the utility model provides a hydrogenation unit reactor internals, including the barrel, the barrel upper end is provided with the end cover, it is provided with a plurality of hollow filter plates to extend its direction of height in the barrel, the filter plate outer fringe and the sliding seal contact of barrel inner wall, adjacent two filter plate insides communicate through communicating pipe, the filter plate upper end all is fixed with the endotheca rather than the coaxial axle, adjacent two filter plates pass through endotheca fixed connection, communicating pipe is located the endotheca inside, the filter mesh internal fixation of filter plate below has the filter screen, the inside packing of endotheca has the catalyst, be fixed with feed liquor pipe and drain pipe respectively on the filter plate of top and below, feed liquor pipe and drain pipe communicate with the inside of top and below filter plate respectively, the inside snakelike intake pipe of arranging of barrel lower extreme, the end cover upper end is fixed with the inside upper tube that communicates of barrel, the upper tube.

Specifically, the end cover is detachably and fixedly connected with the upper end of the cylinder body.

Specifically, feed liquor pipe and drain pipe all extend to the barrel outside, and the feed liquor pipe communicates with cold source feeding mechanism's export, drain pipe and cold source feeding mechanism's import intercommunication.

Specifically, the cold source supply device is a cooling water supply device.

Specifically, after the air inlet pipe is arranged in the barrel in a snake shape, two ends of the air inlet pipe respectively extend to the outside of the barrel.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses, moreover, the steam generator is simple in structure, high durability and convenient operation, arrange the catalyst in between endotheca and the filter plate, conveniently change the catalyst, the filter plate has cooling function simultaneously, can effectually walk the reaction heat, reduce the use length of cooling tube, increase the content of catalyst in the barrel, coolant passes through feed liquor pipe filter plate in the barrel and the operation from the top down communicating pipe, its cooling capacity reduces behind the coolant area reaches in the filter plate of below, consequently, the temperature of barrel below is higher, make the intake pipe pass through the barrel below, can make the heat of barrel below taken away promptly, can realize again simultaneously entering into the intake pipe in reaction gas's preheating.

Detailed Description

As shown in figure 1, the reactor internal part of the hydrogenation device comprises a cylinder body 1, wherein an end cover 11 is arranged at the upper end of the cylinder body 1, and the end cover 11 is detachably and fixedly connected with the upper end of the cylinder body 1. The cylinder body 1 is internally provided with a plurality of hollow filter plates 2 along the height direction thereof, the outer edges of the filter plates 2 are in sliding sealing contact with the inner wall of the cylinder body 1, the interiors of two adjacent filter plates 2 are communicated through a communicating pipe 3, the upper ends of the filter plates 2 are respectively fixed with an inner sleeve 4 which is coaxial with the filter plates, the two adjacent filter plates 2 are fixedly connected through the inner sleeves 4, the communicating pipe 3 is positioned in the inner sleeves 4, a filter screen 13 is fixed in a filter hole of the lowest filter plate 2, the inner sleeves 4 are filled with catalysts 5, the filter plates 2 above and below are respectively fixed with a liquid inlet pipe 6 and a liquid outlet pipe 7, the liquid inlet pipe 6 and the liquid outlet pipe 7 are respectively communicated with the, the liquid inlet pipe 6 and the liquid outlet pipe 7 both extend to the outside of the barrel body 1, the liquid inlet pipe 6 is communicated with an outlet of the cold source supply device, the liquid outlet pipe 7 is communicated with an inlet of the cold source supply device, and the cold source supply device is a cooling water supply device. The inside snakelike intake pipe 8 of having arranged of barrel 1 lower extreme, intake pipe 8 snakelike back of arranging in barrel 1, its both ends extend to barrel 1 outside respectively, and 11 upper ends of end cover are fixed with the upper tube 10 with the inside intercommunication of barrel 1, and upper tube 10 passes through connecting pipe 9 intercommunication with
