Embodiment Construction

[0018] Below, the present invention will be described in further detail in conjunction with the accompanying drawings.

[0019] Such as Figure 1-2 As shown, in Embodiment 1, the bottom surface 11 adopts a one-sided inclination method, that is to say, the bottom surface 11 is a plane, which slopes downward from one side of the tank body 1 to the other side, so that the slag accumulation will move toward the lower side. Side accumulation forms a subsidence slag area. The air intake direction of the flushing device extends from the lower side to the higher side. The medium conveying main pipe 21 is T-shaped, and the air intake end is inserted into the tank from the side wall of the tank body 1. The flushing pipe 22 is arranged to extend horizontally from above the sedimentation slag accumulation area to the non-sedimentation area. Since the tank body 1 is cylindrical, the length of each flushing pipe 22 is determined according to its distance from the opposite side wall, and t...

Abstract

The invention discloses a self-slag-removing storage tank and an accumulated slag removing method thereof. A bottom structure of the storage tank is improved, a gaseous medium flushing device arrangedat the bottom is matched, and a corresponding accumulated slag extracting device and an accumulated slag conveying and treating device are arranged. The self-slag-removing storage tank and the accumulated slag removing method thereof can completely replace the traditional operation mode of manually opening the storage tank for cleaning, can be applied to tar and ammonia water storage tanks, can also expand the application field, and can be popularized to other types of liquid material storage tanks with sediment possibility. The problem of cleaning accumulated slag at the bottom of the tar and ammonia water storage tank is effectively solved, safety, environmental protection and occupational health risks caused by opening a manhole cleaning mode are avoided, and the passive situation thatcorresponding storage tanks must be stopped during cleaning brought to production is also avoided.

Description

technical field [0001] The invention relates to chemical storage equipment, in particular to a self-cleaning slag storage tank and a slag cleaning method thereof. Background technique [0002] In chemical production systems, liquid material storage tanks are widely used storage equipment. For example, a large number of ammonia and tar process products and final products in the coal chemical industry are stored in such tanks. The volume of these tanks ranges from tens of cubic meters to thousands of cubic meters. The basic structure is composed of tank bottom plate, side plate, tank roof and attached pipe joints, sides, manholes, and instrument interfaces. There are steam coils for insulation or heating. [0003] The tar and ammonia water produced in the coal chemical production process are basically a mixture of oil and water, containing a certain amount of coal coke dust, which is adsorbed together with the tar and ammonia water. After entering the storage tank, it settles...
