High-efficiency tilted plate sand-removal and water-intake device

The invention relates to a high-efficiency tilted plate sand-removal and water-intake device which is used as water intake equipment in water supply engineering and surface water source heat pump engineering. The device comprises a water inlet chamber, a sand-separating and self-cleaning chamber and a water outlet chamber, wherein the wall of the intake chamber is made of corrugated bent plates and is provided with countless water inlet holes and water inlet/sand discharge dual-purpose holes; and the upper half of the sand-separating and self-cleaning chamber is a sand-separating chamber, the lower half is connected with a self-cleaning sand discharge bucket and a sand discharge pipe, a plurality of lateral flow tilted plates are arranged in bilateral symmetry in the direction of water flow in the sand-separating chamber, the tilted plates are tilted downwards and are provided with fins which are perpendicular to the direction of water flow and the plane of the tilted plates, and a sand-settling channel is left in the symmetry axis position of left and right lateral flow tilted plates and is communicated with the self-cleaning sand discharge bucket at the lower part. The device can be widely used in rivers having a high floater and sand content, and can be also used in water intake engineering using lakes, reservoirs or other water bodies as the water source. Besides, the device can effectively prevent the blocking of weeds and other floaters in water, effectively remove sand in water, omit the special sand basin and simplify the subsequent water treatment process, thereby achieving the purposes of reducing the abrasion of water pump impellers and subsequent water treatment structures, saving the capital investment, saving the occupied area and lowering the water intaking cost.

Water taking system for shallow water river in water-depleted mountainous area

The invention discloses a water taking system for a shallow water river in a water-depleted mountainous area. The system involves an overflow weir, a water taking chamber and a radiation well, whereina spillway grid is arranged at an inlet of the water taking chamber, a floating mushroom head automatic water taking device and an on-line turbidity meter are arranged in the water taking chamber, and a submersible pump is arranged in the radiation well. When flooding does not occur, the overflow weir lifts the water level of the shallow water river, river water flows into the water taking chamber through the spillway grid, and then enters a water conveying pipe from the floating mushroom head automatic water taking device to flow to the radiation well, and finally, the submersible pump conveys the river water to a subsequent water purifying structure; a drought period relies on joint recharge of the above mentioned surface water recharge mode and the seepage of the radiation well; when the on-line turbidity meter in the water taking chamber during a flood period is displayed higher than 5 NTU, the on-line turbidity meter feeds back a signal to a self-control system, an electric butterfly valve mounted on the water conveying pipe is closed, and the radiation well supplies water through the self-seepage; according to the water taking system, the water supply amount of the shallow water river in the water-depleted mountainous area can be ensured, the water quality is reliable, the service life of the water taking system is prolonged, and the water taking cost is reduced.

Equipment for obtaining water from air

Equipment for obtaining water from air comprises a fan, a compressor, a condenser and an evaporator, wherein a power supply is arranged according to the equipment. The equipment is characterized in that a centrifugal fan is arranged at an inlet of a high-efficiency filter; an air box is communicated with the high-efficiency filter; a cross-flow plate and the evaporator are arranged in the air box;the evaporator is provided with a water tank, an expansion valve and an electromagnetic valve, the refrigeration compressor is connected with the evaporator and the condenser, and the condenser is provided with an axial flow fan. The operation power is converted according to the formula that the water obtaining amount per hour is equal to the product of processing air volume, the air density andthe moisture content difference. The equipment is an electric device capable of directly condensing air to obtain water, the high-efficiency filter firstly purifies air sent by the fan, wet air is introduced into the evaporator through the fan, the temperature of the evaporator is low and accordingly the air is forced to be saturated and separated out, and the water is gathered in a water collecting disc and flows into a water storage tank. The equipment is small in size, integrated in design and simple in structure, is not limited by conditions, meets the requirement of team stationing and scattered outworkers for domestic water, and solves the problem about water application during outdoor activities.
