Description
Technical Field
The utility model relates to a benzene hydrogenation technical field, specifically speaking, the utility model relates to a benzene hydrogenation reaction section feeding filter equipment.
Background
In the benzene hydrogenation device, crude benzene is subjected to light-heavy separation by a prefractionator, heavy benzene is directly extracted as a product, and light benzene enters a reflux tank and enters a reaction section by a high-speed pump. In order to filter impurities in the light benzene, a filter screen is arranged at the outlet of the high-speed pump to filter the impurities in the light benzene. The standby filter screen needs to be switched every time the filter screen is cleaned, the filter end socket is opened, 3 filter elements are removed, steam is used for blowing and sweeping for 2-3 hours on site, and the operation is troublesome and troublesome, and after cleaning and installation are finished, pressure is tested, the pressure during pressure testing is about 40-50 kilograms, and once leakage occurs, great potential safety hazards exist.
Disclosure of Invention
The utility model aims to solve the technical problem that a can avoid clearing up the filter screen at the high-pressure section is provided, and can effectively filter the impurity in the light benzene.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: benzene hydrogenation reaction section feeding filter equipment, including backward flow jar, canned pump, filter, pans, high-speed pump and automatically regulated valve, the both ends of canned pump are passed through the pipeline and are connected with backward flow jar and filter respectively, and the filter passes through the pipeline to be connected with the pans, and the pans passes through the pipeline to be connected with the high-speed pump, automatically regulated valve sets up on connecting tube one, and the pipe connection between the one end of connecting tube one and high-speed pump and pans, the other end of connecting tube one and the pipe connection of the piece of backward flow jar and canned pump.
Adopt the technical scheme of the utility model, can obtain following beneficial effect:
the utility model discloses a benzene hydrogenation reaction section feeding filter equipment can get rid of the impurity in the light benzene before the high-speed pump feeding, washs the filter screen, easy operation safety at the low pressure section. After this scheme is implemented, can remove the filter screen of high-speed pump export, can effectively satisfy the production demand, ensured safety in production. The scheme is simple and convenient to implement, economical and practical, production load is improved, economic benefits are improved, and safety production capacity is improved. Has wide popularization and use value.
Drawings
The contents of the description and the references in the drawings are briefly described as follows:
FIG. 1 is a schematic structural view of the apparatus;
the labels in the above figures are: 1. a reflux tank; 2. a canned pump; 3. a filter; 4. an intermediate tank; 5. a high-speed pump; 6. an automatic regulating valve.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, in which the shapes, structures, mutual positions and connection relationships of the respective members, the functions of the respective portions, the operation principles, and the like of the respective members are described.
As shown in figure 1, light benzene in the reflux tank 1 is sent to the intermediate tank 4 through the shield pump 2, in order to effectively filter impurities in the light benzene in a low-pressure section, a precision filter 3 is installed at the outlet of the shield pump 2, and the filter 3 is switched conveniently in an one-on-one-standby mode. The light benzene in the intermediate tank 4 is sent to the reaction section by a high-speed pump 5. In order to prevent the condition that the liquid level of the intermediate tank 4 is low because of the fault of the canned motor pump 2, an automatic regulating valve 6 is additionally arranged between the intermediate tank 4 and the high-speed pump 5, when the liquid level of the intermediate tank 4 is low and the inlet flow of the high-speed pump 5 cannot be met, the automatic regulating valve 6 is automatically opened, and the high-speed pump 5 is normally opened under the condition that the liquid level of the intermediate tank 4 is abnormal.
After the scheme is implemented, impurities in the light benzene can be removed before the feeding of the high-speed pump 5, the filter screen is cleaned at a low-pressure section, and the operation is simple and safe. After the transformation is implemented, the filter screen at the outlet of the high-speed pump 5 can be removed, the production requirement can be effectively met, and the safety production is guaranteed.
The scheme is simple and convenient to implement, economical and practical, production load is improved, economic benefits are improved, and safety production capacity is improved. Has wide popularization and use value.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
