Description
Technical field
This utility model relates to coal chemical technology, particularly relates to a kind of water leg for gas generator.
Background technology
The gas generator that coal chemical industry or chemical fertilizer production supply coal gas are used, utilizes coal burning to react with steam generation and prepares coal gas.Water leg is the part in fixed-bed type gas generator, and its effect is to prevent coal at high temperature wall built-up, affects the properly functioning of gas generator.At present, the structure of water leg is varied, wherein the Chinese utility model patent of Patent No. ZL200620030823.X discloses a kind of water leg, including cylinder, top semicircle endless tube and lower semicircular endless tube, owing to top semicircle endless tube and lower semicircular endless tube are cut into two halves vertically by straight tube, the most again semicircle endless tube is bent into circular weld to cylinder body outer wall, this processing technology is considerably complicated, manufacturing cost is high, additionally, under the effect that joint and the connection mouth of a river of semicircle endless tube are in rising-heat contracting-cold, reliability is poor, water leakage situation often occurs.
Summary of the invention
This utility model is in order to solve weak point of the prior art, it is provided that a kind of manufacturing process is simple, low cost, highly reliable, the water leg of antileaking.
This utility model provides a kind of water leg, including cylinder, described cylinder be respectively arranged at two ends with the identical upper collecting chamber of structure and lower header up and down, upper collecting chamber and lower header are symmetrical arranged, the side of upper collecting chamber is provided with water outlet tube coupling, the side of lower header is provided with into water tube coupling, upper collecting chamber and lower header are all connected with cylinder one, the outer wall of cylinder is circumferentially uniform and is interval with multiple outer semi-circular tube, the upper end of outer semi-circular tube passes the bottom of upper collecting chamber and reaches in upper collecting chamber, the lower end of outer semi-circular tube passes the top of lower header and reaches in lower header, the two ends up and down of outer semi-circular tube are fixing with upper collecting chamber and lower header respectively to be connected.
Being equipped with the interior semi-circular tube being connected on cylinder body outer wall in described outer semi-circular tube, the upper and lower two ends of interior semi-circular tube all block, and are filled with high temperature resistant filler in interior semi-circular tube.
Using structure of the present utility model, upper collecting chamber and lower header to be all connected with cylinder one, weld seam is less, reduces leakage hidden trouble；The two ends up and down of outer semi-circular tube are simple with the connected mode of upper collecting chamber and lower header welding procedure compared with existing connected mode respectively simultaneously; weld seam is more firm; better tightness; also reduce leakage hidden trouble; reduce the shutdown maintenance rate of equipment; add the service time of equipment, increase economic efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and beneficial effect clearer, below in conjunction with the accompanying drawings this utility model embodiment is described in further detail.
As shown in Figure 1: this utility model provides a kind of water leg, including cylinder 1, described cylinder 1 be respectively arranged at two ends with the identical upper collecting chamber of structure 2 and lower header 3 up and down, upper collecting chamber 2 and lower header 3 are symmetrical arranged, upper collecting chamber 2 and lower header 3 are all connected with cylinder 1 one, the outer wall of cylinder 1 is circumferentially uniform and is interval with multiple outer semi-circular tube 4, the upper end of outer semi-circular tube 4 is through the bottom of upper collecting chamber 2, and extend in upper collecting chamber 2, the lower end of outer semi-circular tube 4 is through the top of lower header 3, and extend in lower header 3, the two ends up and down of outer semi-circular tube 4 are connected with upper collecting chamber 2 and lower header 3 respectively, and the two ends up and down of outer semi-circular tube 4 respectively with upper collecting chamber 2 and lower header 3 is fixing is connected, the side of upper collecting chamber 2 is provided with water outlet tube coupling 5, the side of lower header 3 is provided with into water tube coupling 6.
Being provided with the interior semi-circular tube 7 being connected on cylinder 1 outer wall in described every outer semi-circular tube 4, interior semi-circular tube about 7 two ends all block, and are filled with high temperature resistant filler 8 in interior semi-circular tube 7.
Owing to cylinder 1 and upper collecting chamber 2 use one to connect, cylinder 1 and lower header 3 use one to connect, and greatly reduce weld seam, also reduce the hidden danger leaked.In addition the weld seam between prior art China and foreign countries' semi-circular tube 4 and upper collecting chamber 2, weld seam between outer semi-circular tube 4 and lower header 3 is owing to being limited by shape of product and structure, cause the weld seam between outer semi-circular tube 4 and upper collecting chamber 2, weld seam ratio between outer semi-circular tube 4 and lower header 3 is relatively thin, firm not, and welding procedure is loaded down with trivial details, the outer semi-circular tube 4 of this utility model is simple with the welding procedure of upper collecting chamber 2 and lower header 3, weld seam is thick, substantially reduces the hidden danger leaked.
The big I of specification of the present utility model makes series of products according to the specification size of gas generator.
When work uses, current are entered in lower header 3 by tube coupling 6 of intaking, then flow in upper collecting chamber 2 by outer semi-circular tube 4, flow out finally by water outlet tube coupling 5, and current from bottom to top play good cooling effect, thus prevent coal at high temperature wall built-up.Along with the fire grate rotary slagging coutrol extrusion friction to cylinder 1, even if cylinder 1 inner wall abrasion is serious, do not interfere with normal production yet.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed utility model.This utility model claims scope and is defined by appending claims and equivalent.
