Urea solution preparation box

Abstract

The invention discloses a urea solution preparation box, which comprises a urea solution preparation box body and a pyrolysis reactor, wherein the lower end of the urea preparation box body is provided with a buffer box; the inner wall of the buffer box is glidingly connected with a buffer plate; the lower end of the buffer plate is connected with the inner wall of the bottom of the buffer box through a plurality of buffer mechanisms; a plurality of support blocks are uniformly and fixedly connected onto the upper end of the buffer plate; the upper ends of the plurality of support blocks extend out of the buffer box through the opening and are fixedly connected onto the bottom of the urea solution preparation box; a plurality of buffer rubber rings are fixedly connected between the upper end of the buffer plate and the inner wall of the top of the buffer box; a plurality of buffer springs are uniformly and fixedly connected between the upper end of the buffer box and the lower end of the urea solution preparation box body. The problems that in the work process of the urea solution preparation box, the vibration is liable to influence the stable placement of the solution preparationbox, or even damages the solution preparation box can be effectively solved, so that the decomposition of the urea solution is more thorough and faster.

Description

technical field [0001] The invention relates to the technical field of ammonia production equipment, in particular to a urea solution preparation tank. Background technique [0002] As a non-hazardous raw material for ammonia production, urea pyrolysis ammonia has the same denitrification performance as liquid ammonia. Urea is a green fertilizer and non-toxic, so there are no regulatory restrictions, and it is easy to transport, store and use. At present, it has become a trend to use urea as the reducing agent in SCR denitrification in China. [0003] The current urea solution preparation box includes a urea solution preparation box and a pyrolysis reactor, wherein the urea solution preparation box will produce a certain vibration during operation, which not only makes the placement of the urea solution preparation box not stable enough, but also causes damage to the urea solution preparation box. The damage caused by the movement, and the urea solution preparation tank is ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the urea solution preparation box in the prior art will produce a certain vibration during work, which not only makes the placement of the urea solution preparation box not stable enough, but also causes damage to the urea solution preparation box. The solution preparation box is connected to the atomizing nozzle in the pyrolysis reactor. The spraying range of the atomizing nozzle is fixed, and more urea solution will accumulate in a unit volume, which cannot make the urea solution decompose faster and better to produce ammonia, which is not convenient for people. The problem of using a urea solution preparation box while presenting
