Specific implementation mode

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

~3 are please referred to Fig.1, a kind of biogas dehumidification device is present embodiments provided, including:Air source heat pump 1, biogas conveying Portion 2.

Air source heat pump 1, the air source heat pump 1 have the condenser for the evaporator 11 of refrigeration and for heating 12, the evaporator 11 and condenser 12 are spiral fins pipe, specifically, the evaporator 11 and condenser 12 include One screw type tube body a and the fin b, the fin b for being fixedly connected on the spiral type pipe external surface increase the spiral The external surface area of type tube body a, to improve heat exchange efficiency.

Biogas delivery section 2 comprising condenser pipe 21, pressure inlet 22 and heating pipe 23, the inlet end of the pressure inlet 22 with 21 outlet side of the condenser pipe is connected, the outlet side of the pressure inlet 22 is connected with 23 inlet end of heating pipe;Specifically , the condenser pipe 21 includes air inlet pipe 211, condenser pipe body 212, drainpipe 213 and drain valve 214;The condenser pipe sheet The inlet end and the air inlet pipe 211 of condensation chamber 212a and water storage cavity 212b, the condensation chamber 212a are formed with inside body 212 Outlet side is connected, the outlet side of the condensation chamber 212a is connected with the inlet end of the pressure inlet 22;The evaporator 11 It is built in the condensation chamber 212a;The condenser pipe body 212 is arranged vertically;The water storage cavity 212b is by the condensation chamber 212a Lower end is downwardly extending;The drainpipe 213 is connected with the bottom of the water storage cavity 212b, and the drain valve 214 is installed In on the drainpipe 213, for opening and closing drainpipe 213, it is convenient for the condensed water being discharged in the water storage cavity 212b;The supercharging Pipe 22 includes a supercharging tube body 221, filter screen 222 and check valve 223, the inlet end of the supercharging tube body 221 with it is described The outlet side of condensation chamber 212a is connected, the outlet side of the supercharging tube body 221 is connected with the inlet end of the heating pipe 23 It is logical, and the internal diameter of the supercharging tube body 221 is less than the internal diameter of the condenser pipe body 212 and the heating pipe 23, caliber Become smaller, flow velocity is speeded so that the biogas in condenser pipe body 212 is transported in the form of spraying in heating pipe 23, avoids natural pond Gas reflux makes in the heat transfer to condenser pipe body 212 of heating pipe 23;The filter screen 222 is built in the supercharging tube body 221 close to one end of the condenser pipe body 212, and for filtering the impurity in biogas, 221 both ends of supercharging tube body are logical Flange (not shown) is crossed to connect with the inlet end of the outlet side of the condenser pipe body 212, the heating pipe 23 respectively, from And it is detachably pressurized tube body 221, it is cleaned convenient for the filter screen 222 to its inside;The check valve 223 is built in described Tube body 221 is pressurized close to the one end in the heating portion 23, further avoids the reflux of biogas.
