Background technology
Utilize underground water, surface water and sewage to have the important energy saving and the value of environmental protection for building provides heating and refrigeration as the Cooling and Heat Source of water resource heat pump, be to alleviate energy shortage, alleviate one of effective way of environmental pollution, winter, underground water, surface water and sewage enter the evaporimeter of water resource heat pump, reduce temperature, heat is extracted by water resource heat pump and sends in the building that needs heating; In summer, underground water, surface water and sewage enter in the evaporimeter of water resource heat pump, absorb from the heat temperature in the building to raise, because the heat in the building is absorbed, and temperature reduces, reach the purpose of refrigeration simultaneously.But need to solve problem how effectively to utilize various water sources.Sewage, surface water and underground water are after the process mechanical filter, still contain tiny particle, traditional flooded evaporator structure as shown in Figure 4, by housing 1, copper pipe 8, front tube sheet 10, back tube sheet 11 is formed, ante-chamber 12 end faces of housing are provided with water inlet 2, back cavity 13 end faces are provided with delivery port 7, the middle part is provided with refrigerant inlet 5 and refrigerant outlet 9, underground water when adopting the evaporimeter of this structure to use, surface water and sewage directly enter heat exchanger tube inside, because in use, heat exchanger tube inside has small dirt and produces, and causes tiny gravel to be deposited on being easy in the heat exchanger tube result in blockage and water resource heat pump can't normally be carried out.Although the silt content of underground water itself is also little, generally be no more than 20,000/, mechanicalness filters such as process sand cleaning machine can also be removed the bigger sand of particle about 80%, but because the water consumption of water source heat pump technology is very big, average every square metre of water consumption is between 50～100 tphs, this makes through the absolute quantity of the particles such as fine sand of water source heat pump system very big, and original flooded evaporator can not satisfy the requirement of water source heat pump technology stable operation.
Summary of the invention
The purpose of this utility model is for overcoming the weak point of prior art, design a kind of anti-sand type shell-tube full countercurrent flooded evaporator, can effectively stop particles such as sand in the underground water to enter heat exchange copper tube and cause the blockage problem of flooded evaporator.Can strengthen the phreatic extraction temperature difference, improve the energy that from underground water, is obtained, thereby reduce the water consumption of system greatly.
Anti-sand type shell-tube full countercurrent flooded evaporator of the present utility model comprises housing, many copper pipes, front tube sheet, back tube sheet; This housing is provided with water inlet, refrigerant inlet, delivery port and refrigerant outlet; This front tube sheet, back tube sheet are fixed in the housing, and space segmentation in the housing is become ante-chamber, lumen and back cavity; Water inlet and delivery port are separately positioned on the front end face and the rear end face of housing; It is characterized in that, also comprise sandboard, front end sediment ejection opening and rear end sediment ejection opening, this front end sediment ejection opening is arranged on the housing bottom of ante-chamber, and this sandboard is arranged in the ante-chamber, and between front tube sheet and front end sediment ejection opening, the rear end sediment ejection opening is arranged on the housing bottom of back cavity.The present invention can effectively stop the particles such as sand in the underground water to enter heat exchange copper tube and cause the blockage problem of flooded evaporator.Can strengthen the phreatic extraction temperature difference, improve the energy that from underground water, is obtained, thereby reduce the water consumption of system greatly.
Technical characterstic of the present utility model and effect
1. the utility model can effectively stop particles such as sand in the underground water to enter heat exchange copper tube and cause the blockage problem of flooded evaporator.And traditional common flooded evaporator can't address this problem, and must adopt settling pit or install plate type heat exchanger additional to form way such as secondary cycle and just can make the normal stable operation of water source heat pump system when using water source heat pump technology.But these ways can increase the investment of system on the one hand, can reduce the efficient of system again on the other hand and energy consumption is increased.
2. the utility model adopts full countercurrent heat exchange method can effectively improve heat exchange efficiency, can strengthen the phreatic extraction temperature difference under the prerequisite that does not reduce system effectiveness, improves the energy that is obtained from underground water, thereby reduces the water consumption of system greatly.

The specific embodiment
The anti-sand type shell-tube full countercurrent flooded evaporator of the utility model design reaches embodiment in conjunction with the accompanying drawings and is described in detail as follows:
Example structure of the present utility model as Figure 1-3, this anti-sand type shell-tube full countercurrent flooded evaporator comprises housing 1, many copper pipes 8, front tube sheet 10, back tube sheet 11; This housing is provided with water inlet 2, refrigerant inlet 5, delivery port 7 and refrigerant outlet 9; This front tube sheet 10, back tube sheet 11 are fixed in the housing, and space segmentation in the housing is become ante-chamber, lumen and back cavity; Water inlet 2 and delivery port 7 are separately positioned on the front end face and the rear end face of housing; The utility model is on the basis of above-mentioned traditional structure, also comprise sandboard 4, front end sediment ejection opening 3 and rear end sediment ejection opening 6, front end sediment ejection opening 3 is arranged on the housing bottom of ante-chamber, sandboard 4 is arranged in the ante-chamber, and between front tube sheet 10 and front end sediment ejection opening 3, rear end sediment ejection opening 6 is arranged on the housing bottom of back cavity.
Described front tube sheet 10 and back tube sheet 11 all have aperture, described copper pipe be arranged in the lumen and be fixed on before and after on the aperture on two tube sheets.
