Abstract
A coal-gasification furnace-chilled ring rotation water-injection strengthening cooling is a strengthening coal-gasification furnace-chilled indoor heat and mass transfer device, including a chilled ring (1), a incurrent canal (2), a inclined spiracle (3), a groove slit with ring shape (4) and a drop tube (5); Among the mentioned above, the chilled ring (1) is a loop tube shape, and the inner round side of the chilled ring (1) is provided with the inclined spiracle (3). The inclined spiracle (3) is arranged with a uniform distribution along the inner circumference of the chilled ring (1). The role of the inclined spiracle (3) is to produce along the helix hand a downward flowing of the cooling water from a inclined hole and the syngas with vertical downward flowing from the drop tube; The inclined direction of the inclined spiracle (3) regards the medial axis of the chilled ring (1) as a shaft with a distribution of a clockwise or anticlockwise direction.
Description
Technical field
The utility model is that a kind of coal gasifier shock chamber strengthens the refrigerative apparatus and method.Belong to the technical field that the vapourizing furnace refrigerating unit is made.
Background technology
As a kind of coal gasification method, coal burns under anoxia condition and produces high temperature crude synthesis gas and molten state lime-ash in coal gasifier, enters the shock chamber then.The shock chamber mainly is made of chilling ring and downtake; chilling ring is positioned at the downtake top; water coolant flows along the downtake inwall from top to bottom by chilling ring, forms moisture film at the downtake inwall, its objective is in order synthetic gas to be carried out Quench and to protect downtake not burnt out by high-temperature gas.
The purpose of shock chamber is for synthetic gas is cooled off fast, and there is substantial connection the contact area of the heat-transfer intensity of process of cooling and synthetic gas and water coolant and the synthetic gas residence time in downtake, synthetic gas in the downtake is from top to bottom at present, linearly flowing, mainly is to contact by the moisture film with the downtake inwall with the contacted chance of water coolant.For increasing the contact area of synthetic gas and water coolant, also there is employing on chilling ring, to have spout hole, water is vertically sprayed to synthetic gas by chilling ring, to reach the reinforcement cooling purpose.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of coal gasifier chilling ring rotation water spray and strengthens refrigerating unit, this device can increase the contact area of synthetic gas and water, increased synthetic gas flow process in downtake simultaneously, increase the residence time of synthetic gas in downtake, and to restraining the fracture generation effect of downtake inwall moisture film, making conducts heat is strengthened.
Technical scheme: according to above-mentioned introduction with analyze as seen, the contact area and the growth residence time of synthetic gas in downtake that increase synthetic gas and water coolant all can increase heat-transfer intensity, if at the chilling ring place along certain circumferential interval, on horizontal plane with water coolant and radius at an angle direction spray to synthetic gas, make synthetic gas in the downtake under the effect that sprays into water droplet, flow downward along the hand of spiral, this can increase the contact area of synthetic gas and water on the one hand, increased synthetic gas flow process in downtake simultaneously, increased the residence time of synthetic gas in downtake, in addition, spiral air flow has the supression effect to the fracture of downtake inwall moisture film, and making conducts heat is strengthened.
Coal gasifier chilling ring rotation water spray of the present utility model is strengthened refrigerating unit and is comprised chilling ring, inhalent siphon, inclination spout hole, annular slot, downtake; Chilling ring is a belt tubulose, the circle side has the inclination spout hole in chilling ring, the inclination spout hole along the chilling ring inner periphery to uniform distribution, the effect of inclination spout hole is to make in the water coolant that sprayed by inclined hole and the downtake vertically downward that the mobile synthetic gas produces flowing downward along the hand of spiral, annular slot is located at the chilling ring downside, is positioned at the inboard of downtake simultaneously.The vergence direction of inclination spout hole is rotating shaft with the axis of chilling ring, is clockwise direction or arrangement counterclockwise.The mobile synthetic gas carries out momentum exchange vertically downward from the water coolant of inclined hole ejection and downtake, makes cooling water droplet and mobile circle of contact of synthetic gas formation in the downtake to cause synthetic gas to flow downward along the hand of spiral.Because it is very little to spray into the drop diameter of synthetic gas, therefore have very big specific surface area, the touch opportunity that this can increase synthetic gas and water has on the one hand increased synthetic gas flow process in downtake simultaneously, increased the residence time of synthetic gas in downtake, making conducts heat is strengthened.
Beneficial effect: this utility model can not increase shock chamber's height, not increase under the situation of manufacturing cost of shock chamber, increase the contact area of synthetic gas and water greatly, increase synthetic gas flow process and synthetic gas residence time in downtake in downtake, and to restraining the fracture generation effect of downtake inwall moisture film, making conducts heat is strengthened.
Description of drawings
Fig. 1 is the structural representation that the utility model coal gasifier chilling ring rotation water spray is strengthened refrigerating unit.
Fig. 2 is the sectional structure synoptic diagram of chilling ring 1 among Fig. 1.
Wherein have: chilling ring 1, inhalent siphon 2, inclination spout hole 3, annular slot 4, downtake 5.
Embodiment
The utility model is that a kind of coal gasifier chilling ring rotation water spray is strengthened refrigerating unit, and this device comprises chilling ring 1, inhalent siphon 2, inclination spout hole 3, annular slot 4, downtake 5.Chilling ring 1 is a belt tubulose, the circle side has inclination spout hole 3 in chilling ring 1, inclination spout hole 3 along chilling ring 1 inner periphery to uniform distribution, the effect of inclination spout hole 3 is to make in the water coolant that sprayed by inclined hole and the downtake vertically downward that the mobile synthetic gas produces flowing downward along the hand of spiral, annular slot 4 is located at chilling ring 1 downside, is positioned at the inboard of downtake 5 simultaneously.The vergence direction of inclination spout hole 3 is rotating shaft with the axis of chilling ring 1, is clockwise direction or arrangement counterclockwise.
In water coolant and the downtake 5 of ejection vertically downward the mobile synthetic gas carry out momentum exchange, make and cooling water droplet and mobile circle of contact of synthetic gas formation in the downtake cause synthetic gas to flow downward along the hand of spiral.Because it is very little to spray into the drop diameter of synthetic gas, therefore have very big specific surface area, the touch opportunity that this can increase synthetic gas and water has on the one hand increased synthetic gas flow process in downtake simultaneously, increased the residence time of synthetic gas in downtake, making conducts heat is strengthened.
