Embodiment
As Figure 1-4, the present invention provides a kind of absorption refrigeration unit, including absorber 1, and it is in institute
The bottom for stating absorber 1 is provided with opening, in addition to dirt collection tapping equipment 2, the dirt collection tapping equipment 2
The bottom of the absorber 1 is arranged on, and the dirt collection tapping equipment 2 includes being arranged on the absorber 1
Central position and the sewage sump 21 with being connected inside the absorber 1 on the downside of bottom.
Because the liquid level of solution in absorber internal cavity is higher, and solution is moved and even rotated,
Therefore can be effectively with the sewage sump being connected inside absorber by the setting on the downside of absorber bottom surface
Impurity in absorber solution is accommodated in the sewage sump by the sedimentation of gravity, it is therefore prevented that the cloth in unit
The blocking occurred in the parts such as liquid device due to there is a situation where for impurity；Solves absorption refrigeration unit
Clogging-preventing measures exist either uncontrollable factor had a great influence (due to manual operation) or for particle
The defects of blocking of less impurity does not have effective inhibitory action, it can either exclude well in production technology
Because impurity caused by uncontrollable remains, moreover it is possible to effectively prevent tiny impurity from blocking liquid distributor, solve
Fine impurities gather the blockage problem to unit liquid distributor.
The effect that the sewage sump 21 is arranged on to the central position of the bottom of absorber 1 is：By
Solution constantly flows in absorber, the probability of the impurity to be settled down with central position be present
It is greater than at marginal position, therefore the central position by the way that sewage sump to be arranged on to absorber bottom can have
Effect ground causes the impurity sedimentation in solution to fall into the sewage sump, improves blowdown, impurity removal, anticlogging
Effect and effect.

As shown in Figure 3-4, it is preferable that the sewage sump 21 is along the excessively described central axis of absorber 1
The vertical section of long side direction is shaped as triangular-section.By the way that the above-mentioned section of sewage sump is arranged into three
Angle section, i.e., the triangular prism extended along absorber short side direction can be effectively formed, and this is described
Two points in triangular-section are respectively positioned in the bottom face of the absorber 1, i.e. triangular prism upper table
Face is plane, is bonded with absorber bottom surface, and another point is the minimum point of vertical direction in triangular-section
As at triangular prism bottom.Because liquid level is higher in absorber, therefore solution internal flow
Relatively stable, such structure enables under gravity may be used with the fine impurities that solution circulation flow is moved
To be deposited in dirt collection trench bottom, and the impurity in absorber (is stored and assembled to the triangle by accumulation in bottom
At the lowest positions of shape prism), and then efficiently and conveniently discharge impurity from the absorber, improve
Contaminant removal effectiveness.
It is further preferred that short side direction and excessively described absorption of the sewage sump 21 along the absorber 1
The vertical section of the central axis of device 1 is shaped as rectangular shape.
Preferably, the dirt collection tapping equipment 2 also includes being arranged on the bottom of the sewage sump 21 (or most
Lower end) and be communicated to outside discharge pipe 22.Connected by being set in dirt collection trench bottom (or bottom)
The pollutions such as impurity effectively can be discharged sewage sump by the discharge pipe to outside.
Preferably, vent valves 23 are additionally provided with the discharge pipe 22.By setting vent valves
Effectively discharge process can be controlled with actual conditions as needed, play opening, close or increase
Or reduce and open aperture to control the purpose of emission flow and effect.
Preferably, in addition to it is arranged at the bottom of sewage sump 21 and is used for the solution in the sewage sump 21
Its outside discharge pipe 3 is expelled to, one end of the discharge pipe 3 is stretched out the bottom of sewage sump 21 and is higher than
The bottom inner bottom surface of the sewage sump 21, the other end are communicated to solution pump outside the absorber 1 (not
Show).By setting solution pump and its discharge pipe being connected with absorber can be effectively by absorber bottom
Complete the solution after absorption to be expelled in solution pump by discharge pipe, to realize that kind of refrigeration cycle provides bar
Part；Further, by the way that one end of discharge pipe to be arranged to bottom inner bottom surface (the i.e. bottom surface higher than sewage sump
Bottom), can effectively prevent that solution pump is drawn into the depositing contaminants of dirt collection trench bottom, reduce solution
Pump probability of malfunction caused by drawing solution impurity.
Preferably, the absorber 1 fills into absorbent by the way of upper hole sprays.Sprayed by upper hole
Mode can make larger solid impurity stay in spray bottom of the tube, primarily to after playing and preventing spray equipment
The effect of portion's aperture clogs.
Preferably, the absorbent of the absorption refrigeration unit is lithium bromide.This is the absorption system of the present invention

Refrigeration unit, it is controlled by blowdown process of the dirt collection tapping equipment 2 to the unit.Pass through profit
Energy is controlled with foregoing absorption refrigeration unit and by blowdown process of the dirt collection tapping equipment to unit
It is enough to be effectively accommodated in the impurity in absorber solution in the sewage sump by the sedimentation of gravity, it is therefore prevented that machine
The blocking occurred in the parts such as the liquid distributor in group due to there is a situation where for impurity；Solve absorption
The clogging-preventing measures of refrigeration unit exist either uncontrollable factor had a great influence (due to manual operation) or
The defects of blocking for the less impurity of particle does not have effective inhibitory action, it can either exclude to give birth to well
Because impurity caused by uncontrollable remains in production. art, moreover it is possible to effectively prevent tiny impurity from blocking cloth liquid dress
Put, solve blockage problem of the fine impurities accumulation to unit liquid distributor.
Preferably, when the dirt collection tapping equipment 2 includes discharge pipe 22 and vent valves 23, and work as
In the absorber 1 impurities accumulation for a period of time after, open the vent valves 23, carry out blowdown；Work as institute
When stating that solution impurity content is less in absorber 1, vent valves 23 are closed, stop blowdown.This is according to reality
The situation on border carries out the concrete operation step and form of blowdown by vent valves to dirt collection tapping equipment, can
Realization carries out blowdown when impurity level is larger, stops purpose and the effect of blowdown when impurity level is smaller.
Preferably, when solution content is less in the absorber 1, by the discharge pipe 22 from outer
Portion carries out the filling of (a certain amount of) solution to the inside of absorber 1, and solution in unit is maintained so as to reach
The purpose of the stabilization of amount and effect.
For those skilled in the art it is easily understood that on the premise of not conflicting, above-mentioned each advantageous manner can
