A urea hydrolysis decomposition device

Abstract

The invention relates to the technical field of chemical production, and discloses a urea hydrolysis decomposer device, comprising a hydrolysis reactor body, wherein the outlet end of the hydrolysis reactor body is connected with a product pipeline. The invention provides a heating sleeve on the surface of the product pipeline, thereby preventing the product from losing heat quickly during transportation, thereby causing the product in the product pipeline to easily generate gas condensation, thereby causing the hidden danger of pipeline blockage. Meanwhile, a clamping block and a clamping groove are provided inside a water storage tank, so that when there is no water accumulation in the heating sleeve, the pressure of the steam itself can be used to make the clamping block and the clamping groove seal and cooperate. When there is water accumulation in the heating sleeve, the water-bearing float can be used to make the clamping block and the clamping groove break away from the seal and cooperate, thereby achieving the effect of automatic dehydration, thereby avoiding the need for workers to frequently open and close a steam trap for drainage.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0021] See also Figure 1-3 A urea hydrolysis decomposer device comprises a hydrolysis reactor body 1, the outlet end of the hydrolysis reactor body 1 is connected to a product pipeline 2, the surface of the product pipeline 2 is connected to a heating sleeve 3, one side of the top of the heating sleeve 3 is connected to a steam inlet pipeline 4, the other side of the top of the heating sleeve 3 is connected to a steam outlet pipeline 5, the bottom of the heating sleeve 3 is connected to a connecting pipe 6, the bottom end of the connecting pipe 6 is connected to a water tank 7, the bottom of the water tank 7 is connected to a drain pipe 15, a chute 8 is provided on both sides of the inner cavity of the water tank 7, each chute 8 is slidably connected to a slider 9, and a float 10 is connected to the opposite side of the two sliders 9.

[0022] Among them, a support block 11 is connected between the two floats 10 through a fixing part, a clamping block 12 is connected to the bottom of the support block 11, a support plate 13 is connected between the two sides of the inner cavity of the water tank 7 and located at the bottom of the float 10, and a clamping groove 14 adapted to the clamping block 12 is opened on the top of the support plate 13. After the clamping block is inserted into the clamping groove, the outer peripheral surface of the support plate and the inner wall surface of the water tank form a sealed connection structure, which can achieve the sealing separation of the upper and lower parts of the water tank.

[0023] Preferably, the bottom of the inner cavity of the heating sleeve 3 is an inclined surface, wherein the float 10 is made of stainless steel and has excellent high temperature resistance.

[0024] As a preferred embodiment, a plurality of clamping blocks 12 are provided and are distributed equidistantly in a ring shape.

[0025] Further, in order to prevent the steam heat loss in the heating sleeve 3, the surface of the heating sleeve 3 is provided with high temperature resistant heat preservation cotton 16. The material of the high temperature resistant heat preservation cotton 16 is asbestos.

[0026] Furthermore, in order to prevent overpressure inside the heating sleeve 3 , the top of the heating sleeve 3 is connected to a vent pipe 17 , and a vent valve 18 is provided at the front of the vent pipe 17 .

[0027] Furthermore, in order to facilitate regular maintenance of the interior of the water storage tank 7 , a gate valve 19 is provided at the front of the connecting pipe 6 .

[0028] Furthermore, in order to provide support for the hydrolysis reactor body 1 , support columns 20 are connected to both sides of the bottom of the hydrolysis reactor body 1 , and a bottom plate 21 is connected to the bottom of the support columns 20 .

[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0030] During product transportation, superheated steam is injected into the heating sleeve 3 to ensure that the product pipeline 2 inside the heating sleeve 3 is always in a heated state, thereby avoiding the hidden danger of condensation of the product inside the product pipeline 2 due to rapid heat loss inside the product pipeline 2. When water condenses inside the heating sleeve 3 due to indirect contact with the outside air, the accumulated water will flow along the inclined surface inside the heating sleeve 3 to the inside of the connecting pipe 6, and then flow into the upper space of the support plate 13 of the water storage tank 7 through the connecting pipe 6.

[0031] As the accumulated water in the upper space of the support plate 13 inside the water tank 7 continues to rise, the float 10 will rise, and the rise of the float 10 will drive the support block 11 to rise, and the rise of the support block 11 will drive the block 12 and the slot 14 to disengage from the sealing fit. After the block 12 and the slot 14 disengage, the accumulated water will flow into the drain pipe 15 along the slot 14, and then flow to the outside through the drain pipe 15.

[0032] As the accumulated water in the water storage tank 7 is discharged, the support block 11 will descend and drive the clamping block 12 to seal and cooperate with the clamping groove 14 to store water.

[0033] The self-draining device provided inside the water storage tank 7 can reduce the labor intensity of workers frequently opening and closing the steam trap and reduce the problem of heat loss caused by opening the steam trap.
