Problems solved by technology

Its mechanical transmission, power and other equipment are many, the operation and maintenance are complicated, the failure rate is high, the labor intensity is high, and the pollution is also large
In recent years, some coking manufacturers in China have introduced unique or patented technologies such as Coopers and French Irh, and adopted the nozzle forming method, which has a good forming effect, but there are also disadvantages such as uncontrollable forming temperature, large investment, and high technology transfer fees.
[0005] The purpose of the present invention is to provide an improved asphalt form

Embodiment 1

[0031] Embodiment 1 (medium temperature asphalt forming):

[0032] The medium-temperature asphalt coming out of the high tank 1 has a temperature of 170°C to 180°C, and the flow rate is adjusted by the centrifugal forming pump 3 through the butterfly valve 5, and the mass flow rate is 11t / h. Asphalt is pumped into vaporization cooler 9 (horizontal type, with an area of ​​about 35m 2 ), where the bitumen is indirectly cooled by hot water. After the hot water absorbs the heat of the asphalt, it is vaporized and rises to the steam condenser 13 (vertical, with an area of ​​30m2) through the steam riser. 2 ), where the steam is condensed and cooled by cold water and returned to the evaporative cooler 9, the temperature of the return water is 80°C to 90°C, and the condensed water is recycled in a closed circuit to reduce scaling. The cooling water adopts the circulating water of the asphalt cooling pool, and a filter is installed at the inlet of the circulating pump. The water te...

Embodiment 2

[0034] Embodiment 2 (medium temperature asphalt forming):

[0035]The temperature of the medium-temperature asphalt coming out of the high tank 1 is 180° C. to 190° C., and the cooling control part of the asphalt is the same as in the first embodiment. The temperature of the medium-temperature asphalt coming out of the evaporative cooler is 145° C. to 155° C., and enters the nozzle shaper 16 . The nozzle is attached to the U-shaped main pipe of DN80 (see image 3 ), the front and rear rows of nozzles are staggered. The inner diameter of the nozzle outlet is 12mm, the length is 60mm, and the number is 14, forming an angle of 15° with the vertical downward direction. The front and rear adjacent rows of nozzles are arranged in a staggered manner, and the distance between the nozzles is evenly arranged according to the width of the chain plate.

Embodiment 3

[0036] Embodiment three (medium temperature asphalt forming):

[0037] The medium-temperature asphalt coming out of the high tank 1 has a temperature of 180°C to 200°C, and the flow rate is adjusted by the centrifugal forming pump 3 through the butterfly valve 5, and the mass flow rate is 10t / h. Asphalt is pumped into vaporization cooler 9 (horizontal type, with an area of ​​about 35m 2 ), where the bitumen is indirectly cooled by hot water. After the hot water absorbs the heat of the asphalt, it is vaporized and rises to the steam condenser 13 (vertical, with an area of ​​30m2) through the steam riser. 2 ), where the steam is condensed and cooled by cold water and returned to the evaporative cooler 9, the temperature of the return water is 80°C to 92°C, and the condensed water is recycled in a closed circuit to reduce scaling. The cooling water adopts the circulating water of the asphalt cooling pool, and a filter is installed at the inlet of the circulating pump. The wate...

Abstract

The invention discloses an asphalt forming method, comprising the steps of pressurizing and cooling liquid asphalt and then jetting the asphalt via a nozzle-type former for cooling formation. The invention also provides a system device for implementing the method. The device is mainly composed of a forming pump (3), a gasification cooler (9), a cooling coil (10), a steam condenser (13), the nozzle-type former (16) and a link plate conveyor (17), the cooling coil (10) is disposed in the gasification cooler (9), the steam condenser (13) is connected with the gasification cooler (9), the nozzle-type former (16) is connected with the end of the cooling coil (10) and is disposed above the link plate conveyer (17). The device is simple in process and convenient in operation, and pressurizes andcools the asphalt in a sealed system for formation so that the asphalt has quite small contact area with the air, thus can solve the problems such as inferior appearance, high moisture and serious pollution, etc. The cured asphalt is columnar in shape, uniform in thickness and almost solid and has water content not more than 5%, which accords with the national standards.

Description

technical field [0001] The invention relates to an asphalt forming method, in particular to a solid-state forming method of liquid medium-temperature asphalt or modified asphalt produced in the process of coal tar processing. The invention also relates to a system device for carrying out the asphalt forming method. Background technique [0002] The formation of tar pitch (medium temperature pitch or modified pitch) in China basically adopts the technology of the former Soviet Union in the 1950s, that is, the pitch from the high-set tank directly enters the feeder (discharge funnel) with several mesh holes at the bottom without cooling. ), the asphalt flows out from the sieve hole and flows to the chain conveyor that is immersed in water and moves. Due to the large surface area of ​​the feeder and the high temperature of the asphalt, a large amount of asphalt fume volatilizes. Even if there is a fume hood, the fume still escapes due to the need to open the cover for inspecti...
