A novel flue-gas waste-heat recycling system comprises a flue-gas heat exchanger, a water inlet pipe, a water outlet pipe, a water tank, a refrigerant medium water pump and a waste-heat using device and further comprises a secondary heat exchanger. The secondary heat exchanger further comprises a secondary heat exchanger casing and a secondary heat exchanger pipe arranged in the secondary heat exchanger casing. The flue-gas heat exchanger is a module type fluorine plastic pipe flue-gas heat exchanger, and positioning meshes are parallelly distributed in a flue-gas heat exchanger casing of the flue-gas heat exchanger at intervals from top to bottom. The novel flue-gas waste-heat recycling system avoids pollution of a finally-heated medium, and the using of the final waste-heat using device is not influenced. The flue-gas heat exchanger is the module type fluorine plastic pipe flue-gas heat exchanger, and accordingly the flue-gas heat exchanger is easy to operate and manage. The positioning meshes are arranged in the module type fluorine plastic pipe flue-gas heat exchanger, and shaking and deformation of a flexible fluorine plastic heat exchange pipe bundle under the flowing impact of flue gas can be avoided.

The invention discloses a condenser. The condenser comprises a condenser body which is provided with an open cavity, wherein a cover plate which is arranged at an opening of the open cavity and is used for sealing the open cavity is fixedly arranged on the condenser body, the open cavity consists of a liquid inlet chamber, a liquid through chamber and a liquid outlet chamber which are sequentially distributed from front to back, a liquid inlet hole communicated with the liquid inlet chamber and a liquid outlet hole communicated with the liquid outlet chamber are formed in the cover plate, and a plurality of flow blocking bulges which are densely distributed in the liquid through chamber and are of staggered distribution are formed on the condenser body. The condenser disclosed by the invention is light and small in body type and extremely high in condensing efficiency.

The invention discloses an explosion-proof valve anti-flaming ring. The ring comprises an anti-flaming ring boy and is characterized in that the anti-flaming ring body comprises a ring part and boss shoulders arranged on the ring part in a matched manner, the boss shoulders are evenly arranged along the circumference of the ring part, the cross section of the ring part is of a right hexagonal structure, a six-edge ring structure with the cross section in the right hexagonal shape is adopted in each boss shoulder, the radius of the anti-flaming ring body can be correspondingly adjusted throughthe size of the ring part, adjacent anti-flaming ring bodies with different radiuses can be in fit pressing connection through the side faces of the boss shoulders and the side face of the ring part,and the anti-flaming ring layer is formed. According to the anti-flaming ring, according to work requirements, the number of layers of anti-flaming rings can be adjusted, mounting flexibility is large, the shape is simple, production is easy, and production efficiency is high.

The invention discloses a flame-retardant type anti-explosion valve of a crankcase. The flame-retardant type anti-explosion valve of a crankcase comprises a valve deck and a valve seat. A valve clackis arranged on the valve seat. An inner flame-retardant ring group, an outer flame-retardant ring and a spring are arranged between the valve deck and the valve seat. The upper end of the spring is fixed to the valve deck. The lower end of the spring tightly presses the valve clack. The inner flame-retardant ring group and the outer flame-retardant ring are arranged in the space formed by the valve deck and the valve seat to form a flame retardant device. Because the flame-retardant type anti-explosion valve of a crankcase is adopted, the airflow through holes of the valve are evenly distributed along the surfaces of ring bodies, the airflow through holes of the same ring body are evenly arranged side by side, the airflow through holes of two adjacent ring bodies stagger to form labyrinthtype bend channels, the time for airflow and flames to pass through can be effectively prolonged while heat exchange between airflow and the inner walls of the flame retardant rings can be sufficient,the use ratio of the flame retardant rings is increased to the maximum degree, the temperature is lowered, and the purposes of reducing pressure and putting out flames are achieved finally. The flame-retardant type anti-explosion valve of a crankcase is simple in structure, and easy to produce and install. The problems exist in an anti-explosion valve can be solved. The flame-retardant type anti-explosion valve of a crankcase has broad application prospects.
