City native sewage water and intelligent type sewage water block prevention machine of earth's surface water source heat pump system

Abstract

The invention relates to a device which prevents heat exchange equipment from blocking when the urban raw sewage, surface water (such as river water, sea water, etc.) are adopted as heat pump low cool and heat sources. The device of the invention is composed of a frequency-variable motor (1), a secondary reducer (2), a shell (3), a control cabinet (14), a rotating filtering cartridge (12), an inner cylinder inlet (8), an inner cylinder outlet (10), an outer cylinder inlet (4), an outlet cylinder outlet (5), a water outflow adjusting plate (19).

Description

technical field [0001] The invention relates to a device for preventing blockage of heat exchange equipment when urban primary sewage and surface water sources (rivers, lakes, sea water, etc.) are used as low-level cold and heat sources of a heat pump. Background technique [0002] Energy is an important material basis for the survival and development of human society, and finding and utilizing new renewable energy is an effective way to solve energy shortages. The development and utilization of urban raw sewage and surface water sources as heat pump cold and heat sources for heating and air conditioning of buildings has important energy-saving and environmental protection values, and is of great significance to alleviating energy consumption and environmental pollution, but it is necessary to effectively and economically solve the technical problems of water sources. When using urban raw sewage and surface water, the main technical problem is that the heat exchange equipmen...

Problems solved by technology

When using urban raw sewage and surface water, the main technical problem is that the heat exchange equipment is blocked by dirt and debris, and the system cannot operate normally. How to solve the problem of blockage has become a technical problem

[0003] The invention patent with the patent number ZL200610010437.9 provides a non-blocking pressure balance anti-blocking device. The outer shell of the anti-blocking device is provided with an outer water inlet and an outer drain, and the rotating filter cartridge is arranged inside the outer shell. , the interior of the rotary filter cartridge is divided into the water inlet area and the water outlet area in the cylinder, and the water inlet area in the cylinder is connected with the inlet of the water outlet area in the cylinder. The main performance parameters of the equipment, flow rate, temperature, and pressure cannot be displayed and read normally, and the operating conditions of the equipment cannot be adjusted according to the operating data; the rotation speed adjustment of the rotary filter cartridge is not an accurate value; The net is vertical, so that some filamentary dirt is directly attached to the side wall of the rotary filter screen under the punching pressure of the incoming water, and the combination of the filamentary dirt and the rotary filter screen is relatively tight due to the direct impact of the water pressure. Difficult to rinse, when the time is long, the filamentous dirt accumulates, and the filter is easily blocked by the filter port
