The utility model provides a corrosion-resistant flame arrester suitable for a heat accumulating type oxidation incinerator, which belongs to the technical field of pressure conveying pipeline protection equipment, and comprises a flame arrester main body and a flame arresting element arranged in the flame arrester main body, the flame arresting element comprises an inlet layer, a transition layer and an outlet layer, the alloy compensation rings are arranged between the inlet layer and the transition layer as well as between the transition layer and the outlet layer, so that the gap can be automatically compensated under the condition of long-time high temperature through the alloy compensation rings arranged among the inlet layer, the transition layer and the outlet layer, and the influence of the change of the gap between the layers on the fire retardance effect of the flame arrester is avoided.

The utility model relates to a novel furnace end, including the fire cut seat and the fire cover, the fire cut seat is connected with the fire cover and forms the fire cut chamber, the fire cover includes the bottom ring part and the face shell part, is equipped with the connecting block between the bottom ring part and the face shell part, the connecting block is connected with the bottom ring part and the face shell part respectively and is fixed to make the bottom ring part and the face shell part form the gas outlet groove along the circumferential distribution between, the gas outlet groove is linked with the fire cut chamber, through setting the connecting block, can form the gas outlet groove on the fire cover, the fire cut chamber is even and sprays the gas outward through the gas outlet groove to the fire cover, thereby make the fire cover's fire effect more even, simultaneously, need not extra open multiple fire holes on the fire cover, has simplified the structure of the fire cover, makes the fire cover more beautiful.

The utility model relates to a novel furnace end which comprises a fire distributing seat and a fire cover, the fire distributing seat and the fire cover are connected to form a fire distributing cavity, a flow distributing piece is arranged at the position, corresponding to the position between the fire distributing seat and the fire cover, in the fire distributing cavity, the flow distributing piece is in an annular shape, and the fire distributing cavity forms an upper gas mixing layer and a lower gas mixing layer which are sequentially distributed from top to bottom through the flow distributing piece. The fire distribution base is provided with an air inlet, the flow distribution piece is tightly connected with the side, away from the air inlet, of the fire distribution cavity, the flow distribution piece and the side, close to the air inlet, of the fire distribution cavity form an air guide channel, and a first flow guide face capable of guiding airflow to flow from the side, away from the air inlet, of the fire distribution cavity to the side close to the air inlet is formed at the bottom of the flow distribution piece. The first flow guide face is of a continuous face-shaped structure without a perforated or hollowed-out area, the flow dividing piece can enable airflow to bypass in the lower gas mixing layer and then enter the upper gas mixing layer through the gas guide channel, and therefore gas in the upper gas mixing layer is distributed more evenly, and the better fire uniformizing effect is achieved.

The invention discloses a fresh-keeping process of a freshly stewed donkey-hide gelatin composition with an effect of preventing excessive internal heat. The fresh-keeping process comprises the following steps: extracting; carrying out rough filtration and fine filtration on the combined decoction, and carrying out nanofiltration by adopting nanofiltration equipment; melting glue; performing stewing; performing filling; and a nano composite film is used for covering and sealing. According to the method, through compatibility of traditional Chinese medicinal materials and donkey-hide gelatin, discomfort caused by poor taste when part of people eat the donkey-hide gelatin is enhanced, dryness of the donkey-hide gelatin is relieved, the risk of getting inflamed after eating is reduced, and meanwhile, the donkey-hide gelatin has the effects of preserving moisture, tightening, resisting wrinkles, brightening, whitening and removing freckles. In addition, the traditional Chinese medicinal material extracting solution of the freshly stewed donkey-hide gelatin is purified and concentrated by adopting a nanofiltration technology, and the packaging is sealed by adopting a composite membrane, so that the shelf life of the product can be effectively prolonged. Meanwhile, the invention also discloses application in food, medicine and health care products.

An electric fire apparatus (10) is provided, having an improved simulated fire effect. The electric fire apparatus (10) comprising a bed base (14a) which is at least in part light-transmissible. The electric fire apparatus (10) also has a holographic mesh element (18) as herein before defined which divides the bed base (14a) into a front bed base portion (42a) and a rear bed base portion (42b). At least one light source (50) is provided for directing light through the front and / or rear bed base portions(42a,42b).

The utility model provides a commercial gas furnace end which comprises an annular gas channel and a gas inlet pipe arranged on the annular gas channel in a penetrating mode, the interior of the gas inlet pipe is communicated with the interior of the annular gas channel at the joint of the gas inlet pipe and the annular gas channel, the first end of the gas inlet pipe is a gas inlet, and the second end of the gas inlet pipe at least extends to the middle of the annular gas channel. A plurality of gas outlet parts are distributed on the annular gas channel, the second end of the gas inlet pipe is also provided with the gas outlet parts, the gas outlet parts are in threaded connection with fire distributing heads, and the gas outlet parts are provided with spray heads communicated with the interiors of the fire distributing heads. According to the gas furnace end, the plurality of gas outlet parts are arranged on the annular gas channel and the second end of the gas inlet pipe, a high-pressure gas source is provided through the nozzles on the gas outlet parts, and gas is uniformly discharged from the high-pressure gas source through the fire distribution head, so that the gas furnace end obtains a strong fire effect, and the fire power is uniformly distributed, so that cookware can be quickly heated, and the energy consumption is reduced. However, over-fast loss caused by over-concentrated firepower is avoided.
