It catalyst recovery devices technical characterstic in the utility model production of biodiesel and has the beneficial effect that:

1. esterification catalyst can utmostly be recycled, not waste of resource, the influence to environment is reduced；

2. the apparatus structure is simple, easy to operate；

3. the device recycles catalyst, low energy consumption；

4. corrective maintenance is simple, maintenance cost is low.

Detailed description of the invention

Fig. 1 is the catalyst recovery devices structural schematic diagram in the utility model production of biodiesel.

Appended drawing reference: separation addition agent storage tank 1, control valve 3,1# pump 4, knockout drum 5, row's oil slick valve 6, is floated at flowmeter 2 Oily receiving slit 7, impurity receiving slit 9,2# pump 10, batching kettle 11, fresh catalyst feed pipe 12,3# pump 13, is urged at impurities removal valve 8 Agent storage tank 14.

Specific embodiment

With reference to the accompanying drawings and detailed description to the catalyst recovery devices in the utility model production of biodiesel It is described in further detail.

Shown in Fig. 1, the catalyst recovery devices in the utility model production of biodiesel include one group of separator and one Group esterification catalyst compositional apparatus, the two are connected in series；The separator includes separation addition agent storage tank 1, flowmeter 2, adjusts Valve 3,1# pump 4, knockout drum 5, row's oil slick valve 6, oil slick receiving slit 7, impurities removal valve 8 and impurity receiving slit 9, the separation auxiliary agent Flowmeter 2 and control valve 3 are installed in the bottom pipe of storage tank 1 and are connected on the inlet pipeline of 1# pump 4,1# pump 4 goes out Mouth pipeline is connected to the top of knockout drum 5, and the side upper pipe of knockout drum 5 is equipped with row's oil slick valve 6 and is connected to oil slick and connects Slot 7 is received, 5 bottom of knockout drum is equipped with impurities removal valve 8, and the lower part of impurities removal valve 8 is equipped with impurity receiving slit 9；The esterification catalyst Compositional apparatus includes 2# pump 10, batching kettle 11 and fresh catalyst feed pipe 12 with stirring, and the import of 2# pump 10 is connected with pipeline It is connected to the side lower part of knockout drum 5, the outlet conduit of 2# pump 10 is connected to the top of batching kettle 11, and the top of the batching kettle 11 is equipped with Fresh catalyst feed pipe 12；The bottom of the batching kettle 11 connects the import of 3# pump 13, the outlet warp of 3# pump 13 by pipeline Pipeline is connected to the top of catalyst storage tank 14.
