Description
Technical Field
The invention relates to the technical field of liquid level detection, in particular to a heavy hammer type buoy liquid level meter with a sealing structure.
Background
The tar distillation process adopts tar as a raw material, the crude products comprise light oil, phenol oil, naphthalene oil, wash oil, anthracene oil, medium temperature pitch and the like, and the fine processing can be carried out on the basis of the crude products to produce more fine processing products. At present, the storage tanks for storing the raw materials and the products basically adopt a weight type buoy liquid level meter for liquid level measurement, and the weight type buoy liquid level meter has the advantages of simple structure and convenient manufacture, and is more suitable for the storage tanks for tar and the products thereof.
The conventional weight type buoy liquid level meter consists of a buoy, a steel wire rope guide floating barrel, a pulley, a weight pointer, a liquid level meter scale and the like, and is designed according to the mechanical balance principle; when the liquid level is at a certain height, the buoy floats on the liquid surface, the buoy and the heavy hammer pointer are connected through a steel wire rope at the moment and are in a traction state under the supporting and guiding action of the pulley, the gravity of the buoy is equal to the buoyancy and the traction force, so that balance can be kept, when the liquid level is lowered, the buoyancy is reduced, the gravity is greater than the sum of the buoyancy and the traction force, the buoy moves downwards, and the heavy hammer pointer moves upwards along with the buoyancy until the balance is achieved; on the contrary, when the liquid level rises, the buoyancy is increased, and the gravity is smaller than the sum of the buoyancy and the traction force, the buoy moves upwards, and the heavy hammer pointer moves downwards along with the buoy until the balance is achieved. The real-time height of the liquid level can be displayed through the scale of the liquid level gauge scale pointed by the weight pointer.
However, the conventional weight type float level gauge has a defect in design, the inner float and the outer weight pointer are connected through a steel wire rope, an opening of the steel wire rope penetrating out of the storage tank is not sealed, and product steam in the storage tank can be diffused to the surrounding space from the opening, so that the environment is polluted.
At present, the treatment method of tar and tail gas of tar products basically adopts an absorption method, namely, diffused gas is collected through a diffused gas main pipe and is directly connected to a jet mixer, and the diffused gas is sucked into the jet mixer and is strongly mixed with washing oil by utilizing negative pressure generated by circulating washing oil passing through a nozzle of the jet mixer at a high speed, so that most harmful substances in the diffused gas are absorbed, and the aim of cleaning is fulfilled. The gas-liquid mixed liquid from the jet mixer is subjected to gas-liquid separation in an oil washing tank, the gas is sent to an exhaust cleaning tower, and is discharged to the atmosphere after being sprayed for washing again through oil washing circulation, so that the basic emission standard can be met. For the diffused gas of the heavy hammer type buoy liquid level meter, the process effect is not good due to the fact that the opening through which the steel wire rope penetrates can destroy the establishment of negative pressure to a certain extent.
With the gradual increase of the national requirements for environmental protection, the treatment of the tail gas of the tar and the product storage tank is urgent. At the present stage, most enterprises adopt an absorption method and a burning method, namely, on the basis of the absorption method, the exhausted tail gas is sent to a tubular furnace through an exhaust fan, and the residual harmful substances are completely removed in a burning mode, so that the effect of the mode is better than that of a simple absorption method; however, for the conventional weight type buoy level gauge, the existence of the steel wire rope through hole not only makes the establishment of negative pressure difficult, but also causes serious waste of energy because the air accounts for a very large proportion and the quantity of gas to be incinerated after washing is very large, especially most of the gas to be incinerated is air when the sucked tail gas is washed.

In the weight type buoy liquid level meter of the embodiment, the buoy 2 and the weight pointer 14 are connected through the steel wire rope 4, the guide pipe arranged on the outer side of the steel wire rope 4 is in a closed form, and the tail end of the guide pipe is connected with the liquid seal tank 13. The guide pipe is composed of a fixed three-way pipe 7, a horizontal pipe 9 and a connecting three-way pipe 10, the steel wire rope 4 penetrating out of the closed storage tank 1 directly enters the closed guide pipe and then passes through the liquid seal tank 13, and therefore the passing part of the steel wire rope 4 is always kept in an isolated state with the outside.
The fixed three-way pipe 7 is a starting point for connecting the guide pipe and the closed storage tank 1, a pipe orifice at the bottom of the fixed three-way pipe 7 is connected with a three-way pipe mounting hole 5 of the closed storage tank 1 through a flange 6, an inner pipe orifice of the fixed three-way pipe 7 is connected with a transverse pipe 8, and a first pulley 16 is fixed on a blind plate 8 at an outer pipe orifice, so that the maintenance is convenient.
The pulley II 17 in the connecting three-way pipe 10 is fixedly connected with the blind plate 11 at the position of the outer pipe orifice, so that the maintenance is convenient, the inner pipe orifice of the connecting three-way pipe 10 is connected with the transverse pipe 9 through a flange, and the pipe orifice at the bottom is connected with the liquid sealing connecting pipe 12 on the liquid sealing groove 13 through a flange.

The liquid seal groove 13 is used for carrying out liquid seal treatment on the steel wire rope 4 after the steel wire rope comes out of the guide pipe, and the liquid seal connecting pipe 12 is inserted 150mm below the liquid level of the liquid seal groove 13, so that liquid vapor entering the guide pipe from the closed storage tank 1 cannot be diffused into external atmosphere, and the external atmosphere cannot be sucked into the closed storage tank 1.
The liquid seal groove 13 is provided with a liquid supplementing port, after the valve is opened, sealing liquid is introduced into the liquid seal groove 13 through a liquid inlet pipeline, the sealing liquid can be antifreeze glass water, and industrial water can be used under the condition of proper temperature. The observation hole 22 is welded on the top plate of the liquid seal tank 13, so that the liquid level height in the liquid seal tank 13 can be checked through the observation hole 22, and the valve is closed after the liquid level is set. A first pulley block 18 is arranged on a bottom plate of the liquid seal groove 13, the first pulley block 18 is composed of 2 pulleys in parallel, and the liquid seal groove 13 is installed on an operation platform on one side of the closed storage tank 1.
