The invention relates to a double-atomization capturing electrostatic paint spray booth which comprises an electrostatic paint spray booth. An electrostatic spray nozzle is mounted in the electrostatic paint spray booth, a main water curtain plate and side water curtain plates are arranged on the inner wall of the electrostatic paint spray booth, a steam-water separation chamber is connected to the back of the main water curtain plate of the electrostatic paint spray booth, a bevel flushing plate is arranged on the lower portion of the main water curtain plate, the electrostatic paint spray booth is communicated with the steam-water separation chamber via a double-atomization paint mist capturing structure which is connected with the lower end of the bevel flushing plate, and a bottom plate flow guide structure is arranged at the bottom of the electrostatic paint spray booth. The double-atomization capturing electrostatic paint spray booth has the advantages that the double-atomization capturing electrostatic paint spray booth is simple in structure, scientific and reasonable in design, low in cost and high in paint mist capturing efficiency, and follow-up environmental protection treatment load can be effectively reduced.

The invention discloses an indoor air purifier. The indoor air purifier comprises a main case, a filter unit, a draught fan and an air exhaust device, wherein the filter unit and the draught fan are arranged in the main case, and the air exhaust device is arranged above the top of the main case. The top and the bottom of the main case are provided with openings. The two sides of the bottom of the main case are respectively provided with a support, so that the main case is suspended, and the opening in the bottom of the main case serves as an air inlet. The draught fan comprises a driving motor with two output shafts, wherein the driving motor is fixed into the main case, and the two output shafts of the driving motor are respectively connected with a wind wheel; a volute is arranged on the periphery of each wind wheel, and the upper end of each volute is communicated with the air exhaust device. Air can enter the bottom of the indoor air purifier at 360 degrees so that the requirement for large-area air purification can be met; air flow absorbed from the bottom can be exhausted from four sides of the top through the wind wheels on the two sides at the same time, and strong negative pressure is formed in an air flue, so more air can be absorbed in from the air inlet in the bottom, the adsorption capacity of the air inlet can be increased, more air can be filtered in a short time, the circulation speed of the air in a room can be increased to the maximum extent, and the efficient purifying effect can be achieved.

The invention relates to a large-sized workpiece electrostatic spraying booth. The large-sized workpiece electrostatic spraying booth comprises a spraying booth, wherein a first electrostatic nozzle and a second electrostatic nozzle are arranged in the spraying booth in a staggering manner; a workpiece inlet is formed in the spraying booth inner wall to which the first electrostatic nozzle correspond, and a workpiece outlet is formed in the spraying booth inner wall of the other side to which the second electrostatic nozzle correspond, so that a slideway passes the first electrostatic nozzle along the workpiece inlet and rotates one time, and then passes the second electrostatic nozzle and rotates one time to reach the workpiece outlet, thereby forming two rotation slideways; a first paint mist catching structure is arranged at the lower part of the spraying booth inner wall to which the first electrostatic nozzle correspond; and a second paint mist catching structure is arranged at the lower part of the spraying booth inner wall to which the second electrostatic nozzle correspond. The large-sized workpiece electrostatic spraying booth has the beneficial effects that the large-sized workpiece electrostatic spraying booth simultaneously performs the double-faced spraying operation of large-sized workpieces, is simple in structure, scientific and reasonable in design, small in floor space and low in cost, has high spraying efficiency and high paint mist washing efficiency and improves the treatment efficiency of follow-up organic waste gases.

The invention relates to a device (6) for pressure- dependent opening of a suction intake (10), comprising a suction jet pump (11), comprising a feed line (12), an outlet line (13) and the suction intake (10); a valve body (15), displaceably arranged inside the feed line (12) in the delivery direction (14) of the suction jet pump (11) and having an effective area (16) exposed to the feed pressure of the suction jet pump (11); and a spring element (17), arranged between the feed line (12) and the valve body (15), for applying a force in opposition to the feed pressure inside the feed line (12); wherein the effective area (16) of the valve body (15), and the spring element (17) are designed so that the valve body (15) closes the suction intake (10) so that it is fluid-tight below a predefined pressure inside the feed line (12) and opens said intake when the predefined pressure inside the feed line (12) is exceeded. The invention further relates to a fuel tank, comprising a device (6) for pressure-dependent opening of a suction intake (10).

The invention discloses a blowing cover fuel gas escape-preventing system and a control method thereof. The blowing cover fuel gas escape-preventing system comprises a blowing cover, a blowing pipe row and a gas pipeline and is characterized by further comprising an airflow device, wherein the blowing cover is positioned at the top of a sintering machine trolley; the blowing pipe row is arranged in the blowing cover, is positioned above the sintering machine trolley and is used for blowing combustible gas to the sintering material surface of the sintering machine trolley; the gas pipeline is used for conveying combustible gas to the blowing pipe row; the airflow device comprises a driving air cylinder and a rotary impeller device; and the rotary impeller device is arranged at the top of the blowing cover and is used for driving external air to generate airflow and conveying the generated airflow into the blowing cover downwards from the top of the blowing cover to form a wind pressurebelt area above the blowing pipe row, and combustible gas cannot penetrate through the wind pressure belt area upwards. The blowing cover fuel gas escape-preventing system can basically eliminates thefuel gas escaping phenomenon and can inhale the air out of the cover to further realize the purpose that a sintering production line produces stably, smoothly and excellently.
