The invention discloses a gas-liquid separation device, which comprises a film sulfonation reactor, a gas-liquid separator and a separator. An inlet of the film sulfonation reactor is connected to a feed pipeline. The gas-liquid separator contains a first inlet and a second inlet, wherein the first inlet is communicated with an outlet of the sulfonation reactor. An inlet of a settling separator is communicated with an outlet of the gas-liquid separator through a first pipe section group, and an outlet of the settling separator is communicated with the second inlet. The settling separator receives tail gas obtained after primary separation by the gas-liquid separator and carries out secondary gas-liquid separation on the tail gas. The gas-liquid separator receives a separation liquid obtained after the secondary gas-liquid separation. The invention also discloses a separation liquid recovery method by using the above gas-liquid separation device.

The invention discloses a manufacturing method of a high abrasion-resistant slurry nozzle. The manufacturing method comprises the following steps of (1) blanking processing, (2) laser cladding, specifically, laser cladding comprises (1) nozzle external surface treatment and (2) nozzle internal hole treatment, (3) nozzle finishing, specifically, nozzle finishing comprises (1) nozzle external surface treatment and (2) nozzle internal hole treatment, (4) nozzle checking, and (5) nozzle assembly assembling. According to the technical scheme of the manufacturing method of the high abrasion-resistant slurry nozzle, the unique manufacturing method is adopted, through a laser cladding technology and based on the advantage that combination of abrasion-resistant materials formulas is convenient, thefact that an easy-to-process high temperature-resistant material matrix is clad with a cladding layer with good high temperature resistance and excellent abrasion resistance in the process of nozzlemanufacturing is achieved, so that the abrasion resistance of a nozzle internal hole is better, the service life of the nozzle is prolonged, the foundation is laid for safety, economy and long periodstability of a device, and the economic benefit is improved.

Disclosed is a foldable bumper of a motorcycle. A fixed bumper frame, a left protection bumper frame and a right protection bumper frame of the bumper are in independent structure formed independently, the left protection bumper frame and the right protection bumper frame are rotationally mounted on the fixed bumper frame through hinge shafts, positioning blocks used for positioning rotationally are arranged on the left protection bumper frame and the right protection bumper frame respectively, each positioning block is provided with an unfolding positioning hole and a folding positioning hole, two locking devices used for locking the rotation positions of the left protection bumper frame and the right protection bumper frame are arranged on an upper transverse pipe of the fixed bumper frame, fixed seats of the locking devices are fixedly welded on the fixed bumper frame, positioning latches with bent ends are mounted vertically rotationally on the fixed seats through pins and inserted into the positioning holes on the positioning blocks and stay at normal locking state under the pressure of a reset spring. The left protection bumper frame and the right protection bumper frame of the bumper can be unfolded or folded, have protection action during running of the motorcycle or can reduce occupation space during parking, partial parts of the bumper can be replaced respectively, maintenance and replacement cost can be reduced, and the locking devices are not easy to be damaged.

The invention discloses a seawater corrosion-resistant titanium tube outboard cooler, which comprises an end cover and a tube plate fixedly connected to the bottom of the end cover, the inner cavity of the tube plate is provided with a cooling pipe, and the two sides of the upper end surface of the end cover are respectively There are two flanges in communication, and the two flanges are connected with the cooling pipe. The center of the lower end surface of the end cover is provided with a limiting groove, and the inner cavity of the limiting groove is slidably connected with a rotating sleeve. The two sides of the rotating sleeve Both are fixedly connected with an inner casing, the inner casing is slidably connected with the cooling pipe, and the cooling pipe is respectively rotatably connected with the first gear capstan and the second gear capstan. In the present invention, the titanium tube structure is adopted to realize that the tube wall of the titanium tube is thinner than the copper tube, further reducing the weight of the cooling tube, and a rotating impurity removal structure is adopted to realize friction scraping and cleaning of the outer wall of the cooling tube. A two-way anti-helical structure is adopted to achieve an enhanced scraping effect on impurities on the outer wall of the cooling tube.

The invention provides a bidirectional-driving disconnector, comprising a first contact arm, a second contact arm and a driving mechanism, wherein the first contact arm is suitable to be connected with a first contact electrically; the second contact arm is suitable to be connected with a second contact electrically and has a second contact part; the first contact and the second contact are a pair of moving contact and fixed contact which are arranged oppositely; the driving mechanism is used for driving the first contact arm to move along the axial direction of the driving mechanism so as to enable the first contact part to be connected with or disconnected from an external circuit and also for driving the second contact arm to move along the axial direction of the driving mechanism so as to enable the second contact part to be connected with or disconnected from the external circuit. Compared with the prior art, the bidirectional-driving disconnector occupies less space, facilitates the miniaturization and compactness of equipment; since two obvious disconnection points occur when in a disconnected state, the bidirectional-driving disconnector, compared with a disconnector in the prior art, has the advantage of high safety performance.
