The invention relates to a preparation and application method of an ozone-enhanced catalytic material, specifically boron-modified mesoporous carbon airgel loaded with Fe 2 o 3 and C O3 o 4 Ozone-enhanced catalytic materials, adding boric acid and iron solution to the raw materials to obtain boron-modified iron-loaded mesoporous carbon airgel precursors, and aerogels obtained under the protection of argon, as C O3 o 4 The carrier, under capillary action, tricobalt tetroxide penetrates into the interior of the carbon airgel gap, and obtains a boron-modified mesoporous carbon airgel catalyst loaded with iron and tricobalt tetroxide. Bubbles, hydrogen peroxide or ozone microbubbles / hydrogen peroxide are fully mixed with wastewater, fully contacted on the surface of boron-modified loaded iron and tricobalt tetroxide mesoporous carbon airgel catalyst, and generate a large number of hydroxyl radicals to further treat organic pollutants in water. The invention has the characteristics of large specific surface area, high porosity, etc., and has high-efficiency catalytic characteristics under the synergistic catalytic action of iron and cobalt.

The invention relates to a differential deep water blowout preventer control valve, which belongs to the field of deep water oil drilling equipment. The differential deep water blowout preventer control valve comprises an electromagnetic control valve and a guide valve, wherein the electromagnetic control valve is arranged inside the guide valve; an electromagnetic control module is fixed inside the electromagnetic control valve; the valve body of the electromagnetic control valve is provided with three oil channels; and the make-and-break of the oil channels are controlled through the position of a valve core arranged on the junction of the three oil channels. The differential deep water blowout preventer control valve has the advantages: a differential structure is formed by the lower end of the valve core of the electromagnetic control valve and the upper end of an iron core under the action of a high-pressure working fluid simultaneously, so that the problem of the influences of excessively high rigidity requirement of a spring and the pressure fluctuation of the working fluid during the use of the high-pressure working fluid on the static performance of the electromagnetic control valve can be solved. Working pressures are applied to the two ends of the iron core and the valve core of the electromagnetic control valve, so that the response speed of an entire hydraulic control system can be increased, and convenience is brought to modular installation; and most materials of the valve body are made of stainless steel, so that high corrosion resistance is achieved, work is reliable, and the service life is long.

The present invention proposes a solid substrate for plant growth, which uses Chinese fir chips as the main component, which will produce juice under heating conditions and be bonded to each other without adding additional adhesives to form a solid substrate in the form of a compressed block, which is convenient for handling and modules It can also inhibit the growth of plant roots and prolong the service life of the solid substrate; in addition, the fir chips are slowly fermented during use and slowly release nutrients, which can control the growth rate of plants and prolong the life of the solid substrate. Service life; adding charcoal powder can inhibit mold and disinfect; by controlling the proportion and particle size of fir sawdust and charcoal powder, the overall solid matrix can maintain a suitable water retention rate, which can provide sufficient water retention while ensuring ventilation. A large amount of water is used for plant growth; adding inhibitors slows down the fermentation speed and slowly releases nutrients, which can control the growth rate of plants and prolong the service life of the solid substrate.

The invention discloses a building electrical cabinet convenient to overhaul and replace. The building electrical cabinet comprises an electrical cabinet body, a mounting mechanism arranged in the electrical cabinet body and a supporting mechanism arranged at the bottom of the electrical cabinet body. And the mounting mechanism comprises a mounting plate arranged in the electrical cabinet body and a transverse plate which is detachably mounted on the mounting plate and is used for mounting various electrical elements. The mounting plate, the transverse plate, the mounting hole groups, the mounting grooves formed in the transverse plate and the mounting screws facilitate detachable arrangement of the transverse plate on the mounting plate, and meanwhile, the transverse plate with a proper size can be selected for mounting according to needs, so that modular mounting and replacement of the element group of the electrical cabinet are facilitated; the purposes of facilitating timely maintenance of the equipment, improving the maintenance efficiency of the electrical cabinet and ensuring the use quality of the electrical cabinet are achieved.

The short pipes are connected between the reactor and the steam generator, between the steam generator andthe main pump and between the main pump and the reactor. The structure has the advantages of being compact in structure and high in pipeline safety, and occupies small space.

The invention belongs to the field of related equipment of the carbon capture technology and particularly relates to a rotary cyclic carbon capture device and method based on three-bed reaction. The rotary cyclic carbon capture device comprises a rotating shaft and one or more sets of circulatory reaction units, wherein each set of circulatory reaction unit comprises three reactors which are arranged side by side in the circumferential direction of the rotating shaft and are uniformly distributed; a cavity is formed in each reactor and used for placing an absorbent; a gas inlet is formed in the top of each reactor; a gas outlet is formed in the bottom of each reactor; and each gas inlet and the corresponding gas outlet are communicated with the cavity in the corresponding reactor. The invention further discloses a method adopting the rotary cyclic carbon capture device to perform circulatory carbon capture. The problem of adsorption performance degradation caused by the reasons that pores are reduced by high-temperature sintering of a calcium-based absorbent and the pore structures are destroyed by CaSO4 impurities generated by a SO2 reaction is solved, meanwhile, the problem of abrasion of an absorbent is solved, the energy consumption is greatly reduced, and the rotary cyclic carbon capture device is compact in structure and has the advantages of high economical efficiency, excellent environmental friendliness and the like.
