Description

Technical Field

[0001] The utility model belongs to the technical field of storage equipment, and in particular relates to a storage tank material capture system based on storing materials that are easy to form aerosols. Background Art

[0002] In the process of using traditional storage tanks, since the material is easy to form aerosols or dissolve in the gas, the gas exhaled by the breathing valve contains more material, which condenses after encountering cold air at the breathing valve outlet and adheres to the breathing valve outlet, causing the material to escape and waste. At the same time, the breathing valve outlet needs to be cleaned frequently;

[0003] In view of this phenomenon, a material capture system based on a storage tank for storing materials that are prone to forming aerosols is provided to solve the problems of breathing valve outlet adhesion and material leakage. Summary of the invention

[0004] Purpose of the invention: The purpose of the utility model is to provide a material capture system for a storage tank based on storing materials that are easy to form aerosols, so as to solve the technical problems of adhesion at the outlet of the breathing valve and material leakage.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a material capture system for a storage tank based on storing materials that are easy to form aerosols, including a storage tank and a breathing valve installed on the top of the storage tank. The storage tank breathing valve mainly meets the ventilation requirements of the size of the storage tank and is installed on the top of the storage tank storing Class A, B, and C liquids in conjunction with the flame arrester. The storage tank breathing valve is an important accessory to protect the safety of the oil tank. It is installed on the top plate of the oil tank and consists of two parts: a pressure valve and a vacuum valve. Its function is to maintain the airtightness of the oil tank under normal circumstances and reduce the evaporation loss of oil products to a certain extent. When necessary, it can automatically ventilate and adjust the pressure inside and outside the oil tank to balance the pressure, which plays a safety role for the oil tank. It is characterized by:

[0006] Material catcher; the material catcher is installed between the storage tank and the breathing valve;

[0007] A concentration detector is installed at the inlet of the breathing valve to detect the concentration of the material entering the breathing valve, and a remote concentration detector is used.

[0008] Furthermore: the material catcher has a double-layer material capture screen and a screen capture temperature sensor, and a remote transmission screen capture temperature sensor is used;

[0009] Wherein, the double-layer material capturing wire mesh is installed at the entrances and exits of the material capturer which are far away from each other.

[0010] Further: the material catcher has a heating chamber, and hot steam is input into the heating chamber from the heating pipe for heating;

[0011] The heating hot water valve and the normally open valve are arranged in sequence on the heating pipeline, and the heating hot water valve and the normally open valve are remote valves.

[0012] Furthermore: a cooling water circulation pipeline is connected between the heating hot water valve and the normally open valve of the self-heating pipeline, a cooling water valve is arranged on the cooling water circulation pipeline, and a remote cooling water valve is adopted.

[0013] Compared with the prior art, the utility model has the following advantages: by adding a material catcher and a pipe for heating and cooling the material catcher, the interception rate of the gas material can be improved by cooling when the concentration increases, and the condensed material can be melted by increasing the temperature of the material catcher when the concentration decreases, and the utility model is suitable for comprehensive promotion and application.

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] In the description of the invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0018] In the embodiments of the present invention, Figure 1-Figure 2 As shown, a material capture system based on a storage tank for storing materials that are easy to form aerosols includes a storage tank 1 and a breathing valve 2 installed on the top of the storage tank 1, characterized in that:

[0019] Material catcher 3; the material catcher 3 is installed between the storage tank 1 and the breathing valve 2;

[0020] A concentration detector 4 is installed at the inlet end of the breathing valve 2 to detect the concentration of the material entering the breathing valve 2;

[0021] The material catcher 3 has a double-layer material capture screen 37 and a screen capture temperature sensor 38;

[0022] The double-layer material capturing mesh 37 is installed at the inlet and outlet of the material capture device 3 which are far away from each other. The double-layer material capturing mesh 37 intercepts the material in part of the gas, thereby reducing the concentration of the material in the gas entering the breathing valve 2.

[0023] In another embodiment of the present invention, Figure 1-Figure 2 As shown, the material catcher 3 has a heating chamber 31, and hot steam is input into the heating chamber 31 from a heating pipe 32 for heating;

[0024] The heating pipe 32 is provided with a heating hot water valve 33 and a normally open valve 34 in sequence;

[0025] A cooling water circulation pipe 35 is connected between the heating hot water valve 33 and the normally open valve 34 of the heating pipe 32, and a cooling water valve 36 is arranged on the cooling water circulation pipe 35;

[0026] Since installing a material catcher alone cannot solve the problem of pre-condensation of gas containing material at the outlet of the breathing valve;

[0027] By adopting the above technical solution: the normally open valve 34 is kept in a normally open state. When the storage tank 1 stores liquid polycarboxylate water-reducing agent, the gas entering the material catcher 3 intercepts the material in part of the gas through the double-layer material capture mesh 37, thereby reducing the material concentration in the gas entering the breathing valve 2 and then entering the breathing valve 2 through the pipeline. Before entering the breathing valve 2, the concentration detector 4 detects the material concentration in the gas. If the detected concentration exceeds the set threshold, the opening of the hot water valve 33 is controlled to be smaller, and the opening of the cooling water valve 36 is controlled to be larger, so that the temperature of the material catcher is reduced, thereby improving the capture capacity and reducing the material escaping from the outlet of the breathing valve 2.

[0028] When the concentration at the inlet of the breathing valve 2 drops to the set threshold, the opening of the heating hot water valve 33 is controlled to become larger, and the opening of the cooling water valve 36 is controlled to become smaller, so that the inner height of the material catcher 3 gradually rises, and the drop-shaped material condensed on the double-layer material capture mesh 37 melts and flows back into the storage tank 1.

[0029] In another embodiment of the present invention, Figure 2 The material catcher is cut flat, and a flange connection is adopted at the connection between the upper half and the lower half. After the double-layer material screen 37 is used for a long time and frequently switches between hot and cold, the double-layer material capture screen is replaced by opening the flange.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
