Abstract
Provided is a sewage source heat pump system. The sewage source heat pump system is composed of a water source heat pump unit, an air conditioner system and an outdoor sewage source system. The outdoor sewage source system comprises a sewage pool, multiple sets of heat exchange tube banks, two sewage fetching wells, two sewage feed pumps and two sewage discharge pumps. The sewage source heat pump system takes urban untreated sewage as a cold and heat source, and due to the facts that the temperature of the urban untreated sewage can reach around 12 DEG C in winter, and the water temperature in summer is not high, the urban untreated sewage is the ideal cold and heat source of the water source heat pump unit. Therefore, a large quantity of primary energy resources can be saved, discharge of harmful gas can be further reduced, and therefore operation cost is low, and economic benefit is obvious.
Description
Technical field
The utility model relates to a kind of earth-source hot-pump system, particularly relates to a kind of sewage source heat pump system.
Background technology
Along with the raising of expanding economy and people's living standard, heating and the air conditioning of buildings such as public and dwelling house have become general requirement.Not only energy utilization rate is low as the coal-burning boiler of the traditional heat supply of China, but also can cause serious pollution to atmosphere, and therefore coal-burning boiler is progressively being eliminated in some cities, and fuel oil, gas fired-boiler then operating cost are very high.Particularly these systems all need use the primary energy that can't regenerate, so in order to save primary energy, at present just gradually by such as replacements such as earth-source hot-pump systems.Earth-source hot-pump system is that the novel energy that utilizes shallow-layer ground can carry out heating and refrigerating utilizes the eco-friendly power source of technology to utilize system.Wherein sewage source heat pump system is as Cooling and Heat Source with urban original wastewater, offer refrigerant in water source heat pump units with the mode of its cold by heat exchange summer, offer refrigerant in water source heat pump units with the mode of its heat by heat exchange winter, water source heat pump units will offer the air-conditioner that is installed in the interior space after will upgrading through the refrigerant of cooling after the heat exchange or intensification more afterwards, this refrigerant will carry out heat exchange with the air of the interior space in air-conditioner, thereby the interior space is remained under the suitable temperature.Being sewage source heat pump system is made up of the water source heat pump units that links to each other by pipeline each other, many air-conditioners that constitute air-conditioning system and outdoor source of sewage system, wherein water source heat pump units is installed in the machine room, mainly by compressor, condenser, expansion valve and evaporimeter by the be connected with each other refrigeration that constitutes or heat EGR and form of refrigerant pipe; Many air-conditioners are arranged on and need in the interior different interior spaces of thermoregulator building; Outdoor source of sewage system then is arranged on the urban original wastewater source nearby.
Sewage source heat pump system at present commonly used has two kinds of methods of operation, a kind of method of operation be by outdoor source of sewage system with urban original wastewater through directly feeding water source heat pump units after the filtration treatment, feed the condenser in the water source heat pump units during refrigeration; Feed the evaporimeter in the water source heat pump units when heating.Its advantage is that system architecture is simple, but shortcoming is very easily to stop up water source heat pump units, thereby causes heat exchange efficiency poor, therefore uses less in the actual engineering.The another kind of method of operation is to supply hot and cold to water source heat pump units indirectly by urban original wastewater, be that urban original wastewater carries out heat exchange by the intermediary's water that flows in heat exchanger and the heat exchanger earlier, provide cold and heat source to water source heat pump units indirectly by intermediary's water then.But there is following point in a kind of sewage source heat pump system in back: the complex structural designs of outdoor source of sewage system, so operating cost height, and inconvenient maintenance, and heat exchange efficiency is low.
Summary of the invention

In the described sewage intake well sewage feed pump around sewage filter net is installed, and an end that is positioned at sewage intake well inside on the sewage drainage pipe is positioned at sewage filter net.
The bottom surface of described cesspool tilts towards mud well direction for sleeping in, is convenient to mud in the cesspool like this and concentrates in the mud well that crouches and discharged by the sewage drainage pump.
Described sewage feed pump and sewage drainage pump are immersible pump.
Described sewage water inlet pipe in cesspool an end and the position of Wo Nijing antithesis.
The lower end of described heat exchange pipe is equipped with fixture, in case its position changes.
The sewage source heat pump system that the utility model provides is as Cooling and Heat Source with urban original wastewater, because the water temperature in urban original wastewater winter can reach about 12 ℃, and the water temperature in summer is not high yet, therefore be the very desirable Cooling and Heat Source of water source heat pump units, so not only can save primary energy in a large number, but also can reduce discharge of harmful gases, so operating cost is low, economic benefit is obvious.In addition, because many group heat exchange pipes are to be arranged in parallel, in case therefore certain group heat exchange pipe breaks down, only needing behind the valve closing with its two ends is replaceable or maintenance, need not the operation of halt system, so easy to maintenance, in addition, this sewage source heat pump system also has reasonable in design, simple, low cost and other advantages.
