since the height of the bottom end of the free end of each of the partition plates 21 arranged in sequence from the liquid surface (in the case where the liquid surface does not rise to the free end) gradually rises in the direction toward the gas outlet 12 of the container 1, the bottom end openings of the four gas passages 22 also gradually rise in the direction toward the gas outlet 12 of the container 1. The free ends of the adjacent partition plates 21 are not on the same horizontal plane, when the liquid level of the liquid in the container 1 rises, the bottom opening of the gas channel 22 between the adjacent partition plates 21 is gradually closed by the liquid in the container 1, namely, the size of the bottom opening of the gas channel 22 can be adjusted in a continuous adjustment mode, so that the bottom opening of the gas channel 22 is prevented from directly and instantly exposing from the liquid or being submerged by the liquid, and the situation can cause the gas pressure at the gas inlet 11 of the container 1 to be changed violently.

Pressure regulator in this scheme simple structure, difficult breaking down compares water seal structure and pressure regulating device inner wall commonly used at present and need frequently wash the maintenance, and 1 washing demands of container in this scheme are low, and liquid level automatic regulating valve 15 carries out the switching action and also need not use drive arrangement such as cylinder, electric putter, has saved a large amount of installation space, also easily connection control equipment. The automatic liquid level regulating valve 15 installed outside the container 1 is convenient to maintain, disassemble, assemble and replace, is convenient to upgrade and transform and is not limited by space.

It should be understood that if the gas inlet 11 is connected to a pre-device for generating the conditioned gas, the pressure in the pre-device can also be influenced by changing the flow rate of the conditioned gas. When the pressure of the regulated gas is changed, the pressure of the regulated gas can be conducted to the interior of the front-end device, so that the pressure in the interior of the device is changed. In addition, the method can also be suitable for adjusting the pressure or the flow of the gas without impurities, and the flow of the gas can be changed and the pressure of the gas is influenced only by adjusting the volume of the gas guide channel 2. However, when the gas does not contain moisture, the liquid may be directly supplied into the container 1 in order to raise the liquid level in the container 1.

Preferably, the container 1 is further provided with a limit high liquid level detector and a limit low liquid level detector, when the regulator needs to be completely isolated, the two detectors are respectively used for monitoring the limit high liquid level and the limit low liquid level of the liquid in the container 1, and the installation positions of the limit high liquid level detector 23 and the limit low liquid level detector 24 are higher than the bottom end of any partition plate 21. Wherein, the vertical distance between the bottom of the clapboard 21 with the highest bottom end and the limit low liquid level detector 24 is 30-50mm; the vertical distance between the limit high level detector 23 and the limit low level detector 24 is 50mm. If the limit high liquid level detector 23 monitors that the liquid level of the liquid in the container 1 exceeds the limit high liquid level, the liquid level automatic regulating valve 15 is opened to enable the liquid in the container 1 to flow out, so that the liquid level of the liquid in the container 1 falls back; if the limit low liquid level detector 24 detects that the liquid level of the liquid in the container 1 is lower than the limit low liquid level, the automatic liquid level regulating valve 15 is closed, the liquid in the container 1 is prevented from flowing out continuously, and the liquid level of the liquid in the container 1 is kept unchanged. By controlling the level of the liquid in the vessel 1 to be higher than the bottom end of the partition, the respective gas passages 22 can be closed.

The invention also provides a pressure regulator of the single-hole coking chamber of the coke oven, which has the same structure as the pressure regulator, but the liquid contained in the container 1 is ammonia water, the gas to be regulated is raw coke oven gas which is generated by the coking chamber 3 and cooled by spraying circulating ammonia water in the bridge pipe 5, and tar in the raw coke oven gas forms condensed tar in the cooling process, so that the raw coke oven gas contains impurities such as tar residues, coal dust, cooling circulating ammonia water, condensed tar and the like. The coking chamber 3 is communicated with the gas collecting pipe 6 through the ascending pipe 4 and the bridge pipe 5, the coke oven coking chamber pressure regulator is arranged between the bridge pipe 5 and the gas collecting pipe 6, and when in use, the pressure regulator of the coke oven coking chamber is controlled to operate according to the pressure in the communicated coking chamber 3, the pressure of the raw coke gas output by the coking chamber 3 is regulated, and the pressure in the coking chamber 3 is further influenced. In the operation process of the pressure regulator of the single-hole coking chamber of the coke oven, cooling circulating ammonia water, condensed tar, tar slag, coal dust and other impurities are gradually mixed into the ammonia water in the container 1.

For the pressure regulator of the single-hole carbonization chamber of the coke oven, the liquid-sealed collecting pipeline 141 directly discharges the discharged ammonia water to the gas collecting pipe 6. After the cooled raw coke oven gas passes through the gas channel 22 formed by the partition board 21, the raw coke oven gas and impurities (including cooling circulating ammonia water, condensed tar, tar slag, coal dust and the like) are separated at the bottom of the regulator, the raw coke oven gas flows to the gas collecting pipe 6 through the gas outlet 12 of the container 1 to be recovered, the impurities enter the bottom of the gas collecting pipe 6 through the liquid-sealed collecting pipe 141, are mixed with the raw coke oven gas flowing out of the gas outlet 12 of the container 1 again to receive subsequent purification treatment, can be adapted to the current raw coke oven gas purification treatment equipment, does not need to be added with new purification treatment equipment or be modified on the original purification treatment equipment, and the implementation cost of the scheme is reduced. Of course, in actual use, the discharged ammonia water may be supplied to one header pipe, and the discharged ammonia water may be sent to the ammonia water circulation tank through the header pipe.

Under the condition of empty furnace operation, for example, when coke pushing is needed, the pressure regulator of the single-hole carbonization chamber of the coke oven is required to be used for separating the carbonization chamber 3 from the gas collecting pipe 6, at the moment, the liquid level of the ammonia water in the container 1 is required to be controlled between the liquid level limit high liquid level detector 23 and the limit low liquid level detector 24, and the four gas channels 22 can be completely sealed by the liquid level of the ammonia water. And the limit high liquid level can reduce and avoid the cooling ammonia water in the container 1 and the condensed tar from flowing into the gas collecting pipe through the gas 12 outlet of the container 1.

The outer cylinder 25 is also internally fixed with a grid structure 26, the grid structure 26 is provided with six groups of holes penetrating along the vertical direction, so that the inner hole of the outer cylinder 25 is divided into six groups of gas channels 22, the six groups of gas channels 22 are uniformly distributed along the circumferential direction of the outer cylinder 25, the number of the gas channels 22 in each group of gas channels 22 is three, and the three gas channels 22 in the same group are sequentially arranged along the direction close to the axis of the outer cylinder 25. The bottom of the grating structure 26 extends downwards, so that the bottom of the grating structure is in a conical shape with the tip facing downwards, the lowest part (i.e. the tip of the conical shape) of the grating structure 26 is overlapped with the axis of the outer cylinder 25, the openings at the bottom ends of the three gas channels 22 in the same group are sequentially reduced along the direction close to the axis of the outer cylinder 25, and the bottom edge of the side wall of each gas channel 22 is positioned on an inclined arc surface.
